MORDAZAS DE ALTA PRESION
The
accessories are included :
- Set of 4-clamps.
- Set of swarf protection sheets.
- Handle (crank).
A.- Operation of the vice.
The
Turn the handle until the movable jaw reaches the workpiece. When the jaw touches the workpiece,
E
continue turning the handle. A slight "treshold" pressure will be experienced as the clutch operates,
the high pressure clamping will take place as the handle is turned further. Once the movement
is completed do not continue turning the handle as it could damage the vice.
On the end of the spindle is marked and numbered the tons produced when the handle is turned.
To undo the workpiece move the handle anti-clockwise.
The vice has the pressure intensifier assembly. This assembly is fixed through 2 allen-set-screws,
one at each side of the vice head .
The high pressure hydra spindle comprises 2 independent assemblies :
B.- Cleaning/Maintenance.
Because of the industrial working conditions, on machines and in machining centres in which the
vices must work (swarf, pressure, coolants, etc.), full cleaning of the operational area of the vices
must be assessed as required by the workshop management.
To dismantle the parts for cleaning firstly undo the movable jaw for it, remove the screw on its
rear face. Now raise and lift the movable jaw. Take care not to mislay the half-ball that is inside
the movable jaw.
Loose the 4 screws of the end clamp and the 2 side screws of the vice head. The spindle is loose
and it can be taken out at the rear with the spindle shoe. Now the vice is free for its cleaning. Oil
the parts and carefully replace the parts in the reverse order. Operate the vice "open and close"
a few times to ensure it is free, before loading with workpieces.
For a good maintenance, please use good quality coolants and antioxidizing agents.
C.- Instructions for disassembling the spindle from the vice.
1. Dismantle the movable jaw as explained above on item B (cleaning).
2. Loosen the four end clamp screws and the 2 allen set screws on the head of the vice. Remove
the whole assembly "spindle-spindle shoe". The end clamp comes out easily.
3. For removing the spindle shoe take it towards the hydraulic cylinder.
As above, the hydraulic unit (threaded spindle) must be detached from the clutch unit. For
ease dismantling, at the coupling of both units, the threaded spindle has some flats. Unscrew
the screw (No. 202), holding up the threaded spindle unscrew the clutch unit.
Take out the spindle shoe.
