The invention provides an
aviation blade forming tool and a process based on a carbon-
ceramic material, and solves the problems of mold positioning eccentricity and difficulty in air film groove
machining after forming in the forming process by adopting an existing forming mold. A forming tool comprises an inner die, an outer die, a clamping plate
assembly and a limiting tool. The clamping plate
assembly is used for being matched with the inner die and the outer die to achieve positioning of the inner die and the outer die. The limiting tool is used for
machining an air film groove in the corresponding portion of the
fiber fabric in the process that the
fiber fabric is wrapped by the molded surface of the inner die. In the
machining process, the relative positions of the air film grooves and the relative positions of the air film grooves and the
fiber fabric are accurately positioned through the limiting tool, and blade scrapping caused by errors caused by manual measurement is prevented; the relative positions of the inner die and the outer die are fixed through the clamping plate
assembly, and the situation that due to relative sliding of the inner laminated and the outer die inthe forming process, the fiber fabric profile (wall thickness and curvature) is changed, and later blade machining
operability and blade performance are affected is prevented.
