A sheet material bending system includes a tool changing apparatus that changes tools between a press brake and a tool stocker. The tool stocker is arranged behind the press brake. To change tools from the front and rear of the tool stocker, the front and rear of the tool stocker are opened. The tool changing apparatus has a pivot that is movable in front-rear, left-right, and up-down directions and is rotatable around an axis extending in the up-down direction. A front end of the pivot is provided with tool holding units to hold tools.

A straightening machine having an allocated straightening roll drive including a top bearing frame and a bottom bearing frame, in which a plurality of straightening rolls and supporting rolls are held in a cassette-like manner and arranged in an interchangeable manner. An improved adaptability of a straightening machine to different straightening requirements and straightening areas is achieved in that all the straightening rolls and supporting roils respectively arranged in the top and/or bottom bearing frame are distributed into several straightening roll segments that are modularly adapted to one another and each configured in the form of an interchangeable cassette. Each straightening roll segment includes at least one layer of supporting rolls and at least one allocated straightening roll.

A full-automatic wireless die change cart and system for a press. The full-automatic wireless die change cart includes an upper working table and a lower working table which are connected together up and down of driving devices. The lower working table is driven by a driving device I to move back and forth, while the upper working table is driven by a driving device II to move rightwards or leftwards. Baffles, die lifting arms, and guide rails, all in parallel to one another, are disposed in order from outside to inside at two opposite ends of the upper working table, and push-and-pull devices, baffles, and fixed supporting plate assemblies are disposed in order from outside to inside at the other two ends perpendicular to the two ends.

An installation for planishing running metal product (PM) of strip or plate type includes: a frame (B) in which are disposed a lower planishing cassette (C1) and an upper planishing cassette (C2), a lower drive device (Me1) for driving planishing rollers of the lower cassette in rotation, an upper drive device (Me2) for driving planishing rollers of the upper cassette in rotation. A displacement device (MD) displaces a secured assembly including the lower cassette and lower drive. The displacement device is activated for removal of the lower cassette from the frame toward one side (CM) or for insertion of the lower cassette from the one side into the frame. The secured assembly includes a replacement tool (OR) coupled to the lower cassette on a second operator side (CO) opposite the first motor side in relation to the product running axis (D). A method associated with the planishing installation is also described.

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).

A molding apparatus for molding a metal pipe includes: a gas supply unit which supplies gas into a heated metal pipe material, thereby expanding the metal pipe material; a mold which molds the metal pipe by bringing the expanded metal pipe material into contact therewith; and a drive unit which generates a driving force for moving the mold, in which a replacement unit is replaceably provided with respect to a main body unit having at least the drive unit, and the replacement unit is configured of at least the gas supply unit and the mold.

An apparatus changes rollers of a straightening machine. The straightening machine contains a plurality of cantilever roller shafts for receiving the rollers. The apparatus contains at least a trolley having a device for supporting an entire set of upper and/or lower rollers to be installed in or taken off from the straightening machine. The apparatus further has at least two vertical plates spaced apart horizontally, a device for releasably securing the plates to the trolley, and an actuator connected to the plates and intended to be received in first passages defined in the straightening machine. The actuator is able to reversibly displace the plates and the trolley between a first position wherein the plates and the trolley are close to the straightening machine and a second position wherein the plates and the trolley are spaced apart from the straightening machine.

Hemming dies can be mounted on the respective two clamping jigs (22) of hemming processing stages (S1, S2) each having a turn table as a main part. After the hemming dies are allocated to sub-stages (S11), roller hemming processing is performed by hemming processing robots (1A, 1B) or hemming processing robots (2A, 26). Die storage devices (15A, 15B) for housing a plurality of hemming dies in a line are provided near the hemming processing stages (S1, S2). Hemming dies are changed between the die storage devices (15A, 15B) and the sub-stages (S12) of the hemming processing stages (S1, S2) by first and second die changing robots (17, 19). This makes it possible to provide a roller hemming processing system suitable for roller hemming processing in high-variety low-volume manufacturing.
