Description
前記サイドフレームの材質と固定刃及び回転刃の母材の材質は、日本工業規格で規定する炭素工具鋼鋼材、高速度工具鋼鋼材又は合金工具鋼鋼材から選ばれる鋼材であるのが望ましい。また、前記回転刃及び固定刃は、刃先が超硬合金刃先チップで形成され、該超硬合金刃先チップの幅を4〜10mmの範囲内の小さいサイズに形成することによって、超鋼合金による母材の熱膨張量への影響を少なくし、サイドフレームと回転刃及び固定刃の熱膨張量を同レベルに近づけることができて望ましい。
図面は本発明の実施形態に係るロータリーカッターを示し、図1はその要部平面図であり、図2は図1のA−A矢視拡大図である。但し、図2においては、回転刃の回転角を図1に示す状態から45°回転させた状態で示している。図3は実施例と比較例の回転刃と固定刃における刃先チップの寸法を示す要部断面拡大図であり、破線は比較例における刃先チップを示す。
従来のロータリーカッターの固定刃及び回転刃は一般にSKH系高速度工具鋼鋼材で形成され、サイドフレームはS45C鋼材等で形成されている。温度変化によるクリアランス変化は、固定刃及び回転刃とそれを支持するサイドフレームの上記材質による熱膨張率の相違によることが大きな要因となっている。そこで、本発明ではサイドフレームと刃の熱膨張変化量を同レベルにするために、サイドフレームの材質を固定刃と回転刃の母材と同程度の熱膨張率を有する材質に変更した。本発明のサイドフレーム及び固定刃10と回転刃1の母材部分1a、10aを、SKH系の高速度工具鋼材と同程度の強度及び熱膨張率を有するJIS規格で規定する炭素工具鋼鋼材、高速度工具鋼鋼材、合金工具鋼鋼材の何れかを採用した。
実施例:
固定刃及び回転刃の材質:SKH55(母材部分)+超硬合金(刃先チップ部)
固定刃の刃先チップの幅:5mm
回転刃の刃先チップの幅:5mm
サイドフレームの材質:SKH55
比較例(従来例)
固定刃及び回転刃の材質:SKH55(母材部分)+超硬合金(刃先チップ部)
固定刃の刃先チップの幅:14mm
回転刃の刃先チップの幅:13mm
サイドフレームの材質:S45C
なお、上記各材質の熱膨張係数α(×10−6/℃)は次の通りである。
超硬合金=5.5、SKH55=11.5、S45C=11.7

Claims (3)
- 回転刃と固定刃を有し、前記回転刃は、回転刃取付軸に形成した取付凹部に台座を介してボルトにより固定され、且つ前記回転刃取付軸は、その両端部をサイドフレームに設けられた軸受に回転自在に軸受され、前記固定刃は、固定刃取付台座に前記回転刃の刃先と所定のクリアランスを保つようにクリアランス調整機構を介して前記サイドフレーム間に取り付けられてなるロータリーカッターであって、前記回転刃及び前記固定刃を保持するサイドフレームの材質を前記回転刃と前記固定刃の材質と同程度の熱膨張率を有する鋼材で形成し、温度変化による回転刃と固定刃間のクリアランスの変化量を抑制したことを特徴とするロータリーカッター。
- 前記サイドフレームの材質が、日本工業規格で規定する炭素工具鋼鋼材、高速度工具鋼鋼材又は合金工具鋼鋼材から選ばれる鋼材である請求項1に記載のロータリーカッター。
- 前記回転刃及び固定刃が、刃先が超硬合金刃先チップで形成され、該超硬合金刃先チップの幅が、4〜10mmの範囲内に形成されている請求項1又は2に記載のロータリーカッター。
