  • ABSTRACT Herkamp Attorney, Agent, or Firm-Brumbaugh, Graves, Donohue & Raymond [57] ABSTRACT Method and apparatus for the continuous production of welded light-construction beam sections, particularly land T-beams, wherein the web and the flanges of equal wall thickness are slit from a single strip of rolled steel, brought together into the desired cross sectional form and joined by longitudinal-seam welding.
  • Strip guiding devices are provided which preferably comprise vertically and horizontally displaceable arms and run-in rollers.
  • one of the strip guiding devices is rotatable about a horizontal axis.
  • This invention relates to a method of continuously producing welded light-construction beam sections, in particular I- or T-beams which may have profiled flanges and a profiled web of rolled steel strips, wherein the strips of equal wall thickness forming the flanges and the web are joined by longitudinal-seam-welding.
  • each strip part i.e., the strip for the web and the strips for each flange, respectively is taken from a feeder group of its own, consisting of an uncoiler, a flattener, a looper and a welding device for joining a strip end with the beginning of a new strip.
  • the individual strips are then brought together in the desired position relative to each other and are welded to form a beam section.
  • the sheet coils for the individual strips have differing lengths. Therefore as in a continuous operation the strip end of one coil must be transversely welded with the beginning of thestrip of the following coil, it is inevitable that the transverse welding seams both of the flanges and of the web according to the differing lengths of the two strips lie at different points on the finished beam, sometimes relatively far apart.
  • the transverse welding seams which affect the mechanical properties of the beam, must then be cut out, which results in a relatively high waste and many short lengths of the finished beams.
  • This invention has as its object the avoidance of the described disadvantages and difficulties. It is particularly an object of the invention to make the continuous production of welded light-construction beam sections, such as I- or I-beams, more economical than-in the past, to simplify the construction of the plant and to make it reliable, thereby reducing stoppages to a minimum and decreasing the waste and reducing the operating staff.
  • the object of the invention is achieved by a process for continuously producing welded light-construction beam sections, particularly I- or T-beams, having, if desired, profiled flanges and/or a profiled web, wherein the strips of equal wall thickness forming the flanges and the web are joined by longitudinal-seam-welding.
  • the strips forming the flanges and the web are slit from a single strip of rolled steel and after trimming of their edges the individual strips may be brought together by guiding devices to form the desired cross section.
  • the strips forming the flanges and/or the web are profiled either before they are brought together to form the desired cross sectional structure or after they have been welded.
  • profiling after welding is that, while the strips are brought together to obtain the desired cross sectional form, one need not yet take into consideration the increased rigidity, which is achieved by profiling, i.e., one can work with smaller radii of curvature, which takes up less room.
  • the invention also comprises a plant for carrying out the described method.
  • Thisplant is characterized in that a sheet slitting device is arranged be h indtlie uncoiler for the sheet coils and guiding devices are provided for bringing together the slit strips in the desired cross sectional form.
  • the guiding devices for the strips suitably consist of guiding arms, displaceable vertically and horizontally and at least one pertaining pair of run-in rollers each.
  • At least one strip guiding device is rotatable around a horizontal axis, so that at least one strip may be twisted from the horizontal into the vertical.
  • the cutting or slitting device, the trimming device and the chip breaker, necessary for slitting the broad strip, do not involve any additional costs, because it is also in a known conventional plant that a broad sheet strip has to be first divided into three strips on a separate longitudinal dividing device, a trimming device with chip breaker, etc. and it must then be coiled up again, or one has to buy three considerably more expensive narrow, already divided sheet coils, instead of an untrimmed and less expensive hot rolled strip.
  • the main advantage of the invention lies in the fact that the stoppage periods caused by introducing a new sheet coil and welding it on to the previous coil end, are considerably diminished. Whereas formerly these stoppage periods amounted to about 50 percent of the entire production time, they come up to not more than about 20 percent with the plant of the present invention. If oneallows for all the other stoppage periods for maintenance and changing tools, this means that the productivity of the plant is increased by about 35 percent.
  • Strip 12 serves for forming the web and the strips 13 and 14 form the upper and the lower flanges, respectively.
  • the strips can be trimmed, if desired, and the cut off edges may be crushed into small strips-by a scrap crusher 1 5 and removed by a, conveyor belt 16.
  • the strips l2, l3, and 14 pass via a second looping table or looping pit l7'and after having passed guiding arms 18, 18' and 18", which are adjustable to different heights, and deflexion rollers l9, l9, and .19", the strips passto strip guiding devices 20, 21, and 22, each of whichpertains to one of the strips.
  • One of the guiding arms, i.e., the guiding arm 18 for the strip 12 is rotatable around a horizontal axis, so that the strip 12 may be twisted into a vertical position.
  • the guiding arms 18, 18', and 18" may also be horizontally displaceable transversely towards the direction of the passing strips, as is indicated by the double arrows (FIG. 4) to enable an adjustment of the plant strips of different widths.
  • the guiding device 20 for the web strip 12 and the guiding devices 21 and 22 for the upper flange strip 13 and the lower flange strip 14, respectively, are advantageously provided with adjustable pairs of run-in rollers and possibly with additional guiding elements (rollers, ledges, or the like), which guarantee a reliable guiding of the strip passing throughj
  • These strip guiding devices may suitably be horizontallydisplaceable on sledges, transversely to the direction of the passing strip.
  • any desired off-center position can be approached which therespective strip coming from the looper requires.
  • the device is displaced laterally, until the center of the strip lies in the'respective production line. Lateral dislocations and ktorsions of the strips can be accommodated by the loops formed in the preceding looping pit l7. 1
  • the profiling machines 23' and 23" can be omitted and insteadof them a profiling machine 23" may be provided behind the pull-out driving device 25, as is indicated in FIGS. 1 and 2 in dotted lines.
  • the finished I-section is profiled.
  • FIG. 5 which illustrates a section of the profiling machine 23" transverse to the direction of travel of the beam, the step'of profiling the upper flange is shown.
  • Reference numbers 29 and 30 refer to profiling rolls of machine 23".
  • the finished sections pass via a roller table 31' to a piler 32, from wherethey are'taken away.
  • strip stock to continuouslyform a web and at least one flange constituting strips, passing the web and flange constituting strips as they are formed through guiding devices to bring the strips together into the desired cross-sectional form by rotatingat least one of the web and flange constituting strips, into a plane different from the plane of the other constituting strips without changing the orientation of the as yet unslit portion of the single strip, and joining the web and flange constituting strips by longitudinal seam welding after the continually formed strips are brought-together.
  • An apparatus for continuously producing welded light construction beam sections, particularly 1 and T beams, having a web and at least one flange of equal wall thickness from a single strip which comprises a sheet coil supply and uncoiling means a sheet slitting means arranged after the sheet coil supply and uncoiling means and adapted to progressively slit the end of the single strip to continuously form web and flange constituting strips,
  • strip guiding means for orienting and bringing the strips together into the desired cross-sectional form by rotating at least one of the strips into a plane different from the plane of the other strip without changing the orientation of the sheet coil supply
