The structure of xqc460tl-c bucket teeth studied in this paper has changed the symmetrical structure of the original bucket teeth, making the bucket teeth smooth and continuous wear surface, and reducing the wear resistance during excavation. At the same time, the bucket teeth are divided into two parts: the tooth tip and the tooth cavity. Because the wear of the tooth tip is large, the tooth tip is designed to be thicker, and the tooth cavity is thinner than the tooth tip to improve the service life of the bucket tooth. Low carbon and low alloy steel was used as bucket tooth material, adding a small amount of alloy elements, the mechanical properties of the material were significantly improved, the service life of the material was greatly improved, and the production efficiency and economic benefits were improved.
Under the pressure, the liquid die forging process can obtain uniform and fine microstructure, and the casting has high density. Compared with the traditional, shrinkage porosity and shrinkage cavity can be avoided without riser, and there is no sand inclusion. As an advanced forming technology, it has the advantages of less equipment investment, low product cost, resource saving, high material utilization and no waste discharge.
From the analysis of the above factors, it can be seen that the liquid forging technology has very important significance and advantages in economy, technology and improving product quality. Therefore, the production of liquid die forging bucket teeth is feasible.
