Carter excavator bucket tooth is widely used in excavator and other machinery.Bucket tooth casting method is not many.Sand casting and precision casting.Forging bucket teeth high cost, small output.

The bucket tooth of small excavator is sometimes damaged to different degrees during working, which leads to the failure of bucket tooth.Force analysis generally indicates that the bucket tooth surface is in contact with the excavation.In the whole process of excavation, the stress of different working stages is different.When the tooth tip contacts the material surface for the first time, because of its fast speed, the bucket tip is strongly impacted.When the yield strength of bucket teeth is low, plastic deformation will occur on the top.With the increase of excavation depth, the force on bucket teeth will change.When the bucket tooth cuts the material, the bucket tooth moves relative to the material, resulting in greater positive extrusion pressure on the surface of the material, thus generating greater friction between the bucket tooth working face and the material.
