本文从图解解析方法入手、研究分析在交叉轴情况下,斜轧管坯变形情况的空间几何关系,找出其内在规律,并据此提出合理的辊型设计方法,以改变目前辊型设计仍处于缺乏根据的盲目状态。文章给出基本几何形体的共轭回转面的作图法,并推导出它们的解析公式。这里的结论除应用于斜轧生产中之外,也适用于机械加工如磨削、铣削加工等。 This paper starts with the method of graphical analysis and studies the spatial geometry of the slab blank under cross-axis conditions to find out its inherent law. Based on this, a reasonable design method of the roll shape is proposed to change the design of the roll- In the absence of a blind basis. The paper gives the method of mapping the conjugate revolving surfaces of the basic geometries and derives their analytical formulas. The conclusion here is that it is suitable for machining such as grinding, milling, etc., in addition to being used in the production of slant rolls.
