China wholesale Undercarriage Spare Parts For Bulldozer - Bucket Teeth Heavy Duty – Pingtai

The process flow of excavator bucket teeth: sand casting, forging casting, precision casting.
Excavator bucket tooth is an important consumable part on the excavator. It is similar to human teeth. It is a combination bucket tooth composed of tooth base and tooth tip, and the two are connected by the pin shaft. Because the bucket tooth wear failure part is the tooth tip, as long as the replacement of the tip can be.
Classification according to the use environment of excavator bucket teeth. Excavator bucket teeth can be divided into rock teeth (used for iron ore, stone ore, etc.), earthwork teeth (used for digging soil, sand, etc.), conical teeth (used for coal mine).
Excavator bucket teeth can be divided into horizontal pin bucket teeth (Hitachi excavator), horizontal pin bucket teeth (Komatsu excavator, Caterpillar excavator, Daewoo excavator, Kobelco excavator, etc.), rotary digging bucket teeth (V series bucket teeth).

Excavator bucket teeth under normal working conditions for 3 days (about 36 hours) will fail to qualify as unqualified products. There are obvious furrow scratches on the surface of bucket teeth and a small amount of plastic deformation at the tip. The force analysis of the bucket tooth working face and the excavated object contact, in a complete excavation process in different stages of different stress, the tip part of the first contact with the material surface, because the speed is fast, the tip of the bucket tooth by a strong impact. If the bucket tooth yield is low, it will produce plastic deformation at the tip. The unqualified bucket teeth were ground, polished and corroded, and found to be light gray around and dark in the middle, indicating that the bucket teeth were cast inserts. The main alloy components (mass fraction %) are 0.38C, 0.91Cr,0.83Mn and 0.92Si.The mechanical properties of metal materials depend on the composition and heat treatment process of the material factory.

Bucket tooth performance analysis by MLD-10 wear test machine wear test. The wear resistance of the matrix and inserts is better than that of the quenched 45 steel under the condition of small impact wear. At the same time, the wear resistance of the matrix and the inserts is different. The matrix is wear-resistant than the inserts. The composition on both sides of the matrix and the inserts is close to that in the bucket teeth. The insert in the bucket tooth is mainly to play the role of cold iron. During the casting process, the matrix grain was refined to improve its strength and wear resistance. Due to the influence of casting heat, the inserts produce similar structures in the welding heat affected zone, which does not play a role in enhancing the wear resistance. If appropriate heat treatment is carried out after casting to improve the structure of the inserts, the flax resistance and service life of the bucket teeth will be significantly improved.
