Process for producing modular sleeper beam for railway carriage

Abstract

The invention discloses a process for producing a modular sleeper beam for a railway carriage, which comprises the following steps of: welding a lower cover plate of the sleeper beam, a web plate, an inner clapboard and an air seat into a whole; welding anti-snake movement damper mounting beams at left and right ends of the sleeper beam; welding first and second transverse beams behind the sleeper between the anti-snake movement damper mounting beams on the rear of the sleeper beam; turning the sleeper beam, and welding an air spring base plate, a center plate mounting base plate and a vertical damper seat on the lower cover plate of the sleeper beam; and conveying a sleeper beam module to a ,machining center, and machining an air spring mounting surface, a center plate mounting surface and an anti-snake movement damper mounting surface. The sleeper beam, the first and second transverse beams behind the sleeper and the anti-snake movement damper mounting beams are welded to form an integral module, the integration degree is high, and the production efficiency is improved. After the whole module is subjected to assembly welding, the air spring mounting surface on the lower cover plate of the sleeper beam, the center plate mounting surface and the anti-snake movement damper mounting surface are subjected to unified machining and molding in the sleeper beam machining center; therefore, the machining accuracy of various mounting surfaces is guaranteed.

Description

technical field [0001] The invention relates to a railway passenger car corbel module structure, which belongs to the technical field of railway passenger car underframe structures. Background technique [0002] At present, the steel structure of the underframe of railway passenger cars in my country generally adopts a structure without a center sill. The corbel module only includes the corbel part, which does not form a whole with the rear longitudinal beam of the bolster and the anti-snake shock absorber installation beam. The shape and position tolerance requirements of the surface relative to the lower cover of the corbel are relatively high, so the requirements for the general assembly and welding of the chassis are relatively high. At the same time, due to the existence of the longitudinal beam in the middle position of the vehicle behind the sleeper, when the coupler force is transmitted to the sleeper beam along the traction beam, it cannot be smoothly transmitted to ...
