Abstract
The invention belongs to the technical field of punching dies and particularly relates to a guide plate type punching die. The guide plate type punching die comprises a lower die base arranged fixedly and an upper die base arranged in an up-down reciprocating mode. The upper die base is provided with a punching head. The lower die base is provided with a female die body. A side guide plate is arranged above the female die body. A fixing plate is arranged above the side guide plate. A through hole is formed in the middle of the fixing plate and internally provided with a movable guide plate. The middle of the movable guide plate is provided with a hole channel. The punching head is slidably matched with the movable guide plate and further sleeved with a polyurethane rubber mat. When the upper die base descends, the polyurethane rubber mat extrudes the movable guide plate to enable the movable guide plate to make contact with a workpiece at first and press the workpiece, and then the upper die base continues to descend to fold the punching head with the female die body, so that the punching action is completed. Compared with a spring, the pressure provided by the polyurethane rubber mat is more reliable; and in addition, the punching head can have a very good guide condition through the movable guide plate, and a thick material can be punched through a small male die.
