From the principle and process of continuous extrusion deformation, it can be seen that compared to traditional processes, continuous extrusion has the following advantages:
1. The forming process is hot extrusion plastic forming, which can reduce the impact of surface defects and mechanical damage of raw materials on product quality. The product surface will not produce defects such as warping and burrs that are easily found in traditional process methods, making the copper busbar have good surface quality.
2. When the copper bus bar is continuously extruded, the copper billet is under the three-way compressive stress condition of high temperature and high pressure in front of the extrusion die mouth, the original internal Casting defect of the copper rod, such as pores, shrinkage porosity, etc., can be cleaned in the continuous extrusion process, instead of the drawing process. Due to the role of its axial tensile stress, the copper bus bar produced by the expansion of the transverse defects can obtain excellent performance
3. Due to the special thermal deformation process of continuous extrusion, the produced copper busbar has very fine grain size and dense internal structure.
4. Eliminating the annealing process not only saves electrical energy but also avoids product performance changes caused by uneven furnace temperature during the annealing process, ensuring that the product's performance is uniform and consistent throughout the entire length, making it easy to meet the impedance matching requirements of transformers, motors, etc.
5. The optimized mold material and structure can ensure that the product has high dimensional accuracy, not only meeting the requirements of national standards and IEC standards, but also ensuring that the same batch of products have the same size and performance.
6. Due to the cancellation of the annealing process, the production cycle has been significantly shortened.
7. There will be no environmental pollution generated during the production process.
8. The entire production line adopts advanced computer control systems, which enables the automation of equipment during the production process, improves the stability and reliability of production line operation, and reduces the labor intensity of operators.
