摘要 | PURPOSE: A device is provided to produce the end of a stainless forging rivet in a round shape for a convenient use and to form a hole. CONSTITUTION: On operating a header machine, a material(30) is cut and stops in front of a first metal mold(9). Then, the material is inserted into an insertion(5) of the first metal mold by a punch(14) and a pin(6) to form a hole. A second punch(3) moves to the first metal mold and an operating bar(8) of the first metal mold pushes the material. The material is inserted into an insertion(2) of the second punch. The ends(1)(7) of the insertions are in a round shape so that the end of the material is in a round shape. The insertion is prevented from being narrower by a hole supporting bar(12) of the material. The second punch returns back and the hole supporting bar pushes the material. Therefore, a stainless forging rivet is finished. | ||||||
