りするのが一般的である。(Prior Art) In a manufacturing method such as a radiator or a plate fin type heat exchanger in which flat plates and corrugated plates are alternately layered and brazed to each other, the brazing material is supplied by spraying powdered braze on both sides. It is general that the flat plate and the corrugated plate applied in step 1 are alternately stacked, or the brazing foil is sandwiched between the flat plate and the corrugated plate and stacked.

ロウ材を塗布する方法が知られている。Further, in the case of a manufacturing process of an exhaust gas purifying metal carrier for manufacturing a cylindrical honeycomb structure (hereinafter referred to as a honeycomb body) by stacking flat foils and corrugated foils and spirally winding them, Japanese Patent Application Laid-Open No. 61-
As known in 199574, after immersing the end face of the honeycomb body in a binder liquid, a brazing material powder is sprayed from the end face,
A method of applying a brazing material is known.
(発明が解決しようとする課題) 従来のロウ材塗布方法ではハニカム体接合部すなわち
波箔の山頂部と平箔とで構成される接合部近傍にのみ、
ロウ材を十分な量だけ均一に塗布することが困難であ
り、以下の問題を生じていた。(Problems to be Solved by the Invention) In the conventional brazing material coating method, only in the vicinity of the joining portion formed by the honeycomb body joining portion, that is, the peak portion of the corrugated foil and the flat foil,
It is difficult to uniformly apply a sufficient amount of the brazing material, and the following problems occur.
ロウ材が、接合に不要な互いに接触しないハニカム体
の部分にも塗布されるため、ロウ材使用量が増える。ま
たロウ材の総量が多くなるため、金属箔にロウ材の成分
が拡散しロウ食や収縮等が発生し易くなる。Since the brazing material is also applied to the portions of the honeycomb body which are not in contact with each other and are not necessary for joining, the amount of brazing material used increases. In addition, since the total amount of the brazing material is large, the components of the brazing material are diffused in the metal foil, and wax corrosion and shrinkage are likely to occur.
すなわち、前記公報のように、ハニカム体端部をバイ
ンダー液に浸漬すると、波箔と平箔の接触部以外、つま
り波箔、平波の面にもバインダーが付着し、その部分に
もロウ材が付着し、上記した問題が生ずることになる。That is, as described in the above publication, when the end of the honeycomb body is dipped in the binder liquid, the binder adheres to a portion other than the contact portion between the corrugated foil and the flat foil, that is, the surface of the corrugated foil or the flat wave, and the brazing material also adheres to that portion. Will be attached, and the above-mentioned problems will occur.
平板と波板とを交互に層状に重ねてロウ付けする場合
には、平板と波板の間には、ロウ材が挟み込まれている
ため、ハニカム体の見掛けの厚みがそのぶん厚くなって
おりロウ付け前に、ロウずけ後の厚みを正確に予測し調
整する事が困難である。When brazing flat plates and corrugated plates alternately in layers, the brazing material is sandwiched between the flat plates and corrugated plates, so the apparent thickness of the honeycomb body is thicker than that and brazing is performed. Before, it is difficult to accurately predict and adjust the thickness after brazing.

旋状に巻き込んだのち、接合部にロウ材を供給しなけれ
ばならず従来のロウ材供給方法では接合部近傍にのみ十
分なロウを塗布することが困難であった。When manufacturing a cylindrical honeycomb structure by stacking flat foil and corrugated foil and spirally winding them, it is not possible to drive the gap created after the brazing material is melted by weighting etc. when brazing, The method of sandwiching the brazing material between the flat plate and the corrugated plate cannot be adopted. For this reason, the flat foil and the corrugated foil are overlapped and rolled up in a spiral shape, and then the brazing material must be supplied to the joint portion. In the conventional brazing material supply method, sufficient brazing can be applied only in the vicinity of the joint portion. It was difficult.

少量ずつ叶出するディスペンシング方式があるが、人手
でノズルを操作するためハニカム体の接合のような多数
の接合点に供給するには、能率が悪く、またノズルを近
ずける事も出来ない場合が多い。In order to accurately supply the wax in the vicinity of the brazing part, there is a dispensing method in which a mixture of a gel binder and a brazing material powder is gradually released from a thin nozzle, but since the nozzle is manually operated, In many cases, it is inefficient to supply to a large number of joining points such as joining, and it is often impossible to approach the nozzle.
本発明は、前記のディスペンシング方式で丁寧にロウ

できる。(Means for Solving the Invention) According to the present invention, a corrugated metal foil (corrugated foil) and a flat metal foil (flat foil) are alternately superposed and wound, or laminated to form a honeycomb body. Then, when fixing the contact portion between the corrugated foil and the flat foil by brazing, the end face of this honeycomb structure, that is, the end face in the axial direction of the honeycomb structure in which the wavy honeycomb surface is exposed is a binder liquid. A method for brazing a honeycomb structure, which comprises contacting the surface of the corrugated foil with a flat foil to suck up a binder, and then spraying a brazing material powder to apply the brazing material to the contacting portion. Is the first invention. A surfactant can be added to the binder liquid to adjust the amount of the binder taken up.

け方法を第2の発明とする。As another method of the present invention, in the case of brazing the contact portion between the corrugated foil and the flat foil forming the honeycomb structure, at a predetermined position, the flat foil coated with a solid or liquid oil and fat is a corrugated foil. A second invention is a method for brazing a honeycomb structure, which is characterized in that a binder and a brazing material powder are supplied to the honeycomb structure which is formed by being rolled up or rolled up in the same manner as in the first invention.
以下に本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明において、ハニカム構造体にバインダーを供給

液中に浸漬することなくバインダー表面と接触させるこ
とにより、波箔、平箔の接触部だけにバインダーが吸い
上げられ、接触部以外の部分にはバインダーは付着しな
い。In the present invention, the method of supplying the binder to the honeycomb structure is to create a state in which the binder is sucked up by the capillary phenomenon at the contact portion made of the corrugated foil and the flat foil. At the end face of the honeycomb structure, the honeycomb surface formed by the corrugated foil and the flat foil is exposed, and by contacting this surface with the binder surface without immersing it in the binder liquid, the corrugated foil and the flat foil are brought into contact with each other. The binder is sucked up only to the part, and the binder does not adhere to the part other than the contact part.
本発明の好ましい実施例は、バインダー液に半分程度
浸したスポンジの上にハニカム構造体の端面を置いて、

構造体の端面から十分な量散布し、バインダーの付着し

材を塗布するものである。In a preferred embodiment of the present invention, the end face of the honeycomb structure is placed on a sponge half-soaked in a binder liquid,
Without immersing the honeycomb structure in a binder liquid,
That is, the binder liquid is sucked up to the bonded portion of the honeycomb structure by the capillary phenomenon. After that, a sufficient amount of wax powder is sprayed from the end face of the structure, and the brazing material is applied so that the brazing powder is adhered only to the portion where the binder is adhered.

させることが出来る。このあと、ハニカム体の端部から
ロウ粉末を散布すると、ロウの粒子はバインダー液の付
着している部分にしか付着しないから結果として平箔と
波箔の接触部にだけロウ材を塗布することが出来る。That is, since there is no gap or a very small gap between the flat foil and the corrugated foil in the portion of the honeycomb structure to be joined, the binder supplied from the binder liquid surface or the sponge rises in the gap due to the capillary phenomenon. This action makes it possible to simultaneously and uniformly attach the binder liquid to a large number of joints at the same time by a simple operation as long as the flatness of the end face of the honeycomb structure is secured. After that, when the wax powder is sprayed from the end of the honeycomb body, the wax particles adhere only to the part where the binder liquid adheres, and as a result, apply the brazing material only to the contact part between the flat foil and the corrugated foil. Can be done.

力が大きく減少するため、それ以上上昇出来なくなる。
その結果、バインダー液の付着範囲が限定され、これに
ロウ材を散布すると、限定されたロウ塗布範囲を有する
ハニカム体が製造出来る。In addition, in a honeycomb body in which the brazing range is limited to a certain distance from the end face rather than the entire length of the contact portion between the flat foil and the corrugated foil, solid or liquid oil or fat is applied to both sides of the flat foil along the brazing boundary line. After applying it, wrap it up with the wave foil,
After forming the honeycomb structure, the binder liquid is sucked up as described above. The binder liquid sucked up by the capillary phenomenon cannot be further raised because the interfacial tension between the oil and fat portion with the foil is greatly reduced.
As a result, the adhesion range of the binder liquid is limited, and when a brazing material is sprayed on this, a honeycomb body having a limited wax application range can be manufactured.
本発明に使用するバインダー液としては、例えばポリ
ビニルアルコール溶液があり、これには、場合によって
界面活性剤を加えることによりバインダーの表面張力を

げ高の調整が可能となる。As the binder liquid used in the present invention, there is, for example, a polyvinyl alcohol solution, in which the surface tension of the binder can be adjusted by adding a surfactant depending on the case, and it is possible to increase the suction strength to the honeycomb structure contact portion. Can be adjusted.

が完了する。Fig. 1 is a diagram showing a step of sucking up a binder into a honeycomb body by utilizing a capillary phenomenon, and Fig. 2 shows a part of the honeycomb body 1 of Fig. 1, in which the binder is attached to the joint part. 2 is a diagram showing a honeycomb body 1 in which flat foil 4 and corrugated foil 5 are overlapped and rolled up in FIG.
After degreasing, as shown in FIG. 1, the end E having an exposed wavy cross section is placed on the sponge 2 half-soaked in the binder liquid 3 to suck up the binder liquid 3. The surface tension of the binder liquid is adjusted with a surfactant in order to secure a sufficient wicking amount and wicking height. As shown in FIG. 2, the binder 6 surely adheres to the joint portion. FIG. 3 is a diagram showing a spraying state of the brazing material. After the binder is sucked up, the brazing material is promptly sprayed as shown in FIG. In this embodiment, as shown in FIG. 3, while the brazing material 8 (powder) is gas-conveyed and sprayed in an elliptical shape by the nozzle 7, the honeycomb body 1 is rotated thereunder to uniformly distribute the brazing material 8 throughout. Attach it. The amount of the brazing material 8 applied can be increased or decreased depending on the amount of the binder attached and the amount of the brazing material sprayed. Therefore, the amount of the binder and the amount of the wax applied are adjusted in advance so that an appropriate amount can be applied. FIG. 4 shows a wax coating state on the honeycomb body 1. In FIG.
4 is a flat foil, 5 is a corrugated foil, and 8 is a powdered brazing material. The honeycomb body 1 on which brazing is finished is dried in a binder solution and then placed in a brazing furnace and heated to complete brazing.

でロウ設部を特定の範囲に限定することが出来る。For example, if the fat and oil 9 is applied in a streak shape to the flat foil in advance, and it is wound together with the corrugated foil, and then the honeycomb body is placed on the sponge soaked in the binder liquid 3 as in FIG. As a result, the joint rises, but the fat 9 prevents the binder riser 10 and above from rising. Therefore, as shown in FIG. 3, even if the brazing material is sprinkled, it adheres only to the portion of the binder liquid and does not adhere to other portions, so that the brazing portion can be limited to a specific range.
