Supersonic vibration assisted fluidifying fine grinding material feeding device

Abstract

The invention relates to a special processing technology, and discloses a supersonic vibration assisted fluidifying fine grinding material feeding device which is particularly applied in a grinding material water jet processing system. The supersonic vibration assisted fluidifying fine grinding material feeding device is composed of an air source, a pressure regulating valve, a frequency converting control circuit, a high-frequency switch valve, an ultrasonic generator and a vibration material bin, wherein the vibration material bin is provided with a material bin air inlet and a material bin air outlet; the air source is connected with the pressure regulating valve through an air delivering pipe, an outlet of the pressure regulating valve is connected with the high-frequency switch valve through the air delivering pipe, and the frequency converting control circuit is connected with a circuit of the high-frequency switch valve; an air outlet of the high-frequency switch valve is connected with an air inlet of the vibration material bin, the vibration material bin is connected with the ultrasonic generator, and a discharging hole of the vibration material bin is connected with a grinding material water jet cutting head mixing cavity. The supersonic vibration assisted fluidifying fine grinding material feeding device provided by the invention has the advantages that the defects that the material supplying capacity of the existing grinding material feeding device is not uniform and the grinding material feeding device is easy to plug are overcome, meanwhile, the precision regulation of the grinding material flow is also realized, and thus the processing quality of the fine grinding material water jet processing technic is greatly improved, and the supersonic vibration assisted fluidifying fine grinding material feeding device has an important popularization and application value.

Description

1. Technical field [0001] The invention relates to a special processing technology, in particular to an ultrasonic vibration-assisted fluidized fine abrasive supply device applied to an abrasive water jet processing system. 2. Background technology [0002] Abrasive water jet processing is a relatively late processing technology. It has the advantages of small force, no thermal effect, clean and so on. Its superior technical characteristics determine that its range of processing materials is very large, especially suitable for processing various heat-sensitive, pressure-sensitive, brittle, multi-layer, composite, superhard materials, such as hard alloy, metal, silicate glass, ceramics , marble, fiber composite materials, etc. According to the different mixing methods of water and abrasive, the technology can be divided into pre-mixed abrasive water jet and post-mixed abrasive water jet. In the pre-mixing mode, the abrasive is uniformly mixed with water to form an abrasive...
