The wire drawing machine tower wheel for metal wire drawing is composed of a number of coaxial and multi-step cylindrical drums with different diameters.
Its main feature is that no matter what material it is made of or what method it uses to harden the surface of the tower wheel.
The tower wheel of the wire drawing machine is composed of a plurality of coaxial cylindrical drums with different diameters. During use, the motor drives the tower wheel to rotate, and the tower wheel drives the steel wire passing through the hole of the drawing die to draw.
Since the surface of each reel of the tower wheel is subjected to uneven friction by the steel wire for a long time, grooves will be formed. When the groove reaches a certain depth, it is very easy to cause “crimping” and break the wire. If you want to continue drawing, you must replace the new cone wheel.
According to the observation of the domestic 9/210, 9/315, 19/200 water tank wire drawing machine and the Italian GCR company TB4 water tank wire drawing machine, the failure mode of the tower wheel is often to produce grooves in the local range of the surface of each drum, while most of the surface remains intact.
From the perspective of the product terminal, 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 High, so more straight wire drawing machines are used.
Although the drawing process is different, the 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 that can even be directly drawn into the wire drawing machine through the wire tension in the wire drawing link, so as to realize free wire unwinding.
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, and the drawing process are very different.
The specific operation process of the water tank type wire drawing machine and the straight type 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;
