Secured full flexibility

1,200 metric ton capacity had been the biggest investment that is at body Wagner (KBW) in Bavaria Rohrbach. With 2,500 tons of press force is more than twice as strong machine is now been added: a hydraulic tryout press by Schuler, with the KBW now can shape not only significantly larger parts, but at the same time also ensures full flexibility.
KBW produces prototype parts for VW, Audi, BMW, Daimler, Brose, Faurecia and other automotive manufacturers and suppliers. This means that small lot sizes and still immature tools. Hydraulic tryout presses are ideal for these cases, because the operator can program the required speeds and powers and thereby at any time has the full press capacity available. In addition, facilitated the incorporation of different tools and also benefit the automotive manufacturers who incorporate to the press of KBW their tools or small-batch production of these benefits.
With an area of ??5,000 to 2,500 mm, the clamping of Schuler line is once again considerably larger than the 1,200-ton press manufacturer Müller Weingarten, which is also part Schuler today. The investment was part of a plant expansion of KBW, which includes a new hall and a further machine tool.
The Schuler press is equipped with a so-called dynamic stage circuit (DTC). This means that the ram cylinders are switched on and off via the press control system to increase the operating speed. A special servo-hydraulic control for managing the entire oil flow of the main pump to the required cylindrical surfaces, thus ensuring an optimal utilization of the main drives. In this way, higher working speeds with lower power ratings can be achieved.
Thanks "Efficient Hydraulic Forming" (EHF), the energy demand of the system is reduced automatically in all operating phases. Through a standby function, the unneeded main drives are switched off as soon as the forming process no energy is required. A patented starting system bypassing the usual start-up characteristics of drives and so uses even the shortest period of time without loss of time. And the intelligent variable speed drive provides the secondary functions if and energy when it is needed. Thus, the no-load losses are effectively minimized.
