轮胎硫化异步胀缩内模具的设计
|
摘要
提出一种基于轮胎直压硫化工艺技术的轮胎硫化异步胀缩内模具设计方案。首先针对斜楔式内模具的局限性,设计了一种适用于尺寸较小、扁平比较大的异步胀缩伸缩方式轮胎硫化内模具,以205/40R17规格轮胎进行新内模设计,并结合不干涉条件和几何特性分析建立约束方程,确定了异步胀缩内模具的尺寸参数;在此基础上,为确保异步胀缩内模具的可靠性,对硫化压力状态下内模具的关键部件进行了强度校核。
A new design of a tire curing inner mold using an asynchronous telescopic method, which is based on direct-pressure tire vulcanization technology, has been proposed. The design of the curing inner mold is intended to compensate for the deficiency of conventional wedge-shaped tire curing molds. The new type of tire curing mold is suitable for tire specifications with small size and high aspect ratio. The design is based on tires with specification 205/40 R17. The constraint equations of the mold are established by employing noninterference conditions and analysis of geometric characteristics. The dimension parameters of the asynchronous telescopic tire curing inner mold are then determined. To ensure the reliability of the mold, strength analysis of the key components of the mold under direct-pressure vulcanization has been carried out.
