Hydraulic Clamp

Hydraulic clamps are one of the most powerful hydraulic tools designed for effective power workholding. A clamp is a device used to join, grip, support, or compress mechanical or structural parts. Its opposing and often adjustable parts provide for bracing objects or holding them together. The hydraulic clamps ensure a powerful and consistent clamping force and enable components to be loaded and unloaded simply and quickly at the press of a button.

Hydraulic Clamps Functions

A cost-efficient tool, the clamp offers effective power workholding due to the distinct designing. It may have a clamping arm that allows complicated jobs to be clamped with a powerful force. To ensure optimum productivity and reliability of the machine, the hydraulic clamp is an ideal choice for construction of pipe-lines and fabrication of pipe-spools in workshops. It can also be set up to push or pull with a threaded or unthreaded center hole. Its low weight and the unique construction of the makes for the welding of complete circumference of the pipes in one operation. The simple and sturdy designs of the hydraulic clamps yield long life. They are ideal for punching and assembly operations or for transmitting force to a remote location via a rod. They are tough, functional clamps that deliver high forces with push or pull action.

The three basic functions of hydraulic clamps are:

• Position the component accurately.
• Support the component adequately.
• Clamp the component securely for machining.

Types of Hydraulic Clamps

Swing Hydraulic Clamps: Swing hydraulic clamps are used to provide maximum reach and clearance for loading and unloading. They have a rotating arm which swings over workpieces to clamp, then swings out of the way using hydraulic mechanism.

Edge Hydraulic Clamps: Using hydraulic technology, the edge clamps apply force forward and down when clamping from above.

Push Hydraulic Clamps:Push clamps deliver high locating forces in a compact design which lets close positioning of multiple units.

Block Hydraulic Clamps:Block hydraulic clamps are ideal for punching and assembly operations. They are functional clamps which deliver high forces with push or pull action.

Extending Hydraulic Clamps: Extending hydraulic clamps are considered the most compact downholding clamps available. They are used for clamping in narrow recesses, their arm moves forward, then straight down to clamp.

Flat Pivot Clamps: Flat clamps as the name suggest are designed for clamping flat workpieces on machine tools and for welding applications.

Hydraulic Clamping Technology: Advantages

Hydraulic Clamping technology has some advantages over other varieties of clamps:

• The main benefit is that hydraulic clamping reduces downtime thereby increasing productivity and maximising capacity utilization.
• Hydraulic positioning and clamping is an extremely reliable and efficient technique.
• The major advantage of hydraulic clamping is the enormous time saved in clamping and unclamping the components.
• There is precise positioning and clamping using hydraulic clamps.
• Another great advantage is that it makes optimum use of clamping space because of compact standard components. It also can clamp in manually inaccessible areas. As a result the number of components to be clamped can be increased and processed simultaneously on one fixture.

What to look for in hydraulic clamps: Selection tips

• The clamping stroke and force of the hydraulic cylinders
• The power source
• The control of the clamping system (valves and other accessories)
