批量冲铜件模具选材层级:T8/T10 碳工钢(万次级)→ Cr12MoV 淬火(10 万次级)→ 硬质合金 YG15/YG20(500 万次级,刃磨一次寿命提升 20–50 倍)。寿命管理用 TPM 记录:刃磨周期按「冲次记录 + 断面光亮带比例 <1/3 即刃磨」判定;刃磨量每次 0.05–0.1 mm,总刃磨量不超凸模总长 15%。硬质合金忌冲击,安装时须配弹性卸料板缓冲。

Die material ladder for high-volume copper work: T8/T10 tool steel (10k strokes), Cr12MoV hardened (100k), tungsten carbide YG15/YG20 (5M+, 20–50× life per grind). Manage life with TPM: grind when stroke counters trip or burnish band drops below 1/3; remove 0.05–0.1 mm per grind, max 15% of punch length lifetime. Carbide hates shock—always mount with spring strippers for cushioning.
