Rail Clip
Rail clip, or elastic rail clip, is used to secure the rail to the underlying tie plate. By bending and deforming, the rail clamps can exert pressure on the rails to prevent longitudinal movement of the rail due to temperature changes and vibrations. Usually, the track clip is made of spring steel processed by hot forging method. With the most uniform microstructure, forged rail clips are considered better than other metal forming processes.

Rail clips production process
Raw material gathering—Shearing—heating to forging temperature—Forming—Hardening—Tempering—Surface Treatment—Inspection—Packing
The Spring steel bars should first be cut as required. By convention, the sheared bar is heated to 950 ° C to 1000 ° C, and then the heated rod is transferred to a power press for forging. Before hammering, keep three sets of molds and fixtures according to the drawings. The forged rail clips are conveyed to the quench tank. After checking the dimensional accuracy and the quenching hardness, the rail clips are sent to the next tempering procedure to achieve proper toughness in the spring. The final product will be packaged after rigorous inspection.
