【発明の属する技術分野】
本発明は、リングヒータを用いた分離開放可能な反射型加熱装置に関し、より詳しくは、棒状物の周囲を均一且つ高速で加熱することができ、しかも装置全体をコンパクトに構成することができ、棒状物の配置及び交換を容易かつ速やかに行うことができる、リングヒータを用いた分離開放可能な反射型加熱装置に関する。
【0002】
【従来の技術】
金属線材等の試料を加熱するための装置として、赤外線照射型の加熱装置が提案されており、その例として、内周面が回転楕円鏡面である3個以上の反射体をリング状に並べ、各反射体の一方の焦点にそれぞれ点光源を配置し、各反射体の他方の焦点を、試料が位置する共通の一致焦点とした、赤外線照射型の加熱装置がある(特許文献1参照)。

【0004】
【発明が解決しようとする課題】
しかしながら、上記した赤外線照射型の加熱装置は、点光源を用いるものであるため、単位時間あたりの熱照射量が少なく、試料を加熱するのに時間がかかるという問題があった。点光源の数を増やせば熱照射量を増やすことができるが、この場合、鏡の数も増えるから装置全体が大型化してしまい、移動や持ち運びが難しくなるという問題があった。
また、試料の径が大きい場合、その周面を、周方向に連続ではなく不連続の点で加熱することになるから、試料を周方向に沿って満遍なく加熱することができず、加熱にムラができる可能性があった。
また、この加熱装置は、隣り合う反射体を連続一体的に形成したものであるため、複数の反射体に囲まれた中央孔に棒状の試料を配置する場合、その中央孔の軸長方向に沿って試料を移動させ、その孔に対する抜き差しをしなければならない。試料が長いものであれば、その抜き差し作業には非常に手間がかかった。
【0005】
本発明は、このような実情に鑑みてなされたもので、棒状物の周囲を均一且つ高速で加熱することができ、しかも装置全体をコンパクトに構成することができ、棒状物の配置及び交換を容易かつ速やかに行うことができる、リングヒータを用いた分離開放可能な反射型加熱装置の提供を目的とする。

【発明の実施の形態】
本発明に係るリングヒータを用いた分離開放可能な反射型加熱装置の実施形態について、図面を参照しつつ説明する。
図1は、本発明に係る反射型加熱装置の内部を示す図であり、リングヒータ全周を含む仮想平面を境に2つに分割した凹楕円鏡面体の一方を、リングヒータと共に示す平面図である。図2は、本発明に係る反射型加熱装置の断面図である。尚、図1に示す例では冷却媒体導入部を左側に位置させているが、図2に示す例では右側に位置させている。図3は、本発明に係る反射型加熱装置の平面図である。図4は、本発明におけるリングヒータを示す平面図である。図5は、本発明に係る反射型加熱装置において、赤外光が進む様子を示す断面図である。
【0010】
まず、反射体として凹楕円鏡面体(3)を用いる場合(第1実施形態)について説明する。
反射型加熱装置(1)は、リングヒータ(2)と、リング状の凹楕円鏡面体(3)とからなり、リングヒータ(2)から出た赤外光を凹楕円鏡面(4)で反射し、その反射光を棒状体(被加熱物)(5)に照射するものである。
リングヒータ(2)は、図1及び図4に示される如く2つの半円状ヒータ(20),(20)を円形状に組み合わせることにより構成され、凹楕円鏡面体(3)は、図1及び図3に示される如く2つの半円状鏡面体(21),(21)を円形状に組み合わせることにより構成される。2つの半円状ヒータ(20),(20)、及び、2つの半円状鏡面体(21),(21)は共に、分離開放手段(22)(図10,11,12参照)によって2つの半円同士が相互に離隔/接近可能とされ、離隔時に半円同士の間に形成される分離開放空間(23)(図11参照)を通じて棒状体(5)を出し入れ可能となっている。
【0011】
尚、棒状体(5)の形態は特に限定されるものではなく、中空の棒状体すなわち管状体、或いは、中実の棒状体のいずれであってもよい。
また、棒状体(5)を加熱する目的は特に限定されるものではなく、例えば、金属管状体への棒の焼きばめ、金属棒状体の焼き入れ等の金属熱処理、或いは、金属棒状体の曲げ加工等の金属加工を目的とすることができるが、図示例では、マシニングセンタの切削工具(15)(図6参照)を、工具保持筒(5)の保持孔に焼きばめする際に、その工具保持筒(5)を加熱するのに用いている。
以下、これら構成要素について詳説する。
【0012】
半円状ヒータ(20)は、半円状の赤外線発光フィラメント(以下、フィラメントと称する)(6)(図4参照)と、このフィラメント(6)を収容保持する半円状の透明収容管(7)とからなるものである。フィラメント(6)は、例えばタングステン線のコイルを半円状に湾曲させたものであり、透明収容管(7)は、例えば透明な石英管を半円状に湾曲させたものである。フィラメント(6)は、複数のサポータ(図示せず)を介して透明収容管(7)内に固定されている。透明収容管(7)の一端部と他端部には、それぞれフィラメントの陽極と陰極が設けられており、これらの極は、電線を介して電源に接続されている。
一方の半円状ヒータ(20)は一方の半円状鏡面体(21)内に固定され、他方の半円状ヒータ(20)は他方の半円状鏡面体(21)内に固定される。
【0013】
リング状の凹楕円鏡面体(3)は、リングヒータ(2)に沿って該リングヒータ(2)を覆うように配置されるもので、内周面の周方向略全体に渡って凹楕円鏡面(4)が形成され、その一方の焦点である外側焦点(8)(図2,5参照)に発光フィラメント(6)が位置され、他方の焦点である内側焦点(9)(図5参照)に加熱すべき棒状体(5)を配置可能としたものである。内側焦点(9)は、凹楕円鏡面(4)で囲まれた空間の中央部に位置し、外側焦点(8)は、その空間の凹楕円鏡面(4)付近に位置し、同空間内においてこれらは相対的に内側と外側に位置する。
内側焦点(9)は、リング状の凹楕円鏡面(4)全周において、図5に示される如く、凹楕円鏡面体(3)の中心線(18)上で一点に集中してもよいが、図8に示される如く、リング状の凹楕円鏡面(4)全周についての各焦点(9)の集合が、凹楕円鏡面体(3)の中心線(18)近傍で該中心線(18)を中心とする円を形成してもよい。尚、図8に示される各内側焦点(9)は、凹楕円鏡面体(3)の中心線(18)を越えた位置にあるが、中心線(18)の手前に位置してもよい。
凹楕円鏡面(4)には、複数のヒータ支持板(10)が放射状に突設されており、これらヒータ支持板(10)によって、半円状ヒータ(20)は、半円状凹楕円鏡面体(21)内の所定の位置に固定される。
【0014】
外側焦点(8)は、凹楕円鏡面(4)全体についての各焦点(8)の集合が円(以下、焦点円と称する)を形成し、発光フィラメント(6)は、その全体が焦点円に重合一致するように配置される。
発光フィラメント(6)から出た赤外光は凹楕円鏡面(4)で反射され、その反射光の全てが内側焦点(9)に向かい、該内側焦点(9)上もしくはその近傍にある棒状体(5)を、焦点(9)近傍において周方向全体に渡り均一に加熱する。
棒状体(5)は、任意の保持装置(図11参照)によって、凹楕円鏡面体(3)の中央孔(11)に挿通配置することができる。
【0015】
図10及び図11に示される如く、2つの半円状鏡面体(21)はそれぞれ、2本の揺動アーム(24)の先端側に個別に取付けられる。揺動アーム(24)の先端部一側面には、半円状の鏡面体収容部(25)が形成されている。一方の揺動アーム(24)は、鏡面体収容部(25)において一方の半円状鏡面体(21)を収容保持する。他方の揺動アーム(24)は、鏡面体収容部(25)において他方の半円状鏡面体(21)を収容保持する。
2本の揺動アーム(24)は、その先端部同士が同一平面内で互いに接近、離隔するように揺動することができ、先端部同士が最も接近したときに鏡面体収容部(25)の端部(半円の両端部に相当する)同士が接触する。逆に、先端部同士が離隔するにつれ、鏡面体収容部(25)の端部同士が離隔し、これにより、収容された半円状鏡面体(21),(21)は互いに離隔し、その離隔により形成された分離開放空間(23)を通じて、棒状体(5)を出し入れすることができる。
本発明における分離開放手段(22)は、例えば、これら2本の揺動アーム(24)から構成することができるが、特に限定はされない。
【0016】
尚、本発明においては、半円状鏡面体(21)は、図1及び図2に示される如く、下流端が該鏡面体(3)の内周部で開口する冷却媒体搬送路(13)を有し、この搬送路(13)の上流端は冷却媒体供給装置(図示せず)に接続され、前記開口部(14)から、棒状体(5)に向けて冷却媒体を吹き付け可能とされていることが好ましい。冷却媒体の種類は特に限定されるものではないが、例えば、水、空気を挙げることができる。
このような構成とすれば、加熱された棒状体(5)を急速冷却することができ、棒状体(5)の焼き入れ処理を良好に行い、また、焼きばめ後の棒状体(5)を速やかに冷却してはめあいを速やかに完了し、作業効率を高めることができる。
揺動アーム(24)には、搬送路(13)の上流端と冷却媒体供給装置(図示せず)を繋ぐ流路(図示せず)が形成されている。
【0017】
また、本発明においては、半円状鏡面体(21)は、リングヒータ(2)の全周を含む仮想平面(12)を境に、2つに分割可能とされていることが好ましい。
このような構成とすれば、リングヒータ(2)の交換時に半円状鏡面体(21)を分割し、リングヒータ(2)の取り出し、交換を容易かつ速やかに行うことができる。
【0018】
次に、この反射型加熱装置(1)の使用方法について説明する。
ここでは、マシニングセンタの切削工具(15)(図6参照)を工具保持筒(棒状体)(5)に焼きばめするための、工具保持筒(5)の加熱処理を例にとる。
まず、図11に示す如く、2本の揺動アーム(24),(24)の先端部同士を開き、2つの半円状鏡面体(21),(21)同士の間に分離開放空間(23)を形成する。この分離開放空間(23)を通じて棒状体(5)を鏡面体(3)の中央孔(11)内に入れ、工具保持筒(5)の一端部を把持装置等を用いて固定し、工具保持筒(5)を、凹楕円鏡面体(3)の中央孔(11)に配置する。このとき、凹楕円鏡面体(3)の内側焦点(9)に、工具保持筒(5)の加熱すべき部分を位置させる。
2本の揺動アーム(24),(24)の先端部同士を閉じ、2つの半円状鏡面体(21),(21)の端部同士を接触させ、リング状の凹楕円鏡面体(3)を構成する。
【0019】
電源をオンにし、リングヒータ(2)の発光を開始すると、図5に二点鎖線で示す如く、その光(赤外光)は、凹楕円鏡面(4)で反射され、反射された光は全て内側焦点(9)に向かう。内側焦点(9)は、凹楕円鏡面体(3)の中心線上にある。反射光は、工具保持筒(5)の加熱すべき部分を全周にわたって均一に加熱する。工具保持筒(5)は、赤外光放射量の大きいリングヒータ(2)によってその全周が加熱されるから高速加熱されるとともに全周が均一に加熱され、その温度は目標の温度まで速やかに上昇する。
【0020】
加熱された工具保持筒(5)の保持孔には、ドリル等の切削工具(15)(図6参照)の一端部が挿入される。所定深さまで切削工具(15)を挿入したら、冷却媒体搬送路(13)を通じてその一端開口部(14)(図7参照)から、空気或いは冷却水を噴出させ、この冷却媒体によって工具保持筒(5)を直接に急速冷却する。冷却媒体の流れは、例えば図7中の矢印の向きとなる。
このように工具保持筒(5)を急速冷却すると、工具保持筒(5)と切削工具(15)の焼きばめが速やかに終了する。
1本目の焼きばめ作業が終了したら、2本目の作業に取り掛かるために、2本の揺動アーム(24),(24)の先端部同士を開き、2つの半円状鏡面体(21),(21)同士の間に分離開放空間(23)を形成する。この分離開放空間(23)を通じて1本目の工具保持筒(5)を鏡面体(3)から取り出し、代わりに2本目の工具保持筒(5)を鏡面体(3)内に入れる。2本の揺動アーム(24),(24)の先端部同士を再び閉じ、2つの半円状鏡面体(21),(21)の端部同士を接触させ、リング状の凹楕円鏡面体(3)を構成する。以下、1本目と同様の手順で加熱処理を行う。
【0021】
この発明によれば、棒状体(5)の周囲を均一且つ高速で加熱することができる。また、発光量の多いリングヒータ(2)から赤外線を放ち、その光をリング状の鏡面(4)で反射するから、高速加熱するにあたりヒータ及び反射鏡をいくつも設ける必要がなく、装置全体をコンパクトに構成することができる。
更に、分離開放空間(23)を通じて棒状体(5)を出し入れし、その抜き差しを容易かつ速やかに行うことができる。棒状体(5)が長く、中央孔(11)の軸長方向に抜き差しし難い場合に特に有効である。
【0022】
次に、本発明の第2実施形態について図9を参照しつつ説明する。
第2実施形態が上記第1実施形態と異なる点は、リング状の凹楕円鏡面体(3)に代えて、リング状の凹放物鏡面体(16)が設けられている点である。
リング状の凹放物鏡面体(16)は、リングヒータ(2)に沿って該リングヒータを覆うように配置されるものであり、内周面の周方向略全体に渡って凹放物鏡面(17)が形成され、その焦点(19)に発光フィラメント(6)が位置される。
リングヒータ(2)から出た赤外光は、凹放物鏡面(17)で反射され、その反射光は、凹放物鏡面体(16)の中央孔(11)の中心線(18)上に配置された棒状体(5)に照射される。
尚、第1実施形態と同様、リングヒータ(2)は、2つの半円状ヒータ(20),(20)を円形状に組み合わせることにより構成され、凹放物鏡面体(16)は、2つの半円状鏡面体(26),(26)を円形状に組み合わせることにより構成される。
【0023】
この実施形態においては、凹放物鏡面(17)で反射された光は、図9に二点鎖線で示す如く、互いに平行な光となり、中央孔(11)の中心線(18)に向かって該中心線(18)に対し直角に進む。従って、棒状体(5)において、凹放物鏡面(17)の中心線(18)方向の長さに相当する部分全体に満遍なく光が当たり、この部分が均等に加熱される。
【0024】
この第2実施形態においても、上記第1実施形態と同様に使用することができる。
また、半円状鏡面体(26)は、一端が該鏡面体(26)の内周部で開口する冷却媒体搬送路(13)を有し、この搬送路(13)の他端は冷却媒体供給装置に接続され、前記開口部(14)から、棒状体(5)に向けて冷却媒体を吹き付け可能とされていることが好ましい。
このような構成とすれば、加熱された棒状体(5)を急速冷却することができ、棒状体(5)の焼き入れ処理を良好に行い、また、焼きばめ後の棒状体(5)を速やかに冷却してはめあいを速やかに完了し、作業効率を高めることができる。
【0025】
また、半円状鏡面体(26)は、リングヒータ(2)の全周を含む仮想平面(12)を境に、2つに分割可能とされていることが好ましい。
このような構成とすれば、リングヒータ(2)の交換時に半円状鏡面体(26)を分割し、リングヒータ(2)の取り出し、交換を容易かつ速やかに行うことができる。
【0026】
【発明の効果】
請求項1、請求項2記載の発明によれば、棒状物の周囲を均一且つ高速で加熱することができる。また、発光量の多いリングヒータから赤外線を放ち、その光をリング状の鏡面で反射するから、高速加熱するにあたりヒータ及び反射鏡をいくつも設ける必要がなく、装置全体をコンパクトに構成することができる。また、分離開放空間を通じて棒状体を出し入れし、その抜き差しを容易かつ速やかに行うことができる。棒状体が長く、鏡面体中央孔からその軸長方向に抜き差しし難い場合に特に有効である。
請求項3記載の発明によれば、加熱された棒状体を急速冷却することができ、棒状体の焼き入れ処理を良好に行い、また、焼きばめ後の棒状体を速やかに冷却してはめあいを速やかに完了し、作業効率を高めることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a reflection-type heating device that can be separated and opened using a ring heater, and more specifically, can uniformly and rapidly heat the periphery of a rod-shaped object, and can further reduce the size of the entire device, The present invention relates to a reflection-type heating device that can easily and promptly arrange and replace a rod-shaped object and that can be separated and opened using a ring heater.
[0002]
[Prior art]
As a device for heating a sample such as a metal wire, an infrared irradiation type heating device has been proposed. As an example, three or more reflectors whose inner peripheral surfaces are spheroidal mirror surfaces are arranged in a ring shape, There is an infrared irradiation type heating device in which a point light source is arranged at one focal point of each reflector, and the other focal point of each reflector is used as a common coincident focal point where a sample is located (see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-9-257374
[Problems to be solved by the invention]
However, since the infrared irradiation type heating device described above uses a point light source, there is a problem that the amount of heat irradiation per unit time is small and it takes time to heat the sample. If the number of point light sources is increased, the amount of heat irradiation can be increased. However, in this case, the number of mirrors also increases, so that the entire apparatus becomes large, and there is a problem that it is difficult to move and carry.
In addition, when the diameter of the sample is large, the peripheral surface is heated at discontinuous points instead of being continuous in the circumferential direction. Therefore, the sample cannot be heated uniformly along the circumferential direction, resulting in uneven heating. Could be possible.
Further, since this heating device is formed by continuously forming adjacent reflectors, when a rod-shaped sample is placed in a central hole surrounded by a plurality of reflectors, the heating device is arranged in the axial direction of the central hole. The sample must be moved along and the holes must be inserted and removed. If the sample is long, it takes a lot of time to remove and insert it.
[0005]
The present invention has been made in view of such circumstances, and can uniformly and rapidly heat the periphery of a rod-shaped object, and can further configure the entire apparatus in a compact size, and can arrange and replace the rod-shaped object. It is an object of the present invention to provide a reflection-type heating device that can be easily and quickly performed and that can be separated and opened using a ring heater.
[0006]
