Abstract
1. Способ изготовления труб (4; 104) со стыковым швом из металлических листов (3), в частности, из толстых металлических листов, при котором металлический лист подают на трубоформовочный пресс (1), в котором его, с расположением лежа на нижнем штампе (6), с помощью поднимаемого и опускаемого верхнего штампа (9) под действием усилия гибки поступательно формуют в трубу (4; 104) со стыковым швом, имеющую противолежащие продольные кромки с зазором (11; 111) для последующей прямошовной сварки, отличающийся тем, что вначале получают трубу со стыковым швом некруглой черновой формы (13), для чего по меньшей мере на одном этапе гибки, действующей на внутреннюю сторону металлического листа (3), соответственно, слева и справа относительно середины, заданной продольной осью верхнего штампа (9), погружающегося в поступательно формируемый металлический лист (3), осуществляют меньшую формовку по сравнению с другими этапами гибки, после чего под действием усилия (F) закрытия, целенаправленно действующего снаружи на некруглую черновую форму (13) соответственно на ранее менее отформованных участках (12а, 12b) по обе стороны от середины, отформовывают готовую трубу (104) со стыковым швом.2. Способ по п.1, отличающийся тем, что некруглую черновую форму (13) на этапе изготовления перед воздействием усилия (F) закрытия позиционируют путем вращения по часовой стрелке или против часовой стрелки.3. Способ по п.2, отличающийся тем, что менее отформованный участок (12b) справа от середины поворачивают в положение примерно на три часа, а менее отформованный участок (12а) слева от середины - в положение примерно на девять часов.4. Устройство для изготовления труб (4; 104) со стыков�1. A method of manufacturing pipes (4; 104) with a butt seam from metal sheets (3), in particular from thick metal sheets, in which the metal sheet is fed to a pipe forming press (1), in which it is lying on the lower die (6), with the help of a raised and lowered upper stamp (9), under the action of a bending force, they are progressively molded into a pipe (4; 104) with a butt weld having opposite longitudinal edges with a gap (11; 111) for subsequent longitudinal welding, characterized in that that at first they get a pipe with a butt weld a rough draft form (13), for which at least at one stage of bending, acting on the inner side of the metal sheet (3), respectively, left and right relative to the middle defined by the longitudinal axis of the upper stamp (9), immersed in the translationally formed metal sheet (3), they perform smaller molding compared to other bending stages, after which, under the action of the closing force (F), which purposefully acts externally on the non-circular draft form (13), respectively, in previously less formed sections (12a, 12b) on both Oron from the middle otformovyvayut finished tube (104) with butt shvom.2. A method according to claim 1, characterized in that the non-circular draft form (13) at the manufacturing stage is positioned before closing (F) by closing it clockwise or counterclockwise. The method according to claim 2, characterized in that the less-formed portion (12b) to the right of the middle is rotated to a position of about three hours, and the less-formed portion (12a) to the left of the middle is turned to a position of about nine hours. Device for manufacturing pipes (4; 104) from joints�
