Abstract
The invention discloses a kind of built-in air-cylinder type discharging structure, including：The cylinder being machined in inside punch-pin；Coordinate the piston rod of installation with the cylinder；The recess of punch-pin outer surface is arranged at, which is provided with the cylinder exhaust port connected with cylinder；The fixed plate of cylinder periphery is installed on, which is provided with the punch retention hole for coordinating installation with cylinder；Setting cylinder air inlet is got through in the backing plate being installed on above fixed plate, the backing plate side, and cylinder air inlet, punch retention hole, recess, cylinder exhaust port form the gas flow for flowing through cylinder.The present invention utilizes cylinder principle, cylinder is directly processed in punch-pin, depending on cylinder diameter size is with punch-pin shape, size designs suitable dimension according to the requirement of stripping force, mix matching piston rod, solve the problems, such as in mould it is compact-sized without redundant space installation cylinder, reduce material strip or deformation of products during bar stock cutting by punching, it is punched dimensionally stable, good product quality.
Description
Technical field
The invention belongs to mould applications, more particularly to a kind of built-in air-cylinder type discharging structure.
Background technology
The discharge way of conventional ones mould product and material strip is more using the structure of spring+mandril or stripper, this knot
Structure is simply also practical, but the punching press to ultra-thin materials is improper, because mandril or stripper are the precompression dischargings by spring, it is necessary to
Punch-pin sword top surface is protruded, the height of protrusion depends on the height of demand de- material.When punching is not completed, the precompression of spring is just
It can be delivered to by mandril or stripper on material strip or product, material strip or product are caused to deform, the size of punching is unstable, very
The effect that material strip or product do not have de- material can be also destroyed to mandril.If being used as secondary power by cylinder, completed in punching
Into carry out again discharging be also can be with, it is but usually compact-sized in mould, cylinder is installed without unnecessary space.
The content of the invention
In view of the problems of the existing technology, the present invention provides a kind of built-in air-cylinder type discharging structure.
The present invention is achieved in that a kind of built-in air-cylinder type discharging structure includes：
The cylinder being machined in inside punch-pin；
Coordinate the piston rod of installation with the cylinder；
The recess of punch-pin outer surface is arranged at, which is provided with the cylinder exhaust port connected with cylinder；
The fixed plate of cylinder periphery is installed on, which is provided with the punch retention hole for coordinating installation with cylinder；
Setting cylinder air inlet is got through in the backing plate being installed on above fixed plate, the backing plate side, and cylinder air inlet, punch-pin are fixed
Hole, recess, cylinder exhaust port form the gas flow for flowing through cylinder.
Further, the cylinder exhaust port is arranged at recess lower part.
Further, the built-in air-cylinder type discharging structure is further included coordinates unloading for installation positioned at male bottom with the punch-pin
Flitch and the cavity plate and die holder for being installed on the stripper bottom.
The present invention utilizes cylinder principle, cylinder is directly processed in punch-pin, depending on cylinder diameter size is with punch-pin shape, size is pressed
Requirement according to stripping force designs suitable dimension, mixes matching piston rod, it is compact-sized not unnecessary in mould to solve
The problem of cylinder, is installed in space, reduces material strip or deformation of products during bar stock cutting by punching, is punched dimensionally stable, product quality
It is good.

Gas port 5 is arranged at 12 lower part of recess；
The fixed plate 8 of the periphery of cylinder 7 is installed on, which is provided with the punch retention hole 9 for coordinating installation with cylinder 7；
The backing plate 11 of the top of fixed plate 8 is installed on, which, which gets through, sets cylinder air inlet 10, cylinder air inlet 10,
Punch retention hole 9, recess 12, cylinder exhaust port 5 form the gas flow for flowing through cylinder 7, to realize the action of cylinder；
Further include and coordinate the stripper 3 of installation with the punch-pin 6 positioned at 6 bottom of punch-pin and be installed on the recessed of 3 bottom of stripper
Mould 2 and die holder 1.
The present invention utilizes cylinder principle, cylinder 7 is directly processed in punch-pin 6, depending on cylinder diameter size is with 6 shape of punch-pin, greatly
The small requirement according to stripping force designs suitable dimension, mixes matching piston rod 4, and solving compact-sized in mould does not have
Redundant space installs the problem of cylinder, reduces material strip or deformation of products during bar stock cutting by punching, is punched dimensionally stable, product matter
Measure.
The above is only the preferred embodiments of the present invention, and not makees limitation in any form to the present invention,
Every technical spirit according to the present invention belongs to any simple modification made for any of the above embodiments, equivalent variations and modification
In the range of technical solution of the present invention.
