Abstract
The invention provides a device used for acting surface pressure on a moving workpiece (such as wood plate, rubber rail, plastic rail or similar workpiece). The invention aims at prolonging the service life of the pressing plates (3, 3a); the pressing plate is arranged in a reaction area of a belt-typed press; the necessary pressure is transferred onto the working area of the extrusion belt (1) from the pressing plate through a rolling body which is circularly moving on a cirque rail (6) and then is transferred onto the workpiece.
Description
The present invention relates to be used for (as the timber plate at the workpiece of advancing, rubber rail material, on the plastic rail material) apply a kind of device of surface pressing, here but at least one compressive zone that goes in ring is a workpiece pressing, simultaneously, operating pressure is to be applied on the work section of compressive zone by means of pressing plate, in addition, in the pressing plate scope, be provided with spaced apart at interval, be in the work section of being assigned of pressing plate and compressive zone that friction links, the rolling element that overall with by compressive zone is extended, these rolling elements output from pressing plate on the track of a closure is transferred the importing end of getting back to pressing plate, and perhaps they are disposed at the surface towards compressive zone work section of pressing plate regularly.
A kind of device of described kind has been known (DE3608 487 G
2), under the situation of this device, each rolling element is to have roller section a series of rollers that directly adjoin, that form with assembly as one to form, and roller is arranged in rows mutually in the exit position in this roller section, and is supported rotationally with respect to adjacent roller.
Yet rolling element also can be constituted as and roll bar, and they extend through the overall with of compressive zone.
Pressing plate is usually made by steel, and should also can dispose heating-cooling device.
Because the pressure of necessary pressing plate is by being applied on the work section of compressive zone with the coefficient rolling element of pressing plate in the conversion zone of the forcing press of continuous operation, and be passed on the workpiece therefrom, therefore between pressing plate and rolling element, produce a kind of friction that causes the acting in conjunction parts depreciation, in order to improve the life-span of these parts, should keep this friction as small as possible.
The purpose of this invention is to design the device of kind described in a kind of introduction, so that improve the life-span of pressing plate.
According to the present invention, this purpose solves by following manner, pressing plate make it be provided with the processing groove that intersects with the coefficient surface of rolling element by a kind of cutting working method, these processing grooves form a latticed system of oil cavity, simultaneously, by the smooth mountain portions ground that rolls the gauge oil cavity by cold forming with hardened.
By according to processing measure of the present invention, pressing plate keep a kind of micro-geometrical structure with the coefficient surface of rolling element, this micro-geometrical structure has formed the latticed system that strengthens the oil cavity of lubricated prerequisite as a kind of on the one hand, simultaneously on the other hand, by smooth peak cold forming and the cold hardening that rolls generation, formed sizable local surfaces of the lubricated oil duct gauge of back-up roller kinetoplast.By based on the smooth cold forming that rolls the peak that is produced, extended seven times by the total surface that local surfaces is formed.
Because described processing measure is taked on the acting in conjunction surface that is in running with rolling element to pressing plate, makes pressing plate form a kind of stress state, this stress state will cause the arching of a kind of hull shape of soleplate.
In order to eliminate this stress state, according to a kind of further step of the present invention, pressing plate is symmetrical in longitudinal center's face to be formed, and the upper and lower limit interface of pressing plate is all by a kind of machining, make it be provided with the processing groove that intersects, these processing grooves form the latticed system of oil cavity.Roll by smooth, the mountain portions of gauge oil cavity ground is by cold forming and hardened.
Pressing plate of making by this way and processing is not only stressless and such possibility is provided, promptly, after the first processed surface abrasion, by the upset face of pressing plate, promptly come into operation and allow and the rolling element co-operation in the second processed surface.
Therefore the life cycle of pressing plate is doubled when forcing press turns round.
Further feature of the present invention is drawn by dependent claims.
Embodiments of the invention are depicted in the accompanying drawing, and are illustrated below.
The vertical cross section skeleton diagram of a double belt press of Fig. 1;
Fig. 2 presses the larger scale map of area I I of the double belt press of Fig. 1;
The view on the surface that is cut processing of Fig. 3 pressing plate has the machining locus of the represented cutting tool of wire;
Fig. 4 presses a section of IV among Fig. 3-IV line;
Micrograph in the pressing plate working surface region that Fig. 5 extremely amplifies;
The partial view of the working surface that is cut processing of Fig. 6 pressing plate;
Fig. 7 is according to a kind of mutation form of Fig. 6 structure.
Pointed dual-band extruder has the compressive zone 1 of annular among Fig. 1 and Fig. 2, and it can be made and be directed by revolving roll 2 by steel plate.Revolving roll 2 is positioned in the extruder base rotationally, also arranges to have a top board and a lower platen 3,3a in the extruder base.
Between the work section that the quilt of pressing plate and compressive zone 1 is assigned, be provided with rolling element dividually at interval, by these rolling elements, the extruding force that is produced by pressing plate 3 is passed on the work section of compressive zone 1.
Between the work section of compressive zone 1, workpiece 5 is directed and is applied in surface pressing by dual-band extruder.
Rolling element 4, they do not have connection ground each other or their axostylus axostyle can have flexible device to be connected at side by a kind of mutually, and are directed on the closed orbit in the pressure support 6, and closed orbit is represented with dotted line in Fig. 1.Rolling element 4 is for this reason from pressing plate 3, and the output 7 of 3a is transferred the importing end 8a that gets back to pressing plate.
Each oil cavity 9 has a small constructional depth, and it approximately can be 0.1mm or smaller.
Supply with the lubricant that pressing plate is provided with the surface 8 of oil cavity and in its way, outwards and on the operative orientation 16 of extruder move in order to brake or to hinder, under examples of implementation according to Fig. 4, machining locus 17 operations of cutting tool are to be not parallel to the edge surface 18 of pressing plate, but the longitudinal centre line 19 of the surface to be machined 8 of sensing pressing plate.
Fig. 4 is drawn by figure to press a section of IV-IV line in the magnifying state presentation graphs 3 extremely, and machining locus 17 has step, and it is to be formed in this wise, so that lubricant is hindered on the operative orientation 16 of extruder in its way.Lubricant paths is to represent by a fine rule 20 that has arrow.Can learn that thus the slow down motion of lubricating oil of each step 21 of the serrate profile of machining locus is so that lubricant is maintained in the scope of working surface 8 of pressing plate.
The stress state that is occurred by the surface 8 that processes pressing plate 3 or 3a can be eliminated thus, that is, outer surface 22 and 23 equally also is cut to be processed into and has the work groove that intersects depicted in figure 1, and is and then rolled by smooth.After 8 wearing and tearing of surface, can use surface 22 and 23 as working surface.
