Abstract
Description
壁厚さが1mmの外径63.5mm(2.5インチ)雌型パイプを、65.5mmに拡大させ、拡大長さをパイプの端部から30mmにした。パイプの内側に深さ1.0mm、幅10mmの溝を形成し、溝の中心線を開端から約12mm離した。対応する雄型パイプは、拡大されていない挿入端部に形成された同じ寸法の溝を有した。雄型パイプおよび雌型パイプの両方に入口穴および出口穴をあけた。溝が整合するように、雄型パイプを雌型パイプに挿入した。接着剤を加える前に、160°F(71℃)のオアカイト(Oakite)164苛性溶液中に10分間浸漬することによって、パイプを脱脂した。ミネソタ・マイニング・アンド・マニュファクチャリング・コーポレイション(Minnesota Mining and Manufacturing Corporation)から入手可能な二液性構造用接着剤、SA8051の10:1混合物を、8〜24スタティックミキサーノズルによって混合し、注入穴を通して両方の空洞に注入した。結果として生じるアセンブリを、24時間、周囲条件で保持し、次に、171℃で、強制空気オーブン内に30分間配置した。次に、硬化したアセンブリを、5000psi(34MPa)で、基本的に楕円形の形状から本質的に矩形の形状に、首尾よくハイドロフォーミングした。ハイドロフォーミング後、接合部は漏れがなかった。
雌型パイプ(実施例1とほぼ同じ寸法を有する)の一端を、雄型パイプを受けるために拡大した。雌型パイプに入口穴および出口穴を設けた。0.50mm×10.0mmの溝を雄型パイプに設け、雄型パイプを雌型パイプに挿入した。雄型パイプの他の寸法は、実施例1で説明されたのとほぼ同じであった。洗浄、接着剤注入、硬化、およびハイドロフォーミングを、実施例1で説明されたように行った。ハイドロフォーミング後、接合部は、耐漏れ性であった。
上記実施例1と同様に、雄型パイプおよび雌型パイプの両方に溝を形成した。組立てると、溝は互いに10.0mmずれた。各溝に対応する入口穴および出口穴を雌型パイプに設けた。洗浄、接着剤注入、硬化、およびハイドロフォーミングを、実施例1で説明されたように行った。ハイドロフォーミングすると、接合部は、耐漏れ性であった。
本発明の実施形態と関連して、ロボットによって組立てられた20までの接合部からなるフレームに、接着剤を注入し、次に、クラムシェル加熱コイルによる誘導加熱サイクルにかけることができる。この実施形態において、30秒の加熱サイクルが、接着剤を完全に硬化させるのに十分であり得る。次に、ユニット全体を、所望の最終構成に首尾よくハイドロフォーミングすることができる。本発明を用いることによって、フレーム構造を形成するのに必要な人力および関連する費用を著しく低減できることが、この実施例からわかる。
