      Drive systems for punching and shearing applications

      Modular in design and providing the highest degree of application flexibility together with safe and simple process control is all made possible with our highly dynamic switching valves. Our punching and shearing hydraulic systems feature compact short-stroke valve cylinders. When special forming processes and positioning tasks are required, proportional and servo control technology are utilized. Furthermore, complete systems are supplied and are easy to connect to the machine. These systems comprise of an actuator, a hydraulic control, a power pack with energy-efficient internal gear pumps and an electronic control.

      Press drive PSH

      Productivity and efficiency play an immensely important role in manufacturing com­panies. This is one reason why servo presses are being used more and more often in forming technology. Voith's innovative PSH press drive gives you a highly flexible drive system that allows you to design your motion se­quence and press force in a precise and highly flexible manner. The power transmission in the PSH is hydraulic. Nevertheless, the system is com­pact and requires considerably less installation space than other drive systems. Furthermore, it operates without conventional valve and control technology. Actively controlled servo pumps generate a volume flow only when needed in the hydraulic system, this re­duces the energy consumption of your press by up to 60 percent.

      Technical data

      Press force 500 to > 10 000 kN (50 to > 1 000 t)
      Functional principle during quick-traverse operation Suction operation with controlled speed
      Logical stroke length > 400 mm
      Position-control precision 0.01 mm
      Pressure-control precision ± 1 bar

      Looking for a press drive with different data? We are sure to have a solution for that one as well.

      Die cushion drive CSH

      Die cushion drive CSH
      In deep drawing presses, two subsystems play the decisive role for productivity and workpiece quality: the press drive and the die cushion. A precisely defined blank holder force ensures controlled flow of the material into the drawing die and is the basis for a stable forming process. The innovative Voith CSH die cushion drive provides you with a highly flexible servo-hydraulic drive system. With this drive, you actively and precisely set the characteristics for position, force and speed – and you can do this over the entire deep drawing process. Your die cushion becomes a servo cushion!

      Application fields

      • Retrofit of hydraulic die cushion drives and control systems
      • Upgrade of mechanical, gas spring supported or hydraulic blank holders
      • Retrofit of servo-electric die cushion drives
      • Deep drawing presses:
        • Hydraulic presses with die cushion
        • Servo presses with die cushion
        • Mechanical presses with die cushion
      • Perfect complement to the Voith PSH servo press drive
      • Defined delay of high-mass bodies

      Accumulator charging units

      Accumulator charging units are the flywheels of hydraulic systems. Their task is to temporarily store hydraulic energy. Using an accumulator charging circuit makes particular sense if the energy demand of a hydraulic system varies greatly. A hydraulic accumulator fills during the partial-load or no-load phases of the machine cycle. The energy stored in this way is then once again available during periods of high energy demand. This makes it possible to design the motors and pumps only for the average energy demand.

      Accumulator charging units
      1 Accumulator charging main block
      2 Check valve
      3 Safety valve (type examination)
      4 Accumulator charging valve
      5 Pressure gauge
      6 Manual accumulator discharging
      7 Optional: electric accumulator discharging
      8 Optional: pressure switch for system pressure
