Description

Technical Field

[0001] The invention relates to the technical field of plate bending equipment, and in particular to an automatic corrugated plate forming bending machine. Background Art

[0002] Corrugated plate refers to a thin steel plate processed into a wavy or continuous trapezoidal shape, and is often processed using a forming bending machine.

[0003] During the use of the existing forming bending machine, the thin steel plate is bent by the upper and lower dies of the bending machine and then taken out manually. Usually, a bending machine can only bend thin steel plates of one size, and its practicality is poor. Usually, in order to bend the thin steel plate into different shapes, the staff will replace the upper and lower dies. During the replacement process, the bending machine needs to stop working, and the thin steel plate can no longer be bent, which reduces work efficiency. The upper and lower dies are often installed and fixed with bolts, which results in a waste of time when the upper and lower dies are replaced, thereby reducing production efficiency. The bent corrugated plates are taken out manually one by one, which not only increases the labor intensity of the staff, but also reduces work efficiency, and the degree of automation is low.
