焊丝层绕机的变频张力控制

Frequency Conversion Tension Control of Layer Winder for Welding Wire

介绍焊丝层绕机的工艺要求和目前状况,论述层绕过程中张力的变化规律,给出系统张力控制框图,对PLC模数接口电路进行详细说明,对张力PID控制的参数要求及变化规律进行讨论,指出合适的电机参数和PID参数设置可以确保层绕机工作在20m/s。

To introduce the process requirement and present situation of layer winder for welding wire. The tension change rule in the course of layer winding is discussed, and the tension control block diagrams of system are given. The interface circuit of PLC analog and digital signals is expounded. The parameters requirements and change rule of tension PID control are discussed. It is pointed out that the suitable electromotor parameters and PID parameters setting can ensure layer winder to work at 20 meters per second.
