Embodiment Construction

[0018] see Figure 5 with Image 6 First, the strip-shaped nickel-based brazing material 5 is pressed on the required seam welding position with the seam welder roller 6, and the strip-shaped nickel-based brazing material 5 is positioned with a positioning device (not shown in the figure of the positioning device), The flat sheet material barrel 8 is moved by the feeding device 10 along the direction of the arrow "→" in the figure. The seam welder roller 6 installed in the seam welder 9 seams the strip-shaped nickel-based brazing material 5 on the metal carrier inner core plate sheet 4 . Finally, the flat sheet 4 of the strip-shaped nickel-based brazing material 5 that has been rolled and welded is cut to a required length with a cutter 11 . The position, quantity and width of seam welding required for the strip-shaped nickel-based brazing material 5 are determined according to the desired position, quantity and width of the brazing connection. The strip-shaped nickel-based...

Abstract

The invention discloses a solder applying method on the metal carrier flat sheets used for catalyst, which is as follow: zonal nickel-base brazing materials are respectively seam-welded on the upper surface and the lower surface of the flat sheet of the inner core of the metal carrier used for catalyst, wherein, the length direction is parallel; the seam-welded zonal nickel-base brazing materials are bound and welded on the flat sheet of the inner core of the metal carrier, thereby the arrangement of the brazing rods on the inner core of the metal carrier is ensured. The method is particularly suitable for making S-shaped metal carrier. When making the S-shaped metal carrier, the flat sheet and the corrugated sheet for seam-welding the brazing rods are cut into the given length, and then are stacked alternately and finally coiled to form the S-shaped metal carrier. The method has the advantages of high productivity, low production cost and stable quality.

Description

technical field [0001] The invention relates to a production process of a metal carrier for carrying a catalyst for purifying motor vehicle exhaust, in particular to a method for applying solder on a flat sheet of the metal carrier for the catalyst. Background technique [0002] The metal carrier for the catalyst is composed of a honeycomb inner core containing many air holes extending along the axial direction and a cylindrical or non-cylindrical shell covering the outer periphery of the honeycomb inner core. The metal carrier honeycomb core is formed by stacking corrugated sheets and flat sheets and then winding them. How to make the solder evenly and flatly distributed is one of the keys to improve the compressive strength and service life of the metal carrier. [0003] Patent CN03151202.X discloses a method for making a catalyst metal carrier with a circular cross section. Spot-weld several brazing rods on both sides of the flat sheet, and spot-weld the corrugated sheet...
