A stress-relieving high-speed rail car group manufacturing body leveling device

Abstract

The invention discloses a leveling device for manufacturing a body of a stress-relieving high-speed rail vehicle group, which relates to the technical field of high-speed rail production. A feeding box is arranged on the top of the right side of the feeding box, the inner two sides of the feeding box are connected with a limit push component, and the inner side of the limit push component is arranged with a steel plate of the vehicle group. In the present invention, the vertical arrangement of the upper leveling components is the same as that of the lower leveling components, and can be combined into a straight line with the same radian as the lower leveling components through the working energy of the second hydraulic cylinder. When leveling, the steel plate of the train group can be leveled into a steel plate with a specified radian. Because the high-speed rail body considers the wind resistance, most of them have a certain radian. All the required steel plates of the vehicle group are flattened into the required shape, which is beneficial to improve the flexibility of the equipment.

Description

technical field [0001] The invention relates to the technical field of high-speed rail production, in particular to a body leveling device for stress-relieving high-speed rail vehicle groups. Background technique [0002] High-speed railway, referred to as high-speed railway, refers to a railway system with high design standards and safe high-speed running of trains. Its concept is not limited to tracks, nor does it refer to trains. High-speed rail has different regulations in different countries, different eras, and different scientific research and academic fields. The "High-speed Railway Design Specification" document issued by the State Railway Administration of China defines high-speed rail as a new design. A passenger-dedicated railway with a speed of 250 kilometers (inclusive) to 350 kilometers (inclusive) per hour, and the standard gauge of the EMU train. The body of the high-speed train is usually made of aluminum alloy steel plate. The leveling machine is used to ...

AI Technical Summary

Problems solved by technology

[0003] Common leveling machines on the market can only level aluminum alloy steel plates into a standard straight line, because most high-speed rail bodies have a certain curvature, which makes it difficult for conventional leveling machines to level all the aluminum alloy steel plates required for high-speed rail bodies. Flatten into the desired shape
