Voith at EuroBLECH 2018: Progressive hydraulic solutions
- PDSC self-contained hydraulic press drive with a press force of up to 10,000 kN significantly increases productivity
- PSH press drive offers up to 60% reduction in energy consumption When combined with the CSH die cushion drive, energy savings can be increased to as much as 80%
- New CLSP self-contained servo drive significantly reduces the connected load through automatic, load-dependent shifting
Self-contained PDSC hydraulic press drive increases efficiency while conserving resources
The hydraulic PDSC press drive delivers high power density and precision force and position control as well as wear-free operation and automatic, load-dependent gear shifting. The maximum press force of 10,000 kN, which is provided by variable speed internal gear pumps without using valves, can be scaled to meet individual requirements. The gear shifting results in very high energy savings combined with a very low connected load. In addition, the unit only has a few electrical connections, does not need a hydraulic power pack and therefore requires only a few components and a minimal supply of oil. The integrated control technology also allows user programming of presses, process parameters and motion profiles.
The PSH servo hybrid press drive was developed jointly by Voith and Siemens. It offers highly flexible pressing processes due to the use of servo pumps for control, along with optimum speed and force adjustment of the pressing process. It also replaces conventional valve and control technology. In addition, the drive with intelligent control system can reduce energy consumption by up to 60%, or as much as 80% in combination with the CSH cushion die drive, by controlling the servo pumps and exploiting energy recovery. Because the drives are coordinated with one another productivity is significantly increased.
Self-contained servo drives from Voith are distinguished by their high energy efficiency, overload protection and virtually wear-free operation. The self-contained CLDP servo drive combines hydraulics with a servoelectric system. The drive is extremely compact and highly dynamic and facilitates significant productivity increases for both mechanical engineering companies and operators of the systems and machinery. In addition, the drive offers outstanding features like very high energy efficiency, force and position controls, long service life and virtually wearfree operation. The CLDP servo drive is generally used in applications such as presses, test rigs, cutting and forming machines and other specialpurpose machines that necessitate dynamic response, repeatability and reliability.
Newly developed Eden calculation tool improves efficiency
Voith's innovative Eden calculation tool offers its customers a convenient option for configuring self-contained CLDP drives in advance. A large number of parameters can be changed in advance so that the ideal drive mode can be selected simply and efficiently. This results in faster communication between the project partners and lowers the costs of resources significantly.
The SFM 20 service and flushing module has been specially developed for oil maintenance in Voith's self-contained servo drives. The mobile, portable unit is designed for a canister size of 20 liters and allows trouble-free maintenance with the self-contained servo drives still running. This is achieved by using quick-release couplings to connect the service and flushing module to the drive, so that the used oil in the drive can be replaced with fresh oil in next to no time. An integrated filter unit ensures the necessary oil quality. The simple, logical and safe mode of operation of the SFM 20 service and flushing module guarantees a high degree of servicing quality with a low error rate.
