Zusammenfassung:	The utility model relates to an elephant-foot-free isostatic pressing die device which comprises a columnar metal core rod, a rubber sleeve arranged on the metal core rod in a sleeved mode and a rubber cover assembly arranged on the metal core rod in a sleeved mode and used for sealing the two ends of a target tube cavity, and the rubber cover assembly comprises a rubber cover and a rubber ring piece. A target tube cavity is formed between the rubber sleeve and the metal core rod, the rubber ring piece is arranged on the metal core rod in a sleeved mode and located in the target tube cavity, the rubber ring piece is provided with a deformation cavity and a deformation area which elastically deforms in the direction of the deformation cavity, the deformation area faces the target tube cavity, and the rubber cover is connected to one end of the metal core rod and abuts against the rubber ring piece. In the isostatic pressing machining process of the rotary sputtering target blank, the deformation cavity can ena
