Description

ленных на торцах оправки при помощп кронштейнов 7 и 8, причем один конец плаНки 5 выполнен без шарнира. Радиальное перемешение сегментов 4 ограничено кольцами 9 п 10. Оболочка 2 на стыках граней выполнена с цилиндрическими выступами И, а в зоне закреплени  планок5 и 6 - с сегментами 4 с наружными гофрами 12. Дл  сн ти  готовой детали с оправки у большого ее торца установлено кольцо 13 и винты 14 дл  его осевого иеремеш;ени . Зазоры между сегментами перекрыты планками 15.on the ends of the mandrel with the help of brackets 7 and 8, with one end of the plunk 5 made without a hinge. The radial mixing of segments 4 is limited to rings 9 and 10. The shell 2 at the junction of the faces is made with cylindrical projections And, and in the fastening zone of the slats 5 and 6 - with segments 4 with outer corrugations 12. A ring is installed at its large end face to remove the finished part from the mandrel. 13 and screws 14 for axial mixing. The gaps between the segments are covered with strips 15.

Работает оправка следуюш,им образом.The mandrel works in the following way.

После намотки ленточного материала на наружную поверхность оправки полость 3 подключают к источнику питани  и производ т подкачку рабочей жидкости. При этом оболочка 2 начинает раздуватьс  за счет деформации цилиндрических выступов 11, сегменты 4 получают радиальное перемешение, и наружный диаметр оправки увеличиваетс . Ограничительные кольца 9 и 10 у торцов оправки служат дл  фиксации конечного размера разжатой оправки. Причем при раздувании оболочки 2 ее пр молинейные грани опираютс  на сегменты 4, а в области жесткой заделки - на шарнирные планки 5 и 6. В местах неподвижного соединени  оболочки 2 с корпусом 1 шарнирные планки 5 и 6 имеют также нулевое перемеш,ение, чем обеспечиваетс  надежность креплени  оболочки 2. Увеличение диаметральных размеров оправки происходит только за счет деформации цилиндрических выступов 11, незначительна After winding the tape material on the outer surface of the mandrel, the cavity 3 is connected to a power source and the working fluid is pumped. In this case, the shell 2 begins to inflate due to the deformation of the cylindrical protrusions 11, the segments 4 receive a radial displacement, and the outer diameter of the mandrel increases. The limit rings 9 and 10 at the ends of the mandrel serve to fix the final size of the unclamped mandrel. Moreover, when the shell 2 is inflated, its straight edges rest on segments 4, and in the hard seal area - on the hinge bars 5 and 6. In the places of fixed connection of the shell 2 with the body 1, the hinge bars 5 and 6 also have zero mixing, which ensures reliability of fastening of the shell 2. An increase in the diametral dimensions of the mandrel is only due to the deformation of the cylindrical protrusions 11, insignificant

осева  деформаци  оболочки 2 происходит за счет поперечных гофр 12 у торцов оправки . Сн тие готовой детали с оправки производ т при помоши кольца 13 и перемещением винтов 14.axial deformation of the shell 2 occurs due to transverse corrugations 12 at the ends of the mandrel. Removing the finished part from the mandrel is done by using the ring 13 and moving the screws 14.

Применение предлагаемой оправки позволит обеспечить ее надежную работу при повышенных температурах и значительных удельных давлени х. The application of the proposed mandrel will ensure its reliable operation at elevated temperatures and significant specific pressures.
