According to the differen ce between the size of into - wire diameter and outlet - wire diameter, the drawing machine can be classifi ed asr ough stretch ing machine and precise drawing machine . This paper involves the algorithm theory and the electric control body for the practical process It concludes the synchronous running principle of LZ-4/670 straight wire machine reels and the calculation method of rotation speed ratios among reels. The force for steel wire drawing , the output torque of motor and the output torque of reels are calculated in detail. The speed regulation principle of frequency converter for the machine. , the electro control principle and the setting upof parameters are expounded . This article are fitted with the detailed hardware structure and the software ’f low chart . Key words : straight wire drawing machine, reel ’s synchronous operation, speed regulation with frequenc y 目录 III 目录摘要......................................................................................................................
