れている。Prior Art Conventionally, this type of processing machine, widely known as an ultrasonic plastic welder, uses a processing horn that is ultrasonically vibrated to press a processing horn placed on a support member against a workpiece. Therefore, the workpiece is subjected to ultrasonic processing such as welding and insert molding based on the frictional heat generated in the workpiece due to the ultrasonic vibration. is already provided.

もあつた。 However, in the conventional apparatus described above, not only is the ultrasonic vibrator for generating ultrasonic vibrations expensive, but also the shape of the processing horn must be designed each time according to the ultrasonic vibration frequency, processing content, etc. However, if the workpiece is made of a soft material such as non-woven fabric, sufficient ultrasonic vibration cannot be applied to the workpiece. In some cases, sufficient processing could not be performed because sufficient frictional heat could not be generated.

つた。 In addition to the above-mentioned ultrasonic plastic welder, this type of processing machine is also used, for example, by pressing a preheated metal mold against a workpiece placed on a support member. Various devices have been proposed that are capable of molding, welding workpieces together, and inserting various parts into workpieces. Since it is a device that applies heat, it not only requires loss time to preheat at the start of work, but also has problems such as extremely poor thermal efficiency as the heat escapes to the surroundings. All of them had little practicality.

When the start switch 29 is pressed after the workpieces W 1 and W 2 are placed on the plate 2, the direction control valve 13 is switched to the first position I, and the piston rod 6 is moved to the movable position. It is moved downward together with the frame body 7, the presser metal fitting support member 8, the presser metal fitting 9, etc. At this time, as the presser metal fitting 9 descends, the first and second workpieces placed on the plate 2
The upper surface of the second workpiece W 2 of W 1 and W 2 is brought into contact with the machined surface 9c of each protrusion 9a, 9a and convex part 9b formed on the presser metal fitting 9, and the machined surface 9c
The pressure applied to the electromagnetic coil 4 is increased, and the inverter 30 is driven based on a control signal from the control circuit 33 to supply alternating current to the electromagnetic coil 4. As the alternating current is supplied, a magnetic flux is generated around the electromagnetic coil 4, and the generated magnetic flux is alternately passed through the presser metal fitting 9 that has been lowered to a position close to the coil 4, The magnetic flux generates eddy current loss in the presser metal fitting 9, and the presser metal fitting 9 immediately generates heat. As the presser fitting 9 generates heat, each of the protrusions 9a and convex portions 9
The temperature of the workpiece W 2 brought into contact with the workpiece W 2 increases and melts in its periphery, and as a result, the presser metal fitting 9 is lowered to the extent that the first workpiece W2 is melted. When it is lowered, the pressure switch 27 provided on the rod side inlet 5b side is activated. Immediately after the pressure switch 27 is activated, the drive of the inverter 30 is stopped and the presser metal fitting 9 is held for a sufficient time (0.1 to 0.2 seconds) to cool and solidify the melted parts of the first and second workpieces.
After that, the directional control valve drive circuit 16 is activated, the directional control valve 13 is switched to the second position, and the piston rod 6 is moved to the presser fitting 9.

a, an example in which a protrusion 9b is formed and the protrusion 9a and protrusion 9b are inserted into the second workpiece W2 to a position approaching the first workpiece W1 to weld them together. However, for example, if an adhesive such as a thermoplastic adhesive film is interposed between the two workpieces in advance, the protrusion or protrusion may not necessarily be provided on the presser metal fitting 9. It goes without saying that the part or convex part does not have to penetrate into the workpiece.
