Segment forming machine SF25-open

The segment forming machine SF25–open is used for components with pinch points, which cannot be inserted into other machines, e.g. angle plugs. Suitable for metal pipes with wall thicknesses of up to 1.0 mm and a diameter of 3 – 25 mm.

Machine setup

The operation of the machine is very simple. The workpiece to be shaped is inserted into the machining opening. With this special form of the segment former, it is also possible to insert the workpiece laterally through an insertion slot. As a rule, the workpiece is positioned by means of a stop, it stands still while the mould jaws move axially towards it. The corresponding parameters for machining can be stored and managed in the machine control. The user interface allows simple, logical operation. All key processes are electronically monitored and the data recorded in the control system. This ensures a high level of process reliability and reproducibility.

Basic machine

  • basic module with fastening holes for the reception of all functional components consists of: base panel with carrier for motor with gearing and spindle ball bearing
    • drive system: 1 servomotor + gearing + encoder and motor cable 3/5m (1 CNC axis) ball roller spindle with screw nut for infeed of compression lever system to transmit power to force ring and toggle lever with tools
  • forming head with lateral slot for easy insertion of component part
  • jaws (forming tools) adjusted to client specific final outline
  • flat and circular compression possible; for round compression jaws have to be fitted to a diameter
  • possible number of jaws: 6, 8, 12 or 16
  • closing and opening stroke are steered over relevant curves by a servomotor


Protection measures

  • covering of drive mechanism
  • protective tube at back of forming head prevents reaching inside
  • protective cover at front of forming head; easy insertion of parts guarantees quick assembly
  • front protection also available with light grid
  • emergency stop immediately stops all movements


Control system

  • VIPA Speed7 SPS with user panel Siemens TP700 comfort
  • parameterisation and user software installed
  • control cabinet installed into frame
  • additional buttons for start, stop and emergency stop
  • pedal button for release of forming process by operator
  • data sets selectable via user panel (by means of bar code scanner if desired)



  • data display on user interface
  • calibration instructions are set up and selectable at all times via button
  • standard databank for product specific parameter with 50 data sets (expandable up to 4,000)
  • 3 access levels for machine control (user, service and administrator)
  • language can be chosen as requested (default German and English, other languages with extra charge)



  • holds all machine components
  • standing work station, length x width x depth approx. 1,010 x 1,010 x 890 mm
  • working height approx.. 1,123 mm
  • 4 rotatable wheels, 2 with locking brake
  • welded and coated steel frame, colour can be chosen as requested
  • desk top made of steel or wood

Optional components – additions

The standard SegmentFormer SF25open can be equipped with various optional attachments and functions. This makes it possible, for example, to expand the machine into a semi-automatic press with process monitoring.
