Abstract

The invention discloses a fillet cutting and punching die for automobile manufacturing. The die comprises an upper die plate and a die handle fixed on the upper die plate, wherein a punch head is detachably connected with the die handle through a connecting assembly; the connecting assembly comprises a mounting ring and a screw; the bottom end of the die handle is sequentially provided with a mounting hole, an extrusion hole, a yield hole and a matching hole from bottom to top, wherein the extrusion hole is a conical hole, and the large-diameter end of the extrusion hole is in communication with the mounting hole; a collar is arranged on the punch head; the mounting ring is arranged on the punch head in a sleeving mode, the top end of the mounting ring is protruded upwards into a conical extrusion ring, the slope of the side wall of the extrusion ring is greater than the slope of the hole wall of the extrusion hole, the side wall of the extrusion ring is provided with through holes, and the ends, away from the mounting ring, of the strip-shaped through holes are in communication with the outside; and the top end of the punch head is matched with the matching hole, the collar is matched with the yield hole, the extrusion ring is inserted into the extrusion hole, and the screw is in threaded connection with the hole bottom of the mounting hole after passing through the mounting ring. According to the die, the punch head is disassembled and fixed through the connecting assembly, the later maintenance of the die is facilitated, and the maintenance time cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a fillet punching die for automobile manufacturing. Background technique [0002] On some plate parts used in the manufacture of automobile parts, especially thin metal plates, the forming holes and rounding operations are all punched and formed by punching dies. The blanking die is an indispensable process equipment in stamping production, and a good die structure is a reliable guarantee for the realization of the process plan. The quality and precision of stamping parts mainly depend on the quality and precision of the punching die. Whether the structure of the punching die is reasonable and advanced will directly affect the production efficiency, the service life of the punching die itself, and the safety and convenience of operation. [0003] The blanking die mainly includes an upper die base, a punch fixed on the upper die base, a lower die base, and...
