Combined roller structure for cold bending forming machine

Abstract

The invention relates to a combined roller structure for a cold bending forming machine, including an upper shaft, an upper roller, a lower roller and a lower shaft, wherein the upper shaft is fixed with the upper roller, the lower roller is fixed with the lower shaft, and the rotation of the upper shaft and the lower shaft drives the upper roller and lower roller to rotate. The invention is characterized in that: one end of a first connection plate is connected to a first auxiliary bearing seat, the other end is connected with a second auxiliary bearing seat, the first auxiliary bearing seat is connected to the upper shaft through a first bearing so as to prevent the first auxiliary bearing from rotating on the upper shaft, one end of a second connection plate is fixed with the first auxiliary bearing seat, and the other end of the second connection connecting plate is fixed with a small shaft. The combined roller structure has the advantages that the structure is simple, compact and reasonable; when a plate is in contact with a vertical roller, an auxiliary roller can rotate passively, idle bending is avoided during the forming process of the plate, and the original elastic deformation is changed into plastic deformation; the press marks on the surface of the formed plate are obviously reduced, and the surface is smooth and flat.

Description

technical field [0001] The invention relates to a combined roll structure of a cold bending machine, in particular to the arrangement of combined rolls for various cold bending machines during bending and forming, and belongs to the field of mechanical manufacturing. Background technique [0002] At present, when the rolls of ordinary cold bending machines form large arcs, the empty bending method is generally used. It mainly uses the combination of upper and lower rolls and cross rolls. By calculating the bending angle, the plate can be smoothly bent in the cavity during the production process. and forward. After elastic deformation, empty bending phenomenon will occur, causing many empty bending indentations, which will affect the appearance of formed products. Contents of the invention [0003] The purpose of the technology of the present invention is to overcome the above disadvantages, thereby providing a combination roll structure of a cold roll forming machine, whi...
