Definitions

  • the main object of the present invention is therefore to manufacture economically, and without defects, discs or metal objects from wire, in which internal faults caused by buckling are eliminated.
  • a method for manufacturing discs or other metal parts of circular or similar cross section from metal wires cut into portions of a given length wherein each portion is inserted individually along its longitudinal axis into a prismatic housing in a first matrix and is subjected to a first press forging in this first matrix, forming a prismatic blank; the prismatic blank being then withdrawn from the first matrix and inserted axially into a cavity, having the cross-sectional shape of the object to be produced and provided in a second matrix, the blank thus placed into the second matrix being then subjected to a final press forging to produce the final shape of the fabricated part.
  • the prismatic housing of the first matrix has a cross section in the shape of an equilateral triangle and its sides are tangents of the cylindrical piece of wire along three generating lines offset by 120 relative to each other.
  • the cavity of the second matrix is a revolutional cylindrical shape.
  • FIG. 1 shows a diagrammatic view of a reel of wire and a cutting apparatus
  • FIG. 2 shows a small wire cylinder before insertion into a first matrix
  • FIG. 3 is a plan view of the small wire cylinder in the first matrix
  • FIG. 4 is a sectional view along line IVIV of FIG. 3;
  • FIG. 5 shows a blank after removal from the first matrix, haVing undergone a forging operation
  • FIG. 6 is a plan view of the blank illustrated in FIG. 5 after second matrix havin under oneafor in o eration.
  • a wire reel I is mounted on a drum; the wire lb is unreeled and runs into a cutting device Ia which cuts it into pieces, thus forming small wire cylinders, such as 2.
  • These cylindrical pieces are gripped individually by pincers (not shown) and inserted axially into a housing 3 of a first matrix 4.
  • This housing has a prismatic triangular shape, the cross section of the housing being an equilateral triangle.
  • the surfaces of the housing are tangents relative to the cylinder 2 along three generating lines offset relative to each other by In view of this arrangement, the cylinder 2 is retained along its generating lines and can therefore easily resist buckling.
  • the cylinder When forging is effected along the arrow X, the cylinder is flattened and is deformed in three directions Y offset at 120 relative to each other, and assumes the triangular prismatic shape of the housing 3.
  • the result is a prismatic, triangular blank 2a which is removed from the housing 3 and transported by pincers not shown, into a cylindrical revolutional cavity 7 of a second matrix 5.
  • This cavity is so chosen that its cross section circumscribes the cross section of the blank 2a.
  • the invention applicaBle to the fabrication of discs, may be used for manufacturing pastils, rivets and generally other small objects of circular or near circular cross section. In certain cases, it may be necessary to make certain adaptations, without, however, thereby departing from the principle of the invention.
  • a method of manufacturing metallic blanks from metal wire consisting of the steps of:
