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 application discloses an integrated production process of forging bucket teeth with casting, forging and quenching, which includes a casting step, a water toughening treatment step, a feeding step, a forging step, a trimming step and a quenching step. After the trimmed casting is rinsed, it is tempered at a low temperature and quenched to obtain bucket teeth. This forged bucket tooth casting, forging and quenching integrated production process reduces the number of pores in the bucket teeth by combining casting and forging, and improves the mechanical properties of the bucket teeth such as toughness, impact resistance and wear resistance. Conducive to saving production costs.

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...
