However, the surface of the cast product is rough, so in order to reduce air resistance to improve intake efficiency, it is necessary to finish at least the inner surface to make it smooth, which poses the problem of tedious work. Ta. Furthermore, because it is impossible to finish the entire inner surface of the intake manifold smooth due to its shape, it has not been possible to sufficiently reduce air resistance to improve intake efficiency. Further, in cast products, the thickness of the peripheral wall cannot be reduced beyond a certain limit due to the flowability of the metal during casting, so there is a problem in that the weight becomes large.

Therefore, an intake manifold consisting of an aluminum main pipe serving as a plenum chamber and an aluminum branch pipe was considered. The main pipe and branch pipes in this intake manifold are formed by performing various processing on a wrought aluminum tube formed by plastic working such as extrusion, impact extrusion, forging, and press working.

For example, the main pipe is made by bulging the circumferential wall of a pipe made of wrought aluminum material to form multiple bulges, drilling holes in the closing wall at the tip of the bulge, and then burring holes in the closing wall at the tip. It is made by bending the surrounding part outward and enlarging its tip to form a cylindrical outward protrusion for connecting a branch pipe. The intake manifold is manufactured by fitting one end of the branch pipe into the cylindrical outward protrusion for connecting the branch pipe and brazing the two.

However, in order to manufacture this intake manifold, the peripheral wall of a wrought aluminum pipe is bulged to form multiple bulges, holes are drilled in the closing wall at the end of the bulges, and then burring is performed. By machining, the portion of the tip closing wall around the hole is bent outward and its tip is expanded to form a cylindrical outward protrusion for connecting a branch pipe, and one end of the branch pipe is further bent into a tube for connecting a branch pipe. There is a problem in that manufacturing is troublesome because it needs to be fitted into the outwardly protruding portion and brazed together. In particular, since the cost of bulge processing is high, there is a problem in that it leads to an increase in cost. Furthermore, there is a problem in that there is little freedom in designing the shape of the intake manifold.

That is, an anti-crimping agent is printed in the desired pattern on one side of one of the two aluminum plates, and the other plate is crimped to this surface to create a laminated plate with a non-crimped part. It is manufactured by the so-called roll bonding method, which introduces fluid pressure such as air pressure into the non-crimped portion of the plate. To explain in more detail the method for manufacturing the intake manifold, an aluminum plate (1
Prepare two sheets of aluminum plate (10) and print an anti-crimping agent in the desired pattern on one side of one aluminum plate (10).
By crimping the other aluminum plate (IO) to this surface, a laminated plate having a plurality of sets consisting of a non-crimped part for forming a tubular bulge for a plenum chamber and a non-crimped part for forming a tubular bulge for intake branch and delivery. Create (2). This mating plate (2) has a non-crimped part for forming a tubular bulge that is thicker than the plenum chamber tubular bulge (3) and will serve as the throttle body mounting flange (5), and a cylinder head bulge. A non-crimping portion (11) for forming a connecting flange (6) is also provided. Next, this laminated board (
2) a non-crimped part for forming a tubular bulge for the plenum chamber;
Fluid pressure such as air pressure is introduced into the non-crimped part for forming the tubular bulge for intake branch and delivery and the non-crimped part to form the tubular bulge that will become the flange (5) for attaching the throttle body. The sections are pre-inflated to form tubular bulges that are each thinner than the final state. At this time, the non-crimping portion (11) for forming the flange (6) for connection to the cylinder head is kept in a non-bulging state. Thereafter, the laminated plate (2) is cut into a desired shape, and the pre-inflated tubular bulging portion is main-inflated into a tubular bulging portion for a plenum chamber (3).
The tubular bulge (12) that will become the intake branch/delivery tubular bulge (4) and the throttle body mounting flange (5) are formed (see Figure 2). At this time, the flange (6) for connection to the cylinder head is formed. 〉Non-crimped portion (11) for forming
In this step, the space between both aluminum plates (IO) is sealed to prevent fluid pressure from escaping between both aluminum plates (10). Finally, the tubular bulging portion (12) is expanded outward, and the non-crimped portion (11) is bent outward to form both flanges (5) and (6). In this way, the intake manifold (1) is manufactured.

Effects of the Invention The intake manifold of the present invention includes a metal laminated plate, a plenum chamber tubular bulge portion with at least one end opening at the periphery of the laminated plate, and a tubular bulge portion for the plenum chamber that is separated from the plenum chamber tubular bulge portion toward the periphery of the laminated plate. Since the air intake manifold is formed with a tubular bulge for air intake branching and delivery that extends from the side and has its tip opened at the periphery of the laminated plate, it is possible to achieve a reduction in weight compared to a conventional air intake manifold. Further, in the intake manifold according to the present invention, for example, an anti-crimping agent is printed in a desired pattern on one side of one of the two metal plates, and the other plate is crimped to this surface to form a non-crimped part. It can be manufactured using the so-called roll bonding method, which involves creating a laminated plate with a laminate and introducing fluid pressure such as air pressure into the non-crimped part of the laminated plate, so it can be manufactured using the so-called roll bonding method. etc., making it easy to manufacture and reducing manufacturing costs. Moreover, since the degree of freedom in designing the plenum chamber tubular bulge and the intake branch/delivery tubular bulge is increased, it is possible to easily manufacture products that can be applied to various types of engines.
