摘要我的毕业设计是纺机摇把摆杆冷冲压工艺与模具设计，冲压模具主要是将板料分离或成形而得制件的加工方法。因为模具的生产主要是大批量的生产，而且模具可以保证冲压产品的尺寸精度和产品质量，模具的设计与制造主要考虑到模具的设计能否满足工件的工艺性设计，能否加工出合格的零件，以及后来的维修和存放是否合理等。在本次设计的两幅冲压模具中，不仅要考虑要使做出的零件能满足工作要求，还要保证它的使用寿命。63242

其次设计中还要考虑到它的实际工作环境和必须完成的设计任务，模架采用后导柱式模架，导向精度较高，前后左右都可以进料，取放工件方便。在设计中我要考虑到很多关于我所设计模具的知识，包括它的使用场合、外观要求等，从这里可以知道模具设计是一项很复杂的工作，所以在设计要不断的改进直到符合要求。

Title    Cold stamping die design    

Abstract

My graduating design is a mold. Mold’s plate material is mainly obtained by separation or parts of the processing method of forming.  Because mold production is mainly large volume production,

And the products can ensure the dimensional accuracy and product quality, 

Mold design and manufacture the main consideration to the mold design process of the workpiece can meet the design,

Whether can it processes qualified parts,And subsequent maintenance and storage is reasonable or not ,and so on.

In this design, the two molds, not only to consider to make the parts made to meet the job requirements, but also to ensure that its service life. 

Second, the design should take into account its actual working environment and design tasks that must be completed,After using the guide pillar mold mold, oriented high accuracy, can feed around, pick and place convenient workpiece.

In this design ,I have to consider a lot about my knowledge of mold design, including its use of occasions, appearance requirements, from here you can know the mold design is a very complex task, so the design should be continously improved until it can meet the requirements .
