基于Pro/E软件的仿形靠模轮廓曲线设计与运动仿真

THE DESIGN OF PROFILE CURVE AND MOTION SIMULATION OF PROFILING MOULD BASED ON PRO/E SOFTWARE

设计仿形靠模轮廓曲线常用方法有作图法与计算法。计算法过程烦琐,需要计算机辅助编程完成,而传统作图法又具有误差大、精度不高的问题。以某一生产零件为例,利用Pro/E软件将作图法融入其中获得仿形靠模理论轮廓曲线的坐标,并生成较高精度的仿形靠模理论轮廓曲线及其实体,提高了仿形靠模的设计精度与效率。实践证明,这是一种有效的方法。

By the common method of profiling mould the design curve mode contour mapping method and calculation method. Calculation process is cumbersome, require computer-aided programming is complete, and the traditional mapping method also has the error, the accuracy is not high. In this paper, some production parts, for example, the use of Pro / E software will get into them by copying mode theory contour curve mapping coordinates, and generates high precision contoured cam profile curve theory and its entities to improve the profiling by mold design accuracy and efficiency. Practice has proved that this is an effective method.
