In sheet metal production, the bending device is used to bend the plate according to the specified requirements, which has been widely used in the field of sheet metal production.

[0003] The existing bending device is generally divided into two types of mold replacement and supporting plate angle adjustment. The mold replacement device uses the pressure provided by the hydraulic system to press the workpiece into the die with the punch to form the required bending angle. When bending sheet metal of different angles, the bending mold needs to be replaced, so different angle molds need to be reserved, thereby increasing the cost. The supporting plate angle adjustment device is generally single-sided adjustment, and the other side needs to be fixed by the fixed downward mechanism. The start-stop control of the fixing mechanism needs to increase the electrical system or hydraulic system, and the operation is very inconvenient. Therefore, the technical personnel in the field provide a sheet metal bending device to solve the problems in the background technology. SUMMARY
