Ultrasonic cutting and polishing machining system

Abstract

The invention discloses an ultrasonic cutting and polishing machining system. The ultrasonic cutting and polishing machining system comprises an ultrasonic transducer, an amplitude transformer, and awiper blade cutter, wherein the front end of the ultrasonic transducer is tightly and reliably connected with the rear end of the amplitude transformer; the ultrasonic transducer is connected with anultrasonic power supply through a lead; a flange plate is arranged at the vibration displacement node position of the amplitude transformer; the flange plate is connected with a B-axis rotary tool rest through a supporting plate; and the wiper blade cutter is tightly and reliably connected with the front end of the amplitude transformer. According to the ultrasonic cutting and polishing machiningsystem, ultrasonic high-frequency vibration in the feeding direction of the cutter can improve the action length of a wiper blade, reduce the generation of secondary tool marks on the machining surface of the wiper blade, and improve the quality of the machined surface; due to the cleaning effect of the ultrasonic vibration, it is difficult to generate chip accumulation at the wiper edge, and thequality of the machined surface is better guaranteed; the ultrasonic vibration changes the contact state and action mechanism between the cutting edge and the wiper edge and the material to be machined, reduces the cutting force and the cutting temperature, and improves the surface quality after the cutting edge is processed, and thus the quality of the machined surface is further improved due tothe combined action of the polishing edge and the ultrasonic vibration.

Description

technical field [0001] The invention relates to the field of precision cutting and processing of metal materials, in particular to an ultrasonic cutting and smoothing processing system. Background technique [0002] After cutting metal materials such as carbon steel and alloy steel, grinding is usually required to obtain better cutting surface quality, but the efficiency of grinding is relatively low, especially for non-ferrous metals and their alloys. The material cannot be ground to obtain a better quality of the cut surface due to its low hardness. In order to solve the problem of efficient machining of high-quality surfaces of metal materials, the designers propose to use cutting tools with wiper edges to realize cutting instead of grinding, which increases the impact resistance of the tool tip, reduces the surface roughness of the workpiece, and improves the high quality. surface processing efficiency. [0003] The wiper blades disclosed in the patents "A Wiper Blade ...

AI Technical Summary

Problems solved by technology

Due to the large extrusion wiper force and high cutting temperature of the linear wiper edge, the service life of the tool is limited, and at the same time, built-up edge is easy to occur during processing, which affects the quality of the processed surface
