The present invention generally relates to the modification of a deep-drawing sheet blank (P) for electric resistance heating. Generally, the modified sheet blank comprises slits (Z) being made in the edges of the blank (P) transversely to the electric current flow and oriented towards the perimeter of the forming zone (T). The distances between the ends of the slits (Z) and the forming zone (T) perimeter may be equal. The ends of the slits (Z) oriented towards the forming zone perimeter (T) may also be rounded.

A cutting method using a stamping press according to the present disclosure is a method to cut a workpiece that is configured from a first metal sheet and a second metal sheet joined at a weld portion and that has a heat-affected zone around the weld portion, in which the workpiece is cut using a punch. The punch includes a flat portion and a projecting portion projected more toward the workpiece than a flat portion of the punch. The workpiece is positioned with respect to the punch at a position such that the projecting portion starts cutting at least at one out of the heat-affected zone or the weld portion before the flat portion cuts the workpiece. The workpiece is then cut by moving the punch and a die relative to each other in this state of positioning so as to shear across the weld portion on the workpiece.

The invention relates to a method and to a device for heat treating a metal component. The method comprises at least the following steps: a) heating the component; b) setting a temperature difference between at least one first sub-region and at least one second sub-region of the component; c) at least partially forming and/or cooling the component in a press hardening tool; and d) mechanically post-processing the at least one first sub-region of the component.

A hot-stamped and trimmed part is produced by hot pressing a blank and then cutting off an excess outer peripheral portion by laser machining, an outer peripheral shape of the hot-stamped and trimmed part includes a laser trim line formed by cutting in the laser machining, and a press trim line formed by shearing in the hot pressing or pressing performed before the hot pressing, and the laser trim line and the press trim line are connected via a projecting corner portion.

A press tooling includes a distance member pivotably supported by a holder; and a moving device provided on a first die unit. The holder is provided in a movable manner with respect to a punch in a press direction, and a pad is provided in a movable manner with respect to a die in the press direction. The distance member is pivotable between a home position in which the distance member does not come into contact with the second die and a preventive position in which the distance between the pad and the holder in the press direction is prevented from being equal to or less than a predetermined distance. As the holder moves relative to the punch in the first direction, the moving device causes the distance member to pivot from the home position toward the preventive position.

The present invention relates to a method for producing a dimensionally stable sheet metal component, wherein the method includes preforming a metal sheet into a sheet metal preform comprising at least one base region, a frame region, a transitional region between the base region and the frame region, optionally a flange region and a transitional region between the frame region and the flange region, wherein at least one of the regions comprises excess material at least in portions. The sheet metal preform is cut at least in portions to form a cut sheet metal preform with a sheet metal preform The sheet metal preform is one of swagged and calibrated which has been cut at least in portions to form a substantially finished formed sheet metal component.
