[0002] Copper busbar extrusion coating is mainly used to improve the anti-corrosion and mechanical properties of copper busbar. In the fields of electricity, electronics, communications, new energy vehicles, aerospace, etc., copper busbar is a conductive material. However, when exposed to air, copper busbar is susceptible to oxidation and corrosion, resulting in performance degradation. In order to solve this problem, an extrusion coating process is usually adopted, that is, a plastic layer is extruded and wrapped on the surface of the copper busbar to form a composite structure. This composite structure can not only improve the anti-corrosion performance of the copper busbar, but also enhance its mechanical strength and bearing capacity. Copper busbar extrusion coating can improve the anti-corrosion and mechanical properties of the copper busbar and extend its service life.

The setting of the reflux groove 322 and the reflux pipe enables the cooling water to circulate in the first constant temperature zone 32, ensuring the uniformity and stability of the copper busbar during the cooling process, avoiding the problem of local overheating or insufficient cooling, and further improving the production efficiency and product quality. The setting of the flow slope 323 and the first water circulation system 35 that supplies water from a high place to a low place enables the cooling water to be continuously cooled and shaped at a constant temperature on the surface of the copper busbar, which helps to uniformly cool and shape the insulating layer and improve the quality and performance of the insulating layer. The setting of the first constant temperature zone 32 can also effectively control the temperature of the cooling water, ensuring that the temperature of the cooling water is within an appropriate range, and avoiding damage to the copper busbar and the insulating layer due to excessively high or low temperatures.

[0055] A constant temperature shaping process for copper bar extrusion coating, comprising a constant temperature shaping device for copper bar extrusion coating; the constant temperature shaping process for copper bar extrusion coating is as follows: the copper bar enters the feed component 11 through unwinding, enters the feed cavity 112 through the feed port, and passes through the connecting component 12, the extrusion component 13, the locking component 14 and the discharge component 15 in turn, and the vacuum pipe 114 is connected to the vacuum pump to vacuum the feed cavity 112, so that the copper bar passing through the feed cavity 112 is vacuumed, the stress on the outer surface of the copper bar is eliminated, and the copper bar is centered and floated in the feed cavity 112. When the copper bar enters the extrusion component 13, the rubber is extruded and coated in the central floating state, so that the rubber is evenly coated on the outer diameter of the copper bar. After the extrusion is completed, the extruded insulating layer is shaped and then led out through the discharging component 15. After extrusion, it is shaped once in the cooling and shaping area. After the first shaping, the insulating layer is marked by the coding mechanism 2; then it enters the constant temperature shaping mechanism 3, and passes through the first constant temperature zone 32, the second constant temperature zone 33 and the third constant temperature zone 34 in turn. The temperature of the first constant temperature zone 32 is 50-60°C, the temperature of the second constant temperature zone 33 is 30-40°C, and the temperature of the third constant temperature zone 34 is 20-30°C. This process can eliminate the stress generated by the copper bar during the production process and improve the quality and stability of the copper bar. By vacuuming, the air and moisture on the inner and outer surfaces of the copper bar can be effectively removed, thereby reducing the possibility of stress generation. Secondly, this process can make the copper bar float in the center of the feeding cavity 112, ensure the position and stability of the copper bar, and improve production efficiency and product quality. Furthermore, the process of extrusion and rubber coating can make the insulation layer evenly coated on the outer diameter of the copper busbar, increase the density and uniformity of the insulation layer, and improve the insulation performance and electrical resistance. In addition, by shaping the insulation layer after extrusion and exporting it, the stability of the shape and size of the insulation layer can be guaranteed, further improving the quality and performance of the product. This process uses advanced temperature control technology during the extrusion and constant temperature shaping process, which can effectively reduce energy consumption and improve energy utilization efficiency. By controlling the temperature, time and pressure parameters of the extrusion and constant temperature shaping process, it can be ensured that the products produced have consistent quality and performance. Products after constant temperature shaping can better adapt to various environmental conditions and improve product performance and service life. After constant temperature shaping, the insulation layer of the product is more uniform and dense, which improves the added value of the product.
