| 中文摘要: |
| 介绍全钢子午线轮胎胎面挤出强制式口型板的设计技术。根据胎面胶经过挤出流道、预口型板和口型板时所受的剪切作用，分析导致挤出胎面破边、凸台、气孔和脱层缺陷的口型设计问题，采用强制式挤出方式，通过采取统一预口型板、固定口型板开型系数和恒比例开型等措施，胎面一次挤出不良率降低，挤出胎面形状和尺寸满足设计要求，挤出过程稳定，生产效率提高。 |
| 英文摘要: |
| The design technology of the constrained die plate for all steel radial tire tread extrusion was introduced. According to the shear effect on the tread compound through the extrusion channel，pre-forming die plate and die plate，the die designing factors which might cause tire tread extrusion defects such as edge damage，bulge，bubbles and delamination，were analyzed. Based on the analysis results，constrained extrusion die plate was designed with measures such as using the same opening coefficient for both pre-forming die plate and exit die plate and constant proportion opening，so that the tread defect rate was reduced. With the new die plate design technology，the profile and dimension of the extruded tread met the design requirements， the extrusion process was stable，and production efficiency was improved. |
