摘要： 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.

摘要： 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.

摘要： A large caliber ring forging apparatus which is able to uniformly forge a ring blank. The apparatus includes a vertical cylinder device (4) adapted such that a vertical ram (4a) thereof is pressurized by a source of pressurization and a horizontal cylinder device (5) adapted such that a horizontal ram (5a) is allowed to execute its forward operation by a pressurized liquid supplied from the vertical cylinder device (4). An anvil (6) is removably secured to the horizontal ram (5a) and to a return cylinder device (7) connected to a hydraulic pressure supply source (8) for returning the anvil 6 to a return position. Disposed in opposition to the anvil is a mandrel (9) used to forge a ring blank (15) and supported by upper and lower tension bars (3, 11). A table roller device (14) supports the ring blank and rotationally drives the ring blank (15). A plurality of the above-mentioned vertical cylinder devices (4) are disposed in a horizontal direction and a plurality of the above-mentioned horizontal cylinder devices (5) are disposed in a vertical direction. The respective vertical cylinder devices 4 are connected to the separate horizontal cylinder devices 5 by means of separate liquid passages (10a, 10b) and the operation strokes of each set of vertical/horizontal cylinder devices (4, 5) are set to be equal to one another.
