Description

Specifications

  • Maximum unit operating pressure – 250 psi air, 2000 psi hydraulic (17 bar air, 137 bar hydraulic)
  • Draw tube force – 5.8 x line pressure
  • Collet capacity – 16C {1/64" to 15/8" (.39 to 41.27mm) round}
  • Thru-hole in base
  • Four 1/4-20 mounting holes in bottom of base
  • Two 3/8" (9.52mm) dowel holes in bottom of base
  • Two 1/4"-18NPT ports
  • 2-position, 4-way control valve recommended for hydraulic operation, 2-position, 3-way control valve recommended for pneumatic operation (not included)

Safety

  • Do not over tighten the mounting hardware or the plumbing fittings.
  • When installing a collet in the closer, do not over tighten the collet.
  • Do not exceed maximum operating pressure of 250psi air or 1207 psi hydraulic (17 bar air, 83 bar hydraulic).
  • Make sure that the collet retains your material when the closer is closed.

Application

This 16C collet block is a stationary unit with a double-acting cylinder. It is effective on machine and assembly operations that require reliable clamping and unclamping. Use the collet block as a single unit or mount multiple closers on rotary tables, pallets, fixtures or tombstones for increased productivity.

Installation

1. Mount the collet block to a rigid flat surface.

2. Plumb your first supply line using 5000 psi (344 bar) rated steel tubing to the CLAMP 1/4 NPTF port of the collet block and the normally OPEN 1/4 NPTF port of your control valve.

3. Plumb your second supply line using 5000 psi (344 bar) rated steel tubing to the UNCLAMP 1/4 NPTF port of the collet block and the normally CLOSED 1/4 NPTF port of your control valve.

4. Plumb your control supply to the 1/4 NPTF pressure port of the valve.

5. This configuration maintains a closed collet until the valve is actuated.

Operation

1. Remove the supply from the valve.

2. Loosen the collet locking screw.

3. Insert the collet in the top of the collet block.

4. Using the collet wrench, turn the collet clockwise until it contacts the piston taper.

5. Tighten the collet locking screw. Do not overtighten.

6. To close the collet closer, insert a workpiece in the collet, and connect the supply to the control valve. WARNING: Do not close the closer without the workpiece in the collet.

7. Adjust your supply pressure to a level that assures effective workholding only. Continuously operating the closer at maximum pressure will decrease the service life of the seals and collet. WARNING: Pressure to this closer above 250 psi air or 1207 psi hydraulic (17 bar air, 83 bar hydrualic) may overstress the 5C collet.

8. To open the collet, actuate the valve.

Maintenance

If, over a period of time, you experience a decrease in clamping force even though pneumatic or hydraulic pressure remains unchanged, remove the collet block from service, disassemble, and replace any damaged or worn o-rings.
