Piston rod forging method

The invention belongs to the field of mechanical forging, and particularly relates to a piston rod forging method which comprises the following steps: (1) heating through a heating furnace: heating a workpiece to 870-890 DEG C at a heating rate of 30-40 DEG C/h, keeping for 30 minutes, then heating to 1050-1100 DEG C at a heating rate of 60-80 DEG C/h, keeping for 30 minutes, and then normally air-cooling to 950-1000 DEG C; the method has the beneficial effects that the production efficiency of the piston rod is improved, the machining workload is reduced, cutters and raw materials are saved, the product percent of pass is increased, the productivity is improved, and the performance of the piston rod is better. 本发明属于机械锻造领域，更具体地说，本发明涉及一种活塞杆锻造方法，包括如下步骤：（1）通过加热炉加热：对工件以30-40℃/h的升温速率升至870-890℃，保持30min，然后60-80℃/h的升温速率加热至1050～1100℃，保持30min，再正常空冷至950～1000℃；有益效果：提高了活塞杆的生产效率，也减少了机加工的工作量，节省了刀具和原材料，增大了产品合格率，提高了生产率，活塞杆性能更好。
