摘　　要：分析农业子午线轮胎成型胎坯质量缺陷原因,并提出相应的解决措施。农业子午线轮胎成型设备由2段胶囊反包成型机和胎面缠绕生产线组成。2段成型胎坯的主要质量问题为胎圈部位打褶/起泡、帘布层打褶/起泡和胎圈钢丝偏歪;胎面缠绕胎坯的主要质量问题为缠绕胶料质量和缠绕胎面外观几何尺寸不满足要求、缠绕胎面凹凸不平、缠绕胶条和胎坯起泡及缠绕胎面偏歪等。通过调试设备程序、及时维护和修理设备及规范对中等成型操作,有效解决了成型胎坯质量缺陷问题,提高了成型胎坯质量。The causes for the green tire quality defects of agricultural radial tire were analyzed,and the corresponding solutions were put forward. The building equipment of agricultural radial tire consisted of a two-stage capsule turning-up building machine and a tread winding production line. The main quality problems of the two-stage formed green tire were the wrinkling and bubbling of the bead area,the wrinkling and bubbling of the cord layer and the deflection of the bead wire. The main quality problems of the tread part were unsatisfactory quality of the rubber material and unsatisfactory geometric dimensions of the winding tread,the unevenness of the winding tread,the bubbling of strip and green tire,and the deflection of the winding tread. By debugging the equipment program,keeping timely equipment maintenance,and standardizing the building operation such as centering,the quality defects of the green tire were effectively solved,and the quality of the green tire was improved.
