    摘要: A plurality of rams in a pressing machine are movable into and out of a predetermined position to compress power material and shape a die-formed part. The rams are advanced to a pre-selected spaced relationship to form a desired configuration of the die-formed part. Strain gauges are mounted on each ram to detect during the pressing operation elastic deformation, altering the dimension of the ram and the shape of the die-formed part. In response to detected elastic deformation, the strain gauges transmit a signal through a controller to a readout device for recording the magnitude of ram deformation. Thereafter, the press drive mechanism is actuated to move the rams to compensate for the change in dimension of the rams so that the rams are repositioned to maintain the desired spaced relationship for a predetermined configuration of the die-formed part.

    摘要: Precision compacts are produced from powdered material in a mold having at least one top plug and at least one bottom plug between which plugs the powdered material is compressed. The course of the pressing force of at least one of the plugs is detected as a function of the path of its travel during compression, and compared with a predetermined path-dependent tolerance range of the pressing force. Upon exceeding such tolerance range, the final pressing position of the plug in question is changed in such a manner that the height of the compact in such final pressing position is reduced by an amount corresponding to the increased springing back of the compact upon its removal from the mold that results from the greater final pressing force. In the absence of exceeding such tolerance range, the final pressing position of the plug in question is changed in such a manner that the weight of the compact in such final pression position is increased by an amount corresponding to the decreased springing back of the compact upon its removal from the mold that results from the lesser final pressing force.

    摘要: A toolset for forming a component from a powdered metal charge includes a die having two zones on the sidewall. Lubricant is applied to one of the zones. The powdered metal charge is initially compressed to an intermediate density and the lubricated zone of the sidewall brought into contact with the partially compressed charge. The charge is then further compressed to a final density.

    摘要: A multiple-acting powder metal press is disclosed for making green form double helical gear compacts. The press has inner and outer lower punches, and an upper, outer punch. The upper and lower outer punches have left hand and right hand external helical profiles as chosen to produce a desired helical gear. The punches co-operate with left hand and right hand helical dies carried by the press about the punches. The helical faces require that the dies rotate relative to the punches during operation. A cam and roller mechanism may drive this rotation. The compact forming process commences with an open position in which powder is introduced to a vacant lower die cavity. The upper portions of the press advance downward to close the cavity. All parts of the press except the lower inner, or transfer, punch then move downward at the same speed to transfer powder to the extremities of the cavity. When transfer is complete both lower punches may be stopped, while the upper punches continue to advance. The dies advance at half the speed of the upper punches, rotating partially as they do so. Once the powder reaches its compacted density the upper and lower punches cease motion, but the dies continue to turn, separating themselves and compressed part. Finally the part is ejected and the press returns to the initial condition.
