    济南装载机铲斗主刃板变形的原因
    2014-12-27 18:05:05

    济南装载机铲斗主刃板往往出现上拱、下塌、扭曲等变形,那么引起济南装载机铲斗主刃板变形的原因有哪些呢?下面山东永保机械的有关技术人员就给大家详细分析一下。

    1、济南装载机http://www.sdyongbaojixie.com/铲斗主刃板为板材气割下料后外协加工件,由于板材的装卸、运输、存储等原因造成主刃板出现上拱、下塌和挠曲变形。铲斗底部焊缝主要集中在背面,焊缝密集并且焊缝形式不合理使焊接工作量和热输入量都相当大,铲斗结构和背面焊缝布置。
    Jinan loader bucket main blade plate after plate of gas cut material for contract manufacturing parts, due to plate handling, transportation, storage, and other causes of the main blade plate appears on the arch collapsed and

    deflection. Buckets are mainly concentrated in the back of the bottom of the weld, the weld seam in the form of intensive and unreasonable workload and the welding heat input are quite large, bucket structure and arrangement of the back seam.

    2、济南装载机由于主刃板的挠曲变形,使主刃板与斗底板、斗壁板对接间隙加大并且不均匀,对接间隙的加大增加了焊接工作量和焊接热输入量,间隙的不均匀使焊接热输入量不均匀,焊后冷却收缩变形量就会不均匀,这样各焊缝冷却后,就会使斗底板、斗壁板、主任板产生相应的焊接变形。
    Jinan loaders due to the deflection of the main blade plate, the main blade plate and the bottom bucket, bucket siding butt gap increased and uneven, butt weld gap increased workload and increased heat input welding, the gap is not

    uniform heat input welding uneven cooling capacity will be uneven shrinkage deformation after welding, so that after each weld cooling, it will make the floor bucket, bucket siding, director of the board to produce the corresponding

    welding deformation.
      
    3、济南装载机在斗壁板卷板时,因两端受力不均或压型线与斗壁板两边不平行等原因而出现扭曲,这样与主刃板对接后带动主刃板扭曲,这样各步工序产生的误差和焊接变形都集中到一起,致使铲斗焊接完毕后,主刃板产生变形。
    Jinan loader bucket wall when Coil, because both ends of the uneven force or pressure-type lines on both sides are not parallel with the bucket wall and other reasons, distorted, so that after docking with the main blade plate driven by

    the main blade plate twisted, so each error and welding deformation step process all together to produce, resulting in a bucket after welding is completed, the main blade plate deformation.
     
    4、 济南装载机http://www.sdyongbaojixie.com/铲斗主刃板外协加工回厂后,对平整度不符合要求的进行校平,对挠曲变形的,把与斗壁板对接的边缘采用半自动火焰切割机进行气割,这样经过处理后,保证了主刃板的平直。

    cutting, so that after after the treatment, to ensure that the main board of the straight edge.
