    The invention relates to polygraphy, in particular to a method and device for fastening and adjusting a printed Atrica on a form cylinder of a rotary printing machine .. 5
    The purpose of the invention is to increase the reliability of fastening the matrix.
    The method of mounting and adjusting the printing matrix consists in inserting one parallel of the axis of the cylinder iO to the end of the printing matrix between the jaws of one of the grips located in at least one axial slot of the stern cylinder, and clamping it, placing the matrix on the sides of the cylinder surface, inserting another parallel to the axis of the cylinder of the end of the matrix between the jaws of one of the other grippers, clamping it, stretching the matrix and ensuring its tight fit to the side surface of the forme cylinder by moving the gripper Whether grippers inside the slot towards the periphery of the cylinder supply hydraulic fluid to the hydraulic means 25 until a predetermined pressure, and after the tension giva- audio matrix grippers fixed position by mechanical means and relieve the fluid pressure in the hydraulic system 30.
    FIG. Figure 1 shows a part of a cylinder with an axial slot and attachment and adjustment grips, top view. figure 2 - section aa on 35 figure 1.
    The plate cylinder 1 has a groove 2, inside which two grippers 3 and 4 are mounted for fastening the two ends of the 4D printing matrix 5. The gripper 4 is equipped with hydraulic means for moving it in the peripheral direction inside the groove 2 (Figures L and 2. Both grippers 3 and 4 Mounted with the possibility of peripheral movement within the groove. For more fine-tuning the grip 3 can be equipped with a device for its axial movement. The axial adjustment of the matrix SO can also be carried out by axial movement of the form cylinder; 3 are made five from; a version, in which five bolts 6 enter, uprack into the radial wall 55 of the 7th groove 2, adjoin the grip 3. When the bolts 6 are screwed into the holes, their ends abut against the supporting surface 8 of the radial wall 7 and the grip 3 moves inside the groove.
    Two return devices 9, located near the centerline of the groove 2 5, remove the grip 3 against the radial wall 7. Saximr 3 includes a housing 10 provided with means allowing it to move along the bottom of the groove. 2. The surface of the body forms the ng-window of the gripping sponge 3. The second detachable sponge 1I is attached to the body by means of screws 12, which secure the clamps. On the upper surface of the housing 10 there are two pins 13 for fastening the printed matrix, which has for this purpose two corresponding holes.
    The gripper 3 may be a completely stationary element if it is possible to mount the matrix on the cylinder with an image exactly axially. In this case, the matrix fixed on the bars x 13 (of which there are at least two) is set correctly with respect to the cylinder. When assembling the machine, the installation of the fixed grip 3 and the pins 13 should be carried out with greater accuracy. The grip, as well as the grip 3, has a body 14, on the upper surface of which a removable sponge 15 is fixed, held and clamped by means of screws 16.
    The gripper housing 14 has five transverse cylindrical holes, inside which five hydraulic jacks 17 are mounted. Each jack 17 includes a cylinder
    18, installed inside the cylindrical bore of housing 14, porga
    19, hermetically moving inside the cylinder 18. The end of the piston 19 protrudes relative to the side surface of the grip 4 and abuts against the supporting surface 20 of the radial surface 21 of the groove 2 adjacent to the grip 4. The head has a diameter equal to the inner diameter of the cylinder 18 and is equipped with three grooves 22 , inside which are installed sealing gaskets 23, ensuring tightness between the piston head 19 and the cylinder 18.
    The supply of the working fluid to the hydraulic jacks 17 is carried out through the tube 24 connected to the pump. The pressure is monitored by means of a manometer in order to avoid pressure to a value greater than the resistance to deformation of the printing matrix 5 (pump and manometer not shown) . The tube 24 is equipped with five T-shaped nozzles 25 for supplying working fluid to each of the cylinders i 8. Part 26 of each T-shaped nozzle, the perpendicular tube 24, has the shape of a truncated cone and is screwed into the housing 27, which is two screws 28 is fixed on the body 14 of the gripper 4 against the cylinder 18. Part 26 extends into the blind hole 29 of the body 27, which is a continuation of the cylinder 18. The sealing gasket 30 provides a tight seal between the body 27 and the body 14 of the gripper.
    A clamping element 32 is fastened with screws 31 near the center line of the groove 2 on the opposite of each T-shaped port 25, in the upper part of which there is a notch 33 opposite the finger 34 of the housing 27 The finger 34 is a cubic block welded to the housing 27 and having an oval hole 35, the screw 36 passes through the top wall of the notch and is screwed into the lower part of the clamping body 32. A return spring 37 is installed between the two adjacent surfaces of the lower parts of the gripper body 14 and the clamping body radial wall 21 of the groove 2.
    The device works as follows.
    One end of the printing matrix is inserted between the gripping jaws 3 and clamping the latter with screws 12. Tensioning the matrix 5 onto the side surface of the cylinder, inserting its second end into the gripper 4 and clamping it with screws 16. Activating the hydraulic system pump (can be a small hand pump and pump until the pressure gauge shows the allowable amount of pressure. The pressure increases simultaneously in all cylinders 18 where the working fluid enters through the tube 24 and the T-shaped nozzles 25, pressing the pistons 9 to porous surface 20. As a result, the gripper 4 is moved inside the groove 2 and the printing matrix 5 is pulled onto the cylinder. When the pressure of the working fluid reaches the maximum, it can be reached
    My values are tightened by screws 36, which curl the upper part 38 of housing 32 and block fingers 34. From this moment, gripper 4 is mechanically 5 locked in this position. It only remains to relieve the pressure in the working fluid using, for example, a bypass and isolate the pump from the hydraulic system, closing, for example,
    10 connecting valve.
    If the cylinder is intended to fasten several printing dies, for example three, three axial slots are threaded on its side surface
    15 each of which is equipped with two grippers. One gripper serves to fasten one end of one printed matrix, the second end of which is fastened in one of the grips of the next notch, etc.
    The proposed method and apparatus can also be used to fasten and adjust each matrix.
