Integration Forming Technology based on Cold Hot Forging of Clutch Jaw Parts for Farm Machinery

Abstract

ARTICLE INFO ABSTRACTArticle history:Forging is a manufacturing process involving the shaping of metal using localized compressive forces and the process of deforming metal into a predetermined shape using certain tools and press according to the temperature. Forging provides stronger metal parts than that possible by casting or machining. Conventional clutch jaw parts have been developed through cold forging and precision machining; however, fabrication of integral clutch jaw parts for farm machinery has not been reported yet. These parts were developed by applying a complex forging technology combining cold and hot forging. The integrated forming technology proposed in this study will be useful for reducing the lead-time for manufacturing, improving the accuracy of products, and eliminating the welding process. , 보론강 튜브를 이용한 열간 성형해석에서 마찰계수 0.4가 적용 되었다 [2] . 냉간 단조 공정에서는 튜브의 유동성형(flow forming) 을 이용한 중공형 부품이 개발되었고 [3] , 다단 공정에 대한 연구 등 이 진행되었다 [4][5][6][7][8] .복합단조 기술은 현재 포마 공정과 냉간 공정으로 적용되고 있으
