Receiving device (10) for receiving a mandrel and a sleeve of a forming tool (12) for expanding an aperture (18), comprises a housing having a mandrel receptacle and a sleeve receptacle. The mandrel receptacle is displaceable in an axial direction. The mandrel receptacle and sleeve receptacle is formed for receiving mandrel (14) and sleeve (16) in the housing, such that the center axes of the mandrel and sleeve are coaxially aligned with each other. The mandrel- and the sleeve receptacle are constructed to move the mandrel and the sleeve with respect to each other and to the housing.
