Wing spar die

Abstract

The invention provides a wing spar die. The wing spar die is used for a forming process for the hot diaphragm of a wing spar made from a composite material. The wing spar die comprises a forming boss(1), a frame body (2) detachably arranged around the forming boss (1), and a filling block (3) arranged in the space formed by the forming boss (1) and the frame body (2), and the shape of the fillingblock (3) is matched with the shape of the space, so that the filling block (3) fills the space; and the upper surfaces of the frame body (2) and the filling block (3), and the upper surface of the forming boss (1) are located on the same plane. According to the wing spar die provided by the invention, the problems of large location error, dead-weight deformation and the like of a flat prepreg plate in location and movement processes in the forming process for the hot diaphragm are solved, the uncertainty influence brought by the movement of the flat prepreg plate is reduced, and the locationaccuracy and stability of the flat prepreg plate in the location and movement processes are guaranteed; and moreover, the die is scientific and reasonable in structure, and the combined detachment manner of the whole die is reasonable and easy to use, so that the use convenience of the die is improved, and the die is safe and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of mechanical devices and transportation, in particular to a spar mold. Background technique [0002] Thermal diaphragm forming process: refers to the use of automatic tape laying or manual laying process to lay prepreg laminates for preforms, such as figure 1 As shown, the prepreg flat plate 5 is clamped between the superplastic membranes 6, the inside of the diaphragm is vacuumed, the temperature is raised, and the vacuuming operation is performed to make the prepreg layers slide, deform and stick to the mold, and finally the prepreg is laminated. To the surface of the mold, the preforming process is completed and the preform is prepared. [0003] Preform: A structure consisting of prepreg plies that have undergone the preforming process. The preform has a similar geometry to the final part. For complex parts, it can be assembled from different secondary preforms, or can be composed of secondary preform...
