[0002] Stainless steel sheet is a material made of stainless steel through heat treatment and fine grinding. It has the characteristics of high precision, strong tensile strength, good finish, toughness and not easy to break. When it needs to be made into machine casing or other items, the stainless steel sheet needs to be bent.

[0003] However, when using the existing bending device, the worker needs to hold the stainless steel sheet in his hand and work on the machine tool. Since the bending device needs to bend with a steel knife, it is easy for the worker to have an accident while working. Moreover, most of the existing bending devices rely on engraved lines and the worker himself to align the stainless steel sheet, which can easily cause errors and make the bent stainless steel sheet unusable, which can easily cause economic losses.
