铁路起重机槽板折弯质量问题工艺研究

Analysis of bending quality problem of railway crane trough plate

槽板是铁路起重机的核心受力零部件,其产品质量直接影响整机的性能和使用寿命。针对槽板折弯过程中的挠曲、断面不良、回弹变形、折弯角度不一致和折压线偏差等影响产品精度的惯性质量问题进行分析和研究,找出主要影响因素,制定预防改进措施,实施过程监控,达到槽板产品质量的改善和受控的目的。

As the key load-bearing component,trough plates quality directly affect the performance and service life of railway crane.Common problems affecting its precision in bending process,including deflection,improper profile,springback,bending angle inconsistency and folding pressure line deviation,were analyzed.By finding out main influence factors,taking prevention measures and implementing process monitoring,trough plates quality could be improved and controlled.
