Abstract
Description
[第1実施形態]
図1に示す第1実施形態のホットスタンプ加工装置1は、ワーク(加工対象物)としての金属板材(鉄板)9に対してホットスタンプ加工を行うための装置である。ホットスタンプ加工装置1は、固定部2と、固定部2に対して上下動可能(鉛直方向へ移動可能)に設けられた可動部3と、可動部3を上下動させるための動力を発生するサーボモータ4と、を備える。なお、金属板材9としては、例えばZn-Niメッキ材が用いられる。
パット31は、下面における中央部が上方側にへこんでおり、側方から見た断面形状が、へこみ部分が下方側へ開口した形状に形成されている。パット31の下面は、成形加工の際に、下型21の上面と協働して金属板材9を押圧(成形)する押圧面として機能する。このため、パット31の下面は、下型21の上面と嵌合する形状に形成されている。なお、パット31の内部には、冷却水を流すための冷却水流路31Bが形成されている。
ライナー34は、パット31の上方に配置されており、パット31の上面に当接し、ホルダー33に対するパット31の鉛直方向における位置(上方への移動可能位置)を規制する規制部材として機能する。パット31の上面(ライナー34と対向する側の面)には、階段状の複数段の段差(本実施形態では3段の段差)が形成されている。また、ライナー34の下面(パット31と対向する側の面)には、パット31の上面の段差に嵌合する階段状の複数段の段差(本実施形態では2段の段差)が形成されている。ライナー34は、パット31に対して水平方向(図1でいう左右方向)へ移動可能に支持されている。このため、水平方向におけるライナー34の位置に応じて、ホルダー33に対するパット31の上方への移動可能位置を異ならせることができる。
第1の状態で、パット31が上昇端から成形時の下降端まで下降し(図1に示す状態)、保持時間T1の間、その状態が保持された後、パット31が少し上昇する。この動作により、成形加工が行われる。
[A1]ホットスタンプ加工装置1は、下型21と、下型21に対して鉛直方向へ相対的に移動可能なホルダー33と、ホルダー33に支持され、下型21と協働して金属板材9に対して成形加工を行うパット31と、ホルダー33に支持され、下型21と協働して金属板材9に対して切除加工を行う切刃32と、鉛直方向における、切刃32に対するパット31の相対的な位置を、段階的に切替可能なライナー34及び自動化装置35と、を備える。つまり、成形加工と切除加工とを切り替えてホットスタンプ加工を行うことができ、例えば図4に示すような部品8を製造する場合に、成形加工と切除加工とを1サイクルで完了させることができる。したがって、例えばレーザーで切除加工を行う場合と比較して、短時間で加工を行うことができる。加えて、遅れ破壊を生じにくくすることができる。
図5及び図6に示す第2実施形態のホットスタンプ加工装置5は、第1実施形態のホットスタンプ加工装置1と同様の固定部51、可動部52及びサーボモータ53を備える。固定部51は、第1実施形態と同様の下型511を備える。可動部52は、第1実施形態と同様のパット54と、切刃522と、ホルダー523と、ライナー55と、自動化装置525と、を備える。
なお、第2実施形態では、下型511が第1の金型の一例に相当し、パット54が第2の金型の一例に相当し、切刃522が切断部材の一例に相当し、ホルダー523が可動体の一例に相当する。また、ライナー55及び自動化装置525が切替装置の一例に相当し、ライナー55が規制部材の一例に相当し、自動化装置525が駆動装置の一例に相当する。また、鉛直方向が接近離間方向の一例に相当する。
図8に示す第3実施形態のホットスタンプ加工装置6は、基本的には第2実施形態のホットスタンプ加工装置5と同様の構成であるが、第2実施形態のパット54及びライナー55に代えて、図8及び図9A等に示すパット64及びライナー65を備えている点で相違する。
図10に示す第4実施形態のホットスタンプ加工装置7は、基本的には第2実施形態のホットスタンプ加工装置5と同様の構成であるが、第2実施形態のパット54及びライナー55に代えて、図10及び図11A等に示すパット74及びライナー75を備えている点で相違する。
以上、本発明の実施形態について説明したが、本発明は、上記実施形態に限定されることなく、種々の形態を採り得ることは言うまでもない。
