Abstract
A method for producing a joint outer part by means of flow forming may involve positioning a blank on a contour mandrel such that the blank cannot rotate with respect to the contour mandrel, driving the contour mandrel such that the blank and the contour mandrel rotate about a common axis, and shaping the blank at least partially with the aid of a flow forming roller that acts on the blank to form the joint outer part. Further, shaping the blank at least partially with the aid of the flow forming roller may comprise forming at least one track with a concave region in the joint outer part.

A method for producing a joint outer part by way of flow forming, the method comprising:
- positioning a blank on a contour mandrel such that the blank is prevented from rotating with respect to the contour mandrel;
- driving the contour mandrel such that the contour mandrel and the blank rotate about a common axis;
- and
- shaping the blank at least partially with the aid of a flow forming roller that acts on the blank to form the joint outer part that includes a track with a concave region.
A joint outer part comprising a track with a concave region, wherein the track is produced by positioning a blank on a contour mandrel such that the blank is prevented from rotating with respect to the contour mandrel, driving the contour mandrel such that the contour mandrel and the blank rotate about a common axis, and shaping the blank at least partially with the aid of a flow forming roller that acts on the blank to form the joint outer part that includes the track with the concave region.
A tool for producing a joint outer part by way of flow forming, the tool comprising:
- a contour mandrel for receiving a blank in a manner such that the blank is prevented from rotating with respect to the contour mandrel;
- a drive for driving the contour mandrel such that the blank and the contour mandrel are rotatable substantially about a common axis;
- and
- a flow forming roller that acts on the blank to form a track with a concave region in the joint outer part.
