題があった。(Prior Art) Many methods are known for attaching members such as pins to plastics or their composite materials, such as insert processing using injection molding, and fusion bonding by inserting high-frequency heated metal parts into pilot holes. There is a way to do it. However, although the former is suitable for mass production, it is not suitable for high-mix, low-volume production because it uses a mold, and the mold is also complicated, and the latter requires pilot hole machining by injection molding in advance, and requires considerable heat and requires a long processing cycle. There are disadvantages such as long length, and there are also insert methods using ultrasonic machining and methods using caulking press-fitting, but the former still requires a prepared hole and requires a large device, making it suitable for mass production, while the latter is less reliable. Adhesion is often used as a reliable and easy method, but it is complicated and causes problems in terms of appearance and work, such as the resin protruding.

It is held between a pair of dies and a pair of punches, the pair of punches or one pair of the pair of dies is fixed to the main body, and the other pair is repeatedly displaced in a vibrating state, and the area to which the vibration is applied is generating heat to soften the material and bring it into a fluid state, and further displacing the other pair of the punches or dies so as to cause the material in the fluid state to flow around the member including the locking portion of the member. This is a method for joining parts to plastics or composite materials thereof. That is, by repeatedly deforming the same region of the material held in contact with the member between the die and punch, heat is generated in the deformed region. The heat causes only a portion of the material to soften and flow, creating an area with high deformability.

としたものである。The applicant named the process of forming by utilizing this deformability as "localized thermoforming." Therefore, this method can be regarded as a new processing form that combines cold plastic processing and thermoforming. Note that temperature may be applied to the material. The method of the present invention applies the technique of "localized thermoforming" to a bonding technique that mechanically and reliably attaches small members made of various materials, such as pins, to a portion of a thermoplastic plastic or its composite material.

In the finished product, the recessed locking portion (5) was physically locked by the material (6), achieving a strong connection between the material (6) and the metal pin (5). Furthermore, unlike conventional products, parts are not simply inserted into holes, but the area around the locking part, such as the fluid molded part formed by the cavity (7), further expands the support part, stably achieving even higher strength. can. Moreover, since the method used here is based on mechanical deformation without using heating media or adhesives, it is a safe, simple, and inexpensive joining method.

It is now possible to join parts to plastics or their composite materials. In other words, according to the present invention, in addition to being a joining mechanism that physically locks, it is possible to stably achieve considerably high strength because the fluid forming part further expands the support area instead of simply inserting the member into the hole. became. Moreover, the method used here is
Since it is based on mechanical deformation without using a heating medium or adhesive, it has the advantage of being able to realize a safe and simple joining form. Moreover, expensive and highly precise members can be firmly and reliably joined. To explain in more detail, in addition to supporting the outer periphery of the pin in the bottle stand and member insert by the combination of the plate thickness and the cavity depth, it is also mechanically locked against forces in the pulling and pushing directions. Therefore, it is necessarily very strong. Furthermore, there is an advantage that the shape of the member can be made into any shape to some extent, and the shape of the locking portion can also be changed. Therefore, for example, the contact parts of a switch can be easily attached to the surface of a plastic material. Feed f'L7j in the punching direction, the workpiece is clamped by a pair of punches and fixed to the main body, conversely, a pair of upper and lower dies are movably supported relative to the main body, and the servo cylinder controls the vibration and feed.
