Изобретение относитс к области обработки металлов давлением.This invention relates to the field of metal forming.
Известен способ изготовлени труб с винтовым гофром путем воздействи гибкого элемента на вращающуюс трубу.There is a known method of manufacturing pipes with a screw corrugation by acting on a flexible element on a rotating pipe.
Однако известным способом могут быть получены только сравнительно невысокие гофры на трубах конечной длины.However, in a known manner, only relatively low corrugations on pipes of finite length can be obtained.
С целью обеспечени непрерывного процесса образовани гофра по предложенному способу воздействие на трубу осуществл етс несколькими гибкими элементами, линейна скорость каждого из которых равна произведению окружной скорости трубы на ее радиус под соответствующим элементом.In order to provide a continuous process of corrugation according to the proposed method, the impact on the pipe is carried out by several flexible elements, the linear velocity of each of which is equal to the product of the peripheral speed of the pipe and its radius under the corresponding element.
На фкг. 1 схематично изображено устройство дл осуществлени предлагаемого способа; на фиг. 2 - схема установки гибких элементов, число которых зависит от высоты формуемого гофра.On fkg. Figure 1 shows schematically an apparatus for carrying out the proposed method; in fig. 2 - installation diagram of flexible elements, the number of which depends on the height of the formable corrugation.
Трубки / устанавливаютс на оправку 2 с профилированными роликами 3, захлестывают несколькими одновитковыми гибкими нит ми 4, располага их по винтовой линии против роликов 3.The tubes / are mounted on the mandrel 2 with the profiled rollers 3, are overwhelmed with several single-turn flexible threads 4, arranged in a helix against the rollers 3.
Затем производ т поочередное нат жение и перемещение вокруг трубки гибчих нитей так, чтобы величина тангенциальной деформации (глубина врезани в трубку каждой нити) оставалась примерно одинаковой, а скорость перемещени возрастала от нити к нити по мере уменьщени диаметра трубки.Then alternate tension and movement of flexible threads around the tube are performed so that the value of tangential deformation (depth of penetration into the tube of each thread) remains approximately the same, and the speed of movement increases from one thread to another as the diameter of the tube decreases.
Трубка под действием нитей получает поступательное и вращательное движение, при этом за счет уменьшени тага винтовой линии на оправке уменьшаетс шаг гофра на трубке до величины готового гофра.The tube under the action of the filaments receives translational and rotational motion, and by reducing the helix tag on the mandrel, the corrugation pitch on the tube is reduced to the size of the finished corrugation.
Предмет изобретени Subject invention
Способ изготовлени труб с винтовым гофром путем воздействи гибкого элемента на вращающуюс трубку, отличающийс тем, что, с целью обеспечени непрерывного процесса образовани гофра, воздействие на трубу осуществл етс последовательно несколькими гибкими элементами, линейна скорость каждого из которых равна произведению окружной скорости трубы на ее радиус под соответствующим элементом.A method of manufacturing pipes with screw corrugations by applying a flexible element to a rotating tube, characterized in that, in order to ensure a continuous process of forming a corrugation, the pipe is subjected to successively several flexible elements, the linear velocity of each of which is equal to the product of the peripheral speed of the pipe by its radius under the corresponding element.
