The invention discloses a metal band saw ultrasound saw cutting machining method and device. In current metal band saw machining, the shortcomings that the saw cutting range is narrow, efficiency is low, and filings can adhere to saw teeth easily exist. The device comprises an ultrasonic generator, an ultrasonic transducer, an ultrasonic amplitude transformer, an ultrasonic mechanism support, an ultrasonic tool rod, a workpiece, a sawing machine base, an electric vortex sensor and a sawing machine body. The compatibility with a sawing machine is good, the method and device can be adaptive to workpieces with various specifications, cost is low, and effect is obvious. The output frequency of the generator can carry out tracking changing along with load changing, and the fact that amplitude is largest all the time is guaranteed. Ultrasonic vibration is added, so that the workpiece generates vibration parallel to the saw cutting direction, the saw cutting length of the saw teeth is enlarged, and saw cutting efficiency and the surface quality of the saw cutting workpiece are greatly improved.
Description
Technical field: [0001] The invention relates to an ultrasonic-assisted band saw processing device, in particular to a metal band saw ultrasonic sawing processing method and device. technical background: [0002] Metal band sawing machine is the equipment required for the first process of machining and manufacturing. Its processing accuracy and degree of automation are directly related to the efficiency and quality of subsequent processes. However, due to the technical limitations of traditional processing methods, when sawing high-hardness materials The cutting efficiency will be greatly reduced, and the wear of the metal band saw blade will be accelerated, the sawing load of the motor will be increased, and the roughness of the processed surface will also be increased. [0003] Ultrasonic machining technology is one of the most suitable technologies for processing hard and brittle materials. It removes the processed material on the workpiece by means of ultrasonic vibratio...
