Description

Technical Field

[0002] Wire drawing machine is a mechanical device used for stretching metal materials. Its main function is to process metal materials such as bars and wires through drawing, cold drawing, processing and other processes to obtain metal wires or strips of different diameters, thicknesses, lengths and surface smoothness. During the processing, the copper wire will go through the processes of unwinding, drawing, annealing, and winding. After the copper wire is drawn, it will reach the annealing process. By heating the copper wire at high temperature and then cooling it quickly, the hardness of the copper wire will be reduced to improve its toughness.

[0003] After the copper wire reaches the annealing process, it will be guided to the annealing wheel in the water tank through the guide wheel. By energizing the annealing wheel, the copper wire will be energized and then raised and lowered for heating, and then the coolant in the water tank will be used to quickly cool the copper wire to achieve the purpose of annealing. The water tank currently used is relatively large, and the copper wire will cause the temperature of the coolant in the water tank to rise during the annealing process.
