环保型礼花弹壳模具的CAD/CAM

CAD/CAM of Molding Tools of Environmental Protection Type of the Cartridge Case of Fireworks

用稻草、麦杆等农业废弃物来生产环保型礼花弹壳是一种专利设想。通过改革生产工艺,然后根据工艺要求用CAD设计出生产用模具,并用数控机床把模具制造出来,再用模具生产出具有很好的经济效益和社会效益的环保型新产品是非常有价值的。

It was a kind of patent design consideration that the environmental protection type of the cartridge case of fireworks was made by using the wastes after agriculture such as straw, the grass of wheat. It is very valuable that the environmental protection type of the cartridge case of fireworks which had a very nice economic and social benefit was made by the molding tools for producing which were made by improving the technology of producing, and then designing them by using the tool of CAD according to the technology, and manufacturing them by using CNC machine tools.
