Abstract: 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.
