Device for expanding conduits

摘要

The device (1) has a pin (7), which is axially and swivelably held in a housing (3) of a pressing device (2) or in a base body (5) fixable at the housing of the pressing device. The pin has a pin tip that is brought in contact with an expanding head (21). The pin and the expanding head are coupled by synchronization units that exhibit an O-ring (28) held in an annular groove (8a) of the pin and a magnet (29) held at the pin tip. The head has a nut extending in a longitudinal axis direction, and a pin-shaped designed synchronization unit stays in contact with the nut.
