End, spring 28 are arranged between bolt 27 and interlocking bar 23.When connecting rod is not contacted with pushing block 14, connecting rod is by spring 28
Push with 11 side wall of handle hole tight against.After pushing block 14 is driven by screw rod 13, and first jacking block 10 is ejected the first groove 9 simultaneously
Continue to advance to interlocking bar 23, the dome 24 on inclined-plane 25 and interlocking bar 23 on pushing block 14 cooperates, and allow dome 24 along
Inclined-plane 25 slides, so that interlocking bar 23 exits handle hole 11, so that the lower slot of the second groove 20 and originally and second is recessed
Corresponding second mating groove 26 of the lower slot of slot 20 misplaces, and the second jacking block 21 is finally exited the second groove 20, thus allow metal plate with
The separation of lower die holder 8 is more thorough.
The implementation principle of the present embodiment are as follows:
Interlocking bar 23 is by the effect of spring 28 tight against 11 side wall of handle hole, the first mating groove 18 and first under original state
The lower slot of groove 9 is corresponding, and the second mating groove 26 is corresponding with the lower slot of the second groove 20, and the first jacking block 10 is located at the first groove
In 9, the second jacking block 21 is located in the second groove 20, can be placed on metal plate on lower die holder 8 at this time, then operates the upper mold of press machine
7 decline of seat carries out punching operation to metal plate.
Be adjacent to after metal plate punching with lower die holder 8 and be difficult to remove, at this point, 13 one end operator of standing screw rod grip it is hand
Wheel 15 shakes, and makes the precession into handle hole 11 of screw rod 13, and then the first pushing block 14 is sliding along the length direction of handle hole 11
Dynamic, one end of the first jacking block 10 ejects the first mating groove 18 by pushing block 14, and the first jacking block 10 is driven to exit groove, and first
Jacking block 10 can enable metal plate one end on lower die holder 8 separate with lower die holder 8 during exiting the first groove 9, work as operator
When continuing to rotate hand-operated wheel 15 pushing block 14 being made to push interlocking bar 23 to spring 28, the second jacking block 21 is also ejected the second groove
20, to realize that the both ends of metal plate are separated with lower die holder 8.Therefore operator can be easily by the metal plate of completion of processing under
It is removed on die holder 8.
After metal plate is removed from lower die holder 8, shakes hand-operated wheel 15 and screw rod 13 is resetted, can continue to put on lower die holder 8
It sets metal plate and carries out punching operation.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
