TH8466B - Method for producing honeycomb-like metal carriers - Google Patents

Abstract

The invention relates to a method for producing a metal carrier for carrying catalysts used to clean automobile exhaust gases by forming a honeycomb cross-sectional core. and inserting the resulting inner core into the outer cylinder having a diameter almost the same as that of the inside diameter outside of the spindle part The tee, which at least one end of the barrel with the outside was extended. and a piece of the inner core is inserted into the outer barrel The end surface of the inner core is pressurized to move the inner core into the outer cylinder. and the assembly is heated to cause the extended tip to shrink and regain its shape. or foil binder is wrapped around the outer circumference to form an inner core with the wrapped portion of the foil. and inserting the resulting inner core into an outer cylinder having the inner diameter almost the same as the outer diameter of the inner core part There is a characteristic that The inner core is contracted by a split die with a step section of diameter smaller than the inner diameter of the outer barrel. And the inner core is compressed into the outer cylinder to hold the inner core and the inner cylinder is pressed into the outer cylinder to hold the inner core to the outer cylinder or for metal carriers with characteristics resembling a honeycomb that is not circular Arrangement of rolled parts that are formed into round bars HM is a sheet with separate rounds. are arranged into pre-defined intervals is the middle part Inserting the ends of the flat sheet and the corrugated sheet to be folded into the flat sheet winding crevice and a corrugated sheet surrounding the outer part of the central part to form the inner core and the core wrapped the inner core into the outer cylinder To form a metal carrier that resembles a non-circular honeycomb.

Claims (6)

1. In a method for producing bee-like metals for the use of a catalyst that cleans flue gas. Where the carrier is in the form of a honeycomb core. Formed by winding a number of alternating sheets of metal loops, mattresses and plates By inserting the core into the outer cylindrical shroud having the same internal diameter as the outer diameter of the core, this improvement includes Shrinking the core to its outer diameter Which is smaller than the inner diameter of the cylindrical encapsulation. Inserting the shrunken core into the cylindrical encapsulation and releasing this shrunken core portion extends to its initial outside diameter to extend to the cylindrical encapsulation in this way. The process of shrinking the axis. This makes it possible to clean the process of inserting the core into the cylinder shroud. 2. Method according to claim 1 where the process of shrinking this axis consists of Axial retraction in a smaller diameter section of the split nozzle. And the insertion process consists of Extending the trunk encapsulation by a larger diameter section of a separate nozzle And the compression of the t-core was contracted from the small diameter section of the separate nozzle into the cylindrical encapsulation. 3. Method for claim 2 which consists of The roll of the forks wraps around the periphery of the outer part of the core to create the core part that is wrapped around the sheet binder. Before then, when the contraction Shrinking the axial portion bounded by the binder of the foil until the diameter is smaller than the inner diameter of the cylindrical shroud. And the compression of the shrinked T-core with the binder part of the sheet into the cylindrical encapsulation. To attach the bonded core of the sheet to the cylindrical encapsulation. 4. Method for claim 1 whereby the contraction procedure consists of Axial retraction with a nozzle To cause the T axis to be contracted With a diameter smaller than the inner diameter of the cylinder shroud and where the insertion procedure consists of securing the cylinder shroud with a support tool and extruding the shrunken axial portion in an axial direction. To push the core that has been bent into the external cylinder. After that Release the condensed and inserted core portion to expand its initial diameter. To hold the cylinder encapsulation 5. Method according to claim 4 which consists of The roll of the fock binder surrounds the outer periphery of the core part to form a gaflet that is wrapped around the sheet binder. Before the contraction procedure Shrinking the core part wrapped around by the binder of the foil until the diameter is smaller than the inner diameter of the cylinder shroud. And the extrusion of the shrunken core with the part wrapped around the sheet binder into the cylindrical encapsulation. To access the core part of the Ford binder and the cylindrical encapsulation. 6. Method for preparing honeycomb-like metal products According to clause 1, where this improvement consists of the coiling of the forged sheet binds to the periphery of the outer part of the core at the end of the core, the fastening of the external cylindrical encapsulation on the surface. Noun of the axis Shrinking the end of the core part containing the binder of the foil wrapped on it. Until the diameter is smaller than the diameter of the inner diameter of the cylinder envelope Inserting the retracted front end of the core into the cylinder shroud So that the binder of the Ford sheet is inside the wrap And the remainder of the core shrinkage until the diameter is smaller than the center fraction of the inner diameter of the encapsulation. Inserting the shrunken core into the shroud And the release of the contracted axis to expand to its initial diameter. To adhere to the diameter of the cylinder encapsulation in this way
