Abstract
【解決手段】曲がり部材30の長さ方向の曲がりに対応する曲がり輪郭形状にしたブランク1,2を、前記曲がり部材の断面形状の分割部分に対応する断面形状に折り曲げる曲げ工程と、前記曲げ工程により得られた2つ(あるいは3つ以上)の部材10,20を接合する接合工程とを有する。
【選択図】図1
Description
(請求項1) 金属単板からなるブランクを成形して曲がり部材を得る曲がり部材成形方法であって、前記曲がり部材の長さ方向の曲がりに対応する曲がり輪郭形状にしたブランクを、前記曲がり部材の断面形状の分割部分に対応する断面形状に折り曲げる曲げ工程と、前記曲げ工程により得られた2つ以上の部材を接合する接合工程とを有することを特徴とする曲がり部材成形方法。
(請求項2) 前記曲げ工程の前に、前記ブランクに折り目をつけ、あるいはさらに切れ目を入れることを特徴とする請求項1に記載の曲がり部材成形方法。
(請求項3) 請求項1または2に記載された曲がり部材成形方法を用いて製造されてなる曲がり部材。
(請求項4) 請求項1または2に記載された曲がり部材成形方法を用いて、曲がり部材を製造することを特徴とする曲がり部材製造方法。
また、図1〜図6に示した例は、図9(a)に示す部材断面形状への成形例であるが、本発明はこれに限定されるものではなく、例えば図9(b)のように、図9(a)を左右反転した部材断面形状への成形や、図9(c)のように、構成部材20のみフランジ2Fを曲げた部材断面形状への成形等々に対しても自明に適用できる。なお、図7、図8に示した例は、図9(d)に示す部材断面形状への成形例である。
さらに、本発明では、曲げ加工の際に前記折り曲げ部の位置精度を向上させるために、ブランクにおける前記山折り、谷折りの箇所に、予め折り目をつけることが好ましい。なお、折り目は、曲げ加工部に対応する箇所の全部にわたって(連続的に)つけることのみに限定されるものではなく、場合に応じて当該箇所の一部のみに(断続的に)つけてもよい。この折り目をつける加工方法には、コイニング等が好ましく用いうる。また、ロール表面につけた凹凸形状を連続的に材料の表面に転写していく方法も挙げられる。かかる折り目の好適形態として、図10(d)に示すようなV溝を、線状(a)、破線状(b)または点線状(c)、あるいはこれらを組み合わせた複合線状に設けた形態が挙げられる。ここで、V溝の深さは金属板厚み(略して板厚)の20%以下が好ましい。V溝の深さが板厚の20%を超える場合は、自動車骨格部材等で必要とされる部材強度の低下、あるいは折り曲げ部に割れを発生させる可能性があり、さらに高強度の金属材料においては、溝を深くすること自体が容易ではなく、生産面やコスト面に大きな問題があるためである。
また、折り曲げの際に局部的に過大な伸びまたは縮み変形加工が加わって割れまたはしわが発生する危険性が高いと予想される局所(例えばブランクのフランジ対応箇所において過大な伸びまたは縮みフランジ加工を受けそうな複数の局所)が存在する場合、かかる局所に予め切れ目を入れておくと、割れまたはしわの発生をさらに確実に予防できて好ましい。
1F,2F フランジまたはフランジ対応箇所
10,20 本発明に係る曲がり部材を構成する部材
30 本発明に係る曲がり部材(成形目標)
50 従来プレス成形による曲がり部材(添え符号A,Bは曲がり部材50を構成する部材)
