铁丸依靠自重由抛丸器供丸管进入分丸轮后,迅速被高速旋转的分丸轮叶片卷起,并在离心力作用下沿着叶片向外运动,滑向定向套筒。由于定向套筒的限制,铁丸在分丸轮叶片外缘处积聚,形成团块。早先认为,铁丸团块的径向截面形状为一底和高均为a的三角形(图1),a值可由下列公式求得: s=(2θ/nibγ)~(1/2)米 (1)式中,Q——抛丸量,公斤/分; n——分丸轮转速,转/分; i——分丸轮叶片数; b——分丸轮叶片宽度,米; Iron pills rely on their own weight from the shot peening tube into the pill pill wheel, the rapid rotation of the sub-pill wheel rolled up, and in the centrifugal force along the blade outward movement, slip to the orientation sleeve. Due to the restriction of the directional sleeve, the iron pellet accumulates on the outer edge of the pellet wheel to form a mass. It has been previously thought that the radial cross-sectional shape of the iron pellets is a triangle having a bottom and a height a (Figure 1). The value of a can be obtained from the following equation: s = (2θ / nibγ) ~ (1/2) 1) Where, Q - shot blasting amount, kg / min; n - sub-pill wheel speed, rev / min; i--
