Abstract
The invention discloses a gas-liquid mixing nozzle based on compressed air. The gas-liquid mixing nozzle comprises a compressed air joint, a jet nozzle, a liquid inlet joint and a guide nozzle, wherein the compressed air joint, the jet nozzle and the guide nozzle are connected in sequence; the axial leads of inner holes of the compressed air joint, the jet nozzle and the guide nozzle are positioned on the same straight line; and the liquid inlet joint is connected with the guide nozzle. The jet nozzle is designed according to a Venturi principle, the internal section is reduced gradually, the flow speed of air flowing through the jet nozzle is increased, a ''vacuum'' region is formed on the back side of a jet nozzle outlet, and liquid in the liquid inlet joint is adsorbed and driven to move forward together for cooling and cleaning workpieces, so that working reliability is realized, and good cooling and cleaning effects are achieved; the gas-liquid mixing nozzle is simple in structure, and is convenient to install, use and maintain; and components such as the compressed air joint, the liquid inlet joint, a sealing ring and the like are commercially available standard parts, so that the components are easy to purchase, and the production cost is low.
Description
Technical field
The invention belongs to the machine cut processing technique field, be specifically related to be used in a kind of stock-removing machine process the gas-liquid mixed nozzle of removing scrap, be particularly suitable for the removing of scrap in the pocket machining process lumen.
Background technology
Die cavity is the groundwork part of mould, it is the critical component of molded article, be mainly used to the contoured surface of molded article, its precision and surface quality are had relatively high expectations, the processing of die cavity belongs to the processing of blind hole type inner surface, often has scrap in the process and piles up, if the untimely cleaning of these leftovers, touch the die cavity inner surface, can reduce die cavity precision and inner surface quality; In addition, in the relative high speed rotating with die cavity of cutter, the accumulation of scrap also can damage cutter, causes the cutter operational failure, and has potential safety hazard.
A lot of machine cut processing industries is arranged at present, clean when adopting cutting fluid that workpiece is cooled off, but cutting fluid is used for pocket machining, add man-hour along with the increase of working depth so that cutting fluid is assembled in die cavity, can't reach the cleaning purpose; Also some enterprise adopts compressed air directly to blow down smear metal in the chamber in actual process, and this kind method can effectively be got rid of smear metal in the chamber, but owing to do not have cutting fluid so that the non-constant of cooling effect, cutter life is greatly affected; Also some enterprise uses high-pressure pump to carry out the cutting fluid supply in addition, and this kind method also can effectively solve the problem of smear metal, but cost compare is high, needs the good filtration system of a cover, and maintenance cost is high; Also have in addition Some Enterprises to adopt mist of oil combination cooling device, this kind method not only apparatus cost is high and produce easily a large amount of mist of oils when using, and pollutes workshop condition.
Summary of the invention
The above-mentioned technical problem that exists in the prior art field in order to overcome pocket machining the object of the invention is to, and provides a kind of based on compressed-air actuated gas-liquid mixed nozzle, simple in structure, good cooling results, and scrap is removed clean.
Provided by the invention based on compressed-air actuated gas-liquid mixed nozzle, comprise compressed air joint, jet nozzle, liquid inlet joint and directional nozzle, described compressed air joint, jet nozzle and directional nozzle connect successively, the axial line of three's endoporus is located along the same line, and described liquid inlet joint is connected with directional nozzle.Described compressed air joint is connected with the workshop compressed air line, and compressed air mixes at directional nozzle with the liquid that injects from the liquid inlet joint through jet nozzle.Also be provided with sealing ring between described jet nozzle and the directional nozzle, the cross section of described jet nozzle inside diminishes step by step, and described directional nozzle diameter of bore is greater than the diameter of bore of the minimum spout of jet nozzle front end.
Provided by the invention based on compressed-air actuated gas-liquid mixed nozzle, its beneficial effect is, adopt venturi principle, the cross section of jet nozzle inside diminishes step by step, makes through the air velocity of jet nozzle very fast, and form one " vacuum " district at the rear side of jet nozzle outlet, this region of no pressure can produce suction-operated to the liquid in the joint of liquid inlet, drives liquid and flows forward together, and workpiece is cooled off cleaning, reliable operation has good cooling and cleaning performance; Simple in structure, installation and easy to use is convenient to safeguard; Compressed air joint, liquid inlet joint and seals and other component all adopt commercially available standard component, buy easily, and production cost is low.
Description of drawings
Fig. 1 is the overall structure schematic diagram of one embodiment of the invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 2.
Mark among the figure:
1. compressed air joint; 2. jet nozzle; 3. liquid inlet joint; 4. directional nozzle; 5. sealing ring.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, be described in detail based on compressed-air actuated gas-liquid mixed nozzle provided by the invention.
Embodiment
With reference to Fig. 1-Fig. 3, present embodiment based on compressed-air actuated gas-liquid mixed nozzle, comprise compressed air joint 1, jet nozzle 2, liquid inlet joint 3 and directional nozzle 4, described compressed air joint 1, jet nozzle 2 and directional nozzle 4 connect successively, the axial line of three's endoporus is located along the same line, and described liquid inlet joint 3 is connected with directional nozzle 4.Described compressed air joint 1 is connected with the workshop compressed air line, and compressed air mixes at directional nozzle 4 with the liquid that injects from liquid inlet joint 3 through jet nozzle 2.Also be provided with sealing ring 5 between described jet nozzle 2 and the directional nozzle 4, the cross section of described jet nozzle 2 inside diminishes step by step, and described directional nozzle 4 diameter of bores are greater than the diameter of bore of the minimum spout of jet nozzle 2 front ends.
Based on compressed-air actuated gas-liquid mixed nozzle, operation principle is as follows: compressed air joint is connected with the workshop compressed air line, compressed air enters jet nozzle by compressed air joint, the cross section that process jet nozzle inside diminishes step by step, make the compressed air flow velocity very fast, finally the spout from jet nozzle front end minimum sprays at a high speed, its rear of the gas of ejection produces negative pressure at a high speed, rear side in the jet nozzle outlet forms one " vacuum " district, liquid in the joint of liquid inlet is produced suction-operated, drive liquid and spray into together directional nozzle, liquid is at a high speed ejection after the endoporus of directional nozzle mixes with Compressed Gas under the drive of high-speed gas, and workpiece is cooled off cleaning.
At present, the employed compressed air pressure of domestic factory at 0.4Mpa between the 0.8Mpa, all be not less than 0.4Mpa, therefore enter the compressed air of compressed air joint, as long as by the pressure adjustment, just can obtain different outlet pressures, the fluid flow that enters the liquid inlet joint by adjustment changes the gas-liquid ratio, thereby obtains good cooling and cleaning performance by compressed-air actuated powerful impact.
Based on compressed-air actuated gas-liquid mixed nozzle, compare with traditional cold high pressure radiator cooler, do not need high-pressure oil pump and filter, the mist of oil synthesizer that does not also need mist of oil combination cooling device, liquid can be pumped into directional nozzle by absorption or the small-power pump of high velocity air, simple in structure, be convenient to safeguard.
Based on compressed-air actuated gas-liquid mixed nozzle, employed compressed air joint, liquid inlet joint and seals and other component all adopt commercially available standard component, just can use by the combination fixed installation, and easy to manufacture, cost is low.
