基于UG的冷冲模造型设计系统

On the UG-Based Modeling Design System of Cold-Punching Dies

针对冷冲压模具CAD系统的标准化程度较低、专用性不强、开发手段落后等问题,研究了参数化造型与特征建模基本理论及基于UG的标准件建库方法.构建了基于UG的冷冲模造型设计系统,应用UG二次开发技术建立了冷冲模标准件库和标准模具库,运用"自底向上"的方法进行冷冲模的装配设计.在模具零件设计造型过程中采用了UG WAVE技术.通过某汽车零件落料模的设计实例,验证了应用此冷冲模造型设计系统对提高模具设计效率、加强模具设计标准化具有重要意义.

Current CAD system of cold-punching dies has some problems such as low degree of standardization, weak specificity, behindhand development tool and so on. The basic theory and methods of parametric design and feature-based modeling were thus investigated to develop a UG- based modeling design system for cold-punching dies. With the secondary development tools of UG used, the libraries of both standard parts and common dies were framed, by which the assembly design of any cold-punching dies is available to be completed according to the bottom-up design method. The UG WAVE technology is applied in the modeling process of die parts. Exemplifying the design of a blanking die for car parts in a certain car manufacturer, the modeling design system for cold-punching dies is of significance to improve the efficiency of die design and standardize it.
