Auto cold drawing machine is a turnkey equipment that specializes in cold working metal tubes and bars. It is available in various shapes and sizes. It streamlines the drawing process by using a hydraulically powered extrusion unit (also known as the push pointer) to clamp the workpiece and then pushing it directly against the draw die. Brass, mild steel and alloy bars are the most common materials to be drawn on this type of machine. Once the drawing is complete, the drawn material is carried by discharging arms to designated collection racks next to the draw bench.
Cold drawing is a deformation process that can significantly affect the mechanical properties of the wire. The tensile strength and yield strength of the wire can increase or decrease depending on the amount of cold drawing it undergoes. This is because the cold drawing process can produce work hardening, which changes the metal’s strength. The exact changes in tensile and yield strength from cold drawing are specific to the particular alloy under study, so they must be calculated using mathematical models of the drawing process.
During the drawing process, the die squeezes and deforms the metal to change its cross section. This can change the shape of the rod, for example, from a round to square bar. For this reason, it is important to make sure that the size of the rod before and after cold drawing is the same. If the diameter is too large, it will be difficult to draw.
The energy-power parameters of the drawing process depend on technological factors, such as the mechanical characteristics of the metal, its tendency to harden during cold deformation, a single degree of deformation, the friction coefficient at the metal-wire contact area, and the quality of the surface preparation of the die and wire rod. The accuracy of these factors will determine the adequacy of the calculated values of the energy-power parameters of the drawing process.
