AI Technical Summary
In existing technologies, the connection between branch pipes and main pipes has poor strength, welded connections are prone to leakage, the metal deformation during cold extrusion is uneven, it is difficult to apply to high-strength alloy materials, and the forming efficiency is low, limiting its applicability.
The branch pipe is formed at high temperature by using a wall thickness thickening device and a wall thickness radial extension forming device. The wall thickness thickening mold and the radial extension mold are used to form a continuous metal matrix. Combined with a vibration impurity removal mechanism, the oxide scale is removed, so as to realize the integral forming of the branch pipe and the main pipe.
It achieves high-strength integrated molding of branch pipes and main pipes, avoiding defects in welded joints, with good metal fluidity and high molding precision, suitable for high-strength alloy materials, reducing processing costs and the risk of fluid leakage.
