中文摘要：针对钢制实心三角皮带轮辊轧成形新工艺，分析了轧制件的质量缺陷及其原因。结果表明：试制的辊轧机液压式压紧装置存在压紧力设计不足、未构成封闭力系、机械结构与液压系统的刚性小等问题，不能保证成形过程对工件的压紧。并提出了采用肘杆机构实现对工件锁紧的解决对策。
英文摘要：Considering new rolling process of solid steel V-belt pulley, the quality shortages of the workpieces and the cause were analyzed. The results show that some problems, such as the force supply of design is not enough, and a close force system is not formed, and the mechanical rigidity and hydraulic system rigidity are too weak, exist in the hydraulic hold-down unit of the trial-produce machine. Therefore, the axial press force is not enough in deformation process, then a countermeasure applying the elbow-pole mechanism to the hold-down unit is proposed.
