Abstract: Disclosed is a lightweight two-crossbeam high-speed free forging hydraulic press. The hydraulic press includes a fixed crossbeam, a movable crossbeam, a column, and a return oil cylinder. By integrating a hydraulic cylinder with a through hole for the column to slide, an annular hydraulic cylinder is formed between the movable crossbeam and the column, and no hole is required to be specially provided on the movable crossbeam for mounting the hydraulic cylinder. Therefore, the rigidity, strength and bending resistance of the movable crossbeam serving as an upper crossbeam or a lower crossbeam can be effectively guaranteed, the crossbeam structure is simplified, and the manufacturing difficulty is reduced. Meanwhile, compared with the existing hydraulic press of a three-crossbeam structure, the two-crossbeam hydraulic press can greatly reduce the overall dimension and mass of the high-speed forging hydraulic press, reduce the overall height of the hydraulic press.

Abstract: An improved forging process includes the steps of pre-heating the top and bottom dies of a forging press to a specified temperature, and maintaining both dies at the specified temperature during subsequent forging operation with closed-loop temperature control systems. The top and bottom forging dies are each coupled to a dedicated thermic fluid heater, the temperature of each die is individually measured and compared to a respective target temperature, and the respective thermic fluid heaters are controlled in relation to detected deviations of the measured temperatures from the target temperatures. Compressor wheel preforms produced according to this process consistently exhibit primarily radial grain orientations that exactly match the expected values.

Abstract: A hydraulic machine for operation such as for pressurizing a workpiece and molding products from materials by using a reciprocation mechanism comprising a hydraulic cylinder unit. The cylinder unit comprises two types cylinder chambers having different cross-sectional areas, and a third or plural cylinder chambers. Hydraulic oil sent out from a hydraulic pump driven by a servo motor, is fed through a hydraulic circuit into the cylinder unit. The shifting position of the reciprocation movement is detected, and path switching in the hydraulic circuit and revolving operation of the servo motor are controlled on the basis of the detected shifting position. In case the reciprocation movement is used for pressurizing a workpiece by a die, the hydraulic oil is fed to the cylinder chamber for forward of small cross-sectional area until slightly before the die comes into contact against the workpiece, and the die shifts at high speed relative to a workpiece. Subsequently, the path switching is done to lead the hydraulic oil into the cylinder chamber of large cross-sectional area, and the die moves at a low speed relative to the workpiece.
