Abstract

The invention discloses an automobile top cover and a top cover rear cross beam nesting drawing forming method and die. According to the method, the top cover and a top cover rear cross beam forming cavity are nested in a drawing molding die, so that the top cover and the top cover rear cross beam are simultaneously formed in one stamping process. According to the method, the top cover and the topcover rear cross beam can be nested together to be produced, die toolings can be saved, and stamping production batches are reduced.

Description

technical field [0001] The invention belongs to the technical field of stamping processing systems for auto parts, and in particular relates to a nested drawing forming method and mold for an automobile roof and roof rear beams. Background technique [0002] In model development, the car roof and the roof rear beam are two parts, and two sets of mold tooling need to be developed, and two production lines are also required during production, or the same production line is produced in two batches. In this case, both mold tooling and production efficiency need to pay more costs. Contents of the invention [0003] The purpose of the present invention is to invent a molding process and a drawing die for the nested production of the roof and the rear beam of the automobile. The roof and the rear beam of the roof are nested together for production, which can save mold tooling and reduce stamping production batch. [0004] The invention discloses such a nested drawing forming me...
