早期的膨胀锥在应用于实体管膨胀时，不但需要较大的轴向力，而且存在套管膨胀后的轴向尺寸会有较大的减小等难题。
When the early expansion cone is used to expand solid expandable tubular, the great axial force will be needed and the length of the tube will be reduced considerably.
这锥是免费的轴向移动对抵抗的春天。
This cone is free to move axially against the resistance of a spring.
并分析了缩径率、缩径凹模半锥角、摩擦系数、缩径管坯初始壁厚对管端翘曲和轴向伸长率的影响规律。
In addition, this paper presents how the diameter reducing rate, the die semicone angle, the friction coefficient and the original wall thickness influence the buckling and the axial elongation rate.
