新型轮胎内模直压硫化机构设计

Design of a novel mechanism for tire inner mould direct-pressure vulcanization

提出一种新型轮胎内模直压硫化制造技术并设计了轮胎内模直压硫化装备,将中心机构上的胶囊替代为刚性内模直压机构,利用电磁感应加热实现轮胎内腔加热。以关键部件内模直压机构结构特点及工作原理为基础,建立了内模直压机构的几何与运动约束方程,实现了内模直压机构的尺度设计。另外,还利用Abaqus结构分析模块对硫化状态下的内模直压机构进行强度分析及结构改进设计,得到了内模直压机构的最佳结构。

A new type of tire inner mould direct-pressure vulcanization technology has been proposed,and the necessary tire inner mould direct-pressure vulcanization equipment was designed.By utilizing the rigid inner mould direct-pressure mechanism to replace the curing bladder of the central mechanism,the heating of the tire cavity depends on electromagnetic induction.The key component is the inner mould direct-pressure mechanism and,based on its structural characteristics and working principles,the equations of geometry and motion were established.Dimensional design of the inner mould direct-pressure mechanism was carried out.In addition,in order to improve the structure of the inner mould direct-pressure mechanism and give sufficient strength during vulcanization,the structure analysis module of Abaqus was used to analyze the strengths of the mechanism.Finally,an optimum scheme was obtained.
