| Summary: | 碩士 === 國立虎尾科技大學 === 自動化工程研究所 === 103 === This research is focus on the patent analysis of procedure for electrical coiled silicon steel sheet in China Steel Corporation project. Servo punching machine its feature can change the speed of pressing and adjust the time series. In order to reach goal of multiplex function and change pressing speed of slow punching coiled silicon steel sheet. To improve its electromagnetic properties by using Vector Loop Method analyzing the motion of crank mechanism to obtain the punching speed via Newton''s second law of motion to analyze and read the operation condition on machine. For example, counter force from machine, transmit force from members, driving torque, motor power rate, etc. Experiment also use the time control on machine its reality parameter of max upper die weight, capacity and rated tonnage point, etc., combine the trimming motion curve. All the above analysis methods via Microsoft Visual Basic 6.0 to write an applied program to speed up the calculations and analysis and conclude its accuracy and the combing curves are appropriate. In the premise of change not the process speed, use servo control to slow down the punching speed and change the return speed to make the whole motor power down increasing the life of motor and also change the punching speed to control slider to fit more model of punching, for example punching, forging, extension and bending, etc.
