Description

Technical Field

[0001] This invention relates to the field of stainless steel vehicle manufacturing and repair tooling technology, and in particular to a variable angle adjustment device for the door angle of stainless steel rail vehicles. Background Technology

[0002] Currently, in the manufacturing process of stainless steel rail and subway vehicles, the side wall steel structure adopts a beam-column structure, and the columns and wall panels are all made of stainless steel thin plates. The doorway area has a large opening, and in order to ensure the strength of the doorway area, it is necessary to reinforce the doorway area. After welding the door corner area and the reinforcing plate on the inside of the doorway, the doorway area has large welding deformation, resulting in wavy outward deformation, which affects the flatness of the outer surface, the installation of the unlocking device in the assembly process, and the vehicle clearance.

[0003] The existing processing technology uses a combination of flame adjustment and hammering. After adjustment, the flatness of the outer surface of the wall panel meets the flatness requirements of the steel structure technical conditions, but the appearance quality is poor. The original large protrusions have become dense dot-like protrusions. At the same time, the stainless steel exhibits overheating and blackening after flame adjustment. Even after passivation and blackening removal treatment, color differences still exist, which seriously affects the appearance quality.

[0004] Due to the strength requirements of the vehicle body steel structure, structural improvements and adjustments cannot be made. Flame treatment and hammering cause dense protrusions and color changes on the stainless steel surface. The dense protrusions also affect the sealing of the door unlocking device and other installations, affecting product quality and production efficiency. Summary of the Invention
