【産業上の利用分野】[Industrial applications]
本考案は、低速で回転しながらその外周部に形成した刃により、炭素鋼あるい はステンレス鋼等の軟質鋼材を切断する軟質鋼材切断用回転鋸に関するものであ る。 The present invention relates to a rotary saw for cutting a soft steel material, which cuts a soft steel material such as carbon steel or stainless steel by a blade formed on the outer peripheral portion while rotating at a low speed.
【0002】[0002]
【従来の技術】[Prior Art]
従来の技術として図2に示すものがあった。図2において、1は高速度工具鋼 (ハイス)により形成された軟質鋼材切断用回転鋸であり、円板状の台金2の外 周部に鋸歯形の刃部3を所定ピッチで一体に形成し、各刃部3の回転面側に切刃 4を形成してなる。 As a conventional technique, there is one shown in FIG. In FIG. 2, reference numeral 1 is a rotary saw for cutting soft steel material formed of high speed tool steel (high speed steel), and a saw-tooth shaped blade portion 3 is integrally formed on a peripheral portion of a disc-shaped base metal 2 at a predetermined pitch. The cutting edge 4 is formed on the rotation surface side of each blade 3.

【考案が解決しようとする課題】[Problems to be solved by the device]
上記従来のものは、切刃4が高速度工具鋼により形成されていたため、炭素鋼 あるいはステンレス鋼等の軟質鋼材を切断した際に、摩耗が早くなり耐久性が乏 しくなる欠点があった。これを解決するため、上記刃部3の回転面側に超硬チッ プ刃を固着することが考えられるが、この超硬チップ刃は剛性が高く摩耗し難く なるが、靱性が乏しいため振動等の衝撃によって破損し易く、上記軟質鋼材の切 断には適さないものであった。本考案は上記欠点を解消した新規な軟質鋼材切断 用回転鋸を得ることを目的とする。 Since the cutting edge 4 is formed of high-speed tool steel in the above-mentioned conventional one, there is a drawback in that when a soft steel material such as carbon steel or stainless steel is cut, wear becomes fast and durability becomes poor. In order to solve this, it is conceivable to fix a cemented carbide chip blade on the rotating surface side of the blade section 3. This cemented carbide chip blade has high rigidity and is hard to wear, but it has poor toughness, so that vibration etc. It was apt to be damaged by the impact of and was not suitable for cutting the above soft steel material. It is an object of the present invention to provide a new rotary saw for cutting soft steel materials that solves the above-mentioned drawbacks.

【課題を解決するための手段】[Means for Solving the Problems]
本考案は、上記目的を達成するために以下の如く構成したものである。即ち、 円板状の台金の外周部に鋸歯形の刃台を所定のピッチで形成し、焼結高速度工具 鋼により形成されたチップ刃を設け、該チップ刃を前記各刃台の回転面側に固着 する構成にしたものである。 The present invention is configured as follows to achieve the above object. That is, a saw-toothed blade base is formed on the outer periphery of a disk-shaped base metal at a predetermined pitch, and a chip blade made of sintered high-speed tool steel is provided, and the chip blade is rotated by each of the blade bases. It is configured to be fixed to the surface side.

【作用】 刃台に固着したチップ刃は、焼結高速度工具鋼製であるので、所定の靱性を保 持しながら従来の高速度工具鋼に比し硬度が高くなり、炭素鋼あるいはステンレ ス鋼等の軟質鋼材を切断した際に、切削性が良好になるとともに摩耗し難くなり 、また切断時の衝撃に対する折損がなくなる。[Function] Since the tip blade fixed to the tool rest is made of sintered high-speed tool steel, it has higher hardness than conventional high-speed tool steel while maintaining a certain toughness, and carbon steel or stainless steel is used. When a soft steel material such as steel is cut, it has good machinability and is less likely to be worn, and breakage due to impact during cutting is eliminated.

【実施例】【Example】
以下本考案の実施例を図面に基いて説明する。図面において、図1は本考案の 実施例を示す部分側面図である。図1において、5は軟質鋼材切断用回転鋸であ り、円盤状の台金6の外周部にチップ刃8を固着してなる。上記台金6は炭素工 具鋼(SK5)又は合金工具鋼(SKS5)により円盤状に形成するとともに、 その外周部に鋸歯形の刃台7を所定ピッチで一体に形成する。また、上記チップ 刃8は焼結高速度工具鋼(粉末ハイス)により板状に形成し、このチップ刃8を 上記各刃台7の回転面側にろう接により一体的に固着し、その回転面側を砥石に より研削して切刃8aを形成する。なお上記軟質鋼材切断用回転鋸5は切断時に おいて毎分40〜60回転で回転される。 An embodiment of the present invention will be described below with reference to the drawings. 1 is a partial side view showing an embodiment of the present invention. In FIG. 1, reference numeral 5 is a rotary saw for cutting soft steel, which is formed by fixing a tip blade 8 to the outer peripheral portion of a disc-shaped base metal 6. The base metal 6 is made of carbon tool steel (SK5) or alloy tool steel (SKS5) in a disk shape, and a saw-tooth blade base 7 is integrally formed at a predetermined pitch on the outer peripheral portion thereof. The tip blade 8 is made of sintered high-speed tool steel (powder high-speed steel) in a plate shape, and the tip blade 8 is integrally fixed to the rotating surface side of each of the blade bases 7 by brazing, and the rotation thereof is performed. The surface side is ground with a grindstone to form the cutting edge 8a. The soft steel cutting saw 5 is rotated at 40 to 60 revolutions per minute during cutting.
【0007】 上記実施例によれば、刃台7に固着したチップ刃8は、焼結高速度工具鋼製で あるので、所定の靱性を保持しながら従来の高速度工具鋼に比し硬度が高くなり 、炭素鋼あるいはステンレス鋼等の軟質鋼材を切断する際に、切削性が良好にな るとともに摩耗し難くなり、また切断時の衝撃に対する折損がなくなり、寿命が 延引することになる。また、チップ刃8を高価な焼結高速度工具鋼としても、台 金6を炭素工具鋼又は合金工具鋼等の安価な材料により形成することができるの で、コストの上昇を極力押さえることができる。According to the above-described embodiment, since the tip blade 8 fixed to the tool rest 7 is made of sintered high speed tool steel, it has a hardness higher than that of the conventional high speed tool steel while maintaining a predetermined toughness. When the soft steel material such as carbon steel or stainless steel is cut, the cutting performance is improved and it is less likely to be worn, and breakage due to impact at the time of cutting is eliminated, and the life is extended. Further, even if the tip blade 8 is made of expensive sintered high-speed tool steel, the base metal 6 can be formed of an inexpensive material such as carbon tool steel or alloy tool steel, so that an increase in cost can be suppressed as much as possible. it can.

【考案の効果】[Effect of the device]
以上の説明から明らかな如く、本考案は、台金の外周部に焼結高速度工具鋼に より形成したチップ刃を固着するようにしたので、コストの上昇を低減させなが ら、耐久性に富んだ軟質鋼材切断用回転鋸を得ることができる効果を奏する。 As is clear from the above description, in the present invention, the tip blade made of sintered high-speed tool steel is fixed to the outer periphery of the base metal, so that the durability is increased while reducing the cost increase. It is possible to obtain a rotary saw for cutting a soft steel material which is rich in water.
