Fluidics leads extrahigh voltage water aviation production development

1~0.

The eject of man-made sapphirine nozzle of 5mm and the high speed efflux that produces 800~1000m/s, apply arrow of water of this bundle of high speed or rejoin a few fine arenaceous make pressing shoot and move and form cut to workpiece, the temperature that its produce is highest in 60 ℃ less than, friend can say for " technology of cold conditions cut " . This technology applicability is extensive, can process very very thin, soft metal and metalloid data, for example 779 kinds of material such as copper, aluminous, plastic, lumber, balata and goods, can replace cutting tool of hard alloy grooving. And can according to aleatoric angle cut, have be out of shape without heat, cut seam narrow, precision tall, tangent plane is bright and clean reach the good point such as green environmental protection. In the form cutting that reachs composite material in structure of alloy of carbon fiber, titanium, aluminium alloy, beehive, water cut technology has become the optimal with accepted international to machine means. 2, the development tendercy of fluidics becomes water on this age bound, the development tendercy that going after high quality, high accuracy, efficient direct form cutting is all sorts of cut and treatment industry, "Water knife " cut machine is aimed at this kind of demand to innovate ceaselessly in technical application domain just about. (1) of high accuracy " water knife " the occurrence that numerical control machine tool reachs a technology to wait as the accurate component of accurate machine tool, the machine tool can achieve speed of taller positional precision, motion and directional clearance compensation, rise repeat fixed position precision. Analyse the account that error of machine tool geometry produces, repass uses the high accuracy such as ball lever measuring instrument and laser interferometer to measure appliance to detect precision of machine tool geometry, build error map watch to give precision to amend, make high accuracy machine tool with this. (2) technology of 5 axle control realizes rake or perpendicular cut comes out at was being carried 1997 tilt the tentative idea of cut head, there already was business to be supplied with the product on international at present. This is to solve cut rake, raise the method with treatment the directest and effective precision. Its characteristic is to be in original two runner shaft coming back increase again on the foundation of X of 3 axes platform, Y, Z, make knife head swings to any direction, use the rake model that sets beforehand in the system, through reaching computation to the modal analysis of cut contrail, the data that considers pair of work that be cut again and ply undertake correction, swing ceaselessly in cut process cut head, make the workpiece that cut comes out achieves perfect rake or perpendicular (or angle) cut. (3) 6 axes robot " water knife " -- system of cut of dimensional curve water " robot water knife " apply precision of agile, convenient, cut tall. System of cut of its cent pure water and add arenaceous cut system two kinds big, can curve of cut random space. Current, technology already hasten is mature, apply extensively already at car interior trim the cut that reachs dimensional curve component part. (4) energy of efflux of water of system of high-power superhigh pressure is bigger, cut effect is better, so the pressure of water cut machine and output discharge become the main parameter that affects cut ability. Study a proof according to abroad: When pressure achieves 700MPa above, also can use thin stencil steel of pure water cut and better composite material (pressure crosses small conference to reduce cut edge quality, be opposite especially composite material, cause material easily to leave a layer or have like the scales of a fish) . But raise systematic pressure to be able to bring a lot of difficult problem, under photograph comparing, the flow that increases a system will be a few easier. Additional, it is under coequal pressure, the power that increases efflux can increase cut capacity likewise, produced technology of much supercharger paralell connection for this, can relatively the output flow that increases supercharger conveniently, use large requirements nozzle to have cut, water efflux is effective cut energy is bigger, the effect is better. Develop and use afore-mentioned new technologies and new facility to be able to finish a spare parts to detect, a variety of cut such as oriented, long edge and bore machine demand, can leave out purchases multinomial equipment, save a product to go up in a variety of equipment be on the move flow, realize fixed position treatment, raised the treatment precision of the product and manufacturing cost. 3, fluidics is in water the rapid development that the application in aviation industry is start with energy-saving environmental protection as aviation industry, use new material, new technology, new structure extensively, bring from this explore production new method. Aviation manufacturing industry is " water knife " domain of a key application. (1) the crust plane crust of the plane uses alloy of steel, stainless steel, titanium, aluminium alloy and carbon fiber material to be made more, be aimed at this kind of material to be able to use large cut machine character, head of cut of system of 400MPa high-power high pressure, 5 axle control undertakes cut is machined. (2) the framework structural member such as airframe, wing, landing gear these components not only have high strength demand, and below the condition that asks in contented intensity, need to reduce oneself weight again, reduce specific power consumption, for this commonly used material has alloy of alloy steel, stainless steel, aluminium alloy, titanium and carbon fiber to wait. Right from Boeing the 777 rears with airbus A380 are mixed to Boeing 7E7 the wing of F117; Surprise to A handkerchief from the turbine lamina of the reaction engine helicopter, can use in the light of these structural member muti_function machine of water knife cut, system of 400MPa high-power high pressure, head of 5 axes cut undertakes cut is machined. (3) the conduit of ventilated system and connection flange consider ventilated system to often use titanium, aluminium alloy and carbon fiber to be made, be aimed at this kind of material to be able to use system of high pressure of the small-power in 400MPa character, medium or small cut machine and general cut head undertake cut is machined. (4) these components such as interior trim, seat use aluminium alloy, project more plastic bracket bearings. Use expanded plastics to be gasket, it is wrapping with chemical fibber cloth, leather, leatheroid, can use robot water knife (6 axle control) , system of high pressure of the small-power in 400MPa, head of pure water cut undertakes cut is machined. (5) plane door window and inside lie between screen to wait for them to use glass and clip glue glass to be made. Can use medium or small system of high pressure of small-power of cut machine, 300~400MPa, head of general water cut or water cut machining center undertake cut is machined. 4, epilogue abroad is used successfully when adding arenaceous water knife to have bore and cut to composite material, need not undertake the surface comes off, can mix easily new-style existing perhaps robot and mast are compositive together, can feel short-term run fast and new process designing, change quickly or cancel nose, pattern plate, guider and handiwork to decorate a border. Can make the rate of cut composite material rapidder so, tool life is longer, do not produce dust, can cleaner, more improve manufacturing efficiency surely. CNC Milling CNC Machining
