Problems solved by technology

Once the hole is deviated, it will cause the whole line to stop, which not only greatly increases the production cost of the product, but also seriously hinders the normal production. At the same time, it will cause a large safety hazard due to repeated feeding.
Partial hole products not only affect the quality of the product, but also pose a great safety hazard during use

Abstract

The invention discloses an extrusion forming method for an energetic material with non-circular deformed inner holes. The extrusion forming method is applied to forming and producing different types of energetic material products. The extrusion forming method sequentially comprises the following steps: adding 0.2-0.5 mass percent of zinc stearate into the energetic material to be processed; plasticizing by a plasticizer, uniformly mixing and granulating at the temperature of 90-97 DEG C; removing water from granules by a hot air drying machine at the temperature of 80-90 DEG C while heating the granules to be more than 70 DEG C; further plasticizing and extruding by a extruding machine at the temperature of 65-80 DEG C, and forming a finished product in a mold at the temperature of 70-80 DEG C. The extrusion forming method is a method capable ofr greatly increasing the feeding qualification rate of the extruded product with the non-circular deformed inner holes.

Description

technical field [0001] The invention is applied to molding and producing different types of energetic material products; it is widely applicable to the production of system products such as QXHJ, HJZCD, ZSDD, ZLDD and HTYTJJ. Background technique [0002] During the molding process of non-circular special-shaped inner hole products, it is very easy to have partial holes when feeding. Once the hole is deviated, it will cause the whole line to stop, which not only greatly increases the production cost of the product, but also seriously hinders the normal production, and at the same time, a large safety hazard is formed due to repeated feeding. Partial hole products not only affect the quality of the product, but also pose a great safety hazard during use. Therefore, how to adjust and improve processing materials and processes to solve the problem of partial hole has become a problem that urgently needs research and development.
