Embodiment 1

[0019] The manufacturing method of the automobile "S" type longitudinal beam of the present embodiment comprises the following steps:

[0020] A: Blanking: punch out the required "S"-shaped outer contour blank from the sheet;

[0021] B: drawing: the blank is punched and extruded into the die to form a longitudinal beam;

[0022] C: Trimming for the first time: remove the overflow or burr on the edge of the longitudinal beam. It is required that the scrap knife does not interfere, and the scrap can slide down freely without jamming; no large burrs and sags will appear in the trimming of the part. defect;

[0023] D: Flanging: Flanging is performed on the edge of the predetermined part of the longitudinal beam;

[0024] E: Shaping: Shaping the main plane and side walls of the longitudinal beam parts;

[0025] F: The second trimming: remove the overflow or burr on the side wall of the longitudinal beam;

[0026] G: Punching: Punch out a through hole with a predetermined posi...

Abstract

The invention aims to provide a method for manufacturing an S-shaped longitudinal beam of an automobile. The method is used for solving the problems of torsion, bouncing, warping and the like of the S-shaped longitudinal beam and improving the yield of a single piece and the loading accuracy. The method for manufacturing the S-shaped longitudinal beam of the automobile comprises the steps of (A) blanking, (B) drawing, (C) first-time trimming, (D) flanging, (E) reshaping, (F) second-time trimming, and (G) punching. The method for manufacturing the S-shaped longitudinal beam of the automobile has the advantages that by the repeated reshaping and trimming processes, the problems of torsion, bouncing, warping and the like of the S-shaped longitudinal beam are solved, and the problems of cracking, micro-cracking and the like of flanges caused by different directions of burrs are avoided. The punching process is carried out finally, the problems of warping, torsion, bouncing and the like are solved before the final punching process, and the problems of low hole position accuracy, hole deformation and the like caused by punching prior to reshaping are avoided, so that the yield of the single piece and the loading accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a method for manufacturing an "S"-shaped longitudinal beam of an automobile. Background technique [0002] Different cars have different side member structures. Due to its special structure, the "S"-shaped longitudinal beam has an "S"-shaped structure as a whole, which is prone to twisting, rebounding, and warping. Problems such as twisting, tilting, and rebounding occur, and changing the structure of the longitudinal beam will affect the structure of the vehicle and consume a lot of manpower and material resources. Therefore, improving the stamping method of the "S"-shaped longitudinal beam is of great significance to the improvement of the qualification rate of the longitudinal beam and the improvement of the loading accuracy. Contents of the invention [0003] The object of the present invention is to propose a method for manufacturing an "S"-s...
