摘要： 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.
摘要翻译：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。

摘要： The invention relates to a method for producing balls, especially for ball pivots, and to a ball element for two-part ball pivots. The balls according to the invention are produced by cold extrusion and subsequent grinding, using a micro-alloy carbon- manganese steel. The use of micro-alloy carbon-manganese steel allows to obtain balls having excellent strength and hardness already due to the cold shaping. It is not necessary to use a tempering step as required for the production of generic balls, which allows the use of less expensive materials, thereby considerably reducing production costs. The invention allows for a simple and inexpensive method for producing balls for two- part ball pivots while maintaining and/or increasing surface and material quality as well as strength and wear resistance. As a result, the complexity of the method is reduced and the problem of dents which can occur on the ball surfaces during tempering is removed. ® KIPO & WIPO 2007
摘要翻译：本发明涉及一种用于制造球，特别是球枢轴的球的方法，以及用于两部分球枢轴的球元件。根据本发明的球通过冷挤压和随后的研磨，使用微合金碳锰钢制成。使用微合金碳锰钢可以获得由于冷成型而具有优异的强度和硬度的球。不需要使用生产普通球所需的回火步骤，这允许使用较便宜的材料，从而显着降低生产成本。本发明允许用于制造用于两部分球枢轴的球的简单和便宜的方法，同时保持和/或增加表面和材料质量以及强度和耐磨性。结果，减少了该方法的复杂性，并且消除了在回火期间在球表面上可能发生的凹痕的问题。 ®KIPO＆WIPO 2007

摘要： 본 발명은 특히 볼-소켓 조인트를 위한 볼 및 2 부재 볼 저널을 위한 볼 소자의 제조 방법에 관한 것이다. 본 발명에 의한 볼의 제조는 냉간 압출 및 후속 연삭에 의해 행해지는데, 볼의 제조를 위해서는 미소합금 탄소-망간-강이 사용된다.
미소합금 탄소-망간-강의 사용에 의해 냉간 성형(변형)으로 이미 탁월한 강도 및 경도를 가진 볼이 얻어진다. 그래서 통상 기술에 따라 같은 종류의 볼을 제조하는 데에 필요했던 템퍼링 공정단계는 대체 없이 생략될 수 있고, 그래서 가격 유리한 재료가 사용될 수 있어 제조비용이 현저히 절감된다.
본 발명으로 특히 2 부재 볼 저널 용 볼이 보다 간단하고 보다 저렴하게 제조될 수 있고, 그와 동시에 표면 질과 재료 질 및 강도와 내마모성은 유지 내지 상승될 수 있다. 그 결과 볼의 제조 비용은 감소되고, 또한 템퍼링시 가끔 생기는 볼 표면 상의 덴트의 문제는 제거된다.

摘要： A heat exchanger comprises an as-cast combined header and tank having a header portion integral with a tank portion. The cast header and tank combination has a plurality of openings originally cast in the header portion of the combination and at least one opening originally cast in the tank portion of the combination for passage of coolant into or out of the cast header and tank combination. Tubes are received in and extends through the header portion openings, and resilient grommets seal the tubes to the header portion to prevent leakage around the tubes. In making the heat exchanger, there is provided an inner mold section and outer mold section corresponding respectively to the interior and exterior configurations of a desired combined header and tank having a header portion integral with a tank portion. The inner mold and outer mold sections are connected through the header and tank portion openings to support the inner mold section within the outer mold section and create a space therebetween corresponding to the configuration of the combined header and tank. The space is filled with molten metal and solidified to create the combined cast header and tank having the header portion integral with a tank portion. The outer mold section is removed and the inner mold section is removed from inside the cast header and tank through an opening in the header portion and/or through an opening in the tank portion. Following removal of the mold portions, the method may include inserting a tube from a heat exchanger core into an opening in the cast header portion and securing the tube therein.
