Embodiment Construction

[0017] figure 1 It is a flowchart of a method for manufacturing a side wall of a subway vehicle body provided by Embodiment 1 of the present invention. like figure 1 As shown, the method for manufacturing the side wall of the subway car body provided in this embodiment may specifically include the following steps:

[0018] Step 101, assembling and welding together the lower part of the side wall profile, the lower profile of the side wall window, the profile between the side wall window and the upper profile of the side wall window to obtain a long side wall panel;

[0019] Step 102, cutting the long side wall panels to obtain several side wall panels;

[0020] Step 103 , welding the door columns on both sides of the side wall panels of each block to obtain the side walls of each block.

[0021] The specific implementation process of the above step 101 can be as follows: firstly, on the long side wall plate assembly welding tool, assemble the lower part of the side wall pro...

Abstract

The invention provides a manufacturing method of a side wall of a vehicle body of a metro vehicle. The manufacturing method comprises the following steps of: assembling and welding a side wall lower section, a side wall window lower section, a side wall inter-window section and a side wall window upper section together to obtain a long-side wall board; cutting the long-side wall board to obtain a plurality of partitioned side wall boards; and welding door stand columns on two sides of each partitioned side wall board respectively to obtain each partitioned side wall. After the long-side wall board is obtained through welding, the long-side wall board is cut to obtain the partitioned side wall boards, and the door stand columns are welded for the partitioned side wall boards to finally obtain the partitioned side walls, so that the assembly efficiency of the side wall of the vehicle body of the metro vehicle is effectively increased, the manufacturing cost is reduced, and the side wall profile of the side wall is effectively guaranteed.

Description

technical field [0001] The invention relates to a manufacturing technology of a vehicle body side wall, in particular to a method for manufacturing a subway vehicle body side wall, and belongs to the technical field of rail vehicle body manufacturing. Background technique [0002] There are many doors in the subway car body, and a plurality of block side walls need to be made, and the existing block side walls are all made separately. The fabrication process of each block side wall includes the following steps: [0003] Step 1. According to the length dimension and outline dimension of the block side wall, make a special side wall welding tooling. The tooling requires at least 3 positioning references to ensure the overall size of the workpiece. At the same time, the position of each welding seam needs to be set. clamping device; [0004] Step 2. Use the door column on one side as the positioning reference, place it on the side wall assembly welder, then assemble the door ...
