Description

【0001】
【発明の属する技術分野】
本発明は、ハニカムコアの加工方法に関する。すなわちハニカムコアについて、その開口端面を例えば曲面に削り加工する、加工方法に関するものである。
【0002】
【従来の技術】
中空柱状のセルの平面的集合体よりなるハニカムコアについて、その開口端面を、例えば3次曲面等の所定形状に削り加工する場合、従来一般的には、NC加工が採用されていた。すなわち、ハニカムコアに対する切削工具の位置,送り量,削り量,角度,方向,速度等を選択・指示する数値データを、予めプログラミングしておき、もって、このようなプログラミング情報に基づき、演算機構やサーボ機構を介して切削工具の動作を自動制御し、もってハニカムコアの開口端面を所定形状に削り加工していた。
【0003】
【発明が解決しようとする課題】
ところで、このような従来例にあっては、次の問題が指摘されていた。まず第1に、ハニカムコアの曲面等の所定形状への削り加工は、従来、上述したようにNC加工にて実施されていたので、まず、プログラミングに予め時間を要し、又、実際の削り加工に先立ちダミーを使ったテスト加工が、実証のため必要であり、この面からも時間を要していた。更に、いわゆる展張法にて製造されたハニカムコアは、特に構造上剥がれやすい上に、柔性を帯びているので圧縮されやすく位置決め保持しにくいので、実際の削り加工は約2mm程度ずつしか実施できないと共に、その送り速度も遅く設定されていた。もってこれらに起因し、ハニカムコアの所定形状への削り加工は、従来、プログラミングから削り加工完了まで非常に長時間を要し、日単位の作業となり日数もかかる等、時間面・期間面に問題が指摘されていた。
【0004】
第2に、同様にハニカムコアの曲面等の所定形状への削り加工は、従来、NC加工にて実施されていたので、まず、プログラミング作業を要し、又、実際の削り加工に先立ちテスト加工作業が必要であり、ダミーのハニカムコアを供することも必要であった。更に、ハニカムコアは構造上剥がれやすい上に、柔性を帯びているので圧縮されやすく位置決め保持しにくいので、実際の削り加工も時間をかけ慎重に実施されていた。もってこれらに起因し、ハニカムコアの所定形状への削り加工は従来、非常に割高となる等、コスト面にも問題が指摘されていた。
【0005】
本発明は、このような実情に鑑み、上記従来例における課題を解決すべくなされたものであって、請求項1では、所定の当板とガイドプレートを固定的に取付けてから、切削刃にて削り加工するようにしたことにより、請求項2では、所定の底板やガイド治具を固定的に取付け,立設してから、トレーサーを介し刃物にて削り加工するようにしたことにより、第1に、時間面・期間面に優れると共に、第2に、コスト面にも優れた、ハニカムコアの加工方法を提案することを目的とする。
【0006】
【課題を解決するための手段】
このような課題を解決する本発明の技術的手段は、次のとおりである。まず、請求項1については次のとおり。すなわち、このハニカムコアの加工方法は、中空柱状の多数のセルの平面的集合体よりなり、全体形状が四角柱体状をなし、セル軸方向の平坦な両開口端面と、該開口端面に対し直角をなすセル軸方向に沿った平坦な両端面と、を備えたハニカムコアについて、一方の該開口端面側を所定形状に削り加工する方法に関する。そしてこの加工方法では、まず、該ハニカムコアの他方の該開口端面に、見合った大きさの当板を固定的に取付けると共に、該当板の端および該ハニカムコアのセル軸方向に沿った該端面に、所定形状のガイドが形成されたガイドプレートを固定的に取付ける。それから切削刃を用い、該ガイドプレートのガイドにて案内せしめつつ、セル軸方向と直交する方向から、該ハニカムコアの一方の該開口端面側を所定形状に削り加工する。なお事後、加工された該ハニカムコアから、該当板,ガイドプレート等が除去される。
【0007】
次に、請求項2については次のとおり。すなわち、このハニカムコアの加工方法は、中空柱状の多数のセルの平面的集合体よりなり、全体形状が四角柱体状をなし、セル軸方向の平坦な両開口端面と、該開口端面に対し直角をなすセル軸方向に沿った平坦な両端面と、を備えたハニカムコアについて、一方の該開口端面側を所定形状に削り加工する方法に関する。そしてこの加工方法では、まず、該ハニカムコアの他方の該開口端面に、より広い大きさの底板を固定的に取付けると共に、所定形状のガイドが形成された対をなすガイド治具を、それぞれ、該底板の両サイドから固定的に立設して、該ハニカムコアのセル軸方向に沿った両端面に沿って配設する。それからトレーサーを、両該ガイド治具のガイドにて案内せしめつつ移動させることにより、該トレーサーに従動すると共に回転されるルーター,サンダー,フライス等の刃物にて、セル軸方向から、該ハニカムコアの一方の該開口端面側を所定形状に削り加工する。なお事後、加工された該ハニカムコアから、該底板,ガイド治具,トレーサー,刃物等が除去される。
【0008】
このように本発明の請求項1では、まず、ハニカムコアの他方の開口端面に当板を固定的に取付けると共に、ハニカムコアのセル軸方向に沿った端面にガイドプレートを固定的に取付ける。それから、ガイドプレートのガイドにて案内しつつ、切削刃にて、ハニカムコアの一方の開口端面側を所定形状に削り加工する。請求項2では、まず、ハニカムコアの他方の開口端面に底板を固定的に取付けると共に、対をなすガイド治具を底板の両サイドから立設固定して、ハニカムコアのセル軸方向に沿った両端面に沿って配設する。それからトレーサーを、両ガイド治具のガイドにて案内しつつ移動させることにより、従動して回転する刃物にて、ハニカムコアの一方の開口端面側を所定形状に削り加工する。
【0009】
このように、これらの加工方法によると、当板とガイドプレートを固定的に取付けてから、切削刃にて削り加工したり、底板やガイド治具を固定的に取付け,立設してから、トレーサーを介し刃物にて削り加工するようにしたことにより、第1に、簡単容易に極めて短時間・短期間のうちに、ハニカムコアを削り加工可能となる。第2に、効率的で手間や作業が比較的少なく、簡単容易に低価格でハニカムコアを削り加工可能となる。
【0010】
【発明の実施の形態】
以下本発明を、図面に示すその発明の実施の形態に基づいて、詳細に説明する。図1,図2,図3は、本発明の実施の形態の1例の説明に供し、図4は、本発明の実施の形態の他の例の説明に供する。
【0011】
そして図1の(1)図は、準備段階を示す斜視図、(2)図は、当板やガイドプレートを取付けた状態を示す斜視図である。図2の(1)図は、切削刃にて削り加工する状態を示す斜視図、(2)図は、加工されたハニカムコアを示す斜視図、(3)図は、加工されたハニカムコアの他の例を示す斜視図である。図3の(1)図は、当板の他の例を示す側面図、(2)図は同斜視図、(3)図は、これと共にガイドプレートの他の例を示す斜視図である。図4の(1)図は、底板やガイド治具を取付け,立設した状態を示す斜視図、(2)図は、刃物にて削り加工する状態を示す正面図である。
【0012】
ハニカムコア1は、中空柱状の多数のセル2の平面的集合体よりなり、全体形状が四角柱体状をなし、セル軸方向Aの平坦な両開口端面3と、この開口端面3に対し直角をなすセル軸方向Aに沿った平坦な両端面4と、を備えてなる。そして、このハニカムコア1の加工方法は、その一方の開口端面3側を、曲面B(図2の(2)図や(3)図参照)等の所定形状に削り加工する方法に関する。
【0013】
まず、これらについて詳述する。ハニカムコア1は、セル壁5にて各々独立空間に区画された、中空柱状の各セル2の平面的集合体よりなる。セル壁5そしてセル2の断面形状は、図示の正六角形状のものが代表的であるが、これによらず、略扁平六角形状,略台形状,略三角形状,略四角形状,その他各種形状のものも可能である。セル壁5そしてハニカムコア1の母材としては、アルミニウム箔その他の金属箔、アラミド紙その他の特殊紙、塩ビシートその他のプラスチックシート、繊維強化プラスチック(FRP)シート、その他パルプを含む有機系や無機系の複合材シート、等々が用いられる。そしてハニカムコア1は、いわゆる展張法、つまり母材に条線状に接合材を塗布して重積,展張するか、又はいわゆるコルゲート法、つまり母材を波板に折曲加工して積層,接合することにより、製造される。ハニカムコア1は、重量比強度に優れ、軽量であると共に高い剛性・強度を備え、又、整流効果,平面精度,保温性,遮音性にも優れ、単位容積当りの表面積が大である、等々の特性が知られている。そしてハニカムコア1は、このような特性を生かし、建築用,構築用,建具用の構造材、各種容器,箱等の構造材,航空機,通信機器等の構造材,一般産業用の構造材,スポーツ用品等の構造材,その他各種の用途に広く使用される。
【0014】
そして、この加工方法において準備されるハニカムコア1は、図1の(1)図等に示したように、全体形状が、扁平なもの等を含む四角柱体状をなす。もってこのハニカムコア1は、セル軸方向Aの平坦で対向する両開口端面3と、セル軸方向Aに沿った平坦で対向する端面4と、を備えてなり、開口端面3とセル軸方向Aに沿った端面4とは、直交する関係にある。図中6はハニカムコア1の側端面であり、この側端面6は、上述した開口端面3やセル軸方向Aに沿った端面4に対し、共に直交する関係にある。この加工方法は、このようなハニカムコア1について、その一方の開口端面3側を削り加工して、例えば3次曲面等の曲面Bその他の所定形状とするものである。
【0015】
まず、図1,図2,図3に示した加工方法について説明する。この加工方法では、まず最初に図1の(1)図,(2)図に示したように、ハニカムコア1の他方の開口端面3に、見合った大きさの当板7を固定的に取付けると共に、当板7の端およびハニカムコア1のセル軸方向Aに沿った端面4に、所定形状のガイド8が形成されたガイドプレート9を、固定的に取付ける。
【0016】
これらについて、更に詳述する。当板7としては、肉厚の厚い剛性板が用いられ、例えばアルミニウム板その他の金属板が用いられるが、図3中に示したように、ハニカムサンドイッチパネルを当板7として用いるようにしてもよい。当板7の大きさは、ハニカムコア1の開口端面3に見合った広さよりなる。そして、このような当板7が、準備されたハニカムコア1の図示例では他方の開口端面3に、一時固定として両面接着テープ,粘着テープ,粘着剤等を用いて固定的に取付けられるが、更に、残った一方の開口端面3にも、このような当板7を固定的に取付けるようにしてもよい。なお、このような当板7の取付けに際しては、固定される当板7が、ハニカムコア1のセル軸方向Aに対し全体的に直交するように留意する。
【0017】
図示例においてハニカムコア1は、このように当板7が固定的に取付けられた開口端面3を左右方向に向け、セル軸方向Aに沿った端面4を上下方向に向けて、セットされる。そして、このようなハニカムコア1のセル軸方向Aに沿った端面4上および当板7の上端に、テンプレートたるガイドプレート9が、両面接着テープ,粘着テープ,粘着剤等を用いて固定的に取付けられる。ガイドプレート9は、ハニカムコア1のセル軸方向Aに沿った端面4に対し、その長手方向の長さに見合った長さと、その短手方向の幅よりは短い幅とを備え、もってこの端面4を部分的に覆う大きさよりなる。そしてガイドプレート9は、その長手方向に沿った右側端が、直線状をなし当板7の端上に固定的に取付けられると共に、長手方向に沿った左側端に、所定形状つまり製品形状に対応したガイド8が形成され、ガイド8は例えば曲線状をなす。ガイドプレート9の材質としては、前述した当板7に準じ例えばアルミニウム板が用いられる。又、このようなガイドプレート9が、図1等に示した例では、ハニカムコア1のセル軸方向Aに沿った端面4の上下双方に固定的に取付けられているが、図3の(1)図,(2)図に示した例のように、ガイドプレート9をその上下いずれか一方のみに固定的に取付けるようにしてもよく、特に、上側のみに固定的に取付けるようにしてもよい。なお図3の(3)図に示した例では、更に、このようなガイドプレート9に対応したガイドプレート10が用いられており、このガイドプレート10は、そのガイド11が上述したガイドプレート9のガイド8に対応した曲線状をなし、ガイド8との間に間隙を存しつつ、ハニカムコア1のセル軸方向Aに沿った端面4上に固定的に取付けられている。
【0018】
次に、この加工方法では、図1の(2)図,図2の(1)図に示したように、切削刃12を用い、ガイドプレート9のガイド8にて案内せしめつつ、セル軸方向Aと直交する方向から、ハニカムコア1の一方の開口端面3側を、所定形状例えば曲面Bに削り加工する。
【0019】
これらについて、更に詳述する。切削刃12としてはバンドソーが代表的に用いられるが、ハニカムコア1の母材として例えばアラミド紙等が用いられた場合には、刃に凹凸カーブが形成されたナイフエッジタイプの刃を用いると、ハニカムコア1の削り加工の仕上がりに優れ、形成される曲面B等にバリ等が発生せず滑らかなセルウオール状態となる。さて、このような切削刃12を用い、セル軸方向Aと直交する上方から、ガイドプレート9のガイド8にて案内せしめつつ、ハニカムコア1の一方の開口端面3側を該開口端面3とは間隔を存しながら、連続的に削り加工して行く(なお図3の(3)図に示した例において、切削刃12は、ガイドプレート9のガイド8とガイドプレート10のガイド11間にて案内されつつ、削り加工を行う)。もって図2の(2)図に示したように、ハニカムコア1が、例えばわん曲した凹凸状の曲面B等の所定形状に削り加工される。又、例えば扁平な四角柱体状のハニカムコア1が対象とされた場合には、図2の(3)図に示したような曲面Bが形成される。なお事後、このように削り加工されたハニカムコア1から、当板7,ガイドプレート9や10等が除去される。図1,図2,図3に示したハニカムコア1の加工方法は、このようになっている。
【0020】
次に、図4に示したハニカムコア1の加工方法について説明する。この加工方法では、図4の(1)図に示したように、まず最初に、ハニカムコア1の他方の開口端面3に、より広い大きさの底板13を固定的に取付けると共に、対をなす所定形状のガイド14が形成されたガイド治具15を、それぞれ、底板13の両サイドから固定的に立設しつつ、ハニカムコア1のセル軸方向Aに沿った両端面4に沿って配設する。
【0021】
これらについて、更に詳述する。底板13としては、アルミニウム板その他の剛性に富んだ金属板等が用いられ、底板13の大きさは、ハニカムコア1の開口端面3に対し、その長手方向の長さに見合った長さと、その短手方向の幅よりは両側に広い幅とを備え、もって、ハニカムコア1の開口端面3より広い大きさよりなる。そして、この発明の実施の形態において例えば繊維強化プラスチックを母材としたハニカムコア1は、開口端面3を上下方向に向け、セル軸方向Aに沿った端面4を左右方向に向けてセットされる。そして、一方の開口端面3を上方に向け他方の開口端面3を下方に向けると共に、この下方に向けられた他方の開口端面3が、底板13の中央部上に、両面接着テープ,粘着テープ,粘着剤等を用いて固定的に取付けられる。なお、ハニカムコア1の下方に向けられた他方の開口端面3に、半硬化状態で粘性を帯びたプリプレグ材よりなるピールプライ板を貼り付けると共に、底板13を吸い付け固定用に通気可能なバキューム構造とし、もって、バキューム装置(図示せず)にて吸気することにより、バキューム構造の底板13に、ハニカムコア1のピールプライ板付の他方の開口端面3を、固定的に取付けるようにすることも考えられる。
【0022】
ガイド治具15は、例えばアルミニウム等前述したガイドプレート9に準じた材質よりなる。そしてガイド治具15は、左右1対の肉厚の厚い長板状をなし、ハニカムコア1のセル軸方向Aに沿った端面4に対し、その長手方向の長さに見合った長さと、その短手方向の高さよりは低い高さとを備え、もってその端面4を部分的に覆う大きさよりなる。そして、この両ガイド治具15は、ハニカムコア1のセル軸方向Aに沿った端面4を挟むように両側から当接されると共に、その長手方向に沿った下端部が直線状をなし、底板13の両サイドに例えばねじ止めにより固定され、立設される。両ガイド治具15の長手方向に沿った上端部には、凹状をなすガイド14が形成されており、このガイド14は、長手方向に沿い例えば曲線状等の製品形状に対応した所定形状をなし、図示例では高さが徐々に変化する高低のわん曲状をなしている。
【0023】
次に、この加工方法では、図4の(2)図に示したように、このような左右の両ガイド治具15のガイド14上、つまりその凹状をなすガイド14内に、トレーサー16の下部17が摺動可能に載せられる。トレーサー16は、平板状をなすと共に脚状に両下部17が垂設され、更に左右両端部に、それぞれ縦にシャフトSが上下動可能に貫挿されており、シャフトSの下端はスライド板18に固定され、スライド板18は、前述した底板13の両サイド上をスライド移動可能となっている。19はスプリングであり、このスプリング19はシャフトSに巻回されつつ、トレーサー16の左右両端部とスライド板18との間に介装され、もってトレーサー16を上方に向け付勢している。
【0024】
そして、この加工方法では、図4の(2)図に示したように、トレーサー16を、両ガイド治具15のガイド14にて案内せしめつつ移動させることにより、トレーサー16に従動すると共に回転されるルーター,サンダー,フライス等の刃物20にて、セル軸方向Aから、ハニカムコア1の一方の開口端面3側を所定形状に削り加工する。
【0025】
これらについて、更に詳述する。トレーサー16の中央部には、刃物20が取付けられており、刃物20としては、切削爪を備えたハンドルーター,円錐刃の下面に砂粒を付着せしめたサンダー,切削フライス等が用いられる。刃物20は、一体的に上下動可能にトレーサー16に取付けられると共に、回転可能となっている。そして本体部21から、前述したスプリング19の上方への付勢力に抗した下方への押圧力が、このようなトレーサー16と刃物20に付与されると共に、本体部21から、回転力が刃物20に伝達される。もって、このような刃物20の下面が、底板13上に固定的に取付けられたハニカムコア1の上方向に向けられた一方の開口端面3上に、対応位置決めされる。
【0026】
そして、本体部21にてトレーサー16や刃物20に下方への押圧力を加えつつ、トレーサー16を、両ガイド治具15のガイド14上に当てがい、ガイド14の曲線・高さ変化に沿って案内させつつ移動させて行く。これにより、トレーサー16に従動して上下動すると共に、本体部21にて回転される刃物20にて、ハニカムコア1の一方の開口端面3側が、連続的に曲面B(前述した図2の(2)図,(3)図を参照)等の所定形状に削り加工されて行く。つまり、ガイド治具15のガイド14の高さ変化をトレーサー16が辿り、このようなトレーサー16に従動して刃物20が、ならって高さ変化して送られつつ回転することにより、ハニカムコア1の一方の開口端面3側が、上方から削り加工され、もって、例えばわん曲した凹凸状の曲面B等を備えたハニカムコア1が得られる。なお事後、このように削り加工されたハニカムコア1から、底板13,両ガイド治具15,トレーサー16,刃物20,本体部21等が除去される。図4に示したハニカムコア1の加工方法は、このようになっている。
【0027】
本発明は、以上説明したように構成されている。そこで以下のようになる。図1,図2,図3に示したハニカムコア1の加工方法では、まず、ハニカムコア1の左右いずれかの他方の開口端面3に、当板7を固定的に取付けると共に、当板7の上端およびハニカムコア1のセル軸方向Aに沿った端面4上に、ガイドプレート9を固定的に取付ける。それから、ガイドプレート9のガイド8にて案内しつつ、切削刃12にて上方からハニカムコア1の一方の開口端面3側を、曲面B等の所定形状に削り加工する。又、図4に示したハニカムコア1の加工方法では、まず、ハニカムコア1の他方の開口端面3に底板13を固定的に取付けると共に、対をなすガイド治具15を、底板13の両サイドから立設固定しつつ、ハニカムコア1のセル軸方向Aに沿った左右の両端面4に沿って配設する。それからトレーサー16を、両ガイド治具15のガイド14にて案内しつつ移動させることにより、これに従動しつつ回転する刃物20にて、ハニカムコア1の一方の開口端面3側を曲面B等の所定形状に削り加工して行く。さてそこで、このようなハニカムコア1の加工方法によると、次の第1,第2のようになる。
【0028】
第1に、この加工方法によると、図1,図2,図3に示したように、所定の当板7とガイドプレート9を固定的に取付けてから、切削刃12にて削り加工したり、図4に示したように、所定の底板13やガイド治具15を固定的に取付け,立設してから、トレーサー16を介し刃物20にて削り加工するようにしたことにより、極めて短時間・短期間のうちに、ハニカムコア1を曲面B等の所定形状に削り加工可能となる。すなわちこの加工方法によると、前述したNC加工によるこの種従来例のように、予めプログラミング時間を要することがなく、又、ダミーを使ったテスト加工を先立って必須的に要することもない。更に、特にいわゆる展張法にて製造されたハニカムコア1は、構造上剥がれやすい上に、柔性を帯びているので圧縮されやすく位置決め保持しにくいが、当板7とガイドプレート9の組み合わせや底板13とガイド治具15の組み合わせにより、簡単容易かつ短時間のうちに、このようなハニカムコア1を、剥がれることなく確実に保護しつつ位置決め保持できる。もって、極めて短時間・短期間のうちに、ハニカムコア1を曲面B等の所定形状に削り加工可能となる。
【0029】
第2に、この加工方法によると同様に、図1,図2,図3に示したように、所定の当板7とガイドプレート9を固定的取付けてから、切削刃12にて削り加工したり、図4に示したように、所定の底板13やガイド治具15を固定的に取付け,立設してから、トレーサー16を介し刃物20にて削り加工するようにしたことにより、低価格で、ハニカムコア1を曲面B等の所定形状に削り加工可能となる。すなわちこの加工方法によると、前述したNC加工によるこの種従来例のように、予めプログラミング作業を要することがなく、又、テスト加工作業も必須的ではなく、ダミーのハニカムコア1を必ず必要とすることもない。更に、特にいわゆる展張法で製造されたハニカムコア1は構造上剥がれやすい上に、柔性を帯びているので圧縮されやすく位置決め保持しにくいが、当板7とガイドプレート9の組み合わせや底板13とガイド治具15の組み合わせにより、簡単容易かつスムーズに、このようなハニカムコア1を、剥がれることなく確実に保持しつつ位置決め保持できる。もって、効率的で手間や作業が比較的少なく、簡単容易に低価格で、ハニカムコア1を曲面B等の所定形状に削り加工可能となる。
【0030】
【発明の効果】
本発明に係るハニカムコアの加工方法は、以上説明したように、請求項1では、所定の当板とガイドプレートを固定的に取付けてから、切削刃にて削り加工するようにしたことにより、請求項2では、所定の底板やガイド治具を固定的に取付け,立設してから、トレーサーを介し刃物にて削り加工するようにしたことにより、次の効果を発揮する。
【0031】
第1に、時間面・期間面に優れつつ、ハニカムコアを曲面等の所定形状に、削り加工することができる。すなわち、この加工方法によると、前述したNC加工によるこの種従来例のように、予めプログラミング時間を要することがなく、又、ダミーを使ったテスト加工を先立って必須的に要することもなく、更に、構造上剥がれやすい上に柔性を帯び位置決め保持しにくいハニカムコアにも、簡単容易かつ短時間のうちにスムーズに対応できる。もってこの加工方法は、この種従来例に比し、ハニカムコアの開口端面を曲面等の所定形状に、極めて短時間・短期間のうちに削り加工でき、時間面・期間面に優れている。
【0032】
第2に、これと共にコスト面にも優れつつ、ハニカムコアを曲面等の所定形状に、削り加工することができる。すなわち、この加工方法によると、前述したNC加工によるこの種従来例のように、予めプログラミング作業を要することがなく、又、テスト加工作業も必須的ではなく、ダミーのハニカムコアを必ず必要とすることもなく、更に、構造上剥がれやすい上に柔性を帯び位置決め保持しにくいハニカムコアにも、簡単容易かつスムーズに対応できる。もってこの加工方法は、この種従来例に比し、ハニカムコアの開口端面を曲面等の所定形状に、効率的に低価格で削り加工でき、コスト面にも優れている。このように、この種従来例に存した課題がすべて解決される等、本発明の発揮する効果は、顕著にして大なるものがある。

[0002]
[Prior art]
In the case where the opening end face of a honeycomb core formed of a planar aggregate of hollow columnar cells is cut into a predetermined shape such as a cubic curved surface, NC processing has generally been employed conventionally. That is, numerical data for selecting and indicating the position, feed amount, cutting amount, angle, direction, speed, etc. of the cutting tool with respect to the honeycomb core is programmed in advance, and based on such programming information, an arithmetic mechanism and The operation of the cutting tool is automatically controlled via a servo mechanism, and the opening end face of the honeycomb core is cut into a predetermined shape.

Test processing using a dummy prior to processing was necessary for demonstration, and this also required time. Furthermore, honeycomb cores manufactured by the so-called stretching method are particularly easy to peel off due to their structure, and because they have flexibility, they are easily compressed and are difficult to position and hold, so actual shaving can be performed only by about 2 mm each. , Its feed speed was also set to be slow. Due to these factors, the machining of the honeycomb core into a predetermined shape has traditionally required a very long time from programming to the completion of the machining. Was pointed out.

[0014]
The honeycomb core 1 prepared in this processing method has a square pillar shape including a flat shape as shown in FIG. 1 (1) and the like. Thus, the honeycomb core 1 includes flat and opposing open end faces 3 in the cell axis direction A, and flat and opposing end faces 4 along the cell axis direction A. Is perpendicular to the end surface 4 along. In the figure, reference numeral 6 denotes a side end surface of the honeycomb core 1, and the side end surface 6 is orthogonal to the above-described open end surface 3 and the end surface 4 along the cell axis direction A. In this processing method, one of the honeycomb cores 1 is shaved on one of the open end surfaces 3 to form a curved surface B such as a cubic curved surface or other predetermined shape.
[0015]
First, the processing method shown in FIGS. 1, 2, and 3 will be described. In this working method, first, as shown in FIGS. 1 (1) and (2) of FIG. 1, a corresponding plate 7 having a suitable size is fixedly attached to the other open end face 3 of the honeycomb core 1. At the same time, a guide plate 9 on which a guide 8 having a predetermined shape is formed is fixedly attached to the end of the contact plate 7 and the end face 4 of the honeycomb core 1 along the cell axis direction A.
[0016]
These will be described in more detail. As the contact plate 7, a thick rigid plate is used, for example, an aluminum plate or another metal plate is used. However, as shown in FIG. 3, a honeycomb sandwich panel may be used as the contact plate 7. Good. The size of the contact plate 7 has a size corresponding to the opening end face 3 of the honeycomb core 1. In the illustrated example of the prepared honeycomb core 1, such a contact plate 7 is fixedly attached to the other open end face 3 using a double-sided adhesive tape, an adhesive tape, an adhesive, or the like as a temporary fixing. Further, such a contact plate 7 may be fixedly attached to one of the remaining opening end surfaces 3. In attaching such a contact plate 7, care should be taken that the fixed contact plate 7 is generally perpendicular to the cell axis direction A of the honeycomb core 1.
[0017]
In the illustrated example, the honeycomb core 1 is set with the opening end face 3 to which the abutment plate 7 is fixedly attached as described above facing in the left-right direction, and the end face 4 along the cell axis direction A facing in the up-down direction. A guide plate 9 serving as a template is fixed on the end face 4 of the honeycomb core 1 along the cell axis direction A and on the upper end of the plate 7 by using a double-sided adhesive tape, an adhesive tape, an adhesive or the like. Mounted. The guide plate 9 has a length corresponding to the length in the longitudinal direction and a width shorter than the width in the short direction with respect to the end face 4 of the honeycomb core 1 along the cell axis direction A. 4 so as to partially cover it. The guide plate 9 has a right end along the longitudinal direction which is linear and fixedly mounted on the end of the abutment plate 7 and a left end along the longitudinal direction which corresponds to a predetermined shape, that is, a product shape. The guide 8 is formed, and the guide 8 has, for example, a curved shape. As a material of the guide plate 9, for example, an aluminum plate is used in accordance with the above-described contact plate 7. In the example shown in FIG. 1 and the like, such a guide plate 9 is fixedly attached to both the upper and lower sides of the end face 4 of the honeycomb core 1 along the cell axis direction A. As in the example shown in FIGS. 2 and 3, the guide plate 9 may be fixedly attached to only one of the upper and lower sides, and in particular, may be fixedly attached only to the upper side. . In the example shown in FIG. 3 (3), a guide plate 10 corresponding to such a guide plate 9 is further used. The honeycomb core 1 has a curved shape corresponding to the guide 8, and is fixedly mounted on the end face 4 along the cell axis direction A of the honeycomb core 1 with a gap between the guide 8.
[0018]
Next, in this processing method, as shown in FIG. 1 (2) and FIG. 2 (1), while being guided by the guide 8 of the guide plate 9 using the cutting blade 12, in the cell axial direction. One opening end face 3 of the honeycomb core 1 is cut into a predetermined shape, for example, a curved surface B from a direction orthogonal to A.
[0019]
These will be described in more detail. A band saw is typically used as the cutting blade 12, but when, for example, aramid paper or the like is used as the base material of the honeycomb core 1, if a blade of a knife edge type having a concave and convex curve formed on the blade, The honeycomb core 1 is excellent in the finish of the shaving process, and has a smooth cell wall state without burrs or the like on the formed curved surface B or the like. Now, using such a cutting blade 12, one opening end face 3 side of the honeycomb core 1 is made to correspond to the opening end face 3 while being guided by the guide 8 of the guide plate 9 from above, which is orthogonal to the cell axis direction A. The cutting is continuously performed while leaving an interval. (In the example shown in FIG. 3C, the cutting blade 12 is disposed between the guide 8 of the guide plate 9 and the guide 11 of the guide plate 10. Shaving is performed while being guided). Thus, as shown in FIG. 2B, the honeycomb core 1 is cut into a predetermined shape such as a curved uneven surface B. Further, for example, when the honeycomb core 1 is a flat quadrangular prism, a curved surface B as shown in FIG. 2C is formed. After the fact, the contact plate 7, the guide plates 9 and 10 and the like are removed from the honeycomb core 1 thus cut. The method for processing the honeycomb core 1 shown in FIGS. 1, 2, and 3 is as described above.
[0020]
Next, a method for processing the honeycomb core 1 shown in FIG. 4 will be described. In this processing method, as shown in FIG. 4A, first, a bottom plate 13 having a larger size is fixedly attached to the other open end face 3 of the honeycomb core 1 and forms a pair. Guide jigs 15 on which guides 14 having a predetermined shape are formed are arranged along both end faces 4 along the cell axis direction A of the honeycomb core 1 while fixedly standing from both sides of the bottom plate 13. I do.
[0021]
These will be described in more detail. As the bottom plate 13, an aluminum plate or another metal plate having high rigidity or the like is used. The size of the bottom plate 13 is a length corresponding to the longitudinal length of the opening end face 3 of the honeycomb core 1. The honeycomb core 1 has a width wider on both sides than the width in the lateral direction, and thus has a size wider than the open end face 3 of the honeycomb core 1. In the embodiment of the present invention, for example, the honeycomb core 1 made of fiber reinforced plastic as a base material is set with the opening end face 3 facing up and down and the end face 4 along the cell axis direction A facing left and right. . Then, one opening end face 3 is directed upward and the other opening end face 3 is directed downward, and the other opening end face 3 directed downward is provided on a central portion of the bottom plate 13 with a double-sided adhesive tape, an adhesive tape, It is fixedly attached using an adhesive or the like. In addition, a peel ply plate made of a prepreg material which is viscous in a semi-cured state is attached to the other open end face 3 which is directed downward of the honeycomb core 1, and a vacuum structure capable of sucking the bottom plate 13 and allowing ventilation for fixing. Then, it is also conceivable that the other opening end face 3 of the honeycomb core 1 with the peel ply plate is fixedly attached to the bottom plate 13 of the vacuum structure by suctioning the air with a vacuum device (not shown). .
[0022]
The guide jig 15 is made of a material similar to the above-described guide plate 9 such as aluminum. The guide jig 15 has a pair of left and right thick, long plates, and has a length corresponding to the length in the longitudinal direction with respect to the end face 4 of the honeycomb core 1 along the cell axis direction A. It has a height that is lower than the height in the lateral direction, and has a size that partially covers the end face 4. The guide jigs 15 are abutted from both sides so as to sandwich the end face 4 of the honeycomb core 1 along the cell axis direction A, and the lower end of the guide jig 15 along the longitudinal direction has a linear shape. 13 is fixed and screwed up, for example, by screws. A guide 14 having a concave shape is formed at the upper end of the guide jigs 15 along the longitudinal direction, and the guide 14 has a predetermined shape corresponding to a product shape such as a curved shape along the longitudinal direction. In the illustrated example, the height is gradually changed.
[0023]
Next, in this processing method, as shown in FIG. 4B, the lower part of the tracer 16 is placed on the guides 14 of the left and right guide jigs 15, that is, in the concave guides 14. 17 is slidably mounted. The tracer 16 is formed in a flat plate shape, and both lower portions 17 are vertically suspended in a leg shape. Further, a shaft S is vertically inserted through left and right ends so as to be vertically movable, and a lower end of the shaft S is provided with a slide plate 18. The slide plate 18 is slidable on both sides of the bottom plate 13 described above. Reference numeral 19 denotes a spring. The spring 19 is interposed between the right and left ends of the tracer 16 and the slide plate 18 while being wound around the shaft S, and urges the tracer 16 upward.
[0024]
Then, in this processing method, as shown in FIG. 4B, the tracer 16 is moved while being guided by the guides 14 of both guide jigs 15 so that the tracer 16 is driven and rotated. Using a cutting tool 20 such as a router, sander, milling machine, or the like, one opening end face 3 of the honeycomb core 1 is cut into a predetermined shape from the cell axis direction A.
[0025]
These will be described in more detail. A cutting tool 20 is attached to the center of the tracer 16. As the cutting tool 20, a hand router having a cutting claw, a sander in which sand is adhered to the lower surface of a conical blade, a cutting milling cutter, or the like is used. The blade 20 is attached to the tracer 16 so as to be integrally movable up and down, and is rotatable. A downward pressing force against the above-described biasing force of the spring 19 is applied to the tracer 16 and the blade 20 from the main body 21, and the rotational force is applied from the main body 21 to the blade 20. Is transmitted to. Thus, the lower surface of such a cutting tool 20 is correspondingly positioned on one opening end face 3 of the honeycomb core 1 fixedly mounted on the bottom plate 13 and facing upward.
[0026]
Then, the tracer 16 is applied to the guides 14 of both the guide jigs 15 while applying a downward pressing force to the tracer 16 and the blade 20 by the main body portion 21, and along the curve / height change of the guides 14. Move while guiding. As a result, the one end face 3 of the honeycomb core 1 is continuously curved B (FIG. 2) Refer to FIG. 3 and FIG. 3)). In other words, the tracer 16 follows the change in height of the guide 14 of the guide jig 15, and the blade 20 follows the tracer 16, and rotates while being sent while changing the height, thereby making the honeycomb core 1. Is cut from the upper side to obtain the honeycomb core 1 having, for example, a curved surface B having a concave and convex shape. After the fact, the bottom plate 13, the two guide jigs 15, the tracer 16, the cutting tool 20, the main body 21 and the like are removed from the honeycomb core 1 thus cut. The method for processing the honeycomb core 1 shown in FIG. 4 is as described above.
[0027]
