The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
In most preferred embodiment of the present invention, the metal surface lubrication processing method comprises: material preparation step, preheating step, gas switch process, injecting step, and recycling step.
As shown in Figure 1, the present embodiment carries out surface treatment by 3 couples of one to be processed S of an injection apparatus, wherein, injection apparatus 3 has gather materials Working cabin 32, the collector 33, that is communicated with Working cabin 32 in cabin 31 of the cabin 31 that gathers materials, a connection to be located at the first nozzles 38, that the heater 34, on the cabin 31 that gathers materials is located in Working cabin 32 and to be located at the second nozzle 39 in Working cabin 32, and an exhausting assembly 5 be arranged on collector 33.
In material preparation step, most proper sphere shapes to be ground to ball B insert in the cabin 31 that gathers materials of injection apparatus 3, it is pottery, metal or glass material that the proper sphere shape grinds ball B, and the particle size range that each proper sphere shape grinds ball B is 30 μ m to 200 μ m, in the present embodiment, it is the ceramic bead that adopts particle diameter 50 μ m that the proper sphere shape grinds ball B, because the processing effect on to be processed S surface can grind the selected particle diameter of ball B and material and different along with the proper sphere shape, this part can be adjusted according to the difference of actual status of implementation, with the present embodiment exposure, is not limited to.
In preheating step, utilize heater 34 cabin 31 that will gather materials to be heated to a design temperature, and add a solid lubricant and mix with proper sphere shape grinding ball B, the scope of design temperature is Celsius below 300 ℃, solid lubricant is one or more the combination in molybdenum bisuphide, tungsten disulfide, polytetrafluoroethylene (PTFE) (Teflon), graphite, and the present embodiment is with molybdenum bisuphide (MoS
2) be example, the preset proportion that molybdenum bisuphide and proper sphere shape grind the weight of ball B is 20:1, wherein, and the design temperature in preheating step and preset proportion, be to use so that solid lubricant can be more even with proper sphere shape grinding ball B mixing, and improve the lubricity that the proper sphere shape grinds ball B simultaneously.
In the gas switch process, utilize an air compressor 35 by after the outside air compression, pass into a gas generating apparatus 36 to produce inert gas, in the present embodiment, inert gas is nitrogen, gas generating apparatus 36 is first nozzles 38 that connection one is arranged on Working cabin 32, and the cooler 37 that can reduce nitrogen temperature, wherein, cooler 37 is to be communicated with the second nozzle 39 that is arranged on Working cabin 32, and gas generating apparatus 36 is control and nitrogen is imported to the first nozzle 38 by the first valve body 61, and utilize the second valve body 62 to control simultaneously nitrogen is inputted to cooler 37, again by second nozzle 39 outputs.
In injecting step, the first nozzle 38 is connected with the cabin 31 that gathers materials, utilize the low temperature nitrogen (being the nitrogen of 0 ℃ Celsius) that second nozzle 39 is sent cooler 37 to be injected on to be processed S, make Working cabin 32 inside be the state of few oxygen, simultaneously, the normal temperature nitrogen produced with gas generating apparatus 36 again promotes to grind ball and B sprays processing, make the surface of to be processed S be ground ball B shock and form a plurality of holes 411 (as shown in Figure 2) by the proper sphere shape, produce the dust of chip in the process of clashing into, wherein, the small short slot that each hole 411 is path length 0.1 μ m ~ 1 μ m, can reach the effect that oil film keeps by the hole oil-containing.
In recycling step, to utilize grinding ball B and the expendable dust difference of proportion each other, and the attraction of cooperation exhausting assembly 5, proper sphere shape after clashing into is ground to ball B and attract to be recycled in the cabin 31 that gathers materials, and, dust attracted simultaneously and be delivered in collector 33, wherein, collector 33 has the cabin body 331 of a connection Working cabin 32, and a filter screen 332 be arranged in cabin body 331, and filter screen 332 is in order to filter the dust reclaimed.
Metal surface of the present invention lubrication processing method, compared to known metal surface treating method, can reach following some significant effect:
Metal surface of the present invention lubrication processing method be utilize the proper sphere shape grind ball B to machined part S clashed into and formed a plurality of small holes 411, make solid lubricant (molybdenum bisuphide) be attached to be processed S surface, and significantly promote the self-lubricity of to be processed S.
2. the proper sphere shape grinding ball B (being the sandblast material) due to metal surface of the present invention lubrication processing method has higher hardness and proportion, thereby in the process of processing, be not easy to produce a large amount of dust and free silica, can effectively reduce staff's suffered injury in processing, also can reduce the pollution of surrounding air simultaneously.
Metal surface of the present invention lubrication processing method be utilize the proper sphere shape grind ball B to machined part S clashed into, form most small holes 411, the proper sphere shape grinds the emitted dose of ball B and can adjust with the surface area of to be processed S, can reach the treating capacity of larger Surface Machining.
4. the proper sphere shape grinds to be processed S of ball B high-speed impact, and the surface that to be processed S is knocked produces high temperature and makes its organization softening, thereby makes inner compressed and reduce external carbuncle, and then makes it produce toughness and have higher hardness.
5. after to be processed S covering surface oil is lubricated, oil can produce oil film, and the small hole 411 because of to be processed S surface, increase friction and the absorption affinity of oil film and to be processed S, make oil film be attached to for a long time to be processed S surface and be difficult for blocking-up and there is the lubricity of height, so can avoid to be processed S and other workpiece to rub and produce abrasion.
6. because the proper sphere shape grinds ball B, be with to be processed S of high-speed impact, make to be processed S surface produce high temperature, utilize gas generating apparatus 36 and cooler 37, coordinate first and second nozzle 38,39 to import the nitrogen of normal temperature and low temperature (0 ℃) simultaneously simultaneously, make to be processed S surface there is the effect of anxious heat and chilling, it colds and heat succeed each other and can reach the effect of quenching, is conducive to the lifting of the hardness of to be processed S.
7. because import the nitrogen of low temperature (0 ℃) the airborne aqueous vapor of Working cabin 32 of can condensing, and in recycling step, aqueous vapor is taken in the cabin 31 that gathers materials, the aqueous vapor evaporation that to gather materials in cabin 31 by heater 34 preheatings again, in order to flowing of described grinding ball B, and then improve the cycle of working (machining) efficiency and use.
In sum, utilize nitrogen that the proper sphere shape is ground to ball B and spray to be processed S of shock, the surface of to be processed S forms many small holes 411 because spheric granules impacts, make the compressed granular of surface texture of to be processed S and cause external carbuncle to reduce, and to be processed S surface also has higher hardness because clashing into rear formed toughness tissue, simultaneously, to be processed the formed hole 411 in S surface, solid lubricant (molybdenum bisuphide) is improved in the adhesive force on to be processed S surface, and the increase oil content, and then promote the self-lubricity of to be processed S.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
