Definitions

  • the invention relates to a device for axial Locking support, work and / or intermediate rolls in a roll stand or other systems Locking characteristic, for example one CVC roll stand, with one for support rolls on the roll stand and for work and intermediate rolls on the bending system or Fastenable roller stand, having a locking plate Bolt guide as well as with one for the actuation of the Locking plate on the one hand on this, on the roller stand or on another assembly level arranged vulnerable hydraulic piston / cylinder unit.
  • Locking characteristic for example one CVC roll stand, with one for support rolls on the roll stand and for work and intermediate rolls on the bending system or Fastenable roller stand, having a locking plate Bolt guide as well as with one for the actuation of the Locking plate on the one hand on this, on the roller stand or on another assembly level arranged vulnerable hydraulic piston / cylinder unit.
  • the point of attack causes the piston / cylinder unit in one a harmful overturning moment from the attack plane spaced apart from the management level the locking plate in its guide, which in particular bel pollution is susceptible to wear and tear and requires maintenance, and at most also may tend to jam.
  • FR-A-1 122 538 From FR-A-1 122 538 is a dodging of the chocks in the axial direction enabling device for axially fixing the rolls of roll stands known in their stands, with perpendicular to the axial direction of the rollers led bars. With these bolts the chocks are opposite the stands.
  • the bars act at least on one side of the roller with wedge surfaces directed obliquely to the roller axis with the same slope provided wedge surfaces on the chocks with compliant pressure, the by pressurized pistons of lifting cylinders arranged in a fixed position is generated by moving the latch.
  • the invention has for its object the device of the aforementioned To simplify design significantly, both in terms of number required components as well as their constructive training, with the aim of reducing costs for manufacturing, assembly and maintenance.
  • Figures 2 and 3 is an improved and simplified Device in an embodiment corresponding to the invention shown and recognizable from their synopsis.
  • This Version has the cylinder housing (21) in a symmetrical Formation on both sides of a perpendicular cutting Level (y-y) exits (22, 23) for one in both Direction of movement can be exited according to the double arrow (14) guided extended piston rod (24) with an approximately in the middle attached pistons (25) which can be loaded on both sides on.
  • the locking plate (11) and the locking guide (10) have one at least the length of the piston rod (24) and the width of the Cylinder housing (21) corresponding window-like recess (1) on.
  • the cylinder housing is within this recess (1) (21) with loose contact of both piston rod ends (26, 27) both transverse to the direction of movement of the locking plate mutually opposing surfaces (2, 3) arranged. It is with a centering (15) on the roll stand (4) or fixed on another assembly level.
  • the locking plate (11) is to the left through the piston rod (24) or the piston rod end (26) advanced and attacks z. B. in a recess (40) Installation piece (41) of a roller, for example one Backup roller, a.
  • the arrangement of the recess is in particular from FIG (1) in the locking plate (11) and in the locking guide (10) detect.
  • the Position of the locking plate (11) to the left through the emerging from the cylinder housing (21) to the left Piston rod (24) recognizable. This is loosely supported with the Piston rod end (26) against the surface (2) of the recess (1) in the locking plate (11), while the opposite Piston rod end (27) in loose contact with the surface (3) of the Recess (1) runs along.
  • With the number (4) is the surface of the roll stand or another mounting level, depending on which part of the roll stand or other Systems the device is arranged.
  • the Measure be used that the cylinder housing (21) in the upper area flow channels (16, 17) for a Working medium and in the lower area one in a compatible Centering recess (5) engaging centering projection (15) has, as shown in Fig. 2.
  • the Piston rod guide (19) with retaining cover (18) is included arranged for easy maintenance.
  • the locking plate (11) lubricant channels (8, 9) for Formation of a hydrostatic lubricant sliding layer having. So that the sliding friction between the locking plate (11) and guide (4, 10) almost canceled and an easy one Glide with practically maintenance-free and unlimited Availability of the device reached.
  • the Lubricant channels (8, 9) are both from Figure 2, as also from Figure 3 and therein in particular in their arrangement transversely to the direction of movement of the locking plate (11) after Arrow (14) recognizable.
  • FIG Devices (50 or 51) An exemplary arrangement of two is shown in FIG Devices (50 or 51) for the axial locking of Back-up rollers (31, 32) shown. From this it can be seen that the devices (50 and 51) due to their uncomplicated Can be easily built into the roll stand or other systems Let integrate and there with little effort and Construction volume can be arranged.
  • 5a and 5b show an arrangement of the Locking device within one CVC shifter shown.
  • the locking plate (11) directly in a recess (54) of the sliding block (53) through the piston rod (24) of the cylinder housing (21) hydraulic or pneumatic in one way or another Directed by the double arrow (55) and moves and engages with one of its ends (56) or (57) once in the recess (51) of the work wagon building piece (50) or the other time in the recess (58) of the fixed block (52).
  • the arrangement of the cylinder housing (21) is very advantageous one of the piston rod exit surfaces (60) is attached. This is a wide flange (60) in the example shown, the on both sides on the shoulders of the sliding block (53) inside the recess (51) rests and with this, for example is screwed.
  • the locking plate (11) thus locks during the rolling operation the sliding block (53) with the work roll component (50).
  • the sliding block (53) can be used with the Fixed block (52) can be locked, causing its unwanted Movement is prevented (Fig. 5b).
