摘要： In a die forging process, projections (4a) are formed on an inner circumference thereof. The projections (4a) are inserted into holes (46) provided in a disc plate (45). The projections (4a) are crushed by a punch 49 so that the disc plate (45) is securely fixed on an inner circumference of the annular gear 41. The process can eliminate a cutting and an electric welding to shorten a manufacturing time.

摘要： A process for manufacturing toothed parts having a tooth profile on a portion of their outline. The process utilizes a press machine having top and bottom die sets with stock interposed therebetween at uniform intervals in sequence with the vertical operation of the press machine. The process includes a first step wherein a center hole is stamped in said stock and, a second step wherein a window hole corresponding to the exterior peripheral tooth profile is stamped in said stock using the center hole as a reference, a third step wherein a tooth profile having a tooth width greater and a tooth height lower than the final tooth profile is rough-formed on one side of said window hole, and a fourth step wherein the exterior periphery of said rough-formed toothed part undergoes stamping and ironing operations concurrently with the processing of the final tooth profile.

摘要： A method for manufacturing a camshaft by inserting a hollow shaft 3 made of steel into an axial hole 400 of a cam lobe 4 made of a sintered alloy, by expanding the hollow shaft 3 by inserting a mandrel 1 into the hollow shaft 3, and by joining and fixing the expanded hollow shaft 3 and the cam lobe 4 while avoiding the constriction that might otherwise be caused by the retraction of the mandrel 1 inserted, of the expanded hollow shaft 3. The method includes an expanding step using a diverging long face 200, which is so formed on the leading head of the mandrel 1 as to diverge at an angle of about 8 to 30 degrees with respect to the axis toward the trailing end, and a bulging portion 2 formed to lead from the diverging face 200; and an expanding step using the bulging portion 2 of the mandrel 1 and a converging short face 201 which is formed so as to lead from the bulging portion 2 and to converge at an angle of about 8 to 30 degrees with respect to the axis toward the trailing end.

摘要： The present invention discloses a manufacturing process whereby a spur gear is cold-press molded. By means of the invention a pre-punched workpiece is loaded on a counter which is admitted to a bore in a female die having a chamfer at its inlet, pressure is applied on the workpiece through the bore in the female die by means of a punch when pressure is increased from below so as to lift the counter from the counter plate, a primary product is formed by means of causing said workpiece to descend so as to transit the chamfer, extracting said primary product from the female die and reversing its orientation top to bottom, and repeating the identical process once again.
