Forming Of Magnesium Alloy Rear Drum

According to an important cooperation project of North University of China and Shanxi Machinery Group—to reduce the weight of current using steel rocket tail; And the same time to improve the properties of the barrel;In this paper, according to their existing equipment and assembly requirements, mold are designed choosing the lightest weight, hardness materials;It is important to improve the mechanical properties to meet the use requirements through a reasonable forging methods.Arrow missile is coming main weapons under high-tech conditions of local war, reducing weight, improving flying arrows play speed and distance is the development direction of weapons and equipment research and countries. And reducing weight to arrow missile structure growth range is the effective way to realize the aim.Lghtest lightweight magnesium alloy, the lightest structural materials is the preferred alternative materials to reduce the structural weight of the missiles.However, for the rocket tail and the tail tube and other key piece of missiles, Conventional forming of magnesium alloy is difficult to achieve its performance targets, can not meet their conditions of service.Therefore,it is urgent to develop new magnesium ally forming method.According to the forming tail barrel features:1,The shape of the parts is very complicated,convex sets must be pre-machined in the barrel due to the installation of its leaves;2,The hole inside of the part is large and the wall thickness is relatively small,so the deformation is very large;3,The working environment is in a highly rotating, thereby the deman of the mechanical properties of the barrel is high;To study the forming process of such parts is meaningful to improve its performance.There are four provisional craft; Studying the feasibility of each technology through the simulation and choosing the best one of them; then the structure of mole and parameters of forging are also optimized through simulation, Finally reasonableness of the craft are verified through experiment.
