<p>PURPOSE:To surely join a plate body without accompanying the inconvenience of a dust, burr, etc., spoiling its external appearance by filling up a thermosetting resin between two plate bodies and curing the thermosetting resin by giving ultrasonic vertical vibration with pressing the plate body. CONSTITUTION:A piston 24 is driven with the actuation of an air cylinder 22, a horn 30 is pressed via an ultrasonic wave generator 26 and the folded end part 12a of an outer side metal plate body 12 is pressed. The ultrasonic wave generator 26 is actuated simultaneously with this pressurization, exciting the horn 30 in the vertical direction. The ultrasonic wave is thus propagated effectively to the thermosetting resin 14 of the hem inner part through the plate body end part 12a, the resin 14 is cured by being heated and adhered to both metal plate body end parts 10a, 12a. Consequently both metal plate body end parts 10a, 12a are strongly joined with the adhesion force of the cured resin 14 without receiving any deformation nor external wound.</p> |
