发明名称 TOOL AND METHOD FOR PRODUCING STAMPED PARTS
摘要 An upper die part includes an embossing bell, a stripper ring, and an inner shape embossing element. The stripper ring has an embossing surface with a corrugated profile on the embossing surface. A lower die part includes an embossing anvil having a corrugated profile on its embossing surface. The embossing bell and the inner shape embossing element each are provided with an embossing shoulder, which are disposed, with respect to the corrugated profile of the stripper ring, in the stroke direction in such a way that the shoulders can seize the burrs only alter the corrugating step. The corrugating step takes place prior to burr compression. The outer and inner contours of the disk are not able to change positions, but are able to change shapes on the burr side after the corrugating step.

主权项 1. A tool for producing stamped disks, comprising: an upper part and a lower part, which form at least one stamping or fine blanking stage for cutting the outer contour and inner contour of a disk blank and at least one corrugating and embossing stage for corrugating the disk blank and for compressing the burrs that developed during cutting, the corrugating and embossing stage being divided into an upper die part and a lower die part, wherein the upper die part comprise: an embossing bell,a stripper ring ring, which is provided with an embossing surface and has a corrugated profile on the embossing surface, andan inner shape embossing element, and wherein the lower die part comprises:an embossing anvil having a corrugated profile on the embossing surface thereof,wherein the embossing bell and the inner shape embossing element are each provided with an embossing shoulder, which are disposed, with respect to the corrugated profile of the stripper ring, in the stroke direction,wherein the shoulders are configured to seize the burrs only after a corrugating operation, and so that the corrugating operation takes place prior to compression of the burr, and the outer contour and inner contour of the disk are not able to change positions, but are able to change shapes on the burr side after said corrugating operation.
