Abstract
The invention discloses a free filling type metal wire embedded solid propellant forming device and process, and belongs to the field of solid propellants, the free filling type metal wire embedded solid propellant forming device comprises a bottom plate, a base, a mold cylinder and a top cover are sequentially arranged on the bottom plate, and a plurality of pressing structures are arranged on the upper portion of the top cover; a solid propellant coating barrel is arranged on the inner wall of the mold barrel; the lower end of the metal wire is fixed on the bottom plate, the upper end of the metal wire is fixed on the first fastener of the fastener mounting block on the top cover, and the first fastener is screwed into the threaded hole, so that the metal wire can be tensioned, and the internal stress of the metal wire can be adjusted by adjusting the expansion amount of the metal wire; according to the invention, the collimation of the metal wire in the propellant is ensured, the proper stress of the metal wire in the slurry casting process is also ensured, the problem that the metal wire is broken due to overlarge stress is avoided, and the technical problem that the yield of the solid propellant is low due to the fact that the metal wire is easy to break in the propellant in the prior art is solved.
