With low carbon and low alloy steel zg14crmnsini, the wear resistance and hardness of bucket teeth are improved by advanced liquid die forging technology. A set of production process and equipment scheme of liquid die forging are designed, which can significantly improve the service life of bucket teeth. The...
In recent years, researchers at home and abroad have made great achievements in the research of bucket tooth alloy materials. It is found that the Ni Cr Mo low-carbon low-alloy martensitic steel developed by Amsco company has good strength and toughness, especially suitable for thin, long and sharp bucket...
Based on the use of bucket teeth in production, according to the components of bucket teeth, they can be divided into the following types: 1. High manganese steel bucket teeth High manganese steel is used as the material of bucket teeth earlier. At present, the vast majority of excavators’...
1. Improvement of structure From the actual failure of the bucket teeth, it is found that the tooth tip is the most easily worn place in theory, but a part of the bucket teeth failure is broken from the middle, which shows that the structure of the bucket teeth...
The bucket teeth need to bear the impact and bending moment from the material when contacting the material. During the working process, the surface of the bucket tooth tip often appears various furrows, spalling and deformation after the big impact on the bucket tooth tip, resulting in surface wear...
Excavator is a common important construction machinery, which is widely used in many industries of national economic construction, and plays a very important role in production and life. The bucket tooth of excavator is an important part on the machine and also a vulnerable part. At present, there are...
