Study on CAD system for fine-blanking dies based on SolidWorks

Aim at some problems of the traditional methods occurred during fine-blanking die design, such as heavy workload, difficulty of design modification, inconsequeence die structure and no support for interference check, a three-dimensional CAD system for fine-blanking dies based on SolidWorks was developed. The systematic developing method and some key technologies for CAD system of fine-blanking dies were presented, including parametric modeling, design table-based standard parts library managerment and knowledge-based stamping process planning and die structure design. The overall structure of developed CAD system was established, and the practicality and advancement of developed CAD system for fine-blanking dies were proved by some examples.
