Abstract

The utility model discloses a blanking and drawing convex concave die of a blanking and drawing mould. The blanking and drawing convex concave die comprises a cylindrical convex concave die body, wherein the upper part of the convex concave die body is provided with a mounting hole; the mounting hole is matched with a convex concave die retaining plate; the lower part of the convex concave die body is provided with a concave die cavity; the concave die cavity is matched with a convex die; the outer edge of the lower end of the convex concave die body is provided with an edge; and the inner edge of the convex concave die body is provided with a round chamfer. According to the blanking and drawing convex concave die, two processes of drawing and blanking can be simultaneously realized; the processing time is shortened; meanwhile, the quality of punching is improved; and the processing efficiency of a product is obviously increased.

Description

The blanking that blanking draws dark mould draws dark punch-die
Technical field
The utility model relates to the blanking that blanking draws dark mould and draws dark punch-die.
Background technology
For the needs roller carrier shaft bearing workpiece with punching of cutting edge, generally need earlier part to be cut edge on bead cutter through three process; To its punching, be placed on shaping in the trimmer at last then, eliminate the influence that side cut and punching cause part; Can not only need three process like this, and need a lot of equipment, cause the production line length; Labour intensity is big, and productivity ratio is low high with production cost.In order to solve the problems of the technologies described above, the someone designs and once carries out blanking in the trimming, draws dark operation, but structural design is unreasonable, causes the working (machining) efficiency of part bad, and working (machining) efficiency is low.
The utility model content
The purpose of the utility model provides the blanking that a kind of blanking draws dark mould and draws dark punch-die, can realize simultaneously stretching, blanking twice instrument accomplishes, and shortened the time of processing, improved the quality of punching press simultaneously, obviously improved the working (machining) efficiency of product.
The technical scheme of the utility model is following:
The blanking that blanking draws dark mould draws dark punch-die; Include columniform convex-concave die body, convex-concave die body top has installing hole, and installing hole matches with the punch-die fixed head; The bottom of convex-concave die body has matrix cavity; Matrix cavity matches with punch, and the lower end outward flange of convex-concave die body is a blade, and convex-concave die body inward flange has rounded corner.
Described convex-concave die body upper surface has screwed hole.
The utility model be utilize blanking to draw dark punch-die and draw dark punch, blanking die cooperates simultaneously; Can realize stretching, the completion of blanking twice instrument simultaneously; Shorten the time of processing, improved the quality of punching press simultaneously, obviously improved the working (machining) efficiency of product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, the blanking that blanking draws dark mould draws dark punch-die, includes columniform convex-concave die body 1; Convex-concave die body 1 top has installing hole 2, and installing hole 2 matches with the punch-die fixed head, and the bottom of convex-concave die body has matrix cavity 3; Matrix cavity 3 matches with punch; The lower end outward flange of convex-concave die body is a blade 4, and convex-concave die body 1 inward flange has rounded corner 5, and convex-concave die body 5 upper surfaces have screwed hole 6.

Claims (2)

1. the blanking blanking that draws dark mould draws dark punch-die; Include columniform convex-concave die body, it is characterized in that: convex-concave die body top has installing hole, and installing hole matches with the punch-die fixed head; The bottom of convex-concave die body has matrix cavity; Matrix cavity matches with punch, and the lower end outward flange of convex-concave die body is a blade, and convex-concave die body inward flange has rounded corner.
2. the blanking that blanking according to claim 1 draws dark mould draws dark punch-die, it is characterized in that: described convex-concave die body upper surface has screwed hole.
