毕业设计（论文）二速轮锻模和切边冲孔复合膜设计.doc

黄河科技学院毕业设计说明书 第 PAGE 35 页 二速轮锻模和切边冲孔复合膜设计 摘 要 现代工业的迅速发展使模锻技术得到越来越广泛的应用，对锻模的设计与制造的要求越来越高。由于锻造模具是模锻生产的主要工艺装备，所以其设计是否合理，对模锻件的表面质量、尺寸精度、生产率以及经济效益等影响很大。因此提高锻造模具的设计水平和锻造模具的各项技术指标，对现代模锻工业的发展是十分必要的。 汽车、拖拉机以及矿山机械上关键零件都需要锻造制坯。以汽车为例，锻件占零件总量的85%以上。所以学习锻模设计具有很高的实用价值。锻件在生产过程中，一般需要成型和切边冲孔。切边冲孔复合膜较连续模具有效率高、质量好，减少设备台数等优点，所以被广泛使用。 本次设计目的就是针对二速轮的锻造设计，其中包括模锻和切边冲孔两大步骤。切边冲孔是锻件生产过程中的后续工作，可是所占时间远比模锻工序长。通过设计可以更好的了解锻造工艺，弥补在锻造方面的欠缺，也是对制造工艺的一个学习。 关键词：模锻,工业,切边冲孔,工艺 Two speed wheels and trimming punching composite film forging die design Author：Zhang Qiang Tutor：Li Qi De Abstract The rapid development of modern industry to die forging technology to get more and more extensive application in the forging die design and manufacture demand more and more. Due to the forging die forging is the main production technology and equipment, so its design is reasonable, forged pieces of the surface quality, size accuracy, the productivity and economic benefits of influence. Therefore improve design level of forging die forging die and the technical indexes , the modern die forging the development of industry is very necessary. Automobiles, tractors and mining machinery on the key parts of the need to forging blocking. To cars for example, forgings parts accounted for over 85% of the total. So study design is forging die high practical value. Forging in the production process, generally need to shape and trimming punching. Trimming punching composite membrane is continuous mould efficient tall, quality is good, reducing equipment sets etc, and so is widely used. The design purpose is in two of the wheel speed forging design, including die forging and trimming punching two steps. Trimming punching is in the process of forging follow-up work, but accounts for a long time than die forging process. Through the design can better understand the forging process, make up for the lack of in forging aspects, but also of the manufacturing process of a study. Key word
