Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a temperature-reducing and oxidation-resistant cable drawing machine. Background Art

[0002] During the wire drawing process, the copper conductor will heat up. Excessive temperature will cause oxidation on the copper wire surface. The current solution is to spray or soak the copper wire surface with drawing oil during the wire drawing process. On the one hand, it plays a lubricating role, and on the other hand, it plays a cooling role. However, when the wire is deformed, most of the drawing oil will be scraped off, and after scraping off, it will no longer have a cooling effect. In addition, the copper wire will produce stress changes and temperature rise after wire drawing, causing the surface to be easily oxidized and discolored. Therefore, antioxidants are usually added to the drawing oil to prevent oxidation of the copper wire surface after wire drawing. However, during the copper wire drawing process, most of the drawing oil falls off the surface, resulting in poor antioxidant effect. Summary of the invention

[0020] like Figure 1As shown, a cooling and anti-oxidation cable drawing machine includes a box body 1, in which a plurality of guide wheels 2 are arranged in an up-and-down staggered manner, so that a metal wire 3 moves in a vertical direction after passing through the guide wheels 2; it also includes a plurality of cooling wire drawing dies 4 and an anti-oxidation wire drawing die 5, and the metal wire 3 passes through the plurality of cooling wire drawing dies 4 step by step from top to bottom, and finally passes through the anti-oxidation wire drawing die 5.

[0021] Preferably, Figure 2-4 As shown, the cooling wire drawing die 4 includes a die body 6, the lower end of the die body 6 is a large opening, the upper end is a small opening, the upper end of the die body 6 is connected to a cooling pipe 7, the upper end of the cooling pipe 7 is open, and the lower end is connected to the die body 6; a first liquid inlet pipe 8 and a liquid discharge pipe 9 are connected to the side wall of the cooling pipe 7, and the coolant circulates through the first liquid inlet pipe 8 and the liquid discharge pipe 9 in the cooling pipe 7 to cool the copper wire after drawing.

[0022] Preferably, the lower end of the cooling tube 7 is threadedly connected to the upper end of the mold body 6 , and a mounting plate 10 is provided on the outer side of the cooling tube 7 , and a mounting hole is provided on the mounting plate 10 .

[0023] Preferably, a rubber plug 11 is provided at the upper end of the cooling tube 7, and a through hole for passing the copper wire after drawing is provided in the middle of the rubber plug 11.

[0024] Preferably, Figure 5-7 As shown, the antioxidant wire drawing die 5 includes a die body 6, the lower end of the die body 6 is a large opening, the upper end is a small opening, the upper end of the die body 6 is connected to an infiltration tube 12, the upper end of the infiltration tube 12 is open, and the lower end is connected to the die body 6; a second liquid inlet pipe 13 is connected to the side wall of the infiltration tube 12, and the antioxidant liquid is introduced into the infiltration tube 12 from the second liquid inlet pipe 13.

[0025] Preferably, the lower end of the infiltration tube 12 is threadedly connected to the upper end of the mold body 6, and a mounting plate 10 is provided on the outer side of the infiltration tube 12, and a mounting hole is provided on the mounting plate 10.

[0026] Preferably, the box body 1 is soaked with wire drawing oil 14. The oil level of the wire drawing oil 14 is lower than the height of the plurality of cooling wire drawing dies 4 and the anti-oxidation wire drawing die 5.

[0027] When in use, the metal wire 3 enters the box 1 from left to right, and after being soaked in the wire drawing oil, it passes through multiple cooling wire drawing dies from bottom to top step by step. When passing through the die body, it is thinned, and then enters the soaking tube. The coolant circulates in the cooling tube to cool the copper wire after drawing. At the same time, it can also have the effect of cooling the mold. The plug can prevent the coolant from overflowing and wipe the coolant on the surface of the copper wire to prevent the coolant from overflowing and mixing with the wire drawing oil.

[0028] Finally, the wire passes through the anti-oxidation wire drawing die, and moves from bottom to top. When passing through the die body, it is stretched thin, and then enters the impregnation tube. The second liquid inlet tube introduces the anti-oxidation liquid into the impregnation tube, thereby completing the operation of coating the copper wire surface with the anti-oxidation liquid. The wire moves vertically upward, and the excess anti-oxidation liquid on the surface flows downward under the action of gravity and returns to the impregnation tube. As the wire moves, the anti-oxidation liquid in the impregnation tube will gradually be consumed, and the impregnation liquid will be continuously replenished through the second liquid inlet tube.
