铲斗主刀板是挖掘机铲斗工作的主要受力部件,针对公司进货检验发现及市场反馈某型号液压挖掘机铲斗主刀板开裂问题,从铲斗主刀板材料性能、有限元分析和焊接工艺等方面进行主刀板开裂原因分析,并提出实用有效的改善措施。经现场跟踪50台该型号液压挖掘机改善后的铲斗,铲斗主刀板没有出现开裂问题。
The main blade of the bucket is the main force component of the excavator bucket. According to the inspection of the incoming goods and the feedback of the market, the main blade of the hydraulic excavator of a certain type is cracked. The performance of the main blade of the bucket is analyzed from the material performance of the main blade, finite element analysis and welding technology And other aspects of the main knife cracking analysis, and put forward practical and effective improvement measures. After the scene tracking 50 models of hydraulic excavator improved bucket, bucket main blade does not appear cracking problem.
