Abstract

앵커볼트의 헤드부를 단조가공하여 제작성과 품질을 향상시킬 수 있게 한 앵커볼트의 헤드부 가공방법 및 그 장치에 관한 것으로, 종래의 앵커볼트를 가공하기 위한 기술은 환봉상으로 준비된 재료를 선반등의 절삭기계를 이용하여 절삭가공 하거나, 금형을 이용하여 사출성형하게 됨으로써 생산성 및 품질이 저하되는 문제점이 있었는 바, 따라서, 가공하기 위하여 준비된 소재의 일단부를 고정다이로부터 돌출되게 고정시킨 상태에서 소재의 돌출된 단부를 원하는 형상의 성형홈이 구비된 가동 다이에 진입되게 한 후 펀치로 강압하여 소재의 단부를 변형시켜 대단부를 형성하게 됨으로써, 제품의 치밀도를 높이고 제작설비를 감축시켜 생산성과 품질을 제고시킬 수 있게 됨을 특징으로 한다. 를 포함한 구성을 특징으로 한 것이다.The present invention relates to an anchor bolt head for machining an anchor bolt, and a method for machining an anchor bolt head. The present invention relates to a method for machining an anchor bolt head, There is a problem in that productivity and quality are lowered by cutting or machining using a cutting machine or injection molding using a metal mold. Therefore, in the state where one end of the material prepared for machining is fixed so as to protrude from the fixed die, And the end portion of the material is deformed to form the large end portion. Thus, the compactness of the product is increased and the production facilities are reduced to improve the productivity and quality. . And the like.
