Description

【０００１】
本発明は、請求項１の上位概念部に記載した、溶接された金属薄板冷却通路を備えたリング支持体を製造するための方法に関する。
【０００２】
このような形式のリング支持体は、例えばドイツ連邦共和国特許第１９７５００２１号明細書、米国特許第４９０７５４５号明細書、特開平５−２４０３４７号公報又はドイツ連邦共和国実用新案登録第７２１２５６０号明細書により公知である。この場合、金属薄板冷却通路を備えたリング体は閉じた状態で鋳込まれて、ピストンの製造後にはじめて冷却オイル供給用の開口が穿孔によって形成される。金属薄板冷却通路の材料は一般的にはオーステナイト鋼より成っているので、冷却通路の穿孔及びばり取りは困難である。
【０００３】
そこで本発明は、冒頭に述べた形式の方法において、冷却通路に開口を形成するための簡単な手段を提供することである。
【０００４】
この課題を請求項１の特徴部によって解決される。有利な実施態様は従属請求項に記載されている。
【０００５】
冷却通路リング支持体を鋳包む前に開口を形成することがより簡単である。アルフィン前処理（Ａｌｆｉｎｖｏｒｂｅｈａｎｄｌｕｎｇ）の際に金属薄板冷却通路内に侵入する溶融物は不都合ではないことが証明されている。何故ならばこの溶融物は、アルフィン浴から冷却通路リング支持体を取り除いた後で十分に流出するからである。
【０００６】
鋳型内でピストンを製造する際に、冷却通路リング支持体は有利には主軸によって保持され、この主軸は同時に金属薄板冷却通路の開口を閉鎖するようになっている。
【０００７】
本発明を以下に図面を用いて詳しく説明する。
【０００８】
図１は、鋳包む前に製造された、金属薄板冷却通路及び開口を備えた本発明によるリング支持体である（横断面図）。
【０００９】
リング支持体１は、外側の保持リング２と内側３とを有しており、この内側３は、金属薄板リング若しくは金属薄板冷却通路５と共に、内燃機関のためのピストンの閉鎖された冷却通路を形成している。リング支持体１と金属薄板リング５とは、互いに溶接されている。
【００１０】
金属薄板リング５内には複数の開口４が形成されており、これらの開口４で以て冷却通路リング支持体は後で、鋳型の主軸（Ｐｉｎｏｌｅ）に差し込まれる。この場合、主軸は内部が排気されていて、主軸の直径は、ピストンの鋳包み成形時に溶融物が金属薄板冷却通路内に十分に侵入するのを妨げないように、開口４に合わされている。
【図面の簡単な説明】
【図１】 鋳包む前に製造された、金属薄板冷却通路及び開口を備えた本発明によるリング支持体の横断面図である。
