In the steps 3 and 5 of the invention, the heating mechanism is preheated, so that the temperature of the heating mechanism is enough to soften the surface of the workpiece when the workpiece passes through the heating mechanism, further the surface hardness of the workpiece is reduced, and the subsequent polishing is easier to remove burrs on the surface of the workpiece.
In step 6 of the invention, the heated workpiece pre-grinding mechanism is contacted, so that the surface of the workpiece is primarily ground when the workpiece passes through the pre-grinding mechanism, part of burrs on the surface of the workpiece are ground before the workpiece is finely ground, then the workpiece which is primarily ground is finely ground in step 7, the burrs on the surface of the workpiece are thoroughly ground under the action of multiple times of grinding, and in the grinding process, step 8 continuously sprays cutting fluid to the grinding mechanism, so that the abrasion of the first grinding roller and the second grinding roller in the grinding process is reduced, and simultaneously the heat generated by friction is reduced.
In the step 9 of the invention, the first cylinder discharges hot air in the case into the heating mechanism, the second cylinder discharges cold air outside the case to the polished workpiece, so that the hot air in the case is discharged into the heating mechanism and recycled to improve the heating efficiency of the heating mechanism, thereby reducing energy consumption caused by heat loss of the heating mechanism, and metal powder left on the polished workpiece surface is taken away by airflow, so that the workpiece is kept clean, and meanwhile, because the air blown to the workpiece is the cold air outside the case, the workpiece can be cooled, and the workpiece surface is prevented from being deformed due to the fact that the high-temperature softening state is kept for a long time.
According to the invention, the workpiece can be continuously polished only by continuously placing the workpiece on the first conveyor belt without repeatedly dismounting the workpiece, so that the polishing efficiency is greatly improved.
Further, the concentration of the water-based cutting fluid is preferably 3% to 5%. The friction between the polishing mechanism and the workpiece is more severe during fine processing, so that the concentration of the water-based cutting fluid is increased, and the heat generated during friction is better reduced.
Further, the first conveyor belt is slower than the second conveyor belt, the first conveyor belt is preferably 0.5m/s to 1.0m/s, and the second conveyor belt is preferably 1.0m/s to 1.5 m/s. When the workpiece passes through the first conveyor belt, the belt speed is low, so that the workpiece is slow when passing through the pre-polishing mechanism and the polishing mechanism, the workpiece is sufficiently polished, and the belt speed of the second conveyor belt is high, so that the workpiece can be rapidly conveyed out of the case to be polished.
furthermore, the temperature in the heating mechanism is preferably 650-700 ℃. The temperature of 650-700 ℃ enables the surface of the workpiece to be softened without softening the whole workpiece.
