DÜSSELDORF, GERMANY — Bosch Rexroth AG (Hall 10/C22) is showing components aimed at the hundreds of machinery companies exhibiting at K 2013.

Rexroth is introducing Syrtonix SVP 7010, a family of variable-speed pumps for injection molding machines.

The pumps have a complete selection of hydraulics-specific functions, which used to be handled with valves. Now software of the servo-drive controls things.

The control suppresses "overshoots" when pressure builds up. Integrated vibration dampening makes hydraulic cylinders totally jerk-free, Rexroth officials said. And automatic pulse compensation prevents pressure pulsation on gear pumps.

Rexroth said these controls are pre-programmed, which reduces the engineering effort for machinery manufacturers.

The SVP 7101 also cuts energy requirements by using energy regeneration from braking, then feeds the power back to the machine when needed.

That means Rexroth reduces energy consumption up to 80 percent, compared to fixed-speed drives.

The German mechanical components giant also is showing K visitors its simulation program for the Sytronix. It is based on tens of thousands of applications with actual drives, said Dirk Herold, head of branch management for plastics processing machines at Rexroth.

And the company has expanded the sizes of its ball-screw assemblies for injection molding machines, to fit larger screws, with diameters up to 75 millimeters.

Herold, in an address to the industry in its K show news release, said open architecture is very important for equipment components.

"Rexroth stands for technical neutrality and the free combinability of hydraulic and electric drive solutions," he said.

The trend is for machinery designers to freely combine electromechanical, hydraulic or hybrid drives in one machine.

The technical name is autarkic axes of motion. This eliminates the separation between those differing types of drives, since they are equipped with their own, minimal oil circuit, so they do not need to be connected to a separate hydraulic power unit.

The small- and medium-range autarkic machines are powered by electromechanical lifting cylinders with precision ball screws.
