Abstract
A sawing device includes a wire assembly (15) supported on wire-guiding rolls (11, 12) and pressed against a workpiece to be sawn (20) fixed on a support table (21). An oscillating device (23) produces a relative reciprocating movement between the workpiece and the wire assembly (15) around an oscillation axis (A) whereof the spatial position can be adjusted and programmed so that the oscillation axis (A) is at a programmable and adjustable distance from an effective axis of rotation (28) of the oscillating device (23).
Claims8
Wire sawing device comprising:
- at least one layer of wires (15) movable with alternating or continuous movement;
- wire guide cylinders (11, 12) supporting and pressing the layer of wires against a piece (20) to be sawed;
- an advancing means (19) providing a relative advancing movement between piece (20) to be sawed and the layer of wires (15) in a cutting direction (Z) contained in a cutting plane (YZ);
- an oscillatory means (23) providing a relative oscillatory movement between the piece (20) to be sawed and the layer of wires (15) about an axis of oscillation perpendicular to the cutting plane,
- the oscillatory means comprising an oscillation device (23) having at least one effective axis (28) of rotation and movable members (24, 30) arranged so as to produce a relative movement of oscillation between the piece (20) to be sawed and the layer of wires (15) about an axis (A) of oscillation with a spatial position that can be adjusted and programmed such that the axis (A) of oscillation is located at a programmable and adjustable distance (Z) from the effective axis (28) of rotation;
- and
- at least one support table (21) on which the piece (20) to be sawed is fixed,
- the oscillation device (23) arranged to act on the support table (21),
- the oscillation device (23) comprising at least a first rotatable member (27) to carry out a rotation (α) about the effective axis (28) of rotation perpendicular to the cutting plane (YZ),
- the movable members of the oscillatory means comprising a second member (30), carrying out a movement in a direction parallel to the cutting plane (YZ), and a third member (24) carrying out a translatory movement in a direction coinciding with the cutting direction (Z),
- the rotatable element (27) mounted on the third member (24), and
- the second member (30) having a sliding element (31, 32) disposed between the rotatable element (27) and the support table (21) on which the piece (20) to be sawed is fixed.
