Summary of the invention
Task of the present invention provides a kind of forcing press of continuous operation, can make the good quality wood plate with especially economic mode by this forcing press.
For solving this task, the present invention provides following instruction to the continous pressing machine that starts said type: the pressure distribution plate utilizes adjustable power assisting device to be loaded so that regulate the reaction force characteristic of pressure distribution plate perpendicular to the stripper plate plane earth.At first from such basis understanding, i.e. the characteristic of the forcing press of continuous operation can be optimized at this in the present invention, and when the applying pressure distribution plate, it comprises for example insulating pad of backing plate in case of necessity.Therefore under the situation of upper piston formula forcing press, the stripper plate of bottom is not directly to abut on the crossbeam of pressure machine frame of bottom, but between them, arranges the pressure distribution plate.Yet these pressure distribution plates no longer constitute fixing element now according to the present invention, but it is suitable with corresponding specified criteria through adjustable power assisting device to meet the destination through the firm and hard existing support functions of pressure distribution.The present invention can be optimized in the working method that this has realized that the forcing press of continuous operation, in the time can realizing along the pressure distribution of forcing press length variable adaptive.Be additional to the compression cylinder (it acts on stripper plate for example on the stripper plate on top) of common setting; Realize the best-fit to actual conditions within the scope of the invention, its mode is: the rigidity that supports the pressure distribution plate of other stripper plate is carried out adaptive through power assisting device.Under the situation of upper piston formula forcing press, compression cylinder acts on the stripper plate on top, thereby the stripper plate of bottom is arranged between itself and pressure machine frame under the situation of pressure distribution plate and abutted on the said pressure machine frame.Power assisting device is arranged on pressure distribution plate below in this case, thereby it acts on the bottom side of pressure distribution plate.Generally can the rigidity of pressure distribution plate is also suitable with the characteristic of stripper plate and the geometry of therefore suppressing pressure distribution or compacting gap in the gap and size variable ground and specified criteria indirectly with therefore via power assisting device.Power assisting device is in this strain that can be only works or also can facilitate the pressure distribution plate on one's own initiative with the mode of the supporting member of (scalable) passively.
Preferred power assisting device is connected with at least one control device, and power assisting device utilizes said control device to be controlled according to one or more procedure parameters.In any case control device can for example be the process control computer that all exists at this, perhaps control device is connected with process control computer.Control device for example can be connected with compression cylinder and/or one or more sensor equally.For example realize the self-reacting adaptive of pressure distribution according to one or more procedure parameters in this way according to the characteristic of the pressed material pad that sails into and/or the plate that has been extruded.Therefore a kind of dynamic machine is provided, and it realizes the dynamic change of pressure distribution according to the various characteristic of pressed material pad and/or timber plate to be made with according to other (outside) compacting parameter.Therefore such possibility at first occurs, regulated compacting gap or pressure distribution, the compacting gap that promptly on forcing press length, does not change or significantly do not change as far as possible equably." being close to principle " can be optimised.In the scope of regulation, change compacting gap or pressure distribution yet meet the destination within the scope of the invention fully, thereby be not to follow " being close to principle " all the time in the part in front, be close to principle to obtain the effect of regulation but can leave fully.Pressing process can be optimized.Make under the situation that can be the at the same time significant glue amount of result is saved and have high quality, particularly the timber plate of high cross directional stretch rigidity.This principle is not only at thin plate or use under the situation of plate as thin as a wafer; Wherein realize around being close to principle with special mode so far; And particularly preferably in using in on-gauge plate or the slab, wherein pressure distribution plate and the application of backing plate in case of necessity are in less important status so far.
In principle within the scope of the invention be that the backing plate of only having described already is arranged between each single pressure machine frame, thereby particularly can realize " being close to principle ", and is optimized through regulating the reaction force characteristic by means of power assisting device.Yet preferably not only between each single pressure machine frame or between each cylinder piston device backing plate is being set now; But stripper plate is arranging between this stripper plate and the pressure distribution plate that additional backing plate is to be connected on the said pressure distribution plate under the situation of framework backing plate in the zone of pressure machine frame in addition, and wherein (reality) backing plate is arranged between each framework backing plate along the forcing press longitudinal direction.With different at traditional forcing press with pressure distribution plate and hard-wired backing plate, therefore the framework backing plate is being set on the framework level additionally between each backing plate now, as if it constitute the framework extension.The combination that is arranged on the framework backing plate (on the one hand) on the framework level and is arranged on backing plate between each framework (in addition on the one hand) realizes the adaptive of compression properties with preferred especially mode now with power assisting device.If therefore through the retraction quilt unloading farthest of power assisting device, supporting realizes and therefore in the zone of pressure machine frame, realizes in a conventional manner through the framework backing plate backing plate basically so.If power assisting device is farthest used under other extreme case; Thereby the pressure distribution plate obtains maximal support in the zone of backing plate; Thereby backing plate as if by on lift the level of crossing the framework backing plate; As if thereby the power of cylinder piston device is not imported in the framework backing plate, but be imported in the backing plate of between them, arranging and realized being close to principle.Particular importance only be such fact, can realize adaptive to the sensitivity of forcing press characteristic through the setting that changes power assisting device.
Power assisting device can for example constitute hydraulic regulating device, for example single-acting or double-acting hydraulic cylinder.Alternatively power assisting device also can constitute electronic adjusting drive unit, for example electronic main shaft driving device.Power assisting device can affact on the pressure distribution plate just to exerting pressure or also can connect like this, and feasible not only pressure but also pulling force can both be applied on the pressure distribution plate.All the time can only cause a kind of passive supporting or also can facilitate the flexible distortion of the active of pressure distribution plate.
On the width of pressure distribution plate and therefore according to another one suggestion regulation, on the forcing press width and a plurality of power assisting devices or adjusting device also be set on the width of pressed material pad.They can pass through a common intermediate jack integratedly to the effect of pressure distribution plate in case of necessity.Always there is such possibility, a plurality of power assisting devices or adjusting device or multiple row power assisting device or adjusting device promptly are set on the length of forcing press.Thereby there is such possibility, a power assisting device or a row power assisting device are set between two pressure machine frames respectively.Therefore can change on the one hand, yet also exist such possibility under the situation of a plurality of power assisting devices, to change pressure distribution alternatively along the forcing press width along the pressure distribution of forcing press length.
The setting of the power assisting device of expectation can be for example the product of making regulation the startup stage or the preparatory stage confirm.Yet especially preferably according to the rules compacting parameter when forcing press moves, realize dynamically, for example self-reacting adaptive.All the time confirm the optimal setting of regulation parameter in advance through experience or through test.
Continous pressing machine can also be provided in the outstanding feedboard of feed side with known mode itself except that stripper plate; Said feedboard is formed on the operative orientation charging gap of shrinking gradually, last feedboard and/or down feedboard be supported in the cylinder piston device loading on the crossbeam of pressure machine frame equally.Be in the feedboard zone, not to be provided with what this belonged to category of the present invention according to pressure distribution plate of the present invention and backing plate.Yet in scope of the present invention be alternatively equally, said go up feedboard or down feedboard under the situation of arranging pressure distribution plate (it has backing plate in case of necessity) between the corresponding crossbeam of this feedboard and pressure machine frame, be connected on the corresponding crossbeam of said pressure machine frame.
Especially preferably continous pressing machine is configured to upper piston formula forcing press; Wherein, The cylinder piston device is to the stripper plate on top and in case of necessity last feedboard is carried out work; In this case, the stripper plate of bottom rests on the sill of said pressure machine frame under the situation of arranging the pressure distribution plate between the sill of itself and pressure machine frame.The present invention also can implement in lower piston formula forcing press in principle.What meet purpose all the time is that the pressure distribution plate is connected with frame fixation, for example twists to connect.Backing plate can (if existence) constitute the drying finger that on corresponding plate width, extends, and it perhaps has at the continuous bearing-surface that extends on the plate width or has a plurality of single bearing-surfaces that on the plate width, distribute.In any case these bearing-surfaces are arranged on the forcing press longitudinal direction between the pressure machine frame and therefore and arrange with respect to the operative orientation of cylinder piston device with staggering.The special preferred orientation of cylinder piston device is in frame plane.
What belong to category of the present invention is, between per two adjacent pressure machine frames, locatees one or more backing plates respectively in the center.Thereby can be for example between per two adjacent pressure machine frames, locate a drying finger respectively in the center.Yet also be to be arranged on the both sides of pressure machine frame at least for each two backing plate of configuration of each pressure machine frame and said backing plate in category of the present invention with on the forcing press longitudinal direction, leaving the pressure machine frame predetermined distance respectively.Thus, from having the pressure machine frame of setting cylinder piston row above that, the power of cylinder piston row does not directly import on the crossbeam of the pressure machine frame that is positioned at vertical lower, but the backing plate of as if opening towards the equi-spaced apart in both sides obliquely.This mode also makes the power supporting-point in the forcing press longitudinal direction double.
In any case backing plate is given the surface of stripper plate as protuberance with the configuration that predetermined size protrudes in the pressure distribution plate, thereby on the forcing press longitudinal direction, produces discrete supporting-point.
Yet the present invention also comprises some forms of implementation in principle, wherein abandons backing plate fully, thereby stripper plate directly or indirectly abuts on the pressure distribution plate, thereby provides on the corresponding surface on plane basically.Yet backing plate preferably is set and the framework backing plate especially preferably additionally is set.
The pressure distribution plate can be provided with on the whole zone of forcing press basically, and for example the whole zone neutralization at stripper plate is provided with in the whole zone at feedboard in case of necessity.This means that said pressure distribution plate is arranged in the zone, this zone is at least corresponding to stripper plate 70%, preferred at least 90%.Also a plurality of single pressure distribution plates can be set on forcing press length, wherein, pressure distribution plate is separately positioned between two adjacent pressure machine frames and is bearing on the corresponding crossbeam of pressure machine frame.Yet continuous pressure distribution plate alternatively can be set, and it crosses over a plurality of pressure machine frames or all pressure machine frames.Stripper plate generally, it is also referred to as support plate, constitutes the supporting structure across framework.These pressure distribution plates or support plate can be cast sheet or steel plate.What meet purpose all the time is that the width of pressure distribution plate (roughly) equals the stripper plate width.
Content of the present invention also comprises a kind of method that is used for making with the forcing press of the continuous operation of said type the timber plate.This method is characterised in that, in order to change pressing process or in order to obtain variable reaction force characteristic, the pressure distribution plate utilizes power assisting device to be loaded perpendicular to the stripper plate plane earth.Power assisting device utilizes control device to regulate according to one or more procedure parameters and control and regulate according to the characteristic of the characteristic of pressed material pad to be extruded and/or the pressed material plate that has been extruded when needed.Can realize self-reacting control or self-reacting adjusting at this.

The specific embodiment
What continuous operation had been shown in the accompanying drawing is used to make timber plate, the especially forcing press of MDF plate.In the forcing press of said continuous operation, will on operative orientation A, sail pressed material pad forcing press, that process by the wood particle (the for example fiber of gluing) of gluing into and be pressed into the timber plate.Forcing press has the stripper plate 1 on top and in the forcing press bottom, has the stripper plate 2 of bottom in forcing press top, the stripper plate on top and the stripper plate of bottom are configured to heating plate respectively. Stripper plate 1,2 is arranged in the hydropress frame, and hydropress frame is combined by a plurality of pressure machine frames of on the forcing press longitudinal direction, arranging 3.Pressure machine frame is cut out part by steel plate in this embodiment and is realized with the window construction mode.In addition, forcing press has the steel compressive zone 4 of circulation rotation in forcing press top and forcing press bottom, said steel compressive zone itself and stripper plate 1, rolling element device such as rolling rod 5 are set between 2 the situation lower support on stripper plate 1,2.Forcing press is configured to upper piston formula forcing press in this embodiment, this means, the stripper plate 1 on 6 pairs of tops of cylinder piston device of a plurality of arrangement settings works.Therefore a row cylinder piston device 6 all is set in the zone of each pressure machine frame 3, these cylinder piston devices are connected on the entablature 3a of pressure machine frame 3 on the one hand, are connected on the other hand on the stripper plate 1 on top.Visible by accompanying drawing, cylinder piston device 6 is separately positioned in the frame plane of pressure machine frame 3, thus the operative orientation of cylinder piston device in other words working face be arranged in frame plane.
On stripper plate 1,2, be connected feed side outstanding feedboard 1a, 2a, said feedboard is formed in the charging gap E that shrinks gradually on the operative orientation A, the compacting gap P that adjacency is made up of stripper plate 1,2 on the charging gap.This embodiment uses feedboard flexible, the elasticity of flexure to adjust variable charging profile.But also can use one or more feedboards that are articulated and connected as alternative, said feedboard is combined by a plurality of plate sections hingedly connected to one another alternatively.Following feedboard 2b is bearing on the sill 3b of pressure machine frame 3 as the stripper plate 2 of bottom, is connected on the cylinder piston device 6 as the stripper plate 1 on top and go up feedboard 1a.
The stripper plate 2 of bottom is connected on the sill 3b of said pressure machine frame under the situation of arranging pressure distribution plate 7 between the sill 3b of itself and pressure machine frame.Pressure distribution plate 7 is equipped with backing plate 8 alternatively, and said backing plate is fixed on the pressure distribution plate 7 between the adjacent pressure machine frame of forcing press longitudinal direction at each.
Fig. 1 illustrates, and having alternatively, the pressure distribution plate 7 of the backing plate 8 of setting is arranged in the whole crush-zone and especially is arranged in the whole zone of stripper plate 1,2.Therefore pressure distribution plate 7 is being provided with on the forcing press longitudinal direction and is being distributed on the zone with optional backing plate 8, this zone greater than stripper plate 1,2 length 90% and in this embodiment also greater than 90% of the total length of stripper plate 1,2 and feedboard 1a, 2a.Therefore the application of pressure distribution plate not only is confined to the correction zone of forcing press outlet side, but not only in the heat penetration district but also in correction zone, preferably also additionally at feed zone and accomplished in the compressional zone thus.
The backing plate that only schematically shows in the accompanying drawing 8 preferably extends on the whole width of stripper plate 1,2 and/or feedboard 1a, 2a.Backing plate can be implemented as the continuous backing plate circuit that on the plate width, extends, to realize continuous bearing-surface.But as alternative, the backing plate circuit also can be made up of a plurality of single bearing-surfaces that are distributed on the plate width.Details is not shown.Backing plate always is configured to insulating pad, prevents thus to carry out too much heat transfer from heated stripper plate 1,2 to framework.Be separately positioned between two pressure machine frames 3 and be bearing on the sill 3b of pressure machine frame 3 in that a plurality of single 7, one pressure distribution plates 7 of pressure distribution plate are set on the forcing press length in an illustrated embodiment.But as alternative continuous pressure distribution plate can be set also, it crosses over a plurality of pressure machine frames or all pressure machine frames.This is not shown in the accompanying drawings.
In embodiment shown in Figure 2, a backing plate 8 as insulating pad is set respectively between two adjacent pressure machine frames, this backing plate is positioned at two centers between the adjacent pressure machine frame 3.
In the embodiment of conduct replacement shown in Figure 3, for each pressure machine frame 3 disposes two backing plates 8 respectively, these two backing plates are respectively to leave the both sides that the predetermined distance of pressure machine frame is arranged on pressure machine frame 3.Power assisting device 9 is bearing in pressure machine frame or is bearing on the bracing or strutting arrangement under both of these case, and it is connected on the pressure machine frame.Therefore power assisting device 9 preferably is not bearing on the ground individually, but self-supporting is on forcing press.
In pressing the embodiment of Fig. 2, the power of two adjacent cylinders 6 imports to same in the backing plate 8 of center arrangement basically, and in pressing the embodiment of Fig. 3, power imports to the backing plate centering that each single cylinder piston device is given in configuration.This illustrates through arrow simplifiedly.
Not only in according to the embodiment of Fig. 2 but also in the embodiment according to Fig. 3, the pressure distribution plate utilizes power assisting device 9 to load, and it constitutes adjusting device 9, the for example hydraulic cylinder of hydraulic pressure in this embodiment.Power assisting device 9 affacts on the pressure distribution plate 7 perpendicular to stripper plate plane (from the below), thereby can change the reaction force characteristic of pressure distribution plate 7.In this way, the rigidity of pressure distribution plate 7 can be changed and therefore distribute in the forcing press pressure inside and change according to different squeezing parameter.
For this reason; Power assisting device 9 is connected with control device 10 (it can be a process control computer at this), and remaining constricted zone of this computer control is compression cylinder 16 and also read various sensor or similarity piece and the control of pressure charge machine generally particularly.Via this control device 10, it is adaptive with various squeezing parameter that power assisting device 9 can adapt to ground changeably, automatically, thereby in manufacture process, can realize the dynamic adaptation of machine.
The stripper plate 2 of the embodiment middle and lower part shown in Fig. 2 and 3 abuts on the pressure distribution plate 7; Between them, only arrange backing plate 8; And Figure 4 and 5 illustrate different embodiment; The stripper plate 2 of its middle and lower part is connected in the zone of pressure machine frame 3 on the pressure distribution plate 7, simultaneously between the stripper plate 2 of bottom and pressure distribution plate 7, arranges additional framework backing plate 11.Therefore the backing plate of having discussed already 8 is arranged between the framework backing plate 11 along the forcing press longitudinal direction.Therefore framework backing plate 11 constitutes framework support or framework extension.By means of power assisting device 9, can adaptive delicately power import now.If unloading farthest of cylinder body 9 so quilt or withdrawal, backing plate 8 seems ineffective and power importing realization in a conventional manner in the zone of pressure machine frame so.If cylinder body 9 is rolled away from the contrary and therefore backing plate 8 be lifted, ineffective at other extreme case underframe backing plate 11 so, realize and no longer realize via backing plate 8 thereby only support via framework backing plate 11.Various possibility is represented through shown arrow.Always realized variable adaptive to pressing process now through corresponding control to cylinder body 9.
