Combination.
Fig. 1 is the composition structural representation of one embodiment of stamping die of the present invention, and Fig. 2 is decomposing schematic representation, reference picture
1, the stamping die includes mould internal cutting off material-strap structure, and mould internal cutting off material-strap structure includes：
Drift 1, the edge of a knife 2, ram block 4, screw 5, spring 6 and pull bar 7.
In the present invention, drift 1 is relative with the position of the edge of a knife 2, and ram block 4 is located at the side of drift 1, for adjusting drift
1 height.Material strip 3 is between drift 1 and the edge of a knife 2.When needing to cut off material strip 3, ram block 4 is pushed into dead point position
Put, make its padded drift 1, shorten the relative distance between drift 1 and the edge of a knife 2, the material strip 3 between drift 1 and the edge of a knife 2 can be
Upper and lower mould is punched cut-out, easy to operate, efficiency high during once closing.And when material strip 3 need not be cut off, will
Ram block 4 is extracted, and increases the relative distance between drift 1 and the edge of a knife 2, now the insufficient height of drift 1, even if upper and lower mould closes
Also material strip 3 will not be contacted, stamping die recovers normal production status.
In the present embodiment, drift 1 is arranged on mould, is upper die punch, and the edge of a knife 2 is arranged on lower mould, is lower die cutter mouth, drift
Cushion block 4 is located at the side of drift 1, can promote or extract from the top of drift 1.
Preferably, as shown in this embodiment, there is helical teeth 11 top of drift 1, and there are helical teeth 41, helical teeth 11 in the lower section of ram block 4
It is intermeshed therebetween with helical teeth 41 so that the resistance suffered when extracting with promoting above drift 1 of ram block 4 is smaller,
Convenient operation.
Preferably, there is sliding groove structure on the both sides of drift 1, and in the presence of ram block 4, drift 1 moves up and down along chute.
Preferably, as shown in this embodiment, ram block 4 is fixedly connected with pull bar 7, and the pull bar 7 stretches out punching press
Mould, positioned at facilitating manually-operated position.
In the present embodiment, groove 42 is offered on ram block 4, has screw 5 to be passed through from groove 42, is fixedly connected with drift 1,
And spring 6 is socketed with screw 5.When the spring is pressurized, elastic force jacks the screw and drives the upper die punch to move upwards,
Automatically reset to upper dead center position (spring is between drift upper surface and screw head lower surface).
