摘要： Pressing arrangement (100) comprising a pressure vessel (1, 16, 17) and a furnace chamber (18) arranged therein defining a treatment region for an article (5), the treatment cycle including a cooling phase. The pressing arrangement (100) comprises a fan (35) configured to circulate a pressurised gas within the pressure vessel (1, 16, 17) and a heating device (36) for heating the pressurised gas in the treatment region. It further comprises a control and processing module (6) configured to, during the cooling phase: obtain temperature values in the treatment region; based on these values, determine a cooling power for cooling of the pressurised gas in the treatment region; determine a difference between a cooling power required to obtain a selected value of cooling rate of the pressurised gas and the determined cooling power; and based on this difference, control the fan's (35) rotational speed so as to make the difference decrease. If the cooling power provided by the operation of the fan (35) exceeds a cooling power corresponding to the desired cooling rate of the pressurised gas, the control module (6) is configured to, based on the determined difference, heat the pressurised gas using the heating device (36) to make the difference decrease.

摘要： 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.

摘要： A tooling inspection and analysis system measures tooling quality of a multi-tip tablet punch having a barrel with a plurality of tips each having a tip cup for forming a tablet. The system comprises a base. A carriage assembly has a cavity for supporting a multi-tip tablet punch, which when in use is aligned with an X-axis. A Y-axis linear slide mounts the carriage assembly to the base for movement relative to the base along a Y-axis. A sensor is adapted to measure distance. A Z-axis linear slide mounts the sensor to the base for movement relative to the base along a Z-axis. A programmable controller is operatively connected to the Y-axis linear slide, the Z-axis linear slide and the sensor. The controller is programmed to move the carriage assembly and the sensor to automatically align the sensor to measure working length of each tip of a multi-tip tablet punch mounted in the cavity.

摘要： A rotary tablet press has a rotating mold table and top and bottom punches, which can move reciprocally in punch guides, coaxially with the molds. The reciprocating motion of at least the bottom punches is cam-controlled and these punches are acted upon by a releasable punch dampener to prevent an overshoot of their movement and to ensure an action which is as free from wear. It is as maintenance-free as possible whilst maintaining constant damping of the bottom punches. The releasable punch dampener releases with one motion and has a linear release shaft with a release surface and a dampening surface.
