The workbench is fixedly mounted on the bases, the upper dies I and II are fixedly mounted on a pressing head of the pressing machine, the upper end of each ejector rod I is fixedly connected with the corresponding blank holder I, the lower end of each ejector rod I is fixedly connected with the support plate II, the upper end of each ejector rod II is fixedly connected with the corresponding blank holder II, and the lower end of each ejector rod II is fixedly connected with the support plate I. Eight hydraulic cylinders of the hydraulic system are mounted on the support bases, and the support bases are fixed on the bases. Each of the support plate I and the support plate II is supported by four of the hydraulic cylinders, and a hydraulic control system is connected with the hydraulic cylinders through pipelines. The double-support-plate numerically-controlled hydraulic cushion has the advantages that pressure of the two support plates can be adjusted respectively, and double-die production with different pulling depth can be performed; pressure fluctuation is small during working, and quality of stamping parts is good; the cushion is small in size, and nominal blank holder force can be large enough.
