In this way, as many slots as there are in the stator and rotor pieces, it must be punched as many times as possible, resulting in severe wear of the punch and die on the mold. It is necessary to repeatedly disassemble the punch and die, and then perform position calibration after grinding the cutting edge. Guarantee the position accuracy of the groove shape of the punch before and after grinding, which affects the product quality, and the labor intensity is high and the work efficiency is low

The invention relates to a puncher pin positioning device of a punching press machine. The puncher pin positioning device comprises a mould handle, a square positioning hole, a mould handle fixing plate, a positioning pin, screws, an upper mould, a puncher pin and the like. The mould handle is of a cylinder and square integrated structure, the upper end of the mould handle is a cylinder which is fixed on the punching press machine by the tightening screws, the lower end of the cylinder is a square, the lower end of the square and the square positioning hole on the mould handle fixing plate are fixed through fit clearance, and therefore, the puncher pin can be disassembled and replaced conveniently. The upper mould is arranged at the lower end of the mould handle fixing plate, the upper mould and the mould handle fixing plate are positioned through the positioning pin and fastened through the screws, and the puncher pin is arranged on the lower end surface of the upper mould. During using of the puncher pin positioning device, when the puncher pin and a concave mould need replacing, the puncher pin and the concave mould can be replaced after disassembling the mould handle fixing plate and a lower mould, and position accuracy after the puncher pin and the concave mould are assembled is effectively guaranteed.
Description
technical field [0001] The invention relates to a positioning device for punching a punching motor, in particular to a punch positioning device for a punching press. Background technique [0002] We know that at present, when punching the stator and rotor of a motor, it is generally used to blank first, punch out the outer contour of the stator sheet and the inner hole of the rotor sheet, and then use the inner hole of the rotor sheet to position on the single punching machine, and punch out separately. , Rotor sheet. In this way, as many slots as there are in the stator and rotor pieces, it must be punched as many times as possible, resulting in severe wear of the punch and die on the mold. It is necessary to repeatedly disassemble the punch and die, and then perform position calibration after grinding the cutting edge. Guaranteeing the position accuracy of the groove shape of the punching sheet before and after grinding affects the product quality, and the labor inten...
