Competitive tire production must be highly flexible and able to respond quickly to volatile market demands. Manufacturers need solutions that enable them to optimize the availability of their plants, reduce their total cost of ownership, and improve their time-to-market. In process steps where higher forces are reliably required, the CytroForce hydraulic linear drive from Bosch Rexroth sets new standards in power density, energy efficiency, and quiet operation.
On account of their enhanced performance credentials, CytroForce actuators, which are robustly designed to meet IP65 protection class criteria, are redefining potential fields of application. Depending on the configuration in question, the CytroForce-M, which was the first to be launched, covers forces of up to 1,200 kN, distances of up to 1.0 m and speeds of up to 0.8 m/s. The positioning accuracy is 10 µm and the repetition accuracy is 5 µm.
With the objective of implementing highly efficient and economical solutions also for the rubber and plastics industry, Bosch Rexroth has developed CytroForce, a solution that sets new standard in efficiency, availability and usability. Possible fields of application are wherever central hydraulics are not used, e.g. for cutting tire tapes or the mixing process in rubber production.
In addition, suitable product documentation up to the 2D or 3D CAD model is available. After mechanical installation, the axes only need to be connected electrically.
Maintenance is also simple: with the help of a service kit, even non-specialist service technicians can take fluid samples for laboratory analyses. Even the refilling process, which needs to be carried out from time to time, does not require any specific expertise. The service kits are available for all Bosch Rexroth servo-hydraulic axes (SHAs), including CytroForce.
Condition monitoring and/or predictive analytics can also be conducted by combining the system with Rexroth’s ODiN service, helping to further increase the machine’s availability.
The modular CytroForce is based on the tried-and-tested variable-speed energy-on-demand drive Sytronix. In the case of CytroForce, a manifold and a differential or tandem cylinder are connected to this energy-efficient unit, consisting of servodrive and hydraulic fixed or variable displacement pump. All hydraulic components and interfaces have been flow-optimized with the latest cutting-edge processes. This reduces noise emissions and increases performance whilst minimizing dimensions.
Together with the tank, safety valves and sensors, the CytroForce modules form a highly compact and efficient servo-hydraulic axis with a closed fluid circuit and an energy-on-demand and standardized drive and control concept.
“Our evolutionary solution, available from a single source, is pushing the boundaries in terms of potential applications for hydraulic self-contained actuators“, says Stefan Thienen, Product Manager at Bosch Rexroth. “The cross-industry advantages provide machine and system manufacturers from practically all sectors with new and exciting prospects and the potential to implement improvements with regard to presses, machine tools and many other applications.”
