Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a copper wire drawing machine for the production of flexible cables for communication power supplies. Background Art

[0002] In the process of cable manufacturing, wire drawing of copper wire is the source process of wire production. Usually, a die is used to draw the copper wire to the required diameter. During the wire drawing process of the copper wire drawing die and the copper wire, a large amount of heat will be generated due to the extrusion of the wire. In order to eliminate the stress of the wire after wire drawing, the copper wire needs to be annealed after wire drawing, and a large amount of heat will also be generated during the annealing process. Since copper is a good conductor of heat, the heat will quickly conduct through the copper wire path to the copper wire before wire drawing. When manufacturing general power supply cables, since the cables are relatively thick, the heat can be dispersed, and the power supply cables have low requirements for the bending radius. The conduction of this heat to the previous process will not cause any impact. However, when the cable is used in the communication field, it is required that the cable has a small bending radius, which requires that the previous conduction, wire drawing, annealing and cooling processes maintain their respective temperature regions without interfering with each other, so that the internal phase change of the wire can be controlled by each process.
