Common faults of copper wire drawing machine and solutions

The quality of copper single wire production is an issue of great concern to all cable manufacturers, because the quality and efficiency of wire drawing directly affect the production process of the subsequent process, and also play a decisive role in the quality of the wire. In the production of copper wire drawing machine, it is particularly important to accurately control the outer diameter deviation of the product. Due to the continuous production of copper wire drawing machine, the wire drawing speed will gradually be out of sync with the annealing. During wire drawing, because the traction speed is fast and slow, the wire diameter appears discontinuous and irregular phenomenon of large and small segments. The reasons for this phenomenon during wire drawing are as follows:

1. The tension of the accumulator pulley is unstable. There may be more places where air pressure is used in the production workshop, which may cause the air pressure of the air pump of the wire drawing machine to be higher or lower sometimes, which may cause the deviation of the outer diameter of the monofilament to be unable to be accurately controlled.

2. Annealing wheel copper wire jitters. The copper wire jitter causes it to be annealed when it is loose and tight. The current density of annealing is sometimes larger, sometimes smaller, while the strength of copper wire is relatively low at a higher speed. Therefore, it is easy to ignite the copper wire on the annealing wheel, and the surface of the copper wire is uneven due to the effect of sparks.

3. The wear caused by long-term use of the main motor gearbox makes the speed of the fixed speed wheel of wire drawing not match with the traction speed and take-up speed, thus forming a single wire drawing.

For the above problems, there are the following solutions: provide good lubrication for the accumulator to prevent it from causing reverse friction on the wire during high-speed operation, thus making the wire thinner; Adjust the tension of the wire so that the drawing stroke of the wire is always close to the annealing wheel; Ensure the integrity of the annealing wheel rim and avoid unstable annealing current caused by surface defects of the rim. According to the actual situation of the wire drawing machine, the wire drawing machine is matched again, so that the matching die can meet the requirements.
