<P>PROBLEM TO BE SOLVED: To provide a method of producing a hose metal fitting for simplifying a structure of a press machine 70. <P>SOLUTION: In the method, an article to be processed 12C is set in a die 71 using the press machine 70 and simultaneously a forming surface 77c of a split die 77 is set to be opposed to a spherical body part 12Cd, and a punch 79 is moved in an axial direction. Power to move in the axial direction of the punch 79 is converted into power to move the split die 77 in a perpendicular direction to the axial direction via a sloped surface 79c and a sloped surface 77b of the split die 77. Therefore, a sheet surface 12Df is formed in a flat part 12De, by pushing the spherical body part 12Cd with the forming surface 77c of the split die 77. <P>COPYRIGHT: (C)2011,JPO&INPIT |

<P>PROBLEM TO BE SOLVED: To provide a method of forming a valve guide which is light in weight and excellent in a heat resistance and a seizure resistance. <P>SOLUTION: A recess 2 having a large diameter is formed on a rod-like raw material 1 composed of an Al-based composite material by cold forging, and then the recess 2 is formed into a small hole 3 having the same diameter as a valve stem has by swaging work. After that, the material 1 is made into a cylindrical member by cutting the bottom part thereof, and the valve guide W with a flange 4 is obtained by cutting and shaving the outer circumference. Particularly if a groove 2a is formed in the inner circumference of the recess 2 after the cold forging, the groove 2a does not disappear by the swaging work and remains as an oil groove 3a. <P>COPYRIGHT: (C)2010,JPO&INPIT |

<P>PROBLEM TO BE SOLVED: To provide a cold forming method of a tapered piston pin with a central partition or without the partition by a single forming process. <P>SOLUTION: The method can eliminate secondary processes such as a machining process, an annealing process, a coating process, a secondary forming process and others not limited by these examples. The method includes steps of: cutting a metal bar into small columnar pieces; forming a first cavity in the small piece by extruding the small piece using a metal die; forming a second cavity in the small piece by extruding the small piece using an arbitrary metal die; forming the small piece into a hollow cylindrical piece by piercing the small piece; and forming the hollow cylindrical piece having a taper on the inner surface of each end of the hollow cylindrical piece by extruding each end of the hollow cylindrical piece using a metal die. <P>COPYRIGHT: (C)2008,JPO&INPIT |

PROBLEM TO BE SOLVED: To provide a flanged cylindrical metallic piece manufacturing method for reliably manufacturing the metallic piece by cold forging without cracks or shrinkage of a material.
SOLUTION: This manufacturing method comprises a recess forming step of forming a recess 39 at the end face of a stainless steel blank 30, and a flange forming step of protruding a flange 76 radially from an outer circumferential surface while deepening the recess 39 along the axial direction. In the flange forming step, the recess 39 is deepened along the axial direction by using an inner punch 63. An outer punch 65 which is concentrically located on the outer circumference of the punch 63 and separately moves, an inner counter punch 66 which faces the punch 63 and presses the end face 33 of a blank 38 during the forming, and an outer counter punch 69 which is concentrically located on the outer circumference and moves separately are individually moved in the axial direction when the punch 63 is moved. A ring-shaped cavity cv is formed between the punches 65 and 69, and the flange 76 is radially protruded on the inner side thereof.

PURPOSE: To manufacture a parts having an undercut formed to a prescribed hole diameter by a simple method without using a splitting die. CONSTITUTION: A blank for material 50a to be worked, positioned at the upper part from a tapered part 53 of the material 50a to be worked is upsetted by pressing with a sleeve punch 20. At the same time, the blank for material 50a to be worked, positioned in the vicinity of the tapered part 53 of the material 50a to be worked is ironing-worked with the shoulder part 12 of a die 10 and fuldged out and deformed. The blank for material 50a to be worked positioned in the vicinity of the tapered part 53 flows till abutting on the outer wall of a mandrel 30 so as to be squeezed in the diameter direction toward the axis of the material 50a to be worked and the hole part 52 in the material 50a to be worked has a gentle slope and reduced to the diameter d2. Since the blank for material 50a to be worked in the range shown with the L3 positioned to the lower part from the tapered part 53 of the material 50a to be worked is extruded frontward, this blank is extruded forward as it is to form the undercut shaped blind hole 42 having depth L4 corresponding to the depth L3. |

PURPOSE: To reduce by half of process number in a forging process, reduce the machining cost and improve the life of die.
CONSTITUTION: In order to forge a part with steps having a first small diameter part 2, a large diameter part 4 and a second small diameter part 3 on a lower step part, a middle step part and an upper step part in its axial direction with one process, an annular taper hole 28 which connects to the upper end of a first small diameter hole 27 of a lower die 20 and inclines so that the diameter is made larger facing toward the upper side is preliminarily formed, and an annular taper surface 46 which inclines so that the diameter is made smaller facing toward the upper side is preliminarily formed. Then, the taper hole 28 promotes the flow of raw material into the first small diameter part 2, and the taper surface 46 promotes the flow of raw material into the second small diameter part 3.

PURPOSE: To minimize work hardening of a material composing a skirt part consequently by forming the incorporated skirt part at one pass.
CONSTITUTION: In a method for manufacturing a tubular main body having a deformable incorporated skirt part, a tapered opening part penetrating an end wall 24 is formed without deforming a material of a locking shoulder part 44 arranged around a region 40 reduced in diameter by the process in which material is removed from the end wall 24. Thereafter, the material of the shoulder part 44 is upset forged in the axial direction so as to separate from a head end part 48 and so as to direct to a main region 20, an upset forged material 64 is moved radially outwardly in the region area 20 of a bore part, thereby forming the upset forged material 64 into the annular skirt part which is radially separated from the material of the main body encircling the material 64 from the circumference.
