Multi-Point Dieless Sheet Forming Technology Combined with Fluid forming
유체성형과 결합한 다점 무금형 판재 성형기술
Abstract
A new concept of dieless sheet forming technology is proposed in this study to overcome the drawback of conventional dieless forming technology. For this purpose, dual points contact of the conventional punch system, which is a primary cause of surface defects, is replaced to single point contact using technology combined with fluid forming. It is expected that the advanced system may lead to easy displacement control of multi-punch elements, reducing surface defects, and increasing decision and forming limits. The reduced number of punch elements also saves the cost of the equipment. In addition, the new technology can be utilized for deep drawing as well as two- or three-dimensional curved surface forming, and thereby become multi-functional and multi-purpose differently from the conventional technology.
