| 摘 要： | 针对传统自由锻造油压机泵控系统发热大以及功率回收率较低等问题，提出了开式变量泵控快锻油压机系统，并根据系统的能量流流动状态，进行了能耗建模分析。以0.6 MN泵控油压机实验平台为依托，进行了常锻工况和快锻工况下的能耗特性实验研究, 得出了常锻工况下的能耗分布规律。实验结果表明：常锻工况下的有用功占系统能耗的50%，其有用功所占比值随负载力的增大而提高；快锻工况下的有用功占系统能耗的40%以上，其有用功所占比值随锻造频率的增大而提高；开式变量泵控快锻油压机系统具有较大的节能优势。

| Abstract: | Aiming at the problems of low power recovery and large heat release of the conventional pump-controlled system free forging hydraulic press, a fast hydraulic forging press with open variable pump-controlled system was proposed, and its energy consumption model was analyzed according to the energy flow. Based on 0.6 MN pump-controlled system free forging hydraulic press experimental platform, laws of energy consumption distribution on regular and fast forging conditions were obtained. The results show that the active power remains 50% of system energy consumption under regular forging conditions, and the ratio of active power increases with load power increasing. The active power remains above 40% of system energy consumption under fast forging conditions, and the ratio of active power increases with the forging frequency increasing. The results verify that the fast hydraulic forging press with open variable pump-controlled system has a great energy-saving advantage. |
