本発明は、例えば自動車の排気ガスを浄化するために用
いられる金属触媒担体に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a metal catalyst carrier used, for example, for purifying exhaust gas from automobiles.
従来、排ガス浄化用触媒担体としては、触媒成分に対す

ラミック体は押し出し成形技術の制約から、セル隔壁の

るのであるが、セラミンク製担体と金属製収納ケースと
は熱膨張率が異なるために、特別な、熱膨張差の緩衝手
段を要するなどの不具合があった。Conventionally, extrusion molded products made of ceramic materials such as cordierite, which have excellent supporting properties for catalyst components, have been frequently used as catalyst carriers for exhaust gas purification. Due to limitations in extrusion molding technology, this type of ceramic body has a limit to the thickness of the cell partition walls, and it has been difficult to make the thickness of the cell partition walls thinner than about several tens of microns. In addition, when the obtained carrier is used as a catalyst, it is usually stored in a heat-resistant metal case, but because the thermal expansion coefficients of the ceramic carrier and the metal storage case are different, a special case is required. However, there were problems such as the need for buffering means for the difference in thermal expansion.
これに対し、耐蝕性、耐熱性を有する金属板を積層して
触媒担体として用いる、いわゆる「メタルハニカム」が

衝材が不要となる。On the other hand, a so-called "metal honeycomb" in which corrosion-resistant and heat-resistant metal plates are laminated and used as a catalyst carrier is described, for example, in JP-A-63-162045. This metal honeycomb eliminates the need for an intermediate cushioning material because the thickness of the honeycomb partition walls can be made thinner than that of a ceramic honeycomb, and the coefficient of thermal expansion is approximately the same as that of a metal storage case.

。However, in conventional metal honeycombs, corrugated plates and flat plates are alternately laminated and integrated by brazing, welding, etc., resulting in a complicated structure.In addition, if the integration is insufficient, There was a problem in that the members shifted and the telescope was deformed as if it had been stretched (scoping phenomenon).
本発明は上記問題点に鑑みてなされたものであり、平板

。In order to achieve the above object, the present invention provides a metallic catalyst carrier in which a corrugated metal base material having peaks and troughs is rolled up in a spiral cross section. A protruding part is provided on at least one of the peaks and valleys, and the protruding part is brought into contact with the other peak or valley, so that the peaks and peaks in the radial direction of the vortex in the spiral state are
Alternatively, the interval between the valleys is set to a predetermined interval.

The distance between the peaks or valleys in the radial direction of the vortices is maintained at a predetermined interval.
以下、本発明の実施例を図面に従って説明する。 Embodiments of the present invention will be described below with reference to the drawings.

る。FIG. 1 is a perspective view of a metal base material l used in a first embodiment of the present invention. 2 is a side view of FIG. 1, FIG. 3 is a plan view thereof, FIG. 4 is a sectional view taken along line AA in FIG. 3, and FIG. 5 is a sectional view taken along line BB in FIG. 3. As can be seen from these figures, the metal base material 1 is a corrugated plate having peaks 7 and troughs 9, and a claw-shaped protrusion 3 formed in the vicinity of the peaks 7 by cutting and bending. Similarly, it has a protrusion 5 formed in the shape of a claw near the trough 9 by cutting and bending. 6 to 8 are process diagrams showing the manufacturing process of the metal base material 1 used in this example. First, as shown in FIG. 6, the protrusions 3 and 5 are formed on the metal base material l by cutting and bending using a cutting and bending mold 11.13. Next, as shown in FIG. 17, the peaks 7 and valleys 9 are formed at a desired bending angle.
その後第８図に示すように、巻き芯１５に巻回、積層す

防止する効果を有している。As can be seen from FIG. 9, each peak 7 and each trough 9 is in contact with the protrusion 5 or 3 of the other winding layer, which makes the width of the layer constant and prevents the wave from forming as before. This has the effect that there is no need to use a flat plate provided for the purpose of separating the plate and the corrugated plate. In addition, in this embodiment, the protrusions 3 and 5 are provided in both the peak part 7 and the valley part 9, respectively, and the valley part 9
Another ridge 7 is fitted into the gap between the crest 7 and the protrusion 5, and another trough 9 is similarly fitted between the ridge 7 and the protrusion 3, as shown in FIG. This has the effect of preventing displacement in the direction perpendicular to the plane of the paper.

The sectional view, FIG. 14, is a sectional view taken along line D in FIG. 12. The metal base material 21 has flat convex portions 23 and concave portions 25 formed in a zigzag shape. Figure 15 shows the metal base material 21
FIG. 3 is a partially enlarged side view of a honeycomb-shaped structure formed by winding and stacking the same, as seen from the axial direction. As can be seen from FIG. 15, since the metal base material 21 has flattened convex portions 23 and concave portions 25, when it is wound and laminated, the convex portions 23 and 25 are flattened.
3 contacts the concave portion 25 of the outer layer, and the concave portion 25 contacts the convex portion 23 of the inner layer at the flat portion, so that the distance between each layer is kept constant.

The present invention also has a common point of winding and laminating as shown in FIG. 16, but in the conventional technology, as shown in FIG. A flat plate 44 is provided between the corrugated plate 42 of the inner layer.
この従来技術において平板４４を用いずに巻回、積層し

有している。In this prior art, when winding and laminating are performed without using the flat plate 44, the corrugated plates of each layer touch at the peaks or valleys, or the peaks approach each other, as shown in FIG. The intervals are not constant. On the other hand, the present invention explained in the above embodiment has the advantage that a flat plate is not necessary.
なお、上記第１の発明の実施例においては、波板を用い
