Description

Изобретение относитс  к сварке и может быть использовано дл  изготовлени  сварных пр мошовных труб из металлических и неметаллических матери- алов.The invention relates to welding and can be used for the manufacture of welded straight-flow pipes from metallic and non-metallic materials.

Целью изобретени   вл етс  интенсификаци  процесса нагрева путем увеличени  площади контакта между вращающейс  вставкой и кромками штрипса. The aim of the invention is to intensify the heating process by increasing the contact area between the rotating insert and the edges of the strip.

На фиг. 1 изображена схема процесса изготовлени  пр мошовных труб сваркой трением; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1,FIG. Figure 1 shows a schematic of the process for the manufacture of conduit pipes by friction welding; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one,

На фиг. 3 прин ты следующие обозначени : ti, - угол схождени  кромок штрипса (град); t - рассто ние между распорной шайбой и вращающейс  вставкой (мм); S - толщина расйорной шай- Вы (мм).FIG. 3 The following notation is used: ti, is the angle of convergence of the strip edges (degrees); t is the distance between the spacer washer and the rotating insert (mm); S is the thickness of the rasier belt (mm).

Формирование кромок штрипса и создание угла охлаждени  их в горизонтальной плоскости распорной шайбой, равного углу скоса вращающейс  встав- ки, позвол ет максимально увеличить площадь контакта между вращающейс  шайбой и кромками штрипса, что в свою очередь обеспечивает максимальную интенсивность нагрева кромок и, соответственно , повьш1ает производитель- ность процесса в целом.Shaping the edges of the strip and creating a cooling angle in the horizontal plane with a spacer washer equal to the bevel angle of the rotating insert maximizes the contact area between the rotating washer and the edges of the strip, which in turn ensures maximum heating intensity of the edges and, accordingly, increases - ness of the process as a whole.

Предлагаемый способ осуществл етс  следующим образом.The proposed method is carried out as follows.

Штрипс 1 задают в формовочные валки 2, где он формуетс  в трубу 3, затем сформованную трубу 3 прижимными валками 4 прижимают к формующему диску 5, где за счет выбора определенной толщины S формующего диска 5 обеспечиваетс  угол об схождени  кромок штрипса, равный углу скоса кромок сварочного диска 5. При трении кромок штрипса о кромки сварочного диска 6, происходит разогрев кромок штрипса, которые под действием давлени  сварочных валков 7 свариваютс . Св арочный диск 6 приводитс  во вращение двигателем 8.The strip 1 is set into the forming rolls 2, where it is molded into the tube 3, then the formed tube 3 is pressed against the forming disc 5 by the pressure rolls 4, where, by choosing a certain thickness S of the forming disc 5, the angle of the strip edges is equal to the angle of the bevel of the welding edges disk 5. When the edges of the strip rub against the edges of the welding disc 6, the edges of the strip heat up, which are welded under the pressure of the welding rolls 7. The arch disc 6 is driven by the motor 8.

И р и м е р, В лабораторных услови х была проведена сварка 60 труб диаметром 33 мм с толщиной стенки 1,5 мм из стали марки 08Х18Т1. При зтом расчетноеIn addition, in the laboratory, 60 pipes with a diameter of 33 mm and a wall thickness of 1.5 mm from steel grade 08X18T1 were welded. When this is calculated

усилие прижати  кромок штрипса к сварочному дис.ку составило 5 кгс/мм. Угол скоса кромок сварочного диска oi бып выполнен равным 10 . Формующий- диск размещали от сварочного диска на рассто нии 100 мм. Диаметры дисков бьши одинаковы и составл ли 500 мм. Толщину формующего диска выбирали из соотношени the force of pressing the edges of the strip to the welding disk was 5 kgf / mm. The bevel angle of the edges of the welding disc oi was equal to 10. The forming disc was placed from the welding disc at a distance of 100 mm. The disc diameters were the same and were 500 mm. The thickness of the forming disk was chosen from the ratio

S 2 tg ot/2, .S 2 tg ot / 2,.

при этом величина S составила 10 мм. За счет того, что угол схода кромок штрипса совпадал с углом скоса сварочного диска, площадь контакта достигала максимального значени  и разогрев их происходил более интенсивно (со скоростью 200 С/с, по сравнению с 170°С/с при известных способах) в св зи с чем скорость сварки увели- чилась до 7 м/с, по сравнению с 5,8 м/сек.while the value of S was 10 mm. Due to the fact that the angle of the edges of the strip coincided with the bevel angle of the welding disc, the contact area reached the maximum value and they were heated more intensively (at a speed of 200 C / s, compared to 170 ° C / s with known methods) due to with which the welding speed increased to 7 m / s, compared with 5.8 m / s.

Использование предлагаемого способа позвол ет повысить производительность известных способов производства пр мошовных труб из металлических и неметаллических (пластмассы, стекло и др.) материалов.The use of the proposed method allows to increase the productivity of the known methods for the production of conduit pipes from metal and non-metallic (plastics, glass, etc.) materials.
