Description
УСТРОЙСТВО дл РАЗВАЛЬЦОВКИ ТРУБ ПРОТЯГИВАНИЕМDEVICE FOR RELEASE PIPES PROLASTING
Известны устройства дл развальцовки труб прот гиванием, включающие прот жную головку, выполненную в виде цилиндра с полым поршнем, в котором укренлена разжимна цанга, приводима в действие конусной оправкой, закрепленной на штоке рабочего поршн .Apparatuses for expanding pipes by pulling are known, including a pulling head made in the form of a cylinder with a hollow piston, in which a fastening collet is fixed, operated by a conical mandrel fixed to the stem of the working piston.
Предлагаемое устройство отличаетс от известных тем, что стыки разжимной секторной цанги выполнены с выступами и соответствующими им впадинами.The proposed device differs from the known ones in that the joints of the expandable sector collet are made with protrusions and their corresponding depressions.
Такое выполнение устройства обеспечивает получение безогранной развальцовки с одного перехода и улучшает качество развальцованной трубы.Such an embodiment of the device provides for obtaining a flareless flaring from a single junction and improves the quality of the flared pipe.
На фиг. 1 изображена конструктивна схема описываемого устройства; на фиг. 2 - разжимна секторна цанга соответственно до начала развальцовки и в момент развальцовки .FIG. 1 shows a structural diagram of the described device; in fig. 2 - expanding sector collet, respectively, prior to the beginning of flaring and at the time of flaring.
Прот жна головка устройства выполнена в виде цилиндра 1 с полым поршнем 2. В поршне укреплена разжимна цанга .3. Стыки разл имнои секторной цанги выполнены с выступами 4 и соответствующими им впадинами 5.The extension head of the device is made in the form of a cylinder 1 with a hollow piston 2. A compression collet is fastened in the piston .3. The joints of the races of the sector collet are made with protrusions 4 and their corresponding depressions 5.
Работа устройства. Подава рабочую жидкость в полость А цилиндра, перемещают поршень с разлшмной секторной цангой до упора поршн в крышку 6 цилиндра. При этом разжимна цанга, выт гива сь из трубы 7, производит ее развальцовку.The operation of the device. Supply the working fluid in the cavity A of the cylinder, move the piston with the universal sector collet until the piston stops in the cylinder cover 6. At the same time, the collet, pulled out of pipe 7, expands it.
