METAL COMPONENT MANUFACTURING DEVICE, METAL COMPONENT MANUFACTURING METHOD AND MOTOR MANUFACTURING METHOD

To provide a metal component manufacturing device which can prevent cracks that occur in a metal workpiece from forming deeper than a tip of a punch, can control a shape of a deep groove formed in the metal workpiece while splitting the metal workpiece by use of the punch.SOLUTION: A metal component manufacturing device 1 comprises a first punch 10 including a first tip 13, and a guide member 20 which is so located as to face a metal workpiece 40 with a space therebetween. By splitting the metal workpiece 40 into a first metal portion 46 and a first metal piece 47 by use of the first punch 10, a deep groove 48 is formed. The guide member 20 contacts the first metal piece 47, and guides the first metal piece 47.SELECTED DRAWING: Figure 6 【課題】金属ワークに発生する亀裂がパンチの先端よりも深く発生することを抑制し得るとともに、パンチを用いて金属ワークを割裂加工しながら金属ワークに形成される深溝の形状を制御し得る金属部品製造装置を提供する。【解決手段】金属部品製造装置１は、第１先端１３を含む第１パンチ１０と、金属ワーク４０に間隔を空けて対向して配置されるガイド部材２０とを備える。第１パンチ１０を用いて、金属ワーク４０を第１金属部分４６と第１金属片４７とに割裂することによって、深溝４８が形成される。ガイド部材２０は、第１金属片４７に接触して第１金属片４７をガイドする。【選択図】図６
