摘　　要：对造成轮胎胎圈打褶和胎里窝气缺陷的原因进行分析并提出相应解决措施。轮胎胎圈打褶问题主要通过调整机械手伸张直径公差范围、调整内套高度、增加"呼吸"动作、控制装胎高度和换用光面胶囊等方式进行解决;胎里窝气问题主要通过调整定型时间和增加定型排放的方式进行解决。采取改进措施后胎圈打褶和胎里窝气缺陷轮胎数量明显减少,节约了生产成本。The causes of tire bead folding and entrapped air defects were analyzed and the corresponding corrective actions were proposed.Tire bead folding problem was mainly solved by adjusting the tolerance range of the manipulator extension diameter,adjusting the height of the inner sleeve,adding the“breathing”action,controlling the height of the tire and changing to a smooth bladder.The air trapping problem was mainly solved by adjusting the tire shaping time and adding additional mold-venting operation during the tire shaping process.After the corrective actions were taken,the number of tires with bead folding and entrapped air defects was significantly reduced,and the production cost was reduced.
