| 摘 要： | 在钩体铸钢件生产过程中,发现钩身表面有使用刚性"U"形钢质芯撑形成的凹陷缺陷,不良品数量多,返工成本高.现探索使用一种常见性半硬型多孔可发性聚苯乙烯工程材料,热切成合适尺寸的实体块状结构,部分代替刚性"U"形钢质芯撑使用,钩体铸钢件在试制及批量化生产后,确认表面凹陷缺陷改善显著,取得了良好效果,现已推广应用于其他铸件生...

| Abstract: | During the production process of the coupler steel castings,it is found that the coupler surface has a concave defect formed by the rigid“U”-shaped steel chaplet,with a large number of defective products and high rework cost.A common semi-rigid porous expandable polystyrene engineering material was explored to be thermally cut into solid block structure with appropriate size and partially used instead of the rigid“U”steel chaplet.After trial production and mass production,it is confirmed that the surface depression defects of the coupler steel castings have been significantly improved and achieved very good results.It has been widely used in the productions of other castings. |
