Description

Introduction of Railway Track Interval Switch Tie Bar

The switch tie bar is a key component in the railway transportation system, used to connect different tracks and switch the direction of train movement. By connecting and supporting the switch plate and sleepers, it enables the switch to operate normally and ensures that trains can smoothly and safely switch between tracks. The switch tie bar is typically made of high-strength steel to ensure its load-bearing capacity and service life.

Features of Railway Track Interval Switch Tie Bar

Firstly, the use of switch tie bars is extremely common, and they can be found in almost every railway transportation system.
By connecting and supporting the switch plate and sleepers, it enables the switch to operate normally and ensures that trains can smoothly and safely switch between tracks.
The switch tie bar must have high strength and wear resistance to withstand long-term train operation and harsh environmental conditions.
Secondly, the switch tie bar is usually made of high-strength steel to ensure its load-bearing capacity and service life.
The steel undergoes precise processing and heat treatment to give it excellent mechanical properties, such as strength, hardness, and toughness.
These characteristics enable the switch tie bar to withstand the huge wheel pressure and impact force when trains pass through, while resisting external factors such as climate and temperature changes.
In addition, the switch tie bar also needs to have high precision and durability.
It must have precise dimensions and shapes to ensure that the switch can operate smoothly and avoid accidents such as derailment.
At the same time, the switch tie bar also needs to have corrosion resistance and wear resistance to ensure that it does not deform, break, or fail during long-term use.

Production Process Requirement of Railway Track Interval Switch Tie Bar

Firstly, high-quality steel is selected as the raw material and undergoes heat treatment to increase its strength and hardness.
Then, advanced mechanical processing equipment is used to precisely cut and drill the steel to make the various components of the switch tie bar.
Finally, the processed components are carefully assembled and inspected to ensure that the product meets the standard specifications.
The design of the switch tie bar takes into account various factors, such as train wheel pressure, train speed, and switch type.
For different conditions, the switch tie bar will have different design parameters and structural forms.
For example, in sections where high-speed trains operate, the switch tie bar needs higher strength and rigidity to cope with greater wheel pressure and impact force.
To ensure the quality and safety performance of the switch tie bar, a strict quality inspection process is essential.
Quality checks and tests are conducted at every stage from raw materials to finished products.
These inspections include material mechanical property tests, dimensional accuracy checks, and corrosion resistance tests.
Only products that pass all quality inspections can be sold and put into use.
