《轮盘冲压成型工艺与模具设计》-毕业论文.doc

PAGE 摘 要 冲压模具在实际工业生产中应用广泛。随着当今科技的发展，模具已经越来越多地被应用到工业生产中来。冲压模具可以大大的提高劳动生产效率，减轻工人负担，具有重要的技术进步意义和经济价值。 冲压工艺是一种生产效率很高的、少切屑或无切屑的先进加工方法，在经济和技术方面都有很多的优点。冲压工艺按其变形性质可以分为材料的分离和成形两大类，每一类中包括许多不同的工序. 本次设计的零件为轮盘冲压，所用材料是Q235。本论文分析了该工件的成形工艺，计算了该工件的毛坯形状尺寸及各工序尺寸，并在此基础上确定了合理的冲压工序，分为三道工序分别为工序一落料和拉深，工序二冲孔腰形孔，工序三内外缘翻边。此方案的特点是模具结构简单，制造成本低，操作方便，并且尺寸和精度达到工艺要求，具有良好的性价比。 本设计工序采用曲柄压力机进行冲压，具有生产效率高、维修简单、工作环境整洁等特点。本文模具进行模具结构的分析，主要零件的设计和模具的经济分析，并且详细介绍了设计方法和步骤。 关键词： 冲压工艺；模具设计；曲柄压力机；复合模 Abstract Punching dies was used widely in industrial production applications. With todays technology development, mold has been an increasing use of industrial production. Punching die can greatly improve labor productivity and reduce the burden of the workers, further more it has important technological progress and economic value. Punching process is a high production efficiency, no or less process methods, in the economic and technical aspects which has many advantages. The essential procedure of Punching are separating and shaping, each category includes a number of different processes. This design components is wheel plate ,the material of wheel plate is Q235. In the paper, the molding technology of the stainless steel drawing part was analyzed, the dimensions and shape of the blank were calculated, the drawing times and dimensions of the part were determined and made sure on this foundation reasonable of hurtle and press the work preface is divided into three working procedure difference as the first working procedure is blank and elongating, the second working procedure is the work preface four slice the side and pressing the raised package , the third working procedure is piercing .The characteristics of this project is the molding tool structure simple, the manufacturing cost is low, operation convenience, and the size and accuracies attain the craft request, having the low price and well quality to compare. The design procedure adopts the crank pressure machine to press the parts. Because
