Three-dimensional roll bending forming device and method applying same

Abstract

The invention provides a three-dimensional roll bending forming device, which comprises a base, an X-direction motion drive mechanism, an X-direction ball screw assembly and a forming rack provided with a roll, wherein the forming rack is movably connected with the base. The three-dimensional roll bending forming device also comprises a Z-direction motion drive mechanism and a Z-direction ball screw assembly, wherein the Z-direction motion drive mechanism and the Z-direction ball screw assembly are vertically arranged; the Z-direction ball screw assembly comprises a Z-direction ball screw and a Z-direction nut assembly which is in rolling connection with the Z-direction ball screw through a ball; and one end of the Z-direction ball screw is linked with the Z-direction motion drive mechanism, and the Z-direction nut assembly is fixedly connected with the forming rack. Therefore, the three-dimensional roll bending forming device is capable of moving in an x and a y planes, and also moving in the Z-axis direction when raw materials are subjected to bending deflection operation; and the accuracy of carrying out bending deflection on the raw materials is improved, three-dimensional processing on the raw materials is realized, and the section bar obtained by processing has reasonable mechanical property.

Description

technical field [0001] The invention belongs to the technical field of cold bending forming in mechanical processing, and in particular relates to a three-dimensional roll forming device and a method for applying the device. Background technique [0002] Roll forming is a material-saving, energy-saving and efficient metal forming process technology. The processing method is as follows: using metal sheets or coils as raw materials, the raw materials are gradually bent and deformed by a forming machine equipped with roll moulds, so as to obtain products with required cross-sections. Generally, each forming machine is equipped with two or more forming rollers, and each forming unit consists of more than two forming machines. [0003] The roll mold of the existing roll bending equipment can only bend and deform the raw material on the x and y planes. Since there is only one working plane for bending and deformation, the precision of bending and deforming the raw material is lim...

AI Technical Summary

Problems solved by technology

[0003] The roll mold of the existing roll forming equipment can only bend and deform the raw material on the x and y planes. Since there is only one working plane for bending and deformation, the accuracy of bending and deforming the raw material is limited, which in turn limits the roll forming equipment. Applications
