Transfer Systems

GPA Transfer Systems run angularly synchronous with the press drive of mechanical presses. With hydraulic presses, we deliver a start-stop inter-link to the press. The Transfer Systems are fully electronic, freely programmable and available in 2 or 3 axes for:

Utilization

GPA Transfer Systems are designed to transport parts stepwise in multi-station die sets. Uses range from traditional sheet metal forming applications to multi-station forging applications. Our use of integrated subassemblies allows the free-range versatility of multiple application modes as well as the trouble-free integration of the press operating cycle. This makes the application of GPA Transfers ideal for retro-fits and new press installations.

Mounting and Integration

GPA Transfer Systems are laid out in relationship to the press bed. The drive housings are mounted to the press columns. When necessary, the Transfer System can be alternately mounted to rolling bolsters or to additionally provided sub-frames. Cut-outs in the press frame for drive shafts are not necessary. The electrical installation is simplified due to almost all components being housed in a single switch cabinet. The panel is linked to the transfer and operator station via integrated multi-pin connectors. With predefined information exchange between the press, the transfer (e.g. slide position, start commands, E-stops, etc.), a trouble free operation is assured. All systems include a modem link for off-site trouble shooting and new part integration.
