Description
本発明は、自動車等の内燃機関から排出される排気ガスを浄化するメタルハニカム担体の製造方法に関する。 The present invention relates to a method for manufacturing a metal honeycomb carrier that purifies exhaust gas discharged from an internal combustion engine such as an automobile.
自動車等の内燃機関を備えた車両には、排気ガス中に含まれる有害成分を除去するための触媒装置としてメタルハニカム担体が用いられている。このメタルハニカム担体は平板と波板とを重ね合わせて巻回すことによって製造され、断面ハニカム状をしたメタルハニカムコア体と、このメタルハニカムコア体を収納する金属製の外筒とによって構成されている。 In a vehicle equipped with an internal combustion engine such as an automobile, a metal honeycomb carrier is used as a catalyst device for removing harmful components contained in exhaust gas. This metal honeycomb carrier is manufactured by overlapping and winding a flat plate and a corrugated plate, and is constituted by a metal honeycomb core body having a honeycomb shape in cross section and a metal outer cylinder housing the metal honeycomb core body. Yes.
従来、メタルハニカムコア体の製造方法としては、波板と平板の先端部を重ね合わせて巻取軸に挾み込み、この巻取軸を回転させることによって渦巻状に巻回してハニカム状としていた（特許文献１参照）。
しかしながら、上述した従来の製造方法では、巻き回したときの最終端において、最後の周に巻かれた波板が段差となってしまい、このまま外筒に圧入してしまうと、この段差によって集中的な応力が作用して波板が変形してしまう。したがって、この変形によってコーティング後の余剰触媒フィレットが増え、通気抵抗が増加してしまうという問題点があった。 However, in the above-described conventional manufacturing method, the corrugated sheet wound around the last circumference becomes a step at the final end when it is wound, and if it is press-fitted into the outer cylinder as it is, the step is concentrated. The corrugated sheet is deformed due to excessive stress. Therefore, there is a problem that the excess catalyst fillet after coating increases due to this deformation, and the ventilation resistance increases.
また、触媒コーティング後にガスが接触する波板の単位体積当たりの表面積が減少してしまうという問題点もあった。 In addition, there is a problem in that the surface area per unit volume of the corrugated plate in contact with the gas after catalyst coating is reduced.
本発明の目的は、平板と波板とを巻回してコアを製造するときの最終端において波板による段差をなくし、コアを外筒へ圧入した後においても波板に変形が生じることのないメタルハニカム担体の製造方法を提供することにある。 The object of the present invention is to eliminate the step due to the corrugated plate at the final end when the core is manufactured by winding the flat plate and the corrugated plate, and the corrugated plate is not deformed even after the core is press-fitted into the outer cylinder. The object is to provide a method for manufacturing a metal honeycomb carrier.
上述した課題を解決するために、請求項１に記載のメタルハニカム担体の製造方法では、金属製の平板と波板とを重ね合わせて巻回すことによってメタルハニカム担体を製造するメタルハニカム担体の製造方法であって、前記平板と前記波板とを重ね合わせて巻回していき、最終周の巻回しでは、前記平板の巻回しを前記波板の巻回しよりも先に終了し、前記波板の巻回しは最終周の波板と最終周の前の周に巻かれた波板とが重なり合う地点まで行なうことを特徴とする。 In order to solve the above-described problem, in the method for manufacturing a metal honeycomb carrier according to claim 1, the metal honeycomb carrier is manufactured by manufacturing a metal honeycomb carrier by winding a metal flat plate and a corrugated plate on each other. In the method, the flat plate and the corrugated plate are overlapped and wound, and in the final winding, the winding of the flat plate is finished before the corrugated plate is wound. The winding of is performed up to a point where the corrugated sheet on the final circumference and the corrugated sheet wound on the circumference before the final circumference overlap.
請求項１のメタルハニカム担体の製造方法によれば、最終周の巻き回しにおいて平板の巻き回しを波板の巻き回しよりも先に終了させ、波板の巻き回しは最終周の波板と最終周の前の周に巻かれた波板とが重なり合う地点まで行なうようにしたので、巻き回したときの最終端において波板による段差をなくすことができ、外筒へ圧入した後においても波板に変形のないメタルハニカム担体を製造することができる。 According to the manufacturing method of the metal honeycomb carrier of claim 1, the winding of the flat plate is finished before the winding of the corrugated sheet in the final winding, and the winding of the corrugated sheet is the final winding of the corrugated sheet and the final winding. Since it was done to the point where the corrugated sheet wound on the circumference before the circumference overlaps, the step due to the corrugated sheet can be eliminated at the final end when wound, and the corrugated sheet even after being pressed into the outer cylinder A metal honeycomb carrier without deformation can be produced.
これによって、コーティング後の余剰触媒フィレットを削減して通気抵抗を低減することができるとともに、触媒コーティング後にガスが接触する波板の単位体積当たりの表面積を減少させることがないので、浄化性能を向上させることができる。 As a result, excess catalyst fillet after coating can be reduced to reduce ventilation resistance, and the surface area per unit volume of the corrugated plate with which the gas contacts after catalyst coating will not be reduced, improving purification performance. Can be made.
以下、本発明を実施するための最良の形態を図面に基づいて説明する。図１は本実施形態に係るメタルハニカム担体の製造方法の説明図、図２は本実施形態の製造方法によって製造されたメタルハニカム担体の斜視図である。 Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of a method for manufacturing a metal honeycomb carrier according to this embodiment, and FIG. 2 is a perspective view of the metal honeycomb carrier manufactured by the manufacturing method of this embodiment.
本実施形態に係るメタルハニカム担体の製造方法は、図１に示すように、金属製の薄板から成る帯状の波板１と平板２とを、巻き上げ機の芯棒に挟み込んで交互に重ね合わせ、これらを渦巻き状に巻回して断面円形状でハニカム構造を有するコア３を形成する。次いで、このコア３の外周にロウ箔材を巻回して、これらを図２に示すように、金属製の外筒４内に圧入して真空状態で加熱することにより、波板１と平板２とを拡散接合すると共に、外筒４とコア３をロウ付け接合してメタルハニカム担体５を製造する。 As shown in FIG. 1, the manufacturing method of the metal honeycomb carrier according to the present embodiment, the strip-like corrugated plate 1 and the flat plate 2 made of a thin metal plate are sandwiched between core rods of a hoisting machine, and alternately overlapped. These are spirally wound to form the core 3 having a circular cross section and a honeycomb structure. Then, a brazing foil material is wound around the outer periphery of the core 3, and these are pressed into a metal outer cylinder 4 and heated in a vacuum state as shown in FIG. And the outer cylinder 4 and the core 3 are brazed and joined to manufacture the metal honeycomb carrier 5.
ここで、図２の領域Ａの拡大図を図３及び図４に示す。まず、図３に基づいて本実施形態に係るメタルハニカム担体の製造方法による最終周の巻回しについて説明する。図３に示すように、最終周の巻回しでは平板２の巻回しをｅ地点において終了するようにしている。すなわち、平板２の巻回しを波板１の巻回しよりも先に終了させている。 Here, enlarged views of the region A in FIG. 2 are shown in FIGS. First, winding of the final circumference by the method for manufacturing the metal honeycomb carrier according to the present embodiment will be described with reference to FIG. As shown in FIG. 3, the winding of the flat plate 2 is finished at the point e in the final winding. That is, the winding of the flat plate 2 is finished before the winding of the corrugated plate 1.
一方、波板１の巻回しはその後も続けられ、最終周の波板１ａと最終周の前の周に巻かれた波板１ｂとが重なり始め、最終的に波板１ａと波板１ｂとが完全に重なり合う地点ｆまで巻き回しを続ける。そして、地点ｆで波板１ａと波板１ｂとを重ね合わせて波板１の巻回しを完了する。その後は、巻回した波板１が崩れないようにスポット溶接を行なう。 On the other hand, the winding of the corrugated sheet 1 is continued thereafter, and the corrugated sheet 1a on the final circumference and the corrugated sheet 1b wound on the circumference before the final circumference begin to overlap, and finally the corrugated sheet 1a and the corrugated sheet 1b Continue to wind to the point f where completely overlaps. Then, the corrugated sheet 1a and the corrugated sheet 1b are overlapped at the point f to complete the winding of the corrugated sheet 1. Thereafter, spot welding is performed so that the wound corrugated sheet 1 does not collapse.
次に、巻回しの完了したコア３を外筒４へ圧入する際に巻回した波板１が脱落することがないように、図４に示すように平板６を数周巻付けて強度を持たせてから外筒４へコア３を圧入してメタルハニカム担体５が完成し、本実施形態のメタルハニカム担体の製造方法を終了する。 Next, the flat plate 6 is wound several times as shown in FIG. 4 so that the wound corrugated plate 1 does not fall off when the wound core 3 is press-fitted into the outer cylinder 4. Then, the core 3 is press-fitted into the outer cylinder 4 to complete the metal honeycomb carrier 5, and the method for manufacturing the metal honeycomb carrier of the present embodiment is completed.
このように、本実施形態のメタルハニカム担体の製造方法では、最終周の巻回しにおいて平板２の巻回しを波板１の巻回しよりも先に終了させ、波板１の巻回しは最終周の波板１ａと最終周の前の周に巻かれた波板１ｂとが重なり合う地点ｆまで行なうようにしたので、巻回したときの最終端において波板１による段差をなくすことができ、外筒４へ圧入した後においても波板１に変形のないメタルハニカム担体を製造することができる。 Thus, in the manufacturing method of the metal honeycomb carrier of the present embodiment, the winding of the flat plate 2 is finished before the winding of the corrugated plate 1 in the final winding, and the winding of the corrugated plate 1 is performed on the final winding. Since the corrugated sheet 1a and the corrugated sheet 1b wound around the circumference before the final circumference are overlapped, a step due to the corrugated sheet 1 can be eliminated at the final end of the winding. A metal honeycomb carrier in which the corrugated sheet 1 is not deformed even after being press-fitted into the cylinder 4 can be manufactured.
これによって、コーティング後の余剰触媒フィレットを削減して通気抵抗を低減することができるとともに、触媒コーティング後にガスが接触する波板の単位体積当たりの表面積を減少させることがないので、浄化性能を向上させることができる。 As a result, excess catalyst fillet after coating can be reduced to reduce ventilation resistance, and the surface area per unit volume of the corrugated plate with which the gas contacts after catalyst coating will not be reduced, improving purification performance. Can be made.
以上、本発明のメタルハニカム担体の製造方法について、図示した実施形態に基づいて説明したが、本発明はこれに限定されるものではなく、各部の構成は同様の機能を有する任意の構成のものに置き換えることができる。 As mentioned above, although the manufacturing method of the metal honeycomb support | carrier of this invention was demonstrated based on illustrated embodiment, this invention is not limited to this, The structure of each part is the thing of the arbitrary structures which have the same function Can be replaced.
