Abstract

Способ задачи полуцилиндрических трубных заготовок в сварочный стан, при котором производят сборку двух полуцилиндрических трубных заготовок, расформовку последних с помощью внутренней оправки, а также подачу их к сварочной клети и заформовку с обеспечением заданного угла схождения кромок перед сваркой, отличающийся тем, что, с целью повышения качества труб и уменьшения расходного коэффициента металла, собранные и расформованные полуцилиндрические трубные заготовки прижимают торцами продольных кромок к внутренней оправке с усилием, равным 0,2 - 0,8 усилия, создающего потерю устойчивости полуцилиндрических трубных заготовок или смятие кромок последних.The method of the task of semi-cylindrical billets into a welding mill, in which two semi-cylindrical billets are assembled, the latter are molded using an internal mandrel, and also fed to the welding stand and molded to ensure a specified angle of convergence of the edges before welding, characterized in that improve the quality of pipes and reduce the expenditure ratio of metal, assembled and deformed semi-cylindrical billets pressed ends of the longitudinal edges to the inner mandrel with effort, equal to 0.2 - 0.8 force, creating a loss of stability of semi-cylindrical tube blanks or crushing the edges of the latter.
