Problems solved by technology

[0003] The orthopedics of welded parts is the biggest waste in the production process of welded products, which increases the manufacturing cycle of welded products. In the past, the repair time of each group of frames was about 3 hours (two people). According to the production capacity plan of 12 vehicles / day, every day is wasted 72 hours; and due to mechanical and flame adjustments, the base metal of the welded product will collapse, the risk of weld cracks and tissue hardening will affect the safety of the product

Abstract

The invention relates to the technical field of welding deformation control, and discloses a frame welding deformation control method and a frame welding tool. The method includes performing structural simulation analysis on the frame, so as to divide the frame into several welding components according to modules, and determine the welding sequence of the weld seams between each of the welding components; based on the welding sequence, complete each of the welding Welding of welds between components. The frame welding tool includes a clamp body and a middle support, an anti-twist device, a beam pressing device and a side beam pressing device all arranged on the clamp body, so as to facilitate the installation and fixing of the frame. The invention can realize the maintenance-free structure, greatly shorten the manufacturing cycle, and improve the efficiency and quality.

Description

technical field [0001] The invention relates to the technical field of welding deformation control, in particular to a frame welding deformation control method and a frame welding tool. Background technique [0002] Due to the uneven heating and cooling of the welding process, the welding structure inevitably has welding deformation. The welding deformation usually needs to be rectified by machinery, flame, or a combination of the two to obtain a qualified size. [0003] Orthopedics of welded parts is the biggest waste in the production process of welded products, which increases the manufacturing cycle of welded products. In the past, the adjustment time for each set of frames was about 3 hours (two people). According to the production capacity plan of 12 vehicles / day, waste is lost every day. 72 hours; and due to mechanical and flame adjustment, the base metal of the welded product collapses, the weld cracks and the risk of tissue hardening, which affects the safety of the...
