濟南裝載機鏟斗主刃板變形的原因

濟南裝載機鏟斗主刃板往往出現上拱、下塌、扭曲等變形，那么引起濟南裝載機鏟斗主刃板變形的原因有哪些呢？下面山東永保機械的有關技術人員就給大家詳細分析一下。

1、濟南裝載機http://m.ts0775.cn/鏟斗主刃板為板材氣割下料后外協加工件，由于板材的裝卸、運輸、存儲等原因造成主刃板出現上拱、下塌和撓曲變形。鏟斗底部焊縫主要集中在背面，焊縫密集并且焊縫形式不合理使焊接工作量和熱輸入量都相當大，鏟斗結構和背面焊縫布置。
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、濟南裝載機由于主刃板的撓曲變形，使主刃板與斗底板、斗壁板對接間隙加大并且不均勻，對接間隙的加大增加了焊接工作量和焊接熱輸入量，間隙的不均勻使焊接熱輸入量不均勻，焊后冷卻收縮變形量就會不均勻，這樣各焊縫冷卻后，就會使斗底板、斗壁板、主任板產生相應的焊接變形。
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、濟南裝載機在斗壁板卷板時，因兩端受力不均或壓型線與斗壁板兩邊不平行等原因而出現扭曲，這樣與主刃板對接后帶動主刃板扭曲，這樣各步工序產生的誤差和焊接變形都集中到一起，致使鏟斗焊接完畢后，主刃板產生變形。
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、 濟南裝載機http://m.ts0775.cn/鏟斗主刃板外協加工回廠后，對平整度不符合要求的進行校平，對撓曲變形的，把與斗壁板對接的邊緣采用半自動火焰切割機進行氣割，這樣經過處理后，保證了主刃板的平直。

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