DESTACO 858-E Pneumatic Hold Down Toggle Clamp, 4000 lb Holding Capacity

Destaco 858-E pneumatic hold down clamp is actuated by compressed air for quick clamping in the automotive and food & packaging industries. This relieves the strain on the user, particularly where frequent clamping processes are carried out. The air pressure is applied in the clamping port, which thereby moves the clamping arm to hold the workpiece. The required clamping force is achieved and exerted on the workpiece. This pneumatic clamp can be actuated simultaneously or can be closed or opened in a certain order. Destaco 858-E pneumatic hold down clamp has a toggle system that ensures the unit remains closed even if the air supply fails. Moreover, air consumption is low due to the high final transmission ratio. Destaco toggle system offers large opening travel, achieved by the pivoting of the clamping arm, and the optimum force and movement ratios that arise as a result. This pneumatic toggle clamp holds the workpiece firmly and positively. For unlocking the clamp, the air pressure is applied in the unclamping port. It is completely self contained & requires only a pressure source for user safety. Destaco pneumatic toggle clamp is sensor ready for both round and T slot style sensors, and features inbuilt flow restriction to eliminate the need for external flow controls. It allows economical use on short-run jobs with temporary fixturing and is equipped with magnetic piston rings for precise position sensing. Destaco 858-E pneumatic hold down clamp has a large opening angle of 96 degrees that ensures easy component removal.

Frequently Asked Questions:

Q. What are pneumatic toggle clamps?

A. Pneumatic toggle clamps feature the same basic design and operation as manual hold-down or straight-line toggle clamps, but are operated pneumatically. They are completely self-contained and require only a pressure source hook-up.

Q. Which grease is ideal for Destaco clamps for their rebuilding?

A. A coupling grease like Mobil XTC should be used when dealing with Destaco mechanical clamps, while the Magnalube G grease is great for use with pneumatic cylinder seals.

Q. What does holding capacity mean in terms of clamps?

A. The holding capacity or the holding force depicts the clamp's capability to hold down equipment or sheet metal on assembly lines or during similar manufacturing processes.

Q. What is the significance of the red colour of the handle of Destaco clamps?

A. There is no such significance of colour of the clamp's handle, as it only represents a recognisable area. This helps operators in finding the handle quickly & easily.

Q. What does clamping force mean?

A. Clamping force is the amount of force actually applied to a workpiece by closing & locking the clamp. It is normally less than the stated holding capacity. The actual clamping force depends on various factors, including cylinder bore, cylinder area, spindle position (clamping arm length) and available air pressure. In most cases, the clamping force is approximately 2 to 3 times the force exerted by a pneumatic cylinder.

Q. Does Destaco supply any water resistant clamp sensors?

A. Yes, Destaco also supplies inductive sensors designed in accordance with IP65 standards to ensure protection from powerful hydraulic jets, dust & heavy rain.

Q. How much pressure is a toggle clamp capable of?

A. Destaco hold down toggle clamps apply downward clamping force by increasing the applied load via toggle mechanisms. You can see the clamping force on the packaging itself, which is specified in Newton (N). Use this information with the size of the toggle clamp to work out the degree of pressure that the tool will have to exert on a piece of wood. The larger the piece of wood, the greater the pressure required.
