A Rapid Parametric CAD System for Fine-Blanking Progressive Dies
Fine-blanking is an advanced and precision stamping process. Designing the construction die is an important part of the entire development process. But for lots of special and complicated structures of fine-blanking dies, especially some progressive dies, many problems occurred during the traditional two-dimensional design method, such as heavy workload, time-consuming, difficulty of modification, difficulty of checking interference, difficulty of novice entry. To solve these problems, a rapid parametric CAD system based on SolidWorks is developed for fine-blanking progressive dies in the present study. The system comprises five modules, namely DIEBASE, WORKPART, STANDARD, MOTION and DRAWING. The first three modules are designed for the rapid designing and modeling of three different sets of die components. These modules work in tandem with the design-table-based standard part libraries. The MOTION module is designed to simulate the movement situation and check the interferences of the die structure. The last module is designed for the drawing documents of the die parts and assembly. The main feature of the system is its parameter-based interfacing for fine-blanking progressive die design. The design and modification jobs could be done easily and quickly by operating this system, and the system is easy to learn for semiskilled and even unskilled engineers. An illustrative example is demonstrated to show the usefulness of the system.
