Spring fastener manufacturers introduce the importance of spring quality

The railway rail is a component that supports the direction of the locomotive and the locomotive, and the rail is fixed on the sleeper of the ballast bed through elastic fasteners.

The buckle part of the elastic fastener is mainly the elastic strip, which generates buckle pressure on the rail through the bending and twisting deformation of the elastic strip, to ensure the reliable connection between the rails for a long time, to maintain the integrity of the rail as much as possible, and to prevent the rail from moving The vertical and horizontal movement of the sleeper ensures the normal gauge, thereby ensuring the safety of the rail vehicle. In addition, since the contact between the train wheel and the rail is a rigid contact, vibration is inevitable, and the special elastic structure of the elastic strip can also absorb the impact energy generated when the vehicle passes by, so as to achieve the effect of shock absorption. The elastic strip works under repeated alternating stress. It bears various effects such as bending, torsion, fatigue and corrosion. When the vehicle passes, it also bears a high instantaneous impact load, so the performance requirements for the elastic strip are very strict. .

With the increase of the axle load of railway locomotives and the increase of train speed, as well as the development of urban rail transit and subway, railway clips, as a key link of track structure, are constantly developing and their importance is becoming more and more attention of all countries. my country is a vast country with great differences in climate, transportation conditions and regions. It needs various elastic bars with different performance requirements to meet the requirements of different tracks and different track types. For example, on conventional lines, elastic strips with high buckle pressure and good elasticity are required to meet the needs of heavy-duty and high-speed lines; while in viaduct track seamless lines, in order to reduce the interaction force between rails and bridges, fasteners are required The resistance is small, and the elastic strips are guaranteed to have sufficient elasticity, that is, the rigidity of the elastic strips is low enough to ensure that the buckle pressure loss caused by the compression of the under-rail cushion is small when the train passes, and the fasteners do not loosen.
