- All fast rail clips components are fully pre-assembled on the rail sleeper when the sleeper is delivered.
- When the fastener is pushed into the working position, the correct tensioning will be automatically realized.
- The cast embedded base will fix the rail to the correct gauge and set the correct deflection of the quick spring fastener.
- In the manufacturing process, the embedded base is cast into the sleeper.
- During the process of applying stress to the rail, all components are kept in a tethered state.
Functions of Fast Rail Clips
Fixing rails
The fast rail clips securely fastens the rails to the sleepers or track plates using a variety of parts to stop the railroad track from slipping or deflecting,
Withstanding train loads
To prevent undue strain on the sleepers, the fast rail clips must be able to sustain the longitudinal, lateral, and vertical forces produced by the train’s operation while also distributing these forces uniformly to the sleepers.
Providing elasticity and buffering
There will be collision and vibration between the train wheels and rails. By using elastic components (such as spring fasteners and track gaskets) to absorb these dynamic loads, the fast rail clips lessens damage to the sleepers and rails while enhancing ride comfort.
Anti-fatigue
The design of the fast rail clips requires long-term anti-fatigue performance. Also, the ability to maintain stable fixing forces in complex environments is needed.
Fast Rail Clips Manufacturing Process
Raw material
In general, fast rail clips is made of steel bar. Steel refers to the steel specifically for manufacturing spring and elastic components due to the elasticity in the quenched and tempered state. Steel has excellent comprehensive performance like mechanical properties, performance by the bullet-proof, fatigue, hardenability, physical and chemical properties.
Shearing
The processing method of fast rail clips mainly adopts hot forging process. The raw material which is steel has to be sheared as per length required.
Heating
After shearing, steel should be heated to forging temperature (950-1000 degrees Celsius). One thing to notice about this link is that excessive heating should be avoided to check decarburization.
Forming
When the steel bar is heated to proper temperature, it will be transferred to power press for forging. Three sets of molds and fixtures are kept as drawings before hammering.
Hardening
The forged rail clips are passed through a quenching oil tank in a conveyor belt for a period of 12 minutes at a temperature of 70℃. The maximum time required for the rod to be removed from the heating furnace to be immersed in the quenching oil time (including forming) is 20 seconds. Cleaning quenching oil bath, and then, checking the Dimensional accuracy and quench hardness of rail clips.
Tempering
After quenching, the elastic rail clips are tempered at 400-500℃ for a period of 55-60 minutes, which can achieve appropriate toughness in the spring.
Inspection
Every rail clip is put through strict quality controls before delivery, such as fatigue test, hardness test and load test, etc. All inspections will go through according to requirements from different customers.
Packing
Surface treatment is a necessary link before packaging if customer has requirement. There is a range of surface treatments to meet the needs of varying applications, such as plain (oiled), Oxide black, color painting or other methods according to customer requirements. For package, a lot of packing methods are suitable for fast rail clips, woven bags is one of the common packing method.
