Die Design of Structural Frame for Reduction of Processes

물류 저장용 조립식 프레임의 제조 공정 단축을 위한 금형설계

Bending is one of the most common cold-stamping operations, recently it is many used to produce structural frame. Depending on the shape and dimensions of complex structural frame, a successive bending operation with simple dies may be economic. But, in this paper, it has been focused to reduce the bending operations by a successive-action compound die. Designed compound-die consists of blank-holder, cam, wedge and etc. In the result, this compound-die for structural frame enabled that it makes seven bending processes into one process, and improved productivity.
