Product Description

                Factory Supply E Type Rail Clamps for Railroad Accessories in Large Quantity
 

Product Description

The rail elastic clips (also called rail clip, elastic rail clip )are used with railway sleeper to fasten rails on both sides. The rail clips are usually made of forged spring steel, which are manufactured by hot forging process. The forged rail clips are considered to be better than other metal forming process due to most uniform microstructure.
For meeting various needs of clients, We supplies E-clips, PR clip, SKL clips, Russia rail clip, Deenik clip, Nabla spring blade, KPO rail calmp, gantrex rail clips, fast clip, crane rail clip and other special clips for rails. We have proffesional production cline to design and manufacture standard rail clips or nonstandard clips. welcome to as

Production Processes of Elastic 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

To produce rail clips usually use spring steel bar as the raw materials, before heating, raw materials must be sheared according to the length required. Then they are heated to 950ºC to 1000ºC, next works transfer the heated bar to power press for forging, in accordance with drawing three sets of dies and fixtures are kept before hammering. The following procedure is to convey the forged rail clips to quenching tank. Then check the dimensional accuracy and quench hardness of the rail clips. The next procedure is tempering to achieve appropriate toughness in the spring. And the final step is to pack the rail clips after serious inspection.
