Definitions

  • the present invention relates to a spinning forming method of processing a plate, according to the preambles of claims 1 and 5.
  • the processing tool while the processing tool is being pressed against the plate at a constant axial sending speed (a movement speed of the processing tool in a direction along a rotation axis of the plate), the processing tool is moved at a constant radial traveling speed (a movement speed of the processing tool in a direction vertically away from the rotation axis of the plate) from an inside edge of the formation target region of the plate toward an outside edge of the formation target region. Immediately after the processing tool reaches the outside edge of the formation target region, the processing tool is separated from the plate.
  • a constant axial sending speed a movement speed of the processing tool in a direction along a rotation axis of the plate
  • a constant radial traveling speed a movement speed of the processing tool in a direction vertically away from the rotation axis of the plate
  • a depression (a press mark by the processing tool) corresponding to the shape of the processing tool is formed at a position the plate from which position the processing tool is separated.
  • An object of the present invention is to provide a spinning forming method capable preventing the formation of the press mark by the processing tool.
  • a spinning forming method is a spinning forming method of forming a formation target region of a plate into a tapered shape by using a processing tool while rotating the plate, the spinning forming method including: moving the processing tool from an inside edge of the formation target region to an outside edge of the formation target region while pressing the processing tool against the plate, characterized by rotating the plate in a state where a position of the processing tool is fixed at the outside edge.
  • the processing tool stands by at the outside edge (i.e., a forming finish point) of the formation target region. Therefore, the formation of the press mark by the processing tool can be prevented.
  • a spinning forming method is a spinning forming method of forming a formation target region of a plate into a tapered shape by using a processing tool while rotating the plate, the spinning forming method comprising: moving the processing tool from an inside edge of the formation target region to an outside edge of the formation target region while pressing the processing tool against the plate, characterized by reducing an axial sending speed and radial traveling speed of the processing tool when the processing tool is located in a vicinity of the outside edge.
  • the plate is slowly processed in the vicinity of the outside edge (i.e., the forming finish point) of the formation target region. Therefore, the formation of the press mark by the processing tool can be prevented.
  • the pressing of the processing tool against the plate may be performed while locally heating a portion of the plate, the portion being located on a same circumference as a portion of the plate against which portion the processing tool is pressed. According to this configuration, the portion of the plate against which portion the processing tool is pressed can be processed more intensively than a case where the plate is not heated and a case where the plate is entirely heated. Therefore, the operation of the processing tool for obtaining a desired shape is facilitated.
  • the processing tool may be a forming roller having a trapezoidal cross section that decreases in diameter in a direction away from a rotation axis of the plate, and the pressing of the forming roller against the plate may be performed in a state where a large-diameter portion of the forming roller is in point contact with the plate, and the forming roller is kept in such a posture that an angle between a side surface of the forming roller and a plane orthogonal to the rotation axis of the plate is not less than 1° and not more than 30°. According to this configuration, warp-up of a portion of the plate which portion is located outside the portion against which the processing tool is pressed can be restricted by the side surface of the forming roller.
  • the pressing of the processing tool against the plate may be performed in a state where a portion of the plate against which portion the processing tool is pressed is floating. According to this configuration, it is unnecessary to use a shaping die (mandrel) which has been often used in conventional spinning forming methods, so that the manufacturing cost can be reduced.
  • the present invention can prevent the formation of the press mark by the processing tool.
  • Fig. 1 is an explanatory diagram of a spinning forming method according to a preferred embodiment of the present invention.
  • This spinning forming method is a method of forming a formation target region R (see Fig. 2A ) of a plate 1 into a tapered shape by using a processing tool 3 while rotating the plate 1.
  • the plate 1 is, for example, a flat circular plate.
  • the shape of the plate 1 may be a polygonal shape or an oval shape.
  • the plate 1 does not necessarily have to be entirely flat.
  • the thickness of a center portion of the plate 1 may be smaller or larger than the thickness of a peripheral portion of the plate 1, and the plate 1 may be entirely or partially processed into a tapered shape in advance.
  • a material of the plate 1 is not especially limited and is, for example, a titanium alloy.
  • the plate 1 is fixed to a rotating shaft 2.
  • a center line of the rotating shaft 2 corresponds to a rotation axis 10 of the plate 1.
  • the rotation axis 10 of the plate 1 may be parallel to a vertical direction, may be parallel to a horizontal direction, or may extend in an oblique direction.
  • the rotating shaft 2 is rotated by a rotating mechanism (not shown).
  • a shaping die (mandrel) is not disposed at the rotating shaft 2. Only the center portion of the plate 1 is supported by the rotating shaft 2 not only before the start of the spinning forming but also during the spinning forming. To be specific, below-described pressing of the processing tool 3 against the plate 1 is performed in a state where a portion of the plate 1 against which portion the processing tool 3 is pressed is floating. According to this configuration, it is unnecessary to use the shaping die (mandrel) which has been commonly used in conventional spinning forming methods, so that the manufacturing cost can be reduced. However, the shaping die (mandrel) may be disposed at the rotating shaft 2, and the portion of the plate 1 against which portion the processing tool 3 is pressed may be supported by the shaping die during the spinning forming.
  • the processing tool 3 is moved from an inside edge (i.e., a forming start point) Rs of the formation target region R toward an outside edge (i.e., a forming finish point) Re of the formation target region R while being pressed against the plate 1.
  • the processing tool 3 is moved in a direction along the rotation axis 10 of the plate 1 at a specific axial sending speed corresponding to each position on the plate 1 to be pressed against the plate 1.
  • the processing tool 3 is moved in a direction vertically away from the rotation axis 10 of the plate 1 at a specific radial traveling speed corresponding to each position on the plate 1.
  • used as the processing tool 3 is a forming roller 30 that follows the rotation of the plate 1 to rotate.
  • the processing tool 3 is not limited to the forming roller 30 and may be, for example, a spatula.
  • the forming roller 30 has a trapezoidal cross section that decreases in diameter in a direction away from the rotation axis 10 of the plate 1.
  • the forming roller 30 includes: a large-diameter bottom surface located closer to the rotation axis 10; a small-diameter top surface located at an opposite side of the rotation axis 10; and a tapered side surface 31 connecting the bottom surface with the top surface.
  • an annular corner portion between the side surface 31 and the bottom surface is a large-diameter portion
  • an annular corner portion between the side surface 31 and the top surface is a small-diameter portion.
  • a forming roller having a different cross section such as a diamond cross section or a long round cross section
  • the pressing of the forming roller 30 against the plate 1 is performed in a state where: the large-diameter portion of the forming roller 30 is in point contact with the plate 1; and the forming roller 30 is kept in such a posture that an angle ⁇ (see Fig. 2A ) between the side surface 31 of the forming roller 30 and a plane (i.e., a plane parallel to the plate 1) orthogonal to the rotation axis 10 of the plate 1 is not less than 1° and not more than 30°.
  • the pressing of the processing tool 3 against the plate 1 is performed while a portion of the plate 1 is locally heated by a heater 4, the portion being located on the same circumference as the portion against which the processing tool 3 is pressed.
  • This expression "on the same circumference” denotes that the portion against which the processing tool 3 is pressed and the portion heated by the heater 4 are located within a ring-shaped range defined around the rotation axis 10 of the plate 1 and having a certain width.
  • the portion heated by the heater 4 may be located within a range centering the portion against which the processing tool 3 is pressed, the range corresponding to ⁇ 10% of a distance from the rotation axis 10 of the plate 1 to the portion against which the processing tool 3 is pressed.
  • the heater 4 is disposed at an opposite side of the processing tool 3 across the plate 1 so as to heat the plate 1 from a rear side.
  • the heater 4 may be disposed at the same side as the processing tool 3 relative to the plate 1 so as to heat the plate 1 from a front side.
  • the heater 4 is desirably a high-frequency induction heater including a coil portion to which an alternating voltage having a high frequency of 5 k to 400 kHz is applied.
  • the coil portion desirably extends in a rotational direction of the plate 1 and has a doubled circular-arc shape facing the plate 1 so as to be able to perform local heating of the plate 1 continuously in the rotational direction of the plate 1.
  • a gas burner may be used as the heater 4.
  • Fig. 3 shows a state where the processing tool 3 is pressed against the plate 1 immediately before the spinning forming finishes.
  • a depression a press mark 11 by the processing tool 3
  • the processing tool 3 stands by at the outside edge Re of the formation target region R. Therefore, as shown in Fig. 5 , the formation of the press mark 11 (see Fig. 4 ) by the processing tool 3 can be prevented.
  • a portion of the plate 1 which portion is located outside the portion against which the processing tool 3 is pressed may warp up toward the processing tool 3.
  • the forming roller 30 having the trapezoidal cross section is used, and the posture of the forming roller 30 is kept as in the present embodiment. With this, the warp-up of the outside portion of the plate 1 can be restricted by the side surface 31 of the forming roller 30.
  • the processing tool 3 stands by when the processing tool 3 reaches the outside edge Re of the formation target region R.
  • the axial pressing speed and radial traveling speed of the processing tool 3 may be reduced in the vicinity of the outside edge Re.
  • This expression "the vicinity of the outside edge Re” denotes a range which spreads from the outside edge Re inward to a portion corresponding to one fifth of the formation target region R as an upper limit and may be set arbitrarily.
  • the axial sending speed and radial traveling speed of the processing tool 3 may be reduced to not more than half the axial sending speed and radial traveling speed of the processing tool 3 before the processing tool 3 reaches the finish close point.
  • the plate 1 is slowly processed in the vicinity of the outside edge Re of the formation target region R. Therefore, as shown in Fig. 5 , the formation of the press mark 11 (see Fig. 4 ) by the processing tool 3 can be prevented.
  • the pressing of the processing tool 3 against the plate 1 may be performed in a state where the plate 1 is entirely heated or a state where the plate 1 is not heated instead of a state where the plate 1 is locally heated.
  • the portion of the plate 1 against which portion the processing tool 3 is pressed can be processed more intensively than the case where the plate 1 is not heated or the case where the plate 1 is entirely heated. Therefore, the operation of the processing tool 3 for obtaining a desired shape is facilitated.
