Under-plate backing plate for rail fastener and manufacturing method thereof
According to the under-plate backing plate for the rail fastener and the manufacturing method of the under-plate backing plate, the process of foaming the backing plate is used, the vibration reduction performance of the under-plate backing plate is improved, and materials consumed during backing plate production are saved. And secondly, the through round holes are uniformly formed in the surface of the base plate, so that the rigidity of the base plate can be further reduced, the base plate meets the low-rigidity requirement of the damping fastener, and meanwhile, compared with a low-rigidity base plate on the market, a die for producing and processing the base plate is simplified. In addition, the shape and the opening form of the under-plate base plate are easy to design and adjust, and the under-plate base plate can be matched with iron base plates of different types of fasteners.
本发明提供了一种轨道扣件用板下垫板及其制作方法，使用了发泡垫板的工艺，既提升了板下垫板的减振性能又节省了垫板生产时消耗的材料。其次，在垫板表面均匀设置贯穿圆孔，能够进一步地降低垫板的刚度，使得垫板满足减振扣件的低刚度要求，同时相较于市面上的低刚度垫板，也简化了垫板生产加工的模具。此外，板下垫板的形状和开孔形式均易做设计调整，可适配不同类型扣件的铁垫板。
