Definitions

  • the invention relates to a machine tool, in particular a pipe press, containing a drive, an output shaft, a threaded spindle drive and a linear actuator, wherein a torque generated by the drive can be transmitted to the linear actuator via the output shaft, the threaded spindle drive connected to the output shaft.
  • the forming machines available on the market have a press head driven by a press cylinder.
  • the press cylinder for moving the press head is often driven hydraulically.
  • An electric motor in turn drives a hydraulic pump, which drives the linear movement of the press cylinder.
  • mechanical pressing/cutting and crimping tools are also available on the market, which generate the pressing pressure via a threaded spindle drive in combination with an electric motor instead of hydraulics.
  • the rotary movement of the electric motor is transformed into a linear movement via a threaded spindle.
  • These machine tools often contain a gearbox connected between the spindle and the electric motor in order to reduce the required motor torque and thereby allow the motor to be dimensioned smaller.
  • machine tools known from the prior art with hydraulically driven linear actuators tend to be too complex to develop and to be too large or too long, inefficient and too heavy to handle.
  • machine tools known from the prior art with hydraulically driven linear actuators require a relatively long time for a single work cycle, with a work cycle being able to be a forming or cutting cycle, for example.
  • the object of the present invention is therefore to provide a machine tool, in particular a pipe press, containing a drive, an output shaft, a threaded spindle drive and a linear actuator, in order to solve the problems mentioned above.
  • the object is achieved in particular by providing a machine tool, in particular a pipe press, according to claim 1 containing a drive, an output shaft, a threaded spindle drive and a linear actuator, with a torque generated by the drive being transmitted via the output shaft to the threaded spindle drive connected to the output shaft Linear actuator is transferrable.
  • the machine tool contains an eccentric gear device for torque adjustment between the drive and the threaded spindle drive, the eccentric gear device containing a drive eccentric that can be driven by the drive, an eccentric gear wheel that can be driven by the drive eccentric, a compensating clutch that can be driven by the eccentric gear wheel, for torque transmission from the eccentric gear wheel to the output shaft.
  • the compensating coupling can be designed as a torsionally rigid compensating coupling.
  • an eccentric gear device By using an eccentric gear device, a hydraulically driven linear actuator can be dispensed with, which means that the machine tool can be less complex to develop and smaller, more efficient and easier to handle. Furthermore, the use of an eccentric gear device significantly reduces the duration of a work cycle. In addition, relatively high gear ratios can be achieved in just a single gear stage by using an eccentric gear device. Furthermore, by using an eccentric gear device, very high gear ratios (i.e. 1 to 1000, for example) can be realized in just a single gear stage.
  • the eccentric gear device can also be referred to as a circular thrust gear device or cycloidal gear device.

  • the eccentric gear of the eccentric gear device is driven directly via the drive eccentric.
  • an involute toothing may be contained between a ring gear fixedly connected to a housing and the eccentric gear.
  • involute gearing results in a more efficient rolling movement instead of a sliding movement at the respective contact point of the teeth of the ring gear and eccentric gear. Furthermore, the number of roller bearings required on or on the ring gear can be reduced to a minimum.
  • the eccentric gear wheel has an outer diameter that essentially corresponds to an inner diameter of the hollow gear wheel.
  • a maximum translation between the eccentric gear and the ring gear is given when the number of teeth difference between the eccentric gear and the ring gear is a minimum.

  • the ring gear of the eccentric gear device may be rotatably mounted in the housing.
  • the eccentric gear device can consist at least partially of a metallic sintered material.
  • a sintered material By using a sintered material, the ability of the components to slide, i.e. in particular within the eccentric gear device, can be increased.
