Servo-direct Press Multi-speed Profiles
伺服直驱锻压机多段变速成形
标签：伺服压机, 多段速, 精锻, 节能
伺服直驱压机可编程滑块速度曲线：接触前快进（300 mm/s）、成形段减速（5–15 mm/s）、回程快退，铜接头锻件充型率提升 8–12% 且飞边减小。多段速尤其利于薄法兰类黄铜件——低速段让金属充分流入窄槽再快速顶出保压。相较传统摩擦压力机节能 40%，噪声降 10 dB；编程要点是拐点位置按试锻的行程-载荷曲线微调。
Servo-direct presses program the ram speed profile: fast approach (300 mm/s), slow forming (5–15 mm/s), fast return—improving fill of copper terminals by 8–12% with less flash. Multi-speed profiles suit thin-flange brass parts: the slow zone lets metal fill narrow ribs, then a quick dwell ejects. Versus friction screw presses: 40% energy savings and 10 dB less noise; tune profile knee points against the stroke-load curve from trial blows. ---
