    And is driven into rotation by a gear motor 9.
    The tool 6 is mounted for movement within the sleeve 10 and is fixed to the end of the nut 11, capable of moving in the sleeve 10. The screw 12 is axially mounted in the nut 11 and is driven into rotation by a coupling connected to the output shaft of the engine 13. The nut is cleared with a key 14, providing her one degree of freedom.
    The design of the device provides at least one clamping roller 15 dd holding parts 4 on the carrier rollers 2 and 3. The roller 15 is mounted on the bracket 16, which can be rotated on the base 17 around the horizontal axis 18. The upper part of the bracket 16 is rigidly connected tubular caliper, which is attached to the gear motor 19,
    The double action jack 20 is articulated on the axis 21, parallel to the axis 18 and connected to the base 17, and the end of the rod-hinge- is fixed on the lever 22 by the axis 23.
    The roller 15 is set in such a way that the radial plane P passing through the axis X-X of part 4 and the dry roller 2 is located at an angle of C from the radial plane 7 passing through the axis of the roller 15.
    If the part is made with a socket 5, then from movement in the axial direction it is held by rollers 24 and 25, and roller 25 has a central peripheral groove in which the flange of the pipe is installed.
    The groove section is trapezoidal with an angle. With a significantly larger angle of keystone flange (g,
    which ensures that the backlash-free axial retention of the pipe 4 during trimming is guaranteed, since the flange is set with its ribs on the sides 26 of the groove, and not on its bottom.
    The device works as follows.
    The tubular part 4 is supported with rollers 24 on one side and rollers 2 and 3 on the other hand, actuates jack 20 and presses roller 4 on roller 4 and rollers 2 and 3. Instrument 6 is oriented in the angular position, include gearmotors 9 and 19 for driving the respective rollers 2 and 15, and therefore also parts 4, At the same time, start the engine 13, which is equipped with 10

    They are not content to move the carrier roller 3 without changing the relative positions of the carrier roller 2 and the pressure roller 15. The idler roller 3 is moved by any appropriate means, such as a screw screw, either radially up the tube axis X-X or vertically up or inclined in the direction intermediate between vertical and radial directions.
    In order to receive a pipe with a diameter smaller than pipe 4, it would be possible to leave rollers 2 and 3 fixed and only change the position of pressure roller 15, and consequently, change the angle of displacement between roller 15 and the radial plane P

    tool 6.
    In the process of trimming, the internal pressure roller 15 exerts a force on the inner wall of the pipe T opposite to that which the tool 6 applies to the outer wall, and therefore allows the pipe being cut to be pressed against the cutting edge of the tool 6 better.

    and the radial plane 1 of the carrier roller 2 and the cutting tool 6 (FIG. 1). also allows the tubular part 4 to be pressed against the two outer bearing rollers 2 and 3 against the centripetal. the radial force of the cutting tool 6, which leads to loss of contact of the pipe 4 with its bearing rollers 2 and 3. The combination of three rollers 2, 3 and 15 with angular displacement provides a stable balance of the pipe 4 on the bearing rollers 2 and 3 during cutting.
    When trimming is complete, the cut end is removed, the engines 9, 19 and 13 are turned off and the jack is turned off so that roller 15 is pulled out of pipe 4 by folding the bracket 16 around axis 18,
    The combination of three bearing 2 and 3 and pressure rollers 15 is suitable for pipes of 4 different diameters, moving only one of the rollers. In the case of installation on a cutting machine of a cut pipe with a diameter smaller than the diameter of pipe 4 (Figures 1-4), , in order to allow the tool 6 to cut the pipe, work under optimal cutting conditions45
    18 under the action of the jack 20 roller 1 occupies a new supporting position on the inner wall of the pipe.
    The device shown in Fig. 8 differs from the previous ones in that it contains two drive rollers 27 and are paired each with one cutting tool 29 and 30, and these elements are arranged symmetrically relative to the axis X-X of the parts 4 and relative to the vertical plane. R, with the holding axis HTH. In addition, the device is equipped with two clamping rollers 31 and 32 inside part 4, which are displaced to the axial vertical plane P of the part T with respect to the respective carrier rollers 27 and 28. Each of these displacements corresponds to y-o. ..
    The tool 29 is radially displaced on the drill pipe 4 to the depth of the passage j with respect to the tool 30. In this arrangement, the cutting time is halved. This device can be used for transverse cutting of thick tubular walls.

    In the following embodiment (Figs. 9 and 10), the device comprises one fixed lower roller, the axis of which is in the axial vertical plane P, the Non-slip roller 33 is capable of being driven by a gearmotor (not shown) and paired at least with one cutting tool. Two outer side rollers 34 and 35 are located under part 4 symmetrically relative to the axial vertex
    they are not content to move the carrier roller 3 without changing the relative positions of the carrier roller 2 and the pressure roller 15. The idler roller 3 is moved by any appropriate means, for example a screw jack, either radially to the X-X axis of the pipe, either vertically upwards or inclined in a direction intermediate between the vertical and radial directions.
    In order to receive a pipe with a diameter smaller than pipe 4, rollers 2 and 3 could be left stationary and only the position of pressure roller 15 could be changed, and consequently, the offset angle between roller 15 and radial plane P could be changed
