Description
本発明に関する背景技術は、大韓民国公開特許公報第10−2012−0088362号(2012.08.08、発明の名称:車両用ジョイントフランジ)が提示されている。
ジョイントフランジ100は、フランジ10の装着孔12に設置されたパイプ20のシーリング溝24にOリング4が装着された状態で対象物フランジ2の孔に挿入設置されて、締結部材6を通じて対象物フランジ2を貫通してフランジ10の締結孔14に締結されることによって、対象物フランジ2と相互に組み立てられてパイプ20と連結パイプ8が相互に連結されて冷媒などの流体が移送される。
結合部30はパイプ20とフランジ10に設けられ、パイプ20をフランジ10に固定する構成である。
第1拡張溝54、第2拡張溝64および第3拡張溝74に行くほどパイプ20の一端部の長さは短くなりつつ、厚さは次第に拡張される。すなわち、フォーミング成形部材40によりパイプ20の一端部の長さが次第に短くなりつつ、それだけの体積が厚さに転換されながら厚さ拡張部22の厚さが増進されるのである。
フランジ成形段階S20は、パイプ20を設置するための装着孔12を有するフランジ10をダイカストで成形する段階である。
