Punching composite die for filter element end cover

Abstract

The invention relates to a punching composite die for a filter element end cover. The punching composite die comprises a guide column, an upper die base plate of a guide sleeve, a lower die base plate of the guide sleeve and a compositing device. The compositing device is mounted between the upper die base plate and the lower die base plate and comprises an upper die fixing plate, a punching male die fixing plate, a punching male die, a flanging male die, a guide pin, a pressing ring, a blanking female die fixing plate, a blanking female die, a flat-wire spiral spring, a guide post, a die shank, a lower die fixing plate, a punching female die, a punching female die fixing plate, a lower forming core, a punch-die, a circular wire spiral spring, a pressing plate, an ejector pin and an ejector plate. By the technical scheme, during a stroke of a punching machine, all punching procedures for forming the filter element end cover with a protrusion at the center, production efficiency can be increased, production cost can be lowered, and appearance quality and dimensional precision of products are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cold stamping dies, and in particular relates to a stamping compound die for a filter element end cover. Background technique [0002] At present, the filter element end cap in the filter industry usually adopts a single-process production method. For the production of the filter element end cap with a protrusion in the center, multiple stamping processes are required, such as: blanking, stretching, shaping, punching, trimming, For flanging, multiple single-process dies are used to process strips into products. Not only is the process cumbersome, increasing production costs and consumption of raw materials, but also affects the appearance quality and dimensional accuracy of products due to repeated positioning between stamping processes. Contents of the invention [0003] The purpose of the present invention is to provide a stamping composite mold for filter element end caps, aiming at the production of...
