A radial press is provided having a first and a second ring structure extending about a press axis. Multiple press bodies are arranged about the press axis between the ring structures and are movably supported on support surfaces paired with the ring structures. The axial distance between the two ring structures can be changed using a drive system having a plurality of actuators oriented parallel to the press axis and distributed about the press axis. The support surfaces paired with one of the two ring structures are inclined relative to the press axis, and the press bodies are guided in a forced manner relative to the two ring structures in that the press bodies are equipped with guide grooves into which guide bodies engage.

A radial press is provided having a first and a second ring structure which extend around a press axis and a plurality of pressing elements, which are disposed around the press axis and are translatably supported on supporting surfaces associated with the ring structures. The axial distance of the two ring structures from each other can be changed using a hydraulic drive system, which has a plurality of hydraulic cylinder-piston units oriented parallel to and distributed around the press axis, the cylinder of each cylinder-piston unit being coupled to a first of the two ring structures and the piston rod of each cylinder-piston unit being coupled to the second ring structure. At least the supporting surfaces associated with one of the two ring structures are oriented at an inclination with respect to the press axis. An electromechanical rapid adjustment drive comprising a plurality of adjusters is also provided.

The press machine includes: a hydraulic cylinder configured to drive a slide; a plurality of hydraulic pumps/motors; a first port of each of which is connected to a first pressurizing chamber of the hydraulic cylinder; a plurality of servomotors axially connected to rotating shafts of the respective hydraulic pumps/motors respectively; a low-pressure accumulator to which second ports of the hydraulic pumps/motors are each connected; a high-pressure accumulator connected to a second pressurizing chamber of the hydraulic cylinder; and a slide position controller configured to control the servomotors so that a position of the slide matches a position corresponding to a slide position command signal based on the slide position command signal from a slide position commander and a slide position signal from a slide position detector.

A portable press configured to selectably apply either compression or expansion forces to objects or workpieces, thereby permitting multiple functions such as pressing, bending, fixturing, spreading, lifting, and position holding assistance in fabrication applications to the objects or workpieces.

A press device having a cradle, a base plate, a fracturing device, an actuator, a switch, and a body. The base plate is located at a first end of the cradle. The fracturing device is proximally located at a second end of the cradle. The cradle is adapted to work in communication with the base plate to maintain alignment between the baseplate and the fracturing device. The actuator is proximally located to the second end of the cradle. The switch is operably connecting the actuator to the fracturing device. The body holds the cradle, base plate, fracturing device, actuator driven ram, and switch. The preferred embodiment uses a hydraulic ram.
