Definitions

  • the invention relates to a method and an apparatus for producing a catalyst having a monolith having a polygonal cross-section.
  • Polygon is to be understood here as the shape of a polygon whose corners are rounded.
  • Automotive catalytic converters consist of a central, rod-shaped, ceramic honeycomb body, called Monolith, which is traversed in the longitudinal direction of many fine channels.
  • the monolith is surrounded by the interposition of a so-called Blähmatte of mineral pulp from a jacket plate, in particular stainless steel.
  • the jacket plate must be very tight over its entire circumference, so that especially during operation of the motor vehicle, the shock-sensitive material of the monolith is not damaged, no annoying rattling noises occur and the seal between the monolith and the jacket plate is ensured.
  • the jacket sheet is cold at rest, however, very hot in the operating condition. As a result, the jacket sheet is subject to some expansion or shrinkage in the peripheral region.
  • the invention has for its object to provide a method in which the above technical requirements are met even in a catalyst having a rounded polygonal shape in cross section. Furthermore, an apparatus for carrying out this method should be proposed.
  • the invention enables the formation of the catalyst with a cross section which differs substantially from the ideal circular shape. Particularly suitable are rounded polygons with a large radius, since the monoliths can also be produced well in such a form. There is only a longitudinal seam for connecting the jacket plate, which can be very economically produced from separated from coil material boards. If an overlap of the edge areas to be joined is provided, even larger dimensional tolerances of the monolith or the board can be compensated for without any additional effort in the overlapping area. The edge areas of the shroud can then be in the overlap area with more or less overlap, e.g. under protective gas, to be welded. On the other hand, if the marginal areas lie exactly in shock to impact, additional welding material can be applied to the joint to make the connection.
  • the jacket sheet is preformed at least almost to its final shape before its edge regions are brought into their connecting position and connected to each other.
  • This preforming of the jacket plate can be carried out in an upstream, separate bending device.
  • the preformed jacket sheet is clamped together with the Blähmatte and the polygonal monoliths in a jig so that the jacket sheet has now completely its intended end shape and the edge regions are in the connecting position, whereupon the edge regions are finally connected.
  • An apparatus for carrying out the method according to the invention provides that a clamping device surrounds the jacket plate and comprises over its circumference at least two profile pieces which are connected to each other via at least one flexible tension member and are movable relative to one another via a power-operated device so that the circumference of the clamping device and so that the shroud is reduced, but it remains free between the profile pieces access to the edge regions to be joined together.
  • the flexible tension member can be designed as desired. It can be at least partially z. As a rope, a chain or the like. If it is designed as a chain consisting of balls, rollers or eyelets, then the pressure piece can be said to act as a reinforced chain link, e.g. be shaped as a thicker ball or roller. Otherwise, the flexible tension member with the aid of a corresponding training also be guided over or through the arbitrarily shaped pressure piece, while maintaining its shape. If the pressure piece has a bulge toward the jacket sheet, a basically polygonal, but also a local, at least slightly concave formation of the jacket sheet can be ensured by gapless radial tension.
  • the force applied to the tension member power-operated device may comprise tie rods, which are for example applied approximately tangentially to the jacket plate and alternately in the opposite direction.
  • the device may include power operated toggle.
  • the power-operated device may be mechanically, pneumatically or hydraulically actuated and controllable.
  • the bending and / or clamping device may have at least one support for the tension member and / or for a pressure piece on the edge regions, and thus the weld, opposite side. Then, the shape of the support can be adapted to the shape of the tension member and / or the pressure piece.
  • the profile pieces and / or the pressure pieces can be adapted in cross section to the final shape of the jacket plate.
  • the device according to the invention ensures defined holding forces of the monolith to the jacket plate in a variety of polygonal, rounded cross sections. It thus allows a process-safe production of the catalyst with the circular shape also significantly deviating cross-section, which may have even slightly concave curved peripheral regions in the extreme case. Thus, a high adaptability to the available space is achieved: Due to the very flexible cross-sectional design of the given space can be maximally and thus optimally utilized, which is particularly advantageous in the automotive industry
  • FIG. 1 shows the side view of a preassembled, in cross-section approximately triovalen catalyst with preformed and clamped in a jig, ready for welding jacket sheet.
  • FIG. 2 shows the top view of the jig after FIG. 1 ,
  • the catalyst 1 consists in Fig.1 initially from the central, rod-shaped, in cross-section triovale ceramic honeycomb body, the monolith 2 is called.
  • the monolith 2 is surrounded by a so-called Blähmatte 3 of mineral pulp and a jacket plate 4 under bias.
  • the jacket sheet consists of a Chromium-nickel steel, is cut from Cilmaterial to a board and was preformed in a bending device, not shown, in a nearly closed mold.
  • the preformed jacket plate 4 is formed in mirror image in cross-section and includes differently curved, part-circular sections 5 to 11.
  • the jacket plate 4 further comprises two overlapping edge portions 12 and 13 which extend in the longitudinal direction of the monolith 2 and are inseparably connected to each other.
  • the tensioning device 14 comprises two profile pieces 15 and 16, which are connected to each other via a flexible, designed as a roller chain 17 tension member.
  • the profile pieces 15 and 16 and the roller chain 17 wrap around the jacket plate 4 almost entirely leave only a gap 18 between the profile pieces 15 and 16 free. In this space 18, the edge regions 12 and 13 are superimposed, so that a welding seam can be produced with a welding torch 19 under inert gas.
  • the profile piece 15 includes and presses on the portion 5 of the jacket plate 4.
  • the roller chain 17 is articulated, which consists of a first chain portion 20 which presses on the section 7.
  • the chain section 20 is articulated to a pressure piece 21 which presses on the section 9.
  • a second chain portion 22 is articulated, which presses on the portion 11.
  • a second pressure piece 23 is articulated, which presses on the portion 10.
  • a third chain section 24 is articulated, which presses on the section 8.
  • the third chain section 24 is finally articulated to the profile piece 16, which presses on the section 6.
  • jacket plate 4 is applied radially over all sections 5 to 11 of its circumference and thus pressed together with the Blähmatte 3 against the monoliths 2.
  • the pressing takes place uniformly, since the flexible chain sections 20, 22 and 24 evenly adapted to the relatively strongly curved portions 7, 11 and 8 of the jacket plate 4. Furthermore, the profile pieces 15 and 16 to the bend of the relatively weakly curved portions 5 and 6, the plungers 21 and 23 to the Bending the also relatively weakly curved sections 9 and 10 adapted, to the desired final shape of these sections.
  • a support 25 is provided, on which the chain portion 22 can be supported, wherein the support 25 is adapted with its support surface 26 of the bend of the chain portion 22 and thus indirectly the bending of the section 11.
  • the tensioning device 14 further comprises a power-operated device in the form of tie rods 27 and 28.
  • the tie rods 27 and 28 are alternately hinged to the profile pieces 15 and 16, see also FIG. 2 , And are applied approximately tangentially to the jacket plate 4 by forces F. These forces F ensure the position of all components involved until the weld at the edge regions 12 and 13 is completed.
  • the tie rods 27 and 28 may also be operated via toggle.
  • the required forces can be generated mechanically, pneumatically or hydraulically.
  • the invention has been described by way of example with reference to a so-called trioval cross section.
  • the method according to the invention can be applied to a multiplicity of rounded, polygonal cross sections by expertly adapting the device.
