として組付ける方法も生産性が悪い。(Prior Art) For example, air cleaner cases used in motorcycle engines are mainly molded from synthetic resin.
As shown in FIGS. 1 and 2, the air cleaner case has a box-shaped case body 1 that accommodates a cleaner element, as well as an air intake port 2 and an air outlet port 3. Among them, the air outlet 3 extends a joint tube 4, and its tip is connected to an air chamber for distributing to a carburetor or a plurality of carburetors for multi-cylinder use. In the latter case, the joint tube 4 is often set to have an elliptical cross section in order to equalize the distribution. However, since the tube with an elliptical cross section has low rigidity in the direction of its short axis and diameter and is easily deformed, a problem arises in the sealing performance of the connection with the air chamber. In order to increase the rigidity, it is possible to increase the wall thickness, but this increases the cost and makes it difficult to mold. A method of providing reinforcing ribs 5 along the minor axis diameter is also effective, but in order to obtain sufficient strength, the rib width must be increased and the flow cross-sectional area must be reduced. Furthermore, integrally molding the reinforcing ribs from synthetic resin requires complicated blow molding or other molds, and methods of assembling them as separate parts also have low productivity.

ものである。(Problems to be Solved by the Invention) As described above, when a hollow resin body has a cylindrical opening or the like and requires reinforcing ribs because the opening has weak rigidity, the mold becomes complicated. In view of the problem of low productivity, this invention aims to solve this problem, and aims to span a metal rib over an opening with high productivity using an extremely simple method. This invention provides a reinforcing device for hollow resin bodies.

(Means for Solving the Problems) To achieve the above object, the reinforcing device for a hollow resin body of the present invention has an opening in which divided bodies of heat-melting synthetic resin are joined by high-frequency induction welding. In the hollow resin body, a bonding surface is set to cross the opening, and a metal wire for high-frequency induction heating that runs along the bonding surface is also passed across the opening and remains in the opening as it is after welding. configuration.

Both half cases (divided halves) 1a and 1b are molded from heat-melting synthetic resin. In this case, the dividing plane is set to a plane that includes the necessary reinforcing ribs. In other words, the joint tube 4 has an elliptical cross-section, and it is necessary to provide a reinforcing rib in the minor axis diameter direction on the end face, so the joint tube 4 is divided into left and right halves by the surface including this reinforcing rib. do.

面５を凹溝と凸条で組合わせるとよい。 High frequency induction welding is used to join the half cases 1a and 1b. In high-frequency induction welding, as shown in FIG. 4, the two halves of the cases 1a and 1b are temporarily assembled by sandwiching a heating metal wire 6 along the joint surface 5, and then high-frequency electromagnetic waves are applied to this by a high-frequency induction coil 7. In this method, the metal wire 6 is heated, and the synthetic resin on the joint surface 5 is melted and welded by this heat.
The metal wire 6 is embedded in the bonding surface 5 as it is.
In terms of holding the metal wire 6 during temporary assembly and strengthening the welding, it is preferable to combine the joint surface 5 with a concave groove and a convex strip.

It is particularly strong in the tensile direction, and effectively prevents it from deforming into a circular shape when the outer periphery is tightened with a band-type clamp when connecting it to an air chamber. Since the metal wire 6 is continuous all around, it does not easily come off. If even greater strength in the compression direction is required, the wire diameter and cross-sectional shape of the metal wire 6 are set to meet the requirements.

As described above, in the reinforcing device for a hollow resin body according to the present invention, in order to join the divided halves, a metal wire for high-frequency induction heating is passed along the joint surface through the opening and left as a reinforcing rib after welding. With this structure, the metal reinforcing rib can be easily spanned over the opening without using any special parts or auxiliary equipment or adding any additional processing steps. Therefore, it is possible to produce lightweight and highly rigid hollow resin bodies with high productivity.
It is effective and can be provided at low cost.
