Abstract: In order to solve the needle in the highspeed drawing tension control problem, automatic control technology was applied to the drawing machine. Detailed description of the structure and mechanical drawing machine theory, analysis of the relationship between detection and control, and needle tension during drawing process changes, PID servo control was proposed to achieve rapid adjustment of tension method, the machine boot process at the same time to set the pace, the acceleration process, deviation from the PID autocorrection tension. The machines actually running results show that, the tension can be achieved quickly and smoothly control, start acceleration time is short, without a lot of debugging can be quickly put into use, fast running speed to achieve highspeed drawing requirements.
