Description
図1(a)に示すように、一方の金属部品Wを第1保持ヘッド7に、他方の金属部品Tを第2保持ヘッド13にそれぞれ取付けて、一対の金属部品W,Tの各接合面Wa,Taを対向させる。次に、第3アクチュエータ25の駆動によりスライダ21を下方向へ移動させることにより、図1(b)に示すように、加熱コイル27を一対の金属部品W,Tの各接合面Wa,Taの間の領域に進入させる。そして、高周波電源から加熱コイル27に高周波電流を供給することにより、図1(c)に示すように、加熱コイル27によって一対の金属部品W,Tの各接合面Wa,Taを加熱する(図5参照)。ここで、一対の金属部品W,Tの劣化を防止するために、一対の金属部品W,Tの各接合面Wa,Taの温度が金属部品W,Tの材料の結晶成長温度又は変態温度等を超えないようにしておく。
加熱工程の終了後に、第3アクチュエータ25の駆動によりスライダ21を上方向へ移動させることにより、図2(a)に示すように、加熱コイル27を一対の金属部品W,Tの各接合面Wa,Taの間の領域から退避させる。そして、一対の金属部品W,Tの各接合面Wa,Taを対向させた状態で、第1アクチュエータ11の駆動により一方の金属部品Wを他方の金属部品T側(後方向)へ第1保持ヘッド7と一体的に移動させることにより、一対の金属部品W,Tの各接合面Wa,Taを接触させる(図4参照)。
接触工程の終了後に、図2(b)に示すように、一対の金属部品W,Tの各接合面Wa,Taを対向接触させた状態で、第2アクチュエータ17の駆動により他方の金属部品Tを前記基準の高さ位置を中心として上下方向(対向方向に直交する方向)へ第2保持ヘッド13と一体的に往復移動(往復振幅α)、換言すれば、一方の金属部品Wを上下方向へ他方の金属部品Tに対して相対的に往復移動させつつ、第1アクチュエータ11の駆動により一方の金属部品Wを他方の金属部品T側へ押圧する。これにより、図2(c)に示すように、一対の金属部品W,Tの各接合面Wa,Taから酸化物又は汚れ等をバリBとして排出しつつ、摩擦熱によって一対の金属部品W,Tの各接合面Wa,Taを軟化させることができる。そして、一対の金属部品W,Tの寄り量(変位量)mが目標の寄り量t1(図5参照)よりも小さく設定した目標前の寄り量t2(図5参照)になると、第2アクチュエータ17の駆動を停止して他方の金属部品Tの往復移動を停止する(図5参照)。
第1接合工程の終了後に、図3(a)に示すように、一対の金属部品W,Tの寄り量mが目標の寄り量t1になるまで、第1アクチュエータ11の駆動による一方の金属部品Wの押圧動作を継続して、一対の金属部品W,Tの各接合面Wa,Taを据え込む(図5参照)。これにより、図3(b)に示すように、一対の金属部品W,Tの各接合面Wa,TaからバリBとして排出しつつ、一対の金属部品W,Tの各接合面Wa,Taを接合することができる。換言すれば、一対の金属部品W,Tからなる接合構造体JSを製造することができる。
