[0011] Beneficial effects

[0012] This utility model provides a die for forging bucket teeth rolls. Compared with the prior art, it has the following advantages:

[0013] 1. This bucket tooth roll forging die, by setting four sets of cavities with decreasing shapes and sizes, uses a robotic arm on the main body of the roll forging machine to hold the round steel and roll it multiple times in cavities of different sizes. This allows the round steel to be quickly forged into bucket teeth in a short time, greatly improving production efficiency. By adjusting the combination of different cavities and multiple roll changes, the size and shape of the bucket teeth can be precisely controlled to meet design requirements. Compared with traditional processing methods, forging bucket teeth by multiple roll changes can maximize the use of round steel raw materials and reduce material consumption and waste.

[0014] 2. This bucket tooth roll forging die, by setting a heat-conducting plate, allows the heat generated during the rolling process of the first and second dies to be quickly conducted to the first and second rotating rollers. By increasing the heat-receiving area, the heat dissipation effect of the first and second dies is enhanced. By setting air passage grooves and second air outlet grooves, when the first and second dies rotate, the external airflow can be quickly drawn into the air passage grooves through the air inlet, and then discharged quickly through the first and second air outlet grooves after heat exchange inside the air passage grooves. This improves the heat dissipation efficiency of the first and second dies and enhances the production quality of the forgings. Attached Figure Description
