Description
Technical field
The present invention relates to spring processing and manufacturing field, be specifically related to a kind of high precision spring surface
Process technique.
Background technology
Spring is exposed the most easily to be corroded, and the corrosion of spring can be divided into by its type reacted
Chemical attack and electrochemical corrosion.Chemical attack refers to that spring metal surface is the most simple and surrounding is situated between
Matter generation chemical reaction and cause spring to corrode, as raw in spring oxidation in the air being dried especially
Become oxide-film, and spring is sent out with the impurity in this liquid or this liquid in non-electrolyte liquid
Biochemical changes etc., broadly fall into chemical attack.Electrochemical corrosion refers to spring and electrolyte solution
During contact, make the corrosion that spring occurs due to the effect of micro cell, such as spring and acid or salt
During the electrolyte solution contacts such as class, owing to spring surface existing defects or impurity can form potential difference
Different electrodes, makes spring surface generation electrolysis, causes spring to corrode;And for example at spring
Time in moist atmosphere, vapor in the atmosphere can congeal into moisture film or the globule at spring surface, and
Corrosive gas in air is (in the sulfur dioxide in industrial waste gas and hydrogen sulfide or marine atmosphere
Salt fog etc.) be dissolved in moisture film or the globule and can form electrolyte, add the impurity of spring metal
Or defect forms the electrode that potential difference is different, spring generation electrolytic etching will be made.Spring is in system
Make, deposit, during use etc., often corroded by surrounding medium.Owing to spring exists
Being to play a role by elastic force during work, after spring is corroded, elastic force can change and loss of function,
Therefore prevent spring corrosion from can ensure that spring steady operation, and extend its service life.
A kind of spring table is disclosed in Chinese patent application prospectus CN 104060316 A
Face processing method, comprises the following steps: phosphatization pretreatment-washing-deionization washing from the beginning-
Electrophoretic paint electrophoresis-recovery-ultrafiltrate washes-and deionization washing-be dried-baking-curing-
Cooling.The method processes by spring carries out phosphatization and plating paint, makes spring keep relatively stable
Performance.
The shortcoming that prior art exists is: spring can produce substantial amounts of hydrogen in parkerizing process,
Therefore the spring after phosphatization has Hydrogen Brittleness Phenomena, affects the toughness of spring;And during phosphatization, work
The quality of spring is had an impact by size and the fineness of part, so this surface treatment method is not
It is applicable to the spring of high precision.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of technique simple, and antiseptic property is good,
The high precision spring surface process technique that Technological adaptability is higher.
For realizing object above, the present invention is achieved by the following technical programs:
A kind of high precision stainless steel spring process of surface treatment, step is:
(1) glazing: the spring after quenching is put into the hexagonal plating barrel equipped with brightener and coarse grained abrasive
In, roll 3-5h;
(2) degreasing, descale: taken out in hexagonal plating barrel by spring, put into added with clearly
Cleaning in the ultrasonic equipment of lotion, abluent is 1:25 with the proportioning of tap water, scavenging period
For 15-30min;
(3) washing dries up: is rinsed it with giant, re-uses tap water rinse,
Then dry up with air inducing equipment;
(4) oxidation processes: the spring after drying up put into 600-650g/L sodium hydroxide and
In the sodium nitrite mixed solution of 80~120g/L, solution is heated to 135-140 DEG C, protects
Temperature, 45-60 minute;
(5) double washings: after tap water rinse one time, reusable heat is washed one time, and hot water temperature is
90~100 DEG C, clean 1~2 minute;
(6) dry;
(7) plating paint: spring does negative electrode, applies the voltage of 70-75V, and electrophoresis time is
45-120s, uses electrophoresis method to form enamelled coating at spring surface, uses water soluble coating, paint liquid 4-5h
Circulation primary,;
(8) deoil: carry out soaking 90-150min with gasoline, then deoil with degreaser
Clean, further take out and clean with tap water;
(9) warehouse-in is dried.
Further, described high precision spring surface processes technique, in polishing step, bullet
Spring is 1:3 with the volume ratio of fine grinding material, and the consumption of brightener is the 1%--2% of spring weight.
Further, described high precision spring surface processes in technique oxidation processes, NaOH
With NaNO2Ratio be 7-9:1.
Spring is carried out upper optical processing by described process of surface treatment, just so makes spring surface
Burnishing as nickel plating.Additionally, oxidation processes relatively bonderizing, the quality shadow to spring
Ringing little, the surface being more suitable for the easy winding spring of high precision processes, and Technological adaptability is higher.
Spring aoxidizes in alkaline solution, is about the protectiveness oxygen of 0.5~1.5um at Surface Creation thickness
Change film, the material inside spring can be effectively protected, reach antioxidative effect, from
And extend the service life of high precision spring.
The invention has the beneficial effects as follows the process of surface treatment of further Optimal Spring, be allowed to suitableeer
For the anticorrosion of high precision spring, present invention process is simple, and antiseptic property is good, and technique adapts to
Property strong, can effectively extend the service life of high precision spring.
