Description
Известен способ изготовлени труб, налример , толстостенных топливопроводных высокого давлени , путем холодной прокатки и последующего безо1правочного волочени до конечного размера.There is a known method of manufacturing pipes, nalimer, high-pressure thick-walled fuel pipes, by cold rolling and then without drawing to the final size.
Предлагаемый способ отличаетс от известного тем, что дл Повышени точности внутреннего диаметра и чистоты поверхности канала труб на минимальном технически возможном размере, ниже которого безоправочное волочение сопровождаетс утонением стенки, осуществл ют волочение на самоустанавливающейс оправке. Затем трубы снова подвергают безолравочному волочению до готового размера.The proposed method differs from that in that in order to increase the accuracy of the inner diameter and the cleanliness of the pipe channel surface, at a technically minimum size below which uncoupling drawing is accompanied by wall thinning, they are drawn on a self-aligning mandrel. Then the pipes are again subjected to a drawless drawing to the finished size.
Новый способ был опробован дл следующих размеров труб: 7x2,5 мм и 6X2,0 мм.The new method was tested for the following pipe sizes: 7x2.5 mm and 6x2.0 mm.
При испытании дл размера 7X2,5 мм была прим та следующа технологи :When tested for a size of 7X2.5 mm, the following technology was adopted:
14X2,8 мм - после холодной прокатки и безонравочного волочени , сопровождающегос утолщением стенки;14X2.8 mm - after cold rolling and unraveling drawing, accompanied by wall thickening;
10X2,65 мм - волочение на самоустанав .ливающейс оправке диаметром 4,7 мм;10X2.65 mm - drawing on a self-aligning mandrel with a diameter of 4.7 mm;
8X2,55 мм - волочение без оправки;8X2.55 mm - drawing without mandrel;
7X2,5 мм - волочение без оправки.7X2,5 mm - drawing without mandrel.
цеховых услови х по прин той на заводе технологии (отжиг, правжа, удаление окалины, нанесение покрыти и смазка).workshop conditions according to the technology adopted at the plant (annealing, grinding, descaling, coating and lubrication).
Дл задачи оправки в очаг дефор1мации иFor the task of the mandrel to the deformation zone and
удерл ани в нем до окончани волочени заднего конца трубы ее закрепл ли на стерл не . Дл задачи оправки з трубу задние торцы труб подрезали на станке. Угол конуса оправки составл л 9°. После волочени на оправкеI removed it in it until the end of the dragging of the rear end of the pipe, it was attached to the erased one. For the task of the mandrel with the pipe, the rear ends of the pipes were cut on the machine. The angle of the cone mandrel was 9 °. After dragging on the mandrel
трубы подвергали волочению без оправки до готового размера без промежуточных отжигов .pipes were drawn without a mandrel to the finished size without intermediate annealing.

Способ изготовлени труб, например, толсгостенных топливопроводных высокого давлени путем холодной прокатки и последующего безоправочного волочени , отличающийс тем, что, с целью повышени точности внутреннего диаметра и чистоты поверхности канала труб, на минимальном технически возможном размере диа-метра, ниже которого безоправочное волочение сопровождаетс утонением стенки, осуществл ют волочение на самоуста-навливающейс оправке, после которого трубы подвергают безоправочному волочению до готового размера.A method of manufacturing pipes, for example, high-pressure high-pressure fuel pipes by cold rolling and subsequent unwinding, characterized in that, in order to improve the accuracy of the inner diameter and the purity of the pipe channel surface, at the minimum technically possible diameter diameter, below which unwound drawing is accompanied by thinning the walls are dragged on a self-inflating mandrel, after which the pipes are subjected to a dragless drawing to the finished size.
