Case: High-volume Copper Terminal Stamping
案例：铜接线端子批量冲压
标签：级进模, 量产, 搭边, 端子
某厂用 6 工级进模（冲孔→落料→弯曲×2→整形→切断）生产 T2 紫铜接线端子，料厚 0.8 mm，冲次 220 次/分。通过优化排样将搭边从 2.0 mm 降至 1.2 mm，材料利用率由 62% 提升至 78%，毛刺控制在 0.05 mm 内。
A plant produced T2 copper terminals on a 6-station progressive die (pierce → blank → bend ×2 → calibrate → cut-off), 0.8 mm stock at 220 strokes/min. Optimizing the layout cut the bridge from 2.0 mm to 1.2 mm, raising material utilization from 62% to 78% with burrs held under 0.05 mm. ---
