A7 B7 printed by the Consumer Labor Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Description of the invention (1) (the desired field of invention) The present invention relates to, for example, pots, frying pans, rice cookers heated by electromagnetic induction, etc. The joining method of different kinds of gold and gold materials for the preparation of utensils for conditioning. (Problems to be solved by the prior art and the present invention) As mentioned above, the electromagnetic conditioning device is heated by electromagnetic induction, so in general, although bonding, the thermal conductivity is good, but aluminum with low permeability (including aluminum alloy, the following Same), which is composed of iron-based magnetic materials such as magnetic iron, stainless steel, etc., which have poor thermal conductivity but high permeability. This kind of aluminum and iron-based magnetic materials have been used in the past. (Steel coil) It is carried out by so-called cladding rolling method which is formed after clad rolling. However, there are the following disadvantages when joining according to the guard roll method. That is to say, the equipment for electromagnetic conditioning should only have iron-based magnetic materials at the bottom, which is sufficient for heating. However, it is difficult to perform partial bonding by the protective roll method, so iron will exist in the entire aluminum material. Magnetic materials are therefore economically wasteful and have the disadvantage of high cost. Another part of people use aluminum material to make the body of electromagnetic conditioning equipment, then spray magnetic iron powder to the bottom to join the iron-based magnetic material. However, it is difficult to obtain a thick magnetic iron film by this method, so if a thick magnetic iron film is to be obtained in order to obtain a sufficient electromagnetic induction effect, it is time-consuming and labor-intensive, thus increasing costs is its disadvantage. Furthermore, corrosion resistance is also a problem. Therefore, the applicant proposed to form the paper size on the joint surface of the iron-based magnetic material and apply the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the precautions on the back before filling this page). Order A7 B7 Economy Ministry of Central Standards Bureau Beigong Consumer Cooperative Inquiry 300862_ V. Description of the invention (2) The ring-shaped groove, by which the aluminum material and the iron-based magnetic material are pressed to the joint, with the center of the groove as the rotation axis Relatively rotating friction pressure bonding method to join aluminum and iron-based magnetic materials. (Japanese Patent Application No. 6-285288). According to this method, although the joining of two parts can be implemented, the operation of the friction joint itself is cumbersome, and at the same time, the increase in the joining strength still needs to be improved. The present invention was developed in view of the above technical background. To provide a method of joining which can be used to implement the joining of one member to the other member in a simple manner, at the same time, the material thickness of the two members can be increased, and the joining strength (adhesion) is also excellent. . (Means for solving the problem) In order to achieve the above object, one of the inventions is: referring to the reference numerals in the drawing, that is, when joining two gold tantalum materials (1) (2) with different hardnesses, the metal material on the hard side (2) On the joint surface, a plurality of bottomed sink holes (3) are formed in advance, and at least a part of the cross-sectional area of the sink hole (3) in the depth direction is set to be more than the opening (3 a) The area is large, and after the joining surfaces of the two members (1) (2) are superimposed, the metal material (1) on the soft side is deformed by applying pressure in the joining direction to infiltrate the sink hole in the filled state ( 3) Its characteristics.

Description of the invention (4) Therefore, these methods are relatively easy to form the desired sink hole (3) shape. (Embodiment of the invention si) Next, an embodiment of applying the present invention to the manufacture of an electromagnetic conditioning device will be described. When you want to manufacture electromagnetic conditioning utensils, first prepare a plate-shaped aluminum material and iron-based magnetic material of a prescribed size. The aluminum material is used to constitute the body (2 0) of the electromagnetic conditioning device (1 0) as shown in FIGS. 3 and 7. It is better to use the one with good thermal conductivity. Use A1050, A1070, A 1 1 〇〇 Suitable for aluminum. In particular, A3003'A3004 is used when considering the shapeability of the shape of the utensil. Aluminum is more suitable. The iron-based magnetic material is used to form a heat generating member (30) that generates heat by electromagnetic induction, and is bonded to the outside of the bottom of the body (20). The iron-based magnetic material is preferably a magnetic SUS material such as SUS430 or SU405. Next, as shown in FIGS. 2 and 5, among the aluminum material and the iron-based magnetic material to be joined, a large number of sink holes (3) are formed on the joining surface of the opposing hard iron-based magnetic material (2). The sink hole (3) is formed by forging of the aluminum material described later, which deforms the aluminum material and invades its filling state into the sink hole (3), and an anchor that prevents the peeling of the two members occurs in this part Fixed effect. The sink hole (3) shown in FIG. 2 is a sink hole (3) with a bottom. The cross-sectional area of at least a part of the depth direction is set to be larger than the area of the opening (3a). As a result, the size of the paper that can prevent the aluminum material invading into the hole is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the precautions on the back before filling this page) .t '" -7-A7 _B7_ printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Invention description (5) It comes out from the opening of the hole (3 a), and can play a strong anchoring role. In addition, the specific shape of the bottomed recessed hole (3) is, for example, spherical or large ii shown in FIG. 2: spherical, or circular in cross-section and connected by the inner diameter from the opening toward the middle of the depth direction At the same time, the expansion of the bottom of the hole continues to shrink towards the bottom of the hole, the bottom of the pot is flat, or the cross-section is rounded to the bottom of the hole. It can also be round. As described above, the means for forming the bottomed recessed hole (3) having a larger cross-sectional area in the depth direction than the opening area is not particularly limited. However, the simplest method that can be processed at a high speed can propose an electron beam irradiation method. Because of the irradiation of the electron beam, it can naturally form a spherical or even spherical sink hole (3) as shown in FIG. 2. The irradiation conditions of the electron beam and the like may be appropriately set to the value of the surface of the meltable iron-based material (2). The sink hole (3) shown in FIG. 5 is a sink hole (3) penetrating in the thickness direction of the iron-based magnetic material (2), and is set to gradually break from the opening of the joint surface (3 a) to the depth direction The area will increase in the shape of promotion. As a result, the material of the aluminum material intruding into the sinking part (3) can be prevented from coming out from the opening part (3a) of the hole, and a strong anchoring effect can be exerted. The cross-sectional shape of the above-mentioned through-hole (3) may be a circular shape or a shape similar to a circular shape, and an angular shape may also be used. The method of forming the sink hole (3) that gradually increases the cross-sectional area from the opening (3a) of the joining surface to the depth direction as described above is not particularly limited, but the simplest method is shown in FIG. 6, Use a punch with a small diameter pushing toward the tip (4), and drill holes from the opposite side of the joint surface. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) ~ ~ -8-( Please read the precautions on the back before filling in this page) Order the A7 B7 printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. The method of invention (6), or the method of melting by irradiating the laser beam. These holes are processed, and as shown in FIG. 6, when a burr (3b) occurs on the opening edge of the joint surface, the burr will be pressed during the processing of aluminum material such as i forging, and at the same time, the aluminum material Will hide it. Therefore, the raw edge can be abandoned as it is. When the iron-based magnetic material (2) is provided with a penetrating recessed hole (3), its number may prevent its induction heating function from being exerted. Therefore, the size of the recessed holes (3), that is, the size of the openings (3a) provided at a uniform interval of 3 to 6mm is preferably 2 to 4mn. Next, the iron-based magnetic material (2) and the aluminum material (1) prepared in the above method are joined. As shown in Fig. 1 (a) and Fig. 4 (a), the joint surface of the laminated aluminum material (1) and the iron-based magnetic material (2). The iron-based magnetic material (2) may be arranged at a part necessary for induction heating. Generally, it is arranged at a predetermined position of the aluminum material (1) so as to be located outside the bottom of the electromagnetic conditioning appliance. Next, the relatively soft material (aluminum material (1)), for example, is pressed by the forging method to the joining direction of the iron-based magnetic material (2) (Figure 1 (b), Figure 4 (b) arrow direction The forging method follows the shape of the above-mentioned sink hole (3) of the iron-based magnetic material (2) as shown in FIG. 1 (b) and FIG. 4 (b), and the joint surface of the aluminum material (1) will plastically deform As shown in Fig. 1 (c) and Fig. 4 (c), the filled state penetrates into the sink hole (3). Although forging is possible in cold room or hot room, the deformation resistance of the aluminum material (1) is reduced However, in terms of reducing the joint energy given by the forging tools during forging, it is better to make the aluminum material (1) heated and softened in the hot forging, and the heating temperature at this time is in accordance with the Chinese paper standard.

-13-Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs, printed seal 3〇〇862 _ ^ _ V. Description of the invention (11) From the above Table 1 and Table 2, it can be known that the bonding surface of the aluminum plate of the implemented strain of the present invention is filled after its deformation Of the SUS plate penetrated into the majority of the holes to show a strong bonding state, and there is no void at the bonding interface. There is no SUS board. There is a comparative product that is formed into a hole and cannot be joined. From the comparison of samples No. 1 and 3 and No. 6 and 8, it can be seen that hot forging can save the joint energy during forging more than cold forging. Effect of the Invention The present invention is based on the above-mentioned method, the gold side material on the soft side is infiltrated into the metal side material on the hard side in the state of filling into a large number of pre-set holes to join the two, so it can effectively prevent aluminum The material can fall off from the hole, and it can exert a strong and strong anchoring effect, so that it is not easy to peel off, and the bonding material has excellent bonding strength. And the pressure deformation of the means of intruding into the hole in the filled state of the metal material on the soft side is done by the forging method, so it is easy to perform the joining operation, and when the protective roll method is used, the two members must be removed. In the case of ground bonding, one part of the component may be partly bonded to the other component. And because it can be partially joined, one of the components can be shaped into a predetermined shape and then joined with another member, so the degree of freedom of product manufacturing is expanded. Furthermore, if the bottomed hole is formed by the irradiation of an electron beam, Due to its melting on the surface, it is natural to complete a part of the hole with a cross-sectional area greater than the area of the opening in the depth direction, so it is very simple to form a bottomed hole.
