It makes, the cutting member processing of the industries such as device for switching and light industry.Although the plate shearing machine type used at present is more, from operation principle
Substantially similar on structural shape, usually lower slide is fixed, and workpiece to be processed is sent to by shear machine worktable
Cutter intersects the position of error articulation with bottom knife, and power passes to upper tool post through bent axle, and upper tool post is upper and lower in rail plate
Movement, so as to which cutter be driven to move up and down, completes the shearing to workpiece to be processed.
When carrying out shear using plate shearing machine, rear material stopping device is usually set, but when shearing plate is wider, due to rear plate
Dead weight and it is sagging, it is sagging after plate can not contact striker plate, back material stopping cannot play a role or its positioning accurate at this time
Degree can not ensure.Many times, staff is sheared using setting-out, and such setting-out is cut out the plate precision and less come
It is good, while time-consuming and laborious, inefficiencies are sheared using setting-out.In view of the above problems, a variety of retainers are had been developed that in the prior art
Mode, it is most of using pneumatic material retaining device, but the complex structural designs of existing material-supporting device, processing are cumbersome, of high cost, and
Retainer distance is big, when blanking flitch lid of lying do not live.
Such as, Chinese Patent Application No. is：201320833175.1 the applying date is：On December 17th, 2013, innovation and creation name
Referred to as：A kind of pneumatic rear materials supporting device of plate shearing machine, the material-supporting device of this application include rack, and the rack is equipped with lubricating substance
Plate, the side of rack are equipped with fulcrum, and the fulcrum is equipped with the bracket of two parallel triangles, upper and lower gas is equipped with below bracket
Cylinder, the bottom end of the upper and lower air cylinders are connect with rack, and upper end piston rod and the bracket surface of upper and lower air cylinders are hinged, and bracket can be
It is rotated counterclockwise under the drive of upper and lower air cylinders around fulcrum to horizontal position.
Existing plate shearing machine is all to use above-mentioned triangle material supporting rack structure, but when plate size is smaller mostly, due to adjacent
There is interval, it may appear that the phenomenon that material leakage, material leakage hits the retainer platform below material supporting rack, generates noise, and make between material supporting rack
Into the damage of plate and equipment；Simultaneously because above-mentioned two material supporting rack is articulated on a hinged seat welded with workbench,
The material supporting rack in this way under pneumatic linear actuator out of step conditions acts in agreement it is difficult to ensure that rising, thus can generate shadow to the flatness of plate
It rings, is reduced so as to cause shear precision and quality.
For another example, Chinese Patent Application No. is：201620727150.7, the applying date be on July 11st, 2016, innovation and creation name
Referred to as：The rear-mounted modularization material-supporting device of plate shearing machine, this application include material supporting rack, synchronizing shaft, feeding plate, cylinder and axle bed,
The axle bed is fixed on riser, and the synchronizing shaft is arranged on axle bed, and axis is provided between synchronizing shaft and axle bed
It holds；The material supporting rack is fixedly installed on by retainer fixed module on synchronizing shaft；The cylinder body end money of the cylinder be connected to
On the relatively-stationary channel steel of workbench, the tailpiece of the piston rod money of cylinder is connected on synchronizing shaft.Using this application material-supporting device by
The influence of panel length to be processed is still larger, the material-supporting device can not be used to carry out retainer when panel length is shorter, so as to nothing
Method ensures its machining accuracy, simultaneously because there are larger notch between material supporting rack and feeding plate, the plate generated so as to cause shearing
Material is easily inserted into above-mentioned notch, need to manually take out, troublesome in poeration.
In addition, during using existing pneumatic material retaining device, material supporting rack swing speed is difficult to control, easy when plate is not cut also
Occur due to material-supporting device declines sagging, be distorted deformation in knife-edge positions so as to cause plate, and then influence cutting for plate
Cut quality.
