Problems solved by technology

[0005] In order to solve the unreasonable process of the existing window beam manufacturing process, resulting in high labor intensity, low work efficiency, and easy defects in the forming quality of the window beam, the hammer forming mold is used to hammer the different surfaces of the window beam workpiece. During operation, when the working pressure adjustment of the vibrating hammer and the change of the processing position deviate, the stress change values ​​of the window beams will be different, which will lead to deformation of the different surfaces and facades of the window beams, and the different surfaces will be subjected to twisting forces. The façade is subjected to bending force, and the angle changes, causing the window beam to be corrected and formed too large, resulting in the technical problem of requiring secondary repairs or even the direct scrapping of the window beam workpiece. The invention provides a method for manufacturing the window beam of an urban railway car

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 and figure 2 As shown, when specifically applying the manufacturing method of the urban railway car window beam of the present invention, the following steps are performed:

[0031] Step 1: Execute the preparation work before processing, which specifically includes the following sub-steps:

[0032] Step 1.1: Check whether the material, size and appearance quality of the blank 1 of the window beam meet the technical requirements of the drawings, and repair or replace the blank 1 of the window beam that does not meet the inspection requirements;

[0033] Step 1.2: Check whether the working pressure of the hammer forming equipment, the FWA802 / 4X compression mold, and the SW4T calendering mold are in good condition, and adjust them to normal working conditions;

[0034] Step 1.3: Check whether the working pressure of the vibrating hamm...

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...
