机制专业毕业设计 PAGE 42 冲压模具毕业设计 摘 要 模具生产的工艺水平及科技含量的高低，已成为衡量一个国家科技与产品制造水平的重要标志，它在很大程度上决定着产品的质量、效益、新产品的开发能力，决定着一个国家制造业的国际竞争力，因此这次我们的设计要求设计一个模具以便检验自己所学模具有关方面的知识是否牢固。 在这次设计中根据所给题目的要求，我首先对冲压件进行了分析，分析该零件的尺寸精度得出用一般精度的模具即可满足零件精度的要求，再从零件的形状、尺寸标注及生产批量等情况看，我选择了以下方案。 根据对零件的综合分析，在本人这次设计中我设计的模具是落料模，主要介绍的是模具的冲裁，冲压生产中应用最广泛的工序之一。材料为30钢板，厚度t=0.3mm。传统的加工方法为落料。我的加工方法比较简单。由于材料和厚度的原因，我采用的加工方法为：采用单工序落料模进行加工。 关键词：落料模； 冲裁； 冲压模具 Stamping mould graduation design Abstract Mould manufacturing technology level and the content of science and technology, has become a national science and technology and product manufacture level of important symbol, it largely determines the quality of products and the benefit, the new product development capabilities, a country depends on the international competitiveness of manufacturing, therefore, we design a mold design requirements to test their knowledge about whether the knowledge of mould. In this design according to the topic request, I was the first to stamping is analyzed, the analysis of the components of the dimension precision mould with general accuracy that can meet the accuracy requirement of the parts from the shape of the parts, and the production batch, dimensions, as I chose the following solutions. Based on the comprehensive analysis of the parts, in the design of my I design, mold is dropping material is mainly introduces the cutting, stamping mould manufacturing processes in one of the most widely used. Materials for 30 plates, thickness t = 0.3 mm. The traditional processing method for blanking. I processing method is simple. Due to material and thickness of reason, I used for processing methods: the procedure blanking process mode. Keywords: blanking, Cutting, Stamping mould 目 录 TOC \o 1-4 \h \z \u HYPERLINK \l _Toc262067511 1.前言 PAGEREF _Toc262067511 \h 5 HYPERLINK \l _Toc262067512 1.1 模具在现代化工业生产中的地位和作用 PAGEREF _Toc262067512 \h 5 HYPERLINK \l _Toc262067513 1.2 我国的模具工业状况 PAGEREF _Toc262067513 \h 8 HYPERLINK \l _Toc262067514 1.3 模具工业技术
