Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] refer to figure 1 , a precision micro-abrasive water jet system with controllable abrasive concentration, including a fluid pump 2, a pressure regulating valve 3, a front electronic switch valve 4, a pressure vessel 5, an air bag 7, an electronic switch valve 8 and a nozzle 9, pure water 1 and abrasive slurry 6 are shown with different hatching in the figure. Since the pure water and the abrasive slurry are separated by the air bag 7, the two are not mixed.

[0015] The water inlet of the fluid pump 2 is connected with the pure water 1 in the water tank through a pipeline. The water outlet of the fluid pump 2 is connected with the pressure vessel 5 through the pressure regulating valve 3 and the electronic switch valve 4 . The fluid pump 2 draws water from the water tank, pressurizes the water and delivers it to the pipeline and the pressure vessel 5 . The p...

Abstract

A precise micro abrasive water-jet system with the controllable abrasive concentration comprises a fluid pump, a pressure regulating valve, a pressure container, an air bag and a nozzle; a water flow inlet is formed in the fluid pump; a high-pressure outlet of the fluid pump is connected with an inlet of the pressure container through the pressure regulating valve; the air bag is used for accommodating abrasive slurry mixed in the set proportion; a discharging port of the air bag is connected with one end of a discharging pipe of the pressure container; and the nozzle is arranged at the other end of the discharging pipe and is located above the machining station of a workpiece fixture. With the precise micro abrasive water-jet system, the abrasive concentration is controllable, and the machining efficiency is effectively improved.

Description

technical field [0001] The invention belongs to a special processing technology device and relates to a precision fine abrasive water jet system. Background technique [0002] Abrasive water jet processing is a new type of special energy beam processing technology produced in the 1980s. Due to its advantages of small processing force, small thermal impact on materials, and a wide range of machinable materials, it has developed rapidly in the past 30 years. , is increasingly widely used in practical engineering. In recent years, due to more and more precise processing and finer abrasives, abrasive water jet processing technology has developed from rough processing such as cutting to surface polishing, micro-etching, micro-hole processing and other micro-precision processing. [0003] According to different abrasive mixing methods, abrasive water jet can be divided into two methods: pre-mixing and post-mixing. The pre-mixing method is that the abrasive is initially mixed wit...
