Description

A bending machine with automatic loading and unloading structure

technical field

The invention relates to the field of bending machines, and more particularly, to a bending machine with an automatic loading and unloading structure.

Background technique

Bending machine is a kind of forging machine, mainly used for the processing of sheet metal. It is a working process in which the pressure generated by the hydraulic system is transmitted through the die to finally obtain the desired shape of the material. By bending the material into shapes with different angles , in order to meet the different material processing requirements in the machining process.

In the feeding process of the existing bending machines, most of them use vertical lifting and feeding or horizontal conveying and feeding, in which lifting and feeding requires manual handling, and continuous conveyor belts are generally used for feeding and feeding.
