Tools for punching machines for reshaping at least one portion of a plate-shaped workpiece are described. The tools have a first tool portion that includes a first device configured to be held in a first tool holder of the punching machine and a bending stamp having a bending edge and a second tool portion including a second device configured to be held in a second tool holder of the punching machine and a bending roller configured to cooperate with the bending stamp to reshape the plate-shaped workpiece. The bending roller is rotatable around a rotation axis running parallel to the bending edge. The bending roller includes a sector-shaped notch formed along the rotation axis and formed, at least in part, by first and second bending shank edges. The bending roller includes a plurality of second bending segments positioned on the rotation axis to rotate about the rotation axis.

There is provided a production method for a hat-shaped steel sheet pile including performing rough rolling, intermediate rolling, and finish rolling on a material to be rolled through hot rolling, and then performing bending forming, in which the material to be rolled is composed of a web corresponding part, flange corresponding parts, arm corresponding parts, and joint corresponding parts, corner parts as worked parts are formed at connection places between the web corresponding part and the flange corresponding parts and connection places between the flange corresponding parts and the arm corresponding parts, the intermediate rolling is carried out by performing rolling in a plurality of passes on the material to be rolled in a hot state by using a caliber provided to upper and lower caliber rolls in one or a plurality of intermediate rolling mills in which one stand is configured by one caliber, at a height lower than a predetermined target product height, the bending forming is performed in a hot state and performed in a state where the worked parts have a temperature of transformation point or higher, and in the bending forming, the material to be rolled is formed to have predetermined target height and target width.

A monitoring device monitors a forming machine (target device). The forming machine includes a housing, a bearing attached to the housing, and a shaft placed radially inside the bearing. The monitoring device includes a plurality of heat flux sensors and a detector. The heat flux sensors are provided on the radially outer side of the bearing and spaced from each other in the circumferential direction of the bearing. The heat flux sensors output a signal corresponding to heat fluxes through faces thereof on the bearing side and faces thereof on the other side. The detector detects a load applied radially to the shaft or bearing, based on the output from the heat flux sensors.

A metal roof panel includes a rib with a unique shape. The rib is bilateral with upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex. Between each rib is a channel, preferably including at least one raised surface. The lower surface of the channel between the raised surfaces, and the top of the raised surfaces, are substantially planar and parallel to the flat surface of the apex of the panel. A unique method of manufacturing the roof panel employs a roll machine configured to shape a piece of sheet metal into the roof panel by modifying the shape in many small increments, which allows the final product to have a fairly intricate bend pattern.

A process and assembly for flanging or hemming an edge of an aluminum casted article, including positioning each of a heating element and a holding pad in proximity to an extending edge of the casted article, heating the edge of the casted article corresponding to the placement of the heating element, and then applying a roller or flattening tool having a contact portion for engaging and bending the heated edge until reformed into a final bent or folded profile. Additional steps include repositioning the at least one heating element or positioning at least one additional heating element at a further location of the casted article, following which a subsequent trimming or final fabricating step is employed to complete the article.
