During the use of an existing bending machine, the thin plate to be bent is placed on a workbench, and the upper bending die is downward, and the thin plate is bent together with the lower bending die. Hydraulic bending machines are widely used in workpiece bending operations because of their simple operation, low cost and fast response speed.
