巨型全钢工程机械子午线轮胎成型机成型鼓全自动后压辊的设计

摘要

介绍51英寸（1295.4 mm）以上规格巨型全钢工程机械子午线轮胎成型机成型鼓全自动后压辊[滚压胎坯上贴合的附件（垫胶、胎侧附胶等）]的设计。全自动后压辊采用三轴压辊进行三维滚压，实现270°无死角滚压；径向和轴向压辊使用伺服电机，旋转压辊使用变频电机和增量编码器；压辊摆臂与成型鼓的中心线垂直，缓冲区域使用空气弹簧。成型机成型鼓采用全自动后压辊后，轮胎生产的可靠性和稳定性提高，劳动强度降低。%The automatic back roller of the molding machine for giant all-steel OTR radial tire (51 inchesor above) was designed and it was used for the lamination of pad rubber and sidewall compound. The automatic back roller achieved three-dimensional rolling and covered a wide angle up to 270°. The radial and axial movements were driven by servo motors, and the rotation movement was driven by converter motor and incremental encoder. The pressing arm was perpendicular to the centerline of the forming drum, and air springs were applied in the buffer area. With the design of automatic back roller, the reliability and stability of the tire molding machine were improved and the labor intensity of tire production was reduced.
