Hydraulic Turn
Clamp Cylinder
HDSZ
- For medium and large presses
- For clamping upper and lower dies
- For dies with lock plate, U-recess or T-slot
- Fixed installation in press slide or press bed
Mode of operation
- A single-acting hydraulic cylinder with spring return supplies the clamping movement.
- A double-acting hydraulic cylinder provides rotation.
Description
A hydraulic rotation unit turns the tie rod head 90°. Then, the clamping cylinder executes the clamping stroke. The sequence of movements is controlled internally. In order to secure the clamping force, hydraulic pressure must be maintained (e.g. with pilot-controlled check valves).
Pressure monitoring by the pressure switch on the hydraulic power pack is required. To unclamp, the tie rod is lifted off the die by means of a return spring. Rotation occurs via the hydraulic rotation unit.
- Fully automated operation
- Large clamping dimension tolerance
- Simple monitoring of functions by proximity switches
- Minimal installation investment
- Pratically maintenance free
- High clamping force and small dimensions
- Only two hydraulic connections required
- Tie rod can be turned by hand
- Pilot-controlled check valves
- Flow control valves
- Fittings
- Hydraulic hoses / Hydraulic accessories
- Hydraulic power packs
- Limit switches / cable

1* Mechanical damage may occur at higher loads. 2* If a pump with a greater output is used, the oil flow must be reduced by means of flow-control valves or one-way restrictors.
Fixing is achieved with four screws, DIN EN ISO 4762 , strength class 10.9 (not included).
