摘要：

为降低轨道交通用车轮模具的制造成本，对原整体模具结构进行分类拆分。根据车轮锻坯特征尺寸将原消耗性模具分别分为易磨损的消耗性部件和少、无磨损的通用部件。对于消耗性部件尽可能降低其体积和重量，对于少、无磨损部件则设计为系列化通用模具，以供不同规格车轮长期使用。与原整体模具结构相比，分体模具结构具有节约原材料、实现独立修复性等显著的优点。通过计算与对比，得出使用分体模具后其易磨损模具总重量比使用整体模具时降低了47.7%，单件车轮的模具总投料重量降低了28.4%，从而有效地降低了模具制造成本。生产实践表明，改进后的分体模具结构可适用于所有常规车轮的锻造使用，并在生产中取得了良好的应用效果。

In order to reduce the manufacturing cost of wheel molds for rail transit, the original overall mold structure was classified and split, and according to the characteristic sizes of wheel forging billet, the original consumable molds were divided into consumable parts that were easy to wear and the general parts with little or no wear. Then, the volume and weight of the consumable parts should be reduced as much as possible, and the little and no wear parts were designed as a series of general molds for the long-term use of wheels with different specifications. Compared with the original overall mold structure, the split mold structure has the advantages of saving raw materials and realizing independent repair. Furthermore, through calculation and comparison, it is concluded that the total weight of the easy-wear mold after using split mold is reduced by 47.7% compared with that of the overall mold, and the total feeding weight of the mold for a single wheel is reduced by 28.4%, which effectively reduces the manufacturing cost of the mold. The production practice shows that the improved split mold structure is available for the forging of all conventional wheels and achieves good application results in production.
