Automobile tractor bracket punching die

Abstract

The invention discloses an automobile tractor bracket punching die. The automobile tractor bracket punching die comprises an upper die base and a lower die base. An upper die plate is fixedly installed on the inner side surface of the upper die base. A lower die plate is fixedly installed on the lower die base. A material pressing plate is fixedly installed on the inner side surface of the upper die plate. Guide sleeves are arranged on the two sides of the inner side surface of the upper die plate correspondingly. Guide columns are fixedly installed on the two sides of the upper surface of the lower die plate correspondingly. The guide columns are embedded in the guide sleeves in a sleeved mode and slide up and down along the inner walls of the guide sleeves. A plurality of punching heads are installed on the inner side surface of the upper die plate. A protection sleeve is arranged around the outer side of each punching head. According to the automobile tractor bracket punching die, the tail of each punching head is provided with a guide groove, the pressure of the punching heads has buffer time, an incision of a punched part is prevented from being crushed, and the yield is ensured; an air injection pipe is arranged, so that the punching heads are timely cooled, and the service life of the punching heads is prolonged; the structure is reasonable and compact; tractor bracket series products can be punched out through adjusting and positioning of the guide sleeves and the guide columns, the die production cycle is greatly shortened, and the cost is reduced; and meanwhile, the punching heads are protected by arranging the protection sleeves on the outer sides of the punching heads, so that the fracture coefficient of the punching heads is greatly decreased, and safe and reliable operation of the die is ensured.
