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

The invention relates to a forming correcting manufacturing method for a reinforcing plate under a stainless steel side wall window, relates to the technical field of stamping processes, and solves the problems that an existing forming method of the reinforcing plate under the side wall window is difficult in forming and cannot meet the production requirement. According to the method, in the molddrawing forming process, a double-layer plastic film is adopted to be placed on the upper side surface and the lower side surface of a blank to obtain a formed workpiece; a three-dimensional laser cutting machine is used for cutting auxiliary materials of the periphery of the formed workpiece off, and forming correction is carried out on the cut workpiece; and a shaping detection tool is used foradjusting and repairing the corrected workpiece, and the reinforcing plate under the side wall window is obtained. According to the tooling manufacture of the formed corrected and manufactured reinforcing plate under the window, the arc correction efficiency is improved, the flatness of the reinforcing plate under the window is guaranteed, and the horse leg pressing and size repairing efficiencyof the four sides of the reinforcing plate under the window is improved, the sequence of a method for removing wrinkles of the reinforcing plate under the window is determined, the production efficiency is improved, and the arc of the reinforcing plate under the window is guaranteed, and the depth point, the line and the surface of a 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...
