Definitions

  • the invention relates to a device for the axial locking of support, work and / or intermediate rolls in a roll stand or other systems with locking characteristics, for example a CVC roll stand, with a mountable for support rolls on the roll stand and for work and intermediate rolls on the bending system or roll stand , a locking plate having a locking guide and with a for the actuation of the locking plate on the one hand on this, on the roller stand or on another mounting level arranged hydraulic piston / cylinder unit.
  • a disadvantage of this known or a similar type of construction is, on the one hand, the overall height, which restricts the available space for arranging, for example, scaffolding piping and / or for other components.
  • Another disadvantage is the number of components required, such as a rod head with a spherical bearing, a support frame, a cylinder with a pivot rod and a spherical bearing, bolts and securing elements, hydraulic hoses, special screws and washers. Overall, this results in a comparatively high outlay for production, assembly and maintenance.
  • the point of action of the piston / cylinder unit in a plane of attack that is spaced apart from the guide level causes a harmful tilting moment of the locking plate in its guide, which is therefore particularly susceptible to wear and requires maintenance, and can also tend to jam at most.
  • the invention has for its object to significantly simplify the device of the type mentioned, both in terms of the number of components required and their design, with the aim of drastically reducing the cost of manufacture, assembly and maintenance.
  • this device has a locking plate (11) arranged on the mounting plane (zz) of a roll stand (4), which in the guide formed between the plane (zz) and the guide elements (13) is displaceable in the direction of the double arrow (14) and is designed, for example, to be able to engage in an engagement recess (40) in the chock of a roller.
  • a fork head on the locking plate (11) (34) is arranged, while on the assembly level (zz) of the roller stand (4) a support bracket (36) is provided.
  • the hydraulic piston / cylinder unit with the cylinder housing (21) with swivel rod, rod head and spherical bearing (35) and (37) is articulated.
  • This arrangement has the disadvantages mentioned above.
  • FIGS. 2 and 3 show an improved and simplified device in an embodiment corresponding to the invention and can be seen from the synopsis thereof.
  • the cylinder housing (21) in a symmetrical configuration, has outlets (22, 23) on both sides of a plane (yy) that intersects it perpendicularly, for an extended piston rod (24) that can be guided in both directions of movement according to the double arrow (14) and has an approximately pistons (25) which can be loaded on both sides in the center.
  • the locking plate (11) and the locking guide (10) have a window-like recess (1) that corresponds at least to the length of the piston rod (24) and the width of the cylinder housing (21).
  • the cylinder housing (21) with loose contact of both piston rod ends (26, 27) is arranged on both mutually opposite surfaces (2, 3) which run transversely to the direction of movement of the locking plate. It is fixed with a centering (15) on the roller stand (4) or 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 engages z. B. in a recess (40) of a chock (41) of a roller, for example a backup roller.
  • the arrangement of the recess (1) in the locking plate (11) and in the locking guide (10) can be seen in particular from FIG.
  • the displacement position of the locking plate (11) to the left can be recognized by the piston rod (24) emerging from the cylinder housing (21) to the left. This is supported loosely 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) is in loose contact with the surface (3) of the recess (1) follows.
  • the number (4) indicates the surface of the roll stand or another assembly level, depending on which part of the roll stand or other systems the device is arranged.
  • the locking plate (11) is designed to be able to interact directly without mechanical connection with the piston / cylinder unit (20, 21) or with its piston rod ends (26, 27).
  • the cylinder housing (21) has flow channels (16, 17) for a working medium in the upper region and a centering projection (15) which can be engaged in a compatible centering recess (5) in the lower region as shown in FIG. 2.
  • the piston rod guide (19) with holding cover (18) is arranged for easy maintenance.
  • the locking plate (11) has lubricant channels (8, 9) to form a hydrostatic lubricant sliding layer. This almost eliminates the sliding friction between the locking plate (11) and the guide (4, 10) and enables easy sliding with practically maintenance-free and unlimited availability of the device.
  • the lubricant channels (8, 9) can be seen both from FIG. 2 and from FIG. 3 and therein in particular in their arrangement transverse to the direction of movement of the locking plate (11) according to the arrow (14).
  • FIG. 4 shows an exemplary arrangement of two devices (50 or 51) for axially locking support rollers (31, 32). From this it can be seen that the devices (50 and 51) can be easily integrated into the rolling stand or other systems due to their uncomplicated design and can be arranged there with little effort and construction volume.
  • FIGS. 2 and 3 The embodiment of the device according to the invention shown in FIGS. 2 and 3 is merely of an exemplary nature, wherein Modified versions are also within the scope of the invention, provided that they correspond to the construction principle of the main claim.
  • FIGS. 5a and 5b An arrangement of the locking device within a CVC displacement device is shown in FIGS. 5a and 5b.
  • the locking plate (11) is guided hydraulically or pneumatically in one or the other direction of the double arrow (55) in a recess (54) of the sliding block (53) by the piston rod (24) of the cylinder housing (21) and moves and engages one of its ends (56) or (57) one time in the recess (51) of the work roll component (50) or the other time in the recess (58) of the fixed block (52).
  • the cylinder housing (21) is very advantageously attached to one of the piston rod exit surfaces (60). In the example shown, this is a wide flange (60) which rests on both sides on shoulders of the displacement block (53) within the recess (51) and is screwed to it, for example.
  • the locking plate (11) thus locks the sliding block (53) with the work roll component (50) during the rolling operation.
  • the sliding block (53) can be locked with the fixed block (52), thereby preventing its unwanted movement (FIG. 5b).
