摘要：

利用数控渐进成形机床，对08钢板进行工具转动渐进成形，通过实验研究不同的工具转速和进给速度对08钢板的温升影响规律。结果表明，工具转动渐进成形相对于传统渐进成形可以显著地提升板料的温度，板料的温度升高主要是由于工具转动和板料之间的摩擦产热引起的。在进给速度一定时，板料所能达到的最高温度值会随着转速的增加而增加，在转速较低时转速增高对温度升高的影响比较大，在转速增大后转速增高对温度升高的影响变低；在转速一定时，板料所能达到的最高温度值会随着进给速度的增加而减少。

By the rotational tool in NC incremental forming machine, 08 steel sheet was formed gradually, and the influence rule of different rotational speeds and feed speeds on temperature rise of 08 steel sheet was investigated by experiment. The results show that the temperature of sheet metal can be increased significantly compared with traditional incremental sheet forming. The main reason is that the heat caused by the friction between the rotating tool and sheet metal. The maximum temperature of sheet metal increases with the rotational speed, while the feed speed remains unchanged. At a low rotational speed, the increase of rotational speed has a great influence on the temperature rise, but this effect becomes lower at a high rotational speed. The maximum temperature of sheet metal decreases with the increasing feed speed, while the rotational speed remains unchanged.
