    water is installed in the bed 2. In the intermediate element there is a horizontal channel with approximately square cross-section in which the end 7 of the console 8 is installed, the channel cross-section corresponding to the cross-section of the end 7 of the console 8, the hydraulic actuator 9, the piston 10 is mounted in the upper part of the intermediate element 6 which, by means of a connecting element 11, is connected to the end of a console J, whereby the console moves 2 TCW along its longitudinal axis, but e can rotate. At the front end of the console 8 is installed a vertical power cylinder 12, the rod of which 13 is directed downwards, bears on itself the housing 14 rotatable around its longitudinal axis.
    The housing 14 is equipped with an extension rod 15 installed perpendicularly to the axis of the stem 13, at the end of which, with the possibility of adjusting, an additional housing is mounted around its longitudinal axis with a rotatable axle parallel to the base 1 of the supporting cup 16, in which the installation a sleeve 17, the cutter 18 being mounted in said sleeve 17, extending the rod 15 by means of a flywheel 19. The rod 15 is rotated around the longitudinal axis by means of a worm gear 20. Stack The 16 turns the flywheel 21. The sleeve 17 is moved with the cutter 18 by the flywheel 22.
    Combustible gas is supplied through three valves 23, 24 and 25 mounted on the console 8, and the valve 25 is continuously adjustable using an additionally connected pneumatic actuator 26. This valve is primarily intended to supply oxygen to the cutter. In addition, on the base 2 there is a bracket 27, on which the control panel 28 is mounted with the corresponding switches and control lamps. On the base 2, the drum 29 with cams 30 is also strengthened, by means of which automatic adjustment is carried out.
    The turntable 3 is designed so that an ingot 31 can be mounted and fixed on it. For this purpose, movable insert spikes 33 are located on the table plate 32, in addition, the plate 32 is rotatable around the axis 34, and its rotation speed is regulated. Speed control is carried out from the control panel 28. The rotations of the drive are installed either in the base 1 or under the floor, as is usually the case, and a connection is provided to ensure the synchronous rotation of the drive with the drum 29.
    In order to separate the ingots of the 31 gates 35, the ingot is first installed and fixed on the plate 32 of the rotary table 3 so that its axis of symmetry coincides with the axis of rotation 34 of the rotary table 3. Then, adjusting the position of the intermediate element 6 in the vertical direction, the torch is roughly adjusted 18,. Then, using the fine adjustment elements 22, 21, 19 and 20, the cutter is positioned exactly in the cutting plane. After that, the cutter 18 is turned on, regulating the supply of oxygen with the help of the valve 24, the heating time is set and, by strengthening the supply of oxygen by means of the valve 25, the cutting is performed. The valves 24 and 25 regulate the oxygen supply. The hydraulic actuator 12 brings the cutter very close to the contour of the sprue 35, while the rotary table 3 is simultaneously rotated, and the rotational speed is small and corresponds to the speed of the cutting process. Management of these processes: they are conducted from the remote control 2.8. Upon completion of the separation of one lithic, the rotation of the rotary table 3 is accelerated for as long as the next ingot with heating valve valve 24 begins. Then, using a hydraulic drive 12, cutting is performed, followed by movement of the cutter 18. Since the brake discs are fed for processing in large batches and the sprues are located at the same place, the drum 29 containing cams 30 is then actuated. With the help of the coupling coupling 36 at the beginning of the cutting process, it is connected to the drive operating from the turntable 3, and this drive also determines the operating mode of the reel 29. From the following brake discs, the sprues are automatically separated. Usually it is enough to have a ten-cam cam drum of variable shape, and you should pay attention to the fact that during an unexpected accident you should immediately stop the automatic regulation of the process and transfer to manual regulation by disengaging clutch 36..

    The residuals on the surface 37 of the ingot 31 residues and the gate 35 are removed in a very simple way. For this, the cutter 18 is mounted horizontally, and the console 8 is moved until the end of the cutter 18 is at an unsuitable distance from the surface 37. Using the hydraulic actuator 1 2, the required vertical distance is established, after which the above described process can be performed cutting, and the relatively smooth cutting surface significantly reduces the mechanical ofina, surface treating 37. Automatic processing of such ingots allows you to simultaneously perform a cutting operation on one turntable, and on the other GIH install bars. This significantly reduces preparatory final operations. Reliable operation of the proposed device, in particular, is provided by hydraulic actuators equipped with appropriate stop devices, due to which hydraulic actuators can be permanently locked in a fixed position regardless of whether pressure is maintained in the unit or not. In addition, other additional safety devices can be installed that are relatively simple to be mounted on the installation. It goes without saying that other variants of the invention are also possible, the construction of which, however, does not go beyond the design described in the application, for example, automatically setting the gas cutter instead of manual, another known adjusting device, for example a computer with a magnetic or perforated tape for automatic control of the cutting process. In addition, instead of hydraulic actuators, pneumatic or electric actuators can be applied.
