CNC Winding Machine Control Of Process Parameters Method

NC cloth winding machine is special equipment that wind SRM's nozzle and prats of bearing ablation, heat protection, missile cone, emitter and astro navigation aircraft parts with bakelite. The west developed industrialized countries embargo blockade the technic of NC winding machine tightly. This equipment is prerequisitly needed craft equipment for research and production of aerospace industry in our country. Therefore, the study of new type, multi-axis, multi-functions, control of multi-parameters for abnormity parts and control software and matching craft parameter are urgent affairs. For breaking abroad embargo blockade, the author study advanced multi-functions NC cloth winding machine own intellectual property.This project rooted from contract that signed with one academic institute in Shanghai Multi-functions NC cloth winding machine integrate mechanics, electronic, gas, control, software and numeric control technic. The research is a complex project. After studying the Composite material molding, the author research tension, temperature, press that affect the productions' quality, and put forward applied closed-loop control project, and add the auto-measure function. These enhance the machine's reliability and perfect machine's functions.With development of the control and hardware technic, all kinds of special controller are produced. Their control precision and reliability are tested by practice, and are used to control the parameters of multi-function NC winding machine completely. Author makes full use of mature technical controller and algorithm.Author puts forward new type tension equipment, and improved the accuracy that tension measures, and afford condition for control. For increasing the real-time of software, author use hardware controller to fulfill control of tension and temperature. Industrial computer take on watching and displaying parameters. Cylinder is executing element of air pressure system. Proportional valve is the control element. A dynamic integral separated PID algorithm control press. Author developed auto-measure based on SIEMENS NC successfully.The research result are applied in winding machine in Shanghai. After checkout, the machine wind accord with request product completely. The user extremely satisfies regarding this.
