), a cap-shaped protrusion is formed on each of two thin metal plates to be joined in a separate process, and the thin metal plates are assembled with both protrusions fitted together. It is manufactured by overlapping the two protrusions, then fitting them into a plunger-shaped anvil projection, and applying a punch from the opposite side of the anvil to mechanically engage the free ends of both protrusions. The first protrusion on the first thin metal plate, which is the outer side in the mated state, is partially crushed after the molding to reduce its height. A process is performed in which the second protrusion on the inner second thin metal plate is fitted onto such a first protrusion and the free ends of both protrusions are engaged with each other. The above-mentioned 1-lunge-shaped anvil used in this process has a spring load Wffl that is moved and biased by a spring in the direction of both protrusions. By enlarging the free ends of both protrusions in the outer circumferential direction by reducing the width, an enlarged portion is formed that interengages with the free ends of the protrusions.

ととなる。The mechanical mutual engagement formed by bending the pre-formed protrusion and crushing the entire side peripheral wall to expand the free end in the outer circumferential direction is achieved by the mechanical mutual engagement formed by the expansion of the free end in the outer circumferential direction. The degree of engagement is relatively small compared to the engagement in a state where the free end portion is slightly protruded in the outer circumferential direction from the inner surface position of the side circumferential wall of the first protrusion, which is positioned outward. Therefore, when the conventional coupling structure is used in applications where a large force is applied in the direction of separating both thin metal plates, even a slight deformation of the free end of the protrusion can cause the coupling to fail.

, the lower surface of the sheet metal assembly rests on the surface 52 of the die portion 38 and is inserted. A press (or some other device) is then actuated to move the punch 16 downwards in the direction of the metal sheet a+b and the die land path 10 as shown in the drawing. When the engagement of the punch IFS and the metal sheet occurs, the metal sheet is pulled downwardly toward the upper surface of the annobil 36, which is indicated by reference numeral 60, and protrusions are formed on both ends of the metal sheet. Since the opening formed by the groove 56 is rounded or rounded 58 and a gap (clearance) is provided between the opening and the punch 16, the thin metal plate cannot be broken or sheared. It doesn't happen. When the punch 16 approaches the anvil 36 to a distance less than the sum of the initial thicknesses of the sheet metal at b, a sideways extrusion or extrusion of the metal occurs, causing the sheet metal a.

It rotates outward as shown in Figure 8. A strong, permanent and leak-proof bond is now formed;
The punch 16 is then retracted to the position shown in FIG. 2, and the material to be joined is removed. It should be noted that when using this apparatus, only the punch 16 is actuated and the anvil 86 remains stationary. When the material to be bonded is removed, the coil spring 46 causes the die portion 88 to , returned to the open chain position shown in FIG.

For example, FIG. 9 illustrates four different punch shapes that can be used. In FIG. 9(a), when the die 1 is 1≦minute 88a, a bond with a circumference of 1'l larger than a single circular bond is required due to either anti-rotation properties or strength. Three circular holes (circular openings) 64 are provided for this purpose. In Figure 8g9(b), the die portion 38b has a diamond-shaped through hole or opening 66 which provides a bond with a strength comparable to that provided by the previously described device, but which produces a bond with superior cycling resistance. have.
