金属パネルの周壁が形成されている。A first embodiment of the present invention will be described with reference to FIGS. 1 to 3, the hollow metal panel 1 is composed of side plates 2 and 3 made of a pair of metal plates and interior members 4 and 5 having a U-shaped cross section disposed inside the side plates 2 and 3. 3, edges 20 and 30 are bent and formed so as to face each other, and the edges 20 and 30 form the peripheral wall of the metal panel.

ジェクション７は、それぞれ横部材41の内側からプレス
で押圧することにより外側に突出、形成させればよい。The interior member 4 is formed into a rod-shaped member having a U-shaped cross section by a vertical member 40 and horizontal members 41 formed at right and left ends of the vertical member 40. A plurality of spot welding projections 6 are formed at predetermined intervals in the longitudinal direction at positions corresponding to the upper and lower sides of the bases (near the vertical member 40) of the upper and lower horizontal members 41 of the interior material 4, and the spot welding projections 6 are formed. The lateral member 41 is displaced from the position 6 in the longitudinal direction.
An auxiliary projection 7 is formed at the tip of the.
The spot welding projection 6 and the auxiliary projection 7 may be formed so as to project outward from the inside of the lateral member 41 by pressing with a press.
スポット溶接用プロジェクション６は、後述のスポット

た際に横部材41が変形して縦部材40の上下端部が側板2,
3に接触して分流作用により溶接電流が逃がされるため
に好ましくない。The spot welding projection 6 is formed on the base portion of the horizontal member 41 to prevent distortion during later-described spot welding. For example, the distance b from the vertical member 40 is equal to the plate thickness t of the vertical member 40.
It should be set within 2.5 times. If this distance b is set larger than this, the horizontal member 41 is deformed when the projection 6 is pressed from above and below, and the upper and lower end portions of the vertical member 40 have side plates 2,
It is not preferable because the welding current is released due to the shunting action by contacting with 3.

個以上形成してもよい。However, as shown in FIGS. 5A and 5B, when the recess 43 is formed at the intersection of the vertical member 40 and the horizontal member 41 to increase the rigidity against deformation of the intersection, the above distance b May be set larger. Further, in this case, it is preferable to form the projections 6 at symmetrical positions with the recess 43 interposed therebetween so that the lateral member 41 is not twisted in the longitudinal direction by the pressing force of the electrodes. In addition, two 1st projections 6 are provided at one place (the place pressed by one spot welding).
You may form one or more pieces.

必要はなく、数箇所おきに設けてもよい。The auxiliary projection 7 is arranged at an intermediate position in the lengthwise direction between the spot welding projections 6, and the distance l from the spot welding projections 6 is preferably set to be 1.5 times the width B of the lateral member 41 or more. This is because the auxiliary projection 7 is for preventing the interior material 4 from falling during spot welding, and it is necessary not to apply a pressing force to the auxiliary projection 7 when it is pressed by the electrodes. The auxiliary projections 7 do not have to be provided between the spot welding projections 6, but may be provided at every several positions.

The advantage is that

Also, the structure may be exactly the same as that of the interior material 4.

い、内装材４と両側板2,3とを一体化させる。Next, a method of manufacturing the metal panel 1 using these members will be described. First, the above-mentioned interior material 4, on one side plate 2,
5 is placed in the arrangement as shown, and the other side plate 3 is further placed thereon, and as shown in FIG. 4, the upper and lower electrodes are placed at positions corresponding to the spot welding projection 6 through the side plates 2 and 3. It can be sandwiched between 10. Then, by energizing between both electrodes, the contact portion between the projection 6 and the side plates 2 and 3 is heated and melted to perform welding. This operation is sequentially performed for the spot welding projections 6 corresponding to the upper and lower phases, and the interior material 4 and the side plates 2 and 3 are integrated.

ン６の溶接に悪影響を及ぼすことはない。In this welding, spot welding projection 6
Since it is formed at the base of the lateral member 41, it is not bent and deformed even when the pressing force of the electrode 10 acts, and therefore, the flow dividing action does not occur and good welding is performed. Further, since the auxiliary projection 7 comes into contact with the upper and lower side plates 2 and 3 to function as a fall-prevention function, tilting is prevented even when the interior material 4 is pressed by the electrode 10, and the auxiliary projection 7 is not This part is not welded because it lies outside the area pressed by 10 and therefore does not adversely affect the welding of the spot welding projection 6.

なくなるからである。After the interior material 4 is welded, the interior material 5 is also welded in the same manner, whereby the whole is integrated. The interior material 5
It is necessary to set the dimensions of the edges 20 and 30 so that a slight gap is formed between the tips of the edges 20 and 30 so that the edges 20 and 30 do not come into contact with each other during welding. . Edge 20 and Edge 3
This is because when 0 and 0 come into contact with each other, a current flows through that portion, and the spot welding projection 6 portion cannot be welded well.

That is, in this example, the configurations of the horizontal member 44, the vertical member 45, and the projection 6 on the horizontal member are the same as above, but no extension is formed at the tip of the vertical member 45, and the vertical member 45 is not formed.
The projection 80 is formed directly on the tip of the.
The projection 80 is formed by forming a recess 81 with a punch in the plate thickness direction at the tip of the vertical member 45 to plastically deform and project the tip of the vertical member 45. Instead of forming the projection in this way, the projection 80 may be formed at the time of plate cutting. As a mode of forming the projection 80 at the tip of the vertical member 45 in this manner, the vertical member is as described above.
There are a case where the extension portion 42 is formed at the tip end portion of the 45 and the projection 8 is formed there, and a case where the projection 80 is formed directly at the tip end portion of the vertical member 45.

When the interior material 5 is welded, the auxiliary projection 7 comes into contact with the upper and lower side plates 2 and 3 to function as a fall-prevention function. Therefore, even if the interior material 5 is pressed by the electrode 10, inclination may occur. Since this is prevented, the auxiliary projection 7 is located outside the area pressed by the electrode 10 so that this part is not welded and thus does not adversely affect the welding of the projection 6.
