摘要

Aluminum alloy drill pipe used in deep drilling has great potential and broad field of application. Unlike steel drill pipe production method, aluminum alloy drill pipe is manufactured using forward extrusion in the horizontal hydraulic extrusion press to extrud internal/external upset ends with variable cross-section, and form an assembly line to produce aluminum alloy drill pipe. In this experiment, using 55MN double-action extrusion press on 7075 aluminum alloy tubing to get variable cross-section on one-shot, the extruded pipe body are in good surface quality wihtout cracks, laying the foundation for the forming technology of variable cross-section of aluminum alloy drill pipe.
