Abstract

The invention discloses a method for manufacturing a sidewall panel of a railway passenger vehicle. The method comprises the following steps: placing the panel and cutting the panel into big panels of a predetermined size; and processing the big panels by a mechanical processing method. The method of the invention adopts a simple technical scheme, is low in manufacturing cost and can effectively reduce the deformation during the manufacturing of the sidewall panel and improve the quality of the sidewall panel.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for manufacturing a side wall panel of a railway passenger car. Background technique [0002] In the manufacture of rail vehicles made of carbon steel, the manufactured underframe, roof, side wall panels and end wall panels are usually assembled together, and then the steel structure of the car body is assembled as a whole, and the side wall panels are generally passed through After cutting on the roll board, it is made by chemical treatment process. [0003] At present, there are generally two kinds of production processes for side wall panels: the first is the small panel production process, which is to first cut the coiled panels into small panels, and after chemical treatment of each small panel, then each small panel Welding into large boards to obtain side wall panels; the second is the large board manufacturing process, which is to cut the coiled bo...
