Problems solved by technology

However, in the conventional ultrasonic vibration (vibration direction is a single longitudinal) extrusion process, there is severe sliding friction between the tool and the processing surface, the resulting mechanical wear will greatly reduce the service life of the tool, and the quality of extrusion processing will also decrease. Rapid decline with rapid tool wear
The processing cost is greatly increased due to the short tool life, which limits the popularization and application of vibration extrusion processing technology in the field of finishing processing

Abstract

The invention discloses an ultraphonic elliptical vibration and extrusion processing device based on a double-excitation longitudinal bending elliptical energy converter, comprising a shell assembly, a vibration assembly, a sliding assembly and a pressure assembly, wherein the sliding assembly is sleeved on the excircle surface of the vibration assembly; the pressure assembly is arranged on the tail part of the vibration assembly; and the assembled vibration assembly, the sliding assembly and the pressure assembly are arranged in the shell assembly. The structure of the ultraphonic elliptical vibration and extrusion processing device is designed by combining a flexible extrusion requirement with a langevin energy converter principle, when the ultraphonic elliptical vibration and extrusion processing device is adopted to carry out extrusion processing, the double-excitation longitudinal bending elliptical energy converter of the ultraphonic elliptical vibration and extrusion processing device can drive a cutter to cautiously take longitudinal bending elliptical vibration, tracks of the longitudinal bending elliptical vibration are tangent with tracks of the turning motion of a workpiece and is reverse to the turning direction of the workpiece, when the turning speed of the longitudinal bending elliptical vibration is equal or approximately equal to the turning speed of the workpiece, the cutter is equivalent to make pure rolling on the surface of the workpiece so that relative sliding between the cutter and the processing surface disappears, and the mechanical abrasion caused by sliding friction is effectively prevented, and the purpose of prolonging the service life of the cutter is achieved.

Description

technical field [0001] The invention relates to an extrusion processing device, more particularly, to an ultrasonic elliptical vibration extrusion processing device based on a dual-excitation longitudinal bending elliptical transducer. Background technique [0002] The ultrasonic vibration transducer is the most important part of the ultrasonic vibration processing system, and its design effect directly affects the processing quality. In general, the transducer itself has three vibration forms: longitudinal vibration, bending vibration and torsional vibration. When the two vibration forms are combined with a certain phase difference, elliptical vibration can be obtained. Most of the longitudinal bending elliptical vibration transducers currently used use a single-excited asymmetric structure horn to obtain the elliptical vibration form. However, the controllability of the elliptical vibration obtained through this transducer is poor, which is not conducive to better processi...
