CABLE SHEATHS - Amuflex
Machine Tools Support
Flexible sheath Amuflex allows conducting tubes (electric, hydraulic or pneumatic) to moving terminals.
The function of the steel leaf for springs is to provide the tube’s spires of a pre-charge of self-supporting. Furthermore it assures the tubes’ integrity.
The connection between spiral tube, steel leaf for springs and the flange is mechanically realized with rivets. Plus, the two steel leaf ends are folded over the external side of the tube and then engaged into the flanges.
Unlike the system with external leaf attached, this system doesn’t undergo the action of fluids and powders that first or then causes, combined with the spire’s solicitation, the leaf’s detachment.
In order to define Amuflex Sheath’s overall dimensions it is necessary to determine five conditions:
- section (NG)
- radius of curvature (R)
- total length
- flange’s model
- flange’s orientation
If required, it is possible to provide cable cases with rubber gasket between the spirals (production model SV310S). Sheath’s size is defined according to the cables’ number and diameter.
Usually inside every sheath is placed only one cables’ layer. In case of a limited number of operations it is possible to place the cables in more than one layer. Radius of curvature is determined as each case requires, but it would have to be more or less 10 times the electric cable or flexible tube to transport.
That’s why it is necessary to analyse data from the cables or tube’s producer. The higher is the strokes’ number, the larger must be the radius of curvature. The radius R recommended in the order is the medium radius of curvature of the tube. The following is the formula to define AMUFLEX cable case sheath’s total length:
(0,5 x path) + (3,14 x R) + (2 x 0,5 x R)
Sheath’s development length fits the sheath’s length in its working position. The working rotation radius of the spires, while processing, corresponds to the internal radius. So the sheath, in a straight position, is shorter for a multiple of Z, as explained in the table for the determination of length quota A. .
