MOULD, METHOD FOR PRODUCING A GREEN COMPACT AND USE OF THE MOULD
A mold for producing a green compact using powder metallurgy processes has an upper punch and a lower punch which are movable along a common press axis and a die body with a charging chute for receiving powder material. The die body has an upper region in which the upper punch is movably guided along the press axis in the charging chute, and a lower region in which the lower punch is movably guided along the press axis in the charging chute. Two cross slides realize a forming region which determines the lateral outside contour of the green compact, and are arranged on the die body so as to be displaceable in a direction which deviates from the press axis. The two cross slides only move into contact with one another when the two cross slides are arranged in their respective end position.
Manufacturing a hard-metal pressed article
Manufacturing a hard-metal pressed article includes providing a multi-part die, feeding at least one frontal mold part, feeding at least one transverse mold and locking the at least one frontal mold part and the at least one transverse mold part to define a cavity for the article. Feed directions of the at least one frontal mold part and the at least one transverse mold part are inclined. The at least one frontal mold part and the at least one transverse mold part define surfaces of the article. The resulting cavity includes at least one opening through which a punch is insertable. Next, a filling shoe is fed above an opening of the cavity and fills the cavity with a powder, and the powder is compressed with at least one punch. The feeding of the transverse mold part takes place along a feed direction that is parallel to the main pressing direction.
METHODS OF MAKING POLYCRYSTALLINE DIAMOND BODIES HAVING ANNULAR REGIONS WITH DIFFERING CHARACTERISTICS
Polycrystalline diamond bodies having an annular region of diamond grains and a core region of diamond grains and methods of making the same are disclosed. In one embodiment, a polycrystalline diamond body includes an annular region of inter-bonded diamond grains having a first characteristic property and a core region of inter-bonded diamond grains bonded to the annular region and having a second characteristic property that differs from the first characteristic property. The annular region decreases in thickness from a perimeter surface of the polycrystalline diamond body towards a centerline axis.
PRODUCTION SYSTEM FOR MACHINING WORPIECES
Production system for machining workpieces including a transfer comprising receiving and passing on the workpieces for machining from process Station to process Station in a chamber, such as a pressing unit. In the production system, logistical and technological processes are improved by implementing unmanned aerial vehicles (UAV). The UAV is used for process Support monitoring the production process of one of the workpieces or the transfer of the workpieces.

GAS-BASED MATERIAL COMPRESSION AND PORTIONING
An apparatus includes a fixed assembly and a reciprocating assembly. The fixed assembly includes a hopper, a first gas manifold, and a dispensing chamber, and the reciprocating assembly includes a channel assembly defining a channel conduit, a shield plate vertically aligned therewith, and a second gas manifold. The reciprocating assembly may move, in relation to the fixed assembly, to a first position to enable the channel conduit to be filled with bulk compressible material from the hopper, a second position to enable compressible material to be pushed from the channel conduit to the dispensing conduit and to be compressed in the dispensing chamber according to a first gas directed through the channel conduit by the first gas manifold, and a third position to enable the compressed material to be pushed out of the dispensing conduit according to a second gas directed through the dispensing conduit by the second gas manifold.

Powdery-material feeding device and powdery-material feeding method
A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.
HOT FOIL STAMPING PRESS
A hot foil stamping press has a pressing system for pressing a foil onto a sheet, a blow unit which is positioned at a distance to the pressing system for directing a stream of gas between the sheet and the foil. The stream of gas to detaches the foil from the sheet after each stamping cycle. A gripper bar is arranged between the blow unit and the pressing system for gripping the sheet. A flow guiding element is arranged between the blow unit and the pressing system, preferably on the gripper bar, for directing the gas from the blow unit between the sheet and the foil. Said element avoids the losses in the stream of gas due to the aperture that exist between the grippers in a typical gripper bar.
MOTION SETTING METHOD FOR TRANSFER PRESS AND TRANSFER PRESS
A transfer press includes a press machine that moves a slide up and down in accordance with pressing motion, and a transport device that moves a retainer in accordance with transfer motion to transport a workpiece. The transfer press includes a creation unit, a determination unit, and a phase adjustment unit. The creation unit creates a three-dimensional operating curved surface based on the provisionally set pressing motion and the provisionally set transfer motion. The determination unit compares a standard upper die interference curved surface with the operating curved surface in the same three-dimensional coordinate system to determine whether the operating curved surface is present within an interference region of the standard upper die interference curved surface. The phase adjustment unit changes a relative phase of the transfer motion relative to the pressing motion when the operating curved surface is present within the interference region.
