接触片落料冲孔级进模 毕业设计/毕业论文/课题报告 - 模具设计类

摘要
本次毕业设计的任务是接触片零件冲压工艺分析和模具的具体结构设计。通过查阅了相关文献资料，对接触片零件进行工艺性分析，选择并确定符合于给定条件的最优工艺方案，及进行了工艺与设计的有关计算，如：选择基本工序，确定其顺序、工序数目及工序组合形式。介绍了主要零部件的设计理念，详细剖析了设计过程中一些思路，以及某些非标准零件的使用特点。阐述了工位级进模的设计要点, 使产品质量达到设计要求。然后以此为基础，设计出冲压模具主要零件的结构。并在设计中，介绍了零件的排样图、定位设计、冲裁力的计算和压力中心的计算。
分析了冲模模架的基本类型，讨论了冲模模架的技术要求，介绍了标准模架的装配工艺。并指出了模架装配时的注意事项。条料的步进定位是一个很重要的工序，其对工件的精度影响很重要，因此对其设计的准确性与标准性对模具既有利于模具维修的规范化，也为整个模具的顺利生产打下了一个良好的基础。同时凸、凹模结构对产品生产质量影响也很大，在提高经济效益和降低成本的前提下，设计出合理而简单的凸、凹模结构是设计中的重要环节。

Abstract:
The design is focus on both the analysis of Pressing technics of the contact plate and the particular configuration design of die. According to check with a great deal of reference details .It is a must to base on the technical analysis of the patch, then choose a best craft procedure to a given project. For instance, basic procedure's choosing, basic procedure's sequence confirmation , the amount of the working procedure and the format of the procedure combination. Presentation of the main components of the design concept, a detailed analysis of the design process in a number of ideas, as well as the use of certain features of non-standard parts On-position progressive die design features, so that the quality of products meet the design requirements. And then as a basis for designing the main parts stamping die structure. And design, introduced the nesting parts map, location design, the calculation of punching force and the calculation of center of pressure. [来源：http://www.think58.com]

Analysis of the die of the basic types of mold, die mold discussed the technical requirements on the standard mold of the assembly process. And pointed out that when the mold assembly of attention. Be expected to step positioning is a very important process, and its impact on the accuracy of the workpiece is very important, so the accuracy of their design on the mold with the standard of maintenance of both the standardization of mold, but also for the smooth production of the mold and lay a good foundation. At the same time, convex, concave mold structure of the product quality of a great impact in improving the economic efficiency and reduce costs under the premise of the design of a reasonable and simple, convex, concave mold structure is an important part of the design.
