毕业论文-子午线轮胎模具设计.docx

济南大学泉城学院毕业设计-- I 摘要模具在工业生产中基础工艺设备,使用十分广泛,是国民经济的基础。随着中国经济的日益发达和国际整体大形势的前进,汽车的普及越来越广泛,各种类型的车辆层出不穷,数量也爆炸式增长,轮胎作为汽车上最易消耗的物品之一,轮胎的制造越来越重要。轮胎质量的好坏将直接影响车辆的通过性、安全性、速度、动力、油耗等要素,而模具的使用和制作将直接决定车辆轮胎的外形,所以,制造模具的质量与工艺就显的十分重要。由于现代车辆轮胎对模具的要求越来越高,所以传统的制造模具的方法已经不能够满足模具生产的需要,在此情况下就促进了 CAD/CAM 技术在模具制造业中广泛的应用, CAD/CAM 技术是先进模具制造技术的基础和重要的组成部分,发展方向正在集成化、网络化、智能化等现代制造业方向发展。在模具厂逐渐增多,压力逐渐增大的情况下,模具行业如何提高模具的质量成为了最主要的问题。模具制造流程的规范化,以及工艺标准化已经是大势所趋的事情, 只有制造流程与工艺有了一定标准后,才不会出现同一规格型号轮胎有略微差别的情况,因为我们知道,如果一辆汽车四个轮胎的差别超出了一个度,那么在汽车安全系数等方面是很危险的。因此我们必须要制定统一的流程化、标准化,这是一个很有必要的生产过程。课题首先对现在十分流行的 CAD/CAM 技术及优点进行了简单的介绍,而 UG 软件正是 CAD/CAM 软件的代表, UG 具有三维造型、机构分析、工程制图、仿真动画等许多强大功能,所以本文对 UG所具有的功能,以及在模具制造中的应用进行了研究和分析。并在最后分别介绍了在 CAD/CAM 技术下模具制造的三大块,结构、花纹以及刻字。关键词: 轮胎花纹;侧板刻字; CAD/CAM 技术;轮胎结构;模具装配济南大学泉城学院毕业设计- II- ABSTRACT Die in the industrial production base of process equipment, is widely used, is the foundation of the national economy. With the Chinese economy and the international situation of overall progress, the popularity of the car is more and more widely, various types of vehicles have explosive growth emerge in an endless stream, the number of items on the car tires, asone of the most easy to use, and tire manufacturing more important. Tire quality will directly affect the passage of vehicles, safety, speed, power, fuel consumption and other factors, and use and mold production will directly determine the vehicle tire shape, so the quality and process of mould manufacturing is very important. Because the modern vehicle tire The mold of the increasingly high demand, so the traditional mold manufacturing method has not been able to meet the needs of mold, in this case on the promotion of CAD/CAM technology is widely used in mold manufacturing industry, CAD/CAM technology is the basis of advanced manufacturing technology and an important part of the development direction are integrated, networked intelligent, modern manufacturing industry development direction. Gradually increased in the mold factory, the pressure grad
