Problems solved by technology

The above-mentioned forming process generally requires two processes of internal pressure and stamping, especially the subsequent stamping is internal high pressure forming, which needs to maintain a pressure of at least 200MPa, which requires high equipment, and the whole process requires preforming molds and internal high pressure. There are two sets of molds for forming molds, resulting in the disadvantages of complex process and high cost

Abstract

A forming method for an automobile torsion beam is characterized by including the preparation steps that firstly, a forming mold is opened to a certain height, and a pipe blank is arranged in the mold; secondly, liquid is injected in the pipe blank so that the interior of the pipe blank can be filled with the liquid; thirdly, pressurization and mold assembly are conducted in the pipe blank, and in the mold assembly process, the liquid filling pressure is regulated and controlled through a pressure control system; and fourthly, a torsion beam finished product is formed by the pipe blank under the dual effect of internal liquid supporting and an external mold cavity, and then mold opening and piece taking are conducted. The forming method has the beneficial effects that no preforming molds are needed, pressure being 200 MPa or above is not needed either, and the process is simple.

Description

technical field [0001] The invention relates to the technical field of automobile torsion beams, in particular to a forming method of automobile torsion beams. Background technique [0002] The torsion beam is an important part of the rear axle. The forming method of the torsion beam is generally the internal high-pressure forming process: tube making: through the tube making equipment, the high-strength steel plate is bent into a round tube of the required size, and then it is processed by a high-frequency welding machine. Welding to obtain a round tube with a closed section; preforming: by placing the tube in a cold forming mold and then cold stamping to obtain a semi-finished part with a rough shape; internal high pressure forming: placing the semi-finished part in an internal high pressure In the forming mold, the final shape of the part is obtained by filling the inside and outside of the pipe, pressurizing, and forming. The above-mentioned forming process generally re...
