The invention discloses a room-temperature drawing forming method for a thin titanium TC1 alloy convex curvature partition plate. The room-temperature drawing forming method comprises the steps that a basin-shaped symmetric part theoretical model is constructed in a CAD environment; establishing a basin-shaped symmetrical part unfolding blank under finite element simulation software; a drawing die structure is determined in the CAD environment, and the drawing die structure comprises a male die, a female die and a blank holder; drawing and forming; and annealing and correcting. According to the method, a large amount of trial and error cost is reduced, the manufacturing method limited by titanium alloy hot forming is solved, the machining period of a hot forming die and titanium alloy hot forming is shortened, the manufacturing cost is saved, and the method has high popularization value. The drawing forming method is high in universality, forming of a thin-wall TC1 titanium alloy convex curvature part can be
