Definitions

  • the invention relates to a method for producing profile sealing rings, in particular in a C-, V-, or U-shape.
  • Profile sealing rings are widely used as a component of seal arrangements, in junction connections of exhaust gas-carrying lines, for example, for connections of lines to catalytic converters or cylinder heads of internal combustion engines, or for other components which carry hot gas, such as are generally found in power plant engineering. Due to the high exhaust gas temperatures which occur, the respective profile sealing ring is generally a metal component with a small wall thickness, the ring body conventionally having a profiled cross-sectional shape, for example in the form of a C-, U-, or V-profile.
  • the object of the invention is to make available a method which enables especially efficient production.
  • a band-shaped carrier part is formed by means of forming rolls such that not only is a profile strand of predetermined cross-sectional shape formed, i.e., with a C-, V-, or U-shaped cross section, but that the profile strand, after forming, is curved in the shape of an arc or spiral.
  • the process of profiling thus also includes the formation of the curvature of the strand into the desired ring shape, so that a separate bending process for ring formation is eliminated.
  • the method according to the invention therefore enables especially economical production of profile sealing rings at a high production rate.
  • the method can be carried out especially advantageously such that the profile strand is formed from the carrier part which moves in the lengthwise direction in several forming stages, the forming rolls which form the last forming singe on the facing surfaces of the profile strands causing varied friction and/or deformation in order to produce the arc-shaped or spiral curvature of the profile strand which emerges from this forming stage.
  • the flat carrier part is supplied by means of conveyor rollers to the first forming stage, in which the first forming roll with a convexly raised jacket part and an opposite second forming roll with a concavely depressed jacket part shape the carrier part into the preformed profile strand.
  • the arrangement is such that at least one forming roll of the two forming stages can be adjusted both in the working direction and also transversely to the working direction.
  • a different material thickness can be implemented in the preformed profile strand in different wall regions of the profile shape.
  • a greater wall thickness than on the lateral legs can be formed; this leads to optimum strength and elasticity conditions for the finished profile sealing ring.
  • the preformed profile strand of the last forming stage emerging from the first forming stage is supplied by way of guide rollers which can be adjusted transversely to the working direction.
  • the last forming stage which has a third forming roll with a convexly raised jacket part and a fourth forming roll with a concavely depressed jacket part, it is possible to proceed such that not only the final profile shape is obtained, but also that by adjusting the peripheral velocities and the forming pressure in the last forming stage the arc-shaped or spiral curvature of the emerging profile strand is formed.
  • One especially important advantage of the method according to the invention consists in that it is equally well-suited for production of profile sealing rings in which the profile opening is on the outside of the ring, as well as for profile sealing rings whose profile is opened into the interior of the ring.
  • FIG. 1 shows a highly schematically simplified representation of a device for carrying out one exemplary embodiment of the method according to the invention
  • FIG. 2 shows a broken away and a highly schematically simplified cross section of the device from FIG. 1 , according to the intersection line as indicated with II-II in FIG. 1 , and
  • FIG. 3 shows a highly schematically simplified top view of the device from FIG. 1 .
  • the carrier part 2 is routed in the form of a flat steel band by feed rollers 4 through a first forming stage 6 and a second forming stage 8 , the carrier part 2 being held in the middle by lateral guide rollers 10 and 12 .
  • the carrier part 2 is formed by means of a first forming roll 14 and a second forming roll 16 which interacts with it into a preformed profile strand 18 from which the final profile of the finished profile strand 24 emerging from the device is formed in the second forming stage 8 by means of a third forming roll 20 and a fourth forming roll 22 which interacts with it.
  • the guide rollers 10 and 12 can be positioned on carriers 26 transversely to the feed direction.
  • the first forming roll 14 with the convexly raised jacket part 28 acts on the supplied carrier part 2 in the middle, see FIG. 2
  • the second forming roll 16 which is the lower one in FIGS. 1 and 2
  • the concavely depressed jacket part 30 deforms the carrier part 2 laterally toward the top in order to impart a cross-sectional shape in the form of a flat, widely opened C to the preformed profile strand 18 emerging from the first forming stage 6 .
  • the concavely depressed jacket part 34 of the fourth forming roll 22 is made much differently from the concavely depressed jacket part 30 of the second forming roll 16 .
  • the jacket part 34 of the forming roll 22 is made in the form of a narrower and more deeply machined depression, compared to the jacket part 30 of the forming roll 16 . In this way a profile shape is imparted to the finished profile strand 24 , as is schematically indicated in FIG. 1 at 36 .
  • the second forming roll 16 can be positioned as indicated with the double arrow 38 in the direction to the upper forming roll 14 in order to reduce the size of the roll gap, and according to the double arrow 40 , along the working direction.
  • the fourth forming roll 22 can be positioned accordingly in the direction to the pertinent forming roll 20 and along the working direction.
  • the peripheral velocities of the forming rolls, at least the forming rolls 20 and 22 of the second forming stage 8 can be adjusted independently of one another.
  • the forming in the second forming stage 8 can take place especially advantageously such that the material of the profile strand 18 is less stretched on the profile base than on the profile sides. This can be brought about by stronger friction in the rolling process taking effect on the profile sides by the shape and dimensioning of the interacting jacket parts of the forming rolls 20 and 22 , for example, by the depressed jacket part 34 being narrowed in the external region, so that the profile strand 24 in the outer region is more heavily stretched than in the profile base. In this way the finished profile strand 24 , relative to the curvature shown in FIG. 1 with the solid line, emerges to the top with a curvature pointed downward from the second forming stage 8 , as is shown in FIG. 1 with the broken line. As is indicated in FIG. 1 at 36 , in both instances the profile is thus opened toward different sides.
  • the invention thus makes it possible to easily produce profile sealing rings with a profile that is open in the desired direction.
  • profile shapes other than the illustrated C-shape can be implemented, and profile shapes can also be produced in which the side walls of the profile can be irregularly arced.
  • contouring can be impressed on the outer sides or inner sides. The production process can take place continuously by the carrier part 2 being withdrawn as an endless sheet metal strip from a supply and routed through the forming stages 6 , 8 with the same working direction.
  • defined lengths of the carrier part 2 can be moved by means of a linear advance device in repeated back-and-forth motion through the forming stages 6 and 8 in order to form the finished profile strand 24 in several roll steps, optionally with altered positioning of the forming rolls, especially of the rolls 16 and 22 .
  • the carrier part 2 is moved as a blank in a rocking process, i.e., by motion of the blank back-and-forth through the corresponding roll pair preferably into a closed ring shape.
  • the blank at the start of the rolling process has a finite length which includes the required peripheral length of the ring.
  • the blank is rolled into the round shape by the rocking motion of the blank in the lengthwise direction of the strip which is stretched during the forming process.
  • the several rocking processes required for this purpose preferably are carried out continuously and therefore in succession in the manner of a multistep process up to final production. Then the ring is removed from the forming device, and on the end side it is brought, for example by a welding process, into the ring shape which remains closed.
