Abstract

본 발명은 압출가공된 강재컵(steel cup)에 동재링(copper ring)을 압착시키는 가공방법에 관한 것으로서, 프레스기계에서 금형을 사용하여 강재컵을 냉간단조하여 선반으로 소정의 가공을 한 후에 미리 준비된 동재링을 끼운 상태에서 프레스기계에서 재차 압출을 시도하여 동재링을 강재컵에 압착시키는 것으로, 물리적인 기계적 강도가 대단히 우수할 뿐 아니라 금속내부적인 조직도 대단히 안정하고, 기계가공에서나 얻을 수 있는 강제컵 내부의 세밀한 형상까지도 종래의 기술에 비해서 짧게 적은 공정으로 프레스 가공할 수 있기 때문에 프레스 가공비를 절감할 수 있고, 특히 동재링이 압출되면서 강재컵에 압착되었기 때문에 대단히 큰 압착력을 지니게 되어 본 발명의 본래의 목적인 이종금속간의 압착력을 크게 한다는 소정의 목적을 달성하기 위함이다.The present invention relates to a processing method for crimping a copper ring to an extruded steel cup, in which a cold working of the steel cup using a mold in a press machine is performed in advance on a lathe. By extruding again from the press machine while the prepared copper ring is inserted, the copper alloy ring is pressed into the steel cup. It is not only excellent in mechanical strength but also very stable in the internal structure of metal. Even the detailed shape inside the cup can be pressed in a shorter process compared to the prior art, thereby reducing the press working cost, and in particular, since the copper ring is pressed into the steel cup while being extruded, it has a very large compressive force. To achieve a certain purpose of increasing the pressing force between dissimilar metals, which is an original purpose The.
