Performance Characteristics Of SKL Rail Clip
High buckling pressure:
When the spring deformation is 13mm, a single clip can provide a buckling pressure of 2×10kN=20kN, which can effectively prevent the longitudinal and lateral movement of the rail relative to the sleeper, ensure the normal track gauge, and maintain the stability of the track.
Good elasticity:
The W-shaped design makes the spring clip have high elasticity, which can effectively absorb the impact energy generated by the passing of the train, reduce the vibration and noise of the track, and extend the service life of the track components.
High fatigue strength:
After strict heat treatment and quality control, SKL rail clip can withstand 5 million fatigue tests without breaking, and can work stably under long-term repeated alternating stress, ensuring the safety and reliability of the track.
Low maintenance cost:
Due to its reasonable structural design, under normal use conditions, SKL rail clip and screws and other components that match it are not easy to loosen, and the middle bend can also prevent the spring arm from plastic deformation, achieving maintenance-free or less maintenance, reducing the maintenance cost of railway operation.
Function of SKL Rail Clip
The SKL rail clip is a shear connection system commonly used in railway turnout connections. It uses advanced design concepts and process technologies to ensure firm connection and safe operation of railway turnouts. This clip system usually consists of SKL shear parts, spring washers, rubber washers, and bolts, which work together to enable the turnout to withstand the heavy pressure and running impact of the train.
The SKL rail clip is designed to provide high reliability and durability to meet the stringent requirements of the railway transportation industry. They are usually made of high-strength alloy steel, have excellent corrosion resistance and durability, and can be used for a long time in harsh climatic conditions without failure.
The installation of this clip system is relatively simple, usually only requiring the use of some basic tools and equipment. SKL rail clips are easy to maintain and replace, so damaged parts can be quickly replaced during maintenance and repair, reducing maintenance costs and downtime.
SKL Rail Clip Processing Procedures
Raw material: Premium grade spring steel sourced from a reliable and certified long term producer.
Shearing: The spring steel bar has to be sheared as per length required.
Heating: To forging temperature (950-1000 degrees Celsius), but over heating shall be avoided to check decarburization.
Forming: Proper heated bar is transferred to power press for forging.
Hardening: The forged rail clips are transferred to quenching tank. Dimensional accuracy and quench hardness of rail clips are checked before tempering.
Tempering: The rail clips are tempered at about 350 Celsius to achieve appropriate toughness in the spring.
Inspection: The products are customer required specification and design.
Scope of Applicable to SKL Rail Clip
Type of track:
It is suitable for the standard railway line and radius R300M lines, including different types of orbits such as ordinary railways, high -speed railways, and urban rail transit.
Type of steel rails:
It is mainly used for 50, 60kg/m steel rail lines, and can be used with the corresponding rail sleeper and fastening system to ensure the reliable connection between the rail and the sleeper.
Type of rail sleepers:
It can be applied to prestressed concrete sleepers, prestressed wide concrete sleepers, and overall road beds in a straight line, etc.
