Auxiliary sweeping board manufacturing process, auxiliary frame manufacturing process, and auxiliary frame

Abstract

The invention relates to an auxiliary sweeping board manufacturing process, an auxiliary frame manufacturing process, and an auxiliary frame. In the manufacturing process, side edges of boards are processed according to corresponding flanging outlines on an auxiliary frame, so that an auxiliary frame outline formed by follow-up stamping is ensured to meet the actual product appearance requirement;secondly, the multiple boards are welded, so that a weld pass is formed between each two adjacent boards, and boards to be stamped are formed; then, the boards to be stamped are placed into corresponding stamping dies so as to be stamped, so that auxiliary sweeping boards are formed; and finally, the two auxiliary sweeping boards are fastened mutually so as to be welded, so that the manufacturingof the auxiliary frame is completed. According to the manufacturing processes, a way of welding firstly and stamping secondly is adopted, so that the occurrence of the phenomenon that the auxiliary sweeping boards formed by stamping are heated so as to be deformed due to welding is effectively avoided, and the planeness of the auxiliary sweeping boards is favorably improved. Meanwhile, the stamping step is set after the welding step, so that the stamping process has a certain shaping function on the welded planes, the welding deformation of the boards to be stamped is reduced, and the overallplaneness of the auxiliary frame is further improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a manufacturing process of an auxiliary vehicle plate, a manufacturing process of an auxiliary vehicle frame and the auxiliary vehicle frame. Background technique [0002] The sub-frame, also known as the sub-frame, is an important skeleton part of the car body, mainly supporting the front and rear axles and connecting them with the "main frame". The subframe is often used to fix modules such as control arms, stabilizer bars, power steering, and engine mounts. Therefore, the process has high requirements for the stiffness and manufacturing accuracy of the subframe. [0003] The traditional sub-frame manufacturing process usually adopts stamping first and then welding process, and each section of steel plate is pre-stamped and formed; after forming, they are welded separately to form the upper and lower plates; finally, the upper and lower plates are assembled and welded to compl...

AI Technical Summary

Problems solved by technology

However, this manufacturing method can easily lead to welding heating and deformation of the upper and lower plates, and the key dimensions cannot be controlled, which affects the assembly accuracy of the upper and lower plates, resulting in a serious reduction in the manufacturing accuracy of the entire product
