针对磨球轧制机中斜轧轧辊螺旋孔型带有变高度、变螺距型槽的特点,以轧制准38mm磨球为例,阐述了利用Pro/E软件实体造型功能对轧辊的螺旋孔型进行实体建模的方法和步骤,克服了在轧辊传统设计中图形绘制复杂、无法直观体现轧辊实体、设计精度低等缺点,并为轧辊数控加工提供了理论依据。 In view of the characteristics of spiral groove with variable height and variable pitch groove in the milling ball mill, taking the rolling 38 mm ball as an example, the spiral hole of the roll is described by the solid modeling function of Pro / E software Type solid modeling methods and steps to overcome the traditional design of the roller graphic drawing complex, can not directly reflect the roll entity, the design accuracy and other shortcomings, and provides a theoretical basis for the roll NC machining.
