Detailed description of the invention
Below, with reference to accompanying drawing, the wire rod involved by embodiment is described.In the following description, wire rod means that section shape is the bar of circle, circular, ellipse, polygon, abnormity etc.In addition, as this wire rod, be assumed to the metal of spring material, electric wire etc., but also can be nylon line, other resin-made of the glass fibre, fishing line etc. of optical fiber etc.
Wire rod involved by embodiment is by pressing on elastomer together with grinding-material and this wire rod itself or elastomeric at least either party moves and gives the wire rod of multiple groove parallel with length direction.This wire rod decreases harmful concavo-convex, and is given the fine groove of certain orientation continuously, which thereby enhances fatigue strength.
In addition, this wire rod also can be formed as, and gauge or diameter of wire is 0.6 ~ 2.8mm, the mean depth of groove is not enough gauge or diameter of wire 1/1000 and less than 10 μm.Herein, gauge or diameter of wire means the length of the part that width is the widest in the section orthogonal with the length direction of wire rod.If gauge or diameter of wire is less than Φ 0.6mm, become the break origins of fatigue fracture by the parallel groove of the length direction given energetically and be difficult to obtain effect, therefore gauge or diameter of wire can be greater than Φ 0.6mm.In addition, if gauge or diameter of wire becomes large, then when consider that wire rod processing unit (plant) described later carries out be processed as " depending on elastomeric pressing " time, processing resistance increases, and needs the gigantism of device.Consider this point, suitable device can be utilized to carry out suitable processing by the maximum diameter of applied wire rod is set to such as Φ 2.8mm.In addition, also the scope of regulation sectional area the scope of alternative above-mentioned gauge or diameter of wire can be carried out.That is, this wire rod is configured to sectional area is 0.25 ~ 8.0mm2, the mean depth of groove is not enough gauge or diameter of wire 1/1000 and also can obtain same effect less than 10 μm.In addition, the mean depth of groove refers to 10 mean roughness represented with JISB0601-1994.
In addition, the mode of the diameter of grinding-material is 100 ~ 300 μm, and this grinding-material also can be utilized to form this wire rod.In addition, the diameter of grinding-material is the diameter utilizing the method employing with JISR6010 the screen cloth being standard to obtain.In addition, " mode " refers to the value becoming crest in size distribution, depends on the mesh of standard screen cloth JISZ8801.If use the less grinding-material less than 100 μm, although the surface roughness grainding capacity that then can reduce wire surface is poor, the grinding-material of more than 100 μm therefore can be used.In addition, if use the grinding-material more than 300 μm, there is the situation that surface roughness change generates greatly new break origins, therefore can use the grinding-material of less than 300 μm.In addition, the average diameter of grinding-material is about 125 ~ 250 μm.
In addition, grinding-material also can comprise at least one in carborundum, aluminium oxide, garnet, diamond.
In addition, the hardness of this wire rod is 10 ~ 68HRc (the C scale of Rockwell hardness), and the hardness of grinding-material also can be greater than the hardness of this wire rod.In the method for the elastomeric pressing of the wire rod processing unit (plant) stated after a procedure less than the wire rod of the softness of HRc10, there is the worry producing broken string because processing resistance.In addition, really up to the mark more than the wire rod of HRc68, there is the situation that cannot generate the face playing effect in the processing method of the wire rod processing unit (plant) stated after a procedure.In addition, this scope is equivalent to Hv190 ~ 940 of Vickers hardness.
In addition, the material of this wire rod also can be any one in high-carbon steel, stainless steel, copper alloy, titanium alloy, tungsten alloy.
In addition, the area of the slot part formed by grinding-material in the surface of this wire rod also can relative to the entirety of the area on the surface of this wire rod more than 75%." area of the slot part formed by grinding-material in the surface of this wire rod relative to the entirety of the area on the surface of this wire rod more than 75% " means and does not utilize grinding agent to form groove, remain the region of scar relative to the state of whole region less than 25%.Such as, relative to the surface configuration of original (before the mold aft-loaded airfoil) shown in Figure 19 (a), the surface configuration after processing becomes Figure 19 (b).In Figure 19 (b), represent that having utilized grinding-material to carry out processes the part, the i.e. slot part that process by the part that Gr represents.On the other hand, undressed part, namely remaining scar part is represented by the part that Un represents.In other words, above-mentioned record means that the value (Gr/ (Gr+Un)) obtained divided by the summation of Gr and Un by the summation of Gr is more than 75%.Below, " area of the slot part formed by grinding-material in the surface of wire rod is relative to the ratio of whole surface area " that represent by value (Gr/ (Gr+Un)) is called " coverage rate ".In addition, Figure 19 (b) represents that coverage rate is the state of about 50%, therefore, processes in fact further, the suitable state that the region becoming Gr increases.
Above, the wire rod tool involved by embodiment has the following advantages: form various shape on the surface of wire rod and reduce harmful depression that can become break origins, improving fatigue strength thus.And then, when when wire rod length direction to more than 75% of wire rod circumference region give the groove of sequential like, there is the torsion relative to wire rod and reduce the depression of harmful circumferencial direction further, the advantage that fatigue strength improves further.
And then the identical groove given continuously on the length direction of wire rod, can reduce the coefficient of friction of wire rod according to its shape.Therefore, when utilizing spiral etc. to add man-hour to wire rod, obtaining and will process resistance suppression for less, the effect of the burn of blade etc. can be suppressed.
In addition, by processing wire rod at equidirectional, the Plastic Flow layer of fixed-direction is formed in the pole nearby layers on surface.Therefore, obtain according to the material of wire rod and improve the such effect of corrosion resistance.
But, for the identical groove given continuously on the length direction of wire rod, be imparted to the region of the entirety of wire rod circumference, then more can play its effect.But, consider that when region (area) of the entirety this groove being imparted to wire rod circumference machining period increases the continuous asymptotic this point of effect of the situation that the state of this point and the region state of giving this groove to about 75% of wire rod circumference and the region of the ratio to more than 75% giving this groove compares and is set to suitable state.That is, when to more than 75% of wire rod circumference region give the groove in sequential like on the length direction of wire rod, there is the effect obtaining enough fatigue strength etc. with suitable machining period.
In addition, if the groove existed in sequential like on the length direction of wire rod is crossed deeply, the situation of break origins is become on the contrary, therefore, groove depth also can not enough gauge or diameter of wire 1/1000, in addition, in the thicker wire rod of more than diameter 4mm, groove depth also can less than 10 μm.Thereby, it is possible to obtain suitable fatigue strength.
In addition, for giving the elastomer of groove as be formed as banded or roll, also can be configured to make by rotating to conjugate with the contact site of wire rod.According to this structure, the consumption of elastomer itself dispersion and favourable.In addition, elastomer also can make block component reciprocate.
In addition, for giving the grinding-material of groove, as long as the monomer of such as aluminium oxide, pottery, glass dust, silica flour, metal powder etc. or mixture.In addition, the grinding-material material that the hardness of hardness ratio wire rod also can be adopted hard.In addition, as long as grinding-material can carry out the material of machining by effects on surface.
As mentioned above, according to being pressed into together with grinding-material in elastomer and this wire rod itself or elastomeric at least either party moves and the wire rod that formed, the harmful concavo-convex minimizing being present in wire surface can being realized, improve the fatigue strength of wire rod.Such as gauge or diameter of wire is 0.6 ~ 2.8mm, have and be formed with multiple parallel groove at length direction, the mean depth of this groove not enough 1/1000 of gauge or diameter of wire and the wire rod less than 10 μm, can realize the harmful concavo-convex minimizing being present in wire surface, improve the fatigue strength of wire rod.Further, the life-time dilatation of the various parts of the spiral parts employing this wire rod etc. can be realized.
Then, the method manufacturing above-mentioned wire rod is described.Method for manufacturing wire involved by embodiment is that the surface that effects on surface has a wire rod of scar carries out processing and manufactures the method for manufacturing wire of the wire rod that improve fatigue strength.In the method, wire rod is pressed in elastomer together with grinding-material, wire rod or elastomeric at least either party length direction along wire rod are moved, give the groove parallel with length direction to wire rod thus.In addition, before above-mentioned processing, make it by mold to adjust gauge or diameter of wire, in other words, above-mentioned " surface has the wire rod of scar " be by mold after wire rod.
In addition, in this method for manufacturing wire, elastomer at least arranges a pair so that wire gripper, the relative velocity in the longitudinal direction between wire rod and elastomer can be set to more than 40m/ minute.
Above, the method for manufacturing wire involved by embodiment, can realize harmful concavo-convex minimizing on the surface being present in obtained wire rod, improve the fatigue strength of wire rod.Further, the life-time dilatation of the various parts of the spiral parts employing this wire rod etc. can be realized.According to the method, can obtain utilization employ powder (grinding-material) machining effects on surface entirety carried out the wire rod of even processing.The chemicals that the method does not use pickling etc. to use, therefore, it is possible to significantly reduce carrying capacity of environment.In the method, the feature structure identical with the content illustrated in above-mentioned wire rod is also effective, can obtain identical effect.
