製品の歩留まりを下げる結果となっていた。[Prior Art] A metal carrier is a layer of alternating flat and corrugated metal foils formed into a honeycomb structure, and when press-fitting it into a metal outer cylinder, the outermost flat plate is Because the plate is thin, the frictional force on the inner surface of the metal outer cylinder acts as resistance, making it difficult to enter. Conventionally, the honeycomb body was press-fitted into the outer cylinder by pushing from the top of the honeycomb body using only the press-fitting head, but when the amount of press-fitting the honeycomb body into the outer cylinder became large, the flat foil would pop out from the end face of the outer cylinder.
This resulted in a decrease in product yield.

In order to create a joint with as little space as possible between the honeycomb body and the outer cylinder that holds it, the honeycomb body is housed in an outer cylinder tube that is larger than the finished product size in advance, and a part of the honeycomb body is A method of integrally drawing the material by squeezing it with a drawing tool is disclosed. However, in this method, the surface of the outer cylinder is drawn by being directly rubbed with a drawing tool, which may cause scratches or burn-in scratches, which may reduce the product value.

A method of press-fitting a metal honeycomb body for exhaust gas purification. That is, the present invention suppresses the occurrence of deviation in the press-fitting direction of the flat plate and corrugated plate by clamping the head of the honeycomb body, and the flat plate press-fits against the inner surface of the metal outer cylinder, thereby producing metal with stable quality. This is to obtain a carrier.

The honeycomb body 3 is slightly press-fitted using the press-fitting head 2. Next, the head of the honeycomb body 3 is clamped and restrained by the clamp jig 1. At this time, the upper surface of the honeycomb body 3 is aligned with the lower surface of the press-fitting head 2. Next, as shown in FIG. 1(b), force is applied to the press-fitting head 2 to press-fit the honeycomb body 3 into the metal outer cylinder 4, and the press-fitting head 2 is pressed just before the clamp jig 1 and the metal outer cylinder 4 come into contact. Stop. At this time, since the head of the honeycomb body 3 is restrained by the clamp jig 1, the outermost flat plate of the honeycomb body 3 is press-fitted into the metal outer cylinder 4 without protruding from it. Next, as shown in FIG. 1(c), the clamp jig 1 that was restraining the head of the honeycomb body 3 is released, and the head of the honeycomb body 3 is press-fitted using only the press-fitting head 2. After press-fitting, the honeycomb body 3 is press-fitted into the metal outer cylinder 4 with its upper and lower end surfaces neatly aligned, as shown in FIG. 1(d).
