Crossbar transfer presses/ Compact crossbar presses

Content
Ford SLS Compact Crosspress

(Compact-) Crossbar transfer presses are designed for flexible large-scale series production. Every forming stage has its own transfer module, so that a phase-shifted motion sequence is possible. Unlike standard vacuum transfer presses, with the compact vacuum transfer presses the press intervals are markedly less, so that direct parts transport is possible without necessitating intermediate storage.

 
 

Requirements of components/systems:

  • Hydraulics for controlling assemblies such as e.g. clutches/brakes and die cushions
  • As a rule controlled axes in order to attain the required precision and speed
  • Simple standard power units for tensioning and clamping functions
  • High-dynamic and accurate servo motors for the press transfer
  • Pneumatic components for safe parts transport
  • Central press main drive via longitudinal shaft for all slides
  • Short tool change times thanks to swift adapting of the functions to the part being produced
  • Selectable motion sequences go easy on the mechanics – high dynamic or gentle movement 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 movements of every modular transfer module thanks to freely-programmable motion curves

Efficient production with increased speeds thanks to the system solution with motion control and servo drives
