Description

Известны устройства дл  правки труб и прутков, в частности машины с косо расположенными гиперболическими валками, на которых правка производитс  за счет знакопеременного изгиба, создаваемого смещенной парой холостых валков.Devices for straightening pipes and rods are known, in particular, machines with obliquely arranged hyperbolic rolls, on which the straightening is carried out by alternating bending created by an offset pair of idle rolls.

Однако на таких машинах не обеспечиваетс  правка по всей длине, так как передние и задние концы не прав тс  -на рассто нии , равном шагу .валковых обойм.However, such machines do not provide for editing along the entire length, since the front and rear ends are not right - as a distance equal to the pitch of the roller holders.

С целью повышени  точности правки по всей длине в предлагаемом устройстве опорный валок изгибающей обоймы выполнен вогнутым , а нажимной - выпуклым.In order to improve the accuracy of editing along the entire length in the proposed device, the support roll of the bending cage is made concave and the pressure roll is convex.

На чертеже схематично представлено описываемое устройство.The drawing schematically shows the described device.

Между обоймами, образованными гиперболическими приводными валками /, установлена обойма, образованна  двум  холостыми валками, один из которых опорный вогнутый 2, а другой нажимной выпуклый S. Угол наклона холостых валков может быть равным или меньшим угла наклона приводных валков . Правка труб (прутков) происходит по всей длине, .включа  концы. Одновременно сBetween the clips formed by the hyperbolic drive rollers /, a clip is formed that is formed by two single rollers, one of which is a supporting concave 2, and the other pressing convex S. The angle of inclination of the single rollers may be equal to or less than the angle of inclination of the drive rollers. Editing of pipes (bars) occurs along the entire length, including ends. At the same time with

правкой устран етс  овальность труб. Так как труба (пруток) прорабатываетс  знакопеременным упругопластическим изгибом за счет смещени  средней пары валков и деформировани  в калибре, образованном валками средней пары, правка ведетс  с повышенной точностью.straightening eliminates pipe ovality. Since the pipe (rod) is worked out by alternating elastoplastic bending due to the displacement of the middle pair of rolls and the deformation in the caliber formed by the rolls of the middle pair, the editing is carried out with increased accuracy.

Разность окружных скоростей в двухвалковом калибре,  вл юща с  следствием разности диаметров валков, обеспечивает полировку поверхности выправл емых труб (прутков ).The difference in circumferential velocities in the two-roll caliber, which is a consequence of the difference in the diameters of the rolls, provides for the polishing of the surface of the straightened pipes (rods).

Предмет изобретени Subject invention

Устройство дл  Правки труб и прутков, содержащее две валковых обоймы с косо расположенными приводными валками и установленную между ними сМещенную относительно оси правки двухвалковую изгибающую обойму, отличающеес  тем, что, с целью повышени  точности правки по всей длине трубы или прутка, Опорный валок изгибающей обоймы выполнен вогнутым, а нажимной - выпуклым.A device for straightening pipes and rods, containing two roller holders with obliquely arranged drive rolls and a two-roll bending ferrule placed relative to the straightening axis, characterized in that, in order to improve the accuracy of the straightening along the entire length of the pipe or bar, the bending ferrule support roll is made concave, and push - convex.
