Abstract: The modular ceramic and/or metal powder press assembly comprises a die (12), a lateral adjustment drive module (18) for adjusting a transverse punch in a lateral adjustment device, and a holding device (15) including an inside holder for the die and an outer-side housing (17) for attaching the lateral adjustment drive module. The housing has an edge portion with a first engagement formation. The lateral adjustment drive module has a second engagement formation of the edge portion. The first and second engagement formations are interlocked in a main press direction. The modular ceramic and/or metal powder press assembly comprises a die (12), a lateral adjustment drive module (18) for adjusting a transverse punch in a lateral adjustment device, and a holding device (15) including an inside holder for the die and an outer-side housing (17) for attaching the lateral adjustment drive module. The housing has an edge portion with a first engagement formation. The lateral adjustment drive module has a second engagement formation of the edge portion. The first and second engagement formation are interlocked in a main press direction or main extrusion direction or interlocked at an angle of less than 46[deg] to the main extrusion direction. The holding device has a circumferential support section at an angle of greater than 30[deg] , greater than 60[deg] , greater than 75[deg] , greater than 90[deg] or 90[deg] relative to the main pressing direction. The lateral adjustment drive module is inserted on the circumferential support section in the lateral adjustment device or at an angle of less than 20[deg] , less than 40[deg] or less than 60[deg] relative to lateral adjustment device. The first and second engagement formations are present in an assembled state, are offset in a fixing plane parallel to transverse punch displacement plane in the lateral adjustment device and engage to each other. The lateral adjustment drive module is supported in a region between the fixing plane and the transverse punch displacement plane. The first and second engagement formations have longitudinally extending paths, and provided on facing surfaces transverse to a direction of travel of a rounded profile. The longitudinally extending path is an arc-shaped curve. The holding device includes a fixing device for receiving the die directed away from the first engagement formation by a force. The lateral adjustment drive module includes the transverse punch of a gearbox and a drive. The drive is laterally arranged to the gearbox .The drive and the gearbox are connected to each other via a belt or gear that is pivotally mounted about a gear axis of the gearbox and/or about a drive axis of the drive. The transverse punch includes an adjusted mechanism. The gearbox is located in first and second housing portions. The first and second housing portions are pivotable relative to one another. The second housing portion is fastened or connected to the holding device. The gear box is arranged radially outside the holding device. The lateral adjustment drive module further comprises an eccentric drive. The transverse punch is arranged parallel to a displacement plane of the adjusted mechanism. An independent claim is included for a ceramic and/or metal powder press or an adapter.
