基于参数化关联技术的冲裁模具设计研究

对于相似性零件冲压模具重复设计和零件更改造成的模具重新设计的问题,参数化关联技术是主要的解决途径之一.本文研究了参数关联的理论和方法,研究了参数的传递的方法,以冲裁模具的设计为例,介绍了冲裁模具参数化关联技术的具体实现,并应用CATIA二次开发方法进行基于参数化关联技术的冲裁模具设计.实现了冲裁模具的快速设计,在设计依据发生更改时模具设计能够随之进行快速更新,从而提高了设计效率.

Study of blanking design based on parameterization-associated technology

Aimed at the problem of the blanking die redesign and similar workpieces repeating design, the parameterization-associated technology is one of the main solutions to reducing redesign The theory and methodology about parameterization-associated technology are researched, and the method delivering param- eters is introduced. By illustrating the design of a blanking die, this paper presents the realization of the pa- rameterization-associated technology, carries out a blanking die design based on both parameterization associ- ated technology and the secondary development of CATIA method. Not only will the rapid design system of blanking dies develop, but as the design database changes, accordingly, the blanking die is rapidly updated, which, as a result, will raise the working efficiency.
