Description
Technical Field

Background
The ultrasonic vibration assisted forming process is one of the leading research directions in the field of metal part micro-plastic forming at present. In the ultrasonic vibration assisted micro-plastic forming process, an ultrasonic system generates ultrasonic frequency mechanical vibration through an ultrasonic vibration power supply, an ultrasonic transducer and an ultrasonic amplitude transformer, increases the amplitude of the vibration, and transmits the vibration to a micro-plastic forming tool or a processed workpiece to generate high-frequency resonance, thereby realizing the ultrasonic vibration assisted micro-plastic forming process. The ultrasonic vibration assisted micro-plastic forming process reported in the existing research literature mainly comprises ultrasonic micro-stretching, ultrasonic micro-extrusion, ultrasonic micro-imprinting, ultrasonic micro-upsetting, ultrasonic micro-bending, ultrasonic micro-blanking and the like.
ECAP is a typical process for preparing ultrafine crystals by large plastic deformation, and is called equal channel angular pressing. A schematic diagram of a conventional ECAP apparatus is shown in fig. 7. The material is subjected to strong shear deformation at the corners of the die, while the cross-sectional dimensions remain substantially unchanged, so that repeated extrusion is possible, accumulating a large amount of strain, mainly for refining the grain size of the metallic material.
In the study of the existing ultrasonic vibration assisted ECAP forming process, an ultrasonic vibration system consisting of an ultrasonic transducer and an ultrasonic amplitude transformer is generally arranged along the vertical extrusion direction, the tail end of the ultrasonic amplitude transformer is connected with an ECAP extrusion tool into a whole and realizes the high-frequency vibration in the vertical direction or the horizontal direction, and because the vertically placed ultrasonic equipment needs a larger installation space, the applied ultrasonic vibration can only be applied to the extrusion tool, the extrusion direction can only be in a single vertical direction or the horizontal direction, and the composite ultrasonic extrusion in multiple directions can not be realized simultaneously, so that the installation in the prior art is not facilitated, and the applied ultrasonic effect does not reach the best. In addition, in the currently reported ultrasonic vibration-assisted ECAP process, a single-direction auxiliary ultrasonic vibration is mainly applied to the formed workpiece or the ECAP tool, and no research report on simultaneously applying multi-direction composite ultrasonic vibration to the formed workpiece and the ECAP tool exists.
The continuous ECAP is a processing method for reducing extrusion passes by increasing equal channel angle channels required by extrusion on the basis of common ECAP, the schematic diagram of the continuous ECAP device is shown in FIG. 8, and the continuous ECAP device also has the problems that the extrusion direction is single, the composite ultrasonic extrusion in multiple directions cannot be realized simultaneously, and the like.
