采用伺服压力机实现冲压节能的定量研究

为了研究伺服压力机在冲压加工中的节能效果，对一台用于洗衣机外壳冲压生产的6300 kN多连杆机械伺服压力机的整机能耗和滑块做功进行了定量测量，并对其能耗情况进行了计算分析。结果显示，被测压力机在完成伺服冲压工艺要求的前提下，整机单次能耗为0.094 5 kW·h，单次比能耗为15.0×10^-6 kW·h/kN，从整机输入到滑块的能量传递效率为39.5%。由此可得，被测压力机单次能耗与所替代的传统8000 kN油压机相比降低86.4%，能量传递效率比文献数据提高至少25%。结果表明，采用伺服压力机在实现高性能伺服冲压工艺基础上取得了显著的节能效果。

Quantitative study on energy saving of stamping by servo press

To investigate the energy saving effect of servo press in stamping production, the energy consumption and the slide power of a 6300 kN multi-link mechanical servo press used in the stamping production of washing machines were quantitively measured, and the energy consumption was calculated and analyzed. The results showed that the single energy consumption of the tested press was 0.094 5 kW·h, and the single specific energy consumption was 15.0×10^-6 kW·h/kN. The energy transfer efficiency from the machine input to the slide was 39.5%. Based on these results, the single energy consumption of the tested press was observed to be 86.4% lower than that of the traditional 8000 kN hydraulic press replaced, and the energy transfer efficiency was at least 25% higher than that observed in the literature data. Furthermore, along with its high shaping performance, the proposed method of using servo press technology has also achieved remarkable energy saving effect.
