Description
Technical field
The present invention relates to the oil temper wire that uses as starting material such as the valve spring of oil engine or bridge joint springs, relate in particular to the oilness of in spring processing, improving significantly between material and the instrument, thereby can seek the manufacture method of oil temper wire of the raising of spring productivity and spring precision.
Background technology
Concerning the wire rod that the starting material as above-mentioned various springs use, generally be that enforcement is called as oil-tempered Q-tempering thermal treatment and finishes processing after the process Wire Drawing.But because the wire rod that produces like this need be shaped and spring by reeling, therefore in above-mentioned processing, the oilness between spring and the machining tool is well extremely important for improving its productivity.
As adding the technology that improves oilness man-hour in that oil temper wire is reeled, existing up to now a lot of methods, below as wherein typical example, enumerated following (1)～(3).
(1) composition, thickness and the connecting airtight property of the oxide skin that will generate on the surface of oil temper wire are managed into suitable value, form the method (for example, special fair 5-No. 14771 communiques) of the good oxide film thereon of processibility
(2) substitute slushing oil, the lubricating oil that will have a rust-preventing characteristic is coated in the method on the tempered steel wire.
(3) thickness of the oxide skin that will generate on the surface of tempered steel wire is managed into below a certain appointed thickness, method as auxiliary coiling, formation is the method (for example, speciallyying permit communique No. 3003831) as the plating tunicles such as resin of main body with Synolac, amino acid.
On the other hand, as the oil temper wire of the valve spring that is used in bike etc., thinking in recent years needs the following expectation of reply.
(1), has the tendency that wire intensity is carried out more high strength, thinner footpathization and used under high design stress for corresponding with the lightweight requirements of bike.
(2) for spring being set and guaranteeing necessary stroke (stroke), also increased for example use of the special crosssection line of elliptical shape in narrower space.And, in the coiling processing of this special crosssection line,, need the wire rod rotation in the strict control winding process for guaranteeing necessary spring precision.
Especially in recent years, be accompanied by high performance, lightweight requirements to spring, the spring shape also is formed the design that can use under high bearing strength test, and need more use hard material under the high strength under many circumstances, produces the big spring of amount of plastic deformation in spring processing.
As concrete judgement criteria, when with ratio (D/d) expression of the mean diameter (D) of spring and line footpath d, needs are a kind of to have this than less than 3.5 the spring diameter and the big spring of pitch of spring.
Add man-hour in that such spring is reeled, because the heating in friction between material and the instrument and the processing, the interface temperature between material and the instrument rises.Add man-hour reeling, though guaranteed good processibility by the coating of oxide film thereon that is formed at wire surface and slushing oil, but the thermotolerance of lubricated tunicle is insufficient in such lubricating system, easily and instrument between cause adhesion wear, cause being difficult to the spring of effective production regulation shape.
In addition, make when the wire rod that uses special crosssection under the situation of spring,, need to use the little guiding piece or the pin in a plurality of gaps to fix, reel again for guaranteeing its precision well.In addition, used high-strength wire material and be that the spring of the wire rod of special crosssection is also increasing.
Under such situation, only depend on the oxide film thereon and the slushing oil on oil temper wire surface in the past, the lubricant effect that is brought by slushing oil becomes so not big sometimes, and then has following unreasonable situation sometimes.
(1) reels coilings such as pin or guiding piece with the oilness deficiency between instrument and the metal wire surface, cause that easily burning is sticking, cause shorten life tools.Therefore, need stop power operation and carry out instrument exchange or repairing etc., cause productivity to descend.
(2) if take place to burn sticking, then can produce as the diameter of the spring of goods or free length (the spring length when not having load) uneven, thereby goods deterioration in accuracy and goods decrease in yield.
(3) in addition, the sticking harmful flaw that can produce wire on the spring surface of such burning is to the spring life bad influence of taking.
Summary of the invention
The present invention is in view of the above fact, its purpose is to provide a kind of and can gives sufficient thermotolerance and guarantee good lubricity to lubricated tunicle, and also can guarantee the oil temper wire of good coiling in the oil temper wire of high-strength metal line or special crosssection.
For achieving the above object, the invention provides a kind of oil temper wire, it will be intended to, and forms by rete at wire surface, and this is made of more than one the inorganic salt of selecting from constitute with vitriol, silicate and borate a group by rete.
Inorganic salt in the described tunicle can use more than one that select from be made of water glass, potassium silicate, Magnesium Silicate q-agent, sodium sulfate, vitriolate of tartar, Sodium Tetraborate and potassium borate one group.
In oil temper wire of the present invention, preferably constitute by inorganic salt by rete in also contain lubricant component and/or the soap alkali composition that possesses oilness as required.
As the lubricant component that contains in the tunicle this moment, can enumerate with the petroleum wax is the wax class of representative, and as described soap alkali composition, can enumerate more than one that select from stearic acid, palmitinic acid, oleic acid, linolic acid and linolenic sodium salt or sylvite.In addition, under the situation that contains lubricant component and/or soap alkali composition, the amount of described lubricant component that contains in tunicle and/or soap alkali composition is 5～50 quality %.
In oil temper wire of the present invention, be preferably in described tunicle surface and also apply slushing oil as required, can improve the rust-preventing characteristic of oil temper wire thus.
On the other hand, when making oil temper wire of the present invention, optimal way is, also contain as required in the aqueous solution of the one or more kinds of inorganic salt of in a group of constituting, selecting or except described inorganic salt in the aqueous solution of lubricant component with oilness and/or soap alkali composition by vitriol, silicate and borate, forming the described aqueous solution by the impregnation oils tempered steel wire at wire surface films, then carry out drying and remove, form the oilness tunicle at wire surface by the moisture content during the aqueous solution is filmed.In the method, preferred 1.5～30 quality % of the solid component concentration in the described aqueous solution plated film.
Embodiment
Present inventors are from improving spring with oilness the coiling of oil temper wire and stable on heating viewpoint, sticking method is investigated and result of experiment has been found to preventing to burn, by adopting above-mentioned formation to achieve the above object fully, and then finished the present invention.
Metal wire in the processing of present spring and the lubricating structure between the instrument be, based on the oxide film thereon on the line surface that generates in the oil temper wire manufacturing processed be coated in the oilness that the lip-deep slushing oil of line possessed of present goods and realize.On the other hand, for the requirement of the high precision int of high strength, special crosssection linearize or the goods of oil temper wire and the productive requirement etc. that improves high-speed winding, only the countermeasure that improves oilness by slushing oil seems abundant inadequately.
In addition, oxide film thereon for the line surface, for with slushing oil between retentivity or in order to relax direct contact the between the DO-IT-YOURSELF DIY, need possess a certain degree by film thickness, if but thickness is excessive, the connecting airtight property variation of oxide film thereon then, and inappropriate situation that tunicle is peeled off before the pin of reeling is arranged.Inappropriate situation like this can cause the reduction of coiling property.
Therefore, be necessary that gauge control with oxide film is at suitable thickness, thereby proposed the method (for example, described special fair 5-No. 14771 communiques) of controlled oxidation tunicle, but fully correspondence requires the requirement that improves of the oilness of the more and more higher coiling of characteristic in processing.
For such requirement, present inventors have obtained following design, that is, will cut apart in the following manner in the function that the oxide film thereon in the processing of reeling and slushing oil are taken on, and the composition of the tunicle that is formed at the spring surface carried out suitable control, to enable to give these functions.
(a) the direct metallic contact between instruments such as pin and the material (line surface) is carried out the demulcent function
(b) slushing oil had, reduce function as the frictional coefficient of lubricating oil
(c) give the effect of wire rod as slushing oil
