    摘要： A novel forging process by which forged steering knuckles having improved toughness are produced. The method comprises splitting an elongated steel billet over the web of a buster die to provide material for the support legs by pressing the billet against the web with a mating die having a cavity which permits controlled flow of the hot steel in the opposite direction to produce a boss from which the spindle will be made. The saddle-shaped blank thus produced is layed on its side within a blocking die and pressed in a direction normal to said first flow of material to block the knuckle blank out and move excess material into a margin of peripheral flashing. A third and then a final fourth die pressing step gives the steering knuckle forging its final dimensions and trims the flashing from the blocked out blank.

    摘要翻译： 制造出具有改善韧性的锻造转向节的新颖锻造工艺。 该方法包括将细长的钢坯在破碎模具的腹板上分开，以通过使具有空腔的配合模具将坯料压靠在腹板上来为支撑腿提供材料，该模具允许热钢沿相反方向受控流动以产生 主轴将由主轴制成。 这样制成的马鞍形坯料在其封闭模具的侧面上，并沿垂直于所述第一材料流动的方向被压制，以阻挡转向节坯料，并将多余的材料移动到周边闪光的边缘。 第三次，然后是最后四次模压步骤，使转向节锻造其最终尺寸，并从遮盖的坯料上修整闪光。

    摘要： A method for manufacturing a combined driveshaft tube and yoke assembly includes the initial step of providing a workpiece having a first portion defining a first wall thickness and a second portion defining a second wall thickness that is different from the first wall thickness. The first and second portions can be first and second sections that are separate from one another and joined together. Alternatively, the first and second portions can be formed integrally with one another. A pair of yoke arms having respective openings therethrough are formed in the first portion of the workpiece to provide a combined driveshaft tube and yoke assembly. A bearing bushing may be disposed in each of the openings. Alternatively, the yoke arms can have respective flanged openings formed therethrough.

    摘要： A method for producing dimensionally accurate rocker arms formed with a roller-receiving portion at one end. The method of the invention produces rocker arms which have a roller-receiving, fork-like portion at one end of the rocker arm body for receiving a roller contacting a cam. The method uses the steps of inserting between the opposed inner surfaces of the roller-receiving portion an insert jig having a parallel surface and a slant surface inclined inwardly of the jig by a predetermined angle from the parallel surface; placing a pressing jig on an outer surface of the roller-receiving portion, the surface of the pressing jig to be contacted with the outer surface of the roller-receiving portion having a parallel surface and a slant surface inclined outwardly of the pressing jig by a predetermined angle from the parallel surface; and applying pressure to the pressing jig to thereby press the inner surfaces of the roller-receiving portion against the surfaces of the insert jig. The predetermined angles of the insert jig and the pressing jib are respectively in the range of from about 2.degree. to about 4.degree..
