Abstract
An aspect of the present invention relates to a method and a forming machine for working a workpiece, for example by deforming it or fixing it in another workpiece, in which the workpiece is fitted over a mandrel, at least a part of the mandrel is expanded so as to fix the workpiece, the workpiece and at least one tool, such as a forming roller, are rotated about an axis relative to each other and the workpiece is worked by means of said tool. The mandrel includes a stop adapted to engage the workpiece to obtain a desired axial position on the mandrel.
Claims13
A forming machine for working a workpiece, the forming machine comprising:
- a tool adapted to perform work on a workpiece;
- a mandrel having an at least partially expandable part adapted to hold the workpiece, and wherein the mandrel includes a stop adapted to engage the workpiece to obtain a desired axial position on the mandrel;
- and
- a drive coupled to at least one of the mandrel and the tool and adapted to rotate at least one of the mandrel and the tool relative to each other about an axis.
A forming machine for working a workpiece, the forming machine comprising:
- a tool adapted to perform work on a workpiece;
- a mandrel having an at least partially expandable part adapted to hold the workpiece, and wherein the mandrel includes a stop adapted to engage the workpiece to obtain a desired axial position on the mandrel, and wherein the mandrel includes at least one bracket arranged along a circumference of the mandrel, the at least one bracket being rotatable about a point between its ends;
- and
- a drive coupled to at least one of the mandrel and the tool and adapted to rotate at least one of the mandrel and the tool relative to each other about an axis.
A method for working a workpiece, comprising:
- fitting the workpiece over a mandrel wherein fitting includes abutting the workpiece with a stop of the mandrel to obtain a desired axial position of the workpiece on the mandrel, and wherein the mandrel includes at least one bracket arranged along a circumference of the mandrel, the at least one bracket being rotatable about a point between its ends;
- rotating the at least bracket of the mandrel so as to fix the workpiece thereon;
- rotating at least one of the workpiece and a tool relative to each other about an axis;
- and
- working a portion of the workpiece with the tool.
