Description

Plate type material moving and stacking machine

Technical Field

The utility model relates to the technical field of plate material processing, in particular to a plate material moving and stacking machine.

Background

A common processing method for plate materials is bending by a bending machine. After the plate-type material is bent, workers are required to lift out from the bending knife of the bending machine. This is not safe and laborious. The lifted plate-type materials are stacked together for field management. This is true because bending machines need to be equipped with at least two people to do this together. The lifting and stacking of the plate-type materials are also caused by manpower, so that the working efficiency is lower; for safety reasons, the bending machine is stopped during the operation process; thus greatly reducing the production efficiency.
