Definitions

  • the present invention relates generally to devices for forming materials and, more particularly, to wear components of a die, mold, and/or stamping device.
  • Dies, molds, and stamping devices are commonly used for cutting or forming material, such as sheet metal, as part of a manufacturing process.
  • Such devices typically include one or more wear components for absorbing various forces that may be generated during the cutting and/or forming processes.
  • the wear components may be, for example, a wear plate, a bushing, a gib, or a U-block.
  • Various other wear components are known.
  • upper and lower heel blocks coupled to upper and lower die shoes, respectively may be equipped with corresponding wear plates to absorb at least a portion of the side thrust forces that may be generated as the upper die shoe is lowered toward the lower die shoe.
  • Other wear components such as bushings, gibs, or U-blocks may function as a bearing for permitting a second machine component to rotate and/or translate thereon. Wear plates may also be used for this purpose.
  • a wear component may be gradually worn down by frictional forces generated as a result of the relative motion between the wear component and another component.
  • Various other applications and configurations of wear components are also known.
  • Typical wear components are constructed of a low friction material such as bronze, bronze-plated steel, or a bronze alloy, for example, an aluminum- bronze alloy.
  • Some wear components are self-lubricating.
  • a wear component may include a plurality of bores for receiving oil-impregnated graphite lubrication plugs which may lubricate the operating surface of the wear component during use.
  • a wear component may include a number of grease grooves provided in the operating surface for receiving lubrication from the plugs and/or from an external source. The plugs and/or grooves may therefore lessen any frictional forces acting on the operating surface. In any event, however, the operating surface inevitably wears down from repeated use and requires repair or replacement.
  • wear indicator grooves in the operating surface of the wear component.
  • Such grooves are typically linear from one side of the component to an opposite side thereof, with each groove of the component being of a uniform depth that is constant along the original operating surface. As the operating surface wears, each groove becomes shallower until such point that it disappears. When the groove is no longer present, the absence of the groove provides a visual indication to the operator that the wear has exceeded the initial depth of the groove and that the wear component should therefore be replaced.
  • a drawback of such grooves is that the operator may be unable to see a groove due to the angle of viewing and/or inadequate lighting conditions, giving the operator a false indication of wear.
  • Another drawback is that the operator is unable to monitor the rate of wear, since he or she is only able to see whether or not the groove is present. Therefore, the operator may be unable to conduct predictive planning with regard to a future need to repair or replace the wear component, absent performing the above-mentioned dismantling of the device to measure the wear component's thickness. In addition, if such a groove were to disappear between visual checks, the operator may be unable to discern how much additional wear has occurred after the groove disappeared.
  • a wear component for use in a manufacturing process includes at least one operating surface for absorbing a force generated during the manufacturing process and at least one wear indicator groove in the at least one operating surface and having a varying depth.
  • the at least one wear indicator groove may have at least one sloped base surface defined by an angle relative to the operating surface. For example, the angle may be between approximately 10 degrees and approximately 45 degrees.
  • the at least one wear indicator groove includes at least a first end having a first depth and a second end having a second depth, wherein the first depth is greater than the second depth.
  • the at least one wear indicator groove may include first and second legs angularly displaced from each other and defining an apex.
  • the depth of the at least one indicator groove may increase toward the apex.
  • the depth of the at least one indicator groove may decrease toward the apex.
  • the first and second legs are angularly displaced from each other by approximately 90 degrees.
  • the wear component includes a plurality of bores for receiving a plurality of lubrication plugs.
  • the wear component may further include a plurality of lubrication plugs, wherein each lubrication plug is received by a respective bore of the plurality of bores.
  • the at least one operating surface includes at least one of a bronze, a bronze-plated steel, a bronze alloy, or an aluminum-bronze alloy.
