Wire drawing

The wire drawing process has changed very little over the years. Uses a combination of a die and/or a series of dies to draw the wire to the selected gauge. Wire drawing has many applications beyond what we normally imagine, such as electrical wires and television cables.

For example, springs of any kind are made of drawn wire;

As well as rebar used for construction around the world. Clips and clamps are made of thin drawn wire. Wheel spokes, wire brushes, and metal handles are also made from drawn wire. There literally thousands of finished products that rely on drawn thread. To meet this growing demand, metal processing companies draw many millions of kilometers of wire each year. For this reason, wire drawing, although the process has not changed for many years, is a very sensitive and competitive market. Panel pin making machine

companies that manufacture wire drawing

On the other hand, companies that manufacture wire drawing equipment and wire drawing process equipment are very much in tune with any productivity or efficiency advantage they gain. One of the main advantages is the use of an AC inverter. Inverters are more efficient, use fewer parts and allow higher productivity than traditional designs. The common diagram below illustrates the wire drawing process.

If multiple dies are used, they connect in series until the desired cross-section reached. It is very important to maintain the tension and speed of the wire as it passes through the machine. This creates a constant cross-section. Wire drawing The science behind wire drawing Metallurgy is the study of metals and metal processes. When handling metal, there is a defined rate of change in metal characteristics based on stress and strength at different temperatures.

Wire drawing

Wire drawing is a metalworking process used to reduce the cross-section of wire by drawing it through a series of dies. This process is a form of forging. Forging is a plastic or permanent modification of a metal shape. Forging can be done at warm, hot or cold temperatures. Because metals have different properties at different temperatures; it is possible to change the characteristics of the metal itself as the temperature rises. When the wire is removed, it remove at room temperature.

Cold working

At this point it is done “cold”. Cold working of a metal is a term used for plastic deformation at room temperature without changing the properties of the metal.

When the wire is drawn, the metal does not change its properties, it only changes its shape. Wire drawing process The process itself is actually quite simple. To begin the threading process, a spool of thread is placed at the beginning of the spool machine. In order for the wire to pass through the machine, the end of the wire must cut. Or flattened. It is done with a machine. And a series of dies to achieve the final cross-sectional area.

barrel packer

The end of the machine usually has a coil or winder, so that the final product is a coil of wire of the desired cross-sectional area. The final process can also be a barrel packer, where the barrel is placed and the coiled wire is inserted directly into the barrel using a turntable. It is very important that the temperature of the machines is not too high. And that the wire has a constant tension and speed as it moves through successive dies.

DC drive

Historically, this has only been achieved by mechanical means. However, DC drives are beginning to be used to some extent to power motors depending on the metal. And cross section require. As technology advances, software added for winding applications that keep the material at the correct speed and tension to ensure a good product.

Transfers it to electronic technology

It takes some of the mechanics and transfers it to electronic technology. Electronic linear shaft. Vector control and serial communication are used in many of these modern machines. Definition of electronic linear shaft software Electronic shaft guidance software allows one or more driven motors to be synchronized with the master encoder signal. The master encoder provides a pulse reference to the pulley, which causes the pulley to command its motor to maintain a certain position on the shaft. The slave drive controls pulse feedback from the master encoder and its own encoder.

position errors

The wave then compensates for any position errors by adjusting the output speed of the motor, resulting in near perfect alignment between the main system and the trailed axis motor. There is no accumulation of positional errors, so alignment can always maintaine.

In a wired outlet. One master station used and the others are followers. The software definition further states:

Furthermore, the tracker has an electronic shift function. It will allow the follower to move in master ratio when the two are mechanically connected by belts or gears. This software includes “enhanced” Modbus communication. The registration control function allows the tracker drive to acquire the registration mark of the moving product and control its angular position.

Software is ideal for a wire socket because its winding

like properties require the wire to move at a known and constant tension. And speed. It must always adjust for errors and tracking. The introduction of AC drives not only provides excellent performance but also gives the user the advantage of not relying on mechanical parts that are subject to wear and tear. Preventive maintenance and routine disassembly therefore greatly limited.

Electronic linear

After the wire is stretched. There requirements to cut the length. An electronic linear shaft VFD performs this function very well. There is a closed-loop main drive and a cutting wheel downstream drive. The prime mover must maintain the correct voltage and speed in conjunction with the downstream drive. Barrel packers A wire barrel is an assembly that can placed directly from the wire drawer. Or the coiled wire can take to another station. In the keg packing function. The keg placed on a rotating rotary table. The wire continuously feed into the barrel and rewound.

Barrel rammer

There are usually two motors in a barrel rammer. One for laying the wire and one for turning the turntable. If this process is very slow and independent of voltage but moderate for speed. Use a small open-loop drive combine with a closed-loop vector drive for the turntable. A gramophone version of this song is also available.

replacement disk

In this case, only one replacement disk is installed. Winders and winders Spoilers often found at the end of wire drawing machines. Winders are various machines that wind wires and end products in various thicknesses and strengths. Their sole purpose is to aerate or flush the final product before shipping. Reels can used to guide very large cables at high speeds and up to 1000 hp. The spoilers seem to be smaller. And no more than 50 hp. Although they perform the same function. Winders look smaller than winders and referred to as such in the industry.
