Abstract
Способ высадки концов труб, включающий несколько последовательных операций нагрева конца трубы и его деформации пуансоном в полости разъемной матрицы высадочного пресса, отличающийся тем, что вторую операцию высадки проводят с использованием матрицы и пуансона тех же размеров, что и в первой операции высадки, при этом величину усадки во второй операции определяют из соотношения, где ΔS - величина отклонения толщины стенки трубы; D - номинальный наружный диаметр трубы; S - номинальная толщина стенки трубы.A method of upsetting pipe ends, including several successive operations of heating the end of the pipe and its deformation by a punch in the cavity of the split die of the upsetting press, characterized in that the second upsetting operation is carried out using a matrix and a punch of the same size as in the first upsetting operation, the value shrinkage in the second operation is determined from the relation, where ΔS is the deviation of the pipe wall thickness; D is the nominal outer diameter of the pipe; S is the nominal wall thickness of the pipe.
