摘　　要：针对链板铰卷传统卷圆工艺的缺陷,结合市场对平顶链高速运行平稳性的要求,从提高链板铰卷圆度和链板平面度入手,改进链板铰卷成形工艺,重新设计传统卷圆预弯尺寸,增加二次预弯。采用有芯棒卷圆的卷圆校正工序,并在压紧状态下调整芯棒尺寸,以提高链板平面度和铰卷圆度,使输送用平顶链在高速运行的条件下实现了平稳输送。In view of the defects of traditional crimping process for chain plate, the paper improves the process of chain plate hinge ring forming, redesigns the round size of the traditional roll bending and increases secondary bending combined with requirements of the stability for high-speed running from the aspect of improving the roundness of the hinge roll and flatness of the chain plate. Besides, the paper adopts the correction process for the roll round and adjusts the size of the roll round under pressing status to improve the flatness of the chain plate and the roundness of the hinge to ensure the stable running under high-speed conditions.
