Abstract

PURPOSE:To join a plurality of plastic members with strength higher than a certain value at all times by a method wherein a plurality of the plastic members are piled up and pinched between a pair of dies and a pair of punches so as to soften and turn the plastic members in fluid state by repeatedly deforming the latter pair under vibrating state and to push a joining member, on the outer periphery or inner side surface of which engaging parts are provided, in the plastic members under fluid state. CONSTITUTION:Plastic members 6 to be joined under piled-up state are seated onto a lower die 2. A metal pin 5, which acts as a joining member and on the outer peripheral surface of which recessed engaging parts 9 are provided, is brought into contact with the plastic members 6 to be joined under the state being guided with an upper die 1 and an upper punch 3. By repeatedly deforming the plastic members 6 through the synchronous axial vibrations of the upper punch 3 and of the lower punch 4, which are developed by the actuation of a servo cylinder supported on a main body, heat is generated in the deformed region of the plastic members, to which vibration is applied. When the plastic members in their deformed region contacting the pin 5 become fully softened, the pin is pushed in the members by lowering the upper punch 3. When the pin is pushed in, the plastic displaced by the pin flows in a cavity 7 and at the same time fills the engaging parts 7 of the pin 5. The joining of a plurality of the plastic members is completed by the imbedded pin 5.

Then, due to the heat, only a portion of the plastic material becomes soft and fluid, and this portion has a high deformability. When a joining member (for example, a bottle) is pushed into such a portion, the plastic material flows into a convex or concave locking portion formed on the outer peripheral surface or inner surface of the joining member and fills the locking portion. Cool and solidify in this state. The fixed plastic material flowing into the locking portion works together with the locking portion to generate a mechanical restraining force, and the plurality of plastic materials are firmly joined.
