Definitions

  • a device for use in metallurgical plants for rounding the edges of strip ribbons which have been separated from a large sheet of steel and which is arranged to operate on the ribbons when they are moved through a single plane includes a mounting shaft arranged on each side of the ribbons upon which the rounding tools are mounted.
  • a feature of the construction is that the rounding tools are arranged in pairs on respective opposite sides of the ribbons and they include rounding flange formations to round both the tops and the bottoms of the ribbons.
  • At least two rounding tools are combined into a single unit so that a central spacer disk or rounding flange element serves to round both the tops and bottom edges of two adjacent ribbons which are fed between the combined tool formation.
  • the construction is such that rounding on the top and bottom of the separated ribbon may be effected at a single level of operation, and thus the expense of operating at more than one level is avoided.
  • This invention relates in general to metal-forming devices, and in particular to a device for use in association with a longitudinal divider for strip steel for machining the longitudinal edges of the strip ribbons obtained by the division.
  • a device for machining the longitudinal edges of the strip ribbons obtained by the division of the strip ice material by employing at least one pair of oppositely set tools for the machining of each longitudinal edge The arrangement is such that it will not be necessary to move the individual strip ribbons out of their normal positions, and it is therefore not necessary to pull the individual strip ribbons apart into different planes or to twist them or to set them upright.
  • the invention discloses an arrangement of tools facing one strip side on one or more axes or shafts which lie parallel to the strip surface and at right angles to the running direction of the strip. This arrangement may be such that the straight line intersecting the medium line of the two axes or shafts of a pair of tools extend normally to the strip surface.
  • two tool pairs are arranged side by side between two strip ribbons to form one bilaterally operative tool pair. Similar arrangement is effected using a spacing sleeve between the two tools arranged on one axis or shaft for the edge machining of the strip ribbon.
  • the subdivision of the spacing sleeve provides means for making the device usable on a short time basis and at little cost for a variety of strip widths.
  • the division sleeves may advantageously comprise a material such as iron or plastic, the latter having the advantage of greatly protecting the surface of the strip.
  • an appropriate arrangement is to combine the tools as one unit for the machining of both edges of strip ribbons which are arranged in a constantly alternating sequence on one end of the other of the axis or shaft. It is also advantageous to arrange the tools in a combined manner as one unit for the machining of both edges of a strip ribbon which is freely movable in axial direction on the axis or shaft.
  • the rounding device may be installed in an existing system for the longitudinal division of steel sheets into individual ribbon strips and which does not require moving the individual strip ribbon out of their normal position.
  • the tool axes are set parallel to the strip surface rather than as before at right angles thereto. It has thus become possible to round several strips alongside each other without having to move them out of their normal position.
  • a further object of the invention is to provide a rounding device for steel strips and the like in which the steel may be continuously moved after it is formed and in the same plane while the edges thereof are rounded.
  • a further object of the invention is to provide a rounding device which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1a is a front elevational view of a device for rounding two strip ribbons which run alongside each other, with the mounting tools firmly mounted on two separate shafts as constructed in accordance with the invention;
  • FIG. 1b is a side elevational view of the rounding apparatus indicated in FIG. 1a;
  • FIG. 2a is a view similar to FIG. 1a of another embodiment of the invention.
  • FIG. 2b is a view similar to FIG. 1b of the embodiment indicated in FIG. 2a;
  • FIG. 3a is a view similar to FIG. 1a of still another embodiment of the device.
  • FIG. 3b is a view similar to FIG. 1b of the embodiment shown in FIG. 3a.
  • FIGS. 1a and 1b shows a diagrammatic representation of a device for rounding the edges of strip ribbons which are arranged to run along-side each other in the same plane.
  • the rounding tools are mounted on two separate shafts, an upper shaft being offset from a lower shaft 5'.
  • the strip ribbons 1a and 1b of steel are directed between spacer disks 2, 2a and 2b.
  • the spacer disks are separated and maintained at a selected distance from each other by spacing bushings 3 and 3a.
  • the edges of the strip materials 1a and 1b are rounded by means of rounding disks 4, 4a and 4b.
  • the rounding disks 4, 4a and 4b may be designed as needed either as smooth disks for initial rolling or as toothed disks for initial filing or initial milling of the edges. All of these elements are arranged on the respective shafts 5 and 5 which may be driven in the same direction or in opposite directions.
  • the spacer disk 2, the spaced bushing 3 and the rounding disk 4 are assembled over the shaft in a desired orientation and are held together by clamping ring 6 and bushing 7.
  • rounding tool assemblies 20 and 22 are arranged on respective mounting shafts 2 4and 26.
  • the assemblies 20 and 22 include the same spacer disks 2, bushings 3, and rounding disks 4 as in the previous embodiment. They are mounted, however, on the respective shafts 24 and 26 for adjustable longitudinal movement in respect to the associated shafts.
  • the shafts are provided with slots 24a and 26a which facilitate the longitudinal displaceable movement of the tool sets by parts, such as a key (not shown), which engage in the respective slots. In this manner, the rounding sets 20 and 22 are able to yield to a different lateral pressure for the individual strips.
  • the shafts 24 and 26 are rotatably mounted in end pedestals 28 and 30, respectively, in vertical alignment.
  • two sets of shafts are employed in vertically spaced relationship, .32 and 34, and 36 and 38.
  • the shafts 32 and 34 are arranged on respective opposite sides of the strip ribbons being treated 40a, 40b, 40c and 40d.
  • the shafts therebelow 36 and 38 are also arranged on respective opposite sides of the ribbon material being rounded.
  • Complete rounding tool assemblies generally designated 42 and 44 are arranged on the shafts 32 and 34 in a manner such that there is an alternate spacing between each set, so that alternate ribbons 40b and 40d are operated upon by rounding assemblies 46 and 48 which are carried by shafts 36 and 38.
  • the assemblies 42, 44, 46 and 48 may advantageously be mounted so that they may be displaced along their respective shafts and adjusted in a displaced position.
  • one or both of the shafts may be driven, or the strip material may be wound so that it is pulled through the rounding device.
  • a device for rounding the edges of ribbons of material such as steel which is separated into'a plurality of ribbons which are moved in substantially one plane away from a large steel sheet from which they are separated comprising a shaft arranged on each side of the ribbons to be rounded substantially parallel to the surface of said ribbons, and a rounding tool carried on each of said shafts and disposed at right angles to the running direction of the ribbon in locations to round the top and bottom edges thereof substantially without directing the ribbons out of the plane at which it is being moved, said shafts being aligned vertically.
  • a device for rounding the edges of ribbons of material such as steel which is separated into a plurality of ribbons which are moved in substantially one plane away from a large steel sheet from which they are separated comprising a shaft arranged on each side of the ribbons to be rounded substantialy parallel to the surface of said ribbons, and a rounding tool carried on each of said shafts and disposed at right angles to the running direction of the ribbon in locations to round the top and bottom edges thereof substantially without directing the ribbons out of the plane at which it is being moved, said rounding tools being displaceable axially along said shafts.
  • a device according to claim 3, wherein said bushings and said spacer disks are axially movable on their associated axle means.
