Application and Usage of Wire Drawing

Wire drawing is a metalworking technique that involves dragging the wire through one or more drawing dies to lower the cross-section of the wire. Wire drawing has numerous uses, including the manufacture of cables, tension-loaded structural elements, paper clips, wheel spokes, and stringed musical instruments. Drawing differs from extrusion while having a similar technique, in that the wire is dragged through the die as opposed to being pushed through it.

Types of Wire Drawings 

  • Hydrostatic wire drawing 
  • Bundle wire drawing 

Hydrostatic Wire Drawing 

It has gained widespread acceptance and is especially well-suited for composites and fragile materials. It is not necessary for the billet to be straight or cylindrical when using hydrostatic extrusion, nor does it have to have a consistent cross-sectional area over its entire length. 

Bundle Wire Drawing 

Wires made through bundle drawing have more polygonal than rounded cross-sections. Techniques have been devised to make FireWire in both continuous lengths and sliced into a variety of diameters and forms.  

Process of Wire Drawing 

  • The beginning of wire-drawing process begins with the coil of wire rod being placed on a spool at the machine’s start. 
  • The end of the wire rod is either chopped or slightly flattened to feed it through the machine to begin the procedure. 
  • When there are sufficient “wraps” of wire around the machine’s drawing blocks for the machine to continue feeding automatically, pulling-in-dogs are utilized to drag the intake wire around those blocks. 
  • To get the appropriate final cross-sectional area, it is then put through a sequence of dies. A coiler that rolls the wire into a coil is located at the machine’s end.
