Machining After Final Metal-deforming (e.g., Grinding To Size) Patents (Class 72/340)
  • Patent number: 11565301
    Abstract: A metal member manufacturing method according to one form of this disclosure is a method of manufacturing a metal member that is thinner at some portions than at other portions. The method includes a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form a raised portion in the other surface, and a cutting step of moving a cutting blade along the other surface to cut off the raised portion by shaving. In the formation step, the raised portion is formed such that the area of a cross-section of the raised portion that is parallel to a moving direction of the cutting blade and perpendicular to the other surface decreases toward an end of the raised portion on a rear side in the moving direction of the cutting blade.

  • Patent number: 8087279
    Abstract: A method and apparatus for manufacturing a legged annular member. In one aspect, a work member is formed from a ring-like raw material, and has an annular part and an outer wall part, which is formed from a leg part and a connecting part. The connecting part is removed from the work member to form an intermediate legged annular member having an annular part and a leg part. An inner diameter of the leg part of the intermediate legged annular member is expanded while a burr is removed to form a carrier, which serves as a legged annular member. Therefore, the number of manufacturing processes until completion of the carrier can be reduced, compared to performing separate processes to expand the diameter of the leg part and remove the burr. Thus, it is possible to shorten the period of time needed for completion of the carrier.

    Abstract: When manufacturing a ring and a pendant from a single metal plate, the number of the twist is determined so that a predetermined feature pattern may occurs regardless size on the surface of a male ring and a female ring. The feature pattern depends on the method of the laminating of two or more metal plates, the kind of metal plate, thickness, etc. for example. The number of times of twist concerned is determined based on these information.
