    The invention relates to the processing of metals by pressure and can be used when rolling annular and helical grooves on the walls of parts having the form of rotation bodies.
    The aim of the invention is to improve the quality and expansion of technological capabilities by making grooves on thin-walled hollow parts.
    Figure 1 shows a pattern for rolling grooves; figure 2 - a set of four
    rolling rollers with two working edges, cut; Fig. 3 is a scheme for rolling a helical groove on a cylindrical hollow part; figure 4 is the same on the conical hollow part; Fig. 5 is a diagram of a device for rolling grooves;
    The method is carried out as follows.
    The roll roller 1 is installed with the possibility of free rotation on the axis XT, perpendicular to the plane of the drawing. The axis Hch is moved parallel to itself in such a way that its point of intersection with the perpendicular plane performs a cyclical movement along an elongated closed curve 2 in the direction of rotation of the part indicated by arrows F1 and F2. Curve 2 is close in shape to an oval or ellipse. Its largest BC diagonal intersects at a right angle at point M a short diagonal AU, the continuation of which intersects deformation zone 3 and the X-axis of part 4, and the diagonal AU length is smaller than the diameter of the working edge 5 of the knurling roller 1. Curve 6, the envelope of the working edge of the working edge roller 1 intersects with part 4. During processing, the knurling roller rotates in the direction of the arrow Pz, and its working edge 5 forms a deformation zone 3 on the part, which moves along the wall of the part.
    Moving the knurling roller in this way reduces the angle of inclination of the working edge at the initial moment of its interaction with the part and significantly improves the deformation conditions. In most cases it is advantageous to use several rolling rollers placed on different sides of the part. At the same time, the axis of each rolling roller is moved along an elongated closed curve along which the axis of the other roller does not pass, and the working edges of the rollers are located both in one plane and in several parallel planes.
    To make the helical grooves, the roller or part is moved in the axial direction, and the speed of the axial movement is coordinated with the speed of rotation of the part. When using a set of knurling rollers their working edges
    must be offset one relative
    R
    another by the value of y, where P is the pitch of the screw profile; Z - the number of rollers in the kit.
    In some cases it is advisable to use more complex knurling rollers with several working edges (figure 2). Each of the rollers 7-10 contains two
    working edges. In this case, the radii of the edges A- | -A4 are different, i.e. Ri R2 Ra R4. The working edges 81-84 are the same size and serve to align and
    5 reinforcement grooves, pre-formed edges.
    To improve the quality when making the helical grooves, the plane of the working edge of the roller 11 is tilted at an angle a
    0 axis details 12 (fig.Z). The angle of the roller, as a rule, is equal to the angle of elevation of the helix 13.
    When rolling screw grooves on parts having a conical shape (figure 4),
    5, during the deformation process, they change the distance between the path of the working edge of the roller 14 and the part 15, while simultaneously controlling the depth of the deformation zone.
    Improving the accuracy and quality of the surface is also achieved by the fact that the groove formed by the knurling roller is additionally treated with at least one rolling roller freely mounted on a fixed axis.
    5 The method is carried out as follows.
    When rolling an external thread on a steel pipe with a diameter of 1/2 inch and a wall thickness of 6 mm, the pipe is rotated at a speed of 9 rpm and radial movement relative to the rollers at a speed of 38.1 mm / min. Four rollers with a diameter of 61 mm, each of which has one working edge, are located on axes located on different sides of the workpiece. In the rolling process, the axes of the three knurling rollers are moved in such a way that their points of intersection with the perpendicular planes make a cyclical movement along elongated closed curves. The number of cycles is 2000-3000. The fourth roller is rolling; it is rotatably mounted on a fixed axis. Maximum 5 for the penetration depth of the working edges of the rollers is, mm: for the first roller 0.4; for the second, 0.8; for the third 1.2; for the fourth 1.2. The thread made in this way has high accuracy
    0 and good surface quality. At the same time, in the area where the thread is made, the internal diameter of the pipe remains unchanged.
    A device for making grooves by plastic deformation comprises
    5 knurling rollers 16 freely mounted on axles Xs in movable roller bearing bodies 17, support ring 18 rotatably disposed in housing 19, movement mechanisms and
    adjusting the radial position of the roller holders and the mechanisms for setting the angles of inclination of the rollers (not shown). The device also includes a fastening mechanism and a drive for rotating the part 20 (not shown).
    The adjustment mechanism of the radial position of the roller holder is made in the form of an earring 21, pivotally connected by means of axles 22 and 23 with a support ring and roller holder. The mechanism for moving the roller holder is made in the form of an eccentric axis 24 with a drive (not shown), which is installed in the roller holder 17c with the possibility of rotation. The role-holder is made in the form of a triangle, on the vertices of which the axis Xs of the roller 16 is freely installed, the axis 22 of the earrings 21 and the eccentric axis 24, all three axes being mutually parallel,
    To perform helical grooves on both cylindrical and non-cylindrical parts, the device is equipped with a mechanism for axial movement of the part (not shown), which is associated with a drive for rotating the part, and a mechanism for adjusting the radial position of the roller holder. Along with movable roller holders 17, in each of which the knurled roller 16c is freely mounted with working edges, the device can be equipped with fixed roller holders in which rolling roller bars are freely located on fixed axles
    for calibrating grooves formed by knurling rollers.
    The device works as follows.
    The workpiece 20 is mounted in the mechanism of fastening the part and is driven into rotation. The eccentric axis 24 is said to rotate around Cs clockwise. At the same time, the axis of the knurling roller Xs starts cyclically moving parallel to itself along an elongated closed curve 25 in the direction of an hour hand. The working edge of the roller forms a deformation zone 26 on the part, which moves along the wall of the part, and the roller itself rotates in the direction of arrow F4.
    When rolling helical grooves, the part is moved in the axial direction synchronously with its rotation, and the working edges of the rollers are set at an angle to the axis of the part, equal to the elevation angle of the helical groove. The change in the distance between the rollers and the part is made by rotating the ring 18.
    The present invention allows to improve the conditions for deformation of the part, to improve the quality of the surface of the grooves, and also to expand the technological capabilities by making the grooves on the thin-walled hollow parts.
