Problems solved by technology

However, when the filling is completed, that is, when the mold cavity has been completely filled with powder, the separation of the feeding port of the silo and the feeding port of the elastic mold will inevitably bring about powder leakage and dust, which will virtually cause environmental pollution and increase cleaning and spillage. Operating procedures, while causing harm to the physical and mental health of operators
In addition, energetic material powders are usually composed of particles of different particle sizes. It is difficult to avoid particle size segregation in the vacuum adsorption feeding process applied in industry, which promotes the separation of powder particles, which is detrimental to its subsequent molding performance. influences

Abstract

The invention discloses an automatic compensation filling device for isostatic press moulding of energetic materials, and belongs to the technical field of energetic materials. The automatic compensation filling device comprises a rack, a material cylinder gripper assembly, a lifting material platform assembly, material cylinders, a lifting hopper assembly, a hopper, an elastic mould and a vibration platform, the lifting material platform assembly and the vibration platform are mounted in one side of the rack, the material cylinders are placed on the upper part of the lifting material platformassembly, the elastic mould is mounted on the vibration platform, the lifting hopper assembly is slidably mounted on the position, above the elastic mould, of the rack, the hopper is mounted on the lifting hopper assembly, a bottom discharging outlet of the hopper is opposite to a feeding inlet of the elastic mould, and the material cylinder gripper assembly is slidably mounted at the top of therack and used for gripping the material cylinders and moving the material cylinders to the position above a top falling opening of the hopper. The automatic compensation filling device is novel in structure, adopts a brand-new design mode, and realizes automatic feeding, falling and filling operation of the energetic materials, and the phenomena of dust raising and powder leakage in the filling process are effectively eradicated.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to an automatic compensating filler device for isostatic pressing of energetic materials. Background technique [0002] Compared with traditional energetic material molding products, isostatic pressing has unique advantages such as high and uniform product density and near-net molding. The basic principle is to place the powder energetic material pre-packaged in an elastic mold such as rubber or plastic in a closed container filled with liquid, and the deformation of the elastic mold when it is subjected to the pressure of the isotropic liquid medium is transmitted to the mold. Energetic material is powdered so that it can be compacted into a compact body or part with a certain density and strength. [0003] Since the surface of the outer mold is subjected to the same pressure during the isostatic pressing process, in order to avoid the uneven shrinkage of different par...
