A set of experiments was designed to study the relationship between expansion deformation force, axial length reduction, wall thickness reduction, tensile strength /yield strength of expansion pipe and model angle of expansion tool and expansion rate.
文中通过一组试验,比较详细地研究了膨胀管膨胀变形力、膨胀后套管轴向缩短量、膨胀后套管壁厚减小量、膨胀后套管的抗拉强度、屈服强度与膨胀工具模角及套管膨胀率的关系,得到了它们之间相互制约的变化规律。
In order to study the change of inner diameter of combination die for cold extrusion of spline when it is pushed into shrinkage ring, the relation curves between the moved distance along axis and the change of inner diameter of combination die was obtained through experimental method.
为研究花键组合凹模压入预应力圈时内径的变化规律,实验研究了轴向压合量对凹模内径变化的影响规律。
