HXD1C型电力机车车体侧构组焊工艺

分析了HXD1C型电力机车车体侧构的焊接结构,根据其结构特点将侧构骨架分块成小骨架进行组焊,设计并制作了小骨架组焊工装.通过采用合理的组装、焊接顺序和焊接工艺规范,可以将侧构小骨架平面度控制在2 mm/2m之内,在侧构总组焊之后,将侧构整体平面度控制在3mm/2m之内,在车体组焊调平之后,将侧构平面度控制在2 mm/2...

Assembling and welding technology for sidewalls of carbody of type HXD1C electric locomotive

This article analyzes the welding structure of the sidewalls of the carbody of type HXD1C electric locomotive.The sidewall framework is divided into small parts to be welded,and a set of fixture is designed.By adapting the reasonable assembling,welding sequences and welding technique,the small sidewall framework could be controlled within 2 mm/2 m,after the sidewall summarizedwelding,the sidewall flatness could be controlled within 3 mm/2 m.And after the in vehicle body welding leveling,the sidewall flatness could be controlled in 2 mm/2 m,which satisfies the design requirements and customer needs.
