Embodiment Construction

[0024] The manufacturing method of the railway wagon cladding type side wall structure of the present invention, its steps are:

[0025] (1) Sheet uncoiling and pretreatment;

[0026] (2) Sheet blanking and leveling;

[0027] (3) Cutting and jigsawing of side wall panels;

[0028] 1) According to the length and shape requirements of the side wall panels, cut N pieces of equal-length veneers G01, G02...G0N;

[0029] 2) Divide N equal-length veneers G01, G02...G0N into M groups in sequence, with 2 to 4 veneers in each group, and flat-weld several veneers in each group to form M large boards; N consists of The product length is divided by the sheet width to determine.

[0030] (4) Roll the M large slabs into M pieces of arc-shaped side wall panels respectively according to the required radian;

[0031] (5) Side wall assembly and welding:

[0032] figure 2 It is a schematic diagram of the assembly and welding of the outer side of the side wall panel, image 3 It is a schem...

Abstract

The invention provides a manufacturing method of a wrapper plate type side wall structure of a wagon. The manufacturing method comprises the following steps: (1) decoiling and pre-treating a plate; (2) blanking and leveling the plate; (3) cutting a side wallboard and then laminating, i.e., according to the length and shape requirement of a side wallboard product, cutting out N equi-length single plates G01, G02...G0N, dividing the N equi-length single plates G01, G02...G0N into M groups in sequence, wherein each group comprises 2-4 single plates, and then carrying out double-face welding on each group of single plates so as to splice M large plates; (4) respectively rounding the M large plates into M arc-shaped side wallboards according to the required radian; and (5) assembling and welding side walls: successively hanging the M arc-shaped side wallboards on a side wall assembling base seat tire, assembling various arc-shaped side wallboards, carrying out positioning welding after clamping and fixing, carrying out assembling gap welding by using a welding tractor matched with a flexible track, after the side wallboards are turned over, clamping and positioning the inner side faces of the side wallboards, and carrying out continuous full-length welding on the inner side faces of the side wallboards by using the welding tractor matched with the flexible track.

Description

technical field [0001] The invention relates to a method for manufacturing a plate-clad side wall structure of a railway freight car, and belongs to the technical field of railway vehicle body manufacture. Background technique [0002] As we all know, in the steel structure of railway vehicle body, it is mainly composed of underframe, side wall, end wall, roof, etc., among which the side wall is one of the main load-bearing parts. There are deficiencies in the use of the type side wall for the boundary of railway rolling stock and the utilization of the strength of the side wall material. In the later stage of optimization product design, a clad side wall structure is adopted on the funnel car. The utilization of the side wall reduces the weight of the side wall, and the load capacity of the vehicle is improved. However, because the side wall of the cladding board is a circular arc structure, it is more difficult to manufacture. [0003] In the early stage, the cladding boa...
