Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant steel ball production equipment, in particular to a steel rod conveying mechanism for conveying round steel rods. Background Art

[0002] Ball mills are key equipment for material pulverization and are widely used in industries such as cement, nonferrous metal mining, and glass and ceramics. Ball mill steel balls (wear-resistant steel balls) are the medium used to pulverize materials and are the most consumable part in the mill. Ball forging machines are automated equipment that cuts round steel bars into steel ball blanks and then punches these blanks into steel balls, enabling the automated production of wear-resistant steel balls.

[0003] Round steel bars are typically 6 meters long, and their straightness is required to be within 5‰ according to national standards. However, during transportation, these bars can easily bend to varying degrees, especially during hoisting. When conveying bent round steel bars, the rollers holding the conveying bars in existing ball forging machines struggle to effectively clamp them. One or more rollers can become disengaged from the bar, affecting the linear feeding of the bars. Utility Model Content
