Ultrasonic cutting device

Abstract

The invention discloses an ultrasonic cutting device, and relates to the technical field of ultrasonic cutting. The ultrasonic cutting device comprises a knife handle and a cutting knife arranged at the bottom of the knife handle, an amplitude modulator is arranged in the knife handle, a fixing plate is arranged at the top of the knife handle, a plurality of heat dissipation holes are formed in the side wall of the fixing plate, and a plurality of supporting rods arranged in an array mode are fixedly connected to the top of the knife handle. The amplitude modulator in the knife handle can be cooled, the cooling speed of the amplitude modulator can be automatically adjusted according to the feeding speed of the cutting knife, damage to the amplitude modulator is avoided, meanwhile, the surface of a cut material can be cooled, cooling is not conducted in the cutting direction, solidification of a molten material is accelerated, diffusion of the molten material is avoided, the cutting quality and efficiency are guaranteed, during use, heat dissipation of the surface of the cut material can be guaranteed regardless of the direction of the knife handle and the feeding direction of the cutting knife, heat dissipation in the cutting direction is avoided, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of ultrasonic cutting, in particular to an ultrasonic cutting device. Background technique [0002] Ultrasonic cutters use high-frequency vibrating blades to cut materials. Some hard resins, plastics, circuit boards, and 3D printed objects can be easily cut, and can also be polished with a sanding stick. [0003] Its working principle is to convert 50 / 60Hz current into 20, 30 or 40kHz electric energy through an ultrasonic generator, and the converted high-frequency electric energy is converted into mechanical vibration of the same frequency again through the transducer, and then the mechanical vibration can be changed by a set of The amplitude modulator device of the amplitude is transmitted to the cutting knife, and the cutting knife transmits the received vibration energy to the cutting surface of the workpiece to be cut. In this area, the vibration energy is activated by activating the rubber molecular e...

Problems solved by technology

[0004] However, when cutting plastic, resin and other materials, due to the high temperature generated during cutting, the material after cutting will melt. If the heat dissipation and cooling treatment is not carried out in time, the molten material will spread, thereby affecting the quality of cutting. Moreover, When the cutting speed is fast, the transducer will generate high heat, if it is not cooled down in time, it will be damaged
