Claims (1)

i - , .- , -,. :. поверхностей цилиндрического 4 и конического 5 каналов. Труба, нагреваема  с помощью нагревател  11, входит в конический ка нал 5. При этом ее наружна  поверхность обжимаетс  матрицей и становит с  конической. По мере продвижени  трубы в канал матрицы толщина стенок трубы увеличиваетс . Недеформируема  часть трубы посто нно охлаждаетс . На конце 13 трубы, соприкасающемс  с торцом 9 пробки 8, толщина ее сте ки больше, чем толщина стенки недеформированной части трубы. Коническа часть трубы ограничиваетс  коническо поверхностью 14 матрицы, угол наклон которой соответствует углу наклона поверхности канала 5, и стенкой 15 с большим углом наклона. Дальнейша  подача трубы 12 осущес вл етс  при закрытой пробке 8 хвосто вика, при этом конец 13 трубы не перемещаетс , а происходит наращивание металла и увеличение толщины конической стенки 15. Подачу трубы заканчивают при получении требуемой толщины стенок. Затем пробку 8 удал ют вручную или автоматически. Например, она снимаетс , когда усилие на торец 9 пробки со стороны конца 13 трубы 12 превышает заданное, или по истечении определенного времени. Подачу трубы 12 продолжают, и металл стенки 15 образует цилиндрический наконечник 16, причем толщина его стенок точно равна толщине стенки в месте перехода конической части трубы в цилиндрическую часть наконечника. Прекращают подачу трубы 12, когда получают наконечник необходимой длин Она может точно соответствовать длин цилиндрического канала 6, Готова  труба имеет цилиндрическу часть, толщина стенки которой равна толщине стенки первоначальной трубы 12, коническую часть, толщина стенки которой возрастает, и цилиндрическую часть или наконечник Г, толщина стенок которого равна наибольшей толщин ртенок конической части. Таким образом можно получить деталь , внутренний диаметр узкой части которой мал по сравнению с диаметром широкой части, Внутренний диаметр узкой части может равн тьс  нулю без какого-либо нарушени  структуры металла и/или состо ни  поверхности. На внутренней поверхности цилиндрического наконечника может быть в дальнейшем нарезана резьба, а другой конец трубы 12 может быть обра- . ботан таким же образом дл  получени  второго наконечника. Однако резьба может быть получена на последней стадии процесса обработки в предложенном устройстве (см. фиг.7-9). При этом матрица имеет центральный стержень 17. Его, например, ввод т после того, как удал етс  пробка 8. На внешней поверхности стержн  17 выполнена нарезка 18. При подаче коническа  часть трубы входит в пространство между стержнем 17 и внутренней поверхностью канала 6. Образуетс  цилиндрический наконечник с резьбой, при этом и стержень вовлекаетс  в движение. По достижении нужной длины наконечника стержень 17 выкручиваетс  из готового наконечника с резьбой. Формула изобретени  Устройство дл  обжима концов металлических труб, преимущественно тонкостенных цилиндрических труб большой длины, содержащее нагреваемую матрицу, в которой перед конической полостью выполнена цилиндрическа  полость, и смонтированный со стороны последней цилиндрический .охлаждаемый направл ющий блок, отличающеес  тем, что, с целью повьниенй качества обработанных труб, упом нутый блок установлен вплотную к цилиндрической поверхности матрицы. Источники информации, прин тые во внимание при экспертизе 1. Сб.трудов МАТИ, вып.65, Новое в технологии штамповки , М., Машиностроение, 1966, с.54, рис,7,i -, .-, - ,. :. surfaces cylindrical 4 and conical 5 channels. The pipe being heated by means of the heater 11 enters the conical channel 5. At the same time, its outer surface is compressed by the matrix and becomes conical. As the pipe moves into the die channel, the thickness of the pipe walls increases. The non-deformable part of the tube is continuously cooled. At the end 13 of the pipe in contact with the end face 9 of the plug 8, the thickness of its stack is greater than the wall thickness of the non-deformed part of the pipe. The conical part of the pipe is limited by the conic surface 14 of the matrix, the slope of which corresponds to the angle of inclination of the surface of the channel 5, and the wall 15 with a large angle of inclination. Further supply of the pipe 12 is carried out with the tailing cap 8 closed, while the end 13 of the pipe does not move, but the metal builds up and the conical wall 15 increases. The supply of the pipe is completed when the required wall thickness is obtained. The plug 8 is then removed manually or automatically. For example, it is removed when the force on the end 9 of the plug on the side of the end 13 of the pipe 12 exceeds the predetermined one, or after a certain time has passed. The supply pipe 12 continues, and the metal wall 15 forms a cylindrical tip 16, and the thickness of its walls exactly equal to the wall thickness at the junction of the conical part of the pipe in the cylindrical part of the tip. Stopping the supply of pipe 12 when the tip of the required length is obtained. It can exactly correspond to the length of the cylindrical channel 6, the finished pipe has a cylindrical part, the wall thickness of which is equal to the wall thickness of the original pipe 12, a conical part whose wall thickness increases, and a cylindrical part or tip G, the wall thickness of which is equal to the greatest thickness rtenok conical part. Thus, it is possible to obtain a part whose inner diameter of the narrow part is small compared with the diameter of the wide part. The inner diameter of the narrow part can be zero without any disruption of the metal structure and / or surface condition. On the inner surface of the cylindrical tip can be further threaded, and the other end of the pipe 12 can be reversed. botan in the same way to get a second tip. However, the thread can be obtained at the last stage of the processing process in the proposed device (see Fig.7-9). In this case, the matrix has a central rod 17. It is, for example, inserted after the plug 8 is removed. Cutting 18 is made on the outer surface of the rod 17. When fed, the conical part of the pipe enters the space between the rod 17 and the inner surface of the channel 6. a cylindrical threaded tip, and the rod is also involved in the movement. Upon reaching the desired tip length, the rod 17 is twisted out of the finished threaded tip. The invention of the device for crimping the ends of metal pipes, mainly thin-walled cylindrical pipes of great length, containing a heated matrix in which a cylindrical cavity is made in front of a conical cavity, and a cylindrical cooled guide block mounted on the side of the latter, characterized in that the treated tubes, said block is installed against the cylindrical surface of the die.
