Description
Technical field
The invention belongs to special processing technology device, it is related to a kind of precise fine abrasive water jet system.
Background technology
Abrasive waterjet cutting is generated from the new special beam process technology of 1980s, due to its tool
Have the advantages that elaboration power is small, small to material heat affecting, machinable material scope is wide, be developed rapidly over nearly 30 years,
Application in Practical Project is increasingly extensive.In recent years, due to processing increasingly precise treatment, abrasive material increasingly miniaturization, abrasive material
The fine precisions such as water jet machining technology is polished via roughing such as initial cuttings to surface, micro etch, capillary processing add
Work direction is developed.
Different according to abrasive material hybrid mode, abrasive water-jet can be divided into preceding mixing and rear mixing two ways.Preceding mixing side
Formula is that abrasive material is first and water is tentatively mixed into abrasive material slurry, and then abrasive material slurry is uniformly mixed into hybrid chamber with high-speed water jet,
Accelerate to spray by nozzle again.Preceding hybrid mode abrasive particle energy transmission efficiency is high, is adapted to cutting steel and steel at low pressures
The materials such as reinforced concrete, the problem of existing is the drastically abrasion for easily causing fluid conduit and nozzle.Hybrid mode is to pass through afterwards
Pressure charging system is initially formed water jet, and high-speed water jet forms certain vacuum in hybrid chamber, and abrasive material is in deadweight and pressure
Hybrid chamber is entered by pneumatic transportation under the collective effect of difference, and occurs violent turbulent fluctuation diffusion and blending with water jet.After mix
Mode weares and teares smaller to jet nozzle, but abrasive material can not be sufficiently mixed with high-speed water jet, and water is transmitted to the energy of abrasive material
Efficiency is low.
Especially, in precise fine abrasive water jet processing, pressure charging system pressure is relatively low, and output is smaller, fine to penetrate
Stream is more difficult to form stable negative pressuren zone in mixing tube, and abrasive material is mixed with high-speed water jet becomes more difficult.Moreover, accurate micro-
Abrasive size used in finer abrasive water jet is smaller, and abrasive material has easy arch camber, the phenomenon reunited.It is limited by original processing side
, no doubt there is abrasive material and difficulty, the problem of concentration is uncontrollable mixed with high-speed water jet in formula.These problems limit precise fine
The development of Abrasive Waterjet Machining Technology.
The content of the invention
In order to which the abrasive concentration for overcoming the shortcomings of existing abrasive waterjet cutting mode is uncontrollable, processing efficiency is relatively low,
The invention provides a kind of abrasive concentration it is controllable, it is effective lifting processing efficiency precise fine abrasive water jet system.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of controllable precise fine abrasive water jet system of abrasive concentration, including fluid pump, pressure regulator valve, pressure vessel,
Air bag and nozzle, the fluid pump are provided with flow inlet, and the high-pressure outlet of the fluid pump is held by pressure regulator valve and the pressure
The import connection of device, the air bag is the air bag for placing the abrasive material slurry mixed by setting ratio, and the air bag goes out
Material mouth connects with discharge nozzle one end of the pressure vessel, and the other end of the discharge nozzle sets the nozzle, the nozzle position
Above the processing stations of work piece holder.
Further, preposition electronic switch valve is provided with the import of the pressure vessel, the discharge nozzle is provided with rearmounted electricity
Sub switch valve.
In the present invention, fluid pump extracts water from water tank, makes water occur to be pressurized and be transported in pipeline and pressure vessel.Pipe
Road is provided with pressure regulator valve and electronic switch valve.Pressure regulator valve is used for adjusting the pressure of pipeline mesohigh water.Electronic switch valve is used for opening
Open and end the water under high pressure for being transported to pressure vessel.There is an air bag inside pressure vessel, air bag has high leakproofness, wearability
And elastic deformability.Be stored with mixed uniformly abrasive material slurry in air bag.Therefore, gasbag isolation water under high pressure and abrasive material slurry.It is high
Pressure water is entered after pressure vessel, can only extruding gasbag due to being stopped by container wall.Rearmounted electronic switch valve is opened,
Abrasive material slurry in air bag is spouting at nozzle, realizes the abrasive waterjet cutting of workpiece.This water jet system it is excellent
Point is to be put into certain density abrasive material after air bag, and concentration will not change with the progress of processing, and due to subtracting
Small abrasive material slurry volume is replaced by water under high pressure, and the tonnage of abrasive water-jet keeps stable.
Beneficial effects of the present invention are mainly manifested in：Abrasive concentration is controllable, effectively lift processing efficiency.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Reference picture 1, a kind of controllable precise fine abrasive water jet system of abrasive concentration, including fluid pump 2, pressure regulator valve 3,
Preposition electronic switch valve 4, pressure vessel 5, air bag 7, electronic switch valve 8 and nozzle 9, pure water 1 and abrasive material slurry 6 are in figure with not
Represented with hatching.Because pure water and abrasive material slurry are by the isolation of air bag 7, both do not mix.
The water inlet of fluid pump 2 is connected by pipeline with the pure water 1 in water tank.The delivery port of fluid pump 2 passes through pressure regulator valve
3rd, electronic switch valve 4 is connected with pressure vessel 5.Fluid pump 2 extracts water from water tank, make water occur be pressurized and be transported to pipeline and
In pressure vessel 5.Pipeline is provided with pressure regulator valve 3 and preposition electronic switch valve 4.Pressure regulator valve 3 is used for adjusting pipeline mesohigh water
Pressure.Electronic switch valve 8 is used for opening and ending the water under high pressure for being transported to pressure vessel.
There is an air bag 7 inside pressure vessel 5, air bag 7 has high leakproofness, wearability and elastic deformability.In air bag 7
Be stored with mixed uniformly abrasive material slurry 6.Air bag 7 isolates water under high pressure 1 and abrasive material slurry 6.Water under high pressure 1 enters pressure vessel 5
Afterwards, can only extruding gasbag 7 due to being stopped by container wall.Open the abrasive material slurry in rearmounted electronic switch valve 8, air bag 7
6 is spouting at nozzle 9, realizes the abrasive waterjet cutting of workpiece.
During processing, start fluid pump 2, open preposition electronic switch valve 4, water under high pressure 1 is continuously transported to high pressure
Container 5, is gradually filled with high-pressure bottle 5, and air bag 7 and abrasive material slurry 6 start to be squeezed.Now, due to electronic switch valve 8 not yet
Open, so abrasive material slurry 6 will not be ejected.Adjust pressure regulator valve 3, it is ensured that the hydraulic pressure of container 5 meets processing request.Open rearmounted
Electronic switch valve 8, abrasive material slurry 6 is spouting at nozzle 9.As abrasive material slurry 6 is gradually decreased, the volume of air bag 7 is gradually
Diminish, the water under high pressure 1 that the volume of reduction is constantly poured in replaces, so the pressure that air bag 7 and abrasive material slurry 6 are squeezed
It is constant, so as to ensure that the stability of processing.The advantage of this water jet system is put into certain density abrasive material
To after air bag, concentration will not change with the progress of processing.
