Ultrasonic cutting principle

超声波切割机的原理与传统意义上的切割完全不同。超声波切割原理是通过超声波发生器将50/60Hz电流转换成20、30或40KHz电能。被转换成为同等频率的机械振动，随后机械振动通过一套可以改变振幅的调幅器装置传递到切割刀。切割刀将接收到的振动能量传递到待切割工件的切割面，在该区域，振动能量被通过激活橡胶分子能，打开分子链的方式对胶料进行切割。这对粘性和弹性材料、冰冻材料，如食品，橡胶等，或不便加压力的物体切割，特别有效。超声波切割还有一个很大的优点，就是它在切割的同时，在切割部位有熔合作用。切割部位被完美地封边了，可防止被切割材料组织的松散（如纺织材料飞边）。超声波切割机的用途还可以扩展，如挖孔，铲挖，刮漆，雕刻，分条等等。

Ultrasonic cutting completely different cutting machine principle and the traditional sense of the. Ultrasonic cutting principle is by the ultrasonic generator to convert the 50/60Hz current of 20, 30 or 40KHz power. Be converted into mechanical vibration of equal frequency, then the mechanical vibration through a set of can change the amplitude modulation device is transferred to the cutting knife. Cutting vibration energy is received to transfer to the cutting surface of the workpiece to be cut, in this region, the vibration energy is activated through the rubber molecules can open the molecular chain, the way of cutting material of rubber. This pair of viscous and elastic material, frozen material, such as food, rubber, or inconvenience plus pressure cutting objects, particularly effective. Ultrasonic cutting has a lot of advantages, it is in the cutting at the same time, a fusion effect in cutting parts. Cutting edge position is perfect, can prevent the material to be cut loose organization (such as textile material flash). The use of ultrasonic cutting machine can be extended, such as digging, digging, scraping paint, sculpture, strip and so on.

二、超声波切割基本结构和特点

Two, the basic structure and characteristics of ultrasonic cutting

超声波切割机是利用波能量进行切割加工的一类设备，它最大的特点是切割不用刃口。或者说，不用传统意义上的刃口。传统的切割是利用带有锋利刃口的刀具，压向被切割材料。此压力集中在刃口处，压强就非常大，超过了被切割材料的剪切强度，材料的分子结合被拉开，就被割断了。由于材料是被强大的压强硬性拉开的，所以切割刀具刃口就应该非常锋利，材料本身还要承受比较大的压力。对软性、有弹性的材料切割效果不好，对粘性材料困难更大。

Ultrasonic cutting machine is a kind of equipment for cutting processing and utilization of wave energy, its biggest characteristic is not cutting edge. Or, instead of the traditional sense of the cutting edge. The traditional cutting is to use the tool with sharp edge, pressure to the material being cut. The stress is concentrated at the edge, the pressure is very big, exceeds the shear strength of the material being cut, material molecular binding is opened, it was cut. Because the material is strong pressure of rigid open, so the cutting tool edge should be very sharp, the material itself but also bear more pressure. Not good for cutting elastic material is soft, effect, more difficult for viscous materials.
