设计简介
摘要 本零件是针对冰箱压缩机底板零件进行冲压成型的模具设计，主要内容有：零件特点和工艺分析；成型工艺方案的制定、分析、比较；凸模结构设计；凹模结构设计；卸料装置设计；模架设计等。设计综合了大学三年所学的机械制图、材料力学、金属工艺、测量与互换、冲压工艺与模具设计、CAD、Pro/e等课程。本次设计直接应用了《冲压工艺与模具设计》、CAD、Pro/e的知识。由于该产品是结合压形、冲孔、翻边翻孔、切边成形的复杂零件,所以四个安装卡位精度要求高,其它模具结构尽可能简单。通过这次设计,我们初步掌握了模具设计的一般流程和方法，提高了综合知识的运用、计算机辅助设计实操和解决实际问题的能力。

ABSTRACT Parts of the refrigerator compressor against floor molding components for the stamping die design, the main contents are : Process characteristics and components; Process program development, analysis and comparison. Punch structure design; Die structure design; discharging device design; moldbase design. Integrated design of a three-year university studies in mechanical drawing, mechanical, metal crafts, measurement and exchange, stamping process and die design, CAD, Pro/e courses. The design of direct application of the "Die Stamping Technology and Design", CAD, Pro/e knowledge. Since the product was combined Pressing, piercing and flanging over the hole, trimming forming the complex parts Therefore, the installation of card-four high precision, the other mold structure as simple as possible. Through this design, we initially grasped the die design process and the general methods to improve their overall knowledge of the application Computer-aided design and practical operation of solving practical problems.
