液压支架超薄顶梁焊接变形研究及对策

Research and Countermeasure of Hydraulic Support Top Beam Welding Deformation of Thin

阐述了液压支架超薄顶梁制造中存在的几点问题,介绍了通过采取增加主肋板上翘量及控制主肋板、横肋板外形尺寸、增加顶梁自身刚性和正确的焊接顺序的对策。生产实践表明,采用这些对策解决了顶梁在制造中存在的问题,并满足了顶梁的使用、安装性能和外观要求,取得了理想效果。

Expounds some problems existing in the manufacture of ultra thin beam of hydraulic support, introduced by increasing the main rib plate upturned amount and controlling the main rib plate, a transverse bar plate dimensions, increase its rigidity and the right top beam welding sequence of the countermeasures. The production practice indicated that, using these measures to solve the existing problems in the manufacture of top beam, beam and meet the use, installation performance and appearance requirements, and achieved ideal effect.
