During the wet wire drawing manufacturing process, the wet wire drawing machine is mainly a small continuous production equipment composed of multiple drawing heads. During operation, it draws step by step and places the drawing heads in the water tank. Finally, the steel wire is Pull to desired specifications.
The general equipment is equipped with about 20 pulling heads. After each stage of drawing, the diameter of the steel wire changes, so the linear speed of each drawing head should also change.
During the entire wet wire drawing manufacturing process of the water tank wire drawing machine, only one motor is required to drive it through a mechanical transmission or gearbox. According to the different drawing die configurations, the drawing speed of each drawing head will also change. The benchmark for the drawing rate is the steady flow volume per second of the steel wire passing through the drawing die at each time.
The working speed of each drawing head of the wet wire drawing machine is based on the above formula. During operation, each drawing head is guaranteed to run synchronously. During operation, the wet wire drawing manufacturing process of the wet wire drawing machine completely passes through the mechanical axis.
Drawing is completed, and these mechanical axes are driven under the same spindle, so the entire stretching system relies on the speed difference of the stretching wheel and the online tension to control synchronous and coordinated work.
The water tank wire drawing machine requires coolant for heat dissipation. The take-up part is driven by a low-power motor. It is necessary to keep the tension on the line constant during winding. If the tension in this section fluctuates, the winding on the I-wheel of the winding will be uneven.
The winding link of the water tank wire drawing machine is the core link in the equipment deployment control system, which also directly affects the quality of the steel wire. For winding, there are usually several wet wire drawing machine control methods:
- Use tension roller adjustment, and the tension during winding is guaranteed by the counterweight of the tension roller itself.
- Using torque control, the tension during winding is determined by the size of the torque given, but the change in winding diameter will lead to unbalanced winding tension.
- For water tank wire drawing machines with high process requirements, a control method is usually adopted, using the PID correction function of the frequency converter ACS510 to control the tension roller adjustment.
