摘 要
下料机是一些轻工行业不可缺少的设备。传统观念，下料机是借助于机器运动的作用力加压于刀模，对材料进行切割加工的机器。近代的下料机发生了一些变化，开始将高压水束、超声波等先进技术用于皮革冲切技术中，但人们仍然将这些设备归纳在下料机类的设备中。
本课题的设计目的是巩固机械设计专业有关机构和机械设计的知识，对机械系统设计的有关知识得到强化；在设计中学习下料锯的工作原理和组成部分并对其进行设计；同时在设计中要求以二维图的形式表现出设计思想，所以对Auto CAD的掌握和运用得到进一步的提高，培养自己运用建Auto CAD设计零件和产品的意识和能力。
通过这次毕业设计培养自己实事求是的学习态度和刻苦钻研的好学精神；培养理论联系实际的能力，树立正确的设计观和科学研究观，养成严谨务实的科学和科研作风；锻炼自己运用综合知识解决问题、翻译外文资料和查阅资料的能力。

ABSTRACT
Cutting machines are indispensable equipment in light industry. Traditional concept of the machine cutting machine by means of force pressure on the knife mold movement, the material cutting machine. Modern cutting machines have been some changes and began to high-pressure water beam, ultrasonic, and other advanced technologies for leather cutting technology, but people still will summarize these devices like the next feeder device.
The project is designed to consolidate the mechanical design and mechanical design of the relevant bodies of knowledge, the design of mechanical systems of knowledge have been strengthened; in the design of learning material saw under the working principle and integral part of its design; the same time in the design requested in the form of two-dimensional map showing design ideas, so the master and use Auto CAD to further improve and develop its own design using Auto CAD building components and product awareness and ability.
Develop their own graduation through this pragmatic attitude and hard study to learn a love of learning; develop theory with practical skills, foster a correct view of the design concept and scientific research, to develop a rigorous and pragmatic style of scientific and research; exercise their comprehensive knowledge of the use of solve the problem, translate foreign data and data access capabilities.
