Problems solved by technology

[0004] However, in the actual use of high-power all-electric bending machines, there is a phenomenon of position asynchrony caused by the unbalanced force of each motor, which leads to strong mechanical coupling, and strong mechanical coupling will cause moving parts such as sliders to twist. Inclined, aggravate the wear of the transmission components such as the screw, reduce the machining accuracy and the life of the machine tool, and damage the driving components and the traveling mechanism in severe cases
