The manufacturing process of elastic bar
2021-08-02
Because the contact between the wheel and the rail running on the track is a rigid contact,it will inevitably produce vibration,and the special elastic structure of the elastic bar can absorb the impact energy generated when the vehicle passes,to achieve the role of shock absorption,so that the vehicle running more stable and safer.
The elastic bar is used with the Railway Sleeper to fix the rail on both sides.The spring bar is usually made of forged spring steel and is made by a hot forging process.Forged elastic bars are considered better than other metal-forming processes due to their more uniform microstructure. Elastic bar manufacturing process is as follows:shear-heating to forging temperature-molding-hardening-tempering-inspection-packaging.
