Abstract

<P>PROBLEM TO BE SOLVED: To manufacture at a low cost a composite steel sheet filled with a graphite, or a rust-proof agent with a fluidity, or a coating material therein. <P>SOLUTION: Channels 2 are formed on both surface and back surface of a steel sheet 1 at appropriate intervals by rolling, and a zinc foil 3 is placed on the surface of the steel sheet 1 on the channels 2, and the zinc foil 3 is fused on the surface of the steel sheet 1 by heating by a high frequency furnace or the like. The steel sheet 1 under this condition is immersed into the rust-proof agent with the fluidity or the coating material, and the rust-proof agent 4 or the coating material 5 is sucked into the channels 2 by a capillary phenomenon. When the composite steel sheet thus composed is press-processed and the cut face is exposed, as the exposed face is covered with the rust-proof agent 4 with the fluidity or the coating material 5, there exists no possibility of generating rust as it is intercepted from atmospheric air. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、鋼板の内部に防錆剤または塗料または黒鉛を有することにより、プレス加工の際の端面処理をプレス加工と同時に行える複合鋼板に関する。   The present invention relates to a composite steel sheet that has a rust preventive agent, a paint, or graphite inside the steel sheet, so that end face treatment during press working can be performed simultaneously with the press working.

電子機器等の筐体は、鋼板をプレス加工して形成されるものがある。鋼板をプレス加工すると、経時的に、鋼板の切断面が腐食してくる。また、カラー鋼板を用いた場合は、プレス加工すると、その切断面が素地色となり外観が見劣りするようになる。そこで、従来、鋼板の切断部からの腐食を防ぐために、特許文献１に記載の「珪素鋼板ベースプリント配線板」や、特許文献２に記載の「珪素鋼板ベース積層板」が提案されている。これらは珪素鋼板の片面に防錆金属層や絶縁層を備えたことで、プレス加工後に切断面に錆を発生することを防止することができる。
特開昭６４−５１６８９号公報 特開平１−１６８４４４号公報 Some cases of electronic equipment and the like are formed by pressing a steel plate. When a steel plate is pressed, the cut surface of the steel plate corrodes over time. Moreover, when a color steel plate is used, when it press-processes, the cut surface will become a base color and an external appearance will become inferior. Therefore, conventionally, in order to prevent corrosion from the cut portion of the steel plate, a “silicon steel plate-based printed wiring board” described in Patent Document 1 and a “silicon steel plate-based laminated board” described in Patent Document 2 have been proposed. Since these are provided with a rust-proof metal layer or an insulating layer on one side of the silicon steel plate, it is possible to prevent rust from being generated on the cut surface after press working.

しかしながら、上述した特許文献１および特許文献２に記載の珪素鋼板は、製造の際に、メッキ、蒸着、加熱等の複数の処理工程を必要として、製造設備が大型となり、製造コストが高いという問題があった。そこで本発明は、比較的簡単な製造工程で低コストに製造できる複合鋼板を提供することを目的とした。   However, the silicon steel sheets described in Patent Document 1 and Patent Document 2 described above require a plurality of processing steps such as plating, vapor deposition, and heating in the production process, resulting in a large manufacturing equipment and a high manufacturing cost. was there. Therefore, an object of the present invention is to provide a composite steel sheet that can be manufactured at a low cost by a relatively simple manufacturing process.

上記課題を解決するために、本発明に係る複合鋼板は、鋼板の片面または両面に複数の溝を形成し、該溝の上の鋼板表面に金属箔を接着し、前記溝内に黒鉛または流動性を有する防錆剤または塗料を充填して構成される。また、本発明に係る複合鋼板は、鋼板の片面または両面に適間隔で形成された溝と、該溝の上の鋼板表面に加熱溶着された亜鉛箔と、前記溝内に充填された流動性を有する防錆剤または塗料とを備える。また、本発明に係る複合鋼板は、鋼板の片面または両面に適間隔をおいて溝を形成する転造工程と、前記溝の上の鋼板表面に亜鉛箔を載せて該亜鉛箔を前記鋼板の表面に溶着する加熱溶着工程と、前記亜鉛箔が溝の上に溶着された鋼板を流動性を有する防錆剤または塗料中に浸して毛細管現象により溝内に前記防錆剤または塗料を吸引する工程とにより製造される。また、本発明に係る複合鋼板は、鋼板の片面または両面に適間隔で形成された溝と、該溝の中に充填された黒鉛と、前記溝の上の鋼板表面に加熱溶着された亜鉛箔とを備える。また、本発明に係る複合鋼板は、鋼板の片面または両面に適間隔をおいて溝を形成する転造工程と、前記鋼板の溝の中に黒鉛を充填する工程と、前記黒鉛が充填された前記溝の上の鋼板表面に亜鉛箔を載せて該亜鉛箔を前記鋼板の表面に溶着する工程とにより製造される。   In order to solve the above-mentioned problems, a composite steel sheet according to the present invention has a plurality of grooves formed on one or both surfaces of a steel sheet, a metal foil is bonded to the steel sheet surface above the grooves, and graphite or fluid flows in the grooves. It is configured by filling a rust preventive or paint having a property. Further, the composite steel sheet according to the present invention includes a groove formed at an appropriate interval on one or both surfaces of the steel sheet, a zinc foil heated and welded to the steel sheet surface above the groove, and the fluidity filled in the groove. And a rust preventive or paint. In addition, the composite steel sheet according to the present invention includes a rolling step in which grooves are formed on one or both sides of the steel sheet at appropriate intervals, and a zinc foil is placed on the steel sheet surface above the groove, and the zinc foil is attached to the steel sheet. Heat welding process for welding on the surface, and immersing the steel sheet in which the zinc foil is welded on the groove in a fluid rust preventive or paint, and sucking the rust preventive or paint into the groove by capillary action Manufactured by the process. Further, the composite steel sheet according to the present invention includes a groove formed on one or both surfaces of the steel sheet at appropriate intervals, graphite filled in the groove, and a zinc foil heated and welded to the steel sheet surface above the groove.

以上述べたように本発明によれば、鋼板表面に形成された溝内に、防錆剤または塗料または黒鉛が充填されたことにより、プレス加工時に防錆剤または塗料または黒鉛がダイやパンチに付着しそれが切断面に転写されることで、切断面に錆が発生したり色落ちすることがなくなる。また、防錆剤または塗料または黒鉛が充填された複合鋼板は、比較的簡単な製造工程で製造されるため低コストで得ることができる。   As described above, according to the present invention, the groove formed on the steel sheet surface is filled with the rust preventive agent or paint or graphite, so that the rust preventive agent or paint or graphite is applied to the die or punch during press working. When it adheres and is transferred to the cut surface, the cut surface is not rusted or discolored. In addition, a composite steel sheet filled with a rust inhibitor, paint or graphite can be obtained at a low cost because it is manufactured by a relatively simple manufacturing process.

以下、図に基づいて本発明の実施形態を説明する。図１は、溝内に防錆剤または塗料が充填される複合鋼板の構造を模式的に示した斜視図である。図中の１は鋼板であり、転造により表裏両面に適間隔で溝２が形成されている。溝２の上の鋼板１の表面に亜鉛箔３が載せられて、高周波炉等により加熱して、亜鉛箔３が鋼板１の表面に溶着されている。この状態の鋼板１を、流動性を有する防錆剤または塗料中に浸して、毛細管現象により、溝２内に防錆剤４または塗料５が吸入される。このように構成された複合鋼板は、プレス加工されて切断面が露出されると、ダイやパンチに付着した流動性を有する防錆剤４または塗料５がその露出面を覆うことになり、大気と遮断されて錆が発生することがない。また、切断面が塗料により覆われるため、色落ちすることもなくなる。この複合鋼板は、上述したように比較的簡単な工程で製造されるため、安価に提供可能である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view schematically showing the structure of a composite steel sheet in which a groove is filled with a rust inhibitor or a paint. In the figure, 1 is a steel plate, and grooves 2 are formed at appropriate intervals on both the front and back surfaces by rolling. The zinc foil 3 is placed on the surface of the steel plate 1 above the groove 2 and heated by a high frequency furnace or the like, so that the zinc foil 3 is welded to the surface of the steel plate 1. The steel plate 1 in this state is immersed in a fluid rust preventive agent or paint, and the rust preventive agent 4 or paint 5 is sucked into the groove 2 by capillary action. When the composite steel plate thus configured is pressed and the cut surface is exposed, the rust preventive agent 4 or the paint 5 having fluidity attached to the die or the punch covers the exposed surface, and the atmosphere It is cut off and rust does not occur. Further, since the cut surface is covered with the paint, the color does not fade.
