An Investigation Concerning the Determination of Spinning Control Parameters for an Elliptical Boiler Head

椭圆封头仿形旋压法的技术难点是工艺控制参数的确定。文中分析了椭圆封头仿形旋压成形机理 ,建立了旋压轨迹方程 ,较系统地提出了控制封头旋压的渐开线仿形模板参数及旋压道次间距序列的确定方法 ,并成功地进行了工艺试验 ,为回转体的仿形 (或数控 )旋压控制参数的确定提供参考。

The technical difficulty of a profile spinning method for making elliptical boiler heads consists in the determination of relevant technological control parameters. On the basis of analyzing the forming mechanism of elliptical head profile spinning a locus equation for the spinning process has been worked out. Then, proposed in a relatively systematic way is a method for the determination of the following: the parameters of the involute profile form plate for the control of a boiler head spinning, and the spacing and sequence of the spinning process. This was followed by a successful technological test. The above information can serve as a guide during the determination of profile (or numerical control) spinning control parameters for other similar rotating bodies.
