Bending lower die and bending machine with the same

Abstract

The invention discloses a bending lower die and a bending machine with the same. The bending lower die comprises a lower die body, the lower die body comprises two adjacent press bending surfaces, each press bending surface is equipped with a U-shaped groove and at least two V-shaped grooves, and the openings of the U-shaped groove and the V-shaped groove are located on a same plane. According tothe bending lower die provided by the invention, each press bending surface of the lower die body is equipped with the U-shaped groove and at least two V-shaped grooves, so that people can make selection according to needs, thus saving the production cost. According to the invention, the lower die body is also equipped with the two press bending surfaces, when one press bending surface is damaged,the bending lower die can be turned over directly, and the other press bending surface can be used. The invention also provides a bending machine, a drive shaft is disposed at the middle part of a pedestal in the bending machine, a positioning piece is disposed on a fixed surface of the bending lower die, and the operation staff can move the bending lower die and select the bending grooves on thepress bending surfaces targetedly to match the bending requirements of different parts, thus saving human resources and improving the production efficiency.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a lower bending die and a bending machine with the lower bending die. Background technique [0002] With the development of society, people are increasingly inseparable from mechanical products, such as vehicles, machine tools, electrical appliances, etc. in their lives. These mechanical products often need to be bent during the production process, which is inseparable from the bending machine. [0003] A bending machine is a machine that can bend various plastic or metal sheets, and its structure mainly includes a bracket and a workbench. The upper and lower bending dies are respectively fixed on the upper and lower worktables of the bending machine, and the bending and forming of the plate is realized by using manual, electromagnetic force or hydraulic pressure, combined with the shape of the upper and lower bending dies. [0004] When the bending machine is in use, the u...

AI Technical Summary

Problems solved by technology

[0004] When the bending machine is in use, the upper bending die and the lower bending die need to be used together to realize the bending process of the material. However, the existing lower bending dies are easy to wear during use, and cannot be replaced in time after wear, which affects the bending process. Bending effect, product quality and production efficiency

At the same time, according to the bending requirements of different parts, it is very cumbersome to replace the lower bending die, which prolongs the production cycle, increases the production cost, and brings a burden to the enterprise
