摘要:
A high-efficiency profiling line, comprising: a feeder device (2), equipped with a rotating support (21) for a reel of strip (N); a forming assembly (3), arranged downstream of the feeder device (2), and comprising a plurality of forming assemblies structured to fold the strip (N) longitudinally into a pipe (P); a cutting device (4), arranged between the feeder device (2) and the forming assembly (3), which is equipped with a mobile cutting head (41) structured to translate in synchrony with the strip (N) along an operative stroke, and to cut the strip (N) as it advances at a predetermined speed.
摘要:
A welding machine, comprising: a bearing plane (2), predisposed to support the end portions (A, B) of two tapes to be joined together at the end edges (AS, BS); locking means (31,32), predisposed to block, in a pre-determined position, the end portions (A, B) to be joined one to another; at least a welding head (4), arranged to slide along at least one transverse direction (X); two movable containment elements (51,52) to assume at least one active position, in which they are positioned in contact with the opposite side edges of the end portions (A, B) straddling the end edges (AS, BS).
摘要:
A device for adjusting cutting depth for the removal of weld beads inside profile sections such as tubes and the like, comprising a supporting frame (1) of an elongated shape and transverse dimensions suitable for enabling it to be contained inside a profile section or tube (2), the supporting frame (1) being associated, at one end thereof, with an arm or external rod, the device being characterized in that it comprises: - a plurality of rolling elements (3) associated with the supporting frame (1) at a pre-established mutual distance in a longitudinal direction and that partially project out from the body of the same supporting frame and are capable of coming into contact with the inner surface of the profile section or tube (2) in a zone that is diametrically opposite the one whereon the internal weld bead (4) lies; - at least two rollers (5), which are idle, arranged longitudinally at a pre-established distance from each other, and mounted on small frames (6) that are movable in transverse directions with respect to the longitudinal axis of the supporting frame (1) from an active position, wherein the rollers (5) are in contact with the inner surface of the profile section or tube (2) in the proximity of the internal weld bead (4), to an inactive position, wherein the rollers (5) are not in contact with this inner surface of the profile section or tube (2). The rollers being commanded to shift transversely by a control mechanism having inclined surfaces (7).
摘要:
A cutting-off machine, comprising a cutting unit (2) being enabled to receive a tube (100) and to cut the tube (100) according to a plane transversal to a longitudinal axis (X) of the tube (100), movement means (8) enabled to grip stably a length (S) of cut tube (100) and move said length (S) away from the cutting unit (2) along a direction of advance (A) of the tube (100), and a cutting-off device (5) interposed between said cutting unit (2) and said movement means (8) and configured to realise cutting off of an inner welding seam (200) floating inside said tube (100).
摘要:
A method for cutting manufactured articles (M) comprises steps of advancing a manufactured article (M) along an advancement direction (A) at a predetermined speed; predisposing a cutting device (3) associated with the manufactured article (M) and movable along the advancement direction (A); advancing the cutting device (3); synchronizing the speed of advancement of the cutting device (3) with the speed of advancement of the manufactured article (M); activating the cutting device (3); retracting the cutting device (3); the steps of synchronising and activating the cutting device (3) are comprised between the advancement step and a corresponding retracting step in order to define a cutting cycle of the manufactured article (M). The cutting cycle comprises further steps of re- synchronising the speed of advancement of the cutting device (3) with the speed of advancement of the manufactured article (M).
