【発明の属する技術分野】この発明は、例えば電磁誘導

の製造に用いられる異種金属材料の接合方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for joining dissimilar metal materials used for manufacturing cooking utensils such as pots, pans and rice cookers which are heated by electromagnetic induction.

合されたものに構成されている。2. Description of the Related Art Since the above-mentioned electromagnetic cooking utensils are heated by electromagnetic induction, they generally have good thermal conductivity but low magnetic permeability (including alloys thereof; The same) is joined to an iron-based magnetic material such as magnetic iron or SUS, which has a low magnetic conductivity but a high magnetic permeability.

駄でコスト高につくという欠点があった。Such joining of aluminum and iron-based magnetic material has been conventionally performed by a so-called clad rolling method in which an aluminum coil and a coil of iron-based magnetic material are clad-rolled and then molded. However, the joining by the clad rolling method has the following drawbacks. In other words, the electromagnetic cooking utensil is sufficient for heating, etc. if the iron-based magnetic material is present only at the bottom, but it is difficult to partially bond it by the clad rolling method. Since the magnetic material is present, there is a drawback in that it is wasteful in terms of material and economy and the cost is high.

についても問題を有するものであった。[0004] Further, it is also a part of manufacturing a main body of an electromagnetic cooking utensil from an aluminum material and then spraying magnetic iron powder on the bottom of the main body to partially bond an iron-based magnetic material. However, with this method, it is not easy to obtain a thick magnetic iron film, so it takes time and effort to obtain a thick magnetic iron film in order to secure a sufficient electromagnetic induction effect,
After all, there was a drawback that the cost was high. In addition, there was a problem in corrosion resistance.

（特願平６−２８５２８８号）。Therefore, the Applicant has formed a ring-shaped groove on the joint surface of the iron-based magnetic material and pressurizing the aluminum material and the iron-based magnetic material in the joining direction while using the center of the groove as the rotation axis. It has been proposed to join an aluminum material and an iron-based magnetic material by a friction welding method of rotating relative to each other (Japanese Patent Application No. 6-285288).

なお改善の余地があった。According to this, it is possible to partially join the two members, and the existence of the ring groove expands the joining area to increase the joining strength. However, the friction welding method itself is complicated. In addition, there is still room for improvement with respect to the increase in bonding strength.

優れた異種金属材料の接合方法の提供を目的とする。The present invention has been made in view of the above technical background, and makes it possible to partially join one member to the other member by a simple means and also to increase the wall thickness of both members. An object of the present invention is to provide a method for joining dissimilar metal materials, which can be made thick and is excellent in joining strength (adhesion).

The bottomed biting hole (3) is formed, and the biting hole (3) has a cross-sectional area in at least part of the depth direction larger than the area of the opening (3a), and After the joining surfaces of both members (1) and (2) are overlapped, the soft side metal material (1) is pressed by a forging method in the joining direction to deform the soft side metal material (1) and The gist is a method of joining dissimilar metal materials, which is characterized in that the bite hole (3) is made to bite into a filled state.

To form The biting hole (3) prevents the peeling of both members at this portion by deforming the aluminum material by forging the aluminum material described later and allowing the meat to bite into the biting hole (3) in a filled state. It is for producing an anchor effect. And in this invention,
It is necessary that the biting hole (3) has a cross-sectional area in at least a part in the depth direction larger than the area of the opening (3a). This prevents the meat of the aluminum material that digs into the hole from coming off the opening (3a) of the hole,
This is because it exerts a stronger anchor effect. As the concrete shape of the bite hole (3), for example, a spherical shape or a substantially spherical shape as shown in FIG. 2 or a circular cross section whose inner diameter continuously increases from the opening to the middle in the depth direction From there, there are vase-shaped ones with a continuously decreasing inner diameter and flat bottom surface, and flask-like ones with a circular cross section and continuously expanding inner diameter as the hole bottom reaches and a flat bottom surface. It can be illustrated. Further, the cross section does not necessarily have to be circular.

As the most simple and high-speed processing, a method using electron beam irradiation can be mentioned. This is because the electron beam irradiation naturally forms the spherical or substantially spherical bite hole (3) as shown in FIG. The electron beam irradiation conditions and the like may be appropriately set to values that can melt the surface of the iron-based material (2).

この場合の加熱温度は、１５０〜３５０℃が好ましい。Next, the relatively soft aluminum material (1) is pressed by a forging method in the joining direction with the iron-based magnetic material (2) (the arrow direction in FIG. 1B). By this forging method, the joint surface of the aluminum material (1) is plastically deformed along the shape of the bite hole (3) of the iron-based magnetic material (2) as shown in FIG. As shown in, the biting hole (3) is bitten into the filling state. Although the forging may be cold or hot, the aluminum material (1) can be heated and softened in that the deformation resistance of the aluminum material (1) can be reduced to reduce the joining energy applied from the forging tool to the aluminum material during forging. It is preferable to perform hot forging in the as-deposited state.
In this case, the heating temperature is preferably 150 to 350 ° C.

The meat of the aluminum material (1) intrudes into the filled state to prevent the two members from peeling off, and a strong bonding state between the aluminum material (1) and the iron-based magnetic material (2) is secured.
