Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figures 1 to 4 As shown, the utility model provides a nylon wheel wire drawing device, comprising: a wire drawing machine body 1, a wire drawing pair wheel 22 and a nylon polishing wheel 5, wherein the wire drawing pair wheel 22 and the nylon polishing wheel 5 are respectively axially connected to the front side surface of the wire drawing machine body 1.

[0020] The outer cover of the wire drawing wheel pair 22 is connected to the wire drawing processing cover 2, and the wire drawing processing cover 2 is fixed to the front surface of the wire drawing machine body 1 by bolts. An air guide plate 21 is welded inside the upper end of the wire drawing processing cover 2, and an air supply mesh port 25 is opened at the concave surface of the lower end of the air guide plate 21. The air supply mesh port 25 is distributed on the outer side surface of the upper end of each group of wire drawing wheel pairs 22. The upper end of the wire drawing processing cover 2 is connected to a cold fan 3 through a cold air duct 31, and the inner side of the air guide plate 21 is connected to the cold air duct 31 through an air guide cavity 24. The lower end of the wire drawing processing cover 2 is connected to a waste chip bag 4 through a discharge port 27.

[0021] When the copper material is subjected to wire drawing, the copper material is introduced into the middle of the wire drawing wheels 22 in the wire drawing processing cover 2 through the feed roller 11. At this time, the wire drawing wheels 22 and the copper material are subjected to friction drawing. At the same time, the cold fan 3 is started to blow cold air to the surface of the wire drawing wheels 22 through the air supply mesh port 25, so as to reduce the heat generated by the friction of the wire drawing wheels 22. After wire drawing friction of multiple groups of wire drawing wheels 22, the copper material passes through the wire drawing die 23 and is then wound around the roller surface of the guide roller 12, so that the guide roller 12 transports the wire drawn copper material to the nylon polishing wheel 5. After being polished by the nylon polishing wheel 5, the wire drawing process is completed.

[0022] In this embodiment, the front end surface of the wire drawing machine body 1 is connected to a feed roller 11 and a guide roller 12 through a motor shaft, the feed roller 11 is distributed on the left side of the wire drawing processing cover 2, and a protective frame 51 is fixed to the outside of the nylon polishing wheel 5.

[0023] As a preferred embodiment, the feed roller 11 is used to transport the copper material into the wire drawing processing cover 2, and the guide roller 12 is used to transport the copper wire wound on the roller surface to the nylon polishing wheel 5.

[0024] In this embodiment, the guide roller 12 is distributed between the wire drawing cover 2 and the protection frame 51. The wire drawing die 23 is fixed to the right port of the wire drawing cover 2. The front frame cover 52 is hingedly connected to the front surface of the protection frame 51. An exhaust fan 54 is embedded and installed on the upper end surface of the protection frame 51; and the exhaust fan 54 is located above the nylon polishing wheel 5. A waste box 53 is plugged into the lower end surface of the protection frame 51, and a ventilation mesh port 55 is opened on the side of the waste box 53.

[0025] As a preferred embodiment, the wire drawing die 23 controls the size and shape of the copper material so that the copper material meets the wire drawing processing standard after the wire drawing passes through the wire drawing die 23. The exhaust fan 54 draws external air into the protective frame 51, so that the waste chips generated by the nylon polishing wheel 5 in the protective frame 51 are blown into the waste chip box 53 for collection.

[0026] In this embodiment, the surface of the discharge port 27 is tightened with the bag opening of the waste bag 4 through a fixing ring 41, and a cooling fan 3 is installed on the upper end surface of the wire drawing machine body 1, and a cooling air duct 31 is connected to the right side of the cooling fan 3.

The cooling fan 3 supplies air to the wire drawing hood 2 through the cold air duct 31, and uses air cooling to cool down, while facilitating the blowing of waste into the waste bag 4. The brush plate 26 contacts the copper material entering and exiting the wire drawing hood 2, sweeping away impurities or waste on the surface of the copper material. The air supply mesh port 25 blows cold air to the upper drawing wheel side end face and the upper wheel surface of the lower drawing wheel of the wire drawing wheel pair 22, thereby reducing the heat of the wire drawing wheel pair 22.

[0028] In this embodiment, the wire drawing cover 2 , the air guide plate 21 , the air guide cavity 24 , the air supply mesh port 25 , the cooling fan 3 and the cooling air duct 31 constitute an air cooling mechanism of the wire drawing machine body 1 .

[0029] As a preferred embodiment, the air-cooling mechanism of the wire drawing machine body 1 is convenient for reducing the temperature generated by the friction between the wire drawing wheels and the copper material, avoiding high-temperature oxidation of the copper material caused by the heat of continuous wire drawing, and ensuring the wire drawing effect of the nylon wheel wire drawing device during continuous processing.

[0030] The nylon wheel wire drawing device of the utility model can effectively solve the problem in the prior art that the friction between the grinding roller and the grinding roller for long wire drawing causes the temperature of the friction surface to continue to rise, affecting the wire drawing effect. It is convenient to reduce the temperature generated by the friction between the wire drawing wheel and the copper material, and avoid the high-temperature oxidation of the copper material caused by the heat of continuous wire drawing.
