Abstract
A device for a press for shaping a sheet metal part with a section which can be shaped out separately as an undercut in the device. The device includes a press-side ram, a swage and a die which can be driven separately, serves to shape out the undercut, and interacts with an undercut contour which is arranged substantially in a filler slide which is mounted such that it can be moved rotationally in the swage. The filler slide can be transferred from a shaping-out position into a position which exposes the undercut in the sheet metal part, and vice versa. At least one temperature-control device is provided in the filler slide, by way of which temperature-control device the filler slide can be temperature-controlled at least in sections.
Claims9
A device for a press for forming a sheet-metal part with a portion which, as an undercut, is separately moldable in the device, comprising:
- a press-side ram;
- a swage;
- a filler slide rotatably mounted in the swage about a rotation axis;
- and
- a die which is separately drivable, serves to mold the undercut, and interacts with an undercut contour, the undercut contour being disposed substantially in the filler slide, wherein
- the filler slide is transferable between a molding position and a position which exposes the undercut in the sheet-metal part, and
- a plurality of variable temperature control installations are arranged in the filler slide in a longitudinal direction of the filler slide, which is parallel to the rotation axis, each of the plurality of variable temperature control installations being variably temperature-controllable to a dissimilar temperature relative to one another, wherein the filler slide is temperature-controllable at least in portions via temperature control of at least one of the plurality of variable temperature control installations.
