Abstract

The invention relates to a wagon arc side wall assembly production process. The wagon arc side wall assembly comprises a first side wall plate, a second side wall plate and a third side wall plate which are cambered and welded successively from the top to the bottom. An upper side beam assembly is welded and fixed on a top end plate wall of the first side wall plate. A side wall stiffening beam assembly is welded and fixed longitudinally at the first side wall plate and second side wall plate side wall welding position. A lower side beam assembly is welded and fixed longitudinally at the second side wall plate and third side wall plate welding position. A lower side beam reinforcing beam assembly is welded and fixed longitudinally below the lower side beam assembly. According to the production process, by the side wall plate longitudinal splicing design mode and different-thickness design, spliced welded joints are hidden, the spliced welded joint length is reduced effectively, the joint groove machining amount and the welding material consumption are reduced, the production efficiency is improved, and costs are saved; the side wall flatness is controlled effectively, and the appearance is attractive; the process is simplified, the production difficulty and the labor intensity are reduced, the tooling equipment investment is simple, and the efficiency is improved effectively.

Description

technical field

[0001] The invention relates to a manufacturing process of arc side walls, in particular to a manufacturing process of rail freight car arc side walls. Background technique

[0002] With the development of society and the addition and expansion of global railway facilities, the demand for railway transportation of mineral resources has been greatly improved. At present, the railway wagons responsible for the transportation of mineral resources are mainly gondola cars and hopper cars. Most of the hopper cars use arc side wall structures, mainly composed of arc side wall panels, upper side beams, lower side beams and reinforced beams. It is convenient to increase the volume of the car body, and the design of the controlled bottom door structure realizes the automatic unloading of granular or massive bulk goods. It has become one of the main railway wagons for transporting mineral resources.

[0003] Due to the different technical parameters of the vehicle, the...
