Description
Technical field
The invention belongs to plate shearing machine technical field, more specifically to a kind of pneumatic retainer machine of high-precision plate shearing machine
Structure and rear retainer atmospheric control and retainer method.
Background technology
In machinery manufacturing industry, plate shearing machine is a kind of conventional process equipment, is mainly used under the shearing of sheet material workpiece
Material, there is the characteristics of easy to operate, operating efficiency is high, plate shearing machine is widely used to common mechanical manufacture, automobile, container system
Make, the cutting member processing of the industry such as device for switching and light industry.Although the plate shearing machine species 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
Motion, so as to drive cutter 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 generally set, but when shearing plate is wider, due to rear plate
Deadweight and it is sagging, it is sagging after plate can not contact striker plate, now back material stopping cannot play a role or its positioning accurate
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 wasted time and energy using setting-out shearing, inefficiencies.For problem above, a variety of retainers are had been developed that in the prior art
Mode, it is most of to use pneumatic material retaining device, but the complex structural designs of existing material-supporting device, processing is cumbersome, cost is high, and
Retainer distance is big, and flitch lid of lying during blanking does 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 case include frame, and the frame is provided with lubricating substance
Plate, the side of frame are provided with fulcrum, and the fulcrum is provided with the bracket of two parallel triangles, upper and lower gas is provided with below bracket

Into the damage of plate and equipment；Simultaneously because above-mentioned two material supporting rack is articulated with a hinged seat with workbench welding,
The material supporting rack so under pneumatic linear actuator out of step conditions acts in agreement it is difficult to ensure that rising, thus can produce shadow to the flatness of plate
Ring, so as to cause shear precision and quality to reduce.
And for example, Chinese Patent Application No. is：201620727150.7, the applying date is on July 11st, 2016, innovation and creation name
Referred to as：The rear-mounted modularization material-supporting device of plate shearing machine, this application case include material supporting rack, synchronizing shaft, feeding plate, cylinder and axle bed,
Described axle bed is fixedly installed on riser, and described synchronizing shaft is arranged on axle bed, and axle is provided between synchronizing shaft and axle bed
Hold；Described material supporting rack is fixedly installed on synchronizing shaft by retainer stuck-module；The cylinder body end money of described cylinder be connected to
On the relatively-stationary channel-section steel of workbench, the tailpiece of the piston rod money of cylinder is connected on synchronizing shaft.Using this application case 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 larger breach between material supporting rack and feeding plate be present, so as to cause to shear caused plate
Material is easily inserted into above-mentioned breach, 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 sagging because material-supporting device declines, so as to cause plate to be distorted deformation in knife-edge positions, and then influence plate is cut
Cut quality.
