Segment forming machine SF25-Compact

The segment forming machine SF25-compact is used for the pressing of rotationally symmetric components (pipes, sleeves, shells) without pinch points, which can be inserted into the machine vertically from the top or from the bottom between the jaws. Main area of use: semi or complete automatic units, e.g. workpiece carrier with lift-in assembly, robot controlled assembly or pick-and-place machines.

  • Ø 3 – Ø 25 mm compressible
  • up to Ø 1 mm wall thickness machinable
  • repeat accuracy 0.05 mm
  • moulding cycle approx.. 3-8 sec.

Machine setup

A typical example is the implementation of sensor sleeves which mechanically protect connection leads from being pulled out and seal them at the same time. This procedure also allows crimping of plugs into sensor sleeves. Wall thicknesses of up to 1.0 mm with a diameter of 3 – 25 mm are possible.

The handling of the machine is very simple. The work piece is inserted into the opening, usually positioned with the help of a stopper, which assures that it does not move while the jaws move axially towards the work piece. The corresponding working parameters can be stored and managed in the machine control system. The user interface allows easy and logical operation. All essential processes are electronically monitored and the data is stored in the control system.

However this can also be done by a superordinate system control.

This ensures high process safety and reproducibility.

Other applications in the fields of cutting, chipless isolation, calibration and scoring are also possible.

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) gear belt ratio + ball roller spindle with screw nut for infeed of compression lever system to transmit power to connecting member with tools
  • setup (consisting of connecting member, lever and jaw guide conduct) available in 2 versions:
    • option 1 – narrow model setup designed for pressing of standard components (wall thickness ≤ 1mm)
    • option 2 – reinforced modelsetup designed for pressing of thick-walled components (wall thickness ≥ 1mm)
  • 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 (when used as single machine)

  • 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 guaranteed
  • front protection also available with light grid
  • emergency stop immediately stops all movements


Control system

  • VIPA Speed7 SPS with user panel Siemens TP700 comfort; S7 and TIA portal V13
  • parameterisation and user software installed
  • control cabinet installed into frame

Optional components – additions

The standard SegmentFormer SF25Compact 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.

  • data set is selected, machine in automatic mode
  • forming jaws are open
  • stopper is set in position manually, position has to be set for each data set
  • cable and shell are joined by workman (pre-assembly)
  • component part has to be inserted and held manually
  • component position at stopper is registered by a sensor
  • machine is started automatically or via additional pedal switch
  • forming jaws move to required position and open
  • 1 press position possible
  • component part can be taken out of machine
  • moulding time depending on diameter 2-4 sec.
  • machine can be used for large quantities with little model variance and minor pre-assembly

Load-displacement monitoring

  • load cell in toggle lever calculates load in lever
  • graphic display of loads on separate measuring device
  • OK and NOK evaluation
