Return to product index.	Request catalog for complete technical data.	Review next product.

Single-Acting Wedge Clamps clamp mechanically by spring and unclamp with hydraulic pressure for quick clamping of dies and tools. The self-locking clamps consist of a housing with two-piece clamping bolt and flange-mounted block cylinder. In retracted position, the wedge clamping bolt retracts in the housing. Single-acting unit delivers 2,800 lbs. clamping force and 11,250 lbs. retention force.

Advantages:

• Clamp without hydraulics.
• Clean, compact design.
• Self-locking.

Wedge Clamping Bars are custom designed according to customer requirements to simplify the use of multiple, side-by-side clamping elements. With their integrated clamping bolts and block cylinders, these bars can also serve as stops or supporting ledges. Hydraulic fluid for operating the block cylinders can be supplied through drilled passages in the fixture plate and clamping bar for a work area free of hoses or pipes. Bar units are available in many configurations, with typical clamping force per element up to 57,000 lbs. Contact HILMA for further information.

Advantages:

• High power density.
• Flexible location of drill holes allows easy installation.
• Drilled passages keep hydraulic lines out of the way.
• Available for use on tools with straight or tapered clamping edges.

Traveling Clamps

Traveling Clamps provide automatic upper die clamping on large metal stamping presses. The clamps quickly accommodate dies of different shoe widths, and are specially suited to automotive stampers, as new or retrofit systems. Compact traveling clamps feature an electric motor-driven chain which moves the hydraulic clamp against the die. The chain drive is completely retracted from the T slot when the clamps are in the home position.

The clamps are available as single- or double-acting units. The double-acting version provides fast unclamping and added safety via a pilot-operated check valve built into each clamp. Order traveling clamps with clamping forces of 22,000 lbs. at 2900 psi, or models with 37,000 or 57,000 lbs. at 5800 psi. Clamp stroke ranges to .866" for wider variation of clamp height. Various configurations are available to suit specific customer needs.

Advantages:

• Save the cost and weight of extra die plates.
• Quickly clamp dies of varied sizes.
• Great for use in automotive stamping.
