[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another. Cold drawing is a processing technology for metal materials. It means drawing the material at room temperature in order to achieve a certain shape and certain mechanical properties. The cold-drawn product has the advantages of high dimensional accuracy and good surface finish.

[0003] Chinese patent CN217251616U discloses a cold drawing device for cable production, including an adjustment mechanism for adjusting the thickness of the cold drawn wire core, a winding mechanism for winding the outgoing cable is arranged on one side of the adjustment mechanism, a cutting mechanism for cutting the wound cable is arranged on the winding mechanism, and a guiding mechanism for guiding and laying the wound cable is arranged between the winding mechanism and the adjustment mechanism, and the guiding mechanism is connected to the adjustment mechanism. The utility model adjusts the inner diameter of the extrusion block of the adjustment mechanism so that the passing cable can be drawn in multiple specifications under the rotation of the roller, and at the same time, the drawn cable can be alternately replaced after winding through the setting of the guiding mechanism, the winding mechanism, and the cutting mechanism, and the winding wheel can be replaced without stopping the machine, thereby improving the cable drawing production efficiency, reducing the labor intensity, and better adapting to production needs.
