小模数花键轴的冷滚轧工艺具有高效率、无切屑、被加工零件的尺寸一致性好、滚轧轮寿命长等一系列优点,它尤其适用于大批量生产。通常采用双滚轧轮的加工型式(见图1)。两滚轧轮的尺寸相同,并由机床传动链保持以同向等速旋转。机床的一滚轧头固定,另一滚轧头靠油缸作径向进给运动,以此将工件滚轧成形。现介绍滚轧轮的设计方法。 Small modulus spline shaft cold rolling process has a series of advantages of high efficiency, no chip, the size uniformity of the processed parts, long life of the rolling wheel, which is especially suitable for mass production. Usually double-wheel processing mode (see Figure 1). Two rolling wheels of the same size, and kept by the machine tool chain to rotate at the same speed. A rolling head of the machine is fixed, and the other rolling head is driven radially by the oil cylinder to form the workpiece by rolling. Now introduce the design of rolling wheel.
