摘要： A tube bending machine comprises a bending table mounted on a support turnable about an axis and coaxially carrying an inner bending template surrounded by at least one outer bending template which is shiftable along said axis relative to the inner bending template so that a portion of the tube to be bent may be pressed by clamping means carried by the bending template against the outer surface of the inner or the outer bending template. The bending machine comprises further guide means including a releasable collet for guiding the tube toward the bending templates, the guide means being mounted on the support movable in longitudinal direction of the tube to be bent and in a direction transverse to the longitudinal direction.

摘要： A pipe bending machine has a bending template (10) around which a pipe (13) is bent. The bending template (10) is provided with a position sensor (32) that detects the bending path in dependence on the rotational position. A pushing device (17) engages the unbent portion (13a) of the pipe and urges the same towards said bending template (10). The pushing device (17) is provided with a position sensor (30). The position signals (PS1, PS2) of the two position sensors (32, 30) are compared in a control circuit (41) and an actuation signal (SS) is generated for controlling a pressure controller (42) to adjust the pressure of the drive (22) of the pushing device (17). The actuation signal (SS) is generated such that, in the case of equal position signals (PS1, PS2), the drive (22) of the pushing device (17) is supplied with a pressure that determines the upsetting force exerted on the pipe.

摘要： To fabricate a bent assembly of two metal tubes with one extending through and radially spaced within the other, the bending is done by inserting the smaller through the larger tube producing a tubular work assembly, clamping a leading work portion onto a bending forming die with the inner tube eccentric in the region to be bent against the die-adjacent inner wall portion of the outer tube, bending the region trailing the clamped portion by wrapping onto the bending die, while at (and immediately preceding) the point of feed onto the die the tubes are supported against collapse by a cylindrical mandrel in the smaller tube and a mandrel of crescent cross-section interposed between the large and small tube, in the plane of bending providing reaction support by a slideshoe bearing against the outer tube diametrically remote from the die; the mandrels being axially shiftably supported.
