Abstract
The utility model discloses a metal band saw ultrasonic saw-cutting device. Existing metal band saw machining has the defects that the saw-cutting range is narrow, efficiency is low, and scraps are prone to adhering to saw teeth. The metal band saw ultrasonic saw-cutting 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 eddy current sensor and a sawing machine body. The metal band saw ultrasonic saw-cutting device is good in compatibility with a machine tool, capable of adapting to workpieces with various specifications, low in cost and remarkable in effect. The output frequency of the generator can change along with the change of a load in a tracking mode, so it is guaranteed that the amplitude is always the maximum. Added ultrasonic vibration enables the workpiece to generate vibration in the direction parallel to the saw-cutting direction, so that the saw-cutting length of the saw teeth is increased, and saw-cutting efficiency and the surface quality of the saw-cut workpiece are greatly improved.
