Detailed description of the invention
In order to make the technical solution of the utility model clearer, below in conjunction with accompanying drawing, water jet machining device of the present utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model and to be not used in restriction the utility model.
Referring to Fig. 1 to Fig. 8, as shown in Figure 1, water jet machining device of the present utility model comprises for pressing system 100, spraying system 200 and feeding system 300, and is connected to respectively spraying system 200 for pressing system 100 and feeding system 300.Wherein, comprise water supply installation 110, pressurized equipment, energy storage device, pressure control mechanism, high-pressure water tank, power source and buffer medium feed mechanism 120 for pressing system 100; Feeding system 300 comprises control valve, feeding abrasive material mechanism 310 and abrasive material storehouse, and control valve and abrasive material storehouse are connected to respectively feeding abrasive material mechanism 310; Spraying system 200 comprises mulling chamber 210, shaping tube 220 and nozzle 230, and shaping tube 220 is arranged between mulling chamber 210 and nozzle 230, be that the outlet in mulling chamber 210 and the first entrance 221 of shaping tube are connected, the outlet 223 of shaping tube is connected with the entrance of nozzle 230.
Water supply installation 110 is connected with pressurized equipment, energy storage device and high-pressure water tank successively, and pressurized equipment is connected with pressure control mechanism respectively with energy storage device.Pressurized equipment forms water under high pressure for low-pressure water that water supply installation is provided, and energy storage device is for the hydraulic pressure of stable high voltage water, and high-pressure water tank is used for storing water under high pressure, and high-pressure water tank is connected with mulling chamber 210, for water under high pressure is injected in mulling chamber 210.
Feeding abrasive material mechanism 310 is connected with mulling chamber 210, for abrasive material being incident upon to mulling chamber 210.Abrasive material forms mixed liquor after carrying out in mulling chamber 210 with water under high pressure mixing fully, then mulling chamber 210 is injected mixed liquor in shaping tube 220 from the outlet low speed in mulling chamber 210 with middle pressure, formation center water jet, wherein, the speed of center water jet is far longer than the speed of mixed liquor.Like this, because the flow velocity of mixed liquor is lower, reduced the friction between abrasive material and mulling chamber 210 inwalls in mixed liquor, thereby reduced the wear rate in mulling chamber 210.
The input of buffer medium feed mechanism 120 is connected with power source, and the output of buffer medium feed mechanism 120 is connected with the second entrance 222 of shaping tube 220, for buffer medium being injected to shaping tube 220.In the present embodiment, buffer medium feed mechanism 120 is injected buffer medium in shaping tube 220 with middle pressure.Buffer medium is wrapped in all sides of center water jet, and the center water jet that is enclosed with buffer medium penetrates and acts on processed workpiece from nozzle 230.
As shown in Figure 6, when the center water jet that is enclosed with buffer medium penetrates from nozzle 230, avoided nozzle 230 to contact with the direct of center water jet that contains abrasive material, thereby reduced the wear rate of nozzle 230.It should be understood that the speed of the center water jet that is enclosed with buffer medium spraying from nozzle 230 is greater than the speed of the center water jet penetrating from mulling chamber 210, can ensure the working ability of this water jet machining device like this.
Preferably, the force value of middle pressure is less than 400 MPas, can save like this energy, reduces the requirement to equipment.Traditional water jet machining adopts pure water water jet machining to replace abrasive waterjet cutting to reduce the wearing and tearing to nozzle 230 and mulling chamber 210, but in order to ensure working ability, requirement more and more higher (more than 400 MPas) to pressure, this has just caused energy loss.In the present embodiment, adopt force value to be less than the middle pressure of 400 MPas, saved the energy.
By buffer medium being wrapped in to all sides of center water jet in shaping tube 220, avoiding direct contact the between abrasive material and nozzle 230 and shaping tube 220, thereby reduced the wear rate of nozzle 230.Mixed liquor low speed is penetrated in mulling chamber 210, because the flow velocity of mixed liquor in mulling chamber 210 is lower, thereby has reduced the wearing and tearing of abrasive material to mulling chamber 210.By using buffer medium and contracted flow effect, effectively control the wearing and tearing of abrasive material to mulling chamber 210 and nozzle 230, make the uniformity of processing obtain accurate control, reduce maintenance cost.
As a kind of embodiment, buffer medium can be liquid, gas or gas-liquid mixture.Preferably, buffer medium can be the mixture of pure water or air or pure water and air.For example, when buffer medium is pure water, pure water is wrapped in all sides of center water jet.Now center water jet is positioned at center, does not directly contact with the inwall of shaping tube 220, and the wearing and tearing of shaping tube 220 depend primarily on the frictional dissipation between pure water and shaping tube 220 inwalls.Avoid like this center water jet that contains abrasive material to contact with the direct of inwall of shaping tube 220, thereby improved the antiwear property of shaping tube 220.Then, nozzle 230 is the center water jet ejection of pure water parcel, and direct contact the between center water jet and the inwall of nozzle 230 of having avoided containing abrasive material reduced the wear rate of nozzle 230.
Certainly, buffer medium can also be other liquid beyond other gases such as air or pure water, or buffer medium is gas-liquid mixture.For example, buffer medium is gas-liquid mixture, and now, liquid is wrapped in all sides of center water jet, and gas wrapping is in all sides of liquid, and gas directly contacts with the inwall of shaping tube 220, has reduced the wear rate of shaping tube 220.
As shown in Figure 8, the center water jet that contains abrasive material does not directly contact with the inwall of nozzle 230, and buffer medium is wrapped in all sides of center water jet, and buffer medium directly contacts with the inwall of nozzle 230.Although the flow velocity of buffer medium in nozzle 230 is greater than the flow velocity of center water jet, but in buffer medium, do not contain abrasive material, so just reduce greatly the wear rate of nozzle 230, extend the service life of nozzle 230, improved the working (machining) efficiency of this water jet machining device and the uniformity of processing.
As a kind of embodiment, the internal diameter of the outlet 223 of shaping tube diminishes gradually along the axial direction of shaping tube 220, due to mass conservation law and contracted flow effect, makes the flow velocity of center water jet become gradually large along the axial direction of shaping tube 220.The axial direction that it should be understood that shaping tube 220 refers to that the first entrance 221 of shaping tube is to the direction of the outlet 223 of shaping tube.Like this, the speed that is enclosed with the center water jet of buffer medium increases in the speed at nozzle 230 places, even if only use middle pressure (pressure is less than 400 MPas), the speed when speed when center water jet that is enclosed with buffer medium penetrates from nozzle 230 still can reach high pressure (pressure is greater than 400 MPas).Like this, the speed of the mixed liquor in mulling chamber 210 is lower, has reduced the wear rate in mulling chamber 210, then improves gradually the speed of center water jet by contracted flow effect, has ensured the working ability of water jet machining device.
As shown in Figure 7, get the mid point of length of shaping tube 220 as initial point, the axial direction of shaping tube 220 is as y axle, the radial direction of shaping tube 220 is as x axle, set up rectangular coordinate system, be the positive direction of y axle from initial point to mulling chamber 210 directions, from initial point to nozzle, 230 directions are the negative direction of y axle.As can be seen from Figure 7, along the positive direction of y axle, the caliber of shaping tube 220 becomes greatly gradually, and the flow velocity of shaping tube 220Nei center water jet is less.Along the negative direction of y axle, the caliber of shaping tube 220 diminishes gradually, and due to mass conservation law and contracted flow effect, the flow velocity of center water jet increases gradually.
Meanwhile, because the force value of middle pressure is less than 400 MPas, therefore, and can be by suitable adjustment concentricity and pressure, ensure the long distance parcel of buffer medium centering edema with the heart involved jet, thereby reduce the wear rate of shaping tube 220.
As a kind of embodiment, the hole shape shape of nozzle 230 can be circle, rectangle, square, ellipse or triangle.Certainly, the hole shape shape of nozzle 230 can also be other shapes.More preferably, the hole shape of nozzle 230 is shaped as circle, and the shape of the outlet in mulling chamber 210 is also circular, and the internal diameter of the outlet in mulling chamber 210 is the more than 2 times of internal diameter of nozzle 230.Can ensure that like this mulling chamber 210 is with low speed ejaculation center water jet, reduce the wear rate in mulling chamber 210, nozzle 230 penetrates the center water jet that is enclosed with buffer medium with higher speed, in reducing the wear rate of nozzle 230, ensure the working ability of water jet machining device.
Preferably, the internal diameter of nozzle 230 is 1 micron-100 microns.The diameter of the nozzle 230 of general water jet machining device is more than 200 microns, and because the internal diameter of nozzle 230 is less, the wearing and tearing of nozzle 230 are just faster, and the life-span of general nozzle 230 is less than 200 hours.And in the present embodiment, because the use of buffer medium has reduced the wear rate of nozzle 230, the water jet machining device of the present embodiment can be realized the internal diameter of nozzle 230 much smaller than 200 microns, simultaneously with respect to general abrasive water-jet device, obtained prolongation the service life of nozzle 230, and it can be competed mutually with precision processing technologies such as laser.It should be noted in the discussion above that and now require to use ultra-fine abrasive material, preferably, the diameter of abrasive material is less than 30% of outgoing water jet diameter.
More preferably, the material of nozzle 230 can use tungsten carbide, diamond or jewel etc.Traditional water jet machining device, in order to reduce the wearing and tearing of nozzle 230, usually can use the nozzle material than higher-end, and as diamond, but the cost of diamond nozzle is higher.In the present embodiment, owing to having reduced the wear rate of nozzle 230, the material of nozzle will be not limited to use diamond.
