Abstract
Description
実施の形態1.
図1は、本発明の実施の形態1による成形材製造方法によって製造される成形材1を示す斜視図である。図1に示すように、本実施の形態の成形材製造方法によって製造される成形材1は、胴部10とフランジ部11とを有するものである。胴部10は、頂壁100と、頂壁100の外縁から延出された周壁101とを有する筒状の部分である。頂壁100は、成形材1を用いる向きによっては底壁等の他の呼ばれ方をする場合もある。図1では胴部10は断面真円形を有するように示しているが、胴部10は、例えば断面楕円形や角筒形等の他の形状とされていてもよい。例えば頂壁100からさらに突出された突部を形成する等、頂壁100にさらに加工を加えることもできる。フランジ部11は、胴部10の端部(周壁101の端部)に形成された板部である。
一方、図7の一点鎖線より右側に示すように、第1中間体20の外縁部に対して絞り加工を行っているときは、フランジ径が縮小する。この時は、ダイ40と絞りスリーブ42との間の金型隙間の間隔を一定として、フランジ部に相当する領域を成形することにより、しわや座屈の発生を防止することができる。
・フランジ部11に相当する領域のしごき率:-50~60%
・ダイ40の先端角度:45°
・絞りスリーブ42の肩半径:5mm
・プレス油:TN-20
・ダイ、パンチの材質: SKD11(HRC60)
表1に、しごき率とフランジ成形評価の関係を示す。ここで、第1中間体のフランジの平均板厚は、2.0mmであった。
なお、しごき率の定義は次の式(第1式)のとおりとする。ここでは、しごき加工前の板厚として第一中間体のフランジ平均板厚の値を用いることができ、しごき加工後の板厚として金型隙間の間隔の値を用いることができる。
次に、図8は、第1中間体から製造された成形材の板厚分布を示すグラフである。また、図9は、図8の板厚測定位置を示す説明図である。
初回の絞り加工のうち、成形材の胴部に相当する領域に対して絞り加工を行うときは、ダイと絞りスリーブとの間を開放して材料を挟まないようにして、周壁部の板厚減少を抑制する。そして、絞り加工が進んで、成形材のフランジ部に相当する領域がダイと絞りスリーブの間の最近接部に到達したタイミングで、ダイと絞りスリーブの間の金型隙間の間隔をそれ以降一定として成形することで、最終の成形材においてフランジ部の厚みを薄くできることがわかる。しごき加工を行う絞り抜け加工を行った成形材(本発明)と従来の普通絞り方法による成形材(比較例)の外形を同寸法とした場合、発明例の重量は比較例の重量よりも、10%ほど軽かった。
