Description

The invention relates to a device for the a-regulative control of the shear plane by the support of the spikes of the same type as the direct irradiation of the primary and primary components and solves the problem of synchronization with the velocity of the resin. " stratified sheet "

The flying spits of the hot-line lines,, and more: hot-rolled sheet metal, are structurally demanding devices, mainly for the transport. O-governmental workflow, t. j. the novelty, but also the accelerated poor running, is provided, depending on the speed of the strip and the selected sheet, for the purpose of returning to the original position and eventually moving to the shear. planes and pcd. This relative velocity is more accurately determined by the circumferential velocity of the vesicles. a straightener whose fast one is a regular chio <i> -dialing line, or is ready to handle it.

Riaidial drive of the support of flying spit roots is either electromotoric or predominantly hydriauilic with the aid of straight-line hydromioiton. With the aid of primary regulating fastening elements of the hydraulics, the fast running speed of the slide is adjusted with the line speed being exceeded, which must then be synchronized with the speed of the belt by braking the slide. , secured mechanically, ie by transferring from a straight-line coupling to a ridge gear to be braked to the synehirone in the work station. The solution has a number of disadvantages, which often require the mechanism to work and operate without a rladein synchrony, ie, essentially only on the basis of the scattering of the tolleirectic scattering and the frequent thawing adjustments of the allyl control elements. hydraulics. Also, when the coupling is mechanically coupled, which is violent with frequent biases in the mechanism, which results in a low lifetime of the mechanical elements, there is a relatively rigid array of precisely bounded and precisely mentioned objects to precisely stir the panels. -mall pre-written tolerariaroia, little reliable.

The above-mentioned drawbacks are solved and the above-mentioned problem is solved by a more sophisticated method for automatically regulating the shear plane of the flight-beam support provided with the hydraulic, point-and-point purpose of the present invention. between the intermediate generator and the directional distributor of the hydraulic control systems of the hydrometeritor, the dosing roto-hydraulic motor is provided with the gearbox through the hub. coupled with the drive of ro-v-pickups. The rotary dosing rotary dosing unit is provided with additional pressure medium supply and discharge pipes, with additional vapor retarders for the straightener, along with a plunger vent to smooth out the deflection of the straightener. The diaphragm hydroimctoira is a pira-diaphragm-free. pressure peak valve. In particular, the present invention is concerned with providing a reliable synchronization of the speed of the flying rods, especially in the shear plane, with the speed of the shear plate and thereby ensuring the total length of the shear blades. The arrays are simple to recrystallize on operating lines, using elements of this secondary irrigation on the same base, i.e., hydraulic. An example of the embodiment of the inventive device is shown in the accompanying drawings. drawing with a schematic layout of hydraulic elements and lines with line marking, and flying options.

The equipment in the above-mentioned equipment consists of a piriaimio-hydraulic fluid 23 mounted on a line of which a support 21 with a sulphurous tube of 22 flying spitters 20 is attached to the rod. media from hydrogenerate-cra 32s pohcrolm 33, to which displacement is u-. a multidirectional directional valve 34 with outlet to the individual chambers of the borohydride 23 and with said single-directional working stage 35 of the supernatant 21 parallel to the control valve 43 of the slide-to-sleep slide speed. The pressure regulating elements continue to consist of a Mokovainia control distributor 41, coupled to a reclosable manifold valve 42, for a low level straightener. The apparatus continues to be equipped with a reversing stop cam 24, a stop 44 hydraulics 44, and a stopper 45 for operating the slide. In front of the directional transducer 34, a metering rotary hydraulic motor 51 is disposed, in front of which the conduit is fed into the tank 31 and is provided with a suction valve 52 for working the straighteners. Behind its extrusion, a similar expansion of the auxiliary circuit is provided with a suction valve 53 of the straightener coupled to a recirculating variable valve 54 of the backward straightener. The dosing rotary hydromotor 51 is provided with a gear 5S connected to a drive 11 of the straight line 10. At the outlet pipe 38 of the carriage is a straight line from the straight-line hydromio-radiator 23 is a prop-preplet valve with 55 pressure peaks.

The source of the pressurized fluid for the propellant hydromotor 23 is a hydrophobic acid 32 which pumps the oil from the tank 31 through a separate metering rotary hydraulic motor 51 into a directional-flow condenser 34 and thus into the individual chambers - directly or hydraulic fluid. 23. During line stop or shutdown

In the case of a straightforward hydromotor 23, it is discharged by the set fastener 21. In the case of a speed equal to the speed of the straightener drive 10, the rataonator 51 is pumped from it only by the volume that is pumped by the hydrogenerateir. 32a are stitched at pressures with the primary control elements. In the case of a lower drive speed and rollers 13 of the straightener 21, the lowering speed of the metering motor 51 reduces the volume of the medium and simultaneously the shock absorbers displacing the impedance hydraulic motor in the axes of the directional distributor 34. 23, thereby synchronizing their fish. Conversely, in the case of a higher leveler straightener 10, the dispenser hydrosulfurizer 51 pours through the suction valve 52 a further medium into the stiffener, thereby increasing the pressure and the working speed of the straight-line hydromotor 23.
