The relationship between rail clip fasteners and shrapnel

Mar 13, 2023|

We all know that track clips are important railway accessories, but the clips must be used in combination with other railway accessories to play a role. When the clip buckles work, they mainly use the bending deformation properties of the material, and the processing is relatively simple. , and the cost is often low, but because the holes are opened for bolt fastening, stress concentration is prone to occur in this part, and the surface bending moment is the place where the section is weakened. The arched shrapnel fasteners developed in my country in the early stage were found to be easy to break when the bolts were tightened during use. The vibration generated when the train passed was easy to loosen the shrapnel, and some nuts even pulled out from the bolts. In addition, the gauge baffle plate is easy to climb to the bottom of the rail under the action of vibration, causing the gauge to expand, and shrapnel fasteners are no longer used on other track lines.

The buckle buckle uses the bending deformation performance of the material and the torsional deformation performance of the material (especially the circular cross-section spring) when working, so the elasticity is generally good, and there is basically no cross-section weakening, so the utilization rate of the material is high. , On the conventional line, it is generally hoped that the buckle has a large buckle pressure and good elasticity. In this regard, the elastic strip fastener has obvious advantages. At present, most of my country's railways and other rail transits use elastic buckle parts.

The above is the relationship between spring clips and clip fasteners shared by clip fastener manufacturers. I hope you can use this information to increase your understanding of clips and clip fasteners. Of course, if you are familiar with clips and clip fasteners If you still have doubts, want to get further understanding, or want to purchase various types and specifications of railway accessories, please contact our company.
