Mammoth swivel units

The growing acceptance of swivel systems and the pressure toward more flexibility in line layout have driven the demand for high-performance swivel unit drives. Whereas the Tünkers swivel units of the KS and EKS series with maximum torques of 200 – 300 Nm were exclusively designed for the positioning of clamps, welding tongs, cap mills or smaller assemblies, some drawing offices are now setting higher demands. In some individual cases it is requested to swivel in complete gripper systems or even fixtures. Those are operations that used to be reserved for robots.

Obviously, such performance classes cannot be realised sensibly with pneumatic drives. Therefore, with regard to our mammoth swivel unit, we resort to an electrically driven Expert index drive. The integrated curve-driven mechanism safeguards a sinusoidal motion sequence with a soft start-up and harmonic slow-down. The integrated dwell period provides for backlash-free locking of both positions in connection with a conventional three-phase a.c. motor. The entire range of opening angles from 0 – 180° can be chosen from, so that the mammoth swivel unit can also be recommended as a transfer unit from station to station.

On our 2008 symposium we presented the first variant type EKM 500. Following the modular system, further variant types such as EKM 1000 and EKM 2000 with torques of up to 1,000 and 2,000 Nm can be realised in conjunction with Expert drive units.

We would be pleased to provide you with a sample unit for testing purposes free of charge.
