The present invention relates to a punching tool of a sintering press, comprising at least one lower punch and an upper punch, a first punch of the upper punch and/or lower punch having a top piece that is asymmetric with respect to an axial axis of the punch press. The first punch has a geometry which widens from the top piece towards a base and is also asymmetric with respect to the axial axis of the punch press. The invention further relates to a method for pressing at least one powdery material to a green body in a sintering press.

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.

A radial press is provided including a base, a hollow ring die mounted on the base rotatably relative to a press axis with an inner contour tapering in the direction of the axis and rotationally symmetrical, and a rolling element unit rotatable relative to the axis and having a pressure ring, which surrounds the axis, and a plurality of rolling elements arranged around the axis which are rotationally symmetrical. The rolling elements are supported on the pressure ring at a variable distance from the axis and can roll on the inner contour of the ring die. A rotary drive acts on the ring die or the rolling element unit and effects rotation about the axis. A feed drive also acts on the rolling element unit or the ring die and effects axial displacement of the rolling element unit and the ring die relative to each other.

An adaptor for a press. The adaptor includes a body adapted to removably couple to the press cylinder or carriage of the press and an extension shaft having first and second opposing ends. The first end is removably coupled to the body, and the second end is adapted to couple to a drive adaptor.

As described herein, a multiple row turret module is for use in a rotary tablet press comprising a pressure roll assembly and a turret drive assembly. The multiple row turret module includes a turret comprising a hub selectively engageable by the drive assembly for rotation about a vertical axis. The hub supports a die table and upper and lower guideways defining a plurality of stations. Each station comprises an upper punch opening in the upper guideway and an aligned die opening in the die table and a lower punch opening in the lower guideway. The stations are aligned in a plurality of concentric rows. A plurality of upper punches are provided, one in each of the upper punch openings. A plurality of lower punches are provided, one in each of the lower punch openings. An upper cam assembly is supported above the upper guideway for selectively reciprocating the plurality of concentric rows of upper punches toward and away from the die openings responsive to rotation of the turret. A lower cam assembly is supported below the lower guideway for selectively reciprocating the plurality of concentric rows of lower punches toward and away from the die openings responsive to rotation of the turret. The pressure roll assemblies selectively engage the upper and lower punches responsive to rotation of the turret to compress a granulation into a tablet at the stations.

The invention relates to a method for producing a calibrated combination (I) of parts. The combination (I) of parts comprises at least one first part (2) with a first contact surface (3) and a second part (4) with a second contact surface (5), wherein the parts (2, 4) contact each other via the contact surfaces (3, 5) in the combination (I) of parts; and the parts (2, 4) are designed to be free of an undercut at least with respect to an axial direction (6) and can be moved relative to each other along the axial direction (6) and thereby along the contact surfaces (3, 5) in the calibrated combination (I) of parts. The method has at least the following steps: a) providing the parts (2, 4) in the form of green bodies (7, 8), b) sintering the parts (2, 4) and at least forming bonded connections between the parts (2, 4); c) arranging the combination (I) of parts in a calibrating tool (IO); d) moving the parts (2, 4) relative to each other; e) arranging the parts (2, 4) in order to form the combination (I) of parts; and f) calibrating the combination (I) of parts.

The invention concerns a die insertion tool (100) for inserting a die (550) into a die pocket (552) of a press (500), the tool (100) includes a barrel (102) shaped for positioning the tool (100) within a punch guide bore (582) of the press (500), a tip (106) for insertion into a die cavity (556) of the die (550), and a collar (104) located between the barrel (102) and the tip (106) and configured to contact the die (550) when the tip (106) is inserted in the die cavity (556). The invention further concerns a kit (700) for a press (500) and a method for inserting a die (550) into a die pocket (552) of a press (500).

A tooling assembly is for a powder compacting press machine, which has a lower punch chuck and a core rod chuck. The tooling assembly has: a lower punch with a lower punch drawbar for holding the lower punch in the lower punch chuck in the powder compacting press machine; a core rod with a core rod drawbar for holding the core rod in the core rod chuck in the powder compacting press machine; and a coupling mechanism configured to enable a connection between the lower punch and the core rod. The coupling mechanism has a male coupling element on an outer surface of the core rod and a female coupling element on an inner surface of the lower punch drawbar. The male coupling element is an elastic element.

A dry granulator includes a rack, a feeding device mounted on the rack, and a slip roller device. The feeding device includes a vertical feeding screw, a buffer hopper, a stirring paddle, a horizontal feeding screw, and two drive assemblies. The drive assembly includes a drive motor and a drive shaft. The slip roller device includes a servo motor, a trapezoidal screw, a primary slip roller assembly and a secondary slip roller. The primary slip roller assembly includes a support frame, and a primary slip roller. A guide rail is arranged between the servo motor and the secondary slip roller. The support frame is provided with a screw hole. A coupling member is arranged between the output shaft of the drive motor and the drive shaft. The coupling member includes a reserved space. The horizontal feeding screw and the vertical feeding screw are drivingly provided with a transmission member, respectively.

A rotary press comprises a press frame and a rotor arranged thereon. The rotor has a die plate, an upper punch receiver receiving upper punches, a lower punch receiver receiving lower punches, an upper cam that guides the upper punches, and a lower cam that guides the lower punches. A rotor drive can drive the rotor rotationally. Within at least one dosing station, material is filled into receivers of the die plate for pressing. An upper pressing station has an upper pressing roller and a lower pressing station has a lower pressing roller. Coupling means couples at least one drive that operates the rotary press to the rotor such that, with movement of the at least one drive, the rotor is raised out of its operating position and into a removal position where the rotor can be removed out of the press frame in a lateral direction.
