(54) УСТРОЙСТВО ДЛЯ ОТБОРТОВКИ ОТВЕРСТИЙ(54) DEVICE FOR DRAWING HOLES
1one
Изобретение относитс к обработке металлов давлением и может быть использовано в устройствах дл отбортовки отверстий в трубах.The invention relates to the processing of metals by pressure and can be used in devices for flanging holes in pipes.
Известно устройство дл отбортовки отверстий в трубах, содержащее матрицу и соосно установленный с ней конус Г1.A device for flanging holes in pipes is known, which contains a matrix and a cone G1 coaxially mounted with it.
Недостатками указанного устройства вл ютс невозможность отбортовки отверстий на длинномерных изогнутых трубах, а также сложность конструкции.The disadvantages of this device are the impossibility of flanging the holes on long curved pipes, as well as the complexity of the design.
Цель изобретен-и - упрощение конструкции и обеспечение возможности отбортовки отверстий в длинномерных изогнутых трубах.The purpose of the invented-and-simplified design and ensuring the possibility of flanging the holes in long curved pipes.
Эта цель достигаетс за счет того, что устройство Дл отбортовки отверстий в трубах, содержащее матрицу и соосно установленный с ней корпус, снабжено двум цилиндрическими заглушками, соединенными между собой гибкими т гами и герметически установленными с обеих сторон от отверсти в матрице.This goal is achieved due to the fact that the device for flanging the holes in the pipes, containing the matrix and coaxially mounted with it, is provided with two cylindrical plugs interconnected by flexible drafts and hermetically mounted on both sides of the hole in the matrix.
Кроме того )3аглушки выполнены с заходыой конусной и дорнуюшей пипиндрической поверхност ми.In addition), the shears are made with the approach of the conical and dornashes of the pipindric surfaces.
На чертеже представлена конструкци устройства.The drawing shows the structure of the device.
Устройство состоит из двух заглушек 1 и 2 с уплотнени ми 3 и 4, матрицы 5, конуса 6, жидкостного пуансона 7, гибких т г 8, троса 9.The device consists of two plugs 1 and 2 with seals 3 and 4, a matrix 5, a cone 6, a liquid punch 7, flexible pipes, 8, a cable 9.
Устройство работает следующим обраo зом.The device works as follows.
В трубной заготовке Ю предвгфитедьно пробиваетс отверстие. Затем с помощью троса 9 обе заглушки 1 и 2 вт гиваютс внутрь длинномерной трубы 1О, In the pipe billet, Yu, a hole is presumed to be pierced. Then, using a cable 9, both plugs 1 and 2 are pulled inward into the long pipe 1O,
5 При этом происходит дорнование внутрен ней поверхности и устранение овальности сечени трубы. Так как диаметр заглушек на 2-5% больще внутреннего диаметра исходной заготовки, то стенки трубы .плотно облегают заглушки, обеспечива герметичность пространства между ними. С целью повышени надежности заглушки снабжают уплотнени ми 3 и 4. После5 When this occurs, the innerting of the inner surface and the elimination of the pipe cross section ovality occur. Since the diameter of the plugs is 2-5% larger than the internal diameter of the original billet, the pipe walls tightly fit the plugs, ensuring the tightness of the space between them. In order to increase reliability, the plugs are supplied with seals 3 and 4. After
