Hydraulic large plate leveling device

Abstract

A hydraulic leveling-up machinefor large-size thin sheet is composed of stretching unit, sliding clamp unit, fixed clamp unit, working platform, feeding-stripping unit, slide table unit, hydraulic station and console.

Description

technical field [0001] The invention relates to a hydraulic metal thin plate leveling machine, in particular to a leveling device suitable for large-size thin plate coils. Background technique [0002] At present, the domestic prefabrication methods and equipment of large-size thin plates (length > 10m, width > 1.2m) are relatively backward, especially the side wall panels of domestic large-scale road buses and rail cars. The manufacturing process is backward and the welding process is complicated , There are many welds, and the surface quality of the welded side wall panels is poor. Due to defects in the welding quality of the weld or fatigue during use, the weld of the side wall panel of the bus is easy to crack, which affects the service life and surface quality of the bus. In order to solve the above problems, a new process method of manufacturing passenger car side wall panels with large panels is adopted, and the original method of welding more than 20 small pan...

AI Technical Summary

Problems solved by technology

[0002] At present, the prefabrication methods and equipment of large-size thin plate (length > 10m, width > 1.2m) panels are relatively backward in China, especially the side wall panels of large-scale road buses and rail vehicles in China. The manufacturing process is backward and the welding process is complicated , There are many welds, and the surface quality of the welded side wall panels is poor

Due to defects in the welding quality of the welds or fatigue during use, the welds of the bus side wall panels are prone to cracking, which affects the service life and surface quality of the bus
