れている。2. Description of the Related Art As a metal carrier for purifying exhaust gas, various types of honeycomb bodies in which flat bodies made of a heat-resistant metal and corrugated sheets are alternately stacked and stored in an outer cylinder made of a heat-resistant metal have been developed, and some of them have already been put into practical use. Further, a tandem-type metal carrier has been proposed in which a plurality of honeycomb bodies are housed in series in an outer cylinder so as to improve the purification efficiency of the metal carrier.

く実用的でない。However, in such a method of manufacturing a tandem-type metal carrier, a punch having a diameter larger than the outer diameter of the honeycomb body is used to store the honeycomb body in an outer cylinder like a single-type metal carrier. I couldn't. That is, since the honeycomb body other than the one located at the end needs to be inserted deeply to a predetermined position inside the outer cylinder, a press-fitting punch having an outer diameter smaller than the inner diameter of the outer cylinder must be used. As a result, at the time of press fitting, the outermost flat plate portion of the honeycomb body does not directly receive the pressing force of the punch, and the unpressed flat plate portion is displaced due to surface friction with the inner surface of the outer cylinder. This may cause the entire honeycomb body to be unable to be inserted to a predetermined position, or may cause the flat plate portion to protrude outward from the end of the outer cylinder, etc., and efficiently produce a tandem-type metal carrier as specified. There was a problem that it could not be produced. As a method for preventing the above-mentioned displacement, welding a flat plate and a corrugated plate may be considered, but welding the entire periphery of the honeycomb body is not practical because of a large work load.

法に従って行うことができるものである。Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the manufacturing process of the present invention.
In the present invention, first, a honeycomb body 1 (see FIG. 2) in which flat plates 1a and corrugated plates 1b are alternately stacked is formed by winding. next,
After the binder impregnated in the sponge 11 is sucked up by utilizing the capillary phenomenon, the brazing material 2 is sprinkled from the sieve 12 to supply and attach the brazing material 2 to the binder portion of the honeycomb body 1. The above steps are the same as the conventional steps, and can be carried out according to a conventional method without using any special apparatus or the like.

ことが可能になる。Next, in the present invention, the obtained honeycomb body 1 is transferred into a dryer 13 to dry the binder, and the flat plate 1a and the corrugated plate 1b are displaced in the press-fitting process described later by the drying process. Glue so that it does not occur. This binder is originally applied for the purpose of adhering the brazing material 2, and in an undried state, it is in a flowing state and cannot join the flat plate 1a and the corrugated plate 1b.
Through the drying step, both can be firmly bonded.

I do. The punch 14 has an outer diameter slightly smaller than the inner diameter of the outer cylinder 3. At this time, since the honeycomb body 1 is in a state of being firmly adhered to the entire circumference by the binder, a positional shift occurs even though the outermost flat plate portion of the honeycomb body does not directly receive the pressing force of the punch. Thus, it can be surely inserted to a predetermined position in the cylindrical body 3 without being inserted.

As shown in the drawing, prior to the press-fitting step, an outer peripheral surface of the honeycomb body 1 is provided with an adhesive foil braze 4 for bonding to the inner peripheral surface of the cylindrical body 3 or a brazing filler metal for bonding to the outer cylindrical body. It can be applied beforehand. Finally, the obtained honeycomb body 1 is transferred to a heater (not shown), and is heated to a temperature equal to or higher than the melting point of the brazing material, between the flat plate 1a and the corrugated plate 1b, and between the outer peripheral surface of the honeycomb body 1 and the outer cylinder 3. A tandem metal carrier is obtained by brazing the inner peripheral surface firmly.
