Abstract
A process for producing a hollow monoblock shaft from a pipe, the pipe initially having a constant diameter and a constant wall thickness, and the monoblock component including at least one area of its length being of a smaller outside diameter and a greater wall thickness than the constant diameter and constant wall thickness of the pipe. The process can be carried out simply and economically by the following process steps: selecting a pipe with a wall thickness which corresponds to the smallest wall thickness of the finished component, partial heating of at least one area of the pipe, axial upsetting the heated area of the pipe and radial forging the heated area of the pipe.

A process for producing a rotationally symmetrical component from a pipe, wherein the pipe has a constant outside diameter and a constant wall thickness, and the rotationally symmetrical component has an outside diameter of at least one portion of the length of the component which deviates from the constant outside diameter of the pipe and a wall thickness which deviates from the constant wall thickness of the pipe, comprising the steps of:
- selecting a pipe having a constant wall thickness which corresponds to the smallest wall thickness of the finished rotationally symmetrical component,
- partially heating at least one portion of the length of the pipe,
- axial upsetting the heated portion of the pipe, and
- radial forging the heated portion of the pipe to form the at least one portion of the rotationally symmetrical component.
A process for producing a rotationally symmetrical component from a pipe, wherein the pipe has a constant outside diameter and a constant wall thickness, and the rotationally symmetrical component has an outside diameter on at least one portion of the length of the component which deviates from the constant outside diameter of the pipe and a wall thickness which deviates from the constant wall thickness of the pipe, comprising the steps of:
- selecting a welded pipe that has not been redrawn having a particular wall thickness, and
- working at least one portion of the pipe by means of rotary swaging at room temperature to form the at least one portion of the rotationally symmetrical component.
