摘要： To sufficiently secure the width dimension, strength and rigidity of the rack teeth 10, and to realize the light weight construction and the manufacturing method of the rack 8, the rack teeth 10 is formed by plastic working on one side surface in the radial direction of part in the axial direction of a rod unit 9 having a circular cross-sectional shape, and the curvature radius of the portion which is separated in the radial direction from the portion where the rack teeth 10 is formed, is made greater than that of the cross sectional shape of the outer surface of the axial remaining portion of the rod unit 9. For this purpose, as shown in (A) to (B), while a portion in the circumferential direction of part in the axial direction of a material 13 is compressed, the remaining portion in the circumferential direction of this part in the axial direction is formed into a partial cylindrical surface 17 whose curvature radius is larger than that of the outer surface of the material 13, to form an intermediate material 20. Then, as shown in (C) to (D), the rack teeth 10 are formed on the circumferential portion of the axial part of the intermediate material 20. At last, as shown in (E) to (F), sizing is performed to obtain the rack 8.

摘要： When a punch is downwardly pressed, an inner circumferential surface of a first rack blank bites into a top surface of a second rack blank. A blank material upwardly flows due to a reaction force and is used to form rack teeth. Thus, a filling degree of the teeth with the material is enhanced. At the time when the forming of the rack teeth is finished, a gap is left between the inner circumferential surface of the first rack blank and the outer circumferential surface of the second rack blank. Thus, a die is not put into a sealed condition. Consequently, a forming load is small so that the lifetime of the die is lengthened. Also, the top surface of the second rack blank bites into a bore hole portion of the first rack blank so that the first rack blank and the second rack blank are joined together. Accordingly, the rigidity of the entire rack teeth is increased.
摘要翻译： 当向下按压冲头时，第一齿条坯料的内圆周表面咬入第二齿条坯料的顶表面。 空白材料由于反作用力而向上流动并用于形成齿条齿。 因此，增加了与材料的牙齿的填充度。 在齿条齿的形成结束时，在第一齿条毛坯的内周面和第二齿条毛坯的外周面之间留有间隙。 因此，模具不会被置于密封状态。 因此，成形载荷小，使得模具的寿命延长。 此外，第二齿条坯料的顶面咬入第一齿条毛坯的钻孔部，使第一齿条毛坯和第二齿条毛坯接合在一起。 因此，整个齿条齿的刚度提高。
