摘要

The process technology of overlength seamless aluminum tube indirect extrusion production was introduced.The fixed-mandrel extrusion process used for overlength seamless aluminum tube indirect extrusion production was researched by theoretical analyses, numerical simulation and experiment.The mechanics statue of mandrel in fixed-mandrel process was analyzed and the variation curve of pulling force on mandrel vs.ram displacement has been obtained.A technical route used for realizing overlength seamless aluminum tube indirect extrusion has also been put forward.The methods to reduce the eccentricity of overlength seamless aluminum tube indirect extrusion was put forward.The experiment research has been carried out on the 60 MN aluminum indirect extrusion press with oil-driven double action.
