wire rope drawing factory

Incoming raw material (wire rod) is prepared for processing through a series of cleaning and/or surface treatment techniques, which include etching, pickling, and coating.

Wire mill rod coils with larger diameters are initially drawn down to sizes suitable for additional processing on equipment with small diameter output. Allows for multiple finished sizes to be drawn from an initial “redraw” size which in practice shortens lead times.

When the wire is drawn, it builds up strength due to work hardening. Time at temperature “softens” the wire and allows for continued processing or increased ductility or varied electrical properties in specific applications.

Particular wire alloys can be strengthened by “soaking” in a low-temperature bath. Also useful in strand and cable products where mechanical processes do not straighten effectively.

Processing wire in a dry lubricant to reach a desired diameter and tensile strength. Most common in larger diameters (above .040”) where surface area reductions are low and heat dissipation is not a primary concern. Creates a matte appearance of the surface finish which can be desirable for some aesthetic applications.

Processing wire in a liquid lubricant can be water or petroleum-based. Most common in smaller diameters where heat and penetration of the dies becomes a concern. Produces a shiny, smooth surface finish that is desirable in many applications — used primarily in finished diameters below .040”.

High-speed drawing of wire for critical applications with diameters in the 0.005” to 0.010” range requires specialized dies and drawing fluids to maximize strength and surface finish.

Aqueous acid wash or hot alkaline baths remove wire drawing lubricants to offer a cleaner material that extends furnace and lubricant life in downstream processing. Finished products are shipped that eliminate the need for additional cleaning before installation or further processing.

Processing bulk wire spools onto packages suitable for shipment. Labeling, marking, and kitting of the finished product. Customizable to any specification.

Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing die(s). There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments. Although similar in process, drawing is different from extrusion, because in drawing the wire is pulled, rather than pushed, through the die. Drawing is usually performed at room temperature, thus classified as a cold working process, but it may be performed at elevated temperatures for large wires to reduce forces.

The wire drawing process is quite simple in concept. The wire is prepared by shrinking the beginning of it, by hammering, filing, rolling or swaging, so that it will fit through the die; the wire is then pulled through the die. As the wire is pulled through the die, its volume remains the same, so as the diameter decreases, the length increases. Usually the wire will require more than one draw, through successively smaller dies, to reach the desired size. The American wire gauge scale is based on this. This can be done on a small scale with a draw plate, or on a large commercial scale using automated machinery.

Very fine wires are usually drawn in bundles. In a bundle, the wires are separated by a metal with similar properties, but with lower chemical resistance so that it can be removed after drawing.annealing before it can be redrawn.

Commercial wire drawing usually starts with a coil of hot rolled 9 mm (0.35 in) diameter wire. The surface is first treated to remove scales. It is then fed into a wire drawing machine which may have one or more blocks in series.

Single block wire drawing machines include means for holding the dies accurately in position and for drawing the wire steadily through the holes. The usual design consists of a cast-iron bench or table having a bracket standing up to hold the die, and a vertical drum which rotates and by coiling the wire around its surface pulls it through the die, the coil of wire being stored upon another drum or "swift" which lies behind the die and reels off the wire as fast as required. The wire drum or "block" is provided with means for rapidly coupling or uncoupling it to its vertical shaft, so that the motion of the wire may be stopped or started instantly. The block is also tapered, so that the coil of wire may be easily slipped off upwards when finished. Before the wire can be attached to the block, a sufficient length of it must be pulled through the die; this is effected by a pair of gripping pincers on the end of a chain which is wound around a revolving drum, so drawing the wire until enough can be coiled two or three times on the block, where the end is secured by a small screw clamp or vice. When the wire is on the block, it is set in motion and the wire is drawn steadily through the die; it is very important that the block rotates evenly and that it runs true and pulls the wire at a constant velocity, otherwise "snatching" occurs which will weaken or even break the wire. The speeds at which wire is drawn vary greatly, according to the material and the amount of reduction.

Machines with continuous blocks differ from single block machines by having a series of dies through which the wire is drawn in a continuous fashion. Due to the elongation and slips, the speed of the wire changes after each successive redraw. This increased speed is accommodated by having a different rotation speed for each block. One of these machines may contain 3 to 12 dies.

Often intermediate anneals are required to counter the effects of cold working, and to allow further drawing. A final anneal may also be used on the finished product to maximize ductility and electrical conductivity.

While round cross-sections dominate most drawing processes, non-circular cross-sections are drawn. They are usually drawn when the cross-section is small and quantities are too low to justify rolling. In these processes, a block or Turk"s-head machine are used.

Lubrication in the drawing process is essential for maintaining good surface finish and long die life. The following are different methods of lubrication:

Roller die Drawing (also referred as Roll drawing): roller dies are used instead of fixed dies to convert shear friction to rolling friction with dramatic reduction in the drawing forces as reported by Lambiase.

Various lubricants, such as oil, are employed. Another lubrication method is to immerse the wire in a copper(II) sulfate solution, such that a film of copper is deposited which forms a kind of lubricant. In some classes of wire the copper is left after the final drawing to serve as a preventive of rust or to allow easy soldering.

The strength-enhancing effect of wire drawing can be substantial. The highest strengths available on any steel have been recorded on small-diameter cold-drawn austenitic stainless wire.
