Processing Method For Spline Shaft
2021-03-26Spline processing method] rl] Spline shaft url] b] processing method is a lot. Mainly used in the cutting process such as hobbing, milling and grinding, it can also be used in the cold deformation, cold rolling and other plastic deformation processing methods.
Rolling method: It is processed by the spline hob on the spline shaft milling machine or hobbing machine according to the forming method. This method has high productivity and precision and is suitable for mass production.
2. Milling method: directly milling the inter-tooth profile with a special forming cutter on the universal milling machine, and milling the teeth with the indexing head. If the milling cutter is not used, the two milling cutters can also be used to simultaneously mill one tooth. On both sides, after milling by tooth, use a disc cutter to slightly trim the bottom diameter. The milling method has low productivity and precision, and is mainly used for processing spline shafts with outer diameter centering and roughing before hardening in single-piece small batch production.
3. Grinding method: Grinding spline flank and bottom diameter on a spline shaft grinding machine with a forming grinding wheel, suitable for processing hardened spline shafts or splines with higher precision, especially with inner diameter centering splines axis.
4. Cold play: on a special machine. The two heads symmetrically arranged outside the circumference of the workpiece, with the indexing rotary motion of the workpiece and the axial feed for a constant speed ratio of high-speed rotation, the workpiece per revolution of 1 tooth, the forming wheel on the head is on the tooth groove of the workpiece Hammering once, under the continuous high-speed, high-energy motion hammering, the surface of the workpiece is plastically deformed into splines. The accuracy of cold punching is between milling and grinding, and the efficiency is about 5 times higher than milling. Cold hitting can also improve material utilization. The above introduction is a detailed explanation of the spline shaft processing method.
