Abstract

The invention provides punching forming equipment. The punching forming equipment comprises a lower die assembly and an upper die assembly which are oppositely arranged; the lower die assembly comprises a lower die base and a female die arranged above the lower die base; a groove and a blanking hole which is located below the groove and communicates with the groove are formed in the female die ina concave mode; the upper die assembly comprises an upper die base and a punching unit installed below the upper die base; the punching unit comprises a punching sleeve and a punching needle; a vertically-through accommodating cavity is formed in the center of the punching sleeve; a concave punching part is arranged on the periphery of the lower end of the punching sleeve; the section outline of the punching part is in an arc shape; the punching sleeve is opposite to the groove and performs punching through the punching part; the punching needle is accommodated in the accommodating cavity; thelower end of the punching needle extends downwards out of the accommodating cavity, is opposite to the blanking hole and is used for pre-punching; and the punching needle and the punching sleeve perform pre-punching and punching forming on a plate placed on the female die along with descending of the upper die base. By means of the combined punch unit, pre-punching and convex-punching forming canbe completed at a time, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stamping and forming dies, in particular to a punching and forming equipment. Background technique [0002] In the vehicle manufacturing industry, the processing of holes on some auto parts, such as the anti-skid holes of automobile bumpers, is generally formed by stamping. At present, the forming method of the anti-skid hole is divided into two processes: pre-punching and punching, that is to say, two sets of dies need to be used for punching. First, a set of dies is used to punch the pre-punching on the sheet, and a pre-punching hole for positioning is punched on the sheet; then, another set of dies is used to punch the semi-finished sheet, and finally a non-slip hole is formed. Since the above punching method needs to be punched twice, the production efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a punching and forming equipment to solve the ...
