【摘要】：汽车制造是一个国家制造业水平的重要的衡量标准之一,车身覆盖件的开发是车身开发的关键。覆盖件模具具有外形庞大、结构复杂、技术和精度要求高等特点,是汽车模具中技术最密集、加工难度最大的部分。相对于国外先进的覆盖件模具技术,我国除了少数龙头企业的覆盖件模具制造技术已经接近世界先进水平外,大多数的中小型企业的生产水平还相对落后,对于当前先进的基于项目管理和CAx/PDM的覆盖件模具开发方法还较为陌生。本文通过项目跟踪和总结,较为全面地介绍了国内先进车身覆盖件模具开发技术和流程,对项目管理、CAD、 CAE、CAM、CAPP、PDM等技术在模具开发中的应用做了总结,为进行覆盖件模具开发相关工作的人员和进行相关研究工作的科研工作者提供了参考。本文通过对山东潍坊福田模具有限责任公司某项目的项目范围管理、项目时间管理、项目成本管理、项目质量管理等项目管理的9个方面进行的跟踪与分析,确定了某项目中覆盖件模具开发过程的具体管理实施方案,保证了项目的顺利实施,展示了项目管理在提高效率、保证质量、降低成本等方面的重要性。本文对该项目中顶盖零件进行了冲压工艺设计,利用CAD、CAE、PDM等技术进行了零件的工艺分析,规划了工艺方案规划、零件成形过程进行了分析模拟,设计出了用于实际指导模具设计和生产的顶盖DL图。本文完成了该项目顶盖OP20修边侧修边模具结构的实际设计过程,解决了模具设计中的侧修、料渣、模具重量控制等重点和难点问题,进行了动态干涉检查、废料滑出模拟等校对评审工作,提出了一种利用UG表达式进行模具动态干涉检查的办法。最后,本文基于UG、PDM系统,进行了二维图纸的生成、属性表单的制作、明细表的生成填写等后续工序,并概括介绍了FMC实型制作工艺和CAPP零件加工工艺。
[Abstract]:Automobile manufacturing is one of the most important measurement standards of manufacturing level in a country. The development of body panel is the key of body development. The panel die has a large shape and complex structure. The characteristics of high technical and precision requirements are the most intensive and difficult parts of automotive die processing. Compared with foreign advanced panel die technology. In addition to a few leading enterprises in China, the manufacturing technology of panel die has been close to the advanced level in the world, and the production level of most small and medium-sized enterprises is relatively backward. For the current advanced project management and CAx/PDM based panel die development method is relatively unfamiliar. This paper through project tracking and summary. This paper introduces the domestic advanced automobile body panel die development technology and process, and CAPP for project management. The application of PDM and other technologies in die development is summarized, which provides a reference for the workers engaged in the related work of panel die development and the research workers involved in the related research. In this paper, the project scope management, project time management, project cost management, project quality management and other 9 aspects of project management of Shandong Weifang Futian Mould Co., Ltd are followed and analyzed. The concrete management and implementation scheme of the development process of panel die in a certain project is determined, which ensures the smooth implementation of the project and demonstrates the importance of project management in improving efficiency, ensuring quality and reducing cost. This paper has carried on the stamping process design to the middle top cover part of the project, has carried on the process analysis by using the CAD / CAE PDM and so on, has planned the process plan. The forming process of the part is analyzed and simulated, and the DL drawing of the top cover is designed to guide the design and production of the die. This paper has completed the practical design process of the top cover OP20 trimming side trimming die structure, solved the key and difficult problems in die design, such as side trimming, material slag, die weight control and so on. In this paper, dynamic interference check, waste slip out simulation and other proofreading work are carried out, and a method of mould dynamic interference inspection using UG expression is put forward. Finally, this paper based on the UGG PDM system, carried on the two-dimensional drawing generation, the attribute form production, the detailed list generation and filling out and so on follow-up procedure. The manufacturing process of FMC and the processing technology of CAPP parts are also introduced in this paper.
