specific Embodiment approach 1

[0024] Specific implementation mode 1. Combination Figure 1 to Figure 5 Describe this embodiment, a method for forming and correcting the reinforcement plate under the window of the stainless steel side wall, the method is realized by the following steps:

[0025] 1. Innovate the drawing lubricating medium, and use film protection for drawing forming, such as figure 1 , The raw material does not have a film, it is placed before drawing and forming, and the workpiece will crack without adding a film. Therefore, double-layer plastic films are used on the upper and lower sides of the blank.

[0026] During the drawing forming process of the mold, the double-layer plastic film is placed on the upper and lower sides of the blank to obtain the formed part, which not only meets the lubrication function during the drawing process, but also protects the surface of the mold and the part surface. The double-layer plastic film can ensure that the material is fully and evenly extended, ...

Abstract

A forming and correcting manufacturing method for a reinforcing plate under a side wall and a window of a stainless steel side wall, which relates to the technical field of stamping technology, solves problems such as forming difficulties in forming a reinforcing plate under a side wall and a window, and cannot meet production requirements. In the process, a double-layer plastic film is placed on the upper and lower sides of the blank to obtain the formed part; the auxiliary materials around the formed part are cut off by a three-dimensional laser cutting machine, and the formed part is corrected; The corrected parts are adjusted and repaired with the modification inspection tool to obtain the reinforcement plate under the side wall and window. The under-the-window reinforcing plate tooling manufactured by forming and correcting according to the present invention is used to improve the arc correction efficiency, ensure the flatness of the under-window reinforcing plate, and improve the efficiency of repairing the size of the four sides of the under-window reinforcing plate to press the horse legs; the under-window reinforcement The sequence of panel wrinkle removal methods is determined to improve production efficiency and ensure that the arc of the reinforcement panel under the window, the depth point, line and surface of the horse leg are qualified.

Description

technical field [0001] The invention relates to the technical field of stamping technology, in particular to a method for forming and correcting a reinforcing plate under a window of a stainless steel side wall, and the invention is applicable to a process for manufacturing, processing and forming a reinforcing plate under a window of an urban railway vehicle. Background technique [0002] The existing side wall adopts a new structure, and the reinforcement plate is formed by drawing with a mold and corrected by a vibrating hammer. The stretching amount is close to the limit of the material, and forming is difficult. The mold has been repaired and changed many times, but it still cannot meet the requirements of the drawing. It takes a long time for multiple people to participate in the hammer correction and manual adjustment, which cannot meet the production demand and poses great risks to the steel structure of the car body. Contents of the invention [0003] The inventi...
