    • The invention relates to a cold forming method for producing ball journals comprising a ball region, a conical region and a threaded region for installation in ball-and-socket joints. According to said method, a ball journal blank (1) comprising a formed conical region (3) and cylindrical regions for the thread (2) and ball (5) are produced from a rod-shaped semi-finished bar material by extrusion. After the extrusion step, the ball region is subsequently formed by means of a rolling method in an additional production stage. At the same time, the threaded region can be given its final form. The production of the ball journal is thus achieved exclusively by cold forming and permits a significant increase in the production quantity per time unit in comparison with known methods in prior art. More economical types of steel can thus be used, as the cold forming method guarantees the sufficient durability of the ball journal.
    • 本发明涉及一种用于制造球轴颈的冷成型方法,包括球形区域,锥形区域和用于安装在球窝接头中的螺纹区域。 根据所述方法,通过挤出从棒状半成品棒材制造包括成形锥形区域(3)和用于螺纹(2)和球(5)的圆柱形区域的球轴颈坯料(1)。 在挤压步骤之后,随后在另外的生产阶段中通过轧制方法形成球形区域。 同时,可以给出螺纹区域的最终形式。 因此,与现有技术中的已知方法相比,球轴颈的制造仅通过冷成型实现,并且允许每时间单位的生产量显着增加。 因此,可以使用更经济的钢种,因为冷成型方法保证了球轴颈的足够的耐久性。

    • PURPOSE: A form rolling mold and a manufacturing method of a pin ferrule for a railway using the same are provided to manufacture a pin ferrule having high tensile strength and yield strength. CONSTITUTION: A form rolling mold comprises a base plane(100), first and second grooves(200,300), first and second side forming sills(400,500), and a protruded part(600). The first groove is formed between one and the other sides of the base plane. The second groove is formed between one and the other sides of the base plane to be separated from the first groove. The first side forming sill is formed in the opposite direction to the second groove, and the second side forming sill is formed in the opposite direction to the first groove. The protruded part is formed between the first and second grooves.
    • 目的:为了制造具有高拉伸强度和屈服强度的针式套圈,提供了一种成型轧制模具及其使用的铁路用套管的制造方法。 构成:成形轧制模具包括基面(100),第一和第二凹槽(200,300),第一和第二侧面成形框架(400,500)和突出部分(600)。 第一槽形成在基面的一侧和另一侧之间。 第二槽形成在基面的一侧和另一侧之间以与第一凹槽分离。 第一侧形成台阶形成在与第二槽相反的方向上,第二侧形成台阶沿与第一槽相反的方向形成。 突出部分形成在第一和第二槽之间。

    • PURPOSE: A method for manufacturing ball stud and ball stud product is provided to simplify manufacturing procedures by completing manufacturing of the product through a rolling process without cutting a ball stud blank. CONSTITUTION: A ball stud blank(100) comprises a head portion(10), a tapered portion(20) and a tail portion(30) formed integrally with each other, a hollow shaft(12) arranged within the heat portion, a hollow portion(14) arranged within the head portion of the ball stud blank so as to improve sphericity a waveform surface(16) formed at the inner surface of the hollow portion so as to improve illumination of the surface of the sphere. A method comprises the steps of forming at the same time the neck portion, and the tail portion by using a rolling; and forming an overall sphericity of the head portion by allowing for a volume shift from a high volume toward a low volume throughout the hollow axis and the hollow portion of the ball stud blank.
