Flexible roll bending numerical control plate bending machine

Abstract

The invention relates to the technical field of plate bending machines, in particular to a flexible roll bending numerical control plate bending machine. The machine comprises a base. A feeding box body and supporting columns are fixedly connected to the outer surface of the upper end of the base, the supporting columns are distributed behind the feeding box body in a bilateral symmetry manner, a driving roller and a driven roller are arranged between the two supporting columns, and the driving roller is located over the driven roller, and first hydraulic cylinders are fixedly connected to the outer surfaces of the upper ends of the supporting columns correspondingly. Plates with different diameters in the bending treatment process are lifted up through supporting blocks, the situation that the plates hang down and deform under the influence of gravity is avoided, the application range is widened, meanwhile, when the plates are fed, the plates with different widths are clamped and limited through limiting rollers on the two sides, the bending effect is prevented from being affected by position deviation generated during manual feeding, feeding is assisted through feeding rollers, the friction force is reduced, the pushing force of a worker for pushing a plate is conveniently reduced, and the overall working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plate rolling machines, in particular to a flexible bending numerical control plate rolling machine. Background technique [0002] The plate rolling machine is a kind of equipment that uses work rolls to bend the sheet material. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. Due to the different fields of use of the plate rolling machine, The types are also different. From the number of rolls, it is divided into three-roll plate rolling machine and four-roll plate rolling machine. The three-roller is divided into symmetrical three-roller plate rolling machine, horizontal downward adjustment three-roller plate rolling machine, arc downward adjustment type plate rolling machine, upper roller universal three-roller plate rolling machine, and hydraulic numerical control plate rolling machine. [0003] However, the existing smal...

AI Technical Summary

Problems solved by technology

[0004] 1. When the plate is being bent, the part of the plate above the driving roller is prone to fall under its own gravity, resulting in deformation of the plate arc and affecting product quality;

[0005] 2. When the board is fed, due to the error caused by manual operation, the position of the board is shifted when feeding, resulting in unqualified processing of the board
