The invention relates to a multi-hole rectangular hexahedral ultrasonic amplitude transformer. The body of the ultrasonic amplitude transformer is a rectangular hexahedron (1), the upper surface of the rectangular hexahedron (1) is a radiating surface (2), and a plurality of evenly-distributed vertical cylindrical through holes (5) which are equal in diameter are formed in the rectangular hexahedron (1). The ultrasonic vibration characteristics of the rectangular hexahedron are changed and controlled through the vertical cylindrical through holes which are evenly distributed in the rectangular hexahedron, so that the supersonic vibration, inputted through an ultrasonic transducer and an ultrasonic horn, in the horizontal direction is transformed to the supersonic vibration in the vertical direction, and the vertical directional amplitudes which are uniform in size are obtained in the center area of the radiating surface of the rectangular hexahedron; therefore the multi-hole rectangular hexahedral ultrasonic amplitude transformer is beneficial to loading platy workpieces with any shapes and any sizes for achieving auxiliary ultrasonic vibration in the vertical direction.
Description
technical field [0001] The invention relates to the technical field of ultrasonic-assisted forming processing, in particular to a porous rectangular hexahedron ultrasonic horn. Background technique [0002] Ultrasonic-assisted forming of difficult-to-machine materials is one of the key issues in the current research on machining technology. In ultrasonic assisted forming processing, the ultrasonic system generates ultrasonic mechanical vibration through ultrasonic power supply, ultrasonic transducer and ultrasonic horn (or horn) and increases the amplitude of the vibration, which is transmitted to the processing tool or the workpiece to be processed. Make it generate high-frequency resonance, so as to realize ultrasonic-assisted forming processing. At present, in the ultrasonic assisted forming process, the ultrasonic vibration is mainly superimposed on the processing tool, and there are few processes based on the assisted ultrasonic vibration of the processed workpiece.
