Abstract
The present invention relates to equipment for cutting material with high jet flow water beam and capable of cutting workpieces of various soft and hard materials, and belongs to the field of mechanical processing. The novel high pressure water cutting equipment provided by the invention can pressurize the water to a required high pressure (such as 300MPa) through a supercharger, and form extremely high speed water jet through a set nozzle, so as to convert pressure energy into kinetic energy. A technical scheme adopted by the invention is as below: a pressurization system adopts a three-throw ram pump for pressurization, and pressurizes the water to a working pressure of180-250 Mpa; then the water is added with specific abrasive, sent to a 0.8 or 1.0mm diameter nozzle, and jetted out at a speed 2 times of sound, thus completing the material cutting process.
Description
Technical field
The present invention relates to the equipment that a kind of high water jets bundle comes cutting material, the workpiece that can cut off various soft or hard materials belongs to field of machining.
Background technology
The water under high pressure cutting is mainly used in specific alloy material, thick metal material, composite, marble, glass, organic synthesis material, timber, pottery, plastics and various nonmetallic materials or the like.The advantage of water under high pressure cutting method is: do not have machinery, heating is caused or chemical reaction to the influence of workpiece.Material is convenient to handle, and various materials can both cut, and cutting section is excellent; Hard material or very thick material also can process meticulous part.Can any complex outline of cutting.Waste of material is little.
Summary of the invention
The present invention provides a kind of novel water under high pressure cutting equipment, through booster hydraulic pressure is increased to required high pressure (like 300MPa), and passes through the water jet of the nozzle formation flank speed of setting, converts pressure energy into kinetic energy.
The technical scheme that the present invention adopts is: pressure charging system adopts the three-throw ram pump supercharging mode, is forced into water the operating pressure of 180-250Mpa.Add specific abrasive material again and deliver to 0.8 or the 1.0mm diameter nozzle, water is sprayed, thereby accomplish cutting process material with 2 overtone speed.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a device profile of the present invention.Wherein:
1. framework, 2. booster, 3. accumulator, 4. nozzle, 5. clamping device.
The specific embodiment
Water jet or abrasive material aqueous mixtures penetrate from the nozzle of diameter 0.1mm～0.2mm with speed 100m/s under 200～300MPa pressure.Jet sucks abrasive powder by means of the course of injection at nozzle entry from bucket special.The kinetic energy of water jet will be passed to abrasive grain, thereby remove little bits from being cut blank.When cutting power reaches 30kW when above, working head can freely be held with the clamping device of numerical control robot.The microprocessor numerical control device of robot can arbitrarily angled the realization down cut in the space.
The layout of water jet equipment adopts the portal frame layout.When working head moves when having enough QA servo control mechanism along the Z axle, can process pipe, comprising non-round.The workbench of blank location usefulness can be made lattice shape with the pin of anti-corrosion plate, woven wire, sharpening and process; Formation such as the available loose material in workbench surface, settling tank is made by corrosion-resisting steel, and transmission device is configured in the contour dimension of framework; Be provided with the control limit switches at zero point; The servicing area is arranged in length one side of framework, and loading area can be unlimited fully, and framework has very high bearing capacity.
The critical piece of water jet machine is a ultra-high pressure apparatus.Variable pump, one or several boosters, accumulator, hydraulic part, fluid regulating system (filtering and cooling), auxiliary pump, smart water filter and electric appliance control box by hydraulic means case, band drive motor are formed.In double-acting supercharger, fluid prepares to infeed low pressure from 1 pump through switching-over (in the hydraulic cylinder of general 12MPa～16PMa), forces its piston to move with the piston of high pressure liquid cylinder pressure.Because the ratio of the work area of low pressure and high pressure liquid cylinder pressure piston is (20～30): 1, can guarantee the pressure of corresponding raising water.Pressure oscillation when the accumulator of the general about 2.5L of installed capacity on the Pressure Increasing Oil-Line of oil pump, the piston reverses direction of available buffer hydraulic cylinder.
