Description

本発明は、刃部に模様を備えた刃物の刃部の模様形成方法に関する。 The present invention relates to a pattern forming method for a blade part of a cutter having a pattern on the blade part .

包丁やナイフ等の刃物の刃部には、例えば会社名、商標名或いは各種のマーク等の模様が表示されている。この表示方法として、刃物の刃部の表面に対し所定形状の模様を形成した刻印用工具を押圧することによって、模様を刻印する方法がある。又、刃物の刃部の表面に所定形状の模様を印刷する方法もある。さらに、刃物の刃部の表面を部分的に腐食させて凹状の模様を形成する方法もある。   A pattern such as a company name, a trade name, or various marks is displayed on a blade portion of a knife such as a knife or a knife. As this display method, there is a method of marking a pattern by pressing a marking tool having a pattern of a predetermined shape against the surface of the blade portion of the blade. There is also a method of printing a pattern with a predetermined shape on the surface of the blade part of the blade. There is also a method of forming a concave pattern by partially corroding the surface of the blade portion of the blade.

ところが、刻印用工具を用いて模様を刻印する方法は、刻印された部分の刃物の材料が凹んだ分だけ他の部位に隆起するように押し出しされることになるので、その隆起した部分を研削する後工程が必要になり、製造工程が増えて、コストを低減することができないという問題があった。又、刃部を形成する初期の段階で、その素材の表面に刻印を行う必要があるので、刻印が一種類の場合には特に工程管理上問題はないが、複数種の刻印を形成した場合には、種別の異なる各刻印ごとの刃物の後の工程管理が非常に煩わしいという問題があった。   However, the method of engraving the pattern using the engraving tool is to extrude the material of the engraved part of the blade so that it protrudes to the other part by the amount of depression, so the raised part is ground. Therefore, there is a problem that a post process is required, the manufacturing process increases, and the cost cannot be reduced. Also, since it is necessary to engrave the surface of the material at the initial stage of forming the blade, there is no problem in process control when there is only one type of marking, but when multiple types of marking are formed However, there is a problem that the process management after the blade for each type of marking is very troublesome.

一方、刃部の表面に模様を印刷する方法は、刃部の表面の研磨の時あるいは刃物の使用時に印刷された模様が剥離し易いという問題があった。
さらに、刃部の表面を部分的に腐食させて凹状の模様を形成する方法は、模様が凹んでいるため、鮮明に現われ難く、見栄えが悪いばかりでなく、刃部の表面が研磨されると、刃部の表面と凹状の模様の境界部も研磨されるので、該境界部が不鮮明となって、一層見栄えが悪くなるという問題があった。
On the other hand, the method of printing a pattern on the surface of the blade has a problem that the printed pattern is easily peeled when the surface of the blade is polished or when the blade is used.
Furthermore, the method of partially corroding the surface of the blade part to form a concave pattern is difficult to appear clearly because the pattern is recessed, and not only looks bad, but also the surface of the blade part is polished. Further, since the boundary part between the surface of the blade part and the concave pattern is also polished, there is a problem that the boundary part becomes unclear and looks worse.

本発明の目的は製造工程を少なくして、コストを低減することができるとともに、工程管理を簡素化することができ、さらに、刃部の模様の見栄を向上することができる刃物の刃部の模様形成方法を提供することにある。 The object of the present invention is to reduce the manufacturing process, reduce the cost, simplify the process management, and further improve the appearance of the cutting edge pattern . It is to provide a pattern forming method .

上記問題点を解決するために、請求項1に記載の発明は、刃芯鋼板の両外表面に複数種の金属層を積層接合したダマスカス鋼板によって形成された刃部の表面に対し、マスキング部材を接着剤により接着し、該マスキング部材の周囲の刃部の表面に腐食剤を塗布して、前記ダマスカス鋼板の表層部の複数の金属層を浸食し、前記マスキング部材を刃部の上面から分離することにより、刃部の表面に所定形状の複数の前記金属層よりなる模様を浮き彫り状に形成することを要旨とする。
請求項2記載の発明は、請求項1において、前記腐食剤は塩化第二鉄であることを要旨とする。
In order to solve the above problems, the invention according to claim 1 is directed to a masking member for the surface of a blade portion formed by a damascus steel plate in which a plurality of types of metal layers are laminated and bonded to both outer surfaces of a blade core steel plate. Are bonded with an adhesive, a corrosive agent is applied to the surface of the blade portion around the masking member, the plurality of metal layers on the surface portion of the Damascus steel plate are eroded, and the masking member is separated from the upper surface of the blade portion. By doing this, the gist is to form a pattern of a plurality of the metal layers having a predetermined shape on the surface of the blade portion in a relief shape.
The invention according to claim 2 is summarized in that, in claim 1, the corrosive agent is ferric chloride .

請求項1記載の発明によれば、刃物のダマスカス鋼板によって形成された刃部の表面に対し、マスキング部材を接着剤により接着し、該マスキング部材以外の刃部の表面に腐食剤を塗布して、前記ダマスカス鋼板の表層部の複数の金属層を浸食し、前記複数の表層部によって所定形状の模様を浮き彫り状に形成した。このため、模様の形成工程を最終段階することができ、後工程を不要にして、製造工程を少なくでき、コストを低減することができる。又、刃部に種類の異なる模様を形成する場合に、それらの刃物の工程管理を簡素化することができ、さらに、ダマスカス鋼板の複数の金属層によって模様が浮き彫り形状に形成されているので、模様の見栄を向上することができる。 According to the first aspect of the present invention, the masking member is adhered to the surface of the blade portion formed by the Damascus steel plate of the blade with an adhesive, and the corrosive agent is applied to the surface of the blade portion other than the masking member. The plurality of metal layers in the surface layer portion of the Damascus steel sheet were eroded, and a pattern having a predetermined shape was formed in a relief shape by the plurality of surface layer portions . Therefore, it is possible to the forming pattern process and the final stage, and eliminates the need for a subsequent step, can reduce the manufacturing process, the cost can be reduced. In addition, when forming different types of patterns on the blade part, the process management of those blades can be simplified, and furthermore, since the pattern is formed in a relief shape by a plurality of metal layers of the Damascus steel plate , The appearance of the pattern can be improved.

以下、本発明刃物の刃部の模様形成方法によって得られたナイフの一実施形態を図面にしたがって説明する。

The base 15 and the bottom 17 are joined and fixed to the front and rear end faces of the handle main body 13 by screwing the nut portion 17a formed integrally therewith.

図4に示すように、前記刃部12の肉厚寸法のほぼ均等の刃部本体12aの下方には、下端ほど幅狭となる切刃部12bが形成されるとともに、図1に示すように、刃部12の先端部には先鋭状の刃先12cが形成されている。前記刃部本体12aの先端部上側には、上端ほど幅狭となる面取り部12dが形成されている。   As shown in FIG. 4, a cutting blade portion 12 b that is narrower toward the lower end is formed below the blade portion main body 12 a having substantially the same thickness as the blade portion 12, and as shown in FIG. 1. A sharp blade edge 12 c is formed at the tip of the blade section 12. A chamfered portion 12d that is narrower toward the upper end is formed on the upper end of the blade portion main body 12a.

The insertion hole 15c is formed in the base end portion 12e of the blade portion 12 at a position corresponding to the insertion hole 15c of the base 15. Then, in a state where the base end portion 12e of the blade portion 12 is fitted in the groove portion 15b of the base 15, the blade 12 is connected to the base 15 through the connection pin 18 through the insertion hole 12f and the insertion hole 15c. Yes. The blade portion 12 and the base 15 are integrally connected by welding although not shown.

As a material for the blade portion 12, a nickel-damascus steel plate 20 formed by forging shown in FIG. 4 is used. This nickel-damascus steel plate 20 is formed by alternately joining a blade core steel plate 21 located in the center and a nickel layer 22 as a metal layer and a stainless steel layer 23 on both the left and right side surfaces thereof. is there. As the blade core steel plate 21, for example, super hard alloy steel in which cobalt, vanadium, and chrome are added to a base of molybdenum steel is used. The nickel layer 22 and the stainless steel layer 23 have, for example, a forged nickel damascus finish that is superimposed on 13 layers on one side and 26 layers as a whole.

前記刃部本体12aの表面には、図1及び図4に示すように浮き彫り状の模様24が形成されている。
上記模様24の形成方法について説明する。

In this state, as shown in FIG. 6A, the masking member 25 is bonded to the upper surface of the outermost stainless steel layer 23 of the blade portion 12. In this state, by applying a predetermined amount of a corrosive agent such as ferric chloride on the inside and outside of the masking member 25, the nickel layer 22 which is the two layers that are not covered by the masking member 25. The stainless steel layer 23 is corroded as shown in FIG. Thereafter, when the masking member 25 is separated from the surface of the stainless steel layer 23 that has not been eroded, a relief-shaped pattern 24 is formed as shown in FIG.
