S-Former E

The electric S-Former E comprises a tapping unit, servodrive and PLC unit. This can control up to four tapping units at once and monitor these on an ongoing basis, which ensures top thread quality and 100 % process safety. The S-Former E is therefore suitable for the defect-free production of safety-relevant parts.

The S-Former E can also be operated as an independent production unit.

Impressively flexible and convenient

The S-Former E offers four tapping units for different thread sizes:

S-Former EE0E1E2E3
Ø thread [mm]1-44-88-168-26
Rotation speed [1/min]Up to 5,000Up to 2,500Up to 2,000Up to 1,000

 

  • The tapping units heads are driven by powerful servodrives with up to 2.25 kW (400 V).
  • The high torques and rotation speeds, as well as the steep acceleration curves, enable the number of cycles to reach up to 160 strokes per minute.
  • Generous performance reserves prevent overheating of the motors.

The tap moves pneumatically on the tool within split seconds, the pitch being defined by the tap, which pulls itself into the part. In this way, the forming process is free from axial forces, which maximises the lifetime of the tap. Rotation speed and acceleration are regulated by the control unit and can be freely adjusted as required to match your tools and processes. As the drive of the S-Former E is fully independent from the tool and press, it can be easily removed from one tool and installed in another and is ready to use again in a few simple steps.

Irrespective of size (E0, E1, E2, E3), up to four tapping units can be controlled by a control unit. Up to 50 freely configurable programs can be saved for each tap connection so that the change from one production series to the next can be made without any time delay. The clear, multilingual menu instructions and large 12" touch display display comfortably guides the operator through all relevant menus, offering all important system information prepared in an understandable manner.

Absolute process reliability

In preparation for process monitoring, the torque curve is recorded and averaged in several cycles with an optimal system function using the teach-in process. By manually defining non-critical tolerance ranges, an envelope is calculated and shown graphically on the colour display.

During production, the torque curve is constantly measured and compared with the envelope. After each successful cycle in which the torque curve lies within the envelope, the PLC sends a signal to the press control unit and the next feed begins. However, if it is outside the envelope, the press control unit receives no signal. Production is stopped and the cause of error (e.g. worn tap, incorrect position of the part in the tool, punched hole too large or too small, etc.) can be fixed. This ensures that no part with a defective thread leaves your production. The data can be visualised on the display at any time, including during operation, before being output and further processed as part of process and quality assurance (proof of defect-free production).
