The invention relates to a powder press, comprising a tool structure, which has a conical substructure having lower rams nested in each other, wherein each lower ram has a longitudinal extent, in particular a cylindrical longitudinal extent, which is guided in a die, wherein, in the case of at least two longitudinal extents of the lower rams, each longitudinal extent is adjoined by a conical enlargement, wherein the conical enlargements can be guided in each other, wherein the region of the conical enlargement has an inner wall and an outer wall, which expand conically and which are preferably longer than the longitudinal extent. The invention further relates to a method for operating a powder press and to a computer program product having computer program code means that can be executed on a computer system in order to perform the method.

The present invention relates to a punch unit of a powder press, wherein the punch unit is assembled from at least two parts, in this case comprising a headpiece as the first part and a widening region, adjoining the headpiece, as the second part, wherein the widening region flares to a diameter of a punch bolder which is directly attachable to an end, located away from the headpiece, of the widening region. Furthermore, punch units of a powder press that slide one inside another, a powder press itself and a method for operating a powder press are proposed.

The present invention relates to an apparatus, preferably a press, comprising a cavity which is to be filled and at least a first material feed, for a first material, and a second material feed, for a second material, wherein the first and the second material feeds are arranged separately from one another, having a feeding apparatus for feeding the first and the second materials into the cavity which is to be filled, wherein the feeding apparatus has a mouth-opening cross section with at least a first region of the mouth-opening cross section for the first material, and with a second, separate region of the mouth-opening cross section for the second material, for filling the cavity preferably in parallel, and at separate locations. A method and also a blank are proposed in addition.

A method of manufacturing an end piece for a camshaft may include forming a shape of an end piece to be coupled to a camshaft by compacting steel and powder in a net-shape manner and by sintering steel and a powder compact that are preassembled to each other.

The invention relates to a powder press (1) for producing a pressed article from a material that can be pressed, having a press frame (10), an upper and/or lower punch assembly (14) and a die assembly, which define a molding cavity, into which the material that can be pressed can be introduced, and an electric drive unit (12) which is operatively connected to the punch assemblies (14) and/or the die assembly, wherein, in order to mold the pressed article, the punch assemblies (14) and the die assembly can be moved relative to each other along a pressing axis (18) and pressed against each other by means of the electric drive unit (12). Furthermore, the operative connection between the electric drive unit (12) and one of the punch assemblies (14) comprises a toggle lever drive (16) which moves the punch assembly (14) into a pressing end position along the pressing axis (18).

A molding die includes a first die having a through-hole; a second die inserted into the through-hole and configured to be movable relative to the first die; and first and second punches configured to be insertable into the through-hole, wherein an undercut molding part is provided on the second die, and a molding target is compression-molded in a cavity surrounded by inner side walls of the through-hole, the second die, the first punch, and the second punch.

A method of manufacturing an end piece for a camshaft may include forming a shape of an end piece to be coupled to a camshaft by compacting steel and powder in a net-shape manner and by sintering steel and a powder compact that are preassembled to each other.

The present disclosure generally relates to an article used in the manual transmission gearbox in automobiles. More particularly, it relates to an article used in manual transmission gearbox, namely the shifter dog, composition used for manufacturing the shifter dog and a method of manufacturing the shifter dog.

A plane plate for a pressing tool of a press in which the plane plate for activating a punch of the press by way of at least one lifting cylinder is displaceable along an axial direction. The plane plate has a link to the at least one lifting cylinder, a centrally disposed receptacle 9 for contacting the punch or a punch holder of the press and at least one at least partially cylindrical guiding face which for contacting a first guide column is parallel with the axial direction. The plane plate has, in at least a first cross section which runs through the link and the receptacle parallel with the axial direction and along a radial direction that runs so as to be perpendicular to the axial direction, at least a first region, between the link and the receptacle, having a wall thickness, wherein the wall thickness in the first region and so as to be spaced apart from the receptacle as well as from the link has at least a minimum.
