    A cold metal ring is greatly expanded in radial diameter and simultaneously contoured to a desired cross-sectional shape by successively rolling the ring between selected pairs of roll dies. If necessary, the ring may be annealed between successive cold rolling operations sufficiently to permit movement of ring material without fracturing the ring. Thereafter, the rolled ring may be expanded to a precise radial diameter utilizing a precision expander. Dimensional and contour control of the ring is comparable to that attainable by machining.

    The invention relates to the technology of manufacturing metal ring blanks of various cross-sectional shapes and can be used in the manufacture of parts for gas turbine engines with cold rolling and subsequent calibration.
    The aim of the invention is to increase productivity and utilization of the material of the workpiece.
    FIG. Figure 1 shows the metal initial billet of the ring in Fig. 2 — an annular intermediate billet obtained by rolling a metal initial billet of the ring; FIG. 3 shows an annular clamp for rolling, obtained from an annular intermediate billet by connecting its ends j in FIG. 4 - profiling rolls, cross section; in fig. 5 - the same fragment; in fig. 6 - ring, cross section, at the initial transition of rolling; in fig. 7 - the same, at the intermediate transition of rolling; in fig. 8 - the same, on the final transition of rolling.
    For rolling, a blank is used ((} "d. 3), the weight of which must be equal to the weight of the finished ring, and the diameter must be significantly smaller (usually half) than the required roBofo th ring. The connection of the ends of the ring blank (Fig. 2) in the manufacture of the original billet (Fig. 3) can be carried out by any known method.
    The blank (phi1. 3) is rolled out over several transitions by pairs of profiling rolls forming a closed caliber. At the first transitions, the reel is rolled out with its material displaced predominantly in the axial direction in order to achieve the maximum axial redistribution of the material with a minimum increase in diameter. At the last transitions, the workpiece is rolled out with its material shifted predominantly in the tangential direction in order to achieve the exact shape of the ring section with increasing diameter. The rolls may be lubricated with greases or molybdenum disulfide, which is especially necessary for the axial distribution of the ring material.

    The number of pairs of rolls required depends on the degree of reduction and the ability of the material of the workpiece to strain hardening. The profiling rollers 1 and 2 should form a closed caliber (Fig. 4 and 5), completely covering the profile of the rolled ring 3 and having planes 4 and 5. A gap is provided between adjacent roll surfaces 6-9. The rolls of each pair are made with shoulders 10 and 11, and one of the rolls can be made with a sharp protrusion 12 (Fig. 5).
    Between roll transitions, it is advisable to anneal the ring; nickel or cobalt rings are recommended to be annealed after a 20% reduction in thickness. In order to impart to the billet a ring of precise diametral dimensions, calibration is carried out on the mandrel after rolling by distribution.
    Example. Rings of nickel and cobalt alloys (Inconel 718 and 625) with a diameter of 610 mm, a width of 12.7 mm and a weight of 9.07 kg are rolled by the proposed method to a diameter of 1270 mm and a width of 25.4 mm in three transitions (30 seven passes with a force varying from 13,500 to 18,300 kg.

    1. A method of manufacturing billet rings, in which a billet is made, the diameter of which is less than the dieter of the finished ring, and the mass is equal to the assembled ring, is deformed by rolling in several transitions with pairs of profiling rolls, and then finally deformed, characterized in that productivity and coefficient of use of the material of the workpiece, on the initial and final transitions of the pre-deformation, the workpiece is rolled out with a predominant displacement of its material but in axial and tangential directions.
    1, the difference is that the end2. The method according to claim 5, and so that the deformation of the ring blank is carried out by dispensing on a calibrating mandrel.
