The Research And Design Of Polyimide Film Punching Machine

Polyimide punching machine is a kind of punching equipment to processing polyimide film, which has been existed for 40 years and widely applied to the field of space flight, military, electrical appliances, etc. because of the excellent properties of it. Recent years, polyimide film has been widely used in satellite, and with the rapid development of aviation field, the requests for processing will increasingly improved.Although punching machine has been existed in our country and abroad, they are not suited for polyimide punching processing and they are very expensive. As a result of that, it's necessary to develop polyimide punching machine. After entering WTO, in the face of the challenges of a lot of advanced technology from developed countries in the world, it is urgent to develop mature technology and products according to China's market demands.In this paper, we discussed the working principles of punching machine. Then aimed at improving the efficiency and reliability, its pneumatic system is designed. According to theory analyzing and different design criteria, the structure such cylinder and other components are designed. According to the analysis of the electric control system, the mathematical model is built.The concrete research contents are as follows:we explains the significant importance of developing polyimide punching machine, as well as the main research contents of the thesis.To proposes the design requirements for polyimide punching machine on the basis of analysis of demanding, and put forward overall design plan for it.Combining advanced study the mechanical mechanical design theory with some relevant knowledge to transmission system of the machine, and have accomplished designing of system, framework structure and transport system.The paper covers the design of control system and carries out the selection of electricalparts based on practical demand and safety.To build the model of main control system.At last, provides the summary of the whole paper and developing future.This paper has solved the key problem of using mechanical punching for polyimide film. This technology has brought great conveninece and direct economic benefit for the aviation field, enhanced the aviation of our conutry internotional competitive ability, also enable the punching technology to have the wider use space.
