Process procedures of rail clips
The complete process procedures of rail clips include:
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.
