Abstract: A punch press includes a die, a punch, a support that supports the punch, a shifting member, and a rotating mechanism. The shifting member includes an opposing surface that opposes the punch. The shifting member is movable toward and away from the die together with the support and the punch and rotatable about an axis extending in a direction in which the shifting member moves toward and away from the die. The shifting member includes a recess in the opposing surface. The rotating mechanism rotates the shifting member about the axis to shift the shifting member between an abutment position where the basal end surface of the punch is abut against the opposing surface and a retraction position where the basal end surface of the punch is retracted into the recess.

Abstract: 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.

Abstract: This disclosure relates to methods and apparatuses for punching workpieces. A punching tool is configured to move during a punching stroke along a stroke axis towards a workpiece to be punched. The punching tool is configured to move away from the punched workpiece during a return stroke. The punching tool includes first and second components configured to be coupled hydraulically for concurrent movement along the stroke axis. The punching tool includes a punching drive for moving the first component along the stroke axis. The punching apparatus is configured to move the second component relative to the first component at a first transmission ratio during the punching stroke. The punching apparatus is configured to move the second component relative to the first component at a second transmission ratio in response to a reaction force of the workpiece exceeding a threshold value of the punching drive during the punching stroke.

Abstract: A mechanical, vibration-preventing means to be used on mechanical and hydraulic presses, bar cutters, shearing machines and the like preferably cyclicly working machine tools with a pulse-like pressing process is adapted to absorb the stroke at punching and cutting in plates, bars, and the like articles of metal, plastics or another material by the resilient energy deriving from the deflection of the machine frame instead of being converted into vibrations and noise immediately after break through of the material being converted directly into rotational energy in a flywheel through a roller screw connection. This roller screw connection transforms the translatory movement of the machine tools into rotation. A free engine clutch ensures that the flywheel--accelerated as a consequence of the above procedure--does not start to pull at the structure of the machine during the reverse movement of the machine tool by a force almost as great as the process force immediately before the energy is received by the flywheel, because only very few machine tools of the above type can bear such tensile forces. The energy supplied to the flywheel is subsequently dissipated before the next cycle of the machine.
