Forming mould and stamping technology for n-shaped automobile cross beam

Abstract

The invention provides a forming mould and a stamping technology for an n-shaped automobile cross beam. The forming mould comprises an upper mould assembly and a lower mould assembly, wherein the upper mould assembly comprises an upper mould base body, an upper mould pressing side ring and an upper mould forming inserted block; a nitrogen gas spring for ejecting the upper mould pressing side ring and a working screw for preventing a self-mounted groove of the upper mould pressing side ring from falling are arranged between the upper mould pressing side ring and the upper mould base body; the lower mould assembly at least comprises a lower mould base body, a lower mould material support body, and a lower mould forming inserted block; a cover plate for preventing a self-mounted groove of the lower mould material support body from falling and a ejection rod mechanism for ejecting the lower mould material support body from the lower mould base body; a pressure machine provides an upward pressure source for the lower mould material support body. According to the invention, the design manufacturing technology of the traditional mould is changed, the mould design manufacturing technology is changed into 3-procedure mould, so that the mould design manufacturing cycle is shortened, and the mould design manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of stamping forming technology of automobile crossbeam and related dies, in particular to a forming die and stamping process of a several-shaped automobile crossbeam. Background technique [0002] Various sheet metal parts on automobiles are often produced on presses with automobile stamping dies. Specifically, there are generally several processes (several sets of molds) for the mold of each automobile sheet metal part. For example, the outer panel of a car door generally requires three sets of molds for drawing, trimming and punching, and flanging and side flanging, which are respectively installed on a press and produced by stamping. [0003] For another example, the double-row light truck--rear floor front beam, most of the traditional mold design and manufacturing processes are: blanking, drawing, trimming punching, trimming side trimming, punching side trimming, side flanging A total of 6 sequence mo...

AI Technical Summary

Problems solved by technology

The traditional process has the following disadvantages: many mold processes, low material utilization, long mold manufacturing cycle, and the waste of manpower caused by the large number of presses in the stamping production line, increased equipment loss, low production efficiency, and high production costs.
