Reset spring 71 on 73 generates pressure distortion, and for the withstanding tight block 75 of 73 end of catch bar by 20 Level Promoting of baffle, baffle 20 is logical
The protruding block 20a for crossing bottom is moved in guiding groove 76, and the baffle pressure spring 21 for being mounted on 20 side of baffle generates pressure distortion,
Two groups of pushing components 7 in cavity plate sliding slot 8a are set under the driving of guiding skewback 12, opposite direction is mobile to being mounted on baffle 20
On plate 19 carry out positioning and locking, prevent plate 19 from shifting or moving phenomenon, when the guiding skewback 12 is depressed into most
When big stroke, two baffles 20 and the gap size of the two sides of the plate 19 are ignored, and prevent plate 19 by baffle
20 are squeezed and deformed.
In the present embodiment, refering to attached drawing 4, the baffle 20 is L shape, the bending part of the upper end of the baffle 20 with
Plate 19 is clamped, and the bottom end of the baffle 20 in guiding groove 76, is set as the gear of L shape by 21 sliding plug of protruding block
Plate 20, not only can more plates carry out positioning and lockings, while plate can also be clamped, discharging after preventing punching pin from punching hole
When plate takeoff phenomenon, influence the service life of mold；The cooperation of the protruding block 21 and guiding groove 76 of bottom end is set,
Anti- baffle plate 20 run-off the straight phenomenon when cavity plate sliding slot 8a is slided.
Working principle of the present invention, plate 19 are placed on cavity plate 8, and upper die holder 1 moves downward, and stripper 5 is driven to transport downwards
Dynamic, the guiding skewback 12 on stripper 5 is plugged in cavity plate sliding slot 8a, by pushing skewback 71 to pass through latch segment 75 for baffle 20
It pushes, baffle 20 contacts with the side of plate 19, and with being oriented to moving down for skewback 12,19 liang of side baffles 20 of plate are by plate
The brute spring 4 of positioning and locking, 5 upper surface of stripper compresses plate, the punching pin shield being mounted in guide groove 5a
Set 6 is first contacted with plate 19, the moving downward with punch-pin fixing sleeve 16 of push spring 18 connecting with 6 upper end of punching pin sheath,
Strong pressure will be generated, so that pressure of the plate 10 to be subject to around punching further increases, punch retainer 3 drives punch-pin to fix
Piercing punch 17 in set 16 moves downward, and punching pin 17b is punched out operation to plate, and the waste material swept away is fallen from charging conduit 11
Under, herein after the completion of punching, 1 return of upper die holder, stripper 5 is moved upwards with action-oriented skewback 12, and skewback 71 is pushed to reset
Return under the active force of spring 72, baffle 20 are slided along guiding groove 76 is horizontal, are replied under the active force of baffle pressure spring 21
To origin-location, plate 19 is mobile next to punching position, repeats above-mentioned working principle and is punched out operation.
In conclusion the beneficial effect of this hair, the present invention obtains piercing punch and is set as two parts, the T font formed punch of upper end
It is mounted on punch retainer by punch-pin fixing sleeve, punching pin a part of lower end is located in punch-pin fixing sleeve, punch-pin fixing sleeve
Not only guiding role can be played to piercing punch, reduce the resistance being subject to when the punching of piercing punch, prevent punching pin from occurring curved
Bent breakage phenomenon, while punch-pin fixing sleeve bottom end connects punching pin sheath by external push spring, punching pin sheath is plugged on guiding
In slot, and the end of punching pin is located in punching pin sheath, and punching pin sheath can be further improved the punching pin that is protected to punching pin
Bending phenomenon occurs for end, and because the bottom diameter of punching pin sheath is smaller, the contact area with plate is further decreased, push
The pressure of spring is transmitted on material, is formed the pressure for needing to be subject to around punching on plate and is further increased, prevents punching pin
It shifts, so that the precision of punching is more accurate, while the baffle being arranged in cavity plate sliding slot can be to plate by thrust assemblies
Material carries out positioning clamping action, prevents when punching operation plate to shift or walk about phenomenon, reduces punching pin in punching operation
Cross force, reduce punching pin and occur bending and deformation phenomenon, extend the service life of piercing punch, improve work efficiency；Setting
For the baffle of shape, not only can more plates carry out positioning and lockings, while plate can also be clamped, prevent punching pin from punching
Plate takeoffs phenomenon when discharging behind hole, influences the service life of mold；The protruding block of bottom end is set and is oriented to groove
Cooperation, anti-baffle plate run-off the straight phenomenon when cavity plate sliding slot slides.
The foregoing is merely the schematical specific embodiments of the present invention, before not departing from conceptions and principles of the invention
It puts, the equivalent changes and modifications that any those skilled in the art is made should belong to the scope of protection of the invention.
