The invention provides a wedge punching mechanism for any inclined bottom surface, which comprises a sliding seat, a sliding block and a mandrel, wherein two side baffles are arranged side by side at the upper end of the sliding seat; a guide rail is fixedly connected between the side baffles; the sliding block is connected with the sliding seat in a sliding way through the guide rail; a fixing plate is fixedly connected with one end of the sliding block in the sliding direction of the sliding block; a wheel groove is formed in the other end of the sliding block; a mandrel hole, which makes the wheel groove communicate with the outside, is formed in each side wall of the wheel groove; the mandrel passes through the mandrel holes and is fixedly connected with the sliding block through a pin; the external circular side wall of a roller and the external circular side wall of the mandrel are subjected to high-frequency quenching; a copper sleeve sleeves the mandrel; the copper sleeve is made from a copper alloy; and a graphite column is embedded in the inner circular side wall of the copper sleeve. According to the wedge punching mechanism for any inclined bottom surface, provided by the invention, the friction between the roller and the mandrel and the abrasion of the wedge punching mechanism caused during machining are reduced, and the service life of the wedge punching mechanism is prolonged; and meanwhile, the impact force transmission efficiency of the wedge punching mechanism is improved, and energy is saved.
Description
technical field [0001] The invention belongs to the field of stamping dies, in particular to a wedge punching mechanism. Background technique [0002] At present, due to the complex structure of automobile panels, the corresponding stamping molds need to punch holes on various curved surfaces and angles on sheet metal parts. In the prior art, corresponding to the processing requirements of different angles, only a cam mechanism corresponding to one of them can be manufactured to meet the processing requirements. As a result, dozens of wedge mechanisms for various angles often appear in one set of molds. Therefore, the mold design becomes extremely complicated, and the mold cost is also greatly increased. Contents of the invention [0003] In view of this, the present invention aims to propose a wedge punching mechanism for any inclined bottom surface, so as to solve the punching problem caused by the poor versatility of the wedge mechanism in the prior art and cannot be ...
