Transfer and multiple-die presses
Mechanical transfer and multiple-die presses consisting of belt conveyor systems or metal blank loaders, presses with tool and transfer, are designed as single or multi-guide systems in accordance with requirements. Articulated lever drives or eccentric drives are used for the drive system.
Requirements of components/ systems:
- Hydraulics for the control of assemblies such as e.g. clutch/brake and die cushion
- As a rule closed-loop controlled axes for attaining the required precision and speed
- Simple standard power units for tensioning and clamping functions
- High dynamic and precision servo motors for press transfer
- Pneumatic components for secure parts transport
- Central press main drive via longitudinal shaft for all slides
- Short tool-changing times thanks to swift adaptation of the motion functions to the current piece being produced
- Selectable motion sequences go easy on the mechanics – high-dynamic or gentle motion depending on the part and the tool being used
Rexroth solutions:
Press main drives in scalable power stages up to 630 kW
Optimization of transfer motions of each modular transfer module thanks to freely-programmable motion curves
Efficient production at higher speeds thanks to the system solution using motion control and servo drives
Modular die cushion: co-ordinated and high-precision system for secure handling of the deep-drawing process (MAC8 for the control, WRC valves)
Solutions for secure control of the clutch-brake combination
Hydraulic overload protection (S-Module)
Hydraulic die cushions
Pneumatic slide cushion
High-precision Profiled rail systems for the slide guide
Ball rail systems and ball screw assemblies for the positioning device
Pneumatic components are to be found in the Pneumatics Catalog
