2. Description of the Related Art Generally, when manufacturing a catalytic converter in which a catalyst carrier is fixed to the inner periphery of a holding cylinder via a holding material such as a non-expansion mat, first, a ring shape is formed on the outer periphery of the catalyst carrier. Attach the holding material. Next, the catalyst carrier with the holding material is inserted into the holding cylinder. The inner diameter of the holding cylinder is equal to or larger than the outer diameter of the holding material wound around the catalyst carrier,
The catalyst carrier can be easily inserted into the holding cylinder. After the insertion of the catalyst carrier, the diameter of the holding cylinder is reduced by spinning or the like. As a result, the catalyst carrier is fixed to the holding cylinder, and a catalytic converter is manufactured (see JP-A-2000-45762).

Next, the catalytic converters A, B,
A method for manufacturing C will be described. When manufacturing the catalytic converter A, first, as shown in FIG. 4, the outer diameter of the holding member 3 mounted on the outer periphery of the catalyst carrier 2 is measured. In this case, when the pressure equivalent to the pressure applied to the holding member 3 (hereinafter referred to as holding pressure) when the catalyst carrier 2 is pressed into the holding cylinder 1 is applied to the holding member 3, the outer diameter of the holding member 3 is reduced. It is desirable to measure. If the thickness when the holding pressure is applied to the holding material 3 is known, instead of measuring the outer diameter of the holding material 3 attached to the catalyst carrier 2, as shown in FIG. May be measured. This is because the outer diameter of the holding member 3 can be determined by adding twice the thickness of the holding member 3 when the holding pressure is applied to the measured value.

Next, a material for the holding cylinder 1 into which the catalyst carrier 2 on which the holding material 3 and the mesh 4 are mounted is to be press-fitted is prepared. As a material of the holding cylinder 1, a material having an inner diameter that can apply an appropriate pressure to the catalyst carrier 2 after press-fitting is used. This can be achieved by preparing a large number of materials having different inner diameters in advance and selecting one having an appropriate inner diameter from among them. As another method, as shown in FIG. 6, a material 1 'having an inner diameter smaller than the holding cylinder 1 is expanded by bulging or the like,
The material 1 'having an appropriate inner diameter can be obtained. It should be noted that one end of the raw material 1 ′ is attached to the catalyst carrier 2 from the one end.
In order to easily press-fit the material 1 'into the material 1', it is desirable to form a diameter-enlarging portion 14 whose diameter increases from the center to the end. The enlarged diameter portion 14 can be formed by flaring or the like.

Next, as shown in FIGS. 7 and 8, the catalyst carrier 2 on which the holding material 3 and the mesh 4 are mounted is press-fitted from the enlarged diameter portion 14 to the center of the material 1 '. When the catalyst carrier 2 is press-fitted, it is desirable to measure the press-fitting load, and to make the product only when the press-fitting load is within a normal range. If the press-fit load is smaller than the appropriate value, the contact pressure applied to the holding member 3 is small, and there is a possibility that the exhaust gas introduced into one end of the holding cylinder 1 may scatter the holding member 3. If it is large, the catalyst carrier may be broken by excessive pressure. Instead of measuring the press-fit load, the press-fit speed of the catalyst carrier 2 into the material 1 'may be measured. In that case, it is desirable to press-fit the catalyst carrier 2 by applying a constant force. Of course, when the press-fitting speed is measured, only products whose press-fitting speed is within the normal range are regarded as products.

Next, as shown in FIG. 9, a diffuser portion 12 and a bent portion 13 are formed at both ends of the material 1 '.
The diffuser portion 12 and the bent portion 13 can be formed by, for example, a spatula drawing method. By forming the diffuser portion 12 and the bent portion 13, the material 1 'is used as the holding cylinder 1, and the catalytic converter A is manufactured.

As described above, in the present invention, since the catalyst carrier 2 is press-fitted into the holding cylinder 1, the holding cylinder 1 does not vibrate during the press-fitting. Therefore, an excessive pressure does not act on a part of the catalyst carrier 2 when the catalyst carrier 2 is press-fitted. Moreover, since the outer diameter of the catalyst carrier 2 or the outer diameter of the holding material is measured before press-fitting and the catalyst carrier 2 is press-fitted into the holding cylinder 1 having an inner diameter suitable for the measurement, an excessive pressure acts on the catalyst carrier 2. Can be prevented beforehand. Therefore, it is possible to prevent the catalyst carrier 2 from breaking. In particular, by measuring the press-fit load or press-fit speed when press-fitting the catalyst carrier 2 into the holding cylinder 1, it is possible to more reliably prevent the catalyst carrier 2 from breaking.
