Wire drawing system for irregular wires

Abstract

The invention discloses a wire drawing system for irregular wires. The wire drawing system comprises a multi-die sliding type wire drawing machine, at least one non-sliding type wire drawing device and an electrical control device, wherein the non-sliding type wire drawing device is arranged behind the station of the multi-die sliding type wire drawing machine and comprises a wire branching wheel, a wire drawing die, a wire drawing drum wheel, a driving motor and the electrical control device; the wire drawing drum wheel is positioned at the wire outlet of the wire drawing die; the driving motor is connected with the wire drawing drum wheel; the wire branching wheel is arranged at the same level as the wire drawing drum wheel; the wire branching wheel is provided with a plurality of wire branching channels; wires are wound in the wire branching channels; and by the transmission of the wires, the wire branching wheel rotates along with the wire drawing drum wheel. The wire drawing system can meet the needs of the wires for different compression ratios so as to realize multi-stage synchronous-drawing on the irregular wires; and the wire drawing system is beneficial for improving the surface quality of the irregular wires as well as necessary drawing technological requirements.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a wire drawing system for drawing special-shaped wires. Background technique [0002] At present, the overhead transmission lines of ordinary power overhead transmission lines are generally formed by twisting multiple strands of aluminum wires, and the cross-section of the aluminum wires is circular. When these round aluminum wires are twisted together, there will be gaps inside the formed twisted wire, and the structure is not tight enough; the surface of the twisted wire is not smooth enough, so that the service life of the overhead transmission line under wind load and ice load is limited. Larger impact, even in the weather of ice and snow and freezing rain, a large amount of ice and snow accumulate on the overhead cable, and the accumulation is bigger and bigger, and even the overhead cable is broken, the iron tower is crushed, causing transmission accidents and huge econom...

Problems solved by technology

[0004] However, in the drawing process of special-shaped wires, since the drawn special-shaped wires are not allowed to slide on the drawing drum, the surface of the wires will not be scratched and the quality of the cables will be affected. Therefore, the existing traditional sliding wire drawing machine is adopted. The drawing process of special-shaped wire cannot be satisfied, and the drawing process equipment of the present invention must be adopted

But there is no drawing equipment specially used for drawing special-shaped wire rods
