Description
そして、本明細書において、金属板材が加工装置によって変更されたことを加工品という。
その後、前記第2プレス金型31を前記金属板材50に向けて移動させる(S15)。そして、前記第2プレス金型31を1次成形された金属板材50の上面に密着させる。また、前記駆動部22が動いて前記カウンタ金型20を前記金属板材50の底部51に密着させる(図3参照)。
即ち、本明細書において、前記金属板材50はハイドロフォーミング(Hydro forming)によって加工品として変形されてもよい。実施的には、前記金属板材50は部分的なハイドロフォーミング工法(Oリングの外側領域でのみ液圧が作用するためである)によって加工品として変形されてもよい。
また、前記金型枠10から前記第2プレス金型31が分離される過程において、前記第2プレス金型31の空気流路32を介して空気が前記第2プレス金型31と前記金属板材50との間に供給されるため、下降完了された金属板材の形状がそのまま維持される。
他の例として、図7を参照すると、一つのプレス金型を利用して金属板材を加工することができる。この際、加工品の用途に応じて第1プレス金型又は第2プレス金型を使用してもよい。
そして、前記金属板材50は前記カウンタ金型20とプレス金型30,31及び液体の加圧によって変形される(S35)。
図8は、他の部分においては図5の説明と同じであるが、但し金属板材の底部全体を液体が加圧するということにその差がある。よって、以下では本実施例の特徴的な部分についてのみ説明する。
図9を参照すると、一つのプレス金型を利用する場合加工品60は一つの加工完了部62を含み、多数のプレス金型を利用する場合加工品61は多数の加工完了部63,64を含むことになる。
この際、前記ドアライナー82には冷気の漏洩を防止するためのガスケット84を具備してもよい。
