- the sheet metal hub 42 can be rotated counter to a drive direction 98.
- the rotation of the sheet metal hub 42 causes the sheet metal hub 42 to slide with its edge of the centering bore 46 into the distance 28 between the shaped elements 22 and the abutment surface 30 of the driving flange 10 and can be secured against falling down by the shaped elements 22 in the axial direction.
- the rotation of the sheet metal hub 42 causes the hook-shaped extensions to be displaced into the arcuate, narrow regions 80 of the recesses 78 of the sheet metal hub 42.
- the metal plate 48 is moved by the clamping hooks 56 by non-illustrated inclined surfaces axially against the pressure of the leaf spring unit 58 in the direction 54 until bearing surfaces of the hook-shaped projections in the arcuate, narrow areas 80 laterally adjacent to the recesses 78 of the sheet metal hub 42 come to rest.
- arcuate grooves 66 are introduced into the contact surface 30 of the driving flange 10, on the lying on the support surface 30, unwanted particles can be conveyed to the outside of the driving device 12.
- a release button 92 is pressed in the axial direction 64.
- the release button 92 pushes the drive plate 96 in the axial direction 64, and the formations 86 of the drive plate 96 come with the lock pockets 88 into engagement.
- the drive shaft 16 is locked.
- the bolts 20 are in this case with the recesses 76 of the sheet metal hub 42 disengaged, and the sheet metal hub 42 can be rotated in the circumferential direction 52 until the clamping hooks 56 can slide through the recesses 78.
- the mold elements 22, 24 in this case reach into a corresponding position, and the sheet metal hub 42 can be removed in the axial direction 54.
