Production of a hollow shaft, e.g. camshaft comprises pushing and positioning cams and/or machine parts on a shaft, placing an element in one end of the shaft, placing in a tool, closing the tool and pressing with a ram

摘要

Production of a hollow shaft (1) comprises pushing and positioning cams and/or machine parts on a shaft in a location and position related to their function, placing an element (5) with an approximately the same external diameter as the internal diameter of the hollow shaft in at least one end of the shaft, placing the shaft with the cams and/or machine parts and the inserted element in an HF tool (4), closing the tool and allowing a medium to act under high pressure in the shaft, and pressing a ram axially against one front face of the shaft to fill the mold with the medium. Preferred Features: A planar surface is produced on the closed end of the shaft by mechanical processing and forming an inner thread or bore in the surface.
