Question

谁来帮我翻译一下！！！急！！！谢谢~~~

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。通过查阅大量相关文献资料，参考模具设计类手册，对接触片零件进行工艺性分析，并且选择能够符合零件要求的最佳方案。从选择模具类型到确定其基本工序、工序数目、模具的总体结构设计。还应用了在级进模中利用侧刃和导正销来实施送料定位并同时对冲裁件的外形轮廓进行成形冲切的设计。给出了在模具设计过程中所需要的必要的计算过程，其中包括了：确定排样图时需要的步距及条料宽度、选择压力机时需要的冲压力及压力中心的计算、凸凹模刃口尺寸的计算，并且绘制出模具装配图和非标准件零件图。同时还把平时学到的理论知识与生产实际知识想结合，巩固并完善了模具专业类的知识。最新接触到的就是凹模采用了镶件结构，这样有利于生产过程中模具的换模、维修、保养，从而使得功过效率大大提高。通过整套模具的设计，使我自己的计算能力，计算机绘图能力有所提高，也熟悉了很多标准件的选择方法。

The graduation design task is to contact pieces parts stamping process analysis and mold concrete structure design. Through consulting a number of literature material, reference mould design for contact pieces of manual, parts, and choose usability analysis could meet the best scheme. Parts requirements From selecting mould type to determine its basic processes, and process the overall structure of the number, mould design. Still applied a progressive die by the side of the blade and guide are pin to the implementation of the positioning of feeding and also the appearance of cutting piece hedge for forming punching outline design. In the mould design process are needed in the calculation process of necessary, including: determine the strip layout drawings for the need to step distance and strip material width, selection pressure machine needs pressure and pressure center rushed calculation, the size of the blade die and punch, and draw out of the mold calculated the standard parts drawing drawings and. Also learn the ordinary theoretical knowledge and practical knowledge production to consolidate and perfect combination, the die professional such knowledge. The latest touch is concave die adopt a set piece structure, like this is advantageous to the production process mould changing mould, maintenance, maintenance, thus make the merits and the efficiency is greatly improved. Through the package of mould design, make my own computing skills, improve computer graphics ability, also familiar with a lot of standard selection method.
