全钢工程机械子午线轮胎胎圈外观缺陷原因分析及解决措施

Cause Analysis and Solution of Bead Appearance Defects of All-steel Off-The-Road Radial Tire

分析全钢工程机械子午线轮胎硫化过程中胎圈外观缺陷产生的原因,并提出相应解决措施。通过分析蒸锅内蒸汽循环对硫化过程的影响、胶囊根部排气线堵塞、胶囊根部堆积问题及机械手爪片宽度设计问题后,对硫化工艺缺陷进行针对性处理,硫化过程造成的胎圈外观缺陷率由10%减小至2%。

The causes and corresponding solutions of bead appearance defects of all-steel off-the-road radial tire during curing process were analyzed.The influence of steam circulation in the steamer on curing process,the blockage of exhaust line at the root of bladder,the accumulation at the root of bladder,and the design of the width of mechanical gripper were analyzed.The defects in the curing process were solved and the appearance defect rate of tire bead caused by curing process was reduced from 10%to 2%.
