Field of the Invention The present invention relates to a metal carrier installed in an exhaust gas system for purifying exhaust gas discharged from an engine such as an internal combustion engine, and more particularly to a method for manufacturing a honeycomb body constituting the metal carrier. It is a thing.

成する。2. Description of the Related Art As a catalyst carrier installed to purify engine exhaust gas of an automobile, a metal carrier has been used more recently than a ceramic carrier.
The metal carrier is formed by stacking a flat foil made of a heat-resistant metal and a corrugated foil obtained by processing the wavy shape on top of each other, and inserting a honeycomb body formed by spirally winding the foil into an outer cylinder made of a heat-resistant metal. .

スと接触しガス成分を浄化する。The flat foil and the corrugated foil, and the honeycomb body and the outer cylinder are mainly joined by a brazing material. Such a honeycomb body carries a catalytic metal such as Pt, which comes into contact with exhaust gas and purifies gas components.

ればならない。The metal carrier installed in the exhaust gas system of an automobile appropriately comprises a honeycomb body and an outer cylinder, especially a flat foil and a corrugated foil which constitute the honeycomb body, in order to withstand vibration during operation and thermal stress in a high temperature exhaust gas environment. Must be joined so as to have rigidity.

アップになる。In order to obtain a joint with suitable strength, the flat foil and the corrugated foil must be in good contact so as to be uniform. For that purpose, it is necessary to wind the flat foil and the corrugated foil while applying tension at the time of manufacturing the honeycomb body. Conventionally, a method has been adopted in which the tip of a flat foil is hooked or wound around a core shaft and then wound around the core shaft together with a corrugated foil while applying tension to the flat foil. The inconvenience occurs that the flat foil comes off the shaft. Therefore, a method of fixing the flat foil front end portion to the core shaft by spot welding or the like is used, but the number of working steps and manufacturing equipment is increased, and the cost is increased.

いる。On the other hand, Japanese Patent Publication No. 4-63738 discloses that
It is disclosed that a corrugated foil is wound on a winding shaft by using a toothed roller, and then a flat foil is added to produce a stable honeycomb body. FIG. 4 shows the end face of the honeycomb body from which the toothed roller used as the winding shaft is removed in the central portion.

という問題がある。In this case, however, the corrugated foil can be easily wound because it follows the winding shaft, but it is difficult to wind the flat foil. In other words, it is necessary to apply tension in order to wrap it between the flat foil and the corrugated foil without any gap, but in the corrugated foil, the waves are easily deformed and the mountains collapse when the tension is applied. It is wound by applying tension. Like the method disclosed in the above publication,
When the corrugated foil is wound inside and the flat foil is wound outside, there is a problem that sufficient tension cannot be applied because the end of the flat foil is not constrained.

きる。As described above, according to the present invention, the tip of the flat foil is sandwiched between the two split winding shafts, and the corrugated foil is supplied after being wound around at least 1/4 rotation winding shaft. At this time, tension is applied to the flat foil. While it is wound, it does not come off from the winding shaft because the flat foil is wound around and fixed to the winding shaft. On the other hand, when sufficient contact pressure is required for contact between the flat foil and the corrugated foil, as in the case of diffusion bonding, high tension must be applied to the flat foil. If the flat foil is sandwiched between the winding foil and the winding is overlapped with the corrugated foil, the winding shaft rolls or the tension applied to the flat foil causes the innermost corrugated foil to be crushed and the flat foil to be wound on the winding shaft. The foil is tightly wound and the winding shaft cannot be removed. Therefore, in the present invention, the initial winding body, in which one to several windings of the flat foil-corrugated foil are wound on the winding shaft sandwiching the flat foil as described above, is supported by the clamps with the disks in contact with both end surfaces thereof. As a virtual winding shaft, the flat foil-corrugated foil can be stably wound and laminated on the virtual winding shaft in a clamped state under application of high tension to form a honeycomb body. Also, the winding shaft can be easily separated from the honeycomb body.

The flat foil is wound around a winding shaft having a slit formed in the middle and having two split pieces, by inserting the leading end portion of a flat metal foil, and rotating the winding shaft 1/4 rotation or more. After that, carry out initial winding by winding the corrugated foil between the flat foil and the winding shaft, or between the flat foil and the flat foil wound around the winding shaft, or by further winding the flat foil and corrugated foil several times. The wound and molded initial wound body has a contact surface with the end surface having substantially the same area, and is detachably supported by a winding shaft to sandwich both end surfaces of the initial wound body, and the initial wound body. It is supported by a disc-shaped clamp that rotates synchronously with the revolving body, and subsequently, while maintaining the support state in the clamp, a flat foil and a corrugated foil are spirally laminated and wound to form a cylindrical honeycomb body, and A method for manufacturing a honeycomb structure on a metal carrier, which comprises removing a winding shaft.
