Screw-in tensioner - Import export

The functioning principle make the wedge clamps ideal for series clamping. The wedge form can exert high clamping forces. These wedge clamps can be mounted in grid holes or T-slots. Tightening the socket screw moves the wedge down and the jaws out pressing the workpieces against the fixtures fixed stops. The wedge has a slightly elongated hole allowing for movement to compensate for tolerances. Spread width: M8 = ±0.5 mm M10 = ±1.0 mm M12 = ±1.0 mm M16 = ±1.5 mm Drawing reference: D) DIN 6912 cap screw 1) Jaw face smooth 2) Jaw face serrated 3) Wedge clamps 4) Workpiece 5) Fixed stop

Fasten the floating clamp to the fixture with the M12 screw. Adjust the height stop and the swivel range using the blue sleeve and lock with the 3x2.5 mm grub screws. When setting the height leave generous clearance above. For safe operation the M12 tapped hole must always be closed. For specific clamping applications the standard jaws can be altered or replaced. Form B: Fasten the floating clamp with M6 fastening holes to a fixture. Adjust the height stop and pivot range using the blue adjusting sleeve and clamp with grub screws (4x AF 2.5). When setting the height limit, allow ample play at the top. For specific clamping situations, the standard jaw plates can be modified or replaced.

The pneumatic hold-down clamp is suitable for clamping workpieces from above. This clamp is operated with standard pressure compressed air. The large swivel angle of the clamping arm makes it easy to insert and remove the workpieces without any obstructions, guaranteeing optimum accessibility to the workpiece. The block design of the housing offers universal fastening possibilities, which means that the clamp can be optimally adapted to the workpiece being clamped. Self-aligning pads with a smooth or serrated faces can be fitted in the clamping arm, enabling rough or machined workpieces to be clamped. These pneumatic clamps can be placed in multiple positions on the workpiece and operated in any particular order. They can be controlled manually or automatically. As these clamps are pneumatically actuated, they relieve the operator, particularly where frequent clamping processes are carried out.

Housing and arm carbon steel. Jaw tool steel. Version: Housing, black oxidised. Arm and jaw tempered and black oxidised.

Tightening the ball-end thrust screw moves the jaw plates forwards. The workpiece is pushed against the fixed stop and simultaneously forced down onto the seating face. The seating face for the workpiece can be mounted directly on the machine table.

We recommend using a lubricating paste to reduce wear to the adjustment screw. Risers are available to increase the height of the power clamp. Supplied with clamping element, support element, DIN 508 slot key and grade 12.9 bolt. Application: The height of the clamping arm can be infinitely adjusted using the adjustment screw and the workpiece can then be clamped. Advantages: Very high retaining forces of 22–49 kN. Low height. Simple element assembly. Enables very fast, simple clamping. Infinitely adjustable height and length. Use in 12-28 mm T-slots or M10, M12, M16, M20 grid systems. Thrust pad available in smooth and serrated versions.
