Abstract

The paper proves possibility to increase quality of reinforcing wire by means of enhancement of the unwinding machine electric drive control system at the rebar production line. An analytical equation for the required alteration in the unwinding machine electric drive's breaking torque needed to stabilize wire tension at a specified level between the roller-straightening device and profile stand is offered. Tension variations due to breaking torque alteration in the active control system of the unwinding machine electric drive have been compared; calculation with the proposed equation has proved that the wire fill-in radius of the reel within an active control system is decreased during unwinding process accompanied by a considerable decline in wire tension. On the contrary, if offered equation is used to vary breaking torque of the drive in response to the fill-in radius decrease, wire tension is stabilized. A method for calculation of efficient braking torque alteration of the unwinding machine electric drive at varying wire fill-in radius of the reel has been developed.

钢筋生产线放卷机电动传动断转矩变化的计算方法

通过对钢筋生产线放卷机电气驱动控制系统的改进，证明了提高钢筋质量的可能性。给出了为使卷筒矫直装置与型材架之间的钢丝张力稳定在某一水平所需的放卷机电气驱动断转矩变化的解析方程。比较了电驱动放卷机主动控制系统中断转矩变化引起的张力变化;利用所提出的方程进行的计算证明，主动控制系统下的卷筒放卷过程中，卷筒的填线半径减小，同时卷筒的张力显著下降。相反，如果利用所提供的方程来改变驱动器的断裂力矩，以响应填充半径的减小，则丝张力稳定。提出了一种计算电动放卷机在不同卷线半径下的有效制动转矩变化的方法。
