    A cast-iron pipe having an end socket is rotated about its axis by a driven first roller applied against the outside of the socket and a driven second roller applied against the inside of the socket and pressing the latter against the first roller. The rollers can be rotated at differing speeds, and as the socket revolves they rub off or crush burrs or other irregularities on the outside and inside of the socket. A cutting tool on a pivoted lever arm is applied by motor power to an outer face of an end flange of the rotating socket to trim burrs therefrom. The second roller supported on an articulated arrangement can be swung into and out of the socket by operation of a first hydraulic jack. Another hydraulic jack arrangement presses the second roller against the inside of the socket and increases the pressure suddenly when the roller encounters a large irregularity and decreases the pressure to normal when that irregularity has passed the roller.

FIG. 1 shows a part of the casting in a chill mold with a rod; in fig. 2, 3, - the main types of foundry flare socket; in fig. five . device, general view; in fig. 6 is a section A-A in FIG. 5 in FIG. 7 diagram of the hydraulic actuator. A device; in fig. 8 - device, inoperative position; in fig. 9 rollers in the process of running the bell. The invention is used for the clean processing of a cast-iron pipe 1 having a socket 2, obtained by centrifugal casting into a chill mold 3. A rubbed-out socket allows to obtain a flat end portion 5 of the socket, an inlet flange 6, an annular groove 7 and a chamber 8 at the bottom of the socket, which connects with the inner cylindrical wall of the pipe body in the middle of the radial shoulder 10. Kokil 3 forms the outer surface 11 of the socket 2, Possible defects (Fig. 2-k) can occur when the annular protrusion of the rod breaks, forming large clusters 12 to a few millimeters of cast iron. The elongated protrusions 13 become the result of surface cracks. When the metal mold is worn, the faces of 1C may form on the outer surface of the socket, burrs. 15 on the peripheral part 16 of the chill mold, which is a consequence of the HennofHogo fit of the rod to the chill mold. If the rod is poorly insulated with an anti-stick coating, a rough inner wall 17 may appear. The casting defects described are eliminated by means of a device containing a frame 18, a support device 19, two chipping rollers 20 and 21 and a machining tool 22. The support device includes racks 23 each of which is fixed by its middle two. corner arm 2, carrying on the upper fork end idle support roller 25 of the pipe body. The jack 2b is installed between the frame and the lower end of each lever 2. The rollers 25 are located at the same level. A rack 23 adjacent to the bell 2 has a guide roller 27 of the output shaft 28 of the gear motor 29 attached to this rack. The shaft 28 with an axis parallel to the axis of rotation of the workpiece extends from the side of the socket 2 and carries an outer roller 20 at this end, the profile of which corresponds to the profile of the outer surface of the socket. The profile of the inner roller 21 corresponds to the annular groove 7 of the socket 2. This roller 21, which has a diameter smaller than the diameter of the outer roller 20, is fixed to the front end of the shaft 30 mounted in the hollow spindle 31 and connected to the gear motor 32. The spindle 31 rests on the hinge device 33 formed by a connecting rod 3, double jacks 35 and a simple jack 36. The connecting rod Z is pivotally connected by its upper fork forks to the front end of spindle 31, and its lower end to the bed 18. The double jack 35 is hinged on one side on the frame 18, and on the other, on the embossing 37. It has an inner body 38 in which the piston 39 slides to form the docking jack 40. The piston rod 39 of this jack extends upwardly, hollow and forms the housing of the jack 41 for taring. The rod 42 of this jack is pivotally fixed with a fork with a baffle 37. The machining tool 22 is fixed on the upper end of the lever 43, the middle of which is pivotally fixed on the stand 23. And the lower end is pivotally connected to the connecting rod -f, which is pivotally fixed on the eccentric 5 rigidly connected to the secondary shaft 6 of the gear motor 1, the engine 7 has two speeds and two directions of rotation. The power supply of the jack 40 includes pipes 48 and iS, extending from two sides of the housing 38, and a spool valve for connecting the pipelines 48 and 49 for the working medium in the direction of the arrow 50 by the pump 51 and the tank rum 52. The power of the jack 1 for calibration is carried out Two pipes 53 and 5, a spool two-position device 55, a pump 5b and a tank 57. The pump 5 is set to the required pressure (about 100 bar) by a calibrated valve 58 installed on the branch pipe 59 connecting the pipeline water 53 and 5 and connected on the one hand between the pump and the switchgear 55, and on the other, between the last and check valve 60, which goes to the cutter 57. At the outlet of the switchgear 55 in the pipeline 53 a check valve 61 is installed, controlled pressure pipeline 5. To the terminals of the valve 61 is connected in branch a special valve b2. Receiver 63 with a deforming membrane, pressured to a pressure multiple to the pressure supplied by pump 5b, for example, a three-fold pressure switch retrofitted to pressure slightly lower than pressure 63, but significantly higher than the pressure supplied by pump 56, connected to points of the pipe 53 located between the system 61-62 and the jack 1. The switch 64 is arranged to overturn its time when it is supplied with electric current by the IM as soon as the pressure in the pipe 53 exceeds a predetermined pressure That is, in order to give a signal Special valve b2, mounted on the branch of the check valve 61, on the branch pipe 65 has a bore hole 66, open at both ends of the ports b7 and 68 on the - branch pipe b5, as well as channel b9, branching with respect to the thawed hole 66. Channel 69 is provided with a diaphragm 70, limiting to a small amount the flow rate of the working medium that passes through it. In the bore hole 66, the piston 71 slides, elongated by a needle-like | m valve 72. capable of closing the hole 67 closest to the distributor device 55. The spring 73 is compressed between the piston 71 and the bottom of the bore hole 66 from the side of the hole b7. The spring tends to return the piston 71 to the position of the stop against the other end of the bore hole 66, a position in which the coupling channel 69 communicates with the branch pipe 65 through the holes b7 and 68. The spring 73 is set to a corresponding small force, taking into account the cross section-piston 71 at a pressure well below pump pressure 5b. In the non-working position (Fig. 8), the three jacks 36, AO, and k retraction are inward, and the spindle 31, the connecting rod 3 and the double jack 35 are in an inclined position. The inner roller 21 is raised and the tool is retracted, which allows the part to be cleaned to be mounted on the side support rollers 20. The device operates as follows. The working medium is fed to the inclined jack Zb under pressure from the bottom. The inner roller 21 enters the bell 2. The power of the jack stops slightly before the end of its run, when the roller 21 is plumb-up into the inner annular groove 7 of the socket. The connecting rod 3 is upright at the same time. The docking jack 40 is powered by a pressurized medium from the bottom. Its piston 39 remains in its upper position during the entire stroke of the machine, as its supply pressure is sufficient to resist the reactions of piston 42. The spindle 31 swings around its hinge on the connecting rod 34, and the inner roller 21 approaches the flared ring groove 7 to be machined. When the docking jack 40 reaches the end of the run, the inner roller 21 is close to the annular groove 7, but not yet in contact with it, while the small jack k for taring is still drawn in. The drive distributor is in the position shown in FIG. 7 serves a high-flow working medium into the inner chamber of the jack W through valve B1. The roller 21 touches the inner annular groove 7 of the socket, and its axis becomes parallel to the axis of the pipe. The power of the PLC jack is resumed from the bottom side to ensure, by means of the axial force exerted on the roller 21, a shearing action which permits the outer edges of the socket to be machined. Three groups of gear motors 29, 32 and k7 are running. As a result, the pipe is rotated in the direction of the arrow (Fig. 6) by two rollers 20 and 21, between which it compresses with the socket 2, with roller 20 rotating in the direction of the arrow. The speed of rotation of the rollers is in 1 68 limits of 15 rpm. A larger diameter roller 20 plays the role of a support or anvil, crushing encountered irregularities, while a small diameter roller 21 plays the role of a grinding tool. The cutting tool 22, in turn, approaches at rapid feed, then touches the peripheral input edge of the socket 2. During several turns of the pipe around its axis, the socket 2 is compressed radially between the two rollers 20 and 21 under the action of the joining force jO and the calibration k jacks and axially cutting between two rollers with an angle jack Zb, which presses (eolik 21 to the transverse surfaces of the inner surface of the socket). The angle jack 36 thus plays the role of a prop, and the reaction It is provided with a roller 20. The impact of the rollers 20 and 21 causes the crushing of small roughnesses and the grinding of the inner and outer profile of the socket.
