| description | To provide a punching press die that is provided with compressed air supply means that blows out compressed air, in the vicinity of a bottom dead point of a slide, through an air blow hole formed in a punching punch, so that scrap floating can be easily avoided, in high-speed pressing of a raw material.SOLUTION: A punching press die 10, which comprises a lower mold 1, a punching die 11 fixed to the lower mold, an upper mold 2 fitted to a slide, and a punching punch 3 that is fixed to the upper mold to form a hole in a raw material W, is formed to blow out compressed air AE through an air blow hole 31 formed in the punching punch in the vicinity of a lower dead point. Between the upper mold and the lower mold are provided an alignment pin 5 that stands up in a vertical direction, a guide push 6 for guiding the alignment pin and a valve mechanism 7 that is actuated when a tip part 51 of the alignment pin is inserted into the guide push. With the valve mechanism closed, the tip part is inserted into the guide push to form compressed air, and then the valve mechanism is opened in the vicinity of the lower dead point, so that the compressed air is blown out through the air blow hole.SELECTED DRAWING: Figure 2
【課題】素材の高速プレスにおいて、孔抜きパンチに形成したエアブロー孔からスライドの下死点近傍で圧縮エアを吹出してカス上がりを簡単に回避できる圧縮エア供給手段を型内に備えた孔抜きプレス型を提供する。【解決手段】下型１と、下型に固定された孔抜きダイ１１と、スライドに装着される上型２と、上型に固定されて素材Ｗに孔を形成する孔抜きパンチ３とを備え、下死点近傍で孔抜きパンチに形成されたエアブロー孔３１から圧縮エアＡＥを吹出すように形成された孔抜きプレス型１０である。上型と下型との間には、上下方向に起立するアライメントピン５と、アライメントピンがガイドされるガイドブッシュ６と、アライメントピンの先端部５１がガイドブッシュに挿入されたときに作動する弁機構７とを備え、弁機構が閉じた状態で先端部がガイドブッシュに挿入して圧縮エアを形成し、下死点近傍で弁機構が開いて圧縮エアをエアブロー孔から吹き出させる。【選択図】 図２ |
