Abstract
A kind of blank body,Belong to punching machine technical field,It includes push rod,Guider,Parallelogram linkage,Cylinder,Support frame,Air compressor,Gas receiver,The artis diagonal up and down of parallelogram linkage is hinged with the bottom of push rod and the top movable ground of support frame respectively,In the other left and right of parallelogram linkage, diagonal artis is actively hinged with the piston rod part of cylinder and the bottom of cylinder respectively,The piston-rodless inner chamber of described cylinder has steam vent,The steam vent is directly communicated with air,The piston rod cavity that has of cylinder is connected by high-pressure air pipe with the inside of gas receiver,The gas outlet of air compressor is connected with the inside of gas receiver,Pressure-pad-force of the invention can gradually be reduced with the increase of amount of tension,So,Be conducive to stretching the carrying out of operation,And there is improve product quality.
Description
Technical field
The present invention relates to punching machine, and in particular to the blank body of punching machine, belong to punching machine technology
Field.
Background technology
At present, punching machine workbench bottom, blank body is generally set, existing blank body is usually
Single-acting formula cylinder, although this kind of blank body has the advantages that simple structure, due to during flanging, with
The compression stroke of piston cylinder is reduced, and the air pressure in piston cylinder also sharp rises, so, this will cause pressure-pad-force drastically
Rise, and in the stretching operation of forcing press, with the raising of stretching depth, it is desirable to which pressure-pad-force is gradually reduced, could preferably
Ensure the quality of product, so, existing blank body is unfavorable for improving the quality of product.
The content of the invention
It is an object of the invention to：For existing forcing press blank body existing for：Pressure-pad-force cannot be realized with drawing
The increase of the amount of stretching and gradually reduce, be thus unfavorable for stretching operation and easily cause the defect of product quality, the present invention is provided
A kind of new blank body, this kind of pressure-pad-force of blank body can gradually be reduced with the increase of amount of tension, be conducive to
The carrying out of operation is stretched, and there is improve product quality.
The present invention realizes that the technical scheme that above-mentioned purpose is used is：A kind of described blank body, it includes push rod
（1）, guider（2）, parallelogram linkage（3）, cylinder（4）, support frame（5）, air compressor（6）, gas receiver
（7）, described parallelogram linkage（3）Artis diagonal up and down respectively with push rod（1）Bottom and support frame
（5）Top movable ground hinged, push rod（1）It is arranged on guider（2）On, two kinds have the freedom mutually slided
Degree, in the other left and right of parallelogram linkage diagonal artis respectively with cylinder（4）Piston rod part and gas
Cylinder（4）Actively hinged, the described cylinder in bottom（4）Piston-rodless inner chamber there is steam vent（8）, the steam vent
（8）Directly communicated with air, cylinder（4）Have piston rod cavity pass through high-pressure air pipe and gas receiver（7）Inside be connected, it is empty
Air compressor（6）Gas outlet and gas receiver（7）Inside be connected.
Operation principle of the invention is：If making push rod（1）Active force be F；The active force of piston rod is P；Left and right two
Angle between connecting rod is a；Can then release：F=P*ctg（a）；Because compressed air is substantially steady state value, so, the value of P
Also substantial constant, and when amount of tension gradually increases, a contend it is cumulative big, so, trigonometric function ctg（a）Also gradually decrease,
So, F numerical value is also progressively decreased.
Beneficial effect：Be can be seen that because pressure-pad-force of the invention can be with amount of tension by operation principle of the invention
Increase and gradually reduce, so, be conducive to stretching the carrying out of operation, and there is improve product quality.
Brief description of the drawings
Accompanying drawing 1 is principle schematic of the invention.
Shown in figure：1 be push rod, 2 be guider, 3 be parallelogram linkage, 4 be cylinder, 5 be support frame,
6 it is air compressor, 7 is gas receiver.
Specific embodiment
With reference to accompanying drawing, specific embodiment of the invention is：
A kind of described blank body, it includes push rod（1）, guider（2）, parallelogram linkage（3）, cylinder
（4）, support frame（5）, air compressor（6）, gas receiver（7）, described parallelogram linkage（3）Diagonal up and down close
Node respectively with push rod（1）Bottom and support frame（5）Top movable ground it is hinged, in parallelogram connection-rod machine
The diagonal artis in the other left and right of structure respectively with cylinder（4）Piston rod part and cylinder（4）Bottom be actively hinged
Together, described cylinder（4）Piston-rodless inner chamber there is steam vent（8）, the steam vent（8）Directly communicated with air, gas
Cylinder（4）Have piston rod cavity pass through high-pressure air pipe and gas receiver（7）Inside be connected, air compressor（6）Gas outlet
With gas receiver（7）Inside be connected.
Claims (2)
1. a kind of blank body, it includes push rod（1）, guider（2）, parallelogram linkage（3）, cylinder（4）, branch
Support（5）, air compressor（6）, gas receiver（7）, described parallelogram linkage（3）Artis diagonal up and down point
Not and push rod（1）Bottom and support frame（5）Top movable ground it is hinged, it is characterised in that：In parallelogram
