この発明は、自動車エンジン用弁ばねをはじめとする一
般コイルばねの材料となるオイルテンパー線に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an oil tempered wire that is used as a material for general coil springs including valve springs for automobile engines.

工程で製造されている。Conventional oil tempered wire is made by stripping the material wire - heat treatment -
It is manufactured using a process of wire drawing and oil tempering (continuous quenching and tempering).

の疲労強度が低下すると云う問題があった。According to the conventional manufacturing method described above, even if defects on the surface of the wire are completely removed by stripping, microscopic flaws of 20 or less are generated on the surface of the wire in the pass line from the post-process heat treatment to the oil tempering section. . Therefore, when the tensile strength of the wire is increased, there are problems in that the wire rod breaks due to the flaws during spring formation, and the fatigue strength of the manufactured spring decreases due to the flaws. Ta.

を塗布した構成となす。In order to solve the above problems, this invention mechanically or electrochemically polishes the wire surface after oil tempering treatment to remove the surface layer of the wire to a thickness of about 10 to 20 μm, and then The structure is such that a trifluoroethylene-based or a tetrafluoroethylene-based resin is coated on the surface.

If the thickness is removed by polishing, the microscopic flaws that occur on the surface layer after the peeling process will disappear.

コイリング性も従来以上に高まる。In addition, if only surface polishing is performed, the F-soa-rich surface scale produced by the heat treatment after stripping will disappear and the surface smoothness will decrease, resulting in an unavoidable decrease in coiling properties, but after polishing Because the surface is coated with trifluoroethylene resin or tetrafluoroethylene resin, which has more lubricity than F, O, rich scale,
The coiling performance is also improved more than before.

ルテンパー線を得た。The surface of the wire rod, which had been subjected to peeling, heat treatment, wire drawing, and oil tempering treatment, was electrolytically polished to remove a thickness of about 10 to 20 μI.

小疵が除去されたことによるものである。Table 1 As can be seen from this table, the oil tempered wire of the present invention has excellent fatigue properties. This is due to the removal of microscopic flaws that occur in the post-peeling process.

ながると云う効果がある。As described below, the oil tempered wire of the present invention removes microscopic flaws that occur in the post-stripping process by polishing the surface after oil tempering, and also improves the surface smoothness by eliminating the surface scale of Fo, 04 rich. Since the decrease in spring is compensated for by coating with fluorocarbon resin, it is possible to eliminate breakage during coiling due to minute flaws and decrease in fatigue strength of the spring after production, without deteriorating the coiling property. This has the effect of improving the reliability of the product and improving the yield of products during spring molding.
