Description

Technical Field

[0001] The utility model relates to the technical field of cable copper wire drawing, in particular to a cable copper conductor wire drawing antioxidant coating die. Background Art

[0002] In the process of drawing copper wire of cable, drawing oil needs to be added to play a lubricating role. Usually, during the transmission process of copper wire, the copper wire is first immersed in the oil tank filled with drawing liquid, and then passed through the drawing die for drawing operation. Since the copper wire will produce stress changes after drawing, causing the surface to be easily oxidized and discolored, antioxidants are usually added to the drawing oil to prevent the surface of the copper wire from oxidizing after drawing. However, during the process of drawing copper wire, most of the drawing oil falls off the surface, resulting in poor antioxidant effect. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a cable copper conductor wire drawing antioxidant coating die, in which antioxidant is added to the wire drawing die to prevent the surface oxidation of the copper wire after drawing.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cable copper wire drawing antioxidant coating mold, including a vertically arranged mold body, the lower end of the mold body is a large opening, the upper end is a small opening, the upper end of the mold body is connected to an infiltration tube, the upper end of the infiltration tube is open, and the lower end is connected to the mold body; a liquid inlet pipe is connected to the side wall of the infiltration tube, and antioxidant liquid is poured into the infiltration tube from the liquid inlet pipe.

[0005] Preferably, a threaded connection pipe is provided at the lower end of the infiltration tube, and the threaded connection pipe is threadedly connected to the upper end of the mold body.

[0006] Preferably, a mounting plate is provided on the outer side of the infiltration tube.

[0007] Preferably, a mounting hole is provided on the mounting plate.

[0008] The utility model provides a cable copper conductor wire drawing antioxidant coating die, which can coat the surface of the copper wire with antioxidant liquid when the copper wire drawing is completed, thereby preventing the surface of the copper wire from being oxidized after drawing without adding other equipment.

[0014] like Figure 1-3 As shown, a cable copper conductor wire drawing antioxidant coating mold includes a vertically arranged mold body 1, the lower end of the mold body 1 is a large opening, the upper end is a small opening, the upper end of the mold body 1 is connected to an infiltration tube 2, the upper end of the infiltration tube 2 is open, and the lower end is connected to the mold body 1; a liquid inlet pipe 3 is connected to the side wall of the infiltration tube 2, and an antioxidant liquid is poured into the infiltration tube 2 from the liquid inlet pipe 3.

[0015] Preferably, a threaded connection pipe 4 is provided at the lower end of the infiltration pipe 2, and the threaded connection pipe 4 is threadedly connected to the upper end of the mold body 1. The threaded connection facilitates replacement of molds of different sizes.

[0016] Preferably, a mounting plate 5 is provided on the outer side of the infiltration tube 2 .

[0017] Preferably, the mounting plate 5 is provided with a mounting hole 6. The mounting plate 5 and the mounting hole 6 facilitate fixing the device.

[0018] When using, Figure 4 As shown, the copper wire moves from bottom to top, and is stretched thin when passing through the die body 1. After being stretched thin, it enters the impregnation tube 2, and the antioxidant liquid is introduced into the impregnation tube 2 by the liquid inlet tube 3, thereby completing the operation of coating the surface of the copper wire with the antioxidant liquid. The copper wire moves vertically upward, and the excess antioxidant liquid on the surface flows downward under the action of gravity and then returns to the impregnation tube 2. As the copper wire moves, the antioxidant liquid in the impregnation tube 2 will gradually be consumed, and the impregnation liquid will be continuously replenished through the liquid inlet tube 3. The copper wire after being drawn by this device enters the subsequent process, and this device is used as the last die of multi-stage drawing.

[0019] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
