特許文献１に記載された発明は、釣針の全体にカラー塗装を行う釣針において、針先部分のみの塗装を省略することによって、針先の鋭利さが塗装によって損なわれることを防止するものである。釣針全体の表面処理を行った後に、針先を鋭利に加工するものではないため、針先をより鋭利に仕上げるものではない。特許文献２に記載された発明は、化学的に釣針の表面を溶解させるものであるが、釣針に設けた孔のバリとりを目的とするものであって、針先部分の加工を意図するものではない。 The invention described in Patent Document 1 is to prevent the sharpness of the needle tip from being damaged by the painting by omitting the painting of only the needle tip portion in the fish hook that performs color coating on the entire fish hook. . Since the tip of the needle is not sharpened after the surface treatment of the whole fishhook, the tip of the needle is not sharpened. The invention described in Patent Document 2 is intended to chemically dissolve the surface of a fishhook, but is intended to deburr a hole provided in the fishhook, and is intended to process the tip of the needle. is not.
本発明は、化学研磨を利用することによって釣針の針先をより鋭利に加工することができるとともに、黒染めの加工などの表面処理を施して表面処理の特徴、例えば黒染めの美観と表面を強固に保護する効果を備えた釣針を製造することができる新たな釣針の製造方法を提供するものである。特に、より鋭利な針先を備えた釣針、及び前記釣針の効果的な製造法を提供することを目的とするものである。 The present invention makes it possible to sharpen the tip of a fishing hook by using chemical polishing, and also provides surface treatment characteristics such as black dyeing to improve the characteristics of surface treatment, such as the aesthetics and surface of black dyeing.

It consists of a process 12, a water washing process 13, a pickling process 14, a water washing process 15, a neutralization process 16, a water washing process 17 and a drying process 18, whereas the needle after the surface treatment process 4 The pre-chemical polishing step 5 includes a degreasing step 19, a water washing step 20, a pickling step 21, a water washing step 22, a needle tip chemical polishing step 23, a water washing step 24, a neutralization step 25, and a water washing step 26. And a drying step 27.
請求項１記載の発明によれば、黒染などの表面処理を施し、該表面処理の効果を奏する釣針において、針先部分のみを化学研磨によって鋭利に加工したため、針掛かりのよい釣針を実現することができる。 According to the first aspect of the present invention, since the surface of the fish hook is subjected to surface treatment such as black dyeing and only the needle tip portion is sharply processed by chemical polishing in the fish hook having the effect of the surface treatment, a fish hook with good hooking is realized. be able to.
請求項２記載の発明によれば、焼入れ2aや焼戻し2bを行った釣針素材に、化学的に研磨する化学研磨工程４を施すことによって、釣針の成型加工などによって発生する針先のバリや曲りなどが取り除かれ、鋭利な針先の状態を実現することができる。そして、化学研磨工程を経た釣針に、黒染めや化成処理といった表面処理工程５を施すことによって、釣針素材の全体を黒染めなどの表面処理の美観や機能を付与することができる。 According to the second aspect of the present invention, by subjecting the fishhook material subjected to quenching 2a and tempering 2b to a chemical polishing step 4 for chemically polishing, burrs and bends in the needlepoint caused by the molding process of the fishhook, etc. Etc. are removed, and a sharp needle tip state can be realized. And the beauty and function of surface treatments, such as black dyeing, can be given to the whole fishhook material by giving surface treatment process 5 such as black dyeing or chemical conversion treatment to the fishhook which passed through the chemical polishing process.
表面処理のうち、例えば黒染めは、素材のわずかな表面が化学反応によって黒色の四三酸化鉄被膜に変化するもので、メッキや塗装のように素材の表面に別の被膜が形成されるものでないため、積層によって鋭利さが損なわれることがなく、なるべく針先の鋭利な形状を維持することができる。しかしながら、黒染めの表面は四三酸化鉄被膜であって研磨状態の鋭さではない。そこで、針先部分のみを化学研磨することによって四三酸化鉄被膜を取り除き、針先の鋭さを取り戻すことができる。
表面処理のうち、メッキや真空蒸着のように、被膜を付加的に形成する表面処理では、化学研磨によって被膜が取り除かれて鋭利な針先を実現することができる。
Of the surface treatments, for example, black dyeing is a process in which a slight surface of the material is changed to a black iron tetroxide film by a chemical reaction, and another film is formed on the surface of the material like plating or painting. Therefore, the sharpness is not impaired by the lamination, and the sharp shape of the needle tip can be maintained as much as possible. However, the black dyed surface is a triiron tetroxide film and is not sharply polished. Therefore, by chemically polishing only the needle tip portion, the iron tetroxide film can be removed, and the sharpness of the needle tip can be restored.
Among surface treatments, surface treatments that additionally form a film, such as plating or vacuum deposition, can remove the film by chemical polishing and realize a sharp needle tip.
請求項３記載の発明によれば、化学研磨工程の具体的な詳細工程について、焼戻し工程後の化学研磨工程３に対して、二回目の化学研磨となる針先部分化学研磨工程５において、化学研磨工程23後の水洗工程24に続けて中和工程25と、水洗工程26と、乾燥工程27で化学研磨を完了し、熱処理工程後の化学研磨工程３における酸洗い工程14及び水洗工程15を省略することによって作業を簡略化している。これは、二度目の化学研磨であるので前記工程を省略しても支障がないことが判明したためである。 According to invention of Claim 3, about the specific detailed process of a chemical polishing process, with respect to the chemical polishing process 3 after a tempering process, in the needle tip partial chemical polishing process 5 used as the second chemical polishing, Following the water washing step 24 after the polishing step 23, the chemical polishing is completed in the neutralization step 25, the water washing step 26, and the drying step 27, and the pickling step 14 and the water washing step 15 in the chemical polishing step 3 after the heat treatment step are performed. By omitting, the work is simplified. This is because it is the second chemical polishing and it has been found that there is no problem even if the process is omitted.

続く、化学研磨工程３は、釣針の表面全体を化学反応によって溶解させ表面を平滑にするものである。この化学研磨工程は、例えばHF-H2O2系の化学研磨液に接触させ表面全体を薄く溶解させる。溶解量は、数μmから数十μmとするが液濃度、処理時間によって任意に制御することができる。この化学研磨を行うことによって針先部分の先端では、溶解・研磨作用によってバリや曲りなどが取り除かれ、より鋭利な針先の状態を実現することができる。 In the subsequent chemical polishing step 3, the entire surface of the fishhook is dissolved by a chemical reaction to smooth the surface. In this chemical polishing step, for example, the entire surface is thinly dissolved by contacting with a chemical polishing solution of HF-H 2 O 2 system. The dissolution amount is from several μm to several tens of μm, but can be arbitrarily controlled depending on the liquid concentration and processing time. By performing this chemical polishing, at the tip of the needle tip portion, burrs, bends, and the like are removed by dissolution / polishing action, and a sharper needle tip state can be realized.
化学研磨工程３によって表面が平滑に処理された釣針を、化成処理や黒染めの表面処理工程４によって表面を美しく加工する。黒染めは、アルカリ黒色処理と呼ばれるものであって、例えば、35〜45％水酸化ナトリウム水溶液に硝酸ナトリウムなどの酸化剤と反応促進剤などを加えた強アルカリ溶液を約140℃に加温した液中に釣針を接触させ、釣針の表面を酸化・還元させて黒色の四三酸化鉄被膜(Fe3O4)を形成させる処理で、被膜の厚みはおよそ１〜２μm程度である。 The surface of the fishing hook whose surface has been smoothened by the chemical polishing step 3 is beautifully processed by a chemical conversion treatment or a blackening surface treatment step 4. Black dyeing is called alkali black treatment. For example, a strong alkaline solution obtained by adding an oxidizing agent such as sodium nitrate and a reaction accelerator to a 35 to 45% aqueous sodium hydroxide solution is heated to about 140 ° C. The thickness of the coating is about 1 to 2 μm by a process in which a fishhook is brought into contact with the liquid to oxidize and reduce the surface of the fishhook to form a black iron tetraoxide coating (Fe 3 O 4 ).
黒染めは、メッキや塗装のように釣針表面に被膜を積層するものではなく、釣針の材質そのものが化学反応によって変化し、形成される被膜である。図５に示すように黒染めされた釣針に防錆塗装を施し完成させることもできる。
しかしながら、黒染めされた釣針は、例え非常に薄い被膜といえども化学変化によって、四三酸化鉄被膜が表面に形成された状態であるため、針先の強靭さに欠ける可能性がある。すなわち、針の先端は四三酸化鉄で形成された被膜が表面に現れることになる。
The black dyeing is not a film formed on the surface of the fishhook like plating or painting, but is a film formed by changing the material of the fishhook itself by a chemical reaction. As shown in FIG. 5, it is also possible to complete the coating by applying a rust preventive coating to the black dyed fishhook.
However, the black-dyed fishhook, even though it is a very thin film, is in a state in which the iron tetroxide film is formed on the surface due to a chemical change, and may lack the toughness of the needle tip. That is, a coating formed of iron trioxide appears on the surface of the tip of the needle.
釣針の針先が四三酸化鉄被膜によって鋭利さを損なう可能性に対して、本発明では、図１に示すように、化成処理や黒染めされた釣針の針先部分のみを、針先部分化学研磨工程５によって、釣針の針先部分に形成された四三酸化鉄被膜を取り除く。これによって、熱処理された状態の針先部分があらわれ、より鋭利な状態を再現することができる。すなわち、化学研磨工程３によって形成された鋭利な針先を、さらに表面を除去することによって鋭利に仕上げることになる。
針先部分化学研磨工程によって鋭利な針先に仕上げられた釣針は、防錆塗装工程７によって全体に防錆塗装を施し完成される。
As shown in FIG. 1, in the present invention, as shown in FIG. 1, only the needle tip portion of the fishhook tip that has been subjected to chemical conversion treatment or black dyeing is used. In the chemical polishing step 5, the iron trioxide film formed on the tip of the fishhook is removed. As a result, a heat-treated needle tip portion appears, and a sharper state can be reproduced. That is, the sharp needle tip formed by the chemical polishing step 3 is sharpened by further removing the surface.
The fishing hook finished into a sharp needle tip by the needle tip partial chemical polishing step is completed by applying a rust preventive coating to the whole by the rust preventive coating step 7.
針先部分化学研磨工程によって研磨する針先の範囲は、特に限定されるものではないが、少なくとも黒染めによって鋭利さが損なわれる可能性がある釣針の先端を含む針先部分の範囲とし、例えばカエリのある釣針では図４(a)に示すようにカエリＤよりも先方の針先部分Ｆの範囲の針先部分化学研磨工程５によって研磨を行う。図４(b)に示すように、カエリのない釣針では、尖った針先部分Ｆを、針先部分化学研磨工程５によって研磨を行う。 The range of the needle tip to be polished by the needle tip partial chemical polishing step is not particularly limited, but is at least the range of the needle tip portion including the tip of the fish hook that may impair sharpness by black dyeing, for example, As shown in FIG. 4 (a), the fishhook with burrs is polished by the needle tip portion chemical polishing step 5 in the range of the tip portion F ahead of the burrs D. As shown in FIG. 4 (b), the sharp tip part F is polished by the tip part chemical polishing step 5 in the case of a fishing hook having no burrs.
熱処理工程２後の化学研磨工程３は、図２に示すように、脱脂工程８と、脱脂工程８の薬液を除去する水洗工程９と、表面の酸洗い工程10と、前記工程の酸を除去する水洗工程11と、化学研磨液に釣針全体を浸漬する化学研磨工程12と、前記薬液を洗浄する水洗工程13と、酸洗い工程14及びその薬液を洗浄する水洗工程15と、中和工程16と、水洗工程17及び乾燥工程18によって薬液の影響が残らない完全な化学研磨処理を行う。すなわち、図１における化学研磨工程３は、図２の工程すべてを含む工程を意味するものである。 As shown in FIG. 2, the chemical polishing step 3 after the heat treatment step 2 includes a degreasing step 8, a water washing step 9 for removing the chemical solution in the degreasing step 8, a surface pickling step 10, and an acid removal in the step. A water washing step 11, a chemical polishing step 12 for immersing the entire fishhook in the chemical polishing liquid, a water washing step 13 for washing the chemical solution, a pickling step 14 and a water washing step 15 for washing the chemical solution, and a neutralization step 16 Then, a complete chemical polishing process in which the influence of the chemical solution does not remain by the water washing process 17 and the drying process 18 is performed. That is, the chemical polishing step 3 in FIG. 1 means a step including all the steps in FIG.
黒染め加工の表面処理工程４を経た釣針は、針先のみを研磨する針先部分化学研磨工程５によって針先部分の四三酸化鉄被膜を除去する。この工程は、例えば処理溶液を収容する容器の周囲から、釣針を引っ掛けて針先部分だけを溶液に接触させるようにして実現することができる。
あるいは、針先部分だけに溶液を滴下させる他、針先部分だけに溶液を噴霧することによって実施することもできる。
In the fishing hook that has undergone the surface treatment process 4 for black dyeing, the iron trioxide film on the needle tip portion is removed by a needle tip partial chemical polishing step 5 that polishes only the needle tip. This step can be realized, for example, by hooking a fishing hook from the periphery of the container that stores the processing solution so that only the tip of the needle contacts the solution.
Alternatively, in addition to dropping the solution only on the needle tip portion, the solution can be sprayed only on the needle tip portion.
黒染めの表面処理工程４後の針先部分化学研磨工程５は、図２に示す化学研磨工程と同じ工程であってもよいが、針先部分化学研磨工程５は二回目の化学研磨でもあり、狭い範囲の処理であることに鑑み一部の工程を省略して図３の工程によって化学研磨を完了させることにより、良好な結果が得られることを見出した。
すなわち、脱脂工程19、水洗工程20、酸洗い工程21、水洗工程22、針先部分化学研磨工程23、水洗工程24、中和工程25、水洗工程26、乾燥工程27によって針先部分化学研磨工程５を完了させる。この工程では、図２に示す化学研磨工程に比較して、酸洗い工程14及び水洗工程15を省略している。
The needle tip partial chemical polishing step 5 after the black dye surface treatment step 4 may be the same as the chemical polishing step shown in FIG. 2, but the needle tip partial chemical polishing step 5 is also the second chemical polishing. In view of the narrow range of processing, it was found that good results can be obtained by omitting some of the steps and completing the chemical polishing by the steps of FIG.
That is, the needle tip partial chemical polishing step by the degreasing step 19, the water washing step 20, the pickling step 21, the water washing step 22, the needle tip partial chemical polishing step 23, the water washing step 24, the neutralization step 25, the water washing step 26, and the drying step 27 5 is completed. In this step, the pickling step 14 and the water washing step 15 are omitted as compared with the chemical polishing step shown in FIG.
前記二つの工程を省略することによって、針先部分化学研磨工程５は、先の化学研磨工程３と同じ工程で製造するよりも能率的に、釣針を製造することができる。 針先部分化学研磨工程５は、小さな部分の加工であること、二回目の加工であって基本的な処理は最初の化学研磨工程によって完了していることに鑑み、工程の簡略化が可能である。本発明者らの実験によれば、図３に示す工程によって針先部分の化学研磨において、良好な結果を得ることができた。 By omitting the two steps, the needle tip partial chemical polishing step 5 can manufacture the fishing hook more efficiently than the same step as the previous chemical polishing step 3. Needle tip partial chemical polishing process 5 is a process of a small part, and in view of the fact that it is the second process and the basic process is completed by the first chemical polishing process, the process can be simplified. is there. According to the experiments by the present inventors, good results could be obtained in the chemical polishing of the needle tip portion by the process shown in FIG.
針先部分化学研磨工程５を完了した釣針は、防錆塗装工程６によって釣針全体を防錆塗装するのが好ましい。特に、最終的に化学研磨を行った針先部分は、鋼の材質そのものが露出することになるため、防錆塗装を施す。防錆塗装として、例えばアクリルラッカー系のクリア塗料などを使用し、その厚みを数μm程度とすることによって、針先の鋭利さを損なうことなく防錆効果のある塗装を施すことができる。 The fishhook that has completed the needle tip partial chemical polishing step 5 is preferably rustproof-coated on the entire fishhook by the rustproofing coating step 6. In particular, the tip of the needle that has been finally subjected to chemical polishing is exposed to the rust-proof coating because the steel material itself is exposed. As the rust-proof coating, for example, an acrylic lacquer-based clear paint or the like is used, and by setting the thickness to about several μm, a coating having a rust-proofing effect can be applied without impairing the sharpness of the needle tip.
以上述べた、本発明に係る釣針の製造法では、黒染め加工を施す釣針において、鋭利な針先を備え魚が掛かり易い釣針を実現することができる。特に、針先部分は、その表面が四三酸化鉄被膜ではないということだけでなく、化学研磨されることによってそれだけ細く形成され、より鋭利な針先が形成されることになる。最終的に検査工程を経て、製品化される。 In the fishhook manufacturing method according to the present invention described above, the fishhook that is subjected to the black dyeing process can be realized with a sharp needlepoint and easy to catch fish. In particular, the needle tip portion is not only that the surface is not a triiron tetroxide coating, but is also made thinner by chemical polishing, and a sharper needle tip is formed. Finally, after an inspection process, it is commercialized.
