Description

Technical Field

[0001] This application relates to the field of metal extrusion molding, and in particular to a copper busbar extrusion molding apparatus and extrusion molding process. Background Technology

[0002] Copper busbars are important conductive components in power equipment, power transmission and distribution systems, and complete electrical installations, and are widely used in transformers, switchgear, distribution cabinets, and busbar systems. Copper busbars are typically characterized by large cross-sectional dimensions, high conductivity requirements, and strict requirements for surface quality and dimensional accuracy. Their forming quality directly affects the safety, reliability, and service life of electrical equipment.

[0003] In existing technologies, copper busbar forming methods mainly include rolling, forging, and extrusion forming. Among these, extrusion forming is widely used because it can produce copper busbars with large cross-sectional dimensions, dense structures, and good mechanical properties in a single process. However, existing copper busbar extrusion forming equipment and processes still have certain shortcomings.

[0004] On the one hand, existing copper busbar extrusion equipment mostly relies on manual experience to control heating temperature, extrusion pressure, and extrusion speed, resulting in low automation levels. This leads to significant parameter fluctuations during extrusion, easily causing uneven internal structure and large dimensional deviations in the copper busbar, affecting the consistency and stability of the finished product. On the other hand, some equipment has unreasonable connections between the extrusion and cooling / shaping stages, resulting in low cooling efficiency or uneven cooling. This can easily cause warping, deformation, or even cracks on the surface of the copper busbar, reducing the product qualification rate.

[0005] In addition, existing copper busbar extrusion equipment is cumbersome to operate in terms of mold replacement and specification switching, making it difficult to meet the needs of multi-specification, small-batch production. Furthermore, it lacks integration in continuous material receiving, fixed-length cutting, and online inspection, often requiring multiple manual processes, resulting in low production efficiency, high labor intensity, and increased human error.

[0006] Therefore, there is an urgent need for a copper busbar extrusion molding device with a reasonable structure, high degree of automation, and stable molding accuracy, as well as a matching extrusion molding process, to achieve continuous, high-precision, and high-efficiency production of copper busbars, improve product quality and production reliability, and meet the growing technical demands of the modern power equipment manufacturing industry for copper busbar products.

Temperature equalization releases internal stress in the copper busbar, improving the mechanical properties and stability of the finished product. Material collection and inspection: The shaped copper busbars are collected by the material collection mechanism 603, and their dimensional accuracy and surface quality are inspected online. The copper busbars are continuously collected by the material collection mechanism, and the dimensional accuracy and surface finish of the copper busbars are monitored in real time by the online inspection system. The material collection mechanism ensures continuous collection and stable conveying of the copper busbars, avoiding dimensional deviations caused by manual handling and cutting.

Continuous production: The extrusion parameters are automatically adjusted based on feedback from the control system to achieve high-precision continuous production. Based on dimensional and surface quality data from online monitoring, the control system automatically adjusts extrusion parameters (such as pressure, speed, and temperature) to ensure consistency and stability during the copper busbar extrusion process. Through closed-loop control, any deviations during production can be adjusted promptly, ensuring consistent forming accuracy and surface quality of the copper busbars and preventing defective products. This process enables continuous production, improves production efficiency, reduces manual intervention, and enhances overall automation and production stability.

[0035] Example 1 This embodiment discloses a copper busbar extrusion molding apparatus. The apparatus includes an extrusion host 1, a heating device 2, a die assembly 3, a feeding mechanism 4, a control system 5, and auxiliary devices 6. The extrusion host 1 provides the driving force required for copper busbar extrusion.

The heating device 2 is located at the front end of the extrusion channel and includes an infrared heating unit 201 and a resistance heating unit 202, which can heat the copper material to a suitable plastic temperature, reduce extrusion resistance, and reduce molding defects such as cracks or uneven flow lines. The die assembly 3 includes an extrusion die 301 and a cooling die 302. The extrusion die 301 is used for preliminary shaping of the copper material, determining the cross-sectional shape and size of the copper busbar. The cooling die 302 is used for rapid cooling and shaping of the copper busbar, ensuring stable forming. The rapid cooling function of the cooling die can effectively improve production efficiency and avoid copper busbar warping or dimensional deviations. The feeding mechanism 4 works in conjunction with the extrusion host to ensure that the copper material is fed into the extrusion host evenly and continuously, avoiding fluctuations caused by uneven feeding. The control system 5 includes a temperature control module 501, a pressure control module 502, and a displacement control module 503, which adjust the temperature, pressure, and displacement parameters in real time during the extrusion process to achieve automated control and improve the forming accuracy and surface quality of the copper busbar. The auxiliary device 6 includes a lubrication device 601, a cleaning device 602, and a receiving mechanism 603.

[0036] Example 2 This embodiment discloses a copper busbar extrusion molding process. The process includes the following steps: First, copper material preparation involves cutting the copper material to a specified length and pre-cleaning it to remove the oxide layer and impurities from the surface, ensuring the copper material is clean and uncontaminated, providing a good foundation for subsequent processes. Next, a heating pretreatment is performed, where the copper material is heated to a suitable plastic temperature using a heating device 2. This heating process reduces the hardness of the copper material, improves its fluidity and plasticity, reduces frictional resistance during extrusion, ensures the copper material passes smoothly through the die, and avoids molding defects such as cracks or uneven flow lines. Then, the preheated copper material is fed into the extrusion host 1 and undergoes plastic deformation through the extrusion die 301 to extrude the copper busbar. The feeding mechanism 4 works in conjunction with the extrusion host 1 to ensure that the copper material is fed into the extrusion host uniformly and continuously, avoiding production fluctuations caused by uneven feeding, thereby ensuring the consistency and precision of the copper busbar molding. After extrusion, the copper busbars undergo rapid shaping and temperature equalization via a cooling mold 302. The cooling mold employs either water or air cooling to quickly cool the copper busbars and maintain their shape stability. This rapid cooling effectively prevents warping or deformation caused by uneven cooling, improving the mechanical properties and operational stability of the copper busbars. Subsequently, the copper busbars are continuously collected by a receiving mechanism 603 and subjected to online inspection to ensure that the dimensional accuracy and surface quality meet requirements. The online inspection system feeds back the inspection data to the control system 5 in real time. The control system automatically adjusts extrusion parameters, such as pressure, temperature, and speed, based on the feedback data to ensure high precision and stability in the extrusion process, preventing the generation of defective products and achieving high-precision continuous production of copper busbars. Through precise control of the above steps, this process can efficiently produce copper busbars and ensure the stability of forming accuracy, surface quality, and mechanical properties.
