An ultrasonic cutting tool

Abstract

The invention discloses an ultrasonic cutting tool. The ultrasonic cutting tool comprises a transducer, a variable amplitude rod, a changeover mechanism and a blade, wherein the transducer is connected with the variable amplitude rod; the top of the changeover mechanism is connected with the variable amplitude rod; and the bottom of the changeover mechanism is connected with the blade. According to the ultrasonic cutting tool, the blade and the changeover mechanism resonate in the same vibration mode under the same frequency, the blade well vibrates, vibration amplitude is uniform, obvious pitch surfaces do not exist on the blade, and the phenomenon of local tool sticking is avoided; besides, the blade is of a flakelike structure, an edge is relatively long, cutting depth is relatively large, processing range is relatively wide, and difference of cut angles of the two ends of a cutting surface and interference between the upper end of the cutting tool and a material are avoided; and the changeover mechanism can be manufactured through an aluminium alloy, cost is reduced, the flakelike blade can be manufactured through stainless steel or alloy steel, hardness is much higher than that of a titanium alloy, the cutting tool can be utilized to cut relatively hard materials, and utilization range of the ultrasonic cutting tool is greatly increased.

Description

technical field [0001] The invention relates to the field of cutting devices, in particular to an ultrasonic cutting tool. Background technique [0002] Viscous materials such as rubber, solid chemical products, printed circuit boards, etc. tend to stick to the knife when cutting, and elastic materials such as frozen meat, candy, chocolate, fruit, cake, etc. are prone to deformation and crush the surface of the material when cutting. Ultrasonic cutting tools use ultrasonic energy to heat and melt parts of the material to be cut to achieve the purpose of cutting. Ultrasonic cutting does not require a sharp edge or a lot of pressure to easily cut the material without causing damage to the material being cut. Chipping, breakage and slag. At the same time, since the blade surface is vibrating ultrasonically, the friction resistance is extremely small, and the material to be cut is not easy to stick to the blade, which can solve the above-mentioned sticking problem. And at the ...
