Application Overview: Wire Drawing

The wire drawing process has remained virtually unchanged for many years. It uses a die and/or a combination of dies to draw the wire to a selected gauge. Drawn wire is used in many applications beyond what we normally think of as wire and TV cable. For example, springs of any kind are made from drawn wire; and steel rebar used in construction around the world. Paper clips and staples are made of fine drawn wire. Wheel spokes, wire brushes, and metal handles are also made of drawn wire. There are thousands of finished products that depend on drawn wire. Next, the wire drawing machine manufacturer will share the following content with you.

To meet this growing demand, metalworking companies pull millions of miles of wire each year. For this reason, wire drawing, although unchanged for many years, is an extremely cost-sensitive and competitive market.

In turn, companies that manufacture wire drawing equipment and the process equipment that surrounds it are very attuned to any productivity or efficiency advantages they can gain. One of these major advantages is the use of AC inverters. Inverters are more efficient, use fewer parts and are more productive than conventional designs.

Wire drawing process

The process itself is actually quite simple. In order to start the wire drawing process, a spool of wire is placed on the spool at the beginning of the wire drawing machine. In order to feed it into the machine, the end of the thread must be cut or flattened. It is fed through the machine and a series of dies to reach its final cross-sectional area.

The wire drawing machine usually has a spool or winder at the end, so the finished product is a coil with the desired cross-sectional area. The final process may also be a barrel sealer, where a barrel is placed and a turntable is used to wind the coiled wire directly into the barrel.

It is critical that the temperature of the wire drawing machine does not become too hot (caused primarily by the energy released as the metal deforms) and that the wire has constant tension and speed as it passes through a series of dies. Historically, this has been achieved entirely by mechanical means. However, depending on the metal and cross section required, DC drives began to be used to run motors at specific levels.

As technology improved, software was added for winder applications to move the material at the proper speed and tension to ensure a good product was produced. This eliminated some of the mechanisms and transferred them to electronics. With the introduction of high performance/high efficiency AC drives and powerful software processors, the mechanical dependence on the wire drawing machine was greatly reduced.

Drives and drawing processes

As mentioned above, AC inverters can be used for a variety of functions on wire drawing machines, as they are very similar to wire winders. Electronic spooling, vector control and serial communication are used on many modern machines.
