Elastic clip fastening manufacturers tell you that in the related technologies, the turnouts of the railway speed-increasing passenger dedicated line adopt more buckling methods on the inner side of the basic rail, mainly shrapnel and pins, and wedge-shaped adjustment shrapnel buckling.

However, when using the shrapnel pin buckle method, due to the limitation of the height difference between the basic rail and the at rail, and the rear end of the shrapnel is limited by the bottom plate, the shrapnel is easily deformed too much, resulting in insufficient strength of the shrapnel and pins, and even damage and breakage. The manufacturer of Elastic clip fastening tells you that the wedge-shaped adjustable shrapnel buckle can avoid the shrapnel and pin breaking problems that occur in the shrapnel pin buckling method, and the buckle is durable, safe and reliable, but the added wedge block and its locking structure make installation and maintenance more cumbersome. And the installation method of using a sledgehammer to hit the wedge to raise the shrapnel will cause certain damage to the wedge.
Due to the operation characteristics of high smoothness, high safety and low maintenance workload of turnouts for passenger dedicated lines, it is difficult for shrapnel-pin type and wedge-shaped adjustment shrapnel to meet the use requirements.
Technical realization elements:
The manufacturer of Elastic clip fastening tells you that the present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a method for manufacturing an elastic clip for a turnout on a dedicated passenger line. The method is simple in process, easy to operate, and can ensure that the obtained elastic clip has accurate dimensions and stable and reliable buckling pressure.
Another object of the present invention is to provide an elastic clip manufactured according to the above manufacturing method.
According to the first aspect of the present invention, the manufacturing method of the elastic clip used for the turnout of passenger dedicated line comprises the following steps: the manufacturer of Elastic clip fastening tells you to perform a simmering bending on the cylindrical blank to obtain a roughly v-shaped piece to be pressed Stamping the piece to be pressed in a direction perpendicular to the plane where the piece to be pressed is located to obtain a stamped piece; performing secondary simmering on the outside of the stamped piece adjacent to its two free ends , to obtain the elastic clip, wherein the distance between the two ends of the elastic clip first decreases and then increases along its extending direction.
The elastic clip fastening manufacturer tells you that according to the manufacturing method of the elastic clip used for the turnout of the passenger dedicated line according to the present invention, by adopting the bending forming process, the size of the elastic clip can be made more accurate and the continuity of the metal fiber of the elastic clip can be maintained, thereby The fastening pressure of the elastic clip can be made durable, safe and reliable, and can meet the use requirements of the turnout of the passenger dedicated line.
