Wire machinery is basically a metal working process which reduces the cross section of a wire by pulling it through single, series and drawing dies.
Wire machinery and its working mechanisms:
Wire machinery works on the principle of wire drawing processes. The wire is prepared by shrinking the beginning of it and by hammering it. The wire is often pulled through the dye as its volume remains static. The length of the wire increases automatically as its diameter decreases. The machine uses fine wires which are drawn in bundles. These wires are often separated by a metal having similar property with low chemical resistances so that one can remove it by drawing mechanisms. Wire drawing usually starts with a coil hot rolled up to nine millimeter in diameter with the help of the die. These wires are fed into wire drawing machine which might have one or more blocks in series. The usual design consists of a cast iron bench or table having a bracket holding the whole instruments. The wire on the block is drawn with the help of the die. On the other hand wire drawing is completely a different method to that of extrusion method. In this method drawing wire is often pulled rather than being pushed through the dye. The process of drawing is mostly performed at a room temperature thus regards extrusion as a cold working process.
Lubrication an alternate methodology for maintenance of Wire Machinery:
This method allows the wire to maintain a good surface area along with a long die life. The methods involve that of wet drawing in which both the wire and dyes are fully immersed in a lubricant solution. Dry drawing is another mechanism which involves lubrication and coating of the surface of the wire or rods, where as metal coating involve the coating of soft metal which act as a solid lubricant. On the other hand ultrasonic vibration is the method which helps to reduce the force and allow surface reduction of per pass. Last but not the least is a process where one can immerse a wire in a plain copper sulfate solution. The example of copper coated wire includes that of MIG wire or that of CO2 wire which are more often used for the purpose of welding.
Mechanical property of Wire Machinery:
This mechanism involves use of both force and strength to draw a wire at a substantial rate. These wires have higher tensile strength to that of steel materials.
Application of wire machinery:
There are wide range of applications of wire machinery which includes that of electrical wiring, cables, tension loaded structural components, paper clips, stringed musical instrument and that of spokes of wheel.
In conclusion it can be said that wire machinery consists of drawing dies which are often made up of tool steel, and that of tungsten carbide. This equipment uses electrical power to pull the wire thoroughly. Often this machinery has coiled wire on both ends which pulls up the wire within a reduced diameter.
