Rail Clip

Rail clip, or called elastic rail clip, is used to fasten steel rails to the underlying tie plate. Through bending and distortion, rail clip can put pressure on the rail, which prevents longitudinal movement of the rail, either from changes in temperature or through vibration. In general, rail clips are made of forged spring steel produced by hot forging process. Because of the most uniform microstructure, the forged rail clips are considered to be better than other metal forming process.

Process procedures of rail clips

1. Raw material purchasing
2. Shearing
3. Heating to forging temperature
4. Forming
5. Hardening
6. Tempering
7. Surface treatment
8. Inspection-Packing

The spring steel bar should first be sheared as per length required. By convention, the sheared rods are heated to the 950 ℃ to 1000 ℃, and then the heated bars are transferred to power press for forging. Three sets of dies and fixtures are kept as per drawing before hammering. The forged rail clips are conveyed to quenching tank. After checking dimensional accuracy and quench hardness, rail clips would be sent to the next procedure for tempering to achieve appropriate toughness in the spring. The final product will be packed after serious inspection.
