In addition, most of the current sheet metal bending equipment uses manual single loading and unloading for semi-automatic work, which is becoming increasingly unable to meet the increasing production demand.

[0003] In the existing bending equipment, such as the Chinese patent application CN117619948A, the bent sheet metal parts are unloaded by linking the unloading part with the bending part, and the loading part is linked with the unloading part to load the bending table. The operation is simple, no additional power source is required, and the degree of automation is high. The bending part can be automatically loaded and unloaded, and no staff is required to unload the materials. After the device has been running for a period of time, the sheet metal can be filled on the placement plate in the vacant position. One staff member can operate multiple machines, with low labor costs and high work efficiency.
