Most of the door panels on the market are made of metal materials, and the refrigerator door panel needs to be punched when processing it.

[0003] Chinese patent publication number CN218452540U discloses "a precise punching device for refrigerator door panels", including a punching table, a fixing adjustment mechanism, a punching guide mechanism and a punching edge material collection mechanism. The punching table is surrounded by grooves, and there are four groups of grooves. A threaded rod is provided in the groove for rotation, and a threaded sleeve is provided on the threaded rod. A motor is fixedly provided at the edge of the punching table, and the output end of the motor is drivingly connected with the matching threaded rod. A fixing frame is fixed above the threaded sleeve, a punching guide mechanism is provided on the punching table, and an edge material collection mechanism is provided below the punching table. The utility model drives the threaded sleeve and the fixing frame to move toward each other through the rotation of the threaded rod, and clamps the refrigerator door panel during processing, and moves the fixing frame in parallel to promote the precise movement of the refrigerator door panel, thereby solving the problem that the manual pushing of the refrigerator door panel has low precision and is prone to errors.
