Definitions

  • the invention relates to a device for acting on the guide surfaces of, guided in the stator windows of rolling stands bearing chocks with auflegbaren on the guide surfaces printing plates, which are acted upon by arranged in the rolling mill stands hydraulic piston-cylinder units.
  • Devices of this kind are for example off EP-A 1 036 605 and EP-A 1 281 449 known, in which the hydraulic piston-cylinder units are arranged in recesses of the roll stand, and the respective cylinder piston carries on its, the stator window and the respective lateral guide surface of the bearing chocks facing end face a pressure plate.
  • the invention has for its object to eliminate this, affecting the rolling process disadvantages.
  • This object is achieved in that the hydraulic cylinders are each assigned control devices which can be controlled by pressure and displacement measuring devices. These arrangements may operate such that the piston, regardless of the force acting on it, maintains a predetermined position or so as to yield at a certain force acting on the piston, and approaches another particular position; they can also work so that the bearing insert is pressed with a certain force to a fixed stand window side.
  • the Weggeber then shows no changes. If the piston of the cylinder is then driven by a predetermined amount in the opposite direction, so there is a defined game of bearing chocks in the stator window.
  • This type of clearance adjustment can compensate for the manufacturing tolerances of the different bearing chocks, the wear and the St Seinschnürung due to the expected rolling forces. By setting an optimal game no pressure forces of the piston and no frictional forces are generated, which negatively affect the controllability of the process.
  • the position of the bearing chocks can be determined to a selected level by pressing and simultaneously measuring the driven piston stroke on the drive side and on the operating side of the rollers. If this distance measurement compared with previously stored distance measurements, then the wear can be determine the stud windows and their components. If the piston is used as described so that there are two pistons per roller and they press over the bearing chocks on a fixed surface, so that the setting of the rollers can be determined. By evaluating the measured values, the position of all rolls can be determined among each other. If a piston is provided for each bearing chock on each side, the inlet and the outlet side and the drive and operating side, the rollers can be selectively interlocked against each other via this path measurement. So z. B.
  • the upper work roll and the upper support roller are placed parallel to each other and compared to the lower work roll and the lower support roller, which are placed parallel to each other are entangled.
  • This setting of the upper rolls to the lower rolls can then be used to influence profile and flatness.
  • the position of the rollers can be precisely positioned.
  • FIG. 1 can be seen in the stator window SF, the bearing chuck LS for the horizontal roller between the two uprights ST1 and ST2 a rolling mill out.
  • the left stand spar ST1 is a piston-cylinder unit which has a guide cylinder FZ with a guided therein piston K with piston rod KS.
  • the piston rod KS carries at one end a guided in the left stand spar ST1 pressure plate DP.
  • Piston K and Piston rod KS have centered on a recess AS, in which a, arranged on the outer rear wall of the guide cylinder FZ odometer WM projects.
  • On both sides of the piston K open into the guide cylinder FZ hydraulic pressure lines HD, which is associated with a pressure measuring device, not shown.
