- the ultrasonic horn 1 converges ultrasonic waves generated by an ultrasonic transducer (not shown) and generates tip vibration of ultrasonic waves.
- Ultrasonic horn 1 and punch 2 are not fixed. Therefore, when vibration is applied to the rear end (head 2 a) of the punch 2 by the ultrasonic horn 1, the punch 2 is splashed and travels away from the ultrasonic horn 1.
- the punch 2 has a head 2 a to which vibration is applied by the ultrasonic horn 1, a force portion 2 b which contacts the work W to apply a drilling force, the head 2 a and a force portion And a torso shaft 2c for connecting with 2b.
- the punch 2 is held in a floating state at a predetermined position (the position shown in FIG. 2A) by an elastic body 4 provided between the head portion 2a and the guide bush 3 to scoop!
- the head 2 a of the punch 2 has an arc-shaped surface in contact with the ultrasonic horn 1.
- the cross-sectional shape of the tip of the processed portion 2a of the punch 2 can be any shape such as a circle, a wing, a quadrilateral, a triangle or an oval.
- the elastic body 4 has a restoring force to at least a position contacting the ultrasonic horn 1, for example, a predetermined position shown in FIG. 2A, and the punch 2 displaced by the predetermined position force by this restoring force is set to a predetermined position. It will be returned to
- the elastic body 4 is constituted of, for example, a spring (a leaf spring, a coil spring, a mainspring, an air spring, a rubber), a damper, a combination thereof, or the like.
- the die 5 holds the work W together with the punch 2.
- the die 5 has a hole 5a for drilling corresponding to the processed portion 2b of the punch 2 and a tapered hole 5b connected to the hole 5a for drilling.
- the tapered hole 5b is a hole that expands in the drilling direction, that is, from the connecting portion with the drilling hole 5a to the lower side (open side) of the die 5.
- the tapered holes 5b allow the chips generated after processing to be easily discharged downward, and the chips clog the holes.
- the guide bush 3 In order to restrict the advancing direction of the punch 2, the guide bush 3 has a cylindrical guide hole 3a in which the head 2a of the punch 2 slides on the inner side, and the processed portion 2b of the punch 2 slides on the inner side. And a movable cylindrical guide hole 3b.
- the punch 2 is restricted by the guide holes 3a and 3b from moving in the axial direction of the body shaft 2c.
- the above-mentioned elastic body 4 is provided between the lower end of the guide hole 3 a and the head 2 a of the punch 2.
- the diameter of the head 2a of the punch 2, the body shaft 2c, the processed portion 2b, and the guide holes 3a and 3b of the guide bush 3 is reduced in diameter in the direction in which the punch 2 is drilled. V as a shape.
- the diameter of the largest diameter is adjusted by fitting the head 2a of the punch 2 and the guide hole 3a to provide a play in the portion 2b and the guide hole 3b.
- the reason for providing play in the portion of the processing portion 2b and the guide hole 3b is that the tip of the processing portion 2b is excessively stressed during processing, causing bending or bending. This is to prevent damage due to deformation such as buckling.
