摘　　要：液压矫直机及其矫直工艺很大程度上决定着产成品的质量、成材率与附加值,而三点反弯式压力矫直法是最早采用的反向压弯矫直工艺。3500 T大直径管棒材立式液压矫直机,采用压机固定的精密型半自动化技术方案,通过基于刚度指标的整体式机架、高/微速精确定位的纵向移动平台、人性化的电液联动控制等系统设计,很好的解决了工件顶升、旋转翻料、扶持降落、纵向定位移动、定量化压力矫直等工艺难题,对大弯曲度变形(包括鹅头弯)的大直径厚壁无缝管等取得了良好的矫直效果。Hydraulic Straightener and straightening technology depend a great extent on the quality, rate and added- value of finished material, three-point anti-bending is the earliest method of gag press straightening technology. The object of 3500 t vertical hydraulic straightener is to strengthen rods and bars with large diameter, the technical solu- tion of fixed press uses semi automation with precision type, the adopted technical scheme includes integral body frame based on stiffness, high/micro speed longitudinal shift platform with precise positioning, and humanized elec- tro-hydraulic actuating controller, etc. This scheme could solve the problem of workpiece jacking, rotary tipping, clamp-on lowering, longitudinal positing and quantitative gag straightening, so straightening effect has been obtained.
