    The invention relates to mechanical engineering and can be used when cutting large-sized pipes.
    The aim of the invention is to increase productivity, cut quality and ease of operation by deflecting the cut end of the workpiece from the cutting tool by means of a deflection roller and trapping the cut end of the workpiece with an L-shaped swivel lever.
    FIG. 1 shows the device) b | tion view; in fig. 2 - deflecting device; in fig. 3 - deflection roller, general view; FIG. 4 is the same, top view; in fig. 5 shows the process of deflecting and separating the cut end of a tubular part; in fig. 6 shows the process of trapping the cut end of the workpiece; in fig. 7 - cutting device, end view of the pipe.
    The tubular part T is cut, having the possibility of rotation from the axis X-X, located on the side drive rollers 1 and fixed by an abutment in front of the cutting tool 2, located in the DR plane (FIG. 2), perpendicular to the axis X-X running in the wall 6 of the pipe being cut, an annular groove 3, bounding the pipe section 4, located on rollers 1, and the pipe cut part 5, which is separated by the deflecting roller B, is mounted, which can be rotated relative to the YY axis parallel to GCH X-X, and moved to radial ohm ON direction to axis X-X.
    The tilting roller 1 is mounted slightly above the cutting tool 2 at a right angle to the cutting plane indicated in FIG. 4-6 line Z
    The deflecting roller is mounted on the base 7 and has the shape of a circular wedge 8 (Fig. 3-5), having in cross section the shape of an isosceles trapezoid, bounded by a surface 9 1 on the sides with oblique poverknost, turning into a crush-shaped support surface 10 and terminated by pivots 11, rotating in bearings mounted in the side column t2 of the fork 13, which is I-shaped and mounted on the rod 14, passing through the cover 15 of the jack 16. Axial clearances J1, J2 are provided between each cylindrical surface 10 and the end of the rack 12
    Often, the self-centering deflecting roller E in the groove 3 and the possibility of axial movement of the roller E along the axis Y-Y to the cut end of the pipe 5 are self-centered.
    The sum of the axial clearances j1 and j2 is less than or equal to the width from the base of the ring wedge 8 minus the width a of the wedge, which allows the wedge part of the roller E to enter the annular groove cut by the cutter.
    five
    The device also contains a horizontally mounted (parallel to axis X-X) lever 17 mounted for rotation on a rod 18 fixed on a height-adjustable bracket (not shown)
    Emery can also be used as a cutting tool.
    0 a disk 19 (FIG. 7) mounted on a lever 20, pivotally connected to a shaft 21, fastened to a base 22, on which a stop 23 is mounted, limiting the stroke of the lever 20.
    5 The device operates as follows.
    The jack 16 and deflector 5 "th roller E are installed so that the radial direction of the RB is shifted to the corner
    (Fig. 2) with respect to the radial direction of movement of the Cutting tool 2 through the pipe wall T,
    The pipe T, fixed in the axial direction, is rotated in the direction indicated by the arrow R (Fig. 1 and 2),
    At the beginning of the cutting operation, the deflection roller B is set so that the radial direction of its movement coincides with the Z-Z line of the middle cutting plane, perpendicular to the X-X axis and passing around the middle of the annular groove 3 (, 4), and the cylindrical part the deflecting roller from the very beginning of the cutting operation rests on the wall of the tubular piece T and rolls about it.
    As soon as tool 2 begins to cut through the groove, jack 16 begins to move the deflecting roller E in the direction of groove 3 along the radial direction DE crossing

    )
    axis X-Xj, the axis of rotation Y-Y remaining parallel to axis X-X. When the annular wedge 8 enters directly into the groove 3, it may be that the median transverse plane of this wedge does not quite coincide with
    the middle transverse plane of the groove 3. In this case, the two inclined side surfaces 9 non-simultaneously come into contact with the corresponding outer edges of the groove 3 (FIG. 4). These contacts occur sequentially due to the presence of axial gaps j between the cylindrical surfaces 10 and the posts 12 of the fork 13, which provide automatic self-centering of the roller E in the groove 3. Automatic self-centering is also ensured by the fact that the sum of the gaps j is smaller than the width minus the width a of the cylindrical part . Thus, the roller E enters the groove 3 cut by the cutting tool 2.
    Under the action of the jack 16, the force of which is directed along the axis Z-Z, the annular wedge 8 enters the groove 3 (Fig. 4). At the beginning of the cutting operation, the cylindrical part rolls along the bottom of the groove 3. Then, as the cutting depth increases, the side on the clone surfaces 9 begin to abut against the edges of the groove being cut. At the end of the cutting operation, at the moment of separation of the cut Koits from section D of the tubular part, the ring wedge 8 continues its movement towards the axis X-X (Fig. 5) until its cylindrical part 10 rests against the wall of section 4 of the tubular part, thus stopping the further advancement of the roller E in the groove 3.
    At the same time, while the roller E finishes its entry into the groove 3, its lateral surface abuts against the edge of the tubular section 4, blocked from the axial longitudinal movement -. This forces the roller E and the wedge 8 to axial movement on the trunnions 11 along the Y-Y axis, with the result that the inclined lateral surface 9 deflects the cut end in the direction indicated by the arrow F (Fig. 5). This becomes possible due to the presence of the axial clearances J1, J2 .. In the cutting operation (Fig. 5), the axial clearances become unequal: j1 on the side of part 4 is much larger than j2 on the side of the cut end 5. The cut end is initially abutted tangentially into the cylindrical surface 10, then flips on the outer edge 9 of this cylindrical part, as shown by the stele G and fig. 5, after it is deflected from the cutting tool 2 by means of a roller E F in a direction approximately parallel to the axis X-X of the tubular part T. The cut end remains on the lever 17, which prevents it from falling. The lever 17 rotates around the gatok 18 with the aid of known means (not shown) and moves the cut-off end to the side.
    After stopping the rotation of the tube T, or just before stopping, the jack 16 is actuated and the deflection roller E is returned to its original position for the next cutting operation.
    The deflection roller E destroys the thin bottom of the groove 3 at the end of the cutting operation before the cutting tool 2 does.
    As a cutting tool, an emery disk 19 (FIG. 7) can be used, driven in motion and mounted on a lever 20 pivotally connected to a shaft 21 rigidly connected to a frame. The deflection roller E is installed below the emery disc 19 and enters the annular groove cut by this disc, the roller is located lower and as close as possible to the emery disc 19. In order to avoid dropping the disc 19 working under the force of gravity on the roller E at the end of the cutting operation a stop 23 is provided that is mounted on a frame and restricts the movement of the lever 20. In addition, this device, as well as the described construction, contains a restraint and retractor 17.
    The use of the proposed device will improve the performance of the sections and ensure convenience of work, especially when cutting pipes of large diameter.
