ULTRASONIC HORIZONTAL VIBRATION REED

PURPOSE:To efficiently convert a vertical vibration into a horizontal vibration, by forming an input part of uniform section, which engages an ultrasonic vertical vibration horn, in a thickness larger than that of an output part, having a tool, in the case of an ultrasonic horizontal vibration reed used for ultrasonic vibration cutting or the like. CONSTITUTION:A horizontal vibration reed 7 comprises an input part 5 and an output part 6. And a vertical vibration horn 1 is firmly mounted by a bolt 3 to the input part 5 in the vicinity of a horizontal vibration displacement loop. Here ratio of second moment of area to a radius of rotation in the output part 6 is selected smaller than the ratio of second moment area to a distance from a neutral plane to a surface layer in the input part 5. In this way, a connection part with a vertical vibration horn 1, generating no heat, enables a vertical vibration to be efficiently converted into a horizontal vibration. As a result, the horizontal vibration reed 7 can render services to a field such as ultrasonic vibration cutting or welding removably connecting the vertical vibration horn and the horizontal vibration reed.
