Abstract

The invention provides a roll forming machine comprising a rack. The left end and the right end of the rack are symmetrically provided with vertical fixed working roller sets respectively, each fixedworking roller set comprises two fixed working rollers arranged front and back, and the upper and lower ends of the fixed working rollers are rotatably connected with the rack respectively. A guide mechanism with a left-right guide function is arranged between every two fixed working rollers arranged front and back. The left and right ends of the rack are symmetrically provided with vertical movable working roller mechanisms respectively. Each movable working roller mechanism comprises a vertical movable working roller and a driving oil cylinder group for driving the movable working roller tomove along the corresponding guide mechanism. The top ends of the movable working rollers are connected with driving devices for driving the movable working rollers to rotate. According to the roll forming machine, roll forming replaces a traditional bending technology, the requirement for product precision can be met, the product quality and the production efficiency can be improved, the production cost is reduced, and the problems of product indentations and insufficient consistency are solved.

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...
