Fields of application

Steel mill > production

The ingot oscillation system prevents the metal from adhering to the ingot mould wall during the cooling process.

Technical implementation and Hänchen share
At an amplitude of 5 mm and a frequency of up to 5 Hz, four cylinders move the ingot mould in the controlled sine. The high-precision double-rod deviation is max. 50 μm.

  • Special I&C technology
  • Connection to central hydraulics
Mechanical engineering > production

The end-of-line machines subject each finished hydraulic cylinder to a final inspection.

Technical implementation and Hänchen share
The respective sequence of the pressure test starts automatically after the product bar code is scanned. The hydraulic pressure supply is designed for 480 bar.

  • Connection to the ERP system
  • Automatic data collection
Automotive > test machine

The vehicle steering test stand simulates loads that occur during the journey.

Technical implementation and Hänchen share
The axial load introduction is performed by cylinders. Sine movements of 2 mm at 50 Hz as well as freely definable setpoint curves simulate the load.

  • Connection of the customer-side measuring system
  • Hydraulic accumulator system for acoustic measurements
Heating engineering > test facility

The material testing machine serves for testing water accumulators for heating systems.

Technical implementation and Hänchen share
Pulsation of up to 20 Hz at 20 bar is applied to the test specimen via a pressure reducer. Normal tap water is used as the test medium.

  • Integration in the process control computer
  • Installation in an existing system
Shipbuilding > test stand

 The heavy load test stand tests the hydrostatic plain bearings of a ship's shaft for pod drives.

Technical implementation and Hänchen share
Hydraulic cylinders simulate the axial and radial loading of the ship's shaft up to 2.5 MN. The shaft is driven by an electric motor.

  • Synchronous measurement acquisition
  • Connection of the customer-side measuring system

Possible applications for Ratio-Drive® Automatic control engineering: Examples

With Ratio-Drive® you can realize the most complex control structures – with hydraulic as well as with electromechanical drives.

Intelligent control technology allows you to increase the performance of your drive, to control forces with greatest accuracy, and reproduce complex process structures. The technology uses software controllers that can easily be parameterized for the application in question via a web interface, and that can also feature very complex control structures.

 

  • Reproducing independently programmed, measured or synthetic operational profiles
  • Synchronizing the movement of several drives
  • Positioning in the micrometer range
  • Oscillations with prescribed amplitudes, frequencies or accelerations
  • Coupling movement and force of the drive
With Ratio-Drive<sup>®</sup> you can realize the most complex control structures – with hydraulic as well as with electromechanical drives.
