The invention discloses a manufacturing method for abrasion-resistant bucket teeth. The manufacturing method comprises the following steps that a bar is cut into sections, and the cut bar is placed on an automatic weighing device to be weighed; after weighed, the bar is fed into a heating furnace, heating treatment is conducted, and the bar is taken out of the furnace after heated; after heated, the bar is fed into a container under the forging temperature, and the container is used for calculating the mass and size of the bar in the unit; the container is conveyed into a pre-forging mold, pre-forging treatment is conducted, and the bar is fed into a finish forging mold after treatment, and finish forging forming is conducted; flanges of a semi-finished product are removed through polishing equipment; and the semi-finished product obtained after quenching treatment is conveyed into a tempering furnace, tempering insulation is conducted for 2 hours, then the product is taken out of the tempering furnace, and air cooling is conducted. Therefore, heat cutting is conducted directly under the forging temperature, cooling is not needed, time is saved, production efficiency is improved, thus product quality is ensured, in addition, the burr removing effect can be improved through the polishing equipment, and labor cost is reduced.
