发明名称 FLARING TOOL FOR HOLLOW WORKPIECES
摘要 A flaring tool (1) for hollow workpieces having a basic tool body (2) with an expanding mandrel (13), which can be displaced by means of a drive. A supporting device (5) concentrically surrounding the expanding mandrel with an exchangeable expansion head (6) which has radially movable expanding jaws (14) located in a screw cap (16). The supporting device (5) is placed in the basic tool body (2) and can be moved longitudinally by means of a threaded extension (8) in the direction of the (A-A) axis of the expanding mandrel (13), and has an annular flange (11) which serves as a stop (10) for the expansion head. The supporting device (5) is fixed opposite the basic tool body (2) by means of a stopping device. In order to achieve a simple, reliable and reproducible set-up the supporting device (5) has in its annular flange (11), in a circle placed concentrically to the (A-A) axis, index boreholes for an index pin (29), located in the basic tool body (2).
