摘要： PURPOSE:To produce easily a lightweight cam shaft having oil feed holes communicating with a hollow hole in the stage of casting the cam shaft by a centrifugal casting, by providing hole casting pins freely attachably and detachably in the cam parts and journal parts in a casting mold. CONSTITUTION:A casting mold 5 having the casting cavity part 5c corresponding to the shape of a cam shaft 4 is supported with a rotating mechanism 2 and a bearing 3 and is rotated at a high speed around the axial center. Hole casting pins 8 are beforehand mounted in the parts in the mold 5 corresponding to the cam parts 4a and journal parts 4b of the cam shaft. While the mold 5 is kept rotated at a high speed, molten metal for casting is charged therein and is solidified. A hollow part 4c is formed in the central part of the molten metal in the mold 5 by centrifugal force and if the pins 8 are removed, the oil feed holes communicating from the hollow part 4c are formed simply and easily in the cam parts 4a and journal parts 4b of the cam shaft 4.

摘要： PURPOSE:To obtain a cylindrical body of which surface has no generation of cracks by forming at least one of an external die and an intermediate die like a taper and pressing the intermediate die to a plastic material accomodated in the external die to make the material flow while applying compressive stress to the material. CONSTITUTION:Under the status that an intermediate die 13 is inserted into an external die 12, at least one of an external die side 12b and an intermediate die side 13a is formed like a taper so that the space between the side 12a and side 13a is gradually reduced in the direction of an opening 12a of the external die 12. When the intermediate die 13 is inserted and pressed after acoomodating a plastic material 4 into the external die 12, the material 4 moves upwards along the external die side 12b and the internal die side 13a by plastic fluidity. In this case, the circular sectional area of the material 4 is gradually reduced in the directon of plastic fluidity of the material 4, so that the material moves plastically while receiving compressive stress. This method prevents the internal and external walls 11a, 11b of the cylindrical body 11 from the generation of cracks after prodution.

CONSTITUTION:A leading-in part 2 of a rolled tooth form 3 is formed in a tapered shape, and on the other hand, a preliminary forming part 8 of a tapered tooth bottom face shape, in which a tooth bottom depth of one end part of the leading-in part 2 side becomes shallow gradually toward a tooth side face 5 of this one end part side, in reverse to a tooth top face 4 is formed continuously on a part of a tooth bottom face 7. The tooth form of this forming part 6 is set so that the rolled gear becomes a standard gear. The tooth form of the leading-in part 2 is set so as to become the same involute curve as the tooth form of a shaping part 6 in a border line to the shaping part 6, in case it is seen by a vertical section against the preliminary forming part 8. By this preliminary forming part 8, a rise of a thickness of the stock in the depth direction is detained and held down, and a gear or a spline having no defect can be rolled.

摘要： PURPOSE:To obtain a hollow shaft having high dimensional accuracy easily, by supplying the molten metal in a sleeve forcibly into the central part of a casting mold under rotation by the extruding operation of a plunger. CONSTITUTION:A sliding member 18 fixed to a sleeve 16 is brought into contact with the end part of a casting mold 15 to communicate the inside of the mold 15 and the inside of the sleeve 16 through an opening 15a for supplying molten metal and the member 18. Molten metal 30 is supplied through a charging port 19 into the sleeve 16 and a plunger 17 is advanced to supply the metal 30 into the mold 15. The metal 15 is formed into a hollow part by the centrifugal force developed by the rotation of the mold 15. The sleeve 16 is immediately detached from the mold 15 to prevent the adverse influence by abrasion, oscillation, etc. The hollow shaft having high dimensional accuracy is thus obtained easily.

摘要： PURPOSE:To obtain a uniform composite material by dispersing ceramic particles in a molten Al alloy before dispersing a foreign material such as activated carbon or graphite in the molten metal to prevent the separation of the foreign material due to floating or settling in the thoroughly melted state of the Al alloy. CONSTITUTION:Ceramic particles are dispersed in a molten Al alloy in a thoroghly melted state or a solid-liq. coexisting state. Powder of a foreign material such as activated carbon or graphite is then dispersed in the molten metal, and the molten metal is cast in the thoroughly melted state or the solid- liq. coexisting state of the Al alloy, preferably the thoroughly melted state or the solid-liq. coexisting state having such a solid phase fraction as to cause no trouble during casting. Since the ceramic particles inhibit the floating or settling of the foreign material, the foreign material can be dispersed uniformly. The preferred ceramic particles are AlO3 particles having a satisfactory wetting property to the Al alloy, yet particles of other oxide, nitride or carbide may be used.

摘要： PURPOSE:To obtain a light-weight and highly wear-resistant cam shaft by manufacturing a cam part and a shaft part by an aluminum alloy while dispersing granular or fibrous ceramic in said cam part. CONSTITUTION:A cam part 14 is formed by an aluminum alloy while granular or fibrous ceramic is dispersed in the cam part 14. The means of dispersion in the case of casting is such that a composite melt, in which granular or fibrous ceramic 11 is dispersed in an aluminum alloy melt 12, is cast in a mold 4. The shaft part is also formed by an aluminum alloy and is combined with the cam part by means of pouring, buldging, etc. Thereby, the cam shaft can be made light and have high wear resistance, also reducing the amount of wear of the mating member.

摘要： PURPOSE:To produce easily a hollow lightweight cam shaft having the high resistance to surface abrasion by charging a molten Al alloy mixed with reforming particles having the specific gravity larger than the specific gravity of the Al alloy into a casting mold for casting the cam shaft, and rotating the casting mold around the central axis thereof at a high speed. CONSTITUTION:A casting mold 5 having the casting cavity 5C corresponding to the shape of a cam shaft is supported with a rotating mechanism 2 and a bearing 3. A molten Al alloy mixed with reforming particles, such as Al2O3, TiN, BN, Si3N4, TiC or the like, having the specific gravity larger than the Al alloy for casting is charged into the cavity 5C and the mold 5 is rotated at a high speed with the mechanism 2. The reforming particles having the large specific gravity are scattered uniformly in the outside circumferential part of the cam shaft by centrifugal force, by which the surface of the cam shaft is improved in the resistance to abrasion and seizure. The Al alloy is solidified while the mold 5 is rotated, whereby the hollow part 4C is easily formed internally and the weight of the cam shaft is reduced.
