支架零件冲压工艺及冲模设计
摘要: 模具是制造业的重要工艺基础，模具制造属于专用设备制造业。模具技术集合了机械、电子、化学、光学、材料、计算机、精密监测和信息网络等诸多学科，是一个综合性多学科的系统工程。模具技术的发展趋势主要是模具产品向着更大型、更精密、更复杂及更经济的方向发展，模具产品的技术含量不断提高，模具制造周期不断缩短，模具生产朝着信息化、无图化、精细化、自动化的方向发展，模具企业向着技术集成化、设备精良化、产批品牌化、管理信息化、经营国际化的方向发展。
 本次设计一套冲空、落料的模具。经过查阅资料，首先对零件进行工艺分析，经过工艺分析和对比，采用冲孔落料工序，通过冲裁力、推料力、卸料力等计算，确定压力机的型号。再分析对冲裁件加工的模具适用类型选择所需设计的模具。得出将设计的模具类型后将模具的各工作零部件设计过程表达出来。在说明书的第一部分，主要叙述了冲压模具的发展状况，说明冲压模具的重要性与本次设计的意义，接着是对冲压件的工艺分析，完成工艺方案的确定。第二部分，对零件排样图的设计，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算。通过前面的设计方案画出模具各零件图和装配图。

 The support components ramming craft and dies the design    
Abscract: The mold is the manufacturing industry important craft foundation, the mold manufacture belongs to the special purpose equipment manufacturing industry. The mold technology has gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendency mainly is the mold product to larger-scale, preciser, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the automated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops.
This time designs a set to flush spatially, falls the material the mold. After the consult material, first carries on the process study to the components, undergoes the process study and the contrast, uses the punch holes to fall the material working procedure, through the blanking force, pushes computations and so on material strength, ex-denning strength, definite press's model. The analysis is suitable the mold which again to the blanking processing's mold the type choice must design. After obtaining mold type which, will design expresses mold's each work spare part design process. In the instruction booklet first part, mainly narrated the ramming mold's development condition, explained that the ramming mold's importance with this design's significance, is to pressing part's process study, completes the craft plan the determination. The second part, to the components row of specimen map's design, has completed the material use factor computation. Carries on the blanking craft strength again the computation.
