Description

Technical Field

[0001] The present invention relates to an extrusion forming mechanism for superalloy seamless tubes. Background Art

[0002] A seamless tube is a long steel bar with a hollow cross-section and no seams around it; seamless tubes are made by piercing and extruding steel ingots or solid billets into billets, and are widely used as pipes for conveying fluids. Compared with solid steel such as round steel, when the bending and torsional strength are the same, the seamless tube is lighter in weight and is widely used in the manufacture of structural parts and mechanical parts; existing seamless tubes are generally formed by an extrusion device, usually by extruding a billet located in a ingot cylinder with an extrusion block, so that the billet is extruded into an annular channel surrounded by an outlet die ring and an extrusion needle, and thus a hollow annular tube body is discharged to obtain a hollow seamless tube. However, in the actual production process, when seamless tubes with different strength requirements are to be processed, the wall thickness of the seamless tube needs to be adjusted. However, the existing extrusion device can only process and pressurize for one wall thickness, so the scope of use and flexibility are greatly limited. Summary of the Invention
