Used wire drawing machine
With a used wire drawing machine the diameter resp. the cross-section of a
wire is being reduced. To do this the wire is pulled through a drawing die,
which has a through bore slightly smaller than the entering wire. The wire is
driven by the capstans, which are mostly connected by a gear box to the motors.
These capstans surfaces are made from hardened steel or ceramics.
Used wire drawing machines are divided into machine for ferrous (like iron and
steel wire) and non-ferrous (like copper or aluminium) wire. Because iron and
steel being much sturdier than non-ferrous matreials the drawing machines for
this material are often bigger in construction with more power. Also the drawing
speeds are slower with these machines.
Because the meachanical stress applied by this cold reforming process the wire
looses it's flexibility through the drawing process. To compensate this wire are
often annealed after they are drawn to the desired diameter. In non-ferrous wire
drawing this is done with electrical resistance in-line annealers, while iron
and steel wires are mostly put in seperate ovens.
