本考案は、金属等の高速切断用超硬付丸鋸切断
機における回転刃の振れ止め装置に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a steady rest device for a rotary blade in a carbide-equipped circular saw cutting machine for high-speed cutting of metals, etc.
従来、金属等の切断に供される丸鋸切断機の回
転刃には、ハイス鋼が使用され、大径のために切
断速度が遅く、しかも刃厚が厚いために回転刃の
振れ止めを必要としなかつた。 Conventionally, high-speed steel is used for the rotary blades of circular saw cutting machines used for cutting metals, etc. Due to the large diameter, the cutting speed is slow, and the blade is thick, so a steady rest is required for the rotary blade. I couldn't help it.
しかしながら、小径の超硬付回転刃により、高
速高負荷切断とし、特に小馬力として刃厚を薄く
被切断機の歩留りの改善等省力化が要求されるよ
うになつた。 However, small-diameter carbide-equipped rotary blades are now required to perform high-speed, high-load cutting, and in particular, require low horsepower, thin blades, and labor-saving improvements such as improving the yield of cutting machines.
そのために、切断時に超硬付回転刃のビビリ等

する等の問題が生じていた。 As a result, the carbide-equipped rotary blade vibrates due to chatter during cutting, resulting in a rough cut surface, poor cutting accuracy, and significantly shortened blade life. In addition, conventionally, in order to prevent damage to the rotary blade, a soft holding piece was used to hold the rotating blade from both sides to prevent it from steadying, but when cutting metal etc. at high speed and under high load, the holding piece Problems such as damage, burning, and incomplete correction of the runout of the rotary blade have occurred.

回転刃の振れ止め装置を提供するものである。 This invention was made to solve the above-mentioned problems, and in addition to providing rigidity to the cover of the rotary blade, both sides of the rotary blade with carbide are coated with a predetermined alloy through the pressing force of a spring. The present invention provides a rotary blade steady rest device configured to prevent vibration of the rotary blade and improve cutting performance.
