Abstract
The invention provides a derusting processing process of spring steel. The derusting processing process comprises the following operation steps: (1) infiltrating to-be-derusted spring steel into glycerinum; (2) carrying out surface polishing treatment at a rotation speed of 200r/min-300r/min by virtue of an electric water grinding wheel; (3) infiltrating the spring steel treated in the step (2) in derusting liquid for 5-10 minutes; (4) cleaning blots on the surface of the spring steel with cooled boiling water; (5) infiltrating the cleaned spring steel in a mixed water solution containing 4%-6% potassium chloride and sodium carbonate; (6) cleaning the steel spring in the step (5) at a water pressure of 7MPa-9MPa; and (7) putting the cleaned spring steel in a drying tank, and carrying out vacuum drying at a drying temperature of 50-70 DEG C. The operation of the whole process is simple, rust of the spring steel can be effectively removed, the surface of the spring steel can be effectively protected, and the reproduction of rust can be prevented; the derusting processing process can be further popularized and applied.
Description
Technical field
The present invention relates to rust cleaning technical field, be specifically related to a kind of processing of rust removing technique of spring steel.
Background technology
Present China is due to manufacturing fast development, make product made from steel in the process of producing, usually occur the situation of production capacity surplus, according to incompletely statistics, in China because annual steel production capacity surplus causes the discarded loss of getting rusty of steel, occupy about 1/4 of annual steel production, cause serious wasting phenomenon.
Spring steel refers to due to the elasticity under Quench and temper state, and be specifically designed to the steel manufacturing spring and elastic element, spring uses under shock and vibration or long-term friendship stress, so require that spring steel has high tensile strength, elastic limit, high fatigue strength, spring steel requires higher intensity and safe range of stress.But spring steel can cause surface oxidisation in the process of long-term storage, in common traditional derusting method, hand cleaning speed is slow, brain hole intensity is large, and the efficiency of rust cleaning is low, and chemical treatment makes the surface mass of spring steel structure easily change, serious toughness and the structural strength that also can affect spring steel, and the impact on environment, larger to the surface of spring steel structure of the mechanical rust removal technique of same high strength.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of processing of rust removing technique of spring steel, make the surface derusting effect of spring steel better, and not right.
For realizing above object, the present invention is achieved by the following technical programs:
A processing of rust removing technique for spring steel, operation steps is as follows:
1) by needing, the spring steel of rust cleaning infiltrates with glycerine;
2) carry out surface finish process with electric water emery wheel, rotating speed is 200-300r/min;
3) by step 2) spring steel after process is placed in rust removing solution and infiltrates 5-10min;
4) with the boiling water of cooling, the spot on spring steel surface is cleaned;
5) spring steel after cleaning is infiltrated in the aqueous solution also having 4-6% Repone K and sodium carbonate mixing;
6) by step 5) spring steel cleans with the hydraulic pressure of 7-9MPa again;
7) spring steel after cleaning is prevented vacuum-drying in loft drier, drying temperature is 50-70 DEG C.
Preferably, described step 3) in control temperature be 50-60 DEG C.
Preferably, described step 3) in the component of rust removing solution be dilute sulphuric acid 20-30%, ammonium citrate 20-30%, sodium carbonate 25-30%, trolamine 10-20%.
Preferably, described step 5) time of infiltrating is 10-15min.
Preferably, described step 7) time of drying be 2-3h.
The invention provides a kind of processing of rust removing technique of spring steel, by first carrying out the rusty stain on the removal spring steel surface of mechanical grinding in operation steps, make the surface of spring steel comparatively coarse, be convenient to contact with rust removing solution, the rusty stain of profound removal spring steel can be carried out, and the boiling water of cooling can remove the air composition in water, the air composition in water and spring steel is avoided to form rusty stain further, rust removing solution used 4-6% Repone K and sodium carbonate mixing the aqueous solution in, fine and close protective layer can be formed with spring steel, avoid contacting further with air.Whole technological operation is simple, can further genralrlization application.
