The production process of the water tank type wire drawing machine, it is mainly composed of multiple drawing heads to effectively form its small continuous production equipment deployment. To a certain extent, it draws step by step and places the drawing head in the water tank. , and finally, pull the wire to the required specifications.
Judging from several major domestic water tank wire drawing machine manufacturers, the general equipment is equipped with about 20 drawing heads.
The water tank type wire drawing machine will effectively pass each stage of drawing to a certain extent so that the wire diameter of the steel wire changes. During the entire drawing process, 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 operation of the water tank wire drawing machine is mainly based on the working speed of each drawing head based on the above formula to ensure that each drawing head operates synchronously during operation.
Since the drawing process of the water tank type wire drawing machine is completely completed by mechanical shaft drawing, and these machine shafts are driven under the same main shaft, the entire drawing system depends on the speed difference of the drawing wheel and the online tension. Control sync and harmonize things.
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 control methods:
1) Use tension roller adjustment, and the tension during winding is guaranteed by the counterweight of the tension roller itself.
2) 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.
3) 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.
Installation requirements for water tank type wire drawing machines
- The installation foundation of the wire drawing machine must be very stable to avoid vibration;
- During installation, debugging should be done to make the tensile axis of the wire symmetrical to the center line of the die hole, so that the stress on the wire and the wire drawing die acts evenly.
