Description

Technical Field

[0001] The invention relates to the technical field of copper rod production, and in particular to a copper rod production device and a production method. Background Art

[0002] Copper rods are raw materials for the production of wires and cables. They are generally produced with electrolytic copper, and their resistivity is lower than that of low-oxygen copper rods. Therefore, oxygen-free copper rods are more economical in the production of products with strict resistance requirements. The manufacture of oxygen-free copper rods requires high-quality raw materials. In the continuous production process of copper rods, after the copper rods are pressed, cleaned and dried, they need to be waxed to prevent oxidation of the copper rods.

[0003] In the prior art, the wax coating of copper rods is generally done manually, which is not only inefficient but also prone to uneven coating, resulting in some parts of the copper rod being coated with more wax, resulting in waste of wax liquid, while other parts are coated with less wax liquid, making it difficult to protect the copper rod. In other wax coating operations, spraying with a nozzle is performed. Although this method improves the spraying efficiency, it still has the problem of uneven spraying, and the wax liquid on the surface of the copper rod will drip and cause waste.

[0030] A production method for a copper rod production device comprises the following steps:

[0031] S1. After the copper rod enters the wax coating chamber from the feed hole, the copper rod passes through multiple wax coating rings in sequence, and the wax coating rings spray the wax liquid onto the outer wall of the copper rod;

[0032] S2. After the copper rod passes through the wax coating cavity, it enters into multiple screed rings. The screed rings rotate to drive the screed plate and the screed sheet to rotate. The screed sheet scrapes the wax liquid on the surface of the copper rod to make the wax liquid evenly distributed on the surface of the copper rod;

[0033] S3. The copper rod passes through multiple material mixing rings and enters the cooling chamber, and finally exits the box through the discharge hole;

[0034] Wherein, in the step S2, the rotation directions of the two adjacent leveling rings are opposite, and the leveling plates and leveling sheets inside the two adjacent leveling rings rotate in opposite directions to scrape the wax liquid on the surface of the copper rod;

[0035] In step S1, a pump delivers the wax liquid in the liquid tank to a plurality of nozzles for spraying;

[0036] In the step S1, when the wax liquid in the liquid tank is at a low liquid level, a fluorescent agent is injected into the liquid tank through a fluorescent agent tube and stirred to mix evenly. The wax liquid evenly mixed with the fluorescent agent is sprayed on the copper rod by a nozzle. In the cooling chamber, ultraviolet light irradiates the surface of the copper rod. The wax liquid on the surface of the copper rod glows due to the fluorescent agent. Multiple cameras observe the luminescence of the copper rod surface from different directions. After all the wax liquid containing the fluorescent agent in the liquid tank is sprayed, new wax liquid is injected into the liquid tank to continue the wax liquid spraying operation.

[0037] When the camera observes the copper rod, if the surface of the copper rod glows evenly everywhere, the production device is working normally and the wax liquid is evenly distributed on the surface of the copper rod. If the surface of the copper rod glows unevenly, with some parts glowing brighter or weaker, the production device is working abnormally and it is necessary to check the abnormal conditions of the wax coating mechanism and the material mixing mechanism and perform repairs.

[0038] The beneficial effects of the present invention are:

[0039] The invention automatically sprays wax liquid on the copper rod when producing the copper rod, thereby improving the wax liquid spraying operation efficiency;

[0040] The nozzles in the wax coating ring are arranged at equal intervals, and the nozzles between adjacent wax coating rings are arranged in a staggered manner, so that the wax liquid sprayed on the surface of the copper rod is evenly distributed;

[0041] Multiple rotating leveling rings drive multiple leveling plates and leveling sheets to scrape the wax liquid on the surface of the copper rod, so that the wax liquid is evenly distributed. Two adjacent leveling rings rotate in opposite directions, so that the leveling plates and leveling sheets with different rotation directions scrape the wax liquid on the surface of the copper rod, further improving the uniformity of the wax liquid on the surface of the copper rod;

[0042] During cooling, the serpentine flow of the airflow increases the contact time between the airflow and the copper rod to increase the heat absorption of the airflow, while reducing the flow rate of the airflow to prevent the wax liquid from evaporating too quickly;

[0043] The box is cylindrical, so that the copper rod in the wax coating cavity is heated evenly, and the air flow in the cooling cavity is evenly distributed to make the copper rod heat evenly, ensuring that the heat exchange at all parts of the copper rod in the box is even;

[0044] When the production device needs to be checked for abnormalities after running for a period of time, fluorescent agent is injected into the liquid tank and mixed evenly with wax liquid. After the wax liquid is sprayed on the copper rod, the luminescence of the fluorescent agent on the copper rod surface is photographed by a camera under ultraviolet light to determine the distribution of the fluorescent agent on the copper rod surface. In this way, the distribution of the wax liquid on the copper rod surface can be determined, and whether the wax coating mechanism and the material leveling mechanism are working normally can be checked.

[0076] In step S1, a pump delivers the wax liquid in the liquid tank 12 to a plurality of nozzles 13 and sprays it out;

[0077] In step S1, when the wax liquid in the liquid tank 12 is at a low liquid level, fluorescent agent is injected into the liquid tank 12 through the fluorescent agent tube, and the stirring component performs a stirring operation to stir and mix the wax liquid and the fluorescent agent. The wax liquid evenly mixed with the fluorescent agent is sprayed on the copper rod by the nozzle 13, and in the cooling chamber 102, ultraviolet light irradiates the surface of the copper rod. The wax liquid on the surface of the copper rod glows due to the fluorescent agent. Multiple cameras 11 observe the luminescence of the surface of the copper rod from different directions. After all the wax liquid containing the fluorescent agent in the liquid tank 12 is sprayed, new wax liquid is injected into the liquid tank 12 to continue the wax liquid spraying operation. If the surface of the copper rod glows evenly, the production device is working normally and the wax liquid is evenly distributed on the surface of the copper rod. If the surface of the copper rod glows unevenly, and there is a situation where the local glow is brighter or weaker, the production device is working abnormally, and it is necessary to check the abnormal conditions of the wax coating mechanism and the material leveling mechanism and perform maintenance.

10. A method for producing a copper rod production device according to any one of claims 1 to 9, characterized in that: The steps include: S1. After the copper rod enters the wax coating chamber from the feed hole, the copper rod passes through multiple wax coating rings in sequence, and the wax coating rings spray the wax liquid onto the outer wall of the copper rod; S2. After the copper rod passes through the wax coating cavity, it enters into multiple screed rings. The screed rings rotate to drive the screed plate and the screed sheet to rotate. The screed sheet scrapes the wax liquid on the surface of the copper rod to make the wax liquid evenly distributed on the surface of the copper rod; S3. The copper rod passes through multiple material mixing rings and enters the cooling chamber, and finally exits the box through the discharge hole; Wherein, in the step S2, the rotation directions of the two adjacent leveling rings are opposite, and the leveling plates and leveling sheets inside the two adjacent leveling rings rotate in opposite directions to scrape the wax liquid on the surface of the copper rod; In step S1, a pump delivers the wax liquid in the liquid tank to a plurality of nozzles for spraying; In the step S1, when the wax liquid in the liquid tank is at a low liquid level, a fluorescent agent is injected into the liquid tank through a fluorescent agent tube and stirred to mix evenly. The wax liquid evenly mixed with the fluorescent agent is sprayed on the copper rod by a nozzle. In the cooling chamber, ultraviolet light irradiates the surface of the copper rod. The wax liquid on the surface of the copper rod glows due to the fluorescent agent. Multiple cameras observe the luminescence of the copper rod surface from different directions. After all the wax liquid containing the fluorescent agent in the liquid tank is sprayed, new wax liquid is injected into the liquid tank to continue the wax liquid spraying operation. When the camera observes the copper rod, if the surface of the copper rod glows evenly everywhere, the production device is working normally and the wax liquid is evenly distributed on the surface of the copper rod. If the surface of the copper rod glows unevenly, with some parts glowing brighter or weaker, the production device is working abnormally and it is necessary to check the abnormal conditions of the wax coating mechanism and the material mixing mechanism and perform repairs.
