In order to guarantee the precision of product while pressing down product, blanking die also comprises patrix, and patrix comprises cope match-plate pattern, stripper and at least two second screws; Cope match-plate pattern and stripper offer the first spacing hole and the second spacing hole respectively, the center line of the first spacing hole and the second spacing hole coincides, punch is provided with between cope match-plate pattern and stripper, the top of punch is fixed by the first spacing hole and cope match-plate pattern, the bottom of punch and the second spacing hole matched in clearance;
The bottom of each second screw is fixedly connected with stripper, and the second screw top and cope match-plate pattern are slidably connected, and are undertaken spacing by head of screw; Each second screw is provided with return spring, and each return spring is between cope match-plate pattern and stripper.
In order to extend the service life of patrix, improve security performance, the number of the second screw is four, and rectangular setting; The top of cope match-plate pattern offers four the 3rd spacing holes; Head of screw on each second screw is slidably arranged in each 3rd spacing hole.
Conveniently operator is affectedly bashful, enhance production progress, and cope match-plate pattern is provided with die shank.
In order to carry out spacing to movable matrix, improve each precision of quality of product, the number of the first screw is four, and four the first screws are arranged side by side.
Conveniently keep in repair and change, holder is fixed by four the 3rd screws and base.
The invention has the beneficial effects as follows: the present invention can adopt the product of Sheet Metal Forming Technology to arc-shaped to complete stamping press; Have improvement cost low, improve the quality of products the beneficial effects such as precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples
The invention will be further described:
As Figure 1-Figure 2, a kind of blanking die, comprises patrix 1 and counterdie 2, and this counterdie 2 comprises the movable matrix 4 of base 3 and curved shape.
Base 3 is provided with holder 5, the first spacing perforation 6 that the bottom size that the side of holder 5 offers shape size and movable matrix 4 adapts.
The opposite side sidewall of holder 5 is provided with fixed head 7; Fixed head 7 is connected with holder 5 by the first screw 8.
In order to guarantee the precision of product while pressing down product, blanking die also comprises patrix 1, and patrix 1 comprises cope match-plate pattern 9, stripper 10 and at least two second screws 13; Cope match-plate pattern 9 and stripper 10 offer the first spacing hole 11 and the second spacing hole 12 respectively, the center line of the first spacing hole 11 and the second spacing hole 12 coincides, punch 101 is provided with between cope match-plate pattern 9 and stripper 10, the top of punch 101 is fixed by the first spacing hole 11 and cope match-plate pattern 9, the bottom of punch 101 and the second spacing hole 12 matched in clearance.
The bottom of each second screw 13 is fixedly connected with stripper 10, and the second screw 13 top and cope match-plate pattern 9 are slidably connected, and is undertaken spacing by head of screw 14; Each second screw 13 is provided with return spring 15, and each return spring 15 is between cope match-plate pattern 9 and stripper 10.
The number of described second screw 13 is four, and rectangular setting; The top of cope match-plate pattern 9 offers four the 3rd spacing holes 16; Head of screw 14 on each second screw 13 is slidably arranged in each described 3rd spacing hole 16.Above structure patrix 1 when operating has certain resiliency, can carry out spacing to the top of movable matrix simultaneously, thus not only increase precision, and effectively raise security when operating.
Conveniently operator is affectedly bashful, enhance production progress, cope match-plate pattern 9 is provided with die shank 17.
In order to carry out spacing to movable matrix 4, improve quality and the precision of product, the number of the first screw 8 is four, and four the first screws 8 are arranged side by side.Conveniently keep in repair and change, holder 5 is fixed with base 3 by four the 3rd screws 18.
In use, first the bottom on movable matrix 4 is positioned in the first spacing perforation 6, until the bottom on movable matrix 4 contacts with fixed head 7, by utilizing fixed head 7 to stop movable matrix 4 to continue to move forward, fixed head 7 pairs of movable matrixes 4 are made to play position-limiting action.
Subsequently workpiece 100 is placed on movable matrix 4, patrix 1 is placed in above movable matrix 4, utilize stripper 10 to push down workpiece 100, by forcing press, patrix 1 is slowly moved down subsequently.
Cope match-plate pattern 9 is along the second screw 13 slide downward, punch 101 moves down along with cope match-plate pattern 9 and moves, now stripper 10 pushes down the edge of workpiece 100, punch 101 by the middle part of workpiece 100 to punching press in movable matrix 4, after completing a punching press, remove patrix 1, cope match-plate pattern 9, by return spring 15 return, takes out movable matrix 4, takes out workpiece 100 simultaneously, movable matrix 4 is positioned in the first spacing perforation 6 more subsequently, just can carries out punching press next time.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
