  • Patent number: 10427209
    Abstract: A method of forming a part from a blank includes positioning the blank within a forming die. Water is introduced between the blank and the forming die. The water is heated to form steam between the blank and the forming die. The blank is reshaped within the forming die to form the part while the steam is disposed between the blank and the forming die. The steam forms a cushion between the blank and the forming die to reduce friction therebetween. A lubricant is not applied to the blank prior to being positioned in the forming die. Therefore, the formed part does not require a washing step after being formed.

  • Patent number: 5020350
    Abstract: The invention includes apparatus and method for lubricating and cooling a workpiece, dies or ironing rings, and punch at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article.A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers.

    Abstract: The invention relates to a method and apparatus for open-die forging of workpieces in forging presses at high forging temperatures, more particularly steel billets or ferrous alloy billets between about 800 and 1250 degrees Celsius. In conventional open-die forging it is often not possible to complete the forging process in a single heat, and the workpiece must therefore be reheated. Also, with direct contact between workpiece and tool, cracks occur, particularly in the vicinity of bulges, the prevention or straightening of which requires repeated transverse hammer- or pressure-forging, so lengthening the cooling time. The total energy consumption for deformation and heating of the workpieces is therefore relatively high.

  • Patent number: 4467629
    Abstract: A steel strip is first passed longitudinally in a predetermined travel direction through a nip between a pair of parallel rolls, and then passed downstream in the direction from the rolls over a sensor that engages the strip at a plurality of zones spaced apart on the strip transverse to the direction. The sensor generates respective output signals corresponding to the deviations from planarity of the strip at the zones. A treatment liquid is sprayed uniformly and at a relatively high temperature on the rolls while respective streams of a coolant liquid at a relatively low temperature are directed at regions of the rolls corresponding to the zones. The heat exchange between the streams and the rolls is varied in accordance with the respective output signals to thermally change the diameters of the rolls in the respective regions and thereby eliminate the deviations in planarity detected by the sensor.
