Manufacturing method of railway magnesium alloy base plate
The invention discloses a manufacturing method of a railway magnesium alloy base plate, and relates to the technical field of base plate manufacturing, the method comprises the following steps: S1, respectively crushing magnesium, aluminum and zinc cast ingots into particles; s2, magnesium particles, aluminum particles and zinc particles are mixed in proportion and put into a hopper; s3, melting and plasticizing the mixed particles; s4, injecting the molten mixture into a mold cavity at a high speed; s5, cooling and demolding; and S6, post-processing to obtain the magnesium alloy base plate. Magnesium, aluminum and zinc cast ingots are crushed, mixed and then fed into injection molding equipment through a quantitative feeding device, magnesium, aluminum and zinc are manufactured into the magnesium alloy railway base plate, aluminum can improve the strength and corrosion resistance of alloy, zinc plays an auxiliary reinforcing role, a primary blank is manufactured through cooling and demolding, and after the shape is confirmed after coarse grinding, fine grinding and polishing, the magnesium alloy railway base plate is obtained. Chemical nickel plating is adopted as the bottom layer, then direct current nickel plating is adopted, a microcrystal nickel plating layer can be obtained, the anti-corrosion capacity of the magnesium alloy base plate is improved, and therefore the vibration reduction performance is improved, and the service cycle is prolonged.
本发明公开了一种铁路镁合金垫板的制造方法，涉及垫板制造技术领域，该方法包括以下步骤：S1、将镁、铝、锌的铸锭分别粉碎成颗粒；S2、按照比例混合镁、铝和锌颗粒并投入到料斗中；S3、混合颗粒熔融塑化；S4、将熔融状的混料高速注射到模具型腔中；S5、冷却脱模；S6、后处理得到镁合金垫板。本发明通过将镁、铝和锌铸锭粉碎混合后经定量供料装置送入到注射成型设备中，将镁、铝和锌制造成镁合金铁路垫板，铝可以提高合金的强度和耐腐蚀性，锌起到辅助增强作用，冷却脱模制成初胚，经过粗磨、细磨和抛光后确认好形状后，采用化学镀镍作为底层，再用直流电镀镍能得到微晶镍镀层，提高镁合金垫板的防锈蚀能力，以此提高减振性能和延长使用周期。
