汽车方向盘模具分型面的智能化设计

Intelligent Design of Automobile Steering Wheel Mold Parting Surface

摘要: 针对方向盘模具的设计中，其分型面人工设计花费时间较长，且较为复杂的问题，提出了一种基于分型线自动形成分型面设计方案。首先在方向盘上提取出完整的分型线，然后运用切割法将完整的分型线进行切割，将切割下的分型线通过弗雷歇距离相似度算法在曲线实例库中进行匹配，逐个成面，最终将各个离散面缝合为一个完整的分型面。基于UG二次开发，通过编程完成以上系统的设计，实现不同分型面的生成。实例表明，该分型面自动化系统能够极大提高生产效率，且生成的分型面符合加工要求。

Abstract: In the design of the steering wheel mold, the manual design of the parting surface takes a long time and is more complicated, a design scheme of automatic parting surface formation based on parting line is proposed. First, the complete parting line is extracted on the steering wheel, and then the complete parting line is cut based on the cutting method. The cut parting line is matched in the curve instance library by the Frechet distance similarity algorithm, and each discrete surface is stitched into a complete parting surface. Based on UG secondary development, the above system design is completed through programming to generate different parting surfaces. The example shows that the automatic parting surface system can greatly improve the production efficiency, and the parting surface generated meets the processing requirements.
