The bucket tooth of excavator is the main vulnerable part of excavator, which is similar to human teeth. It is composed of tooth seat and tooth tip, which are connected by pin shaft. Because the bucket tooth is worn, the failure part is the tooth tip, so long as the tip is replaced.
Bucket teeth are generally different from cast bucket teeth and forged bucket teeth. Generally, forged bucket teeth are more wear-resistant and harder. Their service life is about twice that of cast bucket teeth, and the price is about 1.5 times that of cast bucket teeth.
Casting bucket teeth: the method of casting liquid metal into a casting cavity suitable for the shape of the part and obtaining the part or blank after it is cooled and solidified is called casting. The mechanical properties, wear resistance and service life of castings are lower than those of forgings.
Forging bucket teeth: the forging machine is used to apply pressure on the special metal blank, which is extruded at high temperature to refine the crystal in the forging to produce plastic deformation, so as to obtain certain mechanical properties. The metal can improve its organizational structure after forging, which can ensure that the forged bucket teeth have good mechanical properties, more wear resistance and longer service life.
1. During the use of the bucket teeth of the excavator, the bucket teeth outside the bucket Z are 30% faster than the wear parts inside the bucket Z. after a period of time, the positions of the bucket teeth inside and outside can be changed.
2. During operation, the excavator driver shall try to dig under the bucket teeth perpendicular to the working face to avoid breaking the bucket teeth due to excessive inclination.
3. Do not swing the excavation arm left and right under the condition of large resistance, so it is easy to break the bucket teeth and tooth seat due to excessive left and right force, and the left and right force design is not considered.
4. It is recommended to replace the tooth seat when the tooth seat is worn out by 10%. There is a large gap between the tooth seat with excessive wear and the bucket tooth, which changes the fit between the bucket tooth and the tooth seat and the force point, and the bucket tooth is broken due to the change of the force point.
