Metalformers have a wide variety of hydraulic clamps from which to choose, including ledge clamps (top), which can be placed manually in T-slots or bolted to the bolster or slide, and clamp directly on a flat clamping surface; and rod clamps (bottom), which mount in T-slots on the bolster or slide and U-slot cutouts on the clamping surface.
• Roto-Escam clamps hide beneath the press bed or inside the slide. The clamping rods rotate 90 deg. and retract below the bolster and slide plate, completely escaping the die area and allowing for clear access when loading and unloading a die. They can clamp in a T-slot or in a special machined hole.
• Swing clamps release the die by tilting 30 deg. to one side, and must have U-slot cutouts in the clamping surface.
• Traveling clamps use a driven chain mechanism or an air cylinder to auto- matically travel down a T-slot to reach the clamping surface.
A final suggestion: For any QDC hardware you purchase now, try to visu- alize how it might affect the future use of your basic pressroom equipment. For instance, consider any plans to add periph- eral equipment such as transfer systems, feed lines and conveyors when deciding what type of QDC hardware to buy and how and where to install it. MF
