Abstract: 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.

Abstract: A hydraulic forming machine, including a body provided with a feed inlet penetrating a first mounting surface, a cutting mechanism, a forming die, an ejector arranged on the forming die, and a driving mechanism. The forming die includes a movable die and a fixed die matched with each other. The cutting mechanism and the fixed die are provided on the first mounting surface of the body and respectively at two sides of the discharge end of the feed inlet. The movable die is arranged on the driving mechanism and driven by the driving mechanism to move close to or away from the fixed die in a direction perpendicular to the first mounting surface. The cutting mechanism is configured to cut a blank at an output end of the conveying inlet. The blank cut by the cutting mechanism is extruded between the fixed die and the movable die.

Abstract: A press machine is provided. Two vertical hydraulic cylinders are arranged on an upper beam plate of a press machine body, and the two hydraulic cylinders correspond to workbenches at corresponding positions in a one-to-one correspondence, constituting left and right working units, and a common mechanical drive unit and a common hydraulic drive unit are set for the left and right working units. The mechanical driving unit is composed of a driving motor through an electromagnetic clutch, an electromagnetic brake and lead screw nut driving mechanism driven by a gear pair. According to the load profiles during the working process of hydraulic press machine, the mechanical driving unit or the hydraulic driving unit are selected to provide energy for the two working units. A control method for the press machine, a press machine execution system and a control method for the press machine execution system are further involved.

Abstract: 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.

Abstract: 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.

Abstract: The underlying invention relates in particular to a production module for a production line which is modularly populatable with production modules. In embodiments, provision is made whereby the production module comprises at least one manipulator unit with which a workpiece or a workpiece component is, during the production process, transferable between a deposit position and a production position in the production space of a production module which, for the execution of a production step, is positioned directly downstream in a production direction (R) along the production line.

Abstract: 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.
