A path-controlled press, with at least one drive shaft having a driver that is eccentric relative to a shaft axis, and a sliding block, wherein the sliding block is driven by the driver to perform a forcibly actuated movement During the execution of a pressure stroke, the sliding block is guided on at least one sliding surface on the pressure side in relation to a pressure-side surface of a slide guide. The sliding block has a sliding surface on the pulling side opposite the sliding surface on the pressure side, which is guided on a surface of the slide guide on the pulling side. The sliding surface on the pressure side of the sliding block has a concave or convex curvature. The sliding surface on the pulling side of the sliding block has another respective concave or convex curvature.

A mechanical press, with at least one drive shaft having a driver that is eccentric with respect to a shaft axis, and a sliding block. The sliding block is driven by the driver to perform a forcibly guided movement. During an execution of a pressure stroke, the sliding block is guided on at least one sliding surface on the pressure-input side opposite to a pressure-input-side surface of a slide guide. The sliding block has a sliding surface on the pressure-output side lying opposite to the pressure-input side surface, this surface being guided on a pressure-output-side surface of the slide guide, wherein the sliding surface on the pressure-input side of the sliding block has a concave or convex curvature. The sliding surface on the pressure-output side of the sliding block has the opposite concave or convex curvature, respectively.

A punching device includes a body, a drive unit connected to an upper part of the body, and a cam block that moves in a horizontal direction in the interior of the body under a driving action of the drive unit. A second rotating roller, which is connected to a rod, is inserted in a second cam groove of the cam block. The second cam groove includes first and second groove portions inclined at predetermined angles with respect to the direction of movement of the cam block, such that when the rod descends downwardly toward a workpiece, a second rotating roller moves from the second groove portion to the first groove portion having a smaller angle of inclination, whereby the driving force transmitted to the rod is boosted in power.

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 machine tool for processing workpieces comprises a stroke drive device with a pressing tool, with a motorized drive including two motorized drive units which are controlled independently and wedge gear elements between the motorized drive and the pressing tool. The wedge gear elements comprise two drive-side wedge gear elements, each one being associated with a motorized drive unit, and two output-side wedge gear elements attached to the pressing tool, with each output-side wedge gear element opposite to an associated respective drive-side wedge gear element and forming a gear element pair.
