摘 要
本课题是根据目前我国旋锻技术的发展现状而进行的数控旋锻机床的设计与研究。 由于现代科学的发展，对产品的质量提出了更高的要求。从而对机床的要求也就有的更加的要求 ，传统的加工工艺生产效率低，并且精度不能保证[1]。但是数控旋锻机采用了闭环系统，自动进行插补运算，改变了传统开环系统形式，通过电气与液压系统有效配合，大大提高了旋锻机的使用性能。现代机械制造中加工机械零件的方法很多：除切削加工外，还有铸造、锻造、焊接、冲压、挤压等，但凡属精度要求较高和表面粗糙度要求较细的零件，一般都需在机床上用切削的方法进行最终加工。机床的进步反映了一个国家的工业化进程水平。而特种数控旋锻机床作为具有先进制造技术的基础制造装备,已被广泛应用于航天、航空、能源、交通等各个领域,其加工精度、加工效率和加工能力的高低直接影响着一个国家国民经济和国防建设的发展。论文研究对象是一种德国进口并可进行旋转锻造加工的多功能特种数控机床，目前国内并无此种设备的研制和生产。本论文正是对此种机床的结构进行分析并进行主体机床结构的仿制、改进和设计。研究中应用先进设计手段辅助机床结构设计，利用SolidWork软件进行机床三维布局及造型设计，机床的设计效率和设计过程可视化程度都得到较大提高。论文研究除完成了数控旋锻机床结构的主体设计，论文中还运用有限元分析软件,对机床使用的模具进行动态受力分析。论文还对数控旋锻机床的模具和主要零部件的制造和修整做了较详细的介绍，对数控旋锻机床的检修和保养方法也做了说明。希望在借鉴和学习国外先进机床制造技术的情况下，能对国内特种机床的发展和进步提供一些资料和参考.

Abstract
The issue is the design and research of CNC rotary forging machine according to the current development status of swaging techniques carried out. Due to the development of modern science, the quality of the product a higher requirement. Thus some of the requirements of the machine will be more demands, low productivity of traditional processing technology, and accuracy can not be guaranteed. But CNC rotary forging machine uses a closed-loop system, automatic interpolation operation, changing the form of the traditional open-loop system, electrical and hydraulic systems through effective coordination, greatly improving the performance swaging machine. Mechanical machining methods of modern manufacturing many mechanical parts: Cutting addition, there are casting, forging, welding, stamping, extrusion, etc. Where the higher accuracy but the required surface roughness and fine parts, generally takes final processing methods on the cutting machine. Machine progress reflects the level of a country's industrialization process. The special CNC rotary forging machine as the basis for manufacturing equipment with advanced manufacturing technology, has been widely used in aerospace, aviation, energy, transportation, and its precision machining, processing efficiency and the ability to directly affect the level of a country's economy and the development of national defense construction. Thesis is a study of German imports and can be rotated forging special multifunctional CNC machine tools, there is no domestic development and production of such equipment. This paper is to analyze the structure of such a machine and copy machine body structure, improvement and design. Research in the application of advanced design tools assist machine design, the use of software tools SolidWork dimensional layout and design, machine design efficiency and process visualization have been greatly improved. In addition to the completion of the main thesis of CNC swaging machine structure design, the paper also uses finite element analysis software tools used to mold the dynamic mechanical analysis. The paper also manufacture and repair of CNC machine tools swaging dies and major components to do a more detailed introduction to CNC swaging machine repair and maintenance methods also made instructions. In the case of hope to learn from foreign advanced machine manufacturing technology, capable of national progress and development of special tools provide some information and reference
