Zusammenfassung: | To provide a press molding device and a press molding method that can enhance productivity.SOLUTION: A press molding device 10 comprises: a die 25 on which a work-piece 200 is placed; a punch 70, provided to be movable back and forth with respect to the die 25, which punches out a product from the work-piece 200; and a back pressure device 30 having a pressing member 35 provided inside the die 25, which applies back pressure to the work-piece 200 by energizing the pressing member 35 toward the punch 70. Further, the pressing molding device 10 comprises a lift-up mechanism 40 that lifts up the work-piece 200 to above the die 25 when the punch 70 retreats from the die 25, and a delaying device 120 that delays upward movement of the pressing member 35 in comparison with retreating movement of the punch 70 when the punch 70 retreats from the die 25.SELECTED DRAWING: Figure 1
【課題】生産性を高めることができるプレス成形装置及びプレス成形方法を提供する。【解決手段】プレス成形装置10は、ワーク200が載置されるダイ25と、ダイ25に対して進退可能に設けられ、ワーク200から製品を打ち抜くパンチ70と、ダイ25の内部に設けられる押圧部材35を有し、押圧部材35をパンチ70に向けて付勢することでワーク200に背圧を付与する背圧装置30とを備える。また、プレス成形装置10が、パンチ70がダイ25から退避する際に、ワーク200をダイ25の上方に持ち上げるリフトアップ機構40と、パンチ70がダイ25から退避する際に、パンチ70の退避動作に対して押圧部材35の上昇動作を遅延させる遅延装置120とを備える。【選択図】図1 |
