Abstract

The invention relates to a manufacturing method of an urban subway window beam, and belongs to the field of mechanical processing and manufacturing methods. According to actual production, the methodcomprises a plurality of steps of processing and adjusting a window beam workpiece, and the conditions, methods and processing sequence of a production process of the window beam workpiece are improved again, so that the window beam workpiece which conforms to the drawing standard is manufactured. According to the manufacturing method, standard process parameters and normalized operating processesare given, so that standard mass production of the window beam workpiece can be realized, and a plurality of inherent defects such as defects of the forming quality of the window beam, the rejectionrate of the window beam workpiece and high productive labor intensity and low working efficiency caused by unreasonable processes of an existing manufacturing process of the window beam are avoided.

Description

technical field

[0001] The invention belongs to the field of mechanical processing and manufacturing methods, and in particular relates to a method for manufacturing window beams of urban railway cars. Background technique

[0002] Such as figure 1 As shown, the window beam blank 1 of the urban railway car is a 4 mm thick unequal B-shaped aluminum part, which is a door-shaped bent rib plate with a second-level step shape in cross section, and the two parallel edges of the rib plate Called different surfaces, the two different surfaces are connected to each other through the facade. The width of the first-order different surface in the vertical direction is 25 mm, the height of the facade is 20 mm, and the width of the second-order different surface is 35 mm.

[0003] The existing window beam manufacturing process generally adopts the traditional processing and forming method of forming with a vibrating hammer and then manually assisting in shaping. Due to the special secon...
