Auto Cold Drawing Machine
Auto cold drawing machine is a special type of wire drawing machine that reduces the diameter of metal wire. This process is similar to hot rolling, but it is done at lower temperatures and with less mechanical stress. In addition, it produces less slag and heat than hot rolling. For these reasons, it is used in the production of seamless pipe & tube, coil tube and capillary tubes. In addition, it is also used in other applications where the diameter of the metal needs to be reduced.
The work flow of an automatic cold drawing machine consists of several steps. The first step is the pointing machine, which sharpens the tip of the wire rod and prepares it for the drawing process. This is because the rods are usually conical, and it is easier and more fluid to enter them into the drawing dies if they already have this shape.
After this, the pointing machine is followed by the drawing machine, which takes the rod and gradually reduces its diameter until the desired size is reached. The drawn wire is then fed into a grafiling machine, where the final shape of the wire is given. This machine makes it possible to produce a wide range of wires and alloys, including copper and aluminum.
This cold drawing process is a form of cold deformation, which affects the mechanical properties of the alloy. In particular, it causes the tensile and yield strength to increase while the plasticity decreases. The exact change in the tensile and yield strength depends on the technological parameters of the drawing process, such as the drawing speed, the drawing route and the die angle.
The tensile and yield strengths of the material after the drawing process also depend on the work hardening, which is caused by the cold deformation of the alloy. However, the hardening can be removed by heat treatment.
In addition, the tensile and yield strengths of the materials after the drawing process depend on the shape of the cross section of the alloy. For example, round bars can be shaped into squares by drawing them through different dies. This is a great advantage of cold drawing, as it allows the production of larger and stronger rods than would be possible with other deformation methods such as hot rolling or forging.
