Abstract
Способ комбинированной высадки концов труб, преимущественно с удлиненной переходной зоной, включающий деформацию на прессе нагретого конца трубы в полости разъемной матицы за счет перемещения пуансона, осуществляемую за несколько операций, отличающийся тем, что первоначально осуществляю деформацию конца трубы с уменьшением только внутреннего диаметра высадки до величины 1,03÷1,07 от его заданного значения, при этом коэффициент усадки устанавливают из соотношения ! , ! где D - наружный диаметр трубы, мм; ! S - толщина стенки трубы, мм; ! lвн - длина внутренней переходной зоны высадки, мм. A method of combined upsetting of pipe ends, mainly with an elongated transition zone, including the deformation on the press of the heated pipe end in the cavity of the detachable matrix due to the movement of the punch, carried out in several operations, characterized in that the pipe end is initially deformed with only the inner diameter of the pipe being reduced to a value 1,03 ÷ 1,07 of its predetermined value, while the shrinkage coefficient is set from the ratio! ! where D is the outer diameter of the pipe, mm; ! S is the wall thickness of the pipe, mm; ! lvn is the length of the internal transition zone of the landing, mm
