Problems solved by technology

[0002] At present, many products use circular arcs and positioning holes. The size of circular arcs and positioning holes has position requirements, which are consistent with the matching parts. Since the processes of circular arcs and positioning holes of left and right symmetrical parts are carried out separately, circular arcs are used The milling is processed, and the positioning hole is drilled. With this production method, the consistency of the parts is poor, and the dimensional accuracy cannot meet the technical requirements. Even if it is processed, it cannot be matched with the matching parts. Welding has affected, material waste is large, production efficiency is low, and production cost is high

Abstract

A punching compound ide comprises an upper die portion and a lower die portion. The upper die portion comprises a die shank, an upper die seat, an upper die baseplate, two upper top blocks, a rubber cushion block, an upper press block and two guide sleeves. The die shank is positioned above the upper die seat, and the upper die baseplate is positioned below the upper die seat. The upper top blocks are positioned below the upper die baseplate, and are mounted on the left portion and the right portion of the upper die baseplate through hexagon socket head bolts and dowels respectively. The rubber cushion block is positioned below the middle of the upper die baseplate. The upper press block is positioned below the middle of the rubber cushion block, and penetrates into the upper die baseplate from the upper die seat in a threaded mode to be connected with the rubber cushion block and the upper press block. The guide sleeves are positioned at two positions in front of the lower side of the upper die seat, and are mounted below the upper die seat in a close-fitting mode. By the punching compound die, shearing of workpieces with different materials, arcs and bore diameters can be realized.

Description

technical field [0001] The invention relates to a cold stamping die in the field of mechanical processing, in particular to a punching composite die. Background technique [0002] At present, many products use circular arcs and positioning holes. The size of circular arcs and positioning holes has position requirements, which are consistent with the matching parts. Since the processes of circular arcs and positioning holes of left and right symmetrical parts are carried out separately, circular arcs are used The milling is processed, and the positioning hole is drilled. With this production method, the consistency of the parts is poor, and the dimensional accuracy cannot meet the technical requirements. Even if it is processed, it cannot be matched with the matching parts. Welding has caused impact, material waste is large, production efficiency is low, and production cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the ...
