On this point, although known means principle proves effective, it also can further develop.In this application the present invention.
Summary of the invention
Task of the present invention is to provide a kind of forcing press of continuous operation, can manufacture good quality wood plate by this forcing press in especially economic mode.
For solving this task, the continous pressing machine of the present invention to the described type of beginning provides following instruction: pressure distribution plate utilizes adjustable power assisting device to be loaded to regulate the reaction force characteristic of pressure distribution plate by perpendicular to stripper plate plane earth.The present invention is at this first from such basis understanding, i.e. the characteristic of the forcing press of continuous operation can be optimized, and when applying pressure distribution plate, it comprises backing plate such as insulating pad if desired.When upper piston formula forcing press, therefore the stripper plate of bottom is not on the crossbeam of the pressure machine frame directly abutting in bottom, but arranges pressure distribution plate between which.According to these pressure distribution plates of the present invention now but be no longer configured to the element fixed, but by the supporting functions that pressure distribution plate realizes meet destination by adjustable power assisting device and corresponding specified criteria suitable.At this, the present invention has realized that the working method of the forcing press of continuous operation can be optimized, when realizing pressure distribution variable adaptive along forcing press length.Be additional to the compression cylinder (it acts on the stripper plate on stripper plate such as top) usually arranged, realize the best-fit to actual conditions within the scope of the invention, its mode is: the rigidity supporting the pressure distribution plate of other stripper plate carries out adaptation by power assisting device.When upper piston formula forcing press, compression cylinder acts on the stripper plate on top, thus abuts on described pressure machine frame pressure distribution plate arranged by the stripper plate of bottom between itself and pressure machine frame.Power assisting device is arranged on below pressure distribution plate in this case, thus it acts on the bottom side of pressure distribution plate.Generally can by the rigidity of pressure distribution plate and therefore indirectly also that the geometry in the characteristic of stripper plate and the pressure distribution of therefore suppressing in gap or compacting gap and variable dimension is suitable with specified criteria via power assisting device.Power assisting device can only work or also can facilitate on one's own initiative the elastic deformation of pressure distribution plate passively at this in the mode of the supporting member of (adjustable).
Preferred power assisting device is connected with at least one control device, and power assisting device utilizes described control device can be controlled according to one or more procedure parameter.In any case control device can be such as the process control computer all existed at this, or control device is connected with process control computer.Control device such as can be connected with compression cylinder and/or one or more sensor equally.Such as realize the self-reacting adaptation of pressure distribution in this way according to the pressed material pad that sails into and/or the characteristic of plate that has been extruded according to one or more procedure parameter.Because herein is provided a kind of dynamic machine, it realizes the dynamic change of pressure distribution according to other (outside) pressing parameter according to the various different characteristic sum of pressed material pad and/or wood plank to be manufactured.Therefore first there is such possibility, regulate compacting gap or pressure distribution as far as possible equably, the compacting gap namely not changing in forcing press length or significantly do not change." being close to principle " can be optimised.Within the scope of the invention but meet destination completely and change compacting gap or pressure distribution within the limits prescribed, thus not need all the time to follow " being close to principle " in previous section, but can leave be close to principle to obtain the effect specified completely.Pressing process can be optimized.Result can manufacture the wood plank with high quality, particularly high cross directional stretch rigidity when significant glue amount is saved at the same time.This principle is not only applied when thin plate or very thin plate, wherein realize around being close to principle in a particular manner so far, and apply particularly preferably in on-gauge plate or slab, wherein the application of pressure distribution plate and backing plate is if desired in secondary status so far.
In principle within the scope of the invention, the backing plate only already described is arranged between each single pressure machine frame, thus particularly can realize " being close to principle ", and is optimized by regulating reaction force characteristic by means of power assisting device.Preferably now but not only backing plate is set between each single pressure machine frame or between each cylinder piston device, but be connected on described pressure distribution plate stripper plate arranges additional backing plate and framework backing plate in the region of pressure machine frame between this stripper plate and pressure distribution plate in addition, wherein (reality) backing plate is arranged between each framework backing plate along forcing press longitudinal direction.Different from traditional forcing press with pressure distribution plate and hard-wired backing plate, therefore between each backing plate, additionally in framework level, arrange framework backing plate now, it seems to form framework extension.Be arranged on the framework backing plate (on the one hand) in framework level and be arranged on combination present adaptation realizing compression properties in particularly preferred mode together with power assisting device of backing plate between each framework (in addition on the one hand).If therefore backing plate is farthest unloaded by the retraction of power assisting device, so support basically by the realization of framework backing plate and therefore realize in a conventional manner in the region of pressure machine frame.If power assisting device is farthest used under other extreme case, thus pressure distribution plate obtains maximal support in the region of backing plate, thus backing plate seems above to be lifted the level of crossing framework backing plate, thus the power of cylinder piston device is not imported in framework backing plate, but is imported in the backing plate arranged between which and seems to achieve and be close to principle.Particular importance be only such fact, by changing the sensitive adaptation that the setting of power assisting device can realize forcing press characteristic.
Power assisting device such as can be configured to hydraulic regulating device, such as single-acting or double-acting hydraulic cylinder.Alternatively power assisting device also can be configured to electronic adjustment drive unit, such as electronic main shaft driving device.Power assisting device can be applied on pressure distribution plate just to applying pressure or also can connect like this, and not only pressure but also pulling force can both be applied on pressure distribution plate.All the time only can cause a kind of passive supporting or also can facilitate the flexible distortion of the active of pressure distribution plate.
According to another one suggestion regulation, therefore the width of pressure distribution plate arranges multiple power assisting device or adjusting device on forcing press width and also on the width of pressed material pad.They can as necessary by a common intermediate jack integratedly to the effect of pressure distribution plate.Always there is such possibility, namely multiple power assisting device or adjusting device or multiple row power assisting device or adjusting device are set in the length of forcing press.Thus there is such possibility, a power assisting device or a row power assisting device are set respectively between two pressure machine frames.Therefore, it is possible to change on the one hand the pressure distribution along forcing press length, alternatively but also there is such possibility and change pressure distribution along forcing press width when multiple power assisting device.
The setting of the power assisting device expected can such as manufacture regulation product startup stage or the preparatory stage determine.Pressing parameter particularly preferably but according to the rules realizes dynamically when forcing press runs, such as self-reacting adaptation.All the time in advance by experience or the best setting being determined regulation parameter by test.

Detailed description of the invention
Shown in the drawings of the forcing press for the manufacture of wood plank, especially MDF plate of continuous operation.In the forcing press of described continuous operation, by operative orientation A, sail forcing press into, the pressed material pad be made up of the wood particle (fiber of such as gluing) of gluing is pressed into wood plank.Forcing press has the stripper plate 1 on top and in forcing press bottom, has the stripper plate 2 of bottom in forcing press top, and the stripper plate on top and the stripper plate of bottom are configured to heating plate respectively.Stripper plate 1,2 is arranged in hydropress frame, and hydropress frame is combined by multiple pressure machine frame 3 arranged on forcing press longitudinal direction.Pressure machine frame is cut out part by steel plate in this embodiment and is realized in window construction mode.In addition, forcing press has the steel compressive zone 4 of circulation rotating in forcing press top and forcing press bottom, and described steel compressive zone arranges rolling element device if the situation lower support of rolling rod 5 is on stripper plate 1,2 between itself and stripper plate 1,2.Forcing press is configured to upper piston formula forcing press in this embodiment, this means, the stripper plate 1 on cylinder piston device 6 pairs of tops of multiple spread configuration works.Therefore in the region of each pressure machine frame 3, all arrange a row cylinder piston device 6, these cylinder piston devices are connected on the entablature 3a of pressure machine frame 3 on the one hand, are connected on the stripper plate 1 on top on the other hand.From 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.
Stripper plate 1,2 is connected to feedboard 1a, 2a that feed side is outstanding, and described feedboard is formed in the charging gap E that operative orientation A shrinks gradually, the adjacent compacting gap P be made up of stripper plate 1,2 on charging gap.This embodiment uses feedboard that is flexible, the elasticity of flexure to adjust variable charging profile.But also can use one or more feedboard be articulated and connected as an alternative solution, described feedboard is combined by multiple plate section be hingedly connected to each other alternatively.Lower feedboard 2b is bearing on the sill 3b of pressure machine frame 3 as the stripper plate 2 of bottom, and enterprising flitch 1a is connected on cylinder piston device 6 as the stripper plate 1 on top.
The stripper plate 2 of bottom is connected on the sill 3b of described pressure machine frame when arranging pressure distribution plate 7 between itself and the sill 3b of pressure machine frame.Pressure distribution plate 7 is equipped with backing plate 8 alternatively, and described backing plate is fixed on pressure distribution plate 7 between the pressure machine frame that each is adjacent along forcing press longitudinal direction.
Fig. 1 illustrates, the pressure distribution plate 7 with the backing plate 8 arranged alternatively to be arranged in whole crush-zone and to be especially arranged in the whole region of stripper plate 1,2.Therefore pressure distribution plate 7 and optional backing plate 8 arrange and are distributed on a region on forcing press longitudinal direction, and this region is greater than 90% of stripper plate 1,2 length and is also greater than 90% of the total length of stripper plate 1,2 and feedboard 1a, 2a in this embodiment.Therefore the application of pressure distribution plate is not only confined to the correction zone of forcing press outlet side, but not only in heat penetration district but also in correction zone, preferably also additionally at feed zone and accomplished in compressional zone thus.
The backing plate 8 only schematically shown in accompanying drawing preferably extends on the whole width of stripper plate 1,2 and/or feedboard 1a, 2a.Backing plate can be implemented as the continuous print backing plate circuit extended on plate width, to realize continuous print bearing-surface.But as an alternative solution, backing plate circuit also can be made up of multiple single bearing-surface be distributed on plate width.Details is not shown.Backing plate is always configured to insulating pad, prevents from thus carrying out too much heat transfer from by the stripper plate 1,2 heated to framework.In forcing press length, arrange multiple single pressure distribution plate 7, pressure distribution plate 7 to be in an illustrated embodiment separately positioned between two pressure machine frames 3 and to be bearing on the sill 3b of pressure machine frame 3.But also can arrange continuous print pressure distribution plate as an alternative solution, it crosses over multiple pressure machine frame or all pressure machine frames.This is not shown in the accompanying drawings.
In the embodiment shown in figure 2, between two adjacent pressure machine frames, arrange a backing plate 8 as insulating pad respectively, this backing plate is positioned at the center between two adjacent pressure machine frames 3.
In the embodiment as replacement shown in Fig. 3, for each pressure machine frame 3 configures 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 bracing or strutting arrangement in both cases, and it is connected on pressure machine frame.Therefore power assisting device 9 is not preferably bearing on ground individually, but self-supporting is on forcing press.
In the embodiment pressing Fig. 2, the power of two adjacent cylinders 6 imports to same in the backing plate 8 of center arrangement substantially, and in the embodiment pressing Fig. 3, power imports to configuration to the backing plate centering of each single cylinder piston device.This is illustrated simplifiedly by arrow.
Not only as in the case of the embodiment according to fig. 2 but also according in the embodiment of Fig. 3, pressure distribution plate utilizes power assisting device 9 to load, and it is configured to adjusting device 9, the such as hydraulic cylinder of hydraulic pressure in this embodiment.Power assisting device 9 is applied on pressure distribution plate 7 perpendicular to stripper plate plane (from below), thus 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 pressure distribution therefore in forcing press inside changes according to different squeezing parameter.
For this reason, power assisting device 9 and control device 10 (its at this can be process control computer) be connected, and this computer controls remaining constricted zone particularly compression cylinder 16 and also read various different sensor or similarity piece and the control of pressure charge machine generally.Via this control device 10, power assisting device 9 can changeably, automatically adapt to adaptive from various different squeezing parameter, thus the dynamic adaptation of machine can be realized in the fabrication process.
The stripper plate 2 of the embodiment middle and lower part shown in Fig. 2 and 3 abuts on pressure distribution plate 7, only arrange backing plate 8 between which, and Figure 4 and 5 illustrate different embodiments, the stripper plate 2 of its middle and lower part is connected on pressure distribution plate 7 in the region of pressure machine frame 3, arranges additional framework backing plate 11 between the stripper plate 2 and pressure distribution plate 7 of bottom simultaneously.Therefore the backing plate 8 already discussed is arranged between framework backing plate 11 along forcing press longitudinal direction.Therefore framework backing plate 11 forms framework support or framework extension.By means of power assisting device 9, can adaptive power import delicately now.If therefore cylinder body 9 is farthest unloaded or is retracted, so backing plate 8 seem ineffective and power import realize in a conventional manner in the region of pressure machine frame.If cylinder body 9 is rolled away from the contrary and therefore backing plate 8 is lifted, the extreme case underframe backing plate 11 so other is ineffective, thus support only realizes via backing plate 8 and no longer realizes via framework backing plate 11.Various different possibility is represented by shown arrow.Always pass through now the variable adaptation of the corresponding control realization to cylinder body 9 to pressing process.
By of the present invention, such as in the accompanying drawings shown in forcing press utilize the glue amount obviously reduced not only can manufacture thin plate and ultra thin plate, also particularly preferably manufacture the slab of that thickness is 4mm to 30mm, preferably 6mm to 30mm, that there is standard substantially transverse tensile strength.
