The New Oilgear "Towler" Energy Efficient Forging Control System will Save you Money
With our specially designed “ACR” Forging System, you only consume power on approximately 60% of your forging passes. Energy (power) from the forging (down) stroke is stored in the ACR drive and then discharged into the return cylinders for the return (up) stroke to save costs.
In order to save energy (power) and costs during forging, Oilgear has designed a high speed, energy efficient, green forging drive, which utilizes energy (power) from the forging (down) stroke to facilitate press return. The system accomplishes this by storing energy into the ACR system during each downward motion of the press and then releasing the stored power via our sophisticated Fast Forge and ACR control system. This specially designed forging press drive not only saves power consumption ($$), it also enables us to achieve very high speed stroking rates, with high forging accuracies (+/- 0.5mm), which in turn:
- Reduce the amount of on-die forging time, which in turn reduces the required number of re-heats.
- Reduce the amount of finishing / machining work required on the forging, thus allowing further cost savings to be realized.
An example of the energy savings would be approximately 215kW per each return stroke on a typical 3500T push-down press with a weight of parts tonnage of 86 tonnes and having an air loaded prefilling tank. Pull-Down (inverted presses) will achieve even higher energy savings as the required force to lift the press is higher than that of push-down presses.
