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 method for controlling a production process for components, wherein the components or a production device used for producing the components have or has features which are metrologically detectable. The method comprising specifying a test plan for detecting primary feature(s) and secondary feature(s) by tests, wherein the primary feature(s) is/are measured at a first test frequency and the secondary feature(s) is/are measured at a second test frequency, wherein at least one stability criterion is defined for the primary feature(s); producing the components and carrying out the test plan for producing test results in parallel, wherein solely the primary feature(s) is/are tested at the first test frequency; evaluating the determined test results; and, if at least one test result for the primary feature(s) violates the stability criterion, continuing the carrying out of the test plan, wherein at least a secondary feature is tested.

摘要： Method for controlling a production process for producing components, wherein the components or a manufacturing device used to produce the components has/have at least one first feature which can be captured using metrology; at least having the following steps: a) determining a test plan for capturing the first feature with a first value of a first test frequency, wherein at least one first stability criterion is defined for the first feature; b) producing the components and carrying out the test plan in a parallel manner, wherein the first feature is tested at the first test frequency; c) evaluating the test results; d) changing the first test frequency, wherein the first test frequency is increased if at least one test result for the first feature violates the first stability criterion; wherein the first test frequency is reduced if all test results are in accordance with the first stability criterion.

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.

摘要： 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.

摘要： A method for operating a pump assembly, wherein the pump assembly has at least one first drive means for conveying a fluid and an electric motor for driving the first drive means, the electric motor comprising at least one stator and one rotor, the rotor being connected at least to the first drive means via a driveshaft. The electric motor draws power at least: i. in order to heat the rotor by means of induction; or ii. in order to drive the rotor, the driveshaft and the first drive means so that these components rotate about a common rotation axis at a speed of more than “0” revolutions per minute.

摘要： The invention relates to a method for producing a sintered part with a high radial precision. The sintered part is made of at least one first joining part to be sintered and a second joining part to be sintered, and the method has at least the following steps: joining the first joining part with the second joining part, and bringing about the high radial precision, having a step of deforming at least one radial deformation element which is preferably positioned so as to adjoin a joint contact zone, wherein the deformation of the radial deformation element is caused at least by means of a calibration tool and is carried out at least substantially as a plastic deformation of the radial deformation element. The invention further relates to a set of parts for joining the joining parts to be sintered into a sintered part with a high radial precision.
