Description
Technical field
The present invention relates to a kind of parts finishing strain-removing technique that is used for the auto parts and components surface smoothness.
Background technology
At present, most auto parts and components because processing technology or manufacturing environment, make easily that parts produce stain, oil mark, defective such as get rusty in different process, can't satisfy client's requirement high-quality to the part outward appearance.If by improving original processing technology or improving manufacturing environment, need to drop into a lot of time and a large amount of funds, can increase the cost of process control, but the effect of receiving may be very little.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of bright and clean effective, easy to operate, parts finishing strain-removing technique that production cost is lower is provided.
A, oil removal treatment: the rinse bath of part being put into supersonic wave cleaning machine, start supersonic wave cleaning machine, supersonic wave cleaning machine is controlled at 10～30min running time, supersonic wave cleaning machine institute ultrasonic waves transmitted FREQUENCY CONTROL is at 20～40KHz, ultrasonic power is controlled at 1.5～6KW, cleaning sink volume 90～96L; Part before the polishing will carry out thorough oil removal treatment, often adopts the method for suppersonic cleaning best results.If greasy dirt enters on the workpiece, the abrasive particle grinding force obviously weakens, grinding agent effect meeting reduction, polishing effect, decrease in efficiency, and the piece surface behind the polishing is brightless.
B, batching: in the polishing machine, put into part, abrasive particle and pure water, get again 0.01～0.03 times of pure water volume 0.01～0.02 times of LM-18 grinding agent, pure water volume, concentration is that 0.5% natrium nitrosum antirust agent adds in the polishing machine; Wherein the volume ratio of part and abrasive particle is 1:3～6, and the volume ratio of part and pure water is 1:2～3; Mainly be according to required contents such as selection or definite apparatus-form, specification of equipment, technology materials, technological parameter by the planform of polishing part, size and polishing.Engineer testing is found, part is bright and clean polished bright through polishing processing rear surface, its top layer enliven that metallic molecule is bare to be exposed to very fast oxidation blackening in the air, get rusty then, the moisture film that reason is stayed on the piece surface after cleaning has formed the necessary one deck electrolyte solution of electrochemical corrosion.Therefore when batching, can add antirust agent, prevent that part from getting rusty according to the part material specification.
C, startup polishing machine make the polishing machine rotate 30～60min, revolution rotating speed 0～180RPM;
After d, polishing finish, part and abrasive particle sorting;
E, part put into the rinse bath of supersonic wave cleaning machine, start supersonic wave cleaning machine, supersonic wave cleaning machine is controlled at 10～30min running time, supersonic wave cleaning machine institute ultrasonic waves transmitted FREQUENCY CONTROL is at 20～40KHz, ultrasonic power is controlled at 1.5～6KW, cleaning sink volume 90～96L;
Part after f, taking-up ultrasonic wave clean gets final product after the oven dry;
Finishing strain-removing technique, adopting circles round rolls mobilely, and part is fully contacted with abrasive particle, thereby stain, the oil mark of removal surface of the work, gets rusty etc., can be widely used in: the surface finishing of machinofacture, light, oxide skin eliminates rust and reduces phlegm and internal heat; The polishing of part is to obtain smooth glossy surface or to recover the metal Natural color; Foundry goods, plastic cement products remove burr; This process advantage is to reduce production costs, quality improvement, work flow are controlled, the quality assurance of constant unanimity, highly versatile.
Defectives such as technology of the present invention can efficiently eliminate stain, oil mark that part produces in different process, get rusty, infusion of financial resources is few, and is easy to operate, reduced the cost of process control widely, reaches the high-quality requirement of piece surface.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
Embodiment 1
A, oil removal treatment: the rinse bath of valve seat being put into supersonic wave cleaning machine, start supersonic wave cleaning machine, supersonic wave cleaning machine is controlled at 25～30min running time, supersonic wave cleaning machine institute ultrasonic waves transmitted FREQUENCY CONTROL is at 30～40KHz, ultrasonic intensity is controlled at 4～6KW, cleaning sink volume 90～96L;
B, batching: by volume for 1:(3～4): 2 put into fuel injector stainless steel valve seat, brown alumina grain and pure water in the polishing machine, get again 0.01～0.03 times of pure water volume 0.01～0.02 times of LM-18 grinding agent, pure water volume, concentration is that 0.5% natrium nitrosum antirust agent adds in the polishing machine;
C, startup polishing machine make the polishing machine rotate 30～40min, revolution rotating speed 150RPM;
After d, polishing finish, valve seat and brown alumina grain sorting;
E, valve seat put into the rinse bath of supersonic wave cleaning machine, start supersonic wave cleaning machine, supersonic wave cleaning machine is controlled at 25～30min running time, and supersonic wave cleaning machine institute ultrasonic waves transmitted FREQUENCY CONTROL is at 30～40Hz, ultrasonic intensity is controlled at 4～6KW, cleaning sink volume 90～96L;
