This method uses a tool head (such as a ball-ended metal rod) to continuously and progressively extrude the local area of the tube end, gradually extending and shaping the material. Its greatest advantage is that it requires less forming force and can effectively prevent common defects such as wrinkling and cracking in thin-walled tubes during processing. It is particularly suitable for flanging thin-walled metal tubes.
This process involves applying a huge axial pressure to the end of a tube at room temperature or low temperature through a die, causing the metal to flow within the die cavity, thereby thickening, expanding, or forming a specific shape (such as a flange). It is a non-cutting plastic processing method.
This type of technology focuses on the overall or partial bending and forming of tubes, used for manufacturing conduits with complex spatial orientations. Modern techniques have achieved integrated bending, cutting, and measurement for highly efficient forming, significantly enhancing precision and efficiency.
Aerospace and aviation: This is one of the fields with the highest technical requirements. It requires the processing of complex space tubes made of high-temperature alloys, titanium alloys, and other materials. The tubes must maintain extremely high inner wall smoothness and cross-sectional accuracy even under extremely small bending radii to ensure the absolute safety of fuel and hydraulic systems.
· Energy equipment and nuclear power: Whether it is the heat exchanger support profiles for the "Hualong One" nuclear power plant or the giant copper crystallizers for 100-ton electroslag furnaces, they all rely on high-performance tubes and tube end forming technologies. High-performance copper tubes can increase the service life of crystallizers by 3 to 5 times, saving hundreds of millions of yuan annually.
· Rail transportation and heavy machinery: Precision tube end forming parts used in the manufacturing of braking systems and hydraulic pipelines require extremely high fatigue strength and sealing reliability. The multi-step upsetting and extrusion process provides a forging-level connection solution for the braking systems of railway freight cars.
· Major infrastructure projects: Super-large diameter thick-walled spiral welded pipes are used in bridge pile foundations, artificial island cofferdams, deep-sea pipelines, etc. The forming and welding quality of the pipe ends directly affects the safety and lifespan of the overall structure.
