Description

Technical Field

[0001] The utility model relates to the technical field of new energy copper busbar conductor production, in particular to a copper busbar extrusion production line. Background Art

[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. In addition, with the improvement of environmental awareness, the application of halogen-free low-smoke extruded materials is becoming more and more widespread. It not only has good flame retardant properties, but also can reduce the risk of fire. Therefore, the application prospects of copper busbar extrusion coating process are very broad. The existing extrusion process can only complete simple extrusion coating and cooling shaping, but the copper busbar needs to be electrically tested when it is produced into a product. The existing ones are tested after the product is made, and cannot be tested during the extrusion shaping process. Utility Model Content

During the shaping process, three groups of constant temperature zones are used, corresponding to each water circulation system. The water circulation system controls the water temperature to a certain temperature and then flows to shape and cool the insulation layer of the copper bar. The shaping effect is good. After shaping, the shaped insulated copper bar is formed. The insulated copper bar is sent to the electric measurement mechanism for electrical testing to detect whether there is a problem of insufficient coating of the insulation layer. After detection, it passes through the pressing and cutting mechanism and enters the winding mechanism for material collection. When the pressing and cutting mechanism detects that the insulation coating is not in place, the part is pressed and fixed and then cut. The problem of the existing copper bar production not being continuous is solved, and the automation of copper bar extrusion, coding, shaping, detection, and cutting is realized, with high production efficiency.

[0030] A vacuuming structure is provided on the feeding component of the extrusion structure to vacuum the copper bar passing through the feeding cavity, eliminate stress when the copper bar enters the extrusion component, and at the same time, the insulation layer is coated with high precision and good coating effect during extrusion. The problem of poor extrusion effect of the existing copper bar is solved. The precision and stability of the extruded insulation layer are improved, thereby improving the overall performance and product quality of the copper bar.

[0031] The feeding assembly is designed to be detachable and installable, which facilitates the feeding and discharging of the copper bar, and also facilitates the replacement of the copper bar and the mold. The feeding sleeve is provided with a feeding cavity, one end of the feeding cavity is provided with a feeding port, and the other end is provided with a guide port. This design allows the copper bar to enter the feeding cavity smoothly, avoiding the copper bar from getting stuck or deformed during the extrusion process. At the same time, the design of the guide port also ensures the stability and uniformity of the copper bar during the extrusion process, which is conducive to the uniform distribution of the extruded insulation layer.

[0032] The connecting component serves as a bridge between the feeding component and the extrusion component, playing an important role in connection and support. Through reasonable structural design, the feeding cavity and the extrusion component are closely connected, ensuring the continuity and stability of the copper busbar during the extrusion process. At the same time, the vacuum pipe set in the connector is used to vacuum the copper busbar passing through the feeding cavity. This design is not only conducive to removing air and impurities inside the copper busbar, but also makes the vacuum extrusion more uniform and stable.

[0033] As a key processing equipment, the extrusion component can realize the molding and shaping of the copper busbar extrusion insulation layer. It uses a professional extrusion die and heating system, so that the extruded insulation layer can be quickly cooled and formed. The extrusion component of the device has high precision and high stability, which can ensure that the thickness, uniformity and smoothness of the extruded insulation layer meet the expected requirements.

[0034] The function of the locking assembly in the device is to ensure that the copper bar remains stable during the extrusion process and prevent the copper bar from displacement or offset during the extrusion process. At the same time, the locking assembly can also effectively protect the copper bar from wear and damage of the extrusion equipment. The discharge assembly is responsible for outputting the processed copper bar for subsequent processing and utilization.

[0035] As mentioned above, the utility model can realize accurate control of the extruded insulation layer of the copper busbar, and improve the accuracy and stability of the extruded insulation layer. Secondly, the device simplifies the process flow of copper busbar processing, and improves production efficiency and product quality. Finally, the device also has high safety and reliability, and can ensure safety and stability in the production process. These technical effects not only improve the overall performance and product quality of the copper busbar, but also provide strong support for the development of the copper busbar processing field.

[0036] Copper busbar extrusion process, this process can eliminate the stress generated by the copper busbar during the production process and improve the quality and stability of the copper busbar. By vacuuming, the air and moisture on the inner and outer surfaces of the copper busbar can be effectively removed, thereby reducing the possibility of stress. Secondly, this process can make the copper busbar float in the center of the feeding cavity, ensure the position and stability of the copper busbar, and improve production efficiency and product quality. Furthermore, the process of extrusion and encapsulation 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, 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 increases the added value of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] The constant temperature shaping process of copper bar extrusion coating includes a copper bar extrusion production line; the constant temperature shaping process of 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 extrusion coating is carried out in a floating state in the center, so that the extruded coating 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 discharge 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.
