| 中文摘要: |
| 对巨型工程机械子午线轮胎钢丝帘线挤出机传统的旋转、拆卸式机头进行重新设计与优化，改为以导轨形式液压前后水平移动及液压插销式锁紧的机头。采用新结构机头后：钢丝帘线挤出上下覆胶均匀；口型板和穿线板采用卡槽式设计，更换钢丝帘线规格时，操作时间缩短，设备产能提升；采用液压式插销和滚珠丝杠，装卸操作简化，节约时间，降低劳动强度；优化机头内流道形式，解决了重启动时钢丝帘线因胶料不足无法覆胶的问题。机头优化设计后，产品质量和生产效益得以提升，具有良好的经济效益和安全性。 |
| 英文摘要: |
| The traditional rotary and detachable head of steel cord extruder for giant OTR radial tire was redesigned and optimized，and changed to the head of hydraulic front and back horizontal movement and hydraulic bolt locking in the form of guide rail.After the new structure head was adopted，the extruded steel cord was coated with rubber evenly.The slot type design was adopted for the die and threading plate，when changing the specification of steel cord，the operation time was shortened and the equipment capacity was improved.Hydraulic bolt and ball screw were adopted to simplify loading and unloading operation，save operation time and reduce labor intensity.The inner flow channel form of the machine head was optimized to solve the problem that the steel cord could not be coated due to insufficient rubber during restart.After the optimized design of head，the product quality and production efficiency could be improved with good economic benefits and safety. |
