叙述了半锥角 (α/2 )小于 1°锥筒的反旋成形过程 ,对铝合金大直径短锥筒与合金钢小直径长锥筒的变薄缩旋成形进行了试验研究 ,选择出不同规格锥筒反向变薄缩旋的工艺参数 ,探索了两种合金锥筒变薄缩旋的工艺路线 ,并旋出了样筒 ,为小角度无缝锥筒加工成形提供了参考
The anti-spin forming process of half-cone angle (α / 2) less than 1 ° cone was described. The thinning and shrinking forming of large diameter short cone of aluminum alloy and small diameter long cone of alloy steel were studied. Different specification conical tube reverse thinning and shrinking the process parameters to explore two kinds of alloy conical tube thinning and shrinking of the process line, and screw out the sample tube, which provides a reference for forming a small angle seamless cone
