Technical Field

[0001] The invention relates to the technical field of cable wire drawing machines, in particular to an adjustable wire drawing machine for preparing cables. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the trunk lines of the power system, including 1-500KV and above various voltage levels, various insulated power cables. The cables are made through three processes: drawing, twisting, and coating. Different types of cables have different procedures. The core of wires and cables is usually made of copper. At room temperature, a wire drawing machine is used to pass through one or more drawing die holes to reduce the cross-sectional area of ​​the drawn copper core, increase the length, and improve the strength. This process is the first process in the production of wires and cables and is crucial.

[0003] Different fields and uses have different requirements for the diameter and width of copper wire. If the copper wire drawing device needs to process copper wires of different diameters and widths, it is necessary to replace wire drawing dies of different specifications. The replacement process is relatively cumbersome and labor-intensive, and affects the overall processing efficiency. At the same time, during the adjustment process, if the center of the adjustment hole is not on the central axis of the wire drawing, it will cause uneven force on the metal wire during the stretching process, thereby affecting the wire drawing quality and causing the drawn wire to be uneven in thickness.
