Abstract

PURPOSE:To utilize a boss material effectively so as to crimp at a high speed by inserting a boss protruding from a thermoplastic plastic member into a hole of other member and enlarging the external diameter of the boss, and forming an expanding head on its tip. CONSTITUTION:A hollow boss 13 of a member 12 is inserted into a through hole 11 of a member 10 so as to butt the members 12 and 10 against each other. Thereafter, an axial core of a crimping chip 1 is aligned with an axial core of the boss 13. When a heated core bar 2 is made to descend and pushed into the hollow of the hollow boss 13, the tip of the hollow boss is heated and softened, the tip of the hollow boss 13 is enlarged by a conical face of a protrusion 4 in accordance with the descent of the core bar 2, and the central part of the external diameter of the hollow boss 13 is butted against the end edge of the through hole 11 during a period that the core bar 2 descends till a predetermined position. Successively, an outer cylinder 3 is made to descend and a bottom face of a groove 5 formed on the outer cylinder 3 is butted and pressed against the tip of the hollow boss 13 which is overhanging from the outer peripheral face of the core bar 2, so that an expanding part is molded in a cavity to be formed by closures of the groove 5 and surface of the member 10.

いる．2. Description of the Related Art A plurality of bosses are projected on a surface of a thermoplastic member, the bosses are inserted into through holes provided in other members and projected to the opposite side, and the bosses are heated and melted to be riveted. A method of crimping a plastic member to another member by molding it into a circular head is conventionally known, but as a conventional method of this kind, it is practically 5-18131.

めである．By the way, the relationship between the outer diameter of the boss crimped by the conventional method and the inner diameter of the through hole through which the boss is inserted is generally such that the inner diameter of the through hole is smaller than the outer diameter of the boss.
The size is increased by 5 to 2.0 mm. The reason for this is that even if the molding accuracy such as the pitch of a plurality of bosses or the pitch of a through hole varies by the above-mentioned numerical value, a plurality of bosses can be inserted into a plurality of through holes corresponding to this boss.

The vertically movable crimping tip 1 is composed of a heated core rod 2 and an outer cylinder 3 which is closely attached to the outer peripheral surface of the core rod 2 and is heated. The tip surface of the outer cylinder 3 is appropriately protruded from the tip surface of the outer cylinder 3, and the outer diameter of the outer cylinder 3 is gradually increased in a conical shape until it reaches the same plane. The protrusion 4 is formed to have a diameter dimension D, and the D dimension is appropriately larger than the inner diameter dimension of the hollow boss 13. In addition, a semicircular groove 5 is formed around the protrusion 4 in the core rod 2 and the outer cylinder 3 so as to surround it.

2- (a), the hollow boss 13 is preliminarily softened by hot air from a hot air generator (not shown), and then the caulking tip 1 and the hollow boss 13 have the same axial core as in the first embodiment. When the caulking tip 1 is lowered by aligning the
As shown in (b), the protrusion 4 enters the hollow portion of the boss 13 and the conical surface of the protrusion 4 enters the inside of the hollow portion of the hollow boss 13, and the tip portion of the hollow boss 13 is the same as in the first embodiment. Is enlarged and the outer diameter center of the hollow boss 13 is brought into contact with the edge of the through hole 11, while the enlarged tip of the boss 13 is housed in the groove 5 and the tip of the caulking tip 1 is of the member 10. When it comes into contact with the surface, it fills up in the void that is closed by the groove 5 and the surface of the member 10 to form a bulge. After that, when properly cooled and the caulking tip 1 is raised, the two members are joined as shown in FIG. 2- (c).

発振器が必要に成るが熱風発生装置は不要になる．The tip of the ultrasonic horn for melting the boss by applying ultrasonic vibration to the boss by the ultrasonic welding method is similar to the crimping tip shape of this embodiment, and the projection 4 is formed in the hollow boss 13 in the same manner as above. Even when the ultrasonic horn is ultrasonically vibrated by pressing on the tip, the outer diameter of the boss 13 is gradually expanded by melting and softening from the tip of the hollow boss 13 and the boss 13 of the boss 13 is expanded. After the central portion of the outer diameter is brought into contact with the edge of the through hole 11, a bulging portion formed in the shape of the groove 5 is formed. In this case, an ultrasonic oscillator is required, but a hot air generator is not needed.

尖らすと速くかしめることができる．The heated caulking tip 1 of the second embodiment, or the ultrasonic horn tip having the same shape as that of the second embodiment, is as shown in FIG. It can also be applied to the solid boss 14. At this time, when the tip of the protrusion 4 is pressed against the tip of the boss 14, the tip of the boss 14 is softened and melted, and a part of this is discharged along the conical surface and accommodated in the groove 5 while the boss 14 is outside. The diameter is gradually enlarged, and the bulged portion in the shape of the rear groove 5 is formed by contacting the outer diameter central portion of the boss 14 with the edge of the through hole 11 as in the previous embodiment. When crimping the solid boss with an ultrasonic horn, it can be crimped quickly by sharpening the tip as shown in Fig. 3- (b).

部が成形され二つの部品が結合される．As described above, according to the method and apparatus for crimping a plastic member according to the present invention, a conical protrusion protruding from the tip surface is formed at the center of the tip of the crimp tip. For example, if the conical protrusion of the caulking tip is pressed into the end of a hollow boss whose end is open, the outer diameter of this boss is enlarged in a conical shape and the outer peripheral surface of the boss is located at the upper edge of the through hole. The central part is abutted. Therefore, even if the tip portion of the boss is subsequently melted and caulked, the molten boss material does not flow into the gap between the boss and the through hole, the bulging head is formed, and the two parts are joined together.

た効果を奏する．As described above, since all the molten boss materials are used for forming the bulging head, the boss length can be shortened. Therefore, only the length of the boss that corresponds to the bulging head needs to be caulked, and the caulking time can be extremely shortened, which is a practically excellent effect.
