Изобретение относитс к области трубоволочильного производства,This invention relates to the field of pipe-threading,
В известном устройстве дл раздачи труб волочением с одновременным обжатием по стенке подвижна оправка жестко закреплена на пр молинейных негибких стержн х. Однако это не позвол ет получить длинные трубы вследст вне значительного увеличени .арнтов стана и нежесткости длинного стержн , что вызывает вибрацию инструмента , привод щую к снижению качествА получаемых труб.In the known device for dispensing pipes by drawing while simultaneously squeezing along the wall, the movable mandrel is rigidly fixed to the straight and inflexible rods. However, this does not allow long pipes to be obtained due to a significant increase in the mill edges and non-rigidity of the long rod, which causes the tool to vibrate, resulting in a reduction in the quality of the pipes produced.
Предложенное устройство отличаетс тем, что оно снабжено т нущим барабаиом с гибким стержнем, на конце которого закреплена подвижна раздаюша оправка. Это позвол ет уменьшить габариты устройства при получении труб большой длины повысить качество труб.The proposed device is characterized in that it is provided with a tapping barbier with a flexible rod, at the end of which a movable distributing mandrel is fixed. This makes it possible to reduce the dimensions of the device when receiving pipes of long length to improve the quality of the pipes.
На фиг, 1, 2 и 3 показаны последо- вательные стадии работы предложенного устройства.Figures 1, 2 and 3 show the successive stages of operation of the proposed device.
Устройство содержит т нущий барабан 1, гибкий стержень 2, направл к « шие приводные ролики 3, трубную заготовку 4, промежуточный раздвижной захват 5 дл удержани заготовки, подвижную самоустанавливающуюс волоку 6, задний раздвижной захват 7, пробку 8 и раздаклдую оправку 9.The device comprises a drag drum 1, a flexible rod 2 directed to the drive rollers 3, tubular billet 4, intermediate sliding grip 5 for holding the billet, movable self-adjusting dies 6, rear sliding grip 7, stopper 8 and unfastened mandrel 9.
Устройство работает следующим образом . Трубна заготовка 4 подаетс на линию волочени и крепитс захватом 5. В закрепленную таким образом трубу вводитс посредством направл5поших приводных роликов 3 гибкий стержень 2, сматываемый с т нущего барабана 1 до выхода конца стержн из противоположного конца трубы. Затем на трубную заготовку с заднего конца надеваетс волока 6 на рассто ние, необходимое дл образовани захватки на заднем конце, трубы, а к концу гибкого стержн 2 крепитс раздающа оправка 9, После этого при помощи барабана 1 приводитс в дв жёвиеThe device works as follows. The tube blank 4 is fed to the draw line and secured by the catch 5. The flexible rod 2, which is wound up from the tapping drum 1 before the end of the rod ends from the opposite end of the pipe, is inserted into the pipe fixed in this way by means of the driving rollers 3. Then, a die 6 is put on the pipe billet from the rear end for the distance required to form the claw at the rear end, and the dispensing mandrel 9 is attached to the end of the flexible rod 2.
