Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は高圧ホース押し切り用刃物に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a cutter for pushing off a high-pressure hose.
詳しくはアラミツド繊維＆維で補強されたゴムホースの
裁断用刃物に係るものである。More specifically, it relates to a cutting tool for cutting rubber hoses reinforced with aramid fibers and fibers.
［従来の技術］
従来アラミツド繊維で補強された高圧用ゴムホースを裁

殊な！新方法となりその設備は非常に大規模になり連続
工程の中で多数個の裁断工程を設ける事が困難であった
。[Prior Art] Conventionally, high-pressure rubber hoses reinforced with aramid fibers cannot be cut using ordinary metal shearing force. Therefore, special equipment such as rotating blades and water jets! This was a new method, and the equipment required was very large, making it difficult to set up multiple cutting processes in a continuous process.
そこで高強力のアラミツド繊維で補強されたゴムホース
を押し切りで裁断し、優れた耐久性を有する刃物の出現
が求められている。Therefore, there is a need for a cutting tool that can cut rubber hoses reinforced with high-strength aramid fibers and has excellent durability.
［発明が解決しようとする問題点］
本発明は、上記した問題点の解消を企図して案出された
ものであり、押し切り裁断用の刃物を提供することを目
的とするものである。[Problems to be Solved by the Invention] The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a cutter for push cutting.
［問題点を解決するための手段］
本発明の高圧ホース押し切り用刃物は、一端部にセラミ
ックス製の刃部をもつ０．７５〜１．ＯＩの厚さの薄板
形状であり、該刃部は先端部の第１刃部と該先端部に続
く第２刃部の二段形状で、刃先面で形成する刃面角度は
該第１刃部が３５〜４５度、該第２刃部がＩＴＩ刃部よ
り鋭角であることを特徴とするものである。[Means for Solving the Problems] The high-pressure hose push-cutting knife of the present invention has a blade made of ceramics at one end and has a diameter of 0.75 to 1.5 mm. It has a thin plate shape with a thickness of OI, and the blade part has a two-step shape with a first blade part at the tip and a second blade part following the tip part, and the blade surface angle formed by the blade edge surface is the same as the first blade part. It is characterized in that the second blade part is at a more acute angle than the ITI blade part.
この刃物は少なくとも刃部がセラミックスで構成されて
いる。セラミックスとしては部分安定化ジルコニア等公
知の構造用ファインセラミックスを利用できる。At least the blade portion of this knife is made of ceramics. As the ceramic, known structural fine ceramics such as partially stabilized zirconia can be used.
上記の刃物の形状は、０．７５〜１．０１１０１の厚さ

て適宜法められる。本発明の刃部は二段月形状を有し先
端部の第１刃部が、刃先面で形成する刃面の角度が３５
〜４５度である。刃面の角度が３５度未満であると裁断
時に刃こぼれを起す等刃先の破損をおこし好ましくない
。また４５度を超えると切れ味が悪くなり押し切り刃物
として好ましくない。The shape of the above-mentioned cutter is a thin plate having a thickness of 0.75 to 1.01101 mm, and the outer dimensions are determined as appropriate depending on the hose to be cut. The blade portion of the present invention has a two-step moon shape, and the first blade portion at the tip has a blade surface angle of 35
~45 degrees. If the angle of the blade surface is less than 35 degrees, it is not preferable because it will cause damage to the blade edge such as blade spillage during cutting. Moreover, if it exceeds 45 degrees, the sharpness becomes poor and it is not preferable as a push-cut knife.
刃部の先端部に続く第２刃部を設けたのは、第２刃部を
第１刃部より厚さを薄くしてホースの逃げを少なくする
ためのものである。従って第２刃部の面角度は第１刃部
よりも鋭角であることが必要である。The reason for providing the second blade part following the tip of the blade part is to make the second blade part thinner than the first blade part so as to reduce the escape of the hose. Therefore, it is necessary that the surface angle of the second blade part is more acute than that of the first blade part.
第２刃部の面角度は第１刃部よりも５〜１０度鋭角であ
ることが好ましい。It is preferable that the surface angle of the second blade part is 5 to 10 degrees more acute than that of the first blade part.
この刃物を用いて高圧ホースを裁断するには、横方向に
配置した高圧ホースの裁断箇所に対して９０度上部の位
置より該刃物を押し下げて押し切りによって切断する。In order to cut a high-pressure hose using this cutter, the cutter is pushed down from a position 90 degrees above the cutting point of the high-pressure hose arranged in the horizontal direction, and the cutter is cut by pushing.
高圧ホースの受は台には刃厚より大きめのスリットが設
けられ、刃先部が受は台に当らずスリット部に押し下げ
られて刃先が保護されるようにするのが好ましい。It is preferable that a slit larger than the blade thickness be provided in the stand of the high-pressure hose receiver so that the edge of the blade does not hit the stand and is pushed down into the slit to protect the blade edge.
刃物を駆動する装ａとしては刃物を一定方向に往復動す
る油圧装機、機械装置を使用することができる。As the device a for driving the cutter, a hydraulic device or a mechanical device that reciprocates the cutter in a fixed direction can be used.

A hose with a two-stage shape, the first blade part has a blade surface angle of 35 to 45 degrees, and the second blade part has a blade surface angle more acute than the first blade part, and is reinforced with strong fibers such as aramid fibers. Cutting has become easier. That is, the high-pressure hose can be cut simply by moving the knife up and down at right angles to the high-pressure hose. Therefore, the equipment required for cutting is compact and simple compared to rotary blades, water jets, etc., and has the advantage that it can be easily introduced into continuous processes.

The life of the cutting blade has been significantly extended, making it a highly durable knife.
