Modification – Clutch/brake combination for AMP 20 and AMP 20 S models

As part of developing the AMP 20 to the AMP 20 N models, the flywheel shaft compound, among others, was analyzed in more detail. The assembly was fundamentally redesigned, not only because of various technical requirements but also due to difficulties in procuring the clutch and the brake.

In particular, the flywheel shaft bearing, the clutch and the brake needed to be redesigned completely. The reworked assembly was incorporated into the latest version of the AMP 20 S and can now be offered for all existing AMP 20 and AMP 20 S models as a modification and upgrade.


Previous design of the flywheel shaft compound

In the previous design, the clutch and the brake were physically separated from each other. The compound was controlled via a 3/2 directional control valve and the flywheel was mounted indirectly on the flywheel shaft.
 

New design of the flywheel shaft compound

A new clutch/brake combination is fitted, where the clutch and brake are housed in a single unit. The flywheel is stored directly on the bearing block and is controlled via a press safety valve. This immediately provides several advantages.
 

The advantages

  • State-of-the-art modern clutch/brake combination.
  • The flywheel turns on the bearing housing, rather than on the pinion shaft, which is unburdened as a result.
  • Significantly lower maintenance costs as only the friction pads are used as wearing tools.
  • The friction pads are quick and easy to replace.
  • By removing the brake, there is improved access at the rear of and  under the pressram.
  • The lead times are comparatively very short.
  • The reliability of supply is ensured.

All AMP 20 model customers will benefit from this modification. Depending on the load and switching rate, the investment will pay for itself in only three years. The AMP 30 is already being checked so that this model can also have the many advantages in the near future, if applicable.

Lubrication Oil Reimagined - ORS by Hatebur

Rising oil prices, increasing cost pressures, and stricter sustainability requirements are presenting new challenges for metal forming technology. But what if up to 90% of the lubricating oil used could be reused? With Hatebur’s ORS (Oil Regeneration System), used oil is transformed back into a valuable resource—efficiently, economically, and sustainably.

More efficient cold forming thanks to the servo infeed

A servo motor infeed combines technical with major economic advantages. We have offered this feature as a retrofit for hotformers for a long time. This option is now also available for our coldformers. To do so, the Hatebur team is building on over 20 years’ experience in developing, designing and integrating servo motor components.
