Description

Известны вальцовки дл  развальцовывани  концов труб, выполнен}1ые в виде устройства, имеющего конусные рабочие ролики, установленные на подвижном в осевом нанравлении наконечнике и обкатываемые но конусному элементу. Однако эти вальцовки не обеспечивают достаточной чистоты обрабатываемой поверхности. Предлагаема  универсальна  вальцовка позвол ет повысить чистоту обрабатываемой поверхности и тем улучшить герметичность соединени  труб при высоких давлени х. Это достигаетс  выполнением конусного элемента в виде вращающегос  конического ролика, опирающегос  основанием на шариковый упор.Rollers for flapping pipe ends are known, made in the form of a device having taper rollers mounted on a tip that is movable in axial direction and rolled around in a taper element. However, these rollers do not provide sufficient cleanliness of the treated surface. The proposed universal rolling improves the cleanliness of the treated surface and, thus, improves the tightness of the connection of pipes at high pressures. This is achieved by making the tapered element in the form of a rotating tapered roller, supported by a base on a ball stop.

На чертеже изображена .предлагаема  универсальна  вальцовка дл  развальцовывани  концов труб в разрезе.The drawing shows a proposed universal rolling for flapping the pipe ends in a section.

Основными рабочими органами вальцовки  вл ютс  конусные рабочие ролики /, установленные на подвижном в осевом направлении наконечнике 2 и обкатываемые по конусному элементу. Последний выполнен в виде вращающегос  конического ролика 3, опирающегос  основанием на щариковый упор 4.The main working bodies of the rollers are the tapered working rollers / mounted on the axially movable tip 2 and run on the tapered element. The latter is made in the form of a rotating tapered roller 3, supported by the base on the ball stop 4.

Труба, у которой развальцовываетс  конец, вставл етс  в разъемную цангу 5 и зажимаетс  в ней. Вращением воротка 6 с включенным храповым механизмом 7 производ т перемещение наконечника 2 в осевом направлении, а затем п1П1вод т последний во вращение. При этом ролики /, враща сь, развальцовывают конец трубы. Эти переходы (перемещение и последующее вращение наконечника) производ т несколько раз до получени  необходимого размера развальцованного конца трубы и требуемой чистоты поверхности.The pipe, at which the end is flared, is inserted into the split collet 5 and clamped therein. By turning the knob 6 with the ratchet mechanism 7 turned on, the tip 2 is moved in the axial direction, and then the latter is turned into rotation. In this case, the rollers /, rotating, flare the end of the pipe. These transitions (movement and subsequent rotation of the tip) are performed several times to obtain the required size of the flared end of the pipe and the required surface cleanliness.
