Description
Известны различные способы и соответствующие устройства дл Опрессовки концов трубок в трубных досках, преимущественно теплообменнИКов , в том числе и устройства с пуансонами, имеющими форму обратного конуса.Various methods and corresponding devices are known for crimping the ends of tubes in tube plates, mainly heat exchangers, including devices with punches having the shape of a reverse cone.
Однако Всем известным устройствам и приспособлени м присущи те или иные недостатки: применение значительного количества ручного труда, недостаточна производительность, необходимость предварительного нагрева концов трубок и высадка их во внутрь, недостаточна надежность запрессовки и др.However, all known devices and devices have certain drawbacks: the use of a significant amount of manual labor, insufficient productivity, the need to preheat the ends of the tubes and land them inside, insufficiently reliable pressing, etc.
Предложенное устройство исключает эти недостатки и обеспечивает механизацию большинства процессов по опрессовке концов трубок.The proposed device eliminates these shortcomings and provides for the mechanization of most of the processes for crimping the ends of the tubes.
Установка на золотниковом нереключателе рабочего цилиндра тарированного стопорного приспособлени .позвол ет автоматизировать регулирование давлени па внутренние стенки трубок в зависимости от толщины стенок и качества трубок.The installation on the spool non-switch of the working cylinder of a calibrated locking device makes it possible to automate the control of pressure on the inner walls of the tubes, depending on the wall thickness and the quality of the tubes.
Устройство представл ет собой конусную пружин щую цангу с надетым на нее пружин щим ограничительным кольцом. В цангу помещен стержень с обратным конусом, св занный со штоком рабочего гидроцилипдра.The device is a tapered spring collet with a spring ring attached to it. A reverse taper rod is placed in the collet, which is connected to the stem of the working hydraulic clip.
На чертеже изображен общий вид описываемого устройства. Удлиненна шестилепесткова цанга У, имеюща внутреннюю конусную поверхность, помещена в передней крышке 2 рабочего гидроцилиндра 3 и закреплена гайкой 4. Наружна цилиндрическа часть цанги имеет буртик Л, свободно опирающийс своими торцовыми поверхност ми с одной стороны на гай-ку 4, а с другой -на торцовую поверхность предохранительного пружин щего кольца 5, надетого на цангу и посто нно сжимающего ее.The drawing shows a General view of the described device. An extended six-petal collet U, having an inner conical surface, is placed in the front cover 2 of the working hydraulic cylinder 3 and secured with a nut 4. The outer cylindrical part of the collet has a shoulder L, freely supported by its end surfaces on one side to nut 4 and on the other on the end surface of the safety spring 5, worn on the collet and constantly compressing it.
При перемещении штока 6 гидроцилиндра вправо в том же паправлении перемещаетс св занна со щтоком конзсна т га 7, котора приWhen moving the rod 6 of the hydraulic cylinder to the right in the same direction, the coupling rod 7, which is connected with the rod, moves
