な強度を得ることができない虞があった。As described above, in a conventional metal carrier, a corrugated plate and a flat plate are wound and joined in multiple layers to form a cell through which exhaust gas and air pass. As can be seen from the formula of (1) radius × load, as the diameter of the core 5 increases as the corrugated sheet 1 and the flat plate 3 are wound, the torque applied to the center of the core 5 increases. In the method of manufacturing the carrier, when the number of turns of the corrugated sheet 1 and the flat plate 3 increases, the corrugated plate 1 is tightened due to slippage of the flat plate 3, so that the cells in the center of the core 5 are crushed. At the time of attachment or diffusion bonding, there is a possibility that a bonding failure may occur and a sufficient strength of the metal carrier may not be obtained.

It has been pointed out that there is a possibility that the joint will be deformed and defective bonding will occur during brazing or diffusion bonding. The present invention has been devised in view of such circumstances, and it is an object of the present invention to provide a method of manufacturing a metal carrier which is excellent in strength by preventing collapse of cells in the center of a core due to tight tightening.

される。(Operation) According to the method for manufacturing a metal carrier according to the present invention, after a corrugated sheet and a flat plate are wound a predetermined number of times, one valley of the corrugated sheet and a flat plate abutting on the valley are welded. , The flat plate is further wound once, and the flat plate and one peak portion of the corrugated plate abutting on the inner periphery of the flat plate are welded in the vicinity of the previous welded portion.
One valley of the corrugated sheet and a flat plate abutting on the valley are sequentially welded at a place where the corrugated sheet and the flat sheet are wound a predetermined number of times.
By winding and welding the flat plate and one peak of the corrugated plate abutting on the inner periphery in the vicinity of the previous welded portion, the flat plate having a kind of cylindrical structure is centered on the center of the core. Are formed successively at predetermined intervals, so that the flat plate does not slip during the production of the metal carrier, and the corrugated plate at the center of the core is prevented from being crushed.

同様である。The spot welding of the winding end of the corrugated sheet 1 and the flat plate 3 to the inner cylinder 15a and the welding end of the corrugated sheet 1 and the flat plate 3 to the inner cylinder 15a are the same as in the conventional example shown in FIG. Also, after the wound core 5 is press-fitted into the outer cylinder 11 of FIG. 7 and these are diffusion-bonded, a harness 15b is retrofitted into the inner cylinder 15a to form a sheathed heater 15, such as platinum or alumina. This catalyst is carried on the corrugated plate 1 and the flat plate 3 in the same manner as in the conventional example.

る。The manufacturing method according to this embodiment forms the core 5 in this manner. When the core 5 is formed in this manner, the flat plate 3 having a kind of cylindrical structure becomes the core 5. Since the cores 5 are sequentially formed around the center, the strength of the center of the core 5 is increased, and the flat plate 3 is prevented from slipping at the time of winding, so that the corrugated sheet 1 at the center of the core 5 is prevented from collapsing.

As a result, the bonding failure due to the brazing or the diffusion bonding performed thereafter is eliminated. Thus, it is possible to manufacture a metal carrier having a sufficient strength as compared with the related art. In the present embodiment, too, the spot welding spots are reduced as the diameter of the core 5 increases, so that there is an advantage that the labor of the welding operation can be reduced.
