Cold drawing of bars
Drawing is a
metalworking process which uses
tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire, bar, and tube drawing the starting stock is drawn through a
die to reduce its diameter and increase its length. Drawing is usually done at room temperature, thus classified a
cold working process, however it may be performed at elevated temperatures to
hot work large wires, rods or hollow sections in order to reduce forces
The basic drawing process for a wire, bar or tube.
