斗轮堆取料机关键部件焊接变形研究及控制
|
摘要
斗轮堆取料机中,行走机构鞍座、焊接H型钢、法兰等关键部件不仅决定着部件之间的装配精度,更决定着整机的安装质量。焊接变形是导致加工成本高、热矫正工序多的主要原因。主要研究控制关键部件焊接变形的有效措施。结果表明,采取一定的工艺措施可以有效减小焊接变形。
In bucket wheel stacker-reclaimer, the key components such as saddle and welding H-section steel not only determine the assembly accuracy between components, but also determine the installation quality of the whole machine. Welding deformation is the main cause of high processing cost and many thermal correction processes. This paper mainly studies the effective measures to control the welding deformation of key components. The results show that the welding deformation can be effectively reduced by adopting certain technological measures.
