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)

Standard power units

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
