ABSTRACT:
The invention relates to a method of producing a divided tube stabilizer having a swivel motor (2) mutually coupling two tube stabilizer halves (3, 4), a first tube stabilizer half (3) being non-rotatably connected with a first connection part (5) of the swivel motor, and a second stabilizer half (4) being non-rotatably connected with a second connection part (6) of the swivel motor (2). In order to achieve that the tube stabilizer halves can be easily linked in a non-rotatable manner with the connection parts of the swivel motor, the following process steps are suggested:a. The tube ends to be connected with the connection parts (5, 6) of the swivel motor (2) are expanded and upset in one working step by means of a mandrel (20);b. the tube stabilizer halves (3, 4) with the expanded and upset ends are shaped to their final shape by bending;c. the finished bent tube stabilizer halves (3, 4) are subjected to a heat treatment;d. the expanded and upset tube ends of the heat-treated tube stabilizer halves (3, 4) are material-lockingly connected with the respective connection parts (5, 6) of the swivel motor (2).
