A hand-held tool for straightening tubing such as brake fluid lines in vehicles, the tool provides a housing having an outer covering, internally thereof, a series of sets of rollers, that are adjustable radially, supported by end frames, and intermediate the rollers and the outer covering is an adjuster ring, shiftable longitudinally within the housing, operatively associated with the rollers, such that when the adjuster ring is pulled outwardly, longitudinally, from the tool housing, the rollers shift radially outwardly, for accommodating larger tubing, and when the adjuster ring is pushed inwardly of the housing, the rollers are forced inwardly against smaller diameter tubing, in preparation for its straightening. A sector of the tool, usually along a quadrant, is opened from one end to the other of the tool, so as to allow the tool to be applied to the tubing to be straightened, anywhere along its length, and not only at its ends.

A straightening device including: a plurality of rolling members, defining a first channel which is configured for a tubular member to pass therethrough, an extending direction of the first channel being transverse to at least one extending direction of at least one pivot of at least one of the rolling members; at least three shells, each of the at least three shells including two arm portions which are transversely connected with each other, the plurality of rolling members being rotatably disposed between the arm portions, at least one side of at least one of the arm portions having a protruding wall, the protruding wall extending along the at least one extending direction of the at least one pivot and being at least partially overlapped with at least one of the plurality of rolling members as viewed in a radial direction of the at least one pivot.

The invention relates to a straightening machine (1) for straightening an elongated semifinished product with straightening roller elements (6), with a roller table line (3) designed as a conveying section (4), with a stand device (7), which holds the straightening roller elements (6) with respect to the conveying section (4) and comprises a drive-side stand half (17) and an operator-side stand half (18), which is displaceable with respect to the drive-side stand half (17), with a changing device (25) for changing the straightening roller elements (6) and with a changing path (35), along which the straightening roller elements (6) can be moved for changing, in which machine the straightening roller elements (6) are movable on the one hand by means of the operator-side stand half (18) along a first segment (36) of the changing path (35), which extends in a horizontal displacement plane (20), and on the other hand by means of the changing device (25) along a further segment (37) of the changing path (35), which extends in a horizontal changing plane (32), characterized in that the horizontal changing plane (32) is arranged in the region of the physical vertical extent (40) of the operator-side stand half (18).

Drawing and straightening unit (10) having at least one first roller (12) and at least one second roller (16, 17, 18) opposite said first roller (12) with respect to an axis of feed (X) of said at least one metal product (P). The present invention also concerns an apparatus (100), comprising a feed unit (119) and a drawing and straightening unit (10), and a corresponding method to draw and straighten metal products (P) with said drawing and straightening unit (10).

An apparatus for treating metal wire by multiple reverse bending and associated methods for using the apparatus are disclosed. The first roller has a first roller diameter, is followed by N1 intermediate rollers with intermediate roller diameters and ends with an exit roller with an exit roller diameter. The exit roller is larger than the first roller and any one roller in the sequence of rollers has a roller diameter that is not smaller than the preceding roller in the sequence. The progressively larger diameters impose a well-controlled, gradually decreasing curvature to the wire resulting in a cast controlled wire. By folding the wire path together, a compact arrangement is obtained accommodating the increasingly larger rollers. A method to operate the apparatus is also described that allows for an easy adjustment of the apparatus in function of wire thickness.

A multifunction work apparatus includes a drawing and yielding assembly and at least one of either a wire guide assembly, a straightening assembly, or a finishing assembly. The drawing and yielding assembly includes a contrast roll, rotatable idly around its axis of rotation, and at least two motorized rolls positioned on the periphery of said contrast roll.

A three blade fence post straightening device comprises a first row of at least three rollers and a second row of at least three rollers. An axis of rotation of each of the rollers in the first row may be substantially parallel to each other and an axis of rotation of each of the rollers in the second row may be substantially parallel to each other. A forming profile defined between outer surfaces of the respective rollers of each pair of rollers may substantially correspond to a cross section of a three blade fence post, with forming profiles of each pair of rollers being longitudinally aligned to form a substantially straight path through the straightening device. A drive means may be configured to drive each of the rollers in the first row and/or the second row.
