탄성충돌을 이용한 운동량 보존형 마이크로 펀치 시스템의 개발

초록

In this study, the momentum conservation type punching mechanism for micropunching system was developed to avoid the punch failure in the misaligned status between the punch and die. The punching energy can be precisely controlled by the falling height of the projectile mass and the intermediata mass, which contacts with the punch, transmit the energy to the punch with the same contact condition. The potential energy of the projectile mass is converted to kinetic energy at the light weight punch that the projection speed into the sheet metal workpiece can be accelerated. The burr formation characteristics for the alignment conditions and for the projection speeds are investigated to verify the feasibility of the proposed punching mechanism.
