Description
Technical field
The utility model application relates to a kind of near dry cutting supersonic velocity device, be mainly used in the cooling of high-speed numeric control metal and nonmetal stock-removing machine cutter, and general NC metal and nonmetal stock-removing machine and common metal and nonmetal stock-removing machine cutter is cooling.
Background technology
Near dry cutting is relative DRY CUTTING and wet type cutting; on the cutting edge of cutting tool, spray one deck lubricating oil; in the time of machining; rely on the relative viscosity of lubricating oil; make lubricating oil between cutter and workpiece, form one deck oil film; reduce heat generation, protection cutter and workpiece, improve Workpiece Machining Accuracy.Especially more obvious in the Precision Machining of cutting in a small amount.In working angles, need to carry out cutter and workpiece coolingly, spray and coolingly exactly micro liquid is sneaked in forced draft, form vaporific gas-liquid two-phase fluid, by spraying, produce jet, be ejected into cutting region, make workpiece and cutter obtain abundant Cooling and Lubricator.
At present near dry cutting injection apparatus on the market, exists not for lubricating fluid suction, and injecting time and signal lag are excessive.And the disadvantage such as nozzle dropping liquid.
Utility model content
The utility model is the problems referred to above that exist for current near dry cutting injection apparatus, especially sprays the problem of time delay, and a kind of new near dry cutting supersonic velocity device is provided.
Specifically, near dry cutting described in the utility model supersonic velocity device, comprise control circuit board, supersonic jet injector, nozzle, cutting fluid carrier pipe, blowpipe and regulating block, supersonic jet injector is arranged on nozzle, regulating block comprises Pneumatic cutting liquid unidirectional stop valve, cutting fluid control valve and compressed air regulating valve, cutting fluid carrier pipe connects cutting fluid storage tank and supersonic jet injector, on cutting fluid carrier pipe, from cutting fluid storage tank to supersonic jet injector, be provided with successively Pneumatic cutting liquid unidirectional stop valve and cutting fluid control valve, blowpipe connects compressed air source and supersonic jet injector, on blowpipe, from compressed air source to supersonic jet injector, be provided with successively and control magnetic valve and compressed air regulating valve, described control magnetic valve connects Pneumatic cutting liquid unidirectional stop valve by tube connector.
Further, described control magnetic valve is two-position-five-way solenoid valve.
So-called two-position-five-way solenoid valve is the automation foundation element for controlling fluid, belongs to actuator; Be not limited to hydraulic pressure, pneumatic.Magnetic valve is used for controlling hydraulic flow direction, and the mechanical device of factory is generally all by hydraulic cylinder control, so will use magnetic valve.In magnetic valve, there is airtight chamber, diverse location have through hole, different oil pipes is led in each hole, in the middle of chamber, it is valve, two sides is two blocks of electromagnet, which side the magnet coil energising valve body of which face will attracted to, by the movement of application valve body, carry out shelves and live or spill different holes, and inlet hole is often opened, liquid will enter different pipes, then by the pressure of liquid, promotes piston, and piston drives again piston rod, the motion of piston rod driving mechanical device, has just controlled mechanical movement by the electric current of controlling electromagnet like this.
Further, described cutting fluid unidirectional stop valve is pneumatic control valve.
Further, the suction of described cutting fluid supersonic injectors is 0.3 to 0.9 atmospheric pressure.
When lathe sends injection signal, control magnetic valve is opened, compressed air promotes Pneumatic cutting liquid unidirectional stop valve, cutting fluid carrier pipe is opened, by the supersonic jet injector of nozzle, start to spray simultaneously, the vacuum that supersonic jet injector causes sucks supersonic jet injector by cutting fluid mixes with compressed air, together ejection; When injection signal cut-off, control closed electromagnetic valve, compressed air pushes back closed condition by the spool of Pneumatic cutting liquid unidirectional stop valve, lubricant channel is closed, due to the effect of Pneumatic cutting liquid unidirectional stop valve, whole cutting fluid pipeline is full of cutting fluid, and no liquid refluxes, also just solved the cutting fluid latency issue when suction comes up again again, cutting fluid control valve and compressed air regulating valve play the function that regulates respectively cutting fluid and compression control uninterrupted.
Near dry cutting described in the utility model application supersonic velocity device, owing to having adopted supersonic jet injector, therefore the cutting fluid of this injector can be placed on any position of lathe, also, owing to having adopted cutting fluid Pneumatic unidirectional stop valve, well solved the problem of spraying time delay and nozzle dropping liquid.And the compressed-air actuated temperature penetrating can reduce 6-10 ℃ than normal temperature.
