Abstract
In a flaring tool for hollow, especially hollow-cylindrical, workpieces, a flaring punch is mounted for axial displacement in a tool body and can, by means of a cam on a hand level, be driven out of the tool body against a set of flaring dies fastened to the tool body. To solve the problem of being able to withdraw the flaring dies from the workpiece quickly enough to prevent the workpiece from quickly shrinking on the flaring dies, the flaring punch is coupled to the hand lever by an extractor whose point of engagement with the hand lever is excentric from the fulcrum axis. The extractor consists advantageously of at least one flat link which is journaled at one end on the hand lever and at the other end on the flaring punch.
