Overview: Hirth Couplings

Serrated Locking Plates

Serrated Locking Plates do not offer the high precision of Hirth couplings, but offer a cost-effective solution for positioning applications. The range of designs makes these plates adaptable for almost any application. To complement these serrated locking plates, accessories such as guide pots GN 187.1 and thrust springs GN 187.2 are useful additional standard parts. Contact us for further information.

Hydro-mechanical Self-locking Transfer Rail Couplings

The hydromechanical self-locking gripper rail coupling is designed for automatic coupling of gripper rails on transfer presses. A vertical lift-out stroke is required for changing the tool. The coupling consists of a hard anodized aluminum housing, an axially movable tensioning rod and a hydromechanical self-locking clamping gearing. This configuration allows for high clamping forces and features a very high dynamic rigidity with minimum mass.

Electromechanical Transfer Rail Couplings

The electro-mechanical gripper rail coupling is designed for automatic coupling of gripper rails on transfer presses. A vertical lift-out stroke is required for changing the tool. The coupling consists of a hard anodized aluminum housing, an axially movable tensioning rod and an electromechanical self-locking helical gearing. This configuration achieves a very high repeat precision, high clamping forces, and features dynamic rigidity with low mass.

Manually Operated Eccentric Cam Style Transfer Rail Couplings

The mechanical self-locking gripper rail coupling is designed for manual coupling of gripper rails on transfer presses. A vertical life-out stroke is required for changing the tool. The coupling consists of a hard anodized aluminum housing, an axially movable tensioning rod and a self-locking eccentric cam gearing. This configuration allows high clamping forces and features a high dynamic rigidity with minimum mass.

Overview: Clamping Systems with AS-Interface

The BERG AS-Interface clamping and chucking systems are intended for clamping various tools/dies on press slides and black holders, and for sliding table clamping and gripper rail couplings on multiple die presses. They are used on new machines and for retrofitting automatic clamping systems in existing press lines.

Manually Operated Swing-out Style Transfer Rail Couplings

The mechanical self-locking swing-out style gripper rail coupling is designed for manual coupling of gripper rails on transfer presses. A short lift-out stroke is required for changing the tool. An axial stroke is required in the event of additional centering with pins. The coupling consists of a hard anodized aluminum housing, a swiveling tensioning rod and a self-locking eccentric cam gearing. This configuration allows high clamping forces and features a high dynamic rigidity with minimum mass.
