板溶着が有用で実用的なものと推測される。そし
て、更に詳言すれば、振動溶着ではその接合面に
脱落し易いバリを発生する欠点を伴うため、熱板
溶着が最も望ましい接合手段と考えられる。[Conventional technology] In recent years, surge tanks installed in vehicle engines have been replaced with conventional metal ones in order to reduce weight and cost by using resins made of light and strong polymeric materials such as nylon. There is a tendency to use manufactured products. Since it is difficult to mold this resin surge tank in one piece, it is currently manufactured by a manufacturing method in which divided pieces are joined and integrated. On this occasion,
Generally, various welding methods can be applied to join resin materials, but according to the research results of the present inventors, vibration welding and hot plate welding are useful and practical for joining this type of tank. Guessed. More specifically, since vibration welding has the disadvantage of generating burrs that easily fall off on the joint surface, hot plate welding is considered the most desirable joining method.
この熱板溶着は、接合しようとする両分割片の

いうプロセスによるものである。 This hot plate welding involves placing hot plates that have been heated to several hundred degrees on the welding surfaces of the two pieces to be joined, facing each other with the hot plates in between, and each welding surface is heated by radiant heat from the hot plates, resulting in half of the welding surfaces being heated to several hundred degrees. Once they have softened into a molten state, they are brought together under pressure and joined together with an appropriate crimping margin.
［発明が解決しようとする問題点］
ところが、この熱板溶着により接合したサージ

用途に適用する場合には強度不足を否めない。[Problems to be Solved by the Invention] However, even with surge tanks joined by hot plate welding, there is a problem that the strength of the joint is still lacking, especially when the surge tank has a high internal pressure such as a turbocharger specification engine. When applied to surge tank applications, it cannot be denied that the strength is insufficient.

分子的な接合を妨げるものとなる。 The causes of such a decrease in strength at the joint are considered to be as follows. That is, at the stage of heating the welding surface, a portion of the resin material forming the tank material is first carbonized, and during crimping, the carbonized material is interposed in a layer as a foreign material on the joint surface. To schematically show this, as shown in Fig. 6, softened layers (molten resin material) A, A are formed near the welding surfaces s, s of both divided pieces (resin material) in the heated state before crimping. Furthermore, the surface side portion is transformed into carbonized layers C and C by heating. From this state, the flat welding surfaces s, s of the divided pieces
When they are pressed together, as shown in Fig. 7, the carbonized layers C, C on the surface are mostly pushed out to the inner and outer surfaces to form burrs B, B together with the molten resin materials A, A. Some parts are divided as they are,
It is interposed in the form of a thin film between the welding surfaces s and s of the two, and prevents molecular bonding between the two.

An object of the present invention is to provide an improved manufacturing method using hot plate welding that can reliably prevent the problem of reduced joint strength due to the presence of a carbide layer on the joint surfaces of a resin surge tank by a simple means.

になる。[Function] If the welding surfaces of the divided pieces have a predetermined slope as described above, when the welding surfaces are pressed together after heating, the carbonized layer formed on the surface will be removed by excess molten resin material. At the same time, the material is strongly extruded along the inclined surface, thereby eliminating the presence of a harmful carbonized layer at the bonding surface. That is, first, when the welding surfaces face each other and are in contact with each other, a space having a wedge-shaped cross section is created between the two by the inclined surfaces formed on one or both sides thereof. Then, when the welding surfaces are pressurized to increase the crimping margin between the two divided pieces, the molten resin material with the carbonized layer attached to the surface is pooled in this wedge-shaped space, and the molten resin material is removed from the pressure that closes the wedge-shaped space. The pressing force generated by the wedge effect sequentially pushes the material into and out of the wall thickness. Therefore, after the two divided pieces are crimped to the required crimping distance, a high-strength joint structure will be realized in which the healthy resin materials from which the carbonized layer has been removed are directly welded to each other on the joining surfaces of the two pieces. Become.

That is, in this case,
The surge tank T is a pressure-resistant type installed in a turbo engine, and the upper lid piece that connects the two air supply pipes d 1 and d 2 and the main center piece that forms the remaining main body are welded together.

During molding or by processing after molding, an inclined surface is formed in advance on the hot plate H, making a certain slight inclination angle θ, which descends from the thicker inner side to the thicker outer side. Furthermore, the flanges F 1 and F 2 of both of these divided pieces are provided with a pair of annular recesses a and a at opposing portions near their outer peripheries, and furthermore, the recesses a and a are closed at the outer periphery ends thereof, respectively.

接溶着する接合構造が得られる。 Therefore, the divided pieces having the flange portions F 1 and F 2 are welded together according to the normal hot plate welding process, and as shown in FIG. 1, the welding surfaces s 1 , undergoes heating of s 2 . Then, in the state immediately before crimping after heating for a predetermined time, softened layers A and A are formed at the required depth in the thick parts near the welding surfaces s 1 and s 2 , respectively, as shown in the same figure.
After all, carbonized layers C and C are generated on the surface side. Remove the hot plate H from this state, align the flange parts F 1 and F 2 of both divided pieces, and
As shown in the figure, both are pressed together with a predetermined pressure P. However, each welding surface that collides with
Since s 1 and s 2 are formed with outwardly downward slopes, a space W having a wedge-shaped cross section that expands outward is created between them when they are in contact with each other. When the crimping margin of the flanges F 1 and F 2 increases due to the pressurizing force P, the excess molten resin material A with the carbonized layer C attached to the surface is pulled into this wedge-shaped space W, and the wedge-shaped space W is closed. As it progresses, it acts to forcibly expel the fluid inside it to the outside. That is, due to the wedge effect, a force F is applied to this wedge-shaped space W, which strongly pushes the fluid contained therein outward as a component of the pressurizing force P from the inclined surfaces on both sides of the space W, so that the carbonized layer C is The mixed molten resin material A is sequentially extruded along the slope. Then, as shown in Figure 3, a predetermined crimping distance δ (at least 0.2 mm or more preferably 0.5 mm) is applied.
In the bonded state where crimping has been completed up to (above), healthy resin materials from which the carbonized layers C, C attached to the original welding surfaces s 1 and s 2 have been removed, are directly welded to the bonding surface S of the two. A bonded structure is obtained.

損なうこともない。 According to this method, a portion of the molten resin material A leaks inward along with the carbonized layer C during the crimping process, forming a small burr Bi on the inner surface of the tank, but most of it leaks outward as described above. It is discharged in the opposite direction.
Then, the fluid (A
+C) is stored in the space created by combining the annular recesses a and a of the flanges F 1 and F 2 , and a burr is formed inside the space.
Bo is formed without adding extra thickness to the joint.
Moreover, it is not closed by the ribs b, b on the outer periphery and does not spoil the appearance.

なる。 As described above, according to the manufacturing method according to the present invention,
By forming predetermined slopes on the welding surfaces s 1 and s 2 of the divided pieces and crimping them together with an appropriate crimping margin, carbonized layers C and C are produced on the surfaces when heated by the hot plate. Finally, a carbonized layer C is formed from the joint surface S.
It can be effectively eliminated. In other words, the intervening carbonized layer C, which was a factor in reducing the bonding strength of this type of manufacturing method, is removed, and the healthy resin materials can be directly molecularly bonded to each other and exhibit high strength.

Although both of the divided pieces are provided with inclined surfaces, substantially the same effect can be obtained even if only one of them is formed. The direction of inclination of the inclined surface may be either thick or thin depending on the conditions and application of the surge tank.
