HFS - Hydraulic Traveling Clamp

HFS Photo

Area of application

The latest OPTIMA Traveling Mechanisms uses Hollow Piston Cylinder Clamps (HKZ) to automatically clamp varying die widths. This model can be used in standard t-slots and is extremely easy to install. No die modifications are required, clamps fit into existing t-bolt cut-outs. All electrical connections are incorporated into a single quick disconnect plug. This HFS is ideal for new presses as well as retro-fit applications.

Functional Description

The HFS model is driven by an extremely rugged chain design that rides in the t-slot "head" area. This compact and maintenance free drive mechanism allows the clamps to be positioned anywhere along their travel range. Once the clamp reaches the die, its travel is halted by a proximity sensor and the clamp is hydraulically energized thereby securing the die. Clamp forces are continuously monitored via pressure switches in a redundant dual safety circuit. When unclamping, the clamp releases and is automatically retracted to its "home position".

Technical Data

Operating Procedure (SD):

To Clamp

  1. Visually inspect clamp for obvious defects and make sure that the arrow on top of the "activation-nut" is pointing toward the RED dot.
  2. Place clamp into T-slot.
  3. Unscrew clamping screw sufficiently so that clamp jaw easily passes over the die shoe.
  4. Push clamp forward (toward die) as far as possible to ensure proper seating. Make certain that the die shoe surface is free of debris and lubricĀ·ants.
  5. Pre-clamp by hand tightening the clamping screw as far as possible (to pre-torque value) so that solid contact with the die surface has been achieved. Make certain that the unit is not cocked. Tapping the frame of the unit (with fist) while hand-tightening will ensure proper fit.
    Note: Maximum clamping force can be achieved by pre-clamping with a spanner wrench rather than hand-tig hten i ng.
  6. With the use of a hex head wrench turn the "activation nut" 1800 until it reaches its stop and the arrow is pointing toward the GREEN dot.

To Unclamp - Reverse procedure.

Operating Procedure (SD-A):

To Clamp

Due to an internal clutch mechanism preclamping and clamping are both activated by the activation nut. The activation nut is turned with a socket or open end wrench until the indicator line is pointing toward the green dot.

To Unclamp - Reverse procedure
