精密冲压汽车座椅调节器齿盘用冷轧钢板及其制造方法
摘要：
本发明涉及精密冲压汽车座椅调节器齿盘用冷轧钢板及其制造方法，解决现有精密冲压汽车座椅调节器齿盘用冷轧钢板尺寸精度低、球化率偏低、成本高、不适合高速精密冲压的技术问题。本发明提供的精密冲压汽车座椅调节器齿盘用冷轧钢板，其化学成分重量百分比为：C：0.15％～0.20％，Si≤0.05％，Mn：0.60％～0.80％，P≤0.018％，S≤0.008％，Alt：0.03%～0.07%，N≤0.0060％，余量为铁和不可避免夹杂。用于高速精密冲压制作汽车座椅调节器齿盘等零部件。
摘要（英）：

The invention relates to a cold rolled steel plate used for precision stamping car seat adjuster gear disks, and a preparation method thereof. The preparation method is used for solving technical problems of the prior art that the dimensional precision of conventional cold rolled steel plates used for precision stamping car seat adjuster gear disks is low, spheroidization rate is relatively low, cost is high, and the conventional cold rolled steel plates are not suitable for high speed precision stamping. The cold rolled steel plate used for precision stamping car seat adjuster gear disks contains, by weight, 0.15 to 0.20% of C, Si<=0.05%, 0.60 to 0.80% of Mn, P<=0.018%, S<=0.008%, 0.03 to 0.07% of Alt, N<=0.0060%, and the balance Fe and inevitable impurities. The cold rolled steel plate can be used for preparing parts such as car seat adjuster gear disks via precision stamping.
