Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device for carrying it out.
  • carrier bodies for catalytic reactors for exhaust gas purification by winding from two metal strips, one of which is corrugated and the other is designed as a smooth strip.
  • the smooth metal strip is wound directly adjacent to the corrugated strip, so that it prevents adjacent layers of corrugated strips from slipping into one another.
  • carrier bodies by winding only a single strip of corresponding cross-sectional shape, in which, due to the cross-section of the corrugations, slipping of adjacent layers is avoided.
  • Another disadvantage is the thermal stresses that occur during operation, which occur due to the different temperatures in the carrier body and on the jacket sleeve and can lead to an undesired detachment of the carrier body from the jacket sleeve.
  • the invention is therefore based on the object of creating a method of the type mentioned in which, while maintaining the known winding technology, a support body which is uniformly flexible in the radial direction can be created, which can be connected in a simple manner to a jacket sleeve and also reduces the risk, that this connection is affected by thermal expansion.
  • both cylindrical, elliptical or oval cross-section carrier bodies can be produced according to the features of claims 2, 3 and 4.
  • the new process can also be carried out in various ways.
  • the stack of metal strips is not formed in a block form with end edges aligned with one another, but if a parallelepiped-shaped stack is formed by staggered joining of the end ends of the individual metal strips, each of the same length, which stack then can wind up that the connection points of the individual tapes to the adjacent tape are inward and thereby additionally secured during winding. This also creates a multi-course, spiral support body.
  • a new device by carrying out the winding method of the invention according to the features of claim 12, however, provides a winding core with at least two drivers provided on its circumference, to which the ends of the metal strips supplied by a feed arrangement can be fastened.
  • the drivers can be designed as pins projecting axially from a turntable and retractable axially into the disk, around which the ends can be bent for fastening. After winding, these pins can be pulled axially out of the carrier body, as is known per se (DE-OS 35 32 408) for other winding processes.
  • the drivers are parts of a winding core which can be displaced axially to the winding axis and which is provided with fastening slots on the circumference, which are easily connected by clamping surfaces of a winding core and by resilient flaps assigned to them Form of axially projecting from a sleeve tongues can be formed.
  • a characteristic, multi-course, spirally wound carrier body is formed, which is characterized by a large number of independently independent spiral straps extending from a central area and with their free ends lying on the outside of the jacket.
  • Such a carrier body has the advantageous features of good radial extensibility described at the outset.
  • the area (5d) can be pressed together before the stack (13) is clamped in, whereby to facilitate the compression and to facilitate a good deflection of the strips in the area (5d) during the subsequent winding, lateral slits to form the ends ( 5a, 5a ') of the tapes (5 and 5') can be provided.
  • the area (5d) can then, for example, be inserted axially into the gap (27) between two prongs (28 and 28a) of a fork-shaped part (29) until an edge of the stack (13) on the rear pane part of the part (29) is present.
  • the support body can then be formed by rotation in the direction of the arrow (32) of the part (29) about the winding axis (9).
  • Damage to the flow channels between the individual layers (5 and 6) can largely be avoided in the manufacture of the region (5d) by the shape of the crimping tool and by the shape of the prongs (28 and 28a).
  • the fork-shaped tines (28 and 28a) are pulled axially out of the carrier body after the body has been wound up. They can be dimensioned correspondingly small in order to avoid an undesirable formation of cavities in the center of the carrier body.
  • the front end (7a) is made up of a plurality of bands (7), each of which is formed from a corrugated band and a smooth band are clamped on a rotating winding body (19) in cylindrical shape, which is later pulled out axially after the manufacture of the carrier body in the form shown in FIG. 9.
  • the support body (10) can be deformed by pressure in the direction of the arrows (33) in a manner known per se to an oval and elliptical support body, as it is with (34) in its Contour is indicated schematically. In such a process, which is known per se, the initially cylindrical cavity (8) is compressed.
  • a further spirally wound cylindrical support body (11) in the initially sleeve-shaped support body (10) of FIG. 9. This can be done either by axially pressing the carrier body (11) into the cavity. It is also possible to first wrap the carrier body (11) up to a certain diameter in a known manner and then to wrap more metal strips between the respective outer layers of this carrier body, which serves as the winding core.
  • a winding core (19) is provided which is rotatable about the winding axis (9) in the direction of the arrow (32) and which is approximately cylindrical, but with its circumference roughened or even corrugated clamping surfaces (26) is provided which, together with tongues (22) projecting axially from a sleeve (20), form a plurality of clamping slots (25) distributed uniformly over the circumference.
  • the end faces (7a) of a plurality of metal strips (7) can be inserted into these clamping slots, each of which consists of a corrugated strip (7d) and a smooth strip (7c) in the exemplary embodiment.
  • This process can also be carried out by feeding these end faces (7a) tangentially to the stationary winding core, to the extent that they lie approximately on the clamping surfaces (26).
  • the sleeve (20) can then be pushed axially over the winding core and over the front ends.
  • the individual metal strips (7) are guided tangentially to the winding body (19). This could be done, for example, by unwinding supply rolls, the axes of which are arranged parallel to the winding axis (9) and which are provided concentrically around the winding core (19) at a sufficient distance. Corresponding cutting devices for cutting the individual strips (7) to length could also be arranged.
  • the axes of the twelve supply rolls to be arranged in the exemplary embodiment and the winding axis (9) could be arranged vertically on a base frame or horizontally on a corresponding guide wall.
  • carrier bodies according to FIG. 9 or according to FIG. 10 can be produced.
  • Fig. 11 shows a possibility of feeding several tapes, which are each stored in the shafts of a feed magazine divided by partitions (30) so that their ends (7a) converge in the region of a winding body (12 ').
  • a on a lever (36) pivotally arranged roller (37), which is under the force of a compression spring (38), ensures when the metal strips (7) rotate about the winding axis (9) in the direction of the arrow (32) that the bundle of metal strips (7), which are initially introduced with their end faces (7a) at least partially into a slot of the winding body (12 '), are always pressed firmly against the spirally wound carrier body during the winding process.
  • FIGS. 12 and 13 Another very advantageous possibility of producing the new carrier body is indicated in FIGS. 12 and 13.
  • a stack (14) is first formed from a plurality of metal strips (15, 16, 17 and 18) in such a way that the end faces (15a, 16a, 17a, 18a, etc.) of the individual layers of the metal strips lying one on top of the other -
  • the end faces (15a, 16a, 17a, 18a, etc.) of the individual layers of the metal strips lying one on top of the other - which, of course, can each consist of a smooth band and a corrugated band - are each offset by approximately the same amount in the longitudinal direction of the bands, so that a stack (14) of parallelepiped form is formed.
  • This stack is then, as shown in FIG.
  • FIGS. 14 to 16 show a possibility in which the end faces of a plurality of bands have not to be attached beforehand to form a stack, as in FIG. 12.
  • a first band ie a pair of bands
  • a winding body (12 ') which consists of a corrugated and a smooth band.
  • This is continued with several tapes in succession, so that, as shown in Fig.
  • a winding device (23) is provided here, which can consist, for example, of a rotating disk which is equipped with axially projecting pins (24) which can be withdrawn axially.
  • a plurality of metal bands (39) are fastened with their end faces one behind the other on a base band (7), for example by dots.
  • This end band (7) is fastened with its front end (7a) centrally in the slot of a winding axis (9), but is guided over the circumference of the pins (24) which rotate with the disk (23) around the winding axis.
  • an approximately cylindrical body can also be formed, as shown in FIG.
  • a multi-start wound carrier body is formed, in which the ends (7b) of a large number of bands lie freely outside, which can be seen particularly well from FIG. 18.
