Abstract
Description
以上のごとく従来の技術では、高性能の羽根部材を合理的に得るには未だ解決すべき問題があった。
本発明に係る流体ポンプ用の羽根部材の第1特徴構成は、回転軸芯を中心に形成された筒状部と、前記筒状部のうち前記回転軸芯に沿った一方の端部から前記回転軸芯の径方向外方に突出し、周方向に沿って複数設けられる基部と、前記基部の夫々から前記回転軸芯に沿って一方向に曲げられた屈曲部と、隣り合う前記基部の根元部どうしの境界位置に設けたホール部とを備え、前記ホール部から前記屈曲部の先端に至る立上り縁部と、前記ホール部から前記基部の先端に至る張出し縁部とを、共通の切断部位によって形成した点にある。
本構成の羽根部材では、屈曲部に形成される立上り縁部と、基部に形成される張出し縁部とが、共通の切断部位によって形成されている。これは、本構成においては、ワークの切断と曲げ加工とが同時に行なわれることに基づく。つまり、径方向外方に突出する基部に設けられた張出し縁部と、基部から回転軸芯に沿う状態に曲げられた屈曲部の立上り縁部とに、ワークの切断部がそのまま残される。
このように、隣り合う部位の夫々に切断部が残るように構成した結果、基部と屈曲部とからなる羽根部を周方向に沿って最も高密度に配置することができる。よって、羽根部の枚数を増大させ、あるいは、羽根部の面積をより大きく確保して高効率の羽根部材を得ることができる。
本発明に係る羽根部材の第2の特徴構成は、前記屈曲部が、前記立上り縁部の先端部に当該立上り縁部と交差する立上り先端縁部を備えると共に、前記基部が、前記張出し縁部の先端部に当該張出し縁部と交差する張出し先端縁部を備え、前記立上り縁部および前記張出し縁部のうち長さの短い方の縁部において、当該縁部とこれに交差する先端縁部とのなす角度を鈍角に構成した点にある。
本構成のごとく、立上り縁部の長さと張出し縁部の長さとが異なる場合、屈曲部が基部から切り起こされる前のワークにおいては、例えば基部の張出し先端縁部が屈曲部の立上り縁部の途中の位置に交差する状態となる。このとき、基部のうち張出し縁部と張出し先端縁部とのなす角度が鈍角に形成してあるから、その外角、即ち屈曲部の立上り縁部と基部の張出し先端縁部とのなす角度が鋭角になる。本発明の羽根部材は、立上り縁部をワークから直に切り起こすから、切起しの開始位置がこのように鋭角に構成してあれば、切起こしに際して最初の切れ込みが生じ易い。よって、本構成であれば、ワークの切起し作業が極めて円滑なものとなる。
本発明に係る羽根部材の第3の特徴構成は、前記張出し縁部の長さに対して前記立上り縁部の長さを長く構成した点にある。
本構成のごとく、立上り縁部の長さを長くすることで、切起こし作業を行う前のワークにおいては、基部に対して屈曲部が径方向外方に突出することとなる。つまり、屈曲部となる側の長さが基部となる側の長さよりも長くなる。羽根部の形成に際しては、屈曲部の先端部から順次曲げ始めるから、この曲がった部位が基部の張出し先端縁部に達したときには、基部と屈曲部とのせん断方向への相対速度が所定の速度に高まっている。よって、切起こしの開始位置においてワークへの切れ込み発生・進展が容易となり、切起こし作業がより円滑なものとなる。
本発明に係る羽根部材の第4の特徴構成は、前記ホール部から外周に向けて直線状の切起し線が設定され、該切起し線によりワークが切り起こされて、一方の縁部が前記立ち上り縁部となり、他方の縁部が前記張出し縁部となる点にある。
本構成の如く、ホール部から外周に向けて直線状の切起し線が設定され、該切起し線によりワークが切り起こされることで、回転軸芯に沿う屈曲部の立上り縁部と、ホール部から外周に向けて張り出される張出し縁部とを容易に形成することができる。
本発明に係る羽根部材の第5の特徴構成は、前記切起し線の線径が、前記ホール部の孔径よりも小さい点にある。
本構成の如く、切起し線の線径が、ホール部の孔径よりも小さいことで、基部と屈曲部とからなる羽根部を周方向に沿って高密度に配置することができる。
本発明に係る羽根部材1は、例えば自動車のエンジンEに用いられるウォータポンプP等に装着される。当該羽根部材1は、中心側の筒状部2と、この筒状部2から回転軸芯Xに対して径方向外方に突出した複数の基部3と、この基部3の夫々から回転軸芯Xに沿って一方向に曲げられた屈曲部4とを備えており、これらの部材が一体に構成されている。これら基部3と屈曲部4とで一枚の羽根部Hが形成される。以下、図面を参照しながら当該羽根部材1について説明する。
羽根部材1の中央位置には、回転軸芯Xの周りに筒状をなす筒状部2が形成してある。筒状部2のうち回転軸芯Xに沿った一方の端部から回転軸芯Xの径方向外方には複数の基部3を突出形成してある。この基部3は、回転軸芯Xに垂直な平面内に形成してあり、周方向に沿って均等に配置してある。
基部3の夫々からは回転軸芯Xの方向に折り曲げられた屈曲部4が延設してある。この屈曲部4は、回転によって流体に遠心力を付与する部位である。当該屈曲部4は、回転軸芯Xに近い側から外周側に掛けて緩やかにカーブしてある。これにより、流体に対して効果的に遠心力を付与することができる。
図5には、屈曲部4を切り起こす前のワークWの外観を示す。この状態で、中央の筒状部2は既に絞り加工されている。また、合計八つのホール部15を既に加工済みである。図5では、隣り合う羽根部Hどうしの境界に切起し線16を記載してあるが、現実のワークWではこのような線は設けない。
一方、立上り縁部18の外周側端部から回転方向上手側に向けて、やはり略直線状の立上り先端縁部20が形成してある。この立上り先端縁部20は、切起こしが終了した状態では、羽根部材1の軸芯方向に沿った先端部の縁部を構成する。
屈曲部4は切起し線16に対して略直角の面を有する状態に曲げ加工すると加工そのものが容易となる。また、屈曲部4は、流体の搬送効率を向上させるために所定の曲面を備えて構成する。当該曲面は、下側金型と上側金型とが当該屈曲部4を構成するワークWを挟持する状態に型締めされる際に形成される。
このように構成する結果、張出し縁部17と、この張出し縁部17から交差する方向に延出する張出し先端縁部19との角度が鈍角となる。
尚、図5では、立上り先端縁部20は直線状に形成してあるが、これを曲線状に形成し、完成した羽根部材1において径方向の外方ほど傾斜が緩くなるように構成してもよい。
