Description
[technical field]
The present invention relates to the abrasion-resistant metal technical field, specifically a kind of abrasion resistant pretreatment process of metallic article.
[background technology]
In mechanical industry, no matter its goods use material how good, and how accurate machining accuracy is, and examine under a microscope the metal surface, and always cloth is all over pit and slit, and this is to produce basic cause of wear.
The dry friction phenomenon of machinery industry is found everywhere, and this is extremely harmful, and antiwear additive can effectively improve this marginal lubricating status, improves the quality of metallic article.
Traditional method is that antiwear additive is added in the lubricating oil in certain proportion, and is that carrier takes on the friction point with oil, thereby reaches the purpose of anti-attrition.This method not only cost is high but also take effect very slow.Because most process line, often adopt the mode of centralized lubrication, the machine oil in fuel tank is measurement unit with the ton, the effect that antiwear additive has been diluted in the lubricating oil desalination of flood tide causes and expends very highly, makes most producer only use lubricating oil and without antiwear additive.
Along with developing rapidly of nanosecond science and technology, can adopt the particulate anti-friction material, fill up the surface crater of friction pair, the temperature that this process need is certain.
[summary of the invention]
The objective of the invention is in order to overcome the deficiencies in the prior art, adopt pretreatment mode, use heat activated mode, make the direct impermeable surface of wear-resistant particulate, the coefficient of friction of change metal surface and the abrasion resistant pretreatment process of a kind of metallic article of designing.
For achieving the above object, the abrasion resistant pretreatment process of a kind of metallic article of design, its processing step is: (1) metal material preliminary treatment: clean the metallic article surface clean that need are handled; (2) be coated with antiwear additive: antiwear additive is evenly spread upon the metal surface, and described antiwear additive is the oil-based liquid material, its physical and chemical parameter be flash-point greater than 180 ℃, 1 grade of copper corrosion, kinematic viscosity is greater than 10mm under 100 ℃
2/ S, terraced nurse agree antiwear characteristics greater than 80 pounds; (3) baking: the metal that will coat antiwear additive is put into baking oven, and temperature is 50 ℃-130 ℃, and the time is 15-120 minute; (4) soak antiwear additive: take out the metallic article in the baking oven, immerse in the antiwear additive while hot; (5) get finished product: the metallic article that will immerse in the antiwear additive is cooled to take out drip-dry behind the normal temperature, gets product.Described processing step repeats 1-3 time.
The present invention compares with prior art, has prolonged the service life of metallic article, has improved machining accuracy, has reduced noise, has reduced spillage of material, energy savings, and technology is simple, and effect is remarkable, and is pollution-free.
[specific embodiment]
Below the present invention is further illustrated, the present invention is still more clearly concerning those skilled in the art.
Employed antiwear additive is generally selected for use environmentally friendly among the present invention, can decompose, clean easily, the oil-based liquid material that easy infiltration is not run off, require flash-point (opening)＞180 ℃ according to the GB GB/T3536-1983 method of inspection, according to 100 ℃ of GB GB/T5096-1985 method of inspection requirements, 1 grade of 3h copper corrosion, require 100 ℃ of following kinematic viscosity＞10mm according to the GB GB/T265-1988 method of inspection
2/ S, terraced nurse agree antiwear characteristics＞80 pound, and liquid does not have layering, and is transparent limpid, free from extraneous odour, and the more little effect of particle diameter is good more, so all use the full synthetic oil antiwear additive in following examples.
Example 1.
Be used on crankshaft two end hole machine tool and the tapping machine, screw tap is wherein used oily cleansing agent wipe surfaces earlier, and then it is dried to use cloth to wipe with, make the no dirt oil stain in surface, then the full synthetic oil antiwear additive is evenly spread upon the screw tap surface, then screw tap was heated 1 hour with 50-80 ℃ in baking oven, take out back dip-coating at once antiwear additive, be cooled to take out behind the normal temperature, drip-dry can be used.Obviously improve through the screw tap wearability after this PROCESS FOR TREATMENT.Below be to use this PROCESS FOR TREATMENT operating position of screw tap later.

Add up to hundred of 260-9211 to consume 1.80 1.86 1.60
Compared with 2004, the screw tap durability has improved 30% on the crankshaft two end hole machine tool, and the screw tap durability has reduced 19.3% on tapping machine, amounts to hundred consumption of screw tap and has reduced by 11.1%.
Example 2.
Be used on the back-shaped milling cutter, earlier with oily cleansing agent wipe surfaces, and then it is dried to use cloth to wipe with, make the no dirt oil stain in surface, then the full synthetic oil antiwear additive is evenly spread upon the milling cutter surface, put into baking oven again, take out the back and immerse in the antiwear additive at once with 120 ℃ of heating 30 minutes, be cooled to take out behind the normal temperature, drip-dry can be used.But the 600-700 of the every handle groove milling of the milling cutter of PROCESS FOR TREATMENT in the past bar, use technology of the present invention after, but every 3000 of milling cutter groove millings.
Example 3.
Various micromachine rotating speeds are generally 2000-20000 to be changeed more, for big or small industrial equipment, household electrical appliance supporting.Limit because of cost and product requirement, have larger amt to adopt oiliness bearing in the motor bearings.But there is the problem that the life-span is short, noise is big in oiliness bearing.After work about 1000 hours, because of the wearing and tearing of bearing and axle, the gap increases, and noise and vibration are obviously risen, indivedual motor bearings even cause seize stuck and burn out motor.They once tried out multiple way and improved on oiliness bearing, all can not reach effect preferably.With motor bearings by after the above-mentioned PROCESS FOR TREATMENT in baking oven with 130 ℃ of heating after 1 hour, putting into antiwear additive is cooled to take out behind the normal temperature, drip-dry is used, for stiffening effect, also above-mentioned steps can be repeated 2-3 time again, so handle rear motor and also can remain in the critical field after 2000 hours in work.
Example 4.
The reduction gearing motor that various office equipment are supporting, to the noise of product with specific (special) requirements is arranged service life, particularly the noise of gear reduction box part is the most responsive hard nut to crack, to electric current, torque, the power consumption of motor under different operating modes such as zero load, peak efficiency and peak power, strict requirement is arranged all also simultaneously.In all links, the quality of gear-box becomes key factor.When producing each parts of gear-box, also meet the requirements during some product export, work a period of time has just exceeded standard, and some can only accomplish that part is up to standard.Gear-box by after the above-mentioned PROCESS FOR TREATMENT, after putting into antiwear additive after 2 hours and be cooled to normal temperature with 100 ℃ of heating in baking oven, is taken out drip-dry and uses,, make product reach requirement through long-time tracking and testing.
