摘要： 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.

摘要： The invention relates to a method for producing a green compact composite comprising at least a first partial green compact and a second partial green compact, wherein, within one pressing cycle, a powder is introduced into a filling chamber and then separated into a first partial quantity and into a second partial quantity, and, within the same pressing cycle, the respective partial quantities are pressed to form a first partial green compact and a second partial green compact and the partial green compacts are amalgamated after the pressing, wherein the amalgamation forms a press fit between the first partial green compact and the second partial green compact and produces a predetermined breaking point in the green compact composite. Furthermore, the invention proposes a green compact composite, a sintered component and also a press, each of which can be based on the proposed method.

摘要： A sintering press includes at least one upper punch and a lower punch, a powder reservoir for filling a female die of the sintering press with at least one powder material that can be sintered, and a female die for producing a green body using the powder material from the powder reservoir. A first punch of the upper punches and/or lower punches has a punch top which is off-center and asymmetric with respect to an axial axis of the sintering press and which can be moved in the female die. The first punch is asymmetric in shape between the punch top and the base, which shape at least reduces an axial tilting of the punch and a lateral drag of the punch top on an adjacent outer surface in the female die during insertion and extraction therefrom during a pressing step in the production of the green body.

摘要： A claw pole stator for a transversal flux motor includes a multiplicity of segments positioned next to one another along a circumferential direction for the annular claw pole stator. Each segment extends from an inner circumferential surface along a radial direction to an outer circumferential surface and is delimited in the circumferential direction by a first side surface and a second side surface and in an axial direction by a first end surface and a second end surface. Each segment is connected by the side surfaces to at least one other segment to form the annular claw pole stator. Segments positioned adjacent each other contact each other by a first contact surface on the first side surface or by a second contact surface on the second side surface and due to the contact surfaces form a form-locking connection in the circumferential direction.
