Horizontal flow-forming center

This machine is specially designed for the production of heavy internally toothed clutch and gearbox components using the flow-forming process. Metal rounds, preforms or forged unfinished components of the most diverse grades of material can be used as the feed blanks. The use of an optionally available driven tailstock sleeve also permits production of double-sided clutch and gearbox components. The fixed three-roll flow-forming support and the longitudinally movable main spindle are characteristics of the HDC machine concept. The rotating main spindle is passed for forming of the workpiece through the fixed three-roll flow-forming support. A roller pillow block for mounting of a flow-forming roller is installed on every radial feed unit. Each pillow block is equipped with a hydraulic roll drive system and an axial adjustment system, permitting positioning of the flow-forming rollers at an offset to each other. A central hydraulic ejector and an external stripping unit, also hydraulically activated, permit trouble-free removal of the work.

Features

  • Horizontal type, robust design
  • Main spindle driven by a frequency-controlled three-phase motor
  • CNC-controlled electrically driven ejector in the main spindle
  • CNC-controlled programmable tubular stop – fast changing of chuck jaws thanks to special WF design –
  • precise linear guides on the support assure accuracy of repetition in series production
  • CNC-controlled loading/unloading unit, thus providing good potentials for automation

Benefits

  • Short cycle times
  • High forming forces in the longitudinal and radial directions for production of difficult components
  • Production of double-sided components in a single operation
  • High flexibility thanks to CNC control

Branch

  • Industries
  • Automotive

End products

  • Internally toothed gearbox components
  • Clutches/couplings
