强力旋压机通常采用液压随动系统控制旋轮按样板作仿形运动,见图1。旋压开始前,工件毛坯尚未装上时就要调整机床:由样板控制旋轮作空负荷仿形运动,预调定旋轮与模胎之间的间隙为t′。然后,将厚度为t_0的毛坯送入,旋压成厚度为t的工件。实测工件壁厚得知,t>t′,即工件壁厚比预留的间隙增大了。其差值δ=t—t′即为旋轮受旋压力作 Powerful spinning machine usually adopts the hydraulic servo system to control the rotary wheel according to the template for the copying motion, as shown in Fig. 1. Before the start of spinning, the workpiece blank has not been loaded, it is necessary to adjust the machine: the model control rotary load sharing copying motion, pre-set the gap between the roller and the mold tire as t ’. Then, the thickness of t_0 into the rough, spinning into the thickness of the workpiece t. Measured workpiece wall thickness that, t> t ’, that is, the workpiece wall thickness than the reserved gap increased. The difference δ = t-t ’is the rotation of the spinning wheel by the pressure
