Progressive Forming Process Design of an Automotive Bracket Part with Computer Simulation

전산해석을 이용한 자동차 브라켓 부품의 프로그래시브 성형 공정 설계

This paper concerns the progressive die design for an automotive bracket part aided by the computer simulation in order to eliminate the inferiority such as the crack. The computer simulation of the progressive forming process is utilized in order to investigate cause of the cracks. This paper proposes a new guideline for the die design which modifies intermediate shapes and adds intermediate forming stages in progressive forming process. The effectiveness of the proposed design is verified by the computer simulation. The simulation result shows that the modified die design for the progressive forming process can eliminate the crack and improve quality of the automotive bracket part.
