The feed unit (10) comprises: a first pair of motor-driven lower rollers (12a, 12b) for moving first tubes (T1) forward along a first feed axis (x1); a second pair of motor-driven lower rollers (14a, 14b) for moving second tubes (T2) forward along a second feed axis (x2) parallel to the first one; a first pair of upper rollers (16a, 16b) for urging the first tubes (T1) against the first pair of lower rollers (12a, 12b); a second pair of upper rollers (18a, 18b) for urging the second tubes (T2) against the second pair of lower rollers (14a, 14b); a plurality of first side rollers (22) for retaining laterally the first tubes (T1); and a plurality of second side rollers (24) for retaining laterally the second tubes (T2). The upstream rollers (12a, 14a) of the first pair of lower rollers (12a, 12b) and of the second pair of lower rollers (14a, 14b) are rotatably mounted about a first transverse axis of rotation (y a ) inclined by an angle (±) to the horizontal. The downstream rollers (12b, 14b) of the first pair of lower rollers (12a, 12b) and of the second pair of lower rollers (14a, 14b) are rotatably mounted about a second transverse axis of rotation (y b ) parallel to the first one. The upstream rollers (16a, 18a) of the first pair of upper rollers (16a, 16b) and of the second pair of upper rollers (18a, 18b) are rotatably mounted about a third transverse axis of rotation (y' a ) parallel to the first one. The downstream rollers (16b, 18b) of the first pair of upper rollers (16a, 16b) and of the second pair of upper rollers (18a, 18b) are rotatably mounted about a fourth transverse axis of rotation (y' b ) parallel to the first one. Each upper roller (16a, 16b, 18a, 18b) is adapted to be moved towards a respective lower roller (12a, 12b, 14a, 14b) to clamp a respective tube (T1, T2) against the lower roller (12a, 12b, 14a, 14b). The feed unit (10) further comprises a separating element (34) movable between a rest position, in which it is not interposed between the first and second tubes (T1, T2), whereby the first and second tubes (T1, T2) are in contact with each other, and a working position, in which it is interposed between the first and second tubes (T1, T2) thus preventing these tubes from being in contact with each other.

A micro-machining system (6) configured for cutting an elongate object (8), including a clamp (52) configured to enable repeatedly releasing and then holding the elongate object in a position suitable for cutting the elongate object (8) transversely relative to its lengthwise axis, and a manipulating means, which can include a pinch roller feed (54) configured to advance the elongate element (8) and to rotate it about a lengthwise axis of the elongate object, thereby moving the elongate object (8) so that it can be disposed in the position suitable for cutting, and a cutter (36) configured for forming the at least one precision cut in the elongate object (18) to a desired depth, under the control of a controller (80).
摘要:
A mobile saw bench (10) is designed for cutting elongate workpieces such as elongate open or closed steel sections. The mobile saw bench (10) comprises a base structure (14) which is mounted on four castor wheels (16). Formed continuous with the base structure (14) is an intervening frame structure (18) to which a benchtop (20) is mounted. The saw (12) is appropriately mounted to the benchtop (20) to permit cutting of a workpiece which is located thereon. Importantly, the mobile saw bench (10) further comprises a universal coupling (22). The universal coupling (22) is mounted to an underside of the benchtop (20) and is releasably clamped to an elongate member (24) which is in the form of a rigid measuring staff. The universal coupling (22) allows pivotal movement of the benchtop (20) relative to the measuring staff (24) which is stationary.
