  • Patent number: 11897220
    Abstract: In a method for measuring or calibrating utensils, in particular in pressing processes, different dimensions and/or positions of the utensils, such as tools, stamps, die units, chucks or the like, are determined. A measuring device is provided, with which the utensils are placed relative to one another in the press as in the installed state and are displaceable relative to one another at least in the axial direction of the opening in the die unit forming the die and are measured and/or calibrated individually and relative to one another. The pressed parts and workpieces to be produced using a press can thus be manufactured in a highly precise manner, moreover in high numbers using the same utensils.

  • Publication number: 20220152967
    Abstract: In a method for measuring or calibrating utensils, in particular in pressing processes, different dimensions and/or positions of the utensils, such as tools, stamps (16, 17), die units (22), chucks (14, 15, 21) or the like, are determined. A measuring device (10) is provided, with which the utensils are placed relative to one another in the press as in the installed state and are displaceable relative to one another at least in the axial direction (A) of the opening in the die unit (22) forming the die and are measured and/or calibrated individually and relative to one another. The pressed parts and workpieces to be produced using a press can thus be manufactured in a highly precise manner, moreover in high numbers using the same utensils.

  • Patent number: 10899100
    Abstract: Powder press having preferably stamps which are movable for a transverse press in a feed housing. The stamps partially delimit a hollow chamber of a matrix in the feed housing and are able to be coupled to a press device by one connector piece each. An adjustable positioning device, which is formed from a wedge arrangement having a stop surface and placed crosswise to the moving direction of the stamp, is allocated to the respective stamp for determining the pressing position thereof. The wedge arrangement includes at least one wedge which is adjustable crosswise to the moving direction of the stamp and has the stop surface which contacts a stop surface at the stamp. Such a wedge arrangement can achieve very accurate pressing positions of the stamp, and extremely stable positioning of the stamp to be pressed with high pressure.

  • Publication number: 20180036982
    Abstract: The invention relates to a powder press having preferably a plurality of stamps (11) which are movable for a transverse press in a feed housing (10), said stamps partially delimiting a hollow chamber of a matrix in the feed housing (10) and being able to be coupled to a press device (40) by one connector piece each. An adjustable positioning means, which is formed from a wedge arrangement (20) having a stop surface (22) and placed crosswise to the moving direction of the stamp (11) is allocated to the respective stamp (11) for determining the pressing position thereof. Said wedge arrangement (20) comprises at least one wedge (21), which is adjustable crosswise to the moving direction of the stamp (11) and has the stop surface (22), which contacts a stop surface (11?) at the stamp (11). Such a wedge arrangement can achieve very accurate pressing positions of the stamp, first of all, and extremely stable positioning of the stamp to be pressed with high pressure, second of all.
