轴瓦冲裁自动送料机构及模具设计
摘要:我的毕业设计是轴瓦冲裁自动送料机构及模具设计,主要涉及到冲孔落料复合模的设计。模具的生产主要是大批量的生产,而且模具可以保证冲压产品的尺寸精度和产品质量,模具的设计与制造主要考虑到模具的设计能否满足工件的工艺性设计,能否加工出合格的零件,以及后来的维修和存放是否合理等。在本次设计的轴瓦中,不仅要考虑要使做出的零件能满足工作要求,还要保证它的使用寿命。其次设计中还要考虑到它的实际工作环境和必须完成的设计任务,以及很多关于我所设计模具的知识,包括它的使用场合、选择合适的模具及送料方式等,从这里可以知道模具设计是一项很复杂的工作,所以设计要不断的改进直到符合要求。

The Design of the Bush Punching Automatic Feeding Machine with the Mold
Abstract: My graduation design is the Bush punching Automatic feeding machine with the Mold. The main concern is the design of posite modulus that contains the punching die and the blanking die. Because of large quantities production of the mold, either the mold can guarantee the high dimensional accuracy and its quality of product; the molds' design and manufacture must consider weather the mold ca
n meet the requirements of the work piece craft. Also must consider weather the mold can process the qualified part. Of cause, it also must consider weather the mold's service and store is reasonable. In the design of the bush, I not only should consider the parts can meet the job requirements, but also must ensure that its service life. Second in this design its actual work environment and plete design task should be consider. And a lot about the knowledge of the mould what I design. Including the use of occasion, choose right mould and its feed way. Here you can know that mold design is a plicated work. So it should continue to improve until meets the requirement

1 前言
随着现代化大工业的飞速发展,加上用模具加工成型产品具有生产效率高、产品质量稳定、互换性好、材料利用率高、操作简单、安全性好、工人劳动强度低、适用范围大、产品成本低等诸多优点,在电子、仪器、航空、汽车、摩托车、船舶制造、文化用品、医疗器械、日常生活用品及各种产品包装等生产行业中,均得到了非常广泛的应用[1]。很多产品中,有很多组成零件是用模具或经过模具制作出来的,其比例有的竟达到百分之八十以上。所以,模具已成为制造业不可缺少的重要组成部分。
背景
目前,我国在冲压工艺上与许多国家存在很大的差距。冲压的机械化和自动化程度较低。美国680条冲压线中有70%为多工位压力机,日本国内250条生产线有32%为多工位压力机[5],而这种代表当今的大型多工位压力机在我国的应用却为数不多。要改变当前大部分还是手工上下料的落后局面,结合具体情况,采取新工艺,提高机械化、自动化程度。争取加大投资力度,加速冲压生产线的技术改造,使尽早达到当今。同时改造国内旧设备,使其发挥新的生产能力。自动送料装置的
