A press for producing fine cut parts includes a tool holder, a cross-beam and a tool having a plurality of tool parts, wherein the tool includes a tool block. The tool holder includes a set of transmission devices. The cross-beam is drivingly connected, via the set of transmission devices, to at least some of the tool parts required to produce a fine cut part and arranged in the tool block. The cross-beam is actuated by at least two cross-beam drives.

A press drive device includes a connecting rod having input and output ends. A drive shaft mounts at first and second mounting points using first and second bearing mechanisms, to be rotatable about shaft axis W. Between the bearing points, the drive shaft includes a connecting rod bearing eccentrical in relation to the shaft axis and to which the input end connects. A motor includes a stator connected in a rotationally fixed manner. A rotor supported by a rotor hub is arranged radially within the stator. The rotor hub connects in a rotationally fixed manner directly to the drive shaft without using any step-up or step-down gear. The rotor, the rotor hub, and the drive shaft mount exclusively at the first bearing point and the second bearing point with no additional bearing points.

A torsion shaft structure based multi-link all-electric servo synchronous bending machine, comprising a machine frame, a lower die fixedly connected to the machine frame and used for bending, a slider capable of moving up and down along the machine frame, and an upper die fixedly connected to the slider and cooperating with the lower die to perform bending, wherein the slider is left-right symmetrically connected to drive mechanisms for driving the slider to realize a transmission ratio adjustable motion.

The disclosure relates to a lifting gear for opening and closing a workstation of a packaging machine, wherein the lifting gear includes a stationarily mounted base, a lifting platform mounted to be height adjustable with respect to the base along a lifting axis for supporting a lower tool part of the workstation, and an adjusting mechanism comprising a drive unit and a toggle means on which the lifting platform is mounted, wherein the adjusting mechanism furthermore includes a pressure part coupled with the toggle means and adjustable by means of the drive unit along the lifting axis, wherein by the displacement of said pressure part along the lifting axis, the toggle means can be actuated for a height adjustment of the lifting platform.
