Description

Water blocking device of embryo opening machine

The invention relates to a steel processing equipment, in particular to a water blocking device of a blank opening machine.

In the steel processing process, the steel material heated by the heating furnace will be hot rolled by a blank opening machine to produce a roughly H-shaped steel blank.

An existing blank opening machine includes two shaft seats spaced in a left-right direction, an upper roller shaft pivotally connected between the shaft seats in the left-right direction and capable of rotating relative to the shaft seats, and one along the left-right direction The direction is pivotally connected between the shaft seats and can rotate relative to the shaft seats and is disposed under the upper roller shaft, a lower roller shaft, two upper support rods, and two lower support rods. The upper support rods are spaced apart on opposite sides of the upper roller shaft in a front-rear direction and connected between the shaft seats. The lower support rods are spaced apart on opposite sides of the lower roller shaft in the front-rear direction and connected between the shaft seats. The heated steel material is rolled forward between the upper roller shaft and the lower roller shaft in the front-rear direction and processed. The upper support rods and the lower support rods can prevent the steel material from buckling due to the phenomenon of warping during processing, and accidentally hit the upper roller shaft or the lower roller shaft.

In this process, cooling water will be sprayed on the upper roller shaft and the lower roller shaft to absorb heat energy to keep the upper roller shaft and the lower roller shaft from softening or damaging due to excessive temperature. However, the cooling water sprayed on the upper roller shaft will flow down to the steel material being processed due to gravity, which in turn causes the upper half of the steel material to receive the cooling water to accelerate cooling and differ from the cooling rate of the lower half. Different cooling rates will cause uneven texture of the finished product and affect the quality of the product.

Therefore, the object of the present invention is to provide a water blocking device for a blank opening machine that can prevent cooling water from flowing to a steel material being processed and thereby improve product quality.

Therefore, the water blocking device of the embryo opening machine of the present invention includes two shaft seats spaced apart in a left-right direction, and one pivotally connected between the shaft seats in the left-right direction and capable of being relative to the shaft seats Rotating upper roller shaft, and two supporting rods. The support rods are spaced apart on opposite sides of the upper roller shaft along a front-rear direction perpendicular to the left-right direction and connected between the shaft seats. The water blocking device of the embryo opening machine includes two blocking units respectively arranged on the supporting rods, each blocking unit includes a plurality of fixed seats, and a blocking group.

The fixing seats of each blocking unit are arranged at intervals in the left-right direction and installed on the corresponding support rods. Each fixing base has an inner side wall disposed on the side of the corresponding support bar adjacent to the upper roller shaft, an outer side wall disposed on the side of the support bar opposite to the inner side wall, and a side wall connected to the inner side wall The connecting wall between the outer side walls. The inner side wall, the connecting wall and the outer side wall jointly define an installation groove with the opening facing downward and suitable for accommodating the supporting rod of the part.

The blocking group of each blocking unit has a drainage member extending in the left-right direction and connected to the fixing seats, and a resisting member connected to the drainage member. The drainage member has an upper arc portion and a lower arc portion connected below the upper arc portion. The cross section of the upper arc portion and the lower arc portion along the left-right direction is arc-shaped, and together defines a first drainage groove with an opening facing the other blocking unit and facing upward. The abutting member has a connecting portion connected to the lower arc portion, and an abutting portion opposite to the connecting portion. The abutment portion extends toward the other stop unit and is inclined upward, and has an abutment edge matching the shape of the upper roller shaft. Due to gravity, the abutting member is pressed down so that the abutting edge is tightly attached to the surface of the upper roller shaft. When cooling water is sprayed from above the upper roller shaft, the cooling water is blocked by the abutting member and does not flow in The upper roller shaft is led into the first drainage groove and discharged from the first drainage groove along both sides of the left-right direction.

The effect of the present invention is that the abutment pieces of the blocking units block the cooling water and are discharged from the first drainage grooves to prevent the cooling water from flowing to the steel material being processed, thereby improving product quality.

Referring to FIGS. 1 and 2, an embodiment of the water blocking device of the embryo opening machine of the present invention includes two shaft seats 11 spaced apart along a left-right direction D1, and one pivotally connected to the left-right direction D1 An upper roller shaft 12 between the shaft seats 11 and rotatable relative to the shaft seats 11 and two support rods 13. The support rods 13 are arranged at intervals on the opposite sides of the upper roller shaft 12 along a front-rear direction D2 perpendicular to the left-right direction D1 and connected between the shaft seats 11. The water blocking device of the embryo opening machine includes two blocking units 2 respectively disposed on the supporting rods 13, each blocking unit 2 includes a plurality of fixed seats 3, a mounting member 4, and a blocking group 5.

Referring to FIGS. 3, 4 and 5, the fixing bases 3 of each blocking unit 2 are arranged at intervals along the left-right direction D1 and are installed on the corresponding support bars 13. Each fixing base 3 has an inner side wall 31 disposed on the side of the corresponding support bar 13 adjacent to the upper roller shaft 12, an outer side wall 32 disposed on the side of the support bar 13 opposite to the inner side wall 31, a A connecting wall 33 connected between the inner side wall 31 and the outer side wall 32 and two first set screws 34 screwed to the respective outer side walls 32. The inner side wall 31, the connecting wall 33 and the outer side wall 32 together define an installation slot 35 which is arc-shaped and has an opening facing downward and is suitable for accommodating a part of the support rod 13. The first set screws 34 are screwed on the outer side wall 32 and penetrate into the respective mounting grooves 35 and abut against the corresponding support rod 13. In this embodiment, the number of the first set screw 34 of each fixing base 3 is two, but it may be one or more than three.

The mounting member 4 of each blocking unit 2 is disposed in the corresponding mounting groove 35 and extends along the left-right direction D1. The mounting member 4 is disposed on the top of the respective support rod 13 and has a curved top surface 41 protruding upward. The top surface 41 cooperates with the corresponding mounting groove 35.

Among the fixing bases 3 of each blocking unit 2, each fixing base 3 disposed on the two sides of the corresponding mounting member 4 along the left-right direction D1 also has a second screwed to the respective connecting wall 33 Stop screw 36. The second set screw 36 penetrates the respective mounting groove 35 from the connecting wall 33 and abuts against the top surface 41 of the mounting member 4.

The blocking group 5 of each blocking unit 2 has a drainage member 51 extending along the left-right direction D1 and welded to the fixing bases 3, a contact member 52 connected to the drainage member 51, and a drainage member The upper clamping member 53, the lower clamping member 54, a plurality of clamping screw sets 55, and a dredging member 56 that are overlapped by the member 51 and the abutment member 52.

The drainage member 51 has an upper arc portion 511, a lower arc portion 512 connected below the upper arc portion 511, and a clamping portion 513 connected to the lower arc portion 512 and overlapping with the abutment member 52 . The cross sections of the upper arc portion 511 and the lower arc portion 512 along the left-right direction D1 are arc-shaped and together define a first drainage groove 514 that opens upward toward the other blocking unit 2 and upward.

The abutting member 52 has a connecting portion 521 that overlaps with the clamping portion 513 and is indirectly connected to the lower arc portion 512, and an abutting portion 522 opposite to the connecting portion 521. The abutment portion 522 extends toward the other stop unit 2 and is inclined upward, and has an abutment edge 523 matching the shape of the upper roller shaft 12.

The upper clamping member 53 and the lower clamping member 54 are respectively disposed above and below the clamping portion 513 of the drainage member 51. The clamping screw sets 55 pass through the upper clamping member 53, the connecting portion 521, the clamping portion 513, and the lower clamping member 54 and are locked to produce clamping between the abutment member 52 and the drainage member 51 effect.

The drainage member 56 extends along the left-right direction D1 and is disposed below the lower arc portion 512 of the drainage member 51, and defines a second drainage groove 561 along the left-right direction D1. Both ends of the drainage member 56 along the front-rear direction D1 are welded to the lower clamping member 54 and the lower arc portion 512, respectively. The lower arc portion 512 also has a plurality of through holes 515 communicating with the second drainage groove 561.

In this embodiment, the material of the abutment pieces 52 is a mixture of rubber and polyurethane, but it may also be other soft wear-resistant materials, and is not limited to such materials.

During processing, the upper roller shaft 12 rotates with the lower roller shaft (not shown) located below and rolls the steel material below, and the cooling water used to cool the upper roller shaft 12 is sprayed from above the upper roller shaft 12 To cool the upper roller shaft 12. Due to gravity, the abutments 52 drive the corresponding fixed seat 3 to deflect relative to the corresponding support rod 13. The abutment pieces 52 are thus pressed down on the upper roller shaft 12, and the abutment edges 523 can still keep close to the surface of the upper roller shaft 12 when rotating. The cooling water sprayed from above the upper roller shaft 12 is blocked by the abutment pieces 52 and does not flow to the steel material being processed. The cooling water flows along the stopper group 5 and is guided into the first drainage groove 514 and discharged by the first drainage groove 514 along both sides of the left-right direction D1, resulting in the effect of diverting the water flow. The cooling water can also flow into the second drainage grooves 561 through the perforations 515 of the drainage pieces 51, and then be discharged by the second drainage grooves 561 along both sides of the left-right direction D1, to further enhance the effect of diverting the water flow.

Since the water flow does not flow to the steel material being processed, the steel material will not cause the problem of different cooling rates as described in the prior art because of the cooling water, which makes the texture of the finished product uniform and improves the product quality. Since the water flow does not flow to the steel material being processed, the temperature of the steel material can be maintained at a relatively high temperature, so the temperature of the steel material before being processed by the blank opening machine is relatively reduced. That is to say, the heating furnace can heat the steel to a lower temperature, which can reduce energy consumption and produce a cost-saving effect.

Without the mounting member 4, the abutment members 52 can still drive the corresponding fixing base 3 to deflect relative to the corresponding support rod 13. However, by matching the top surface 41 of the mounting member 4 with the corresponding mounting groove 35, a better deflection effect can be produced.

In addition, since the abutment pieces 52 are pressed down by gravity, in order to prevent the abutment piece 52 from being biased at an excessively large angle and causing device instability, the first stop screws 34 penetrate into their respective installation slots 35 and against the corresponding support rod 13, thereby limiting the angle of deflection by the structure. The second set screws 56 penetrate into the respective mounting grooves 35 and abut against the top surface 41 of the mounting member 4, thereby increasing the friction force with the mounting member 4.

In summary, the water blocking device of the embryo opening machine of the present invention blocks the cooling water by the abutment pieces 52 of the blocking unit 2 and is discharged by the first drainage grooves 514 to prevent the cooling water from flowing into the process To improve the product quality, so it can really achieve the purpose of cost invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as This invention covers the patent.
