  • the invention relates to a device for attaching a module to a stand frame of a roll stand.
  • a device for attaching a module to a stand frame of a roll stand according to the preamble of claim 1 is known.
  • a sliding frame with wedge elements is used here, with which the position of a guide unit, through which a rolling stock in the form of a bar is passed, can be adjusted solely in the vertical direction, ie in an upward or downward direction.
  • the object of the invention is to optimize attachment of a module to a stand frame of a roll stand.
  • a device comprises a stand frame of a roll stand and a module in the form of a structural unit formed from a roll fitting.
  • the module can also have a plurality of rolling fittings.
  • the device according to the invention is used to attach the module to the stand frame of a roll stand and to align it laterally, preferably in a horizontal direction towards the center of the strip run.
  • Such a device comprises at least one wedge element which can be arranged between a stop surface of the stand frame and a contact surface of the module.
  • the wedge element can be displaced parallel to a transport direction in which material is moved through the roll stand.
  • the wedge element has a base surface running parallel to the direction of transport and a wedge surface arranged at an angle thereto.
  • the module has a contact surface that is complementary to the wedge surface of the device.
  • the wedge element is arranged in relation to the upright frame or the module in such a way that an orthogonal line directed to the base of the wedge element runs horizontally on the one hand and is arranged transversely to the transport direction on the other hand. With this arrangement of the wedge element it is achieved that by moving the wedge element parallel to the transport direction, a lateral distance of the module from the center of the belt run is variable or can be set to a predetermined value.
  • the feature “strip travel” is the direction in which material is actually moved through the roll stand.
  • This material can be endless strips of metal. However, this material can also be metal sheets that only have a limited length.
  • the invention is based on the essential knowledge that it is possible due to the displaceability of the wedge element parallel to the transport direction Adjust the positioning of the module on the stand frame of a roll stand with regard to a lateral distance from the center of the strip run.
  • a specific position of the module relative to the strip run and thus to the "real" position of the rolling stock within the plant or rolling stand is achieved, in which the module has a predetermined lateral distance to the center of the strip run occupies or has.
  • the module is attached or fastened to the stand frame by means of the device according to the invention and the wedge element is clamped between the stand frame and the module.
  • the use of the present invention is particularly advantageous in the event that the stands of a roll stand or the associated bars of the stand frame of a roll stand do not ideally point vertically upwards, but rather point slightly to the side (outwards or inwards) with their upper end, for example are tilted.
  • the uprights are not aligned parallel to one another, although it is still possible to attach the module to such an upright frame with the aid of the device according to the invention.
  • a module it is possible to attach or fasten a module to a stand frame in a suitable manner, even in the event that, for example, the stand on the operating side is tilted outwards and the stand on the drive side is also tilted outwards, but in one is tilted at an angle other than the operating side.
  • attachment of a module to a stand frame is also possible in the event that one stand on the drive or service side faces outwards or inwards and the other stand (ie on the service or drive side) faces the opposite side respectively is tilted.
  • such a tilting tendency of the stand is compensated for by clamping the wedge elements at the upper and lower edge of the module in different positions between the module and the adjoining stand frame and fastening them there.
  • the base and the wedge surface of the wedge element enclose an angle between them.
  • the contact surface of the module is complementary to the wedge surface of the device.
  • this means that the contact surface is formed or oriented in the same way at an angle, namely at an angle in relation to the transport direction, which is identical to the angle between the base surface and the wedge surface of the wedge element.
  • the wedge element can be provided with at least one through bore which runs parallel to the orthogonal line which is directed towards the base area of the wedge element.
  • Two such through bores are expediently also formed in the wedge element.
  • the mentioned displacement of the wedge element parallel to the transport direction only takes place if the module is newly attached or mounted on the stand frame of a roll stand, or if a position of the module on the stand frame - with loosened Screw connection - to be changed in order to achieve a different distance between the module and the middle of the belt run.
  • the wedge element is firmly attached to the upright frame or is recorded or clamped in a stationary manner between the upright frame and the module when the module is on the Stand frame is attached, for example by means of screws.
  • the wedge element can be displaced parallel to the transport direction in the manner mentioned when the fastening of the module to the stand frame of a roll stand (for example in the form of a screw connection) is released.
  • an end plate which has a lateral projection is arranged adjacent to the base area or wedge area.
  • a front plate and its lateral projection facilitate the displacement of the wedge element parallel to the direction of transport.
  • suitable assembly means e.g. mobile hydraulic cylinders or the like
  • a key can also be provided for the device, which is arranged on an underside of the module.
  • a feather key serves the purpose of supporting the module in particular on a base or a surface located below the module.
  • a vertical positioning of the module relative to the stand frame of a roll stand, to which the module is fastened, is thus also determined or influenced by a suitable dimensioning of the parallel key in the vertical direction or its height.
  • a stop plate is provided for the device with which the module can be attached to the inlet side or outlet side of a stand frame of a roll stand.
  • a stop plate can be provided or arranged on an end face of the module.
  • the module which is part of the device according to the invention is preferably an inlet side module and/or an outlet side module.
  • this is an inlet side module on the Fixed inlet side of a stand frame of a roll stand.
  • a run-out module is attached to the run-out side of a stand frame of a roll stand.
  • a module can be attached or fastened to a stand frame of a roll stand with little effort and a short or shortened assembly time.
  • a lateral distance to the center of the strip run can be changed or adjusted for the module in order to compensate for any misalignment of the roll stand and the associated stand.
  • the present invention is particularly suitable for use in single-stand plants or in multi-stand plants (for example tandem mills).
  • FIG. 1 shows a simplified side view of a roll stand W and an associated stand frame 1, to which a module 12 is attached by means of the device 10 according to the invention, which is explained separately below.
