A device for producing a gear green compact from a powder includes a die, an upper stamp, and a lower stamp, wherein the die has at least one helical toothing on an inner lateral surface, which helical toothing extends only over a partial area of the circumference of the inner lateral surface, and which has a first helix angle, wherein, adjoining the first helical toothing in a circumferential direction, one toothed edge surface is formed on each side, both of which have a second helix angle, wherein at least one of the second helix angles of the die is unequal to the first helix angle of the helical toothing of the die.

Device for producing a gear green compact

A method for producing a sintered component, in particular an annular sintered component, with a toothing, having teeth with tooth roots, tooth tips and tooth flanks, includes the steps of pressing a powder to form a green compact, sintering the green compact, and hardening the sintered component, wherein after sintering, the tooth flanks and possibly the tooth tips are post-compacted and subsequently undergo post-processing by machining, and wherein a transition region between the tooth flanks and the tooth roots has an undercut design, and post-compaction of the tooth flanks is carried out only up to this transition region.

Method for producing a sintered component with a toothing

The invention relates to an assembly () at least comprising a first metal component () having a first surface region () and a second metal component () having a second surface region (), wherein the two surface regions () face each other, and the first and the second component () are connected cohesively together at least in a subregion of the two surface regions (), and wherein at least one of the two metal components () is a sintered component, wherein that surface region () of the sintered component that has the cohesive connection has a higher density than the adjoining further surface region of the sintered component.

Assembly having two components connected cohesively together

A method and a device stretches and forms a foil blank and a product is produced by this method. The foil blank is stretched in at least one direction and slides along in at least one direction during the deformation. The sliding along may be controlled, and the clamping force and the clamping speed may be regulated.
