拉手卡子零件冲压模具设计 学生姓名： 周勇奇 班级：0681053指导老师： 罗海泉摘要：由于模具工业的重要性,模具成型工艺在各个工业部门得到了广泛的应用,使得模具行业的产值已经大大超过机床刀具工业的产值.这一情况充分说明在国民经济蓬勃发展的过程中,在各个工业发达国家对世界市场进行激烈的争夺中,越多越多地采用模具来进行生产,模具工业明显地成为技术 经济和国力发展的关键.因此,要使国民经济各个部门获得高速发展,加速实现社会主义四个现代化,就必须尽快将模具工业搞上去,使模具生产形成一个独立的工业部门,从而充分发挥模具工业在国民经济中的关键的作用.本论文阐述的是拉手卡子零件冲压模具设计，冲压模具主要包括冲裁模具、弯曲模具、拉深模具、多工位级进模、简易冲模等。本课题的主要任务是完成拉手卡子落料冲孔复合模及弯曲模的设计，具有非常现实的设计意义。复合模是在压力机的一次行程中，在同一工位上完成两道或两道以上的冲压工序。复合模的结构紧凑，冲出来的精度高，适合大批量的生产，但复合模的结构复杂，制造相对困难。本设计拉手卡子零件冲压模具，凸凹模安装在模具下模座上。倒装复合模废料清理无须二次清理，操作方便安全，生产效率较高。复合模与弯曲模的设计过程大致相似，复合模较弯曲模结构更为复杂。设计上主要是对凸模、凹模和凸凹模的设计，其中主要是其工作部分的尺寸设计，以保证制件的精度和质量要求。关键词：冲压模具 工艺分析 复合模 弯曲模 指导老师签名： Certain automobile element stamping technology analysis and mould designStudent name: zhou yong qi Clss:0681053Supervisor: Luo Hai QuanAbstract: as the importance in the industry of the mould , the shaping craft of the mould is widely used in each industrial department, which makes the output value of the mould trade already exceed the output value of the industry of the lathe and cutter greatly. This situation is fully explained while national economy is vigorous, carry on the world market in fierce contention in each industrially developed country, more and more will adopt mould produce, mould obviously become the key of technological, economy and, national power of development with industry.So, to make each department of national economy win high-speed development , realize the sociality Four Modernizations with higher speed, it must develop the industry of the mould as soon as possible , make the mould production form an independent industrial department, thus give full play to the key function in national economy of industry . What this paper explained is pressing craft analysis and mold design of an automobile ear slice, press mould mainly including blanking mould , crooked mould , draw dark mould , many worker location grade enter mould , simple and easy trimming die ,etc. What this text explains is mainly about a slice of blanking of automobile ear washes hole complex model and crooked model design, which have very realistic design meanings. The complex mould finishes two or two processes of pressing of the above on the same workers location in a journey of the press. The structure of the complex mould is compact, the precision washed out is high, suitable for the production in enormous quantities, especially hole and concentricity of making appearance of one are apt to guarantee , but the structure of the complex mould is complicated, make relative difficulty. Originally design the slice of automobile ear complex mould of hole adopt the structure of inverting, protruding concave mould installs it on the mould seat of the mould. Inverting the complex mould waste material neednt clear up twice, easy to operate and safe and the production efficiency are relatively high. The design process of complex mould and crooked mould is roughly similar; while the complex mould is more complicated. It is mainly to protruding mould, concave mould and the protruding concave models design, among them that it is mainly design some si
