Sheet metal bending device and bending method

Abstract

The invention discloses a sheet metal bending device and a bending method. The sheet metal bending device comprises a base, wherein an inverted L-shaped support is fixedly mounted on one side of the top of the base, a hydraulic cylinder is fixedly mounted at the top of the inner wall of the inverted L-shaped support, a mounting groove is formed in the middle of the top of the base, a second rotating motor is fixedly mounted in the mounting groove, and the output end of the second rotating motor is fixedly connected with a second rotating shaft. According to the sheet metal bending device and the bending method, through the corporation of a circular rotary plate, a bending device, a lower mold base, the hydraulic cylinder, an inlet-outlet opening, an upper mold base, a limiting block, a limiting rod, a spring, the second rotating shaft, the mounting groove, the second rotating motor, a storage groove and a forming cavity for use, the working intensity of workers is greatly reduced, andthe sheet metal bending efficiency is improved; and meanwhile, the storage groove can define the position of a metal plate, so that shifting of the metal plate before the metal plate is bent can be avoided, the sheet metal bending quality is improved, and the workers can conveniently place the metal plate.

Description

technical field [0001] The invention relates to the field of sheet metal bending, in particular to a sheet metal bending device and a bending method. Background technique [0002] Sheet metal is a processing technology, and sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching / cutting / compositing, folding, riveting, splicing, Forming (such as car body), etc. Its remarkable feature is that the thickness of the same part is consistent. Under the pressure of the upper die or lower die of the bending machine, the metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is free to bend. Apply pressure, the sheet material and the inner surface of the V-groove of the lower mold gradually get ...

AI Technical Summary

Problems solved by technology

[0003] Bending is a kind of sheet metal processing. However, the structure and design of the traditional sheet metal bending devices currently on the market are not optimized enough. When they are used, manual loading, bending, and unloading are required. Then the material is loaded sequentially, the workers have less rest time, the work intensity is high, and the bending efficiency is low
