The wire drawing machine tower wheel is mainly used for wire transmission. After the metal wire is stretched by the wire drawing die, it is wound on the tower wheel. The rotation of the tower wheel makes the metal wire transfer to the next drawing die. After being drawn by the wire drawing die, it is then transmitted through the tower wheel. to the next drawing die.
The wire drawing link is the most important working link of the wire drawing machine.
With different metal materials, different silk varieties, and requirements, the wire drawing process is very different, and the requirements for the tower pulley are also different.
The tower wheel requires a certain wear resistance. After a long time of use, the surface of the tower wheel will have dents caused by the friction of the metal wire, which will affect the quality of the metal wire. High wear-resistant tower wheel.
But its price is more expensive, and the extension of life is not directly proportional to the cost input. The working condition of the tower pulley determines that its surface needs to have a high degree of smoothness and wear resistance.
From the perspective of the product terminal, the tower pulley of the wire drawing machine can be divided into a large drawing machine, medium drawing machine, small drawing machine, and micro drawing machine; from the internal control mode and mechanical structure of the wire drawing machine, it can be divided into water tank type and pulley type. There are several main types such as type and straight type.
For products with different requirements, different precision rules, and different metal materials, different specifications of wire drawing machines can be selected.
For wire and cable production enterprises, fine-drawing machines controlled by double-frequency conversion are widely used. Relatively speaking, the required control performance is also low. For most steel wire production enterprises, according to the material characteristics, the accuracy requirements and drawing stability are igh, so more straight wire drawing machines are used.
Although the drawing process is different, its working process is basically the same.
- Pay-off: For the wire-drawing machine, its control does not require too high precision requirements. For most wire-drawing machines, the wire-releasing operation is realized by driving the pay-off frame with a frequency converter, but there are also Some wire-drawing machines controlled by double frequency conversion are even directly drawn into the wire-drawing machine through the tension of the wire-drawing link, so as to realize free pay-off.
- Wire drawing: The wire drawing link is the most important working link of the wire drawing machine. Different metal materials, different silk varieties and requirements, the wire drawing process is very different. The specific operation process of the water tank type wire drawing machine and the straight wire drawing machine will be explained in detail later in the article.
- Take-up: The working speed of the take-up link determines the production efficiency of the whole wire drawing machine, and it is also the most difficult part of the whole system to control. In the winding part, commonly used control technologies include synchronous control and tension control to realize the winding of metal products.
