Description

Threaded-body cylinders are directly screwed into a base body.
Hydraulic oil is fed through drilled channels. Thus exposed pipes and fittings are omitted.

Threaded-body cylinders are normally single-acting hydraulic cylinders with spring return.
The incorporated return spring retracts the piston in depressurised mode.
Single-acting threaded-body cylinders with spring return must not be subjected to a load in retracted position.

There are different versions of threaded-body cylinders with standard hydraulic piston and in plunger design.

Special versions:

Application example

Application example 1

Multiple clamping fixture for clamping of small parts. The cylinders can be arranged in clamping bars or yokes.

multiple clamping fixture

Application example 2

This multiple clamping fixture is equipped with threaded-body cylinders with swivel contact bolts. The 3° incline of the threaded-body cylinders effects a low-clamping force of approx. 5 % of the clamping force. On plane clamping surfaces swivel contact bolts obtain little surface pressure on the effective points.

Application example 3

Workholding with the use of reversing levers is particularly suited for workpieces which have to be clamped high above the fixture base plate. The force-loop closed within a limited fixture component space eliminates bending forces from entering the fixture base plate. The reversing lever allows easy adaptation of the lever ratio to the clamping force required.

Application example 4

Double-acting threaded-body cylinders in a multiple clamping bar for a welding fixture. Contact bolt with coupling pin (see data sheet G3.800)

Application example 5

Double-acting threaded-body cylinders as pull-type cylinders for a multiple clamping fixture to mill a wrench flat.

Application example 6: Injection mould

Special feature
Mould a rectangular nozzle with cross hole.

Design solution
Mould rectangular nozzle by inclined mould release trigger (2).
Mould cross hole by mounted threaded-body cylinder (5) in slide (2).

Cycle (portrayed in simplified terms)
1. Mould closed, substance injected
2. Threaded-body cylinder (5) moves out of the mould
3. Mould opens (the slide operates, the nozzle is free)
4. Workpiece will be removed from mould
5. Mould closes
6. Threaded-body cylinder (5) moves into the mould
1. New cycle

Advantage

  • Less movable parts
  • Higher safety of the function sequence
  • Saving of the wearing parts
  • Only one guide
  • Integrated oil supply within the slide

Disadvantage

  • Environmental temperature up to max. 180 °C
  • Cycle time a little bit longer
