Wire stretching is done in order to reduce its cross-sectional area by passing the wire through one or more dosas and stretching it. There are many applications for this type of drawn wire, including springs, cables, musical instruments, automobile manufacturing, etc. This process is usually done at ambient temperature, so it is classified as a cold work operation and improves the properties of the material due to the cold work done on it.

Wire drawing process

This process is conceptually very simple, the wire (wire) is passed through the dosa and is pulled. As the wire is drawn, its volume remains constant, so the diameter decreases and thus the length increases. Consecutive doses are usually used to reach the desired final diameter. In general, the reduction of cross-sectional area is 15-25% in small wires and 20-45% in larger wires.

The size of successive doses used in a drawing process is a function of reducing cross-sectional area, initial diameter and final diameter. The use of lubricants in the stretching process is necessary to increase the quality of the wire surface and the life of the doze, it should be noted that the quality of the lubricants has a significant effect on the final quality of the tension.

One of the most common methods is stretching. in which the wires are completely immersed in the lubricant, another method is dry (cold) stretching, where the wires pass through a container containing a lubricant (usually stretching powder) and cover it.
