    摘要: A riveting apparatus includes a hot air pipe; a connection pipe coupled to the hot air pipe; a forming tool having a configuration in which peripheral and center portions project downward and portions existing therebetween are curved upward, defined with discharge holes which extend in axial and radial directions, and coupled to a lower end of the connection pipe so that hot air having passed through the connection pipe can be discharged through the discharge holes to heat an end of a rivet to thereby allow the forming tool to form the end of the rivet into the shape of a head; a moving unit coupled to the hot air pipe or the connection pipe to move the forming tool upward and downward; and a guide surrounding the forming tool so that hot air discharged through the discharge holes can be directed toward the end of the rivet.

    摘要: Die Vorrichtung zur Verbindung von Gegenständen mittels eines plastisch verformbaren Verbindungskörpers umfasst einen Formstempel (4), eine den Formstempel eng umgebende Strömungsbegrenzungswand (5) und eine Gaszuführungsleitung (6), durch die ein gasförmiges Medium in den Spalt zwischen dem Formstempel (4) und die Strömungsbegrenzung (5) einführbar ist. Der Formstempel (4) weist eine Heizpatrone (8) auf, mit der das untere Ende des Formstempels erhitzbar ist. An der Außenseite dieses Formstempels sind Wärmeübertragungsrippen (9) vorgesehen, die zur Erwärmung des zugeführten gasförmigen Mediums dienen, das am unteren Ende der Strömungsbegrenzung austritt, um eine Strömung um einen plastisch verformbaren Verbindungskörper (3) zu erzeugen, damit dieser für den Verformungsvorgang gleichmäßig erhitzt wird. Der Verbindungskörper 3 ist an einem Teil (2) mit angeformt und greift durch eine Bohrung eines zweiten Teiles (1), welches mit dem ersten Teil zu verbinden ist. Mittels des Formstempels (4) wird ein Nietkopf (3a) an dem Verbindungskörper (3) angeformt.

    摘要: An ultrasonic welding apparatus (1) includes an ultrasonic horn (3) holding a resin stud (7) having a flange (5) and an engagement shank (6), and a body (2) to bring the flange of the stud (7) held by the ultrasonic horn into contact with a workpiece, so that the flange (5) is ultrasonic-welded onto the workpiece. The ultrasonic welding apparatus further includes a stud receiving member (10) to receive the resin stud (7) in the manner that the flange is advanced ahead from a feeding tube (9); and a moving mechanism (a first arm (19), a first arm cylinder (21), a second arm (23), a second arm cylinder (25), and the like) to move the stud receiving member (10) to a position below the ultrasonic horn (3). The moving mechanism can move the engagement shank (6) of the resin stud (7) in the stud receiving member (10) to a position adjacent to a housing portion (30) of the ultrasonic horn (3). The stud receiving member is formed with a recess (11) to seat the flange (5) therein. Negative pressure is applied to the seating recess (11) to vacuum-tack the flange. The rim of the seating recess is formed in a mortar configuration so that the flange can be positioned in the center of the seating recess. This provides an ultrasonic welding apparatus of a simple structure which allows a resin fastener to be automatically loaded into an ultrasonic horn, and to provide an ultrasonic welding method of high operational efficiency.

    摘要: A method of joining the two thermoplastic parts (20,30) which may be a casing (41, 42) for electronics as example, uses an electric heating element wire (20) which is seated in channels (44) of the bottom casing (41). The casing cover (42) has a rim which presses the wire (20) into the channel (44) when the parts are assembled. Electric current is applied to the ends (21) of the element wire (20) using electrodes (10) which are pressed into contact with each end (21) of the wire (20) to heat the wire and fuse the plastic parts together at the joint after which the electrodes are withdrawn. The electrode (10) has a central axial bore through which cooling gas may flow fed from a supply via pipe (34). The cooling gas prevents the ends (21) of the wire (20) from heating up to melt or spoil the support base (45) or adjacent parts and to prevent the electrodes sinking into the base 45.
