Problems solved by technology

The existing bucket tooth processing methods include casting and forging. Both methods have their own advantages and disadvantages. For example, casting is not limited by the size and shape of the casting, has good adaptability, and has a small amount of cutting. However, the casting is prone to pores during the casting process. The formation of trachoma has certain defects in its mechanical properties and wear resistance, while the mechanical properties and wear resistance of forgings are better, but forgings are prone to surface cracks or scars and layered fractures, and the amount of cutting after forming is large

Abstract

The invention discloses a forging bucket tooth casting, forging and quenching integrated production process. The forging bucket tooth casting, forging and quenching integrated production process comprises a casting step, a water toughening step, a material adding step, a forging step, a trimming step and a quenching step. After a trimmed casting is washed clean, low-temperature tempering and quenching are conducted, and therefore a bucket tooth is obtained. According to the forging bucket tooth casting, forging and quenching integrated production process, casting and forging are combined, thenumber of air holes of the bucket tooth is reduced, the toughness, impact resistance, abrasion resistance and other mechanical properties of the bucket tooth are improved, and meanwhile the productioncost can be saved.

Description

technical field [0001] The application relates to the technical field of bucket tooth manufacturing, in particular to an integrated production process of forged bucket teeth with casting, forging and quenching. Background technique [0002] Bucket teeth are cutting parts of construction machinery such as excavators. They are installed on the front edge of the excavator bucket. When working, the bucket teeth are used to achieve cutting. Bucket teeth, as cutting parts, directly affect the effect of excavation and mechanical efficiency. Therefore, there are high requirements for the strength, toughness, hardness and wear resistance of bucket teeth. The existing bucket tooth processing methods include casting and forging. Both methods have their own advantages and disadvantages. For example, casting is not limited by the size and shape of the casting, has good adaptability, and has a small amount of cutting. However, the casting is prone to pores during the casting process. The...
