Abstract
Description
technical field
[0001] The invention relates to the technical field of roll forming, in particular to a roll forming machine. Background technique
[0002] The forming of the existing bogie side beam cover plate is usually realized by pressing and bending process. The press bending process requires multiple tool revisions to meet workpiece requirements. The forming precision of the bending process is low and the quality is poor (distortion deformation, side bending deformation, insufficient symmetry, more surface indentations and pits), which affects the quality of subsequent welding and assembly. Contents of the invention
[0003] According to the technical problem raised above, a roll bending machine is provided.
[0004] The technical means adopted in the present invention are as follows:
[0005] A roll bending machine, comprising: a frame; the left and right ends of the frame are respectively symmetrically installed with vertically arranged fixed work roll sets, an...
