The invention discloses a machining process for a rotating shaft of a seat angle adjuster. The machining process comprises the following steps that: blanking is performed; intermediate surface treatment is performed; cold extrusion is conducted, so that tooth shapes are extruded on the periphery of a workpiece; machining is conducted, specifically, part of the inner hole and periphery of the workpiece are machined; heat treatment is performed; grinding is performed; and blanking, cold extrusion, machining and grinding are carried out in sequence. With the machining process of the invention adopted, the size and form and location tolerance of a product can be met; the performance requirement of the product can be met; poor appearance risks such as collision-caused damage in a machining process can be reduced; a high-precision special-shaped structure part is formed by one-time extrusion of a forming die, and therefore, the machining time of the product is shortened, and the size stability of the product is ensured; and therefore, the machining quality of the rotating shaft of the seat angle adjuster is ensured, and the requirements of customers are met.

    本发明公开了一种座椅调角器转轴的加工工艺,包括以下步骤:下料;中间表面处理;冷挤压加工,在工件外周挤压出齿形;机加工,加工工件的部分内孔和外周;热处理;磨削加工;下料、冷挤压加工、机加工、磨削加工依次进行。本发明提出的座椅调角器转轴的制造工艺,既满足产品尺寸及形位公差,又可满足其性能要求,还可减少了加工过程碰伤等外观不良风险。高精度异形结构部分采用成形模一次挤压而成,即缩短了产品加工时间,也保证了产品尺寸的稳定性,从而保证座椅调校器转轴的加工质量,满足客户需求。
