Definitions

  • the invention relates to a method and a device for covering a drum or a wheel with an endless thin-walled metal jacket.
  • the task is to provide the surface, which requires frequent finishing, with a high-quality material, since the drum itself is made of cast iron. For this it is necessary that this metal jacket tightly encloses the Troa'ime). Due to the size of the drum and the impossibility of dismantling, this tape must be applied on site and the usual methods of thermal shrinking are also ruled out.
  • this object is achieved in that a metal strip is rolled onto the drum and is pressed continuously until it surrounds the drum and overlaps at the ends and then placed this under longitudinal tensile stress and cut, machined, welded and cut at the welding point in this state subsequently worked.
  • this can be done either by rolling the metal strip onto the drum and thereby continuously fastening it with brackets on both edges of the drum circumference until it overlaps with its ends, then preferably starting from the side opposite the overlap point, stepwise clamping blocks are attached to the drum and belt and are pressed apart by means of a tensioning device arranged between them, whereby the band part in between is brought under a predetermined tension until the overlap point is reached, then the band ends overlapping there are cut through and after smoothing the band ends and tensioning for closing of the gap are welded and reworked, or that tensioning straps are rolled on the outside and tensioned after the wrapping is closed, the metal strap being tensioned by friction.
  • FIG. 1 shows the elevation of the entire device
  • FIG. 2 shows the cross-section thereof
  • FIGS. 3 to 6 show the laying on and tensioning in the various stages.
  • 7 shows the cutting and in FIG. 8 the processing of the welded edges
  • FIG. 9 the welding and in FIG. 10 the processing of the finished weld seam is illustrated.
  • Figures 11 and 12 show an enlarged section of the attachment of the clamping elements.
  • FIGS. 13 and 14 show another variant in mutually associated cracks, in which tension belts are used in the initial position, FIG. 15 in an intermediate position and FIG. 16 in the end position.
  • Fig. 17 a fastening element is shown, while Fig.
  • FIGS. 24 and 25 show the own clamping process in an enlarged achsonometric representation.
  • a drum for example a casting wheel with 4.8 m 0, is to be covered with a 1 mm thick, 1.2 m wide stainless steel belt with a defect-free, highly polished surface required for pouring the triacetate raw film.
  • a groove of approximately 10 -12 mm and a width of 40 mm is milled into the drum a (see FIG. 11). If the welding parameters allow (welding current), this groove can be dispensed with.
  • threaded holes i are drilled in the axial direction in both end faces above the shoulder h of the drum a.
  • the metal band b is about 600 mm longer than the circumference of the drum a.
  • the width of the band b is chosen so that it projects to the left and right of the drum a by 30 mm each over the drum width (FIG. 12).
  • the surface to be placed on the outside, on which the product is later poured, is provided with a suitable protective film.
  • These protruding edges have corresponding holes k at certain intervals, which are used to fasten the clamping elements c by means of screws.
  • These clamping elements c are designed so that they can slide along the shoulders of the drum a (Fig. 12).
  • the metal strip b wound on a transport spool is placed in a roll-off stand e and the end of the strip is fastened to the drum a with a clip (FIG. 1 e).
  • the metal strip b is placed on the drum circumference and clipped onto the drum a at the intended intervals on both band edges by means of the tensioning elements c (FIG. 3).
  • a hydraulic press is used between the tensioning element d, which already holds the band b to the drum a, and the next tensioning element c screwed onto the band b - seen clockwise - tensioning the band piece in this area and in the tensioned state with a mechanical turnbuckle f, which is clamped between the clamping elements c, d (Fig. 5).
  • the area of FIG. 5 (sequence 1) is thus fixed in a taut manner.
  • stage of tension (episode 3) is again clockwise, stage (episode 4) is again counterclockwise
  • the hydraulic press is always placed between the tensioning element d screwed onto the drum a and the tensioning element c fastened to the edge of the belt and, after the tensioning of the respective band piece, is replaced by the tension locks f.
  • This hydraulic assembly clamping system has the advantage that the tension can be applied in a controllable manner.
  • the drum a and thus the belt b lying thereon are brought to about the working temperature and the same tensioning processes, starting from the first tensioning step (sequence 1), as described in the previous paragraph, are repeated.
  • the band b is fixed on both sides of the future cut and cut with a side milling cutter t linearly moved in its own rail guide (FIG. 7).
  • the milling cut should be smoothed at both ends of the belt (Fig. 8) and the oxide layer of the belt surface should be sanded down on both sides in the usual way, each by about 10 mm.
  • the two ends of the band lie snugly against one another. After milling, the gap is slightly more than the milling cutter thickness.
  • Closing of the milling string is achieved by heating the drum and belt again to a higher temperature level and performing a further "re-tensioning" of the belt, as already described, at this temperature.
  • Endless welding is carried out using the TIG plasma process or another suitable welding process.
  • the groove a copper bar 1 provided with a welding groove m, which projects beyond the drum surface by approximately 1/10 mm (FIG. 9). If no groove has been milled, a correspondingly thin underlay strip is placed between belt b and drum a.
  • Tension flaps n press the two strip ends, which lie close together, onto the copper bar 1.
  • the welding is carried out with precisely set welding parameters and electromotor-controlled detector guide p (FIG. 9).
  • the drum radius can also be precisely maintained in the area of the weld seam (FIG. 10).
  • the surface of the welding zone is matched to the rest of the strip surface by mechanical processing, for example by grinding and subsequent polishing.
  • the drum a does not have a suitable reversible drive, it can be moved back and forth by a crank drive x for machining the weld seam area, which considerably shortens the machining time (FIG. 23).
  • the last step is trimming the tape, i.e. the excess tape edges are cut away using a cutting disc, milling cutter or turning tool and the tape edges are deburred. If the protruding tape edges do not interfere, trimming can be omitted.
  • the invention is not limited to the illustrated embodiment.
  • the drum, with drum also being understood as a wheel, the peripheral surface of which serves as a working surface, can also be rolled over the belt; instead of the projections, grooves on the side can also be used to guide the tensioning elements.
  • clamps or bonds can also be used for fastening, and screw spindles or wedges can also be used as clamping devices instead of hydraulics.
  • tensioning belts o are used, which are looped over the drum a with the metal band b and then placed under tension, whereby they transmit this tension to the band b.
  • the condition for this is that the coefficient of friction cm between the metal band b and drum a is smaller than the coefficient of friction between the tension belt and the metal band. This can be done by choosing a suitable material pairing or by increasing or avoiding linings or intermediate layers.
