The invention discloses a molybdenum crucible dual-wheel dip separation thermal state power spinning forming device. The molybdenum crucible dual-wheel dip separation thermal state power spinning forming device comprises a shaping system, two sets of spinning forming systems and two sets of automatic online heating systems; the two sets of spinning forming systems are distributed on the two sidesof the shaping system in an axial dip separation mode, and the two sets of automatic online heating systems are distributed on the two sides of the shaping system correspondingly; and the shaping system is used for shaping of a molybdenum board, the spinning forming systems are used for pressure applying forming of the molybdenum board, and the automatic online heating systems are used for heatingthe molybdenum board in the spinning forming process. According to the molybdenum crucible dual-wheel dip separation thermal state power spinning forming device, the molybdenum board can be adopted as a raw material, and a molybdenum metal rotary body product with the large length-diameter ratio, the variable section and the curved bus shape is prepared continuously at a time; and the circumferential wall thicknesses of a molybdenum crucible prepared through a spinning forming method of the device are consistent, the wall thicknesses in the height direction are uniform in thinning transition,the precision is accurate, cracks are avoided, and surface defects are avoided.
