Claims (6)

1. Способ прессовой формовки стальной трубы из стального листа, включающий в себя:1. A method of extruding a steel pipe from a steel sheet, including: многократную прессовую гибку стального листа для образования открытой трубы для ее формирования в стальную трубу;multiple press bending of the steel sheet to form an open pipe for its formation into a steel pipe; при этом заранее получают зависимость между величиной дополнительного вжатия, которое дополнительно требуется после образования заданного зазора между кромками в процессе прессовки при последнем применении прессовой гибки открытой трубы, и заданным зазором между кромками, при этом величина зазора между кромками в состоянии снятия прижимающей нагрузки после последнего вжатия является равномерной,in this case, a dependence is obtained in advance between the amount of additional compression, which is additionally required after the formation of a predetermined gap between the edges during pressing during the last application of press bending of an open pipe, and a predetermined gap between the edges, while the size of the gap between the edges in the state of removal of the pressing load after the last compression is uniform причем прессование при последней прессовой гибке применяется к открытой трубе с последующей величиной дополнительного вжатия, основанной на указанной зависимости, после образования заданного зазора между кромками в процессе прессовки при последнем применении прессовой гибки,moreover, the pressing at the last press bending is applied to the open pipe with the subsequent value of the additional compression, based on the specified dependence, after the formation of a given gap between the edges in the pressing process with the last use of press bending, 2. Способ по п. 1, в котором заданный зазор между кромками является зазором между кромками в момент, когда открытые края стального листа входят в контакт со штангой пуансона верхней части штампа.2. The method according to claim 1, in which the specified gap between the edges is the gap between the edges at the moment when the open edges of the steel sheet come into contact with the rod of the punch of the upper part of the stamp. 3. Способ производства стальной трубы, включающий в себя этапы, на которых соединяют друг с другом несоединенные кромки открытой трубы, формованной способом по любому из пп. 1 или 2, и сваривают несоединенные кромки друг с другом.3. A method of manufacturing a steel pipe, comprising the steps of connecting the unconnected edges of an open pipe, molded by a method according to any one of paragraphs, to each other. 1 or 2, and unconnected edges are welded together.
