[0002] Curved cabinets are commonly seen in information exchange equipment installed in banks, hospitals, shopping centers and other places. Their tops are tilted backwards to make it more comfortable for users to operate. The front and back panels of the curved cabinet shells need to be bent. The current mainstream processing method is to use pressure equipment and molds for bending, but this production method has some disadvantages: for curved cabinet panels with thin thickness, low strength but relatively large area, small pressure equipment cannot accommodate them and cannot be processed, while the production cost of using large stamping equipment is too high, and there are problems with equipment applicability. In addition, the molds used by pressure equipment are generally manufactured by CNC machine tools, which also leads to high production costs.
