Stamping molding die for automobile front beam tube

Abstract

The invention discloses a stamping molding die for an automobile front beam tube. The stamping molding die comprises an upper die base and a lower die base. An upper molding die assembly is arranged on the upper mold base. A lower molding die assembly is arranged on the lower die base. The two ends of the lower molding die assembly on the lower die base are each provided with a core rod assembly. The upper molding die assembly comprises upper end modules and an upper middle module, wherein the upper end modules are arranged at the two ends and can move up and down, and the upper middle module is fixedly arranged on the upper die base. Nitrogen springs are arranged between the upper end modules and the upper die base. The lower molding die assembly comprises a lower end module and a lower middle module, wherein the two ends of the lower end module are arranged on the lower die base, and the lower middle module is movably arranged in the lower die base and can be driven by an ejector rod of a stamping machine to move up and down. The motion stroke of the lower middle module is the distance between the axis of the molded middle section of a pipe and the axis of the pipe end section. Each core rod assembly comprises a core rod air cylinder arranged on the lower die base. The piston rod end of each core rod air cylinder is connected with a core rod. According to the stamping molding die, the automobile front beam tube can be stamped and molded at a time.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping forming die for an automobile front beam tube. Background technique [0002] The front beam tube structure of some cars such as figure 1 The shape shown is roughly trapezoidal. Since the distance between the axis of the middle section and the axis of the end section is relatively long after forming, direct stamping will cause serious deformation of the pipe. In traditional processing, it is first bent by a bending machine, and then stamped by a mold. This processing method requires longer man-hours and higher processing costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stamping mold which can press and form the front beam tube of the automobile at one time. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a stamping mold for the front b...
