Abstract

Способ подготовки мерных заготовок для изготовления многослойных труб, преимущественно обечаек, методом навивки полосы на полый сердечник, при котором полосу разматывают с рулона, правят, стыкуют конец предыдущего и начало последующего рулонов, обрезают продольные кромки и разрезают на мерные заготовки, равные длине полосы для одной обечайки, отличающийся тем, что, с целью повышения производительности изготовления многослойных труб, перед обрезкой продольных кромок участок полосы, являющийся началом мерной заготовки, нагревают и раскатывают на "клин".The method of preparation of dimensional blanks for the manufacture of multilayer pipes, mainly shells, by winding a strip onto a hollow core, in which the strip is unwound from a roll, rule, join the end of the previous one and the beginning of the subsequent rolls, cut the longitudinal edges and cut into dimensional blanks equal to the strip length for shell, characterized in that, in order to increase the productivity of manufacturing multilayer pipes, before trimming the longitudinal edges, the section of the strip, which is the beginning of the measured workpiece, is heated and opened Tyva to "wedge".
