With the continuous upgrading and improvement of mechanical equipment, more and more industries are turning to these advanced machines to assist in operations. Among them, excavators are one of the most practical and widely used. The bucket teeth, being a critical working part of an excavator, play a vital role. If the bucket teeth malfunction, a significant portion of the machine's functionality becomes unusable. Therefore, maintaining excavator bucket teeth is of great importance.

High manganese steel or low-carbon alloy steel inherently possesses excellent strength and toughness. When used for excavator bucket teeth, these materials meet the strength and toughness requirements. If surface hardening techniques are further applied to them, the bucket teeth can achieve not only high wear resistance but also retain good plasticity and toughness.

Bucket teeth are crucial components of an excavator and are also the most vulnerable to wear. They consist of a tooth base and a replaceable tip, connected by a pin. Since only the tip wears out, replacing it is sufficient, making the quality of the bucket teeth critical for cost-effectiveness.

The forging tooth forming hydraulic press is the core machine in the forging tooth production process. By applying external force to the metal raw materials using this press, it causes plastic deformation of the metal, changing the shape and size of the billet while improving its internal structure and mechanical properties, resulting in the final formed forging tooth. Forging eliminates defects such as porosity generated during the metal smelting process, optimizes the microstructure, and since it preserves the complete metal flow line, the mechanical properties of forgings are generally superior to castings made from the same material. Therefore, although the forging tooth production process is costlier, it ensures the highest quality for the forged teeth. The forging tooth is a crucial component on excavators, similar to human teeth, and is an easily worn part, requiring continuous production and processing to meet demand.
