【摘要】 本文进行了模具标准件数据库、冲压过程动态仿真和模具的机械电解复合抛光技术两方面内容的研究。模具标准件数据库和冲压过程动态仿真的研究针对模具的结构复杂性、各个运动零件之间的易干涉性,以及模具设计中需要用到大量的标准件;针对当前我国一大部分飞机、汽车企业都在使用CATIA软件这一状况,我们和哈飞汽车模具制造有限责任公司合作开发基于CATIA的冲压模具参数化数据库及动态仿真的研究。本文探讨了三维参数化的方法,以CATIA V5软件为二次开发平台,利用VB6.0开发语言,采用数据库管理参数化数据和模型图,开发了模具参数化标准件数据库,实现了三维标准件的自动生成。统一的可视化图形界面,方便了用户的使用。利用CATIA V5的装配和仿真模块,研究了冲压模具的合理装配和仿真技术。模具的机械电解复合抛光技术的研究针对难加工材料曲面的模具,依据电解理论,结合CAD/CAM自动化技术,提出机械电解复合模具抛光的新型工艺方法,在数控机床上进行巴氏合金模具曲面的抛光, 取代了传统的手工研磨方法, 从而提高了模具的加工质量和加工效率,并解决了巴氏合金材料的抛光问题。通过实验分析表明,该工艺可提高抛光效率,容易降低巴氏合金模具表面粗糙度。更多还原

【Abstract】 In this paper two contents are studied: the data library of mold standard parts, dynamic simulation of the punching process and the mold’s mechanical-electrolytic polishing. Study of the data library of mold standard parts and dynamic simulation of the punching processAiming at the complexity of mold structure、the interference between every motional parts, and a lot of standard parts to be needed during mold designing, and the CATIA software is used in a big part of airplane and automobile enterprises. We cooperatively studied the data library of mold standard parts and dynamic simulation, with Hafei Motor Die Manufacturing Co. Ltd.In this paper the method of three-dimension parameterization is studied and the parameterized data library of mold standard parts by using VB6.0 developed language based on the secondary development platform-CATIA V5 is developed. The system manages the parameterized data and model drawings adopted data library. The unitive visual graphical interfaces are used conveniently by users. We also studied the technology of assembly of reasonable and the mold simulation with the help of CATIA V5.Study of the Mechanical Electrolytic Polishing Mould Aiming at problems of polishing the difficult-machining-material mould with curved surface, according to the electrolytic theory, the new process of combining mechanical and electrolytic polishing with CAD/CAM technology is presented. The Babbitt metal mould cavity is polished on the numerically controlled machine tool, in stead of the traditional manual process. So the processing precision and efficiency <WP=7>are improved, and the problem of polishing Babbitt metal are resolved. The analysis indicates that the efficiency is improved and the roughness of mould can be reduced with ease.更多还原
