冷态旋转锻造是一种高精度的无切削加工工艺,锻后无飞边或少飞边,光洁度和生产率均高,并可加工一般切削机床难以加工的特殊工件。本文介绍了该厂旋转锻造设备的机构原理、工件冷锻的应力应变分析以及圆锥变形角、模具圆弧半径的选取。本文还介绍了一种针形工件的试验过程和工艺参数以及该厂应用冷态旋转锻造的实例。 Cold rotary forging is a high-precision non-cutting process, after forging without flash or less flash, finish and productivity are high, and can be processed general machining difficult to machine special workpiece. This paper introduces the mechanism of the plant rotary forging equipment, the workpiece cold forging analysis of stress and strain as well as the cone angle, the radius of the mold selection. This article also introduced a needle-shaped workpiece test process and process parameters and the application of the factory cold forging example.
