辊式矫直是改善板型、消除残余应力、获得合格金属板带材的重要工艺环节,其工艺水平直接决定产品品质。在矫直设备组成中,矫直驱动系统作为矫直过程中变形能的来源,对矫直设备的设计和矫直工艺的制定有较大影响。通过试验研究,对矫直驱动系统的实际受载和理论计算值进行对照分析。研究表明,矫直咬入阶段的冲击载荷是矫直辊接轴损坏的主要原因,单根矫直辊扭矩试验值是理论计算值的近4倍;同时在矫直过程中,由于集中传动的影响,试验驱动扭矩分布与理论计算存在较大的不同。其中,3、4号矫直辊承担了弯曲变形大部分的驱动功。 Roller straightening is to improve the plate, eliminate residual stress, access to qualified sheet metal strip an important part of the process, the level of technology directly determines product quality. In the composition of straightening equipment, straightening drive system as a source of deformation energy in straightening process, straightening equipment design and straightening process has a greater impact. Through experimental research, the actual load of the straightening drive system and the theoretical calculation value are analyzed. The research shows that the impact load of the straightening and nipping phase is the main reason for the damage of the connecting shaft of the straightening roller. The torque test value of the single straightening roller is nearly 4 times the theoretical value. At the same time, in the straightening process, Influence, test drive torque distribution and theoretical calculation there is a big difference. Among them, No. 3 and No. 4 straightening rollers bear most of the driving force of bending deformation.
