    专利说明:

    The invention relates to the processing of metals pressure and can be used in the manufacture of ring products. An automatic multi-ring rolling mill is known, containing four internal idle pressure rollers installed in sliding carriages arranged in pairs and diametrically opposite to the external drive roller jioKpyr. The feeds of the inner rolls on the mill are driven by a system of leverage and cams. The disadvantage of this mill is the low accuracy of manufacturing of the products, due to the low rigidity of the internal rolls feeding system. The closest to the proposed; is a ring rolling mill, a housing, in which a rolling table is installed with four inner rolls that can be axially moved, the additional support is located at the rolling position, outer drive roll, two end rolls, one of which is driven and mounted with possibility of movement in the axial direction, the other is fixed 2. The disadvantage of this camp lies in the fact that a large number of movements of significant masses is carried out to implement the work cycle of the mill, which requires additional time for accelerating and decelerating the corresponding mill components and parts, which leads to a decrease in productivity. In addition, constructive installation of the inner rolls does not provide high precision manufacturing of the rings. The purpose of the invention is to increase productivity by reducing the takt time and improving the accuracy of manufacturing the products. This goal is achieved by the fact that a ring-rolling mill, comprising a housing in which a rolling table with four inner rolls having axial movement, is mounted, additionally to a support, located at the rolling position, an outer drive roller, two rollers, one of which driven and installed with the possibility of movement in the axial direction, the other is permanently installed, as well as the measuring device, equipped with a sled mounted in the housing with the possibility of About the movement with the help of a power cylinder, the outer swath is fixed on the sled, the rolling table is made with a swivel, the inner rolls are installed in the turntable with the possibility of fixation at several levels below and above the table surface. In this case, the slides are associated with a monitoring device. Such a constructive implementation ensures the movement of the minimum mass and reliable fastening of the inner rolls. The rolling table remains stationary during rolling, due to which it is convenient to replace the processed products, as well as to lubricate and cool the internal rolls that are not at the rolling positions. FIG. 1 shows a ring rolling mill with several internal rolls, a vertical section; in fig. 2 — in the upper half — a ring-rolling mill, top view, and in the rizhnii — section A-A in FIG. 1. On a stationary ring-shaped case 1 cTatia, a plate 2 of the table is fixedly mounted, on which can be found known devices for the automatic feeding and removal of workpieces. Rotating rolling protrudes into the circular opening 3 of the table plate 2. Table 4, the carrier system 5 of which is mounted in the housing 1 of the ring rolling mill in bearings 6 with the possibility of rotation through the gear rim 7 and the drive (not shown) in the direction opposite to the direction of rotation clockwise in succession in steps of 90. The diameter of the rolling table 4 is made as small as possible so as to reduce the duration of the work cycles to reduce the inertial mass and to reduce the transport paths of the treated loops. On the fastening system 5, the housings 8 and 9 of the lower bearings of the inner rolls 10c are placed with the possibility of movement in the axial direction, in which the rollers 10a - lOdI are rotatably attached and mutually replaceable. The rolls 10 through the holes 11 of the rolling table 4 protrude above its surface. The guide curve (not shown), as well as the power cylinders 12 and 13, ensure that, when the rolling table 4 rotates, the housings 8 and 9 of the bearings 10 rolls 10 a-lOd of movement in the following order. The roll in the unloading position and for this reason in the lowest position, namely the roll of 10 s, which is in such a position when its upper end is under the level of the rolling table 4, when the rolling table 4 rotates, it first gets into the cooling position - the position taken by the roller lOd. Here, on the ring rolling mill casing, a power cylinder 12 with a pusher is fastened, which allows in this position, the roll bearing housing 8 to raise the curvature of the mandrel by means of a guide curve and thereby move the mandrel to the cooling position, cleaning, lubricating or even replacements. Then, the roller bearing c-8 is again lowered along the guide curve and during the subsequent rotation of the rolling table 4 is fed to the loading position, namely to the position of the roller 10a. In this position, the ring billet 14 is fed to the rolling table 4 so that it is exactly over the roll 10a lowered. At the beginning of the next rotation cycle of the rolling table, the roll 10a is fed upwardly so that it guides the ring blank 14 securely and reliably. With the ring blank 14, the corresponding roll at the same time as the rolling table 4 is fed to the rolling position. The other power cylinder 13 is designed so that the roller bearing housing 9, which is at the bottom, namely the roller lOb, lifts our guide curve and moves it to the extreme upper position, in which the free end of the corresponding roller lOb will rest the upper housing of the roll bearing 15, which is in the upper position. After the end of the rolling process, the roll during the subsequent movement along the guide curve descends to a position in which the subsequent ring 16 moves the finished ring 16 to the unloading position — the position of the roll Yus. When approaching the unloading position, the roll again lowers from to the lowest position and the finished ring is dropped from the rolling table. The roll bearing housing 15 is mounted at a certain distance above the rolling table 4 on a support arm 17 rigidly joined to the ring-rolling mill housing 17. The outer roller 18 is located on the main shaft 19 and is removable, the latter is mounted in the lower bearing housing 20 and in the upper housing 21 bearings with the possibility of using them by means of an actuator 22. The lower bearing housing 20 and the actuator 22 are rigidly located in the slide 23, with the bearing housing 20 and the leading shaft 19 passing through coaxial holes 24 and rotating iZS Foot section 4 and 5 attached sistegF laziness .Tochno also on skids 23 are secured two arms 26, on which the replacement of the outer roller 18 is housed detachable crosspiece 27, in a cat swarm housing 21 is secured the outer shaft bearing. The slides can be moved along guide rods 2 & in the radial direction to the outer roll 18 and to the inner roll lOb in the rolling position. These movements are made by means of a ram cylinder, the casing 29 of which is mounted on the slide 23, and the rod 30 is hinged to the casing 1 of the ring-rolling mill. The movement of the slide 23 during the rolling process is carried out by means of a measuring device. The measuring unit of this device is the control roller 31, which is spread out on the pusher 32, allowing the control roller 31 to move with respect to the sled 23 in the radial direction to the roller OO. The control roller 31 is connected to a distance indicator (not shown) and under the action of the power cylinder 33 can be pressed against the outer surface of the ring 16 in the rolling position. The support rollers 35 attached to the centering pushers 34 can feed into the slide approximately radially to the ring 16 in the rolling position. Their asymmetrical position, on the one hand, provides the greatest rigidity of the entire system, and on the other hand, unimpeded transportation of both the workpieces of the rings and the x rings during subsequent rolling of the rolling table 4. By means of an automatically acting drive of the centering pushers 34, using a measuring device, it is ensured that, on the one hand, the ring 16 during the rolling process remains in a centered position with respect to the plane, The axles of the outer roll 18 and the control roller 31, on the other hand, are not deformed by centering forces. The support arm 17, which is rigidly mounted on the housing 1 of the ring-rolling mill, in addition to the roller bearing housing 15, is provided with a power cylinder 36, which, when switched on, releases the axis in the rolling position — in the shown position of the roller 10b — from its upper bearing and provides due to this downward movement of the corresponding housing 9 of the roll bearing. On the support arm 17, bearing housings 37 and 38 are mounted for rotating cone-shaped axial rolls 39 and 40. The lower end roll 40 is fixed stationary, while the bearing housing 37 of the upper end roll 39 is mounted on rails, which allow movement in the axial direction to the rolled ring, and ensures the creation of the necessary rolling effort on the end surfaces of the rings. The upper end roll 39 is rotated by a drive 41, which is automatically. is adjusted for the corresponding ring speed.
    Compared with the known base object, the proposed ring-rolling mill provides increased productivity by reducing tact time and increasing the accuracy of fabrication of products.
