摘要

摘要: 针对金属窄带材卷绕质量要求，设计了一套恒张力控制系统。分析了金属窄带材卷绕生产工艺过程控制中张力产生及其影响因素，在保持恒张力控制的基础上，提出、设计、制作了窄带材卷绕的双闭环、串级、动态控制系统。采用单片机为核心控制单元实现信号采集与控制信号输出，以三相交流力矩电机为主执行机构，结合转速、张力双闭环控制，实现了基于力矩电机的带材卷绕可控恒张力机构；同时以步进电机为辅执行器，以位移检测为反馈量的盘绕机构横移控制；以及以带材厚度为前馈信号的超前控制。通过设计电路图、制作电路板、系统集成应用效果表现出，带材卷绕过程用力均匀，张力稳定，匝间间隙合适，层间松紧适度，盘绕平整、均匀，保证了生产质量。

Abstract: A set of constant tension control system is designed according to the winding quality requirements of narrow-band metal strip. The tension generation and its influencing factors in the process control of metal narrow strip winding production are analyzed. On the basis of maintaining constant tension control, a double closed loop, cascade and dynamic control system for narrow strip winding is proposed, designed and manufactured. The system uses single chip microcomputer as the core control unit to realize signal acquisition and control signal output. With three-phase AC torque motor as the main actuator, combined with double closed-loop control of speed and tension, a controllable constant tension mechanism for strip winding based on torque motor is realized. At the same time, a stepper motor is used as auxiliary actuator and displacement detection is used as feedback to control the coiling mechanism move horizontally. In addition, a kind of feed-forward control mode is designed with the thickness of metal strip as feed-forward signal. After circuit diagrams are designed, circuit boards are made, the system is integrated. The application of the system shows that the winding process of the strip is uniform in force, stable in tension, appropriate in turn-to-turn clearance, moderate in tension between layers, smooth and uniform in winding, which ensures the production quality.
