(54) Device for careful separation of anodes from their anode bars


(57) To create a mechanically operating device for the aluminium-producing industry by which not yet consumed anode blocks (10) that stick to the bottom end stubs (11, 12, 13) of an anode rod (15) by means of metal bushes (16) can be carefully separated from the anode rod, the invention proposes that the device features an impact fork (22) that can be moved upward and downward in the machine frame and which engages with its bottom prongs (20, 21) in the gaps between the anode rod yoke (14) and the upper side of anode block (10) with the impact stroke (24) of the impact fork corresponding to the distance between the fork prongs (20, 21) and the yoke underside (bottom position of the impact fork) and/or the distance between the yoke upper side and the underside of the impact fork mass body (22) (top position of the impact fork).
