DEVICE AND METHOD FOR GUIDING METAL STRIPS, COMPRISING GRINDING BODIES WITH SUPPORT ELEMENT

Abstract

A device for laterally guiding (1) a metal strip (2) running over a metal strip conveyor device. The device has at least one main part module (3) with a guiding plane (4) and at least one grinding body with a grinding surface (5a, 5b, 5c) for contacting the metal strip (2) to be guided for guiding purposes. The grinding body (6) is attached to a support element (7), or the grinding body (6) includes the support element (7). The support element (7) is mounted in the main part module (3) in a movable manner in the direction of the rotational axis (10) and in a rotatable manner. The position of the grinding body in relation to the guiding plane (4) is modified by moving the support element (7) prior to or while laterally guiding metal strips running over a metal strip conveyor device, prior to contacting a first metal strip for guiding purposes, and/or while contacting a first metal strip for guiding purposes.

10. A method for laterally guiding metal strips running over a metal strip conveying device wherein the conveying device comprises at least one main body module having a guiding plane and comprises at least one wearing body with a wearing surface for contacting the metal strip to be laterally guided for guiding purposes; the method comprising: guiding the metal strips over the conveying device; rotating the at least one wearing body at which the metal strips are conveyed about an axis of rotation perpendicular to the guiding plane; and modifying the position of the at least one wearing body in relation to the guiding plane by moving a support element to which the at least one wearing body is attached or which comprises the at least one wearing body, the modifying being before the guiding of the metal strip takes place by contacting a first metal strip for guiding purposes, and/or during the contacting of a first metal strip for guiding purposes, and/or in a period of time after the contacting of a first metal strip for guiding purposes and before the contacting of a second metal strip for guiding purposes.

11. The method as claimed in claim 10, further comprising choosing the position of the at least one wearing body in relation to the guiding plane in accordance with a magnitude of the force which is exerted on the at least one wearing body by the metal strip and/or on the metal strip by the at least one wearing body, or is expected for a further metal strip.

12. The method as claimed in claim 10 further comprising modifying the position of the main body module in relation to the at least one wearing surface by moving the main body module during the contacting of a metal strip for guiding purposes, or in a period of time after the contacting of a first metal strip for guiding purposes and before the contacting of a further metal strip for guiding purposes.

13. The method as claimed in claim 10, further comprising, for guidance, placing at least one of the at least one wearing bodies against the metal strip in a pressure-controlled manner.

14. The method as claimed in claim 13, further comprising placing the at least one bearing body against the metal strip by operating a hydraulic adjusting device supported on the main body module.

DESCRIPTION OF THE EMBODIMENTS

Examples

[0042] FIG. 1 shows a segment of a device 1 for lateral guidance schematically in an oblique view. It shows a metal strip 2 which is running over a roller conveyor.

[0043] Main body module 3 has a guiding plane 4 and a plurality of wearing bodies of which only the wearing surfaces 5a, 5b, 5c are illustrated. The wearing bodies are rotatable about axes of rotation perpendicular to the guiding plane. The wearing surfaces are preferably flat, as explained in WO2015043926 and EP17174195.2.

[0044] FIG. 2a shows schematically a wearing body 6, to which a support element 7 is attached.

[0045] FIG. 2b shows schematically a wearing body 6 that comprises the support element 7 in an illustration similar to FIG. 2a.

[0046] In an illustration similar to FIG. 2a, FIG. 3 shows how the support element 8 can be moved in the main body module 9 in the direction of the axis of rotation—this being indicated by a double arrow. The axis of rotation 10 about which the wearing body can be rotated passes through the support element 8. The support element 8 is rotatably mounted in the main body module.

[0047] FIG. 4, which is based on FIG. 3, shows that there is a hydraulic adjusting device 11 for moving the support element. It is supported on the main body module 12. The optionally present device for measuring and/or controlling the cylinder travel 13 is likewise shown.

[0048] Optionally, a device 17 for measuring force exerted on wearing bodies and/or for measuring force exerted on the metal strip is present. Optionally, a device 18 for controlling force exerted on the wearing bodies and/or for measuring force exerted on the metal strip is present.

[0049] Optionally present devices for force- and pressure-controlled strip guidance, e.g. valve stands, have been omitted from the illustration for greater clarity.

[0050] FIG. 5 shows schematically a mechanical adjusting device 14 for moving the main body modules 15a, 15b. The two main body modules 15a, 15b are positioned relative to one another on opposite sides of a sheet by means of a spindle 16, which is indicated by a double arrow.

[0051] Although the invention has been illustrated and described more specifically in detail by means of the preferred illustrative embodiments, the invention is not restricted by the examples disclosed, and other variations can be derived therefrom by a person skilled in the art without exceeding the scope of protection of the invention.
