Abstract

The invention discloses a bent compound die which comprises an upper die holder, a left convex die, a right convex die, a pressure plate, a concave die and an ejection block, wherein the left convex die and the right convex die are symmetrically and fixedly arranged on the upper die holder, the pressure plate is arranged between the left convex die and the right convex die and movably arranged on the upper die holder, and an elastomer 1 is arranged between the pressure plate and the upper die holder; and the concave die is provided with a narrow-mouth cavity, the bottom of the narrow-mouth cavity is provided with a blind hole, the ejection block is movably arranged in the blind hole, and an elastomer 2 is arranged between the ejection block and the bottom of the blind hole. The die disclosed by the invention can realize the one-time forming of flanging U-shaped bending, and is simple in structure, low in production costs, easy to maintain and long in service life, therefore, the die can reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of cold stamping processing, in particular to a bending composite die. Background technique [0002] The U-shaped bending structure of the flanging usually requires two forming processes: the first U-shaped forming, and the second flanging forming. In the prior art, many U-shaped bending composite molds for once-formed flanging are also disclosed, but these composite molds have complex structures, high manufacturing costs, inconvenient maintenance, and short service life, so the production costs are relatively high. It is further improved to provide a mold with a simpler structure to realize one-time forming of the U-shaped bending of the flanging. Contents of the invention [0003] The purpose of the present invention is to provide a bending composite mold, which can realize the one-time forming of the U-shaped bending of the flanging, and has a simple structure, low manufacturing cost, easy maintenance,...
