Description

Technical Field

[0001] The invention relates to the technical field of copper material processing, and in particular to a device for continuous extrusion and equidistant expansion of special-shaped copper materials and a method for using the device. Background Art

[0002] Continuous extrusion and equidistant expansion of special-shaped copper materials is an advanced metal processing technology that achieves uniform expansion of the copper material cross section through a continuous extrusion process. This technology is usually used to manufacture copper products with specific cross-sectional shapes and size requirements, such as I-shaped, H-shaped or T-shaped copper materials. In the continuous extrusion process, the copper material is fed into the extruder and is continuously pushed forward in the die under high pressure. The die is designed to the desired final product shape, and the copper material gradually expands its cross section and forms equidistant intervals when passing through the die.

[0003] The advantage of continuous extrusion is that it can achieve high-efficiency production while ensuring the dimensional accuracy and surface quality of the product. In addition, this technology can also reduce material waste because it allows copper to be accurately formed without sacrificing material properties. During the continuous extrusion process, the microstructure of the copper material will also be optimized, thereby improving its mechanical properties, such as strength and ductility.

[0004] With the development of industrial automation and precision manufacturing technology, continuous extrusion equidistant expansion technology is increasingly used in aerospace, automobile manufacturing, building structures and other fields. By precisely controlling parameters such as extrusion speed, pressure and temperature, high-quality special-shaped copper materials that meet specific engineering needs can be produced.

[0005] However, when processing the existing I-shaped special-shaped copper materials, it is often necessary to cooperate with the welding process to obtain the copper materials in the special shape of the I-shaped copper materials. Once such cooperation is required, the structural strength of the special-shaped copper materials cannot be guaranteed. When they are used in scenes with high requirements for structural strength, the welding points will become the breaking points of the special-shaped copper materials, which will then cause the overall structure to fall apart.

[0006] Therefore, a device for continuous extrusion and equidistant expansion of special-shaped copper materials and a method for using the same are proposed to solve or alleviate the above problems. Summary of the invention

[0040] A limiting plate 12 between the intermittent pressurizing component and the continuous extrusion component is fixedly connected to the main bracket 2, and an I-shaped limiting groove for the copper material to pass through is provided on the limiting plate 12.

[0042] like Figure 3 As shown, the present invention also provides a method for using a device for continuously extruding and equidistantly expanding special-shaped copper materials, which is used to produce special-shaped copper materials, comprising the following steps:

[0043] Cut two copper strips of the same length and stack them up;

[0044] Overlap two copper strips and weld their two ends to obtain a temporarily combined copper material;

The fused copper material is fine-tuned in shape by the limit plate 12 to form a preliminary I-shaped structure. Finally, the continuous extrusion assembly applies continuous pressure to the temporary I-shaped copper material in a high-temperature state until it stably forms the required I-shaped copper material during the natural cooling process.
