Publication number: 20230052794Abstract: A welding machine, preferably of the flash butt welding type, designed to facilitate maintenance of the clamping means, e.g. clamps, of the two longitudinal metal products to be welded. Advantageously, a first structure, provided with first clamping means, and a second structure, provided with second clamping means, are supported in a first part of the carriage delimited by a first beam and a second beam of the carriage parallel to the feeding direction, while at least one transformer is fixed to the carriage and supported in a second part of the carriage, arranged laterally outside the first part.Type: ApplicationFiled: February 2, 2021Publication date: February 16, 2023Inventors: Daniele Russian, Giuseppe Bordignon, Rolando Paolone, Claudio Tomat

Publication number: 20090044884Abstract: Treatment process for stainless steel bars, in particular a solution quenching, to be performed directly in-line downstream of the rolling mill which makes it possible to obtain a material devoid of intergranular corrosion and with microstructural characteristics suitable for subsequent uses. Advantageously, said process also makes it possible to improve the productivity of the entire rolling plant. The treatment is suitable to be performed on austenitic, ferritic, or austeno-ferritic stainless steel bars, Al—Cu alloy bars, Nickel alloy bars, and all other alloys requiring rapid cooling in order to prevent undesired phase precipitations. Prevention of intergranular corrosion obtained with the treatment process of the invention makes it possible to prevent problems, and relative costs, during surface treatment of the bars and those that could occur in final use.Type: ApplicationFiled: October 21, 2005Publication date: February 19, 2009Inventors: Francesco Toschi, Rolando Paolone

Patent number: 7424987Abstract: Coiling device (10) and relative coiling method for rolled or drawn long products, comprising a mandrel (11), arranged cantilevered and rotatable with respect to a central longitudinal axis (X), and on which the long products are wound in adjacent and superimposed spirals (33), in order to form a compact coil (31) having the geometric shape of a circular ring with lateral flanks substantially orthogonal, or very angled, with respect to the central longitudinal axis (X). The mandrel (11) comprises a flange (12) substantially orthogonal, or very angled, with respect to the central longitudinal axis (X) which defines a first lateral flank of the coil (31). The mandrel (11) also comprises first arm elements (13) which define the cylindrical surface of the core that forms the coil (31), and second arm elements (14), opposite the flange (12), which define a second flank of the coil. The first and the second arm elements (13,14) are mobile between a first coil-forming position and a second coil-removal position.Type: GrantFiled: January 17, 2005Date of Patent: September 16, 2008Assignee: Danieli & C. Officine Meccaniche SpAInventors: Giuseppe Bordignon, Ivan Paiaro, Andrea De Luca, Rolando Paolone

Patent number: 6679426Abstract: In a machine for counting bars, for example metal bars, that are to be sent on to a packaging station which packages a pre-set number of them in bundles, the problem of precise counting of the bars is solved by using, for the conveyance of the bars to the counting station, a screw conveyor, in which each groove of the screw has a wall having a pitch increasing more rapidly as compared to the normal pitch of the screw, thus making it possible, in the case where more than one bar is present in the same groove, to render the lying plane of the bars not parallel to the specific axis of the counting means. This is obtained by providing one of the faces of the grooves either with a special step having a continuously increasing width, or with a continuously increasing inclination.Type: GrantFiled: November 8, 2000Date of Patent: January 20, 2004Assignee: Danieli & C.

Patent number: 5400909Abstract: Device to discard short bars shorter than a predetermined length from a plurality of bars being fed by feeder that comprise a plurality of first conveyor chains (14a) and a matching plurality of second conveyor chains (14b), on which the bars (11) are positioned perpendicular to the conveyor chains (14) and are fed in a direction at a right angle to the lengthwise extent of the bars (11), the downstream ends of the first conveyor chains (14a) and upstream ends of the second conveyor chains (14b) being progressively staggered so as to define a separation channel (13) positioned at an angle to the axis of feed of the bars (11), an angle of between 10.degree. and 45.degree. being defined between the separation channel (13) and the axis of the bars (11), the separation channel (13) cooperating with a bridge to support ends of bars of at least the predetermined length.Type: GrantFiled: July 18, 1994Date of Patent: March 28, 1995Assignee: Danieli & C.
