专利汇可以提供Composite wire drawing die专利检索,专利查询,专利分析的服务。并且Composite wire drawing die construction is described in which a centrally-located mass of diamond, cubic boron nitride or a polycrystalline mixture thereof defines at least the throat of the wire drawing hole, the mass being flanked or girded by at least one mass of metal bonded carbide that is directly bonded thereto. The composite is readily ground into the form of a solid of revolution. In the preferred construction (for dies for drawing 0.008 inches diameter wire and larger) a composite assembly includes at least one high strength metal ring that is press fitted around a composite body or sub-assembly comprising a polycrystalline mass of diamond girded by a metal-bonded carbide jacket.,下面是Composite wire drawing die专利的具体信息内容。

  • 2. The wire drawing die as recited in claim 1 wherein the inner mass is predominately polycrystalline diamond.
  • 3. The wire drawing die as recited in claim 1 wherein the inner mass is predominately polycrystalline cubic boron nitride.
  • 4. The wire drawing die as recited in claim 1 wherein the inner mass is in a generally cylindrical form and the carbide mass is in the form of a jacket therearound.
  • 5. The wire drawing die as recited in claim 4 wherein the composite is in the shape of a truncated cone.
  • 6. The wire drawing die as recited in claim 1 wherein the composite is press fitted into a high tensile strength annular body.
  • 7. The wire drawing die as recited in claim 6 wherein the outer wall of the composite is in a state of permanent compressive stress of at least about 10,000 psi.
  • 8. The wire drawing die as recited in claim 6 wherein the annular body is made of metal.
  • 9. The wire drawing die as recited in claim 1 wherein the composite is in the shape of a truncated cone.
  • 10. The wire drawing die as recited in claim 1 wherein the inner mass is both flanked and girded by the mass of metal bonded carbide.
