A centering device (1) for centering flat workpieces (700-706) comprises a centering station (100) having at least a first and a second gripping device (300, 301) for gripping the workpiece (700-706), and conveying means for conveying workpieces (700-706) in a conveying direction to the centering station (100). The first and the second gripping device (300, 301) can each be moved horizontally by a first and a second guiding device (200, 201), respectively, and the first and the second gripping device (300, 301) can rotate freely about an axis.

A device (1) for heating filled brioches preferably filled with ice-cream, comprising an upper subassembly (3) and a lower subassembly (4) linked by one or more joints or hinges (10). Each one of the subassemblies (3, 4) includes a heating plate (14) with a cavity (14a) intended to receive the filled brioche, or other similar product, in order to heat it, arranged so that in an operative position they overlap one another. Each heating plate (14) is positioned on top of a heat transfer plate (16) enclosed in a thermoinsulating layer (13), except for an opening to allow contact between the heating plate (14) and the heat transfer plate (16). The heating plates (14) are releasable from the subassembly (3, 4) on which they are arranged by means of one or more releasable fastening elements protruding from the heating plate (14) and inserted in one or more slots (3c, 4c) of either casing of the subassemblies (3, 4).

A method for transferring a workpiece from a first manipulator to a second manipulator by means of a manipulation system in a bending installation having at least one bending machine is provided. Each manipulator comprises first, second, and third manipulator arms, each of which is pivotable about second axes, third axes, and fourth axes and exclusively in a parallel orientation with respect to a first axis of a guide arrangement. The workpiece is grasped by a holding arrangement of the first manipulator. The third manipulator arms are oriented to be opposite and to project towards one another, and the same workpiece is grasped by a holding arrangement of the second manipulator and subsequently released from the holding arrangement of the first manipulator for the direct transfer process. The invention furthermore relates to a manipulation system and a bending installation equipped therewith.

A detaching method of sheets from a stack of sheets from a stack of sheets and a relative detaching apparatus is disclosed, including at least a gripping head of a handling device of sheets and a nozzle assembly apt to eject an air flow to a lateral edge of a stack of sheets, furthermore including: a storage assembly of pressurised air provided at least with a compressed-air tank equipped with a pressure multiplier and a relative first pressure adjuster; and a high-pressure pipe between the nozzle assembly and the storage assembly intercepted by a fast-opening electrovalve. The nozzle assembly is provided with a nozzle, supplied through the electrovalve, configured as a convergent/divergent spout.

Embodiments of the disclosure relate to a transfer pressing apparatus and method for forming car body parts, and more specifically, to a transfer pressing apparatus and method capable of automatically producing car body parts using rolled coils.

A hot metal gas forming and quenching system and process therefor are provided. The system includes a hydraulic press, a die assembly, a rapid heating module and a rapid cooling module. The die assembly includes a progressive die which can realize the hot gas bulging and rapid cooling of the workpiece. Through the above system and the process, making pipes with uncoated plates has a lower cost than with coated and plated steel plates, with fewer structural defects and process risks. By using a progressive die, a resistance heating process, and hot gas bulging and quenching processes are performed in parallel, and the material is loaded progressively, thereby having a fast pace and a greatly improved efficiency. A heating state of parts is fully protected, oxidation is avoided, and no coating is required. After the workpiece is formed, it can be directly welded to a car body without shot blasting.

A workpiece transport unit including a pair of arms, an opening/closing mechanism configured to open and close the pair of arms in a horizontal direction, a pair of first placement surfaces provided at the pair of arms and configured for a first workpiece to be placed thereon, and a pair of second placement surfaces provided at the pair of arms and configured for a second workpiece to be placed thereon.

A stamping strip manufacturing system comprises a stamping machine forming terminals in a strip by stamping, a supply reel around which the strip to be stamped is wound for supplying the strip to be stamped to the stamping machine, and a recovery reel around which the stamped strip is wound for recovering the stamped strip. The system further includes an autonomous mobile robot on which a cutting tool and a welding tool are mounted. The autonomous mobile robot is adapted to cut off an unqualified strip segment of the stamped strip having an unqualified terminal by operating the cutting tool, and to weld two cut ends of the cut strip to each other by operating the welding tool.
