摘要： A pressing machine is described for plastically deforming a tubular workpiece, in particular a fitting. The pressing machine has a motor, and pressing jaws which are driven by the motor and can apply a force to the workpiece during operation. The pressing machine also has a power transmission unit coupled to the motor and the pressing jaws for transmitting power from the motor to the pressing jaws. The pressing machine also has at least one sensor unit for measuring at least one pressing parameter P and a controller which receives the currently measured value of the pressing parameter P from the sensor unit and determines therewith the pitch or slope of a press parameter curve K of the press parameter P. The controller terminates a pressing operation before reaching a maximum possible pressing force Pmax when the pitch or slope of the press parameter curve K of the press parameter P satisfies a shutdown criterion. Also described is a corresponding method for operating a pressing machine.

摘要： A method of performing pressing on a workpiece using a press machine. The pressing method includes: performing pressing on the workpiece between a lower die and an upper die by causing the upper die to approach the lower die by using the hydraulic cylinder in a state in which the workpiece is disposed between the lower die and the upper die, and performing the pressing on the workpiece between the lower die and the upper die, in a state in which a shape of each of the frame, the lower die and the upper die has a rotationally symmetric shape about the reference axis and in which the workpiece center axis coincides with the reference axis.

摘要： An electro-hydrostatic drive for realizing a rapid movement and a force-building movement, comprising a hydro-machine with variable volume and/or rotational speed, driven by an electric motor, for providing a volume-flow of a hydraulic fluid, a first cylinder with a housing, a piston, a cylinder rod, and a first and a second cylinder chamber, a second cylinder with a piston, a cylinder rod, and a first and a second cylinder chamber, a moveable carrier plate, a pillar, and a clamping apparatus to clamp and/or unclamp the first cylinder to the pillar, where the hydraulic drive has a closed hydraulic circuit, which has, when run, a positive pressure above atmospheric pressure and which, by utilizing the hydro-machine, can pressurize either the first or the second cylinder chamber of the first cylinder and/or the first or the second cylinder chamber of the second cylinder. The moveable carrier plate is connected both to the first cylinder and to the second cylinder. For the force-building movement, the first cylinder is clamped, by the clamping apparatus, to the pillar and one cylinder chamber of the first cylinder is pressurized with the hydraulic fluid, and for the rapid movement, the first cylinder is unclamped, by the clamping apparatus, from the pillar and one cylinder chamber of the second cylinder is pressurized with the hydraulic fluid.

摘要： An actuator device includes two drive units for an actuator output element. The first drive unit has a first piston chamber and a first piston displaceable therein and also first hydraulic means for displacing the piston. The second drive unit has a second piston chamber and a second piston displaceable therein and also second hydraulic or pneumatic means for displacing the piston. The second piston is joined to the actuator output element for conjoint movement therewith and can be coupled to the first piston for thrust, so that the second piston is displaceable in an outward direction by the first piston. The first drive unit is configured for a larger thrust force than the second drive unit, while the second drive unit is designed for a greater stroke speed than the first drive unit.

摘要： Apparatuses for pressing and heating a material and associated methods are disclosed herein. An apparatus of the present technology includes a housing, a pressure component positioned in the housing, a linkage component coupled to the pressure component, a first heating component coupled to the linkage component, and a second heating component positioned adjacent to the first heating component. The linkage component is movable between a first position and a second position. When the linkage component is at the first position, the linkage component is positioned at a first level. When the linkage component is at the second position, the linkage component is positioned at a second level and the linkage component holds the first heating component stationary relative to the second heating component.
