Description

Polymer of unusual materials and their manufacturing methods

The present invention relates to polymer and manufacture method thereof with kinds of materials polymerization formation.Utilizing a polymeric example of the present invention is exactly the polymer that is in secondary end flat board that the road inductive of the vehicle (being levitation train-translator) by the rail running formula linear electric motor of freely travelling under the very little setting height state in road surface uses etc.

As everyone knows, for example, the traffic tool are very important, and wherein the traffic tool such as railway are because transportation in a large number at a high speed, and therefore different with the automobile transportation, it occupies crucial status.

; if when information is transmitted speed up; reach desirable railway transport speed up; then its vibration or noise are with very important; in addition; because factors such as the increase of the engineering work load of bringing along with the big section driving in the tunnel piercing of underground railway etc. and price risings, the linear electric motor vehicle of rail running formula is owing to have peace and quiet, friction and can dwindle many advantages such as section in tunnel etc. and favored day by day, and partly enters the practicability stage.

Yet, primary side for the linear electric motor vehicle of this rail running formula, the secondary end slab construction that makes it to produce electric convolution and form driving force, its material must be that good conductivity and high permeability are arranged, and, when producing quite powerful driving force, also must bear shearing force or peeling force as its counter-force.As only using a kind of metallic material, therefore then can't obtain having the metallic material of this specific character, will adopt and to have the polymer of different kinds material fluid-tight engagement of good conductive and high permeability each other as the flat board of secondary end in the technical merit of present stage.

For example, employing with mild steel 1. plate as metal body with high permeability materials, will be as the aluminium sheet polymerization with it of the metal body of another material with good conductive, utilize press machine to make it moulding, machining is carried out at the two ends of this Mild Sheet Steel of clamping again, and countersunk head screw is screwed into Mild Sheet Steel from aluminium sheet, and two dull and stereotyped bindings are one, perhaps, utilize the blast complex method that aluminium sheet is combined closely with it and form composite plate etc. for Mild Sheet Steel.

But, as mentioned above, in order to make the secondary end flat board have the supporting function of the counter-force of the powerful driving force that acts on repeatedly for high frequency, must have can and the huge resistivity that contends with of the shearing force of interface parallel direction, simultaneously, the peeling force for above-below direction also must have enough big resistivity.

Aspect such as underground railway particularly, must bear because of dispelling the heat relatively poor or the thermal effect of mechanics vibration generation or additional peeling force, therefore, as described above, dull and stereotyped with two with after the press machine moulding fluid-tight engagement, the structure that is combined with each other with screw-driving or blast all can not have permanent, enough big resistivity.

In using the fastening structure of press machine moulding and screw, the combination force of machinery or the shortcoming of fastening force are that loosening in time and gradually tendency is arranged, and adopt the compound very costliness of manufacturing expense that has of exploding, the also non-remunerative problem of cost.

In addition, use the underground railway in tunnel, for example corrosion appears near meeting such as underground railway the seashore or harsh condition such as pour water makes environment significantly worsen, and can produce on the mating face of Mild Sheet Steel and aluminium sheet and corrode, can not keep the function of secondary end flat board for a long time, this also is its bad place.

The objective of the invention is to solve the problem of the metal polymer of the different kinds material that above-mentioned conventional art makes, particularly to provide a kind of under the thermal effect influence of powerful shearing stress that acts on repeatedly or fierceness, dissimilar metals engages each other closely face and also can not produce the changing of the relative positions or peel off, can keep tightening state, and low cost of manufacture, the polymer of the foreign material of any variation can take place in its function for a long time hardly.

Illustrated embodiment is the situation of the secondary end flat board of rail running formula linear electric motor vehicle, in the embodiment shown in Figure 1A, 111 expressions are as the polymeric secondary end flat board of foreign material of the present invention, as the Mild Sheet Steel 2 of the metal body of first kind of material with high permeability and the aluminium sheet with good conductive 3 mechanical bond on mating face 11 as the metal body of at an upper portion thereof second kind of material.

Can find out from Figure 1B of the form of representing two flat boards 2,3 respectively, on plane 11a on the Mild Sheet Steel 2, make the lower end taper, the cross section is the ditch shape recess 7 of V font, these recesses 7 are processed to true dip direction, make its a side internal surface 6 form the face that overhangs (in the drawings for along with the face that extends in horizontal direction upward).The true dip direction of recess 7 and configuration thereof can be made various changes according to the difference of design condition.

On the other hand, on the lower plane 11b of aluminium sheet 3, make the lower end be tapered, the cross section is the protuberance 9 of V font, these protuberances 9 are outstanding with true dip direction, make its side 8 form outstanding face (being the face that extends in horizontal direction along with downwards in the drawings) downwards.

The mutual alignment of above-mentioned recess 7 and protuberance 9 is corresponding, and shape, size are all consistent.In Figure 1B, flat board the 2, the 3rd is represented with separated state, in fact, as hereinafter described, when making polymer, protuberance 9 casts in the recess 7, or adopts and dull and stereotyped 3 dull and stereotyped relatively 2 usefulness rollers are added the ways that pressure handle protuberance 9 is pressed in the recess 7 make closely combining of machinery of two flat boards.Like this, polymer 111 forms as one with great fastening force, much less vertically, even for horizontal shearing force enough big resistivity is arranged also, simultaneously, also has resistivity for the peeling force that thermal effect produced that is caused by temperature variation etc.

In said structure, when among the figure not the linear electric motor vehicle of expression with given levitation height when on set secondary end flat board 111, travelling, can produce electric convolutions by aluminium sheet 3, thereby produce driving force.Aluminium sheet 3 is in the huge counter-force effect of the driving force that vertically is subjected to this moment, yet because the firm mechanical bond of the downward protrusion surface 8 of the face that overhangs 6 of recess 7 and protuberance 9, much less vertical, even also have enough big resistivity for the shearing force on the vertical with it direction, in addition, the face 6 that overhangs also can resist with the firm mechanical bond of downward protrusion surface 8 because the powerful peeling force of the above-below direction that thermal effect such as temperature variation cause prevents that (floating) variable height from surpassing the specified altitude of setpoint distance.Simultaneously, because Mild Sheet Steel 2 is combined closely with the mating face 11 of aluminium sheet 3, even therefore moist wind or pour water etc. can not cause corrosion yet, just can not produce so between the two and peel off, can keep the intimate-association state stipulated fully, the vehicle of linear electric motor also can travel by design code.

Secondly, in the embodiment shown in Figure 2, on the mating face of polymer 112, the jut 10 of neutral position to upper process all made in the inside of all recesses 7 of Mild Sheet Steel 2 one sides, the mating face of recess 7 has been increased more, therefore can increase the power of opposing shearing force.When aluminium sheet 3 plastically was pressed into recess 7, this jut 10 made the flowability of plasticity improve, and had to improve the effect of filling.

In polymer embodiment illustrated in fig. 3 113, the face that overhangs 6 of recess and the downward protrusion surface of protuberance 8 form with P-P faces title, so protuberance 9 is outstanding to the direction that departs from the P-P face.This embodiment is very effective under situation about being installed on the straight-line travelling part etc., and low cost of manufacture.

In polymer embodiment illustrated in fig. 4 114, the recess 7 of swallow-tail form and protuberance 9 be the mutual edge distance certain intervals mutually.As hereinafter described, this embodiment can freely design recess and protuberance with respect to the mating face on longitudinal and transverse or true dip direction, and manufacture cost is also low.

In polymer embodiment illustrated in fig. 5 115, on the downward projection 8 of the overhang part 6 and the protuberance 9 of recess embodiment illustrated in fig. 17, on the whole surface on recess 7, protuberance 9 and mating face, all make the pitch littler secondary recess of its pitch than this overhang 6 and downward protuberance 8, like this, Mild Sheet Steel 2 can be combined closely more firmly with aluminium sheet 3.In this embodiment, can obtain huge resistivity to shearing force or peeling force.

In polymer shown in Figure 6 116, for the mating face of the Mild Sheet Steel 2 of the various embodiments described above and aluminium sheet 3 are the dissimilar metals patterns of directly combining closely mutually, should prevent owing to both different producing on the mating face of causing of corrosion potential difference are corroded, for example, adopt the thinner thin layer 12 of middle insertion ratio insulating material with improve between the two prevent to corrode function.In this embodiment, Mild Sheet Steel 2 and aluminium sheet 3 also can be closely fastening by thin layer 12, can fully guarantee the resistivity to shearing force or peeling force.

In polymer shown in Figure 7 117, below the isolation layer 12 embodiment illustrated in fig. 6, to Mild Sheet Steel 2 coating one deck anticorrosive ground coats 12 ' make it between wherein installing.In this embodiment, can improve the corrosion protection function more.

In addition, in this embodiment, it is also fine that anticorrosive coating is coated on the aluminium sheet 3 effect, and the binder that can also be coated with the corrosion protection function replaces anticorrosive coating.

About recess with the face of overhanging and configuration mode with protuberance of downward protrusion surface, can be as shown in Figure 8, on vertical or horizontal with equidirectional configuration, also can be as shown in Figure 9, on same direction, be configured to zigzag fashion, can also dispose obliquely as shown in Figure 10.

Only represented Mild Sheet Steel 2 at Figure 11 to polymer 120(shown in Figure 13) in, on plane 11a on the Mild Sheet Steel, leave straight flute shape recess 7 abreast.The sectional shape of each recess 7 comes down to identical with the sectional shape of recess shown in Figure 27.On plane 11a on this piece Mild Sheet Steel, make the ditch 14 that intersects with recess 7, can make sulcus of chiasm 14 and recess 7 square crossings.In this embodiment, the aluminium sheet of not expressing among the figure 3 has and the same protuberance that includes downward protrusion surface (this face is along the face that overhangs 6 of chase 7) shown in Figure 2, also has the protuberance that fills up above-mentioned sulcus of chiasm 14 inside fully simultaneously.In this embodiment, for resistivity, owing to the existence of sulcus of chiasm 14 is strengthened along vertical external force of recess 7.

In the Mild Sheet Steel 2 of polymer shown in Figure 14 121, make extension 16 at the open part of its recess 7 at certain intervals in wave shapely.In order to make waveform extension part 16, can resemble Figure 15 extremely as shown in Figure 17, both sides at ditch shape recess 7 are made punching 15 etc. at certain intervals, make along a part of material of recess 7 and above recess 7, producing plastic deformation near the punching 15, its result, on the open part of recess 7, formed extension 16 at certain intervals.Like this, imbed aluminium sheet 3(Figure 18 in the recess 7) protuberance 9 combine more firmly with Mild Sheet Steel 2.Utilize Fig. 9 to method shown in Figure 180, can obtain the geometric fingerprinting stress on all directions.

Certainly, Shi of the present invention executes Qing Kuang And and is not limited only to the various embodiments described above, for example, with respect to face of overhanging and downward protrusion surface, can also adopt various patterns such as several sections zigzag jogs are set on short transverse.

In addition, the also available other materials of Mild Sheet Steel and aluminium sheet replaces.

And and, polymeric applicable object is not only the secondary end flat board of the linear electric motor vehicle of rail running formula, and require the polymer of firmly tight fastening combination all can be suitable for for all, the for example contact line and the lathe of under the very big condition of violent slip or vibration, temperature variation, working, and all applicable on other members.

Shearing force that polymer of the present invention acts on repeatedly for high frequency or peeling force also can stable for extended periods of time firm locking state, can very stably keep playing remarkable effect aspect the function of linear electric motor vehicle etc. according to design.

In addition, the mating face of two flat boards, because protrusion surface forms a kind of labyrinth sealing state for the effect of combining closely of the face of overhanging downwards, therefore, even be corrosive around under the ambient condition of gas, the corrosion body can not invaded the mating face yet, like this, can play preventing to produce the effect of peeling off on the mating face of a kind of material and another kind of material.

For on the mating face of Mild Sheet Steel 2, processing V-arrangement ditch shape recess, can adopt the method for the following stated with the face of overhanging.

At first, on blank Mild Sheet Steel 2, process mating face 11a as shown in figure 19, smooth, on institute's certain portions of this mating face 11a, with two sides shown in Figure 20 smooth and circumferential surface have seamed edge, when side surface rotates with fixed pressure extrusion And and limit squish lip by the moulding roller 20 of deciding taper, then as shown in Figure 20, on the 11a of the mating face of Mild Sheet Steel 2; Form sharp-pointed bump 24 by a side, then form low ebb part 25, form small bump 26 at opposite side at downside.

And and, utilize roller with optimum shape, number of times according to the rules carries out this forming process repeatedly, just can make the low ebb part 25 that a side has the bump 24 of specified altitude.

Such as shown in figure 21, as the surperficial And that columnar roller 27 is compressed low ebb part 25 and when on one side rotating it, the bump 24,26 of low ebb part 25 1 sides and opposite side will become smooth equally with the mating face 11a of general place, form the V-arrangement cross section of inclination, just constituted so have the ditch shape recess 7 of the face of overhanging 6.

Therefore, the shaping operation that needn't carry out the difficulties such as cutting of downward protrusion surface can be made the face of overhanging 6.

Secondly, when as shown in Figure 2 recess 7 of processing, as shown in Figure 19, for mating face 11a through processing smooth blank Mild Sheet Steel 2 in advance, on the 11a of mating face, such as shown in figure 22, can and rotate it simultaneously with the belt shape type roller 20a compressive engagement face 11a ， And that V-arrangement cross section ditch is arranged on the side face of garden, can process inside and have chevron convex portion 28, both sides have the ditch of vertical sidewall and bump 29,29.By carrying out forming operation shown in Figure 22 repeatedly, just can make the paddy portion and the bump 29,29 of prescribed depth.Moreover, such as shown in figure 23, by the garden side face axially is pressed on the bump 29 of both sides for the garden tubular moulding roller 27a of straight line, And makes it to rotate the number of times of regulation simultaneously on 29, and then bump 29,29 is pressed into the inboard, just can make that both sides have with chevron convex portion 28 is the recess of the face that overhangs 6,6 of border, outward-dipping extension.

In the embodiment shown in Figure 24, on the garden side face of belt wheel shape roller 20a shown in Figure 22, make a recess 30 every certain intervals, when this roller 20a rotates on the bottom surface of formed ditch shape recess 7, such as shown in figure 25, every certain intervals, constitute a protruding part 31.Therefore fill up the protuberance and the jut 31 of the aluminium sheet 3 of recess 7 inside and combine closely, so just increased for recess 7 resistivity of external force longitudinally.If the recess 30 with on the convex portion replacement roller 20a then will form a sunk part to replace protruding part 31 on recess 7.Resistivity also can increase in this case.

When processing as shown in Figure 4 the swallow-tail form recess and during protuberance, such as shown in figure 26, processing the cross section on the 11a of the mating face of Mild Sheet Steel 2 in advance is square projection 40, then, such as shown in figure 27, utilize outer garden side face to have the cross section on projection 40, to push for the roller 41 of M shape ditch, the both sides And that clamps projection 40 with the inner side surface of M shape ditch makes it to rotate the number of times of regulation simultaneously, thus, projection 40 just become end face and have the projection 40 of the recess in M type cross section '.Once more, the both sides of such as shown in figure 28, when the moulding roller 42 extruding projections 40 ′ And that will have tubular garden, garden side face rotate the number of times of regulation, projection 40 ' just become smooth projection of end face 40 "; at this projection 40 " just constitute the face 43,43 that overhangs.Like this, do not need, just can make swallow-tail form cross section part according to design by cutting.

The processing that also can use the same method of the downward protrusion surface of the aluminium sheet 3 that combines with the face of overhanging of Mild Sheet Steel 2.

Figure 29 to Figure 31 is illustrated on the Mild Sheet Steel 2 processing and has another kind of method with the recess of recess shown in Figure 47 analogous shapes.When using this method, such as shown in figure 29, utilize tubular roller 45 pairs of ditches in garden to carry out plastic working, both sides at it form bump 46, secondly, such as shown in figure 30, in part corresponding to the ditch 7 that processes, the calendering roller 48 that employing has annular triangular section ditch 47 rolls Mild Sheet Steel 2.Like this, the bump 46 of ditch 7 both sides just as 46 ' shown in like that, to the inboard plastic deformation of ditch.At last, such as shown in figure 31, when utilizing garden tube roller 49 calendering Mild Sheet Steels 2, bump 46 ', so just process the ditch shape recess 7 that there is the face of overhanging 6 both sides again to the inboard distortion of ditch.

At Figure 32 A to the embodiment shown in Figure 39, the recess of on Mild Sheet Steel 2, making 7, it is not the ditch shape among the previous embodiment, but has the garden hole shape of the face of overhanging 6, shown in Figure 32 A and Figure 32 B.On aluminium sheet 3, shown in Figure 33 A and Figure 33 B, like that, also make inverted cone through hole 51.Recess 7 is consistent with the mutual alignment of through hole 51.These recesses 7 and through hole 51 are not necessarily non-to be that garden shape, rectangle or ellipse garden, other shapes are also passable.

Prepare Mild Sheet Steel 2 as described above and aluminium sheet 3, such as shown in figure 34, recess 7 is overlapped two flat boards with through hole 51 concentric And, secondly, such as shown in figure 35, forgeable soft material (for example fixing pin of making of aluminium 52) is inserted in recess 7 and the through hole 51, along arrow F direction with its jumping-up.Like this, as among Figure 36 with 52 ' representing, soft material fills up recess 7 and hole 51, reaches the effect of fixing pin, aluminium sheet 3 and Mild Sheet Steel 2 combine securely.

In example shown in Figure 37, the recess 7 of Mild Sheet Steel 2 is made of the hole, stepped shaft garden that the inside part diameter increases.This step portion just forms overhang 6.

When making such recess 7, such as shown in figure 38, employing cutting edge 54 can be at solid line position and towards the cutter 55 that circles round that moves freely between the imaginary line position that radial direction is outwards given prominence to.At first, such as shown in figure 39, cutting edge 54 is bored a hole on Mild Sheet Steel 2 with the state to the inboard retraction of radial direction, and is such as shown in figure 40 then, and cutting edge 54 is released towards the outside of radius aspect, carries out hole processing.Like this, can process as shown in Figure 37 ladder recess 7.Moreover, if, gradually cutting edge 54 is released to the outside of radial direction, then can process recess such shown in Figure 32 B 7 along with the carrying out of hole processing.

Figure 41 to Figure 43 is illustrated in the another kind of method that processes recess 7 in the Mild Sheet Steel 2.When making in this way, such as shown in figure 41, at first will there be the pressing plate 58 in hole, garden 57 to be fixed on the Mild Sheet Steel 2, secondly such as shown in figure 42, in the position of the circular hole 57 of pressing plate 58, drift 60 is squeezed in the Mild Sheet Steel 2.Like this, around drift 60, and be in the scope in the hole, garden 57 of pressing plate 58, the material of Mild Sheet Steel 2 forms bump 61.Then, such as shown in figure 43, take out drift 60, with dull and stereotyped 62 be pressed in down Mild Sheet Steel 2 above, then bump 61 is to the distortion of the inboard in hole, at the inside of the recess 7 formation face that overhangs.

Make to have and combine closely, can also adopt following method with the aluminium sheet 3 of the protuberance of downward protrusion surface and the Mild Sheet Steel 2 that processes the ditch shape recess that has the face of overhanging with said method or cutting working method.

The polymeric situation of now just making shape shown in Figure 2 describes: at first, such as shown in figure 44, on Mild Sheet Steel 2 and by the situation difference, make after the recess 7 of being with the face 6 that overhangs in two side, in order to produce in a large number, such as shown in figure 45, for example can be by release liners such as gypsum 63, with a pair of Mild Sheet Steel 2,2 the back side is combined into one relatively, then, such as shown in figure 46, with the Mild Sheet Steel 2 that is made of one, 2 put into casting mold 65, the aluminium water 3 ' injection of the state of dissolving be will be in advance from the cast gate 67 of casting mold 65, aluminium water 3 ' be full of the mating face outer surface of Mild Sheet Steel 2,2 and the cavity between the casting mold 65 made.

At this moment, utilize well-known conventional process, can make aluminium water 3 ' along all recesses 7,7 ... each face 6 that overhangs flow to each corner.

Like this,, after aluminium water 3 ' cooled and solidified, open casting mold 65 through scheduled time, such as shown in figure 47, just can obtain on the outer surface of Mild Sheet Steel 2,2, aluminium sheet 3 is at its whole recesses 7,7 ... in, along each closely square of embedding of face 6 that overhangs.Then,, cut off aluminium sheet 3, just obtain secondary end flat board shown in Figure 48 along release liner 63.

In addition, also can be between Figure 45 and operation shown in Figure 46 of the foregoing description, at Mild Sheet Steel 2, the rust resisting paint that coating is made up of the insulating material that can prevent iron and aluminium electro erosion on 2 the mating face 11, after forming the anticorrosive property film on the mating face 11, putting into casting mold 65 again, be molded into aluminium water 3 '.

About a kind of material in the relative casting mold, the molten casting of another kind of material is not certainly to dissolve easily the person for well.

Utilizing the described plastic flow method in back also can carry out Mild Sheet Steel 2 is connected with the tight of aluminium sheet 3.

In order to implement this method, such at first as shown in figure 49, the Mild Sheet Steel 2 of the recess 7 that has the face of overhanging 6 is made in preparation on the 11a of mating face, such as shown in figure 50 simultaneously, prepares to have the plate shaped aluminium sheet 3 of mating face 11b again.

Secondly, like that, with the mating face 11a of two boards 2,3,11b is relative shown in Figure 51, and two plates are connected, and utilizes the press arrangement that does not illustrate among the figure or rolls roller etc., applies impacting force equably according to the direction shown in the arrow F among Figure 51 comprehensively.Like this, plastic flow makes the material of the aluminium sheet 3 that yield point is low flow into recess 7,7 ... the position, when continuing pressurization, then shown in Figure 52 like that, the material of the mating face 11b of aluminium sheet 3 will be along the face of overhanging 6,6 ... enter in the recess 7,7 of Mild Sheet Steel 2, even discharge impacting force F, two flat boards 2,3 still can keep intimate-association state.

And and, in the operation that applies impacting force F,, make it to heat up by utilizing the mating face 11b of heating such as thermatron aluminium sheet 3, more can guarantee the recess 7,7 that the plastic flow by aluminium sheet 3 causes to Mild Sheet Steel 2 ... interior inflow campaign.

When in the end being shaped, just can obtain desirable goods by finishing processing etc.

Secondly, such shown in Figure 55, make recess 7 consistent with projection 66 mutual alignments, Mild Sheet Steel 2 is relative with aluminium sheet 3, the top of projection 66 is embedded in the recess 7, such shown in Figure 56 for another example, relative Mild Sheet Steel 2, utilize press machine or calendering roller, on aluminium sheet 3, apply uniform impacting force F comprehensively.Like this, same as the previously described embodiments, each projection 66 of aluminium sheet 3 produces plastic flow, flows in the recess 7 of Mild Sheet Steel 2 along the face of overhanging 6, and is such shown in Figure 57.

At this moment, by the caused chock effect in bottom protrusion inclined-plane owing to recess 7, the inflow that makes plastic flow by the projection 66 that carries out along the face 6 that respectively overhangs cause can more truly have carry out with guaranteeing And and, as mentioned above, because the volume of the recess 7 of the volume ratio Mild Sheet Steel 2 of the projection of counting from the mating face 11b of aluminium sheet 3 66 is slightly bigger, therefore, the material of the aluminium sheet 3 that is caused by impacting force F also can more truly have towards the plastic flow in the recess 7 with guaranteeing and carry out, thereby more can guarantee the intimate-association state of both machineries.

Same as the previously described embodiments, in this case, when applying impacting force F, by pressing to projection 66,66 heating of fixed temperature to aluminium sheet 3, the yield stress of aluminium sheet 3 reduces, and more can guarantee the realization of flowing.In addition, even material contracts the time appears in cooling in applying the impacting force process, because the volume of the volume ratio recess 7 of projection 66 is big slightly, therefore also can be at the material of realizing aluminium sheet 3 after the contraction mobile to recess 7 in, accomplishing does not have the gap, obtains the more firm polymer of combining closely.

In addition, in produced like this polymer,, therefore can significantly improve for the shearing slip of in-plane or the resistivity of peeling off (particularly shear and slide) of above-below direction because big with respect to the bonded area of the Mild Sheet Steel 2 of aluminium sheet 3.

In conjunction with Figure 58 to Figure 62 polymeric other method of combining closely of making is described.

When using this method, like that, prepare Mild Sheet Steel 2 shown in Figure 58, it and the mounting bracket 70 that will install on the track sleeper of linear electric motor vehicle are beforehand with and are integral.This Mild Sheet Steel 2 processes a recess 7 with the face of overhanging 6 on the longitudinal direction of its mating face 11a central authorities, processing the cross section in its bi-side is the chase 71 of circular arc.

Secondly, shown in Figure 59 like that, will with recess sectional shape and measure-alike trapezoidal aluminium bar 72 in the recess 7 that vertically is pressed into Mild Sheet Steel 2.

Can also need not do like this, and it is interior as aluminium bar 72 that the aluminium water that dissolves is molded into recess 7, as a whole also passable with 2 one-tenth of Mild Sheet Steels,

Secondly, such shown in Figure 60, preparation is as the aluminium sheet 3 of second metal body, 3, its cross section is the L type, on the one end, integrally make chase 71 with the side of Mild Sheet Steel 2, the teat 73 of 71 correspondences, other end 74 are made an inclined-plane, and aluminium sheet is heated to predetermined temperature, make it to expand, with each teat 73 of aluminium sheet closely and chase 71 combinations of Mild Sheet Steel 2, on the face of overhanging 6, make two terminal surfaces 74 keep certain intervals then, the placement of terminal surface 74 positions is appropriate, make the configuration relatively mutually of a pair of aluminium sheet 3,3.Secondly, shown in Figure 61, like that, on the aluminium bar 72 the recess 7 of Mild Sheet Steel 2 in and the part of this aluminium bar 72 that is close to aluminium sheet 3,3, go out welding portion 75, Mild Sheet Steel 2, aluminium bar 72, aluminium sheet 3,3 four are combined as a whole with the aluminium built-up welding.

Then with its cooling, utilize aluminium sheet 3, the contraction that 3 cooling produces and the thermal contraction of built-up welding part 74, make aluminium sheet 3,3 in transverse shrinkage, its teat 73 just embeds in the chase 71 of Mild Sheet Steel 2 securely, therefore, Mild Sheet Steel 2 is whole intimate-association state with aluminium sheet 3,3 and tightens up, and can obtain the secondary end flat board as final products shown in Figure 62 by built-up welding part 75 being carried out cutting.Secondary end flat board as product can keep the firm intimate-association state of aluminium sheet 3 on Mild Sheet Steel 2 for a long time, also can fully keep the shearing slip of in-plane or the resistivity of peeling off of above-below direction.

Secondly, in the embodiment shown in Figure 63 to Figure 65, such shown in Figure 63, also be to process on the coupling 11a on recess 7 with the face of overhanging 6 and the Mild Sheet Steel 2 that is processing chase 71,71 on the bi-side in advance relatively, utilize the aluminium sheet 3,3 of combining closely the pair of L type being installed of teat 73 and chase 71.At this moment, not as previous embodiment, in recess 7, do not insert aluminium bar.And make flange 76 outstanding in recess 7 at opposite one end of the teat 73 of each aluminium sheet 3.

Secondly, such shown in Figure 64 in the state of Figure 63, the aluminium water of in recess 7, casting and dissolving from the gap of 76 of two flanges, after the cavity between recess 7 and the flange 76 was full of, two flanges just melted knot together, again its were placed cooling.Because aluminium sheet 3,3 pre-heated effects produce thermal shrinkage in its cooling procedure, teat 73 just embeds in the corresponding chase 71, and Mild Sheet Steel 2 just forms the closely fastening state that is combined as a whole with aluminium sheet 3,3.In addition, in the recess 7 of Mild Sheet Steel 2, because the effect of the metallic solution 77 that has solidified, Mild Sheet Steel 2 forms the closely fastening state that is combined as a whole with aluminium sheet 3,3.For another example shown in Figure 65 like that, by cutting is carried out at built-up welding polymerization position 77, become equally with the surface of aluminium sheet 3,3, just as Figure 62, can obtain product polymer as the combination shown in Figure 65.This polymer is the same with the polymer shown in Figure 62, become the close-connected securely polymer of aluminium sheet 3 and Mild Sheet Steel 2, can be fully, change ground chronically, and keep resistivity for the peeling force of the shearing force of in-plane effect or above-below direction effect.
