Wire Drawing Machine

Product Description

Wire Drawing Machines to draw low carbon steel wire from big diameter 6.5mm to smaller diameter such as 3mm, 1.8mm etc for nail making factory, binding wire making factory etc.

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.

Wire Drawing Powder

Wire drawing powder is a kind of lubrication powder, widely used in metal wire drawing process, such as low carbon steel wire, low carbon steel wire(Q195/SEA1008/Q235/SEA1006,etc), stainless steel wire, Welding rod, cold heading wire, etc. The quality of the wire drawing powder is vital important for wire drawing machine, it is mainly made from lime, water, soap, animal fat, paraffin, octadecanoic acid, talcum powder aund borate etc.

How to make the wire drawing powder or if you want to get the recipe, pls contact us for more infomation.

During drawing process, the better oiliness of the drawing powder, the better quality, for nail making, the better quality the better lubrication performance, after drawing, the wire color will looks black and shine and duringnail making,the wire will be eash to cut and this can also make nail cutter long lifetime for example 1 month.

If the lubrication is not good,the drawn wire will looks white and it will cost nail cutter break very soon, maybe 1 or 2 days the cutter will break.

Features of Wire Drawing Lubricant:

  • Dry wire drawing lubricants firmly absorb on wire surface, when the wire pass through the wire drawing dies, which can effectively segregate the two interfaces of the deformed areas.
  • Lubrication powder is not only can stick on wire surface but also can extend with wire deformation.
  • Resist high press and high temperature: Under the condition of high press and high temperature in wire drawing process, the wire drawing lubrication powder also keep continuity and lubrication to avoid breaking, coking metamorphic and agglomerate.
  • The basis elements which consist of the drawing powder don’t react with the steel and will not corrode the steel wire, and also the powder is easy to remove.
  • Wire drawing powder is safe, no pollution for the environment, harmful to human body, low cost and easy to store.

Wire Drawing Dies

Wire drawing dies is used in wire drawing machines, there are different size of the wire drawing dies, for example 5.8mm, 5.0mm,4.5mm, 3.0mm etc, you can get different wire diameter by using the right size of the wire drawing dies.

Size need according to the drawing consition.

Drawing dies are typically made of tool steel, tungsten carbide, or diamond, with tungsten carbide and manufactured diamond being the most common. For drawing very fine wire a single crystal diamond die is used.For hot drawing, cast-steel dies are used. For steel wire drawing, a tungsten carbide die is used. The dies are placed in a steel casing, which backs the die and allow for easy die changes. Die angles usually range from 6–15°, and each die has at least 2 different angles: the entering angle and approach angle.

The set of the machines is an ideal equipment for drawing wire stock of high, medium and carbon steel, as well as coper, alumium and alloy. The machine are applied for drawing wire in the factories, such as wire-steel factor, metal mesh factory and nail making factory etc.

In order to lower residual heat on the surface of the block, the cooling means is installed in inter-wall of the block, the wortle is soaked in cooling water to reduce its working temperature.

Featured with continue drawing, dry drawing, electrical control, safe to operate and long time use life.

Structure:The equipment consist of main reduction box,die box,wheel frame,wire brace and electric control system,The sponning drawing blocks are driven by motor,with gear coupling runs changeful gears to reduce speed.The drawing blocks are verticaly fixed in sealed box body.The gear pair are lubricated with oil.In order to lower residual heat on the surface of the block,the water cooler is install inwall of the block.The machine runs with coral or linkage.The safety halt gear is installed by the position of operating block.

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. The process of wire drawing changes material properties due to cold working.

The area reduction in small wires is generally 15–25% and in larger wires is 20–45%. The exact die sequence for a particular job is a function of area reduction, input wire size and output wire size. As the area reduction changes, so does the die sequence.

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.
