分析全钢载重子午线轮胎肩部帘线弯曲质量缺陷的产生原因,并提出相应的解决措施。成型参数、挤出半成品尺寸、胎坯外周长和定型压力不当以及生产过程中的压延、挤出、成型、硫化工序出现偏差均会造成肩部帘线弯曲质量缺陷。控制钢丝帘线假定伸张值为1.2%~1.8%,准确制定半成品尺寸和胎坯外周长,一次定型压力设置为0.02~0.04MPa,严格控制压延张力、成型及硫化工艺等措施均可有效避免肩部帘线弯曲缺陷的产生。 相似文献

Influence to the steel cord conveyor belt strength has many factors. Conveyor belt splice as the weakest link, should be given more attention. In the previous analysis of single steel cord, by comparing the numerical results of splice deformation and maximum pullout force under tension, both simulation and experiment have a good agreement. Based on this, in this paper, we studied the influence of different factors on the strength of splices under multiple steel cords. In addition to the contact surface between the steel cords and the rubber, we should also pay attention to the rubber problem between adjacent steel cords compared to the single steel cord. And we forced on the simulation analysis of the influence strength of splice by two factors of the position and arrangement of the multiple steel cords. The numerical results show that in the total proportion, the pullout force in the middle position of steel cords was about 52%, however, about 47% in the edge position. For the arrangement of the steel cords, with the number of interval steel cords increases, the pullout force of the steel cord increases as well. However, when the interval steel cords with the same number increases, the increase in pullout force does not agree. The above findings are undoubtedly important for us to understand in depth the factors affecting splice strength. And it is guaranteed that we can obtain the maximum splice tensile strength in the most economical way. 相似文献
