A precision punching die

Abstract

The utility model discloses a kind of precision punching die, containing upper die plate, lower die plate, with type positioning block, limit cylinder mounting seat, limit cylinder, matrix, punch. Upper die plate is located above lower die plate, and punch moves to its with upper die plate. Lower die plate is equipped with limit cylinder mounting seat, limit cylinder, with type positioning block, matrix. With type positioning block is adjacent with matrix, matrix is below punch and has punching, and the upper surface of both is adapted to the lower surface of the part to be punched, so that it is completely attached. Limit cylinder is located on lower die plate through mounting seat, and located in with type positioning block side, and limit baffle is equipped on the side of with type positioning block away from cylinder, and cylinder piston rod is connected with elastic buffer block, and the both clamps part. Through the above design, the technical problem that punching precision is poor due to vibration of thin-walled plate part during stamping can be solved.
