Title:
TOOL HORN FOR ONE WAVELENGTH RESONANCE TYPE TORSIONAL OSCILLATION
Document Type and Number:
Japanese Patent JP3124787
Kind Code:
B2
Abstract:
PURPOSE: To expand a working area by forming the horn main body with a driving side horn part and a radiation side horn part, and also forming the radiation side horn part with a cylindrical outside horn and a rod-shaped inside horn, and further forming an axially extending hole in the inside horn.
CONSTITUTION: The tool horn for one wavelength resonation type torsional oscillation intended to be used for ultrasonic fusing of plastic, punching work of metal or the like is equipped with a horn main body 1 comprising a driving side horn part 4 in a driving surface 2 side and a radiation side horn part 5 in a radiation surface 3 side. The radiation side horn part 5 is also made into a double structure with a cylindrical outside born 6 and a rod-shaped inside horn 7, and in the central part of the inside horn 7, a hole axially extending from the radiation surface 5 is bored. The driving side horn part 4 and inside horn 7 have axially directional dimensions L2, L3 set at a nearly half value of the frequency 2 of supersonic torsional oscillation F, and also have a depth L4 of the hole 9 set at a value of about λ/4, thereby enabling the enlargement ratio to be made maximum in the displacement of a radiation surface 3b.
