MANUFACTURING DEVICE OF POWDER COMPACT, MANUFACTURING METHOD OF POWDER COMPACT, MANUFACTURING METHOD OF TOOL DERIVED FROM POWDER COMPACT, AND TOOL DERIVED FROM POWDER COMPACT

To provide a manufacturing device and a manufacturing method for manufacturing a powder compact, which can manufacture a powder compact molded with a spiral groove, a boss projecting portion, and the like, and can simplify the device to reduce costs.SOLUTION: A manufacturing device 10 is equipped with a dice 20 having a cavity 21, a lower punch 30, and an upper punch 50. The upper punch 50 has a first punch 60 and a second punch 80, and the lower punch 30 and the upper punch 50 are rotatably supported. A projecting portion 25 presses a groove portion 35 with the lifting/lowering action of the dice 20, thereby co-rotating the lower punch 30. The first punch 60 and the second punch 80 are lifted and lowered, and the first punch 60 and the second punch 80 are controlled to deviate one end of the first punch 60 and one end of the second punch 80.SELECTED DRAWING: Figure 3 【課題】螺旋状の溝及びボス突部等を成形した粉末成形体を製造でき、装置を簡素化してコスト低減を図れる粉末成形体を製造するための製造装置及び製造方法を提供する。【解決手段】この製造装置１０は、キャビティ２１を有するダイス２０と下パンチ３０と上パンチ５０とを備え、上パンチ５０は第１パンチ６０と第２パンチ８０とを有し、下パンチ３０及び上パンチ５０は回転可能に支持され、ダイス２０の昇降動作に伴って、突部２５が溝部３５を押圧することで、下パンチ３０が連れ回りするように構成され、第１パンチ６０及び第２パンチ８０を昇降動作させ、第１パンチ６０の一端と第２パンチ８０の一端とを位置ずれさせるように第１パンチ６０及び第２パンチ８０が制御される。【選択図】図３
