Description

Technical Field

[0001] The utility model relates to the technical field of cable core wire drawing post-processing, in particular to a cable wire drawing annealing device. Background Art

[0002] When producing copper cable wire, copper rods are first drawn to the desired diameter. During the drawing process, lattice stress in the copper wire gradually increases, affecting both the physical and electrical properties of the wire. Therefore, the copper wire is typically annealed after drawing to eliminate the stress between the lattices and improve its properties.

[0003] However, in the prior art, the cable drawing machine cannot reduce the oxidation rate of the copper wire during annealing. A black oxide layer appears on the surface of the copper wire after annealing, resulting in reduced product quality. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the prior art and provides a cable wire drawing annealing device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A cable wire drawing annealing device comprises a heating annealing chamber, wherein a horizontally arranged annealing cylinder is provided in the heating annealing chamber, an outer cover of the annealing cylinder is provided with an induction heating coil, a first sponge ring is provided on the inner wall of the heating annealing chamber at the cable insertion port, a conductive cotton rope is connected to the top of the first sponge ring, an anti-oxidation liquid storage tank is provided on the outer wall of the heating annealing chamber above the first sponge ring, the anti-oxidation liquid storage tank is filled with anti-oxidation liquid, the conductive cotton rope penetrates into the anti-oxidation liquid storage tank, the drawn cable passes through the first sponge ring and through the center line position of the annealing cylinder in the heating annealing chamber, an inert gas blowing pipe is provided in the heating annealing chamber, and the inert gas blowing pipe extends into the interior of the annealing cylinder.

[0007] The heating annealing chamber is provided with a cooling chamber outside the cable outlet. Cooling circulating water is provided in the cooling chamber. Water inlet and outlet are provided on the side wall of the cooling chamber. Several winding rollers are provided in the cooling chamber. The cables pass through the several winding rollers in turn and are immersed in the cooling circulating water before passing through.

[0008] A drying gas pipeline is provided on the inner wall of the cooling chamber above the cable outlet end, and a plurality of air blowing ports are provided at the bottom of the drying gas pipeline facing the cable.

[0009] A second sponge ring is provided on the inner wall of the cooling chamber at the cable passing-through end, and the cable passes through the second sponge ring.

[0010] The beneficial effect of the utility model is that the utility model can use the first sponge ring to coat the cable surface with an antioxidant liquid before the cable enters the annealing cylinder. In this way, when the cable enters the annealing cylinder for temperature treatment, under the protection of the inert gas, the probability of oxidation is reduced and the quality of the product is improved.
