Abstract

The utility model discloses a blanking deep drawing die. The blanking deep drawing die comprises an upper template and a lower template, wherein the upper template is fixedly provided with a die handle; the lower end of the upper template is fixedly provided with a female-male die fixing plate; the lower end of the female-male die fixing plate is fixedly provided with a blanking deep drawing male-female die; the upper end of the lower template is fixedly provided with a pad plate and a lower die fixing plate; the upper end of the lower die fixing plate is provided with a deep drawing male die and a blanking female die; and the deep drawing male die is matched with the die cavity of the blanking deep drawing male-female die, the die cavity of the blanking female die is matched with the blanking deep drawing male-female die. The blanking deep drawing die can simultaneously complete two procedures of drawing and blanking, shortens the machining time, improves stamping quality and obviously improves the machining efficiency of products.

Description

Blanking draws dark mould

Technical field

The utility model relates to blanking and draws dark mould.

Background technology

For the needs carrying roller cylinder 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 the one step completed mould of punching, side cut, shaping, 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 a kind of blanking and draws dark mould, can realize stretching, the completion of blanking twice instrument simultaneously, has shortened the time of processing, has improved the quality of punching press simultaneously, has obviously improved the working (machining) efficiency of product.

The technical scheme of the utility model is following:

Blanking draws dark mould, includes cope match-plate pattern, lower bolster, is installed with die shank on the cope match-plate pattern, and the lower end of cope match-plate pattern is installed with concavo-convex mould fixed head, and concavo-convex mould fixed head lower end is installed with blanking and draws dark punch-die; The upper end of lower bolster is installed with backing plate, counterdie fixed head; Counterdie fixed head upper end is equipped with draws dark punch, blanking die; Draw dark punch and match with the die cavity that blanking draws dark punch-die, the die cavity of blanking die draws dark punch-die with blanking and matches, and blanking draws dark punch-die and is provided with stripper outward; Be equipped with spring between stripper and the cope match-plate pattern; Knockout rod passes the top that die shank, concavo-convex mould fixed head extend into workpiece respectively, and the flange rest of workpiece has scraping wings, and the lower end of scraping wings is supported with charging ram.

Be installed with the guide fixed head on the sidewall of described counterdie fixed head, the upper end of guide fixed head is equipped with the guide bearing plate, and the roller that cooperates with the stripper laterally steering is installed on the guide bearing plate.

The two ends of described spring are set with on the spring holder that is fixed in cope match-plate pattern and stripper.

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.
