How are rail elastic clips produced

Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Usually rail clips are made of forged spring steel which is produced by hot forging process. Because of the uniform microstructure of forged clips, it is considered to be better than other metal forming process.

Production Processes of Elastic Rail Clips:

• Rail clip processing procedures includes:
• Raw material purchasing
• Shearing
• Heating to forging temperature
• Forming
• Hardening
• Tempering
• Surface treatment
• Inspection-Packing

Raw material refers to a long spring steel rod. The first step is to shear the raw materials into the required length. Then put the sheared spring steel into the heating furnace. The temperature in the furnace is 950-1000℃. After heating, the clips are formed through three stages of bending by hot molding equipment. After forming, the elastic rail clips are conveyed to a quenching oil tank. After quenching, the elastic rail clips are tempered at 400-500°C. The elastic rail clips are finally oiled and packed. The elastic rail clips must have a hardness between 40 and 48 HRC.
