[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model discloses a billet surface grinding device. When a formed billet is placed on a grinding platform for grinding, heating resistors on both sides of the billet generate heat which is transferred to the billet to provide temperature for the billet to keep it warm and prevent the billet's own heat from being lost quickly. At the same time, a hydraulic push rod pushes a movable plate to cover the top of the billet to prevent the heat generated by the heating resistor from being lost. When the heating resistor generates heat to keep the billet warm, a fan draws air and heat between the movable plate and the grinding platform, as well as heat emitted by the billet, into an external box, and then discharges the hot air from the heating resistor, so that the heat between the movable plate and the grinding platform is circulated, a heat-insulating space is realized, the heat loss of the billet in the heat-insulating space is slowed down, and repeated heating due to rapid heat loss of the billet during grinding is avoided.
