The Research Of Designing And Manufacturing Of A Kind Of Environmental Protection Type Of The Cartridge Case Of Fireworks

The traditional cartridge case of fireworks adopts the paper of yellow board as the raw material. If we use the paper of yellow board to produces the cartridge case of fireworks, a lot of paper must be consumed, and roughly 1/3 of the paper of yellow board as the side and comer can't be used, so the cost of production is very high. Environmental protection type of the cartridge case of fireworks is a kind of patented product which adopts fibrous powder of plants, such as straw, the grass of wheat, haulm of corn, and the side and corner of paper that have been used as the raw material. This kind of material is called environmental protection type of paper pulp.Some research work have been finished as following:The material properties of environmental protection type of the cartridge case of fireworks studied, the mechanical function parameters are received. After its diameter and thickness effecting to the loading capacity studied by finite element method (FEM), the formula of relation is researched firstly.A kinds of new technology, which use molding tool to produce environmental protection type of the cartridge case of fireworks with high quantity, high-efficiency and low cost, have been invented by practicing again and again, so the problem of producing of the traditional cartridge case of fireworks, such as low quantity, low-efficiency and high cost, has been solved.The dies for producing environmental protection type of the cartridge case of fireworks have designed and manufactured according to the change of technology. The whole set of molding tool consists of the percolate mold, cold press mold and the heat press mold. The molding tools are designed by using the designing tool of CAD/CAM software (such as Master CAM), and then produce CNC work program of manufacturing of the molding tools by using the CAM software of it aftergiving the correct tool path, after that producing the molding tools by using the CNC machine tools.Having been finished, the molding tool can largely produce the newly product of environmental protection type of the cartridge case of fireworks of high quality, low price and strong market competition ability by examining of actual production and resolving the problem of appearing in it, coming to the anticipant design purpose.Finally, testing the properties of environmental protection type of the cartridge case of fireworks to insure that it can satisfy the requirement of designing of products.A kind of patent design has been become newly environmental protection product of having vast market foreground by research work, and filled up the local blank.
