旋压工艺的基本原理是将被加工的金属板料套在芯模上,芯模随主轴旋转,一个或几个旋轮沿芯模移动,旋轮加压于板坯,利用金属的塑性,逐点将金属板料加工成所需的空心回转体零件。旋压分普通旋压和强力旋力。只改变板坯形状而其壁厚不变(或有微量变薄)的旋压称为普通旋压;改变板坯形状又减薄壁厚的旋压称为强力旋压。国内外在导弹火箭方面用来旋压发动机壳体;航 The basic principle of spinning process is to be processed sheet metal set in the mandrel, the mandrel with the spindle rotation, one or several rotating wheel along the mandrel movement, rolling wheel pressure on the slab, the use of metal plasticity, Pour the sheet metal into the required hollow rotor parts. Spinning sub-ordinary spinning and powerful spin. Only change the shape of the slab and its constant wall thickness (or a slight amount of thinning) of the spin called ordinary spin; change the shape of the slab and thinning the wall thickness of the spin called strong spinning. At home and abroad in the missile rocket used to spin the engine shell; Air
