Abstract: The present disclosure provides a rotary extrusion forming method for a cabin section workpiece, comprising the following steps of: first preparing a hollow truncated cone-shaped blank; heating the prepared blank to a molding temperature and holding, and preheating a female die and a male die to above the molding temperature and holding; assembling an upper die assembly on a press; applying lubricant on the female die and the male die, and placing and fixing the blank into a die cavity of the female die; starting up a rotation driving device to drive the female die to rotate on a lower die base, so that the female die drives the blank to rotate; starting up the press to make the male die move down to a machining position of the blank in the female die cavity through the upper die assembly, and machining inner side walls of the blank.

Abstract: The present disclosure provides an extrusion forming die for a cabin component. The extrusion forming die for a cabin component comprises an upper die assembly, a lower die assembly and a combined concave die. The upper die assembly comprises an extrusion punch (3), and the combined concave die comprises an M-shaped outer concave die (4) having a hollow cavity matched with the extrusion punch (3), and a W-shaped inner concave die (5) having a rotary cavity. The W-shaped inner concave die (5) is arranged in the rotary cavity of the M-shaped outer concave die (4) in a matched manner, and the rotary cavity and the hollow cavity are matched to form a rotary extrusion die cavity (18) with a W-shaped longitudinal section.
