摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a β titanium alloy bolt at a low cost.
SOLUTION: Plated layers 22, 24 are formed on the outside surface 20 of a cylindrical blank 18 in plating processes P4, P5. After that, a bolt shape blank 50 is formed from the cylindrical blank 18 by cold forging in a cold forging process P7. Therefore, the β titanium alloy does not come into contact with dies 26, 34, 44 during cold forging because the plated layers 22, 24 are located between the dies 26, etc. and the cylindrical blank 18. As a result, the seizure of the cylindrical blank 18 and blanks 32, 42, 50 on the dies 26, etc. is preferably suppressed. Therefore, β titanium alloy bolts 10 can be manufactured at a low cost because the bolt shape blank 50 can be formed by cold forging.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of inexpensively manufacturing a stepped shaft component of titanium alloy.
SOLUTION: Plated layers 22 and 24 are formed on the surface 20 of a shaft material 18 in plating processes P4 and P5. Then, the shaft material 18 is forged into a stepped blank 50 in a cold or warm forging process P7. Since the plated layers 22 and 24 are interposed between a die 26 or 34 or 44 and the shaft material 18, the titanium alloy does not contact the die 26 or the like. This can satisfactorily restrain the shaft material 18 and the blank 32 or 42 or 50 from causing seizure with respect to the die 26 etc., whereby the stepped shaft blank 50 can be formed by forging so that the stepped shaft component 10 of titanium alloy can be manufactured inexpensively.

摘要： PROBLEM TO BE SOLVED: To provide a hole and a groove, having no burr, simply and in a short time by a method wherein a hole having diameter slightly smaller than a given diameter is formed through drilling and boring and finishing to a hole having a given diameter is effected by a finishing jig, and burrs generated during machining of a prepared hole are removed. SOLUTION: Prepared hole machining is effected by a drill having diameter smaller than a given size by 0.1-1.0mm. Namely, A hole 2 having diameter smaller than a given size by 0.1-1.0mm is formed. Finishing is then effected concentrically to a prepared hole 2 by an end mill 4 having a given hole diameter. This method, since a cutting work is effected in a specified cut depth from the inner surface of the prepared hole 2, removes burrs 1, formed in a state winding obliquely downward from a lower end part, from the root thereof. As noted above, a hole 3 freed from burrs is formed through combination of drilling works effected by an usual tool, such as a drill and the end mill 4.

摘要： PROBLEM TO BE SOLVED: To increase the productivity, by forming a guide rivet for the visually handicapped people at the bottom of a metallic body with a specified shape with an anchor like a bolt fixed thereto. SOLUTION: A guide rivet 1 is constituted of a pressed or forged metallic body 5 composed of a flat circular top face 2, a downward slant edge 3 provided in the periphery, and a recessed bottom face 4, and an anchor bolt 6 welded at the bottom plate 4. When the rivet 1 is fitted, the screw part of the bolt 6 is inserted in a hole made on a block on a side walk or the like and embedded in mortar placed in the hole in advance. When necessary, the body is shaped circularly to provide a protruded curved face. Or both ends are shaped to form a circularly protruded or recessed belt. Nonslip rugged face formed by a knurling or the like or a distinguishing mark made of a resin piece is formed on the surface of the body. In this way, the guide rivet can be produced in less processes with a favorable yield and the accuracy and durability can be improved and it can be lightened.

摘要： PURPOSE:To manufacture a modified cross sectional ring for which a cross section in the ring axial direction is modified with a plastic working without frequently exchanging the plastic working die. CONSTITUTION:On an inside diameter side roll 4 having the outside diameter smaller than the inside diameter of a ring-like raw material 3 having a modified cross sectional ring to be manufactured and the width larger than width in the ring axial direction of the modified cross sectional ring, the inside diameter side in the ring-like raw material 3 is abutted. Simultaneously, by relatively moving the ring-like raw material 3 in the ring axial direction while partially pressing the outside diameter side of the raw material 3 in the diameter direction of ring with an outside diameter side spinning roller 6 being in contact with a part of the outside diameter side of the raw material 3, the raw material 3 is formed to the modified cross sectional ring.

摘要： PROBLEM TO BE SOLVED: To provide a method for economically forming an O-ring attaching groove for plane sealing with the high machining precision. SOLUTION: In this method, with a pre-forming, a supplementary angle of an angle made with a plane to form an O-ring attaching groove and a wall face of the groove being formed with a preliminary forming is made as 60 to 85 deg., the maximum external diameter of the preliminary forming groove 5 is made larger than the external diameter of finish forming time, and the minimum internal diameter of the pre-forming groove 5 is made smaller than the internal diameter of the finish forming time, further, the volume of the preliminary forming groove 5 is made equal to the volume after finish forming, thus preliminary forming groove 5 is formed. Next, with finish forging, by shaping the pre-forming groove 5, the O-ring attaching groove for a plane sealing with the high machining precision can be formed economically. Both processes of the preliminary forging and the preliminary forming are executed with cold warm forging (cold forging or warm forging of executing by heating the material to the temperature of

摘要： PROBLEM TO BE SOLVED: To provide a cylindrical member to have stable necessary hardness and a high material yield and its manufacture. SOLUTION: A cylindrical member 34 has a large part 36 having diameter larger than those of first and second small parts 38 and 40 through up setting forging. Thereby, since the large part 36 formed through the forging is processed and cured through deformation occasioned by the forging, hardness of a surface part is stabilized to approximate Hv 300 or more high enough to ensure sealing ability. Simultaneously, since the large part 36 has diameter increased to a value higher than that of a material, i.e., a wire, through forging, a rod is cut to form the first and second small parts 38 and 40 and the diameter of the wire is decreased compared with a case that the relatively large part 36 is formed. A cut removing amount of the first and second small parts 38 and 40 is decreased.
