Embodiment 1

[0019] Embodiment 1: with reference to attached Figure 1-6 . An embedded high-manganese steel frog structure, which includes a high-manganese steel frog, and the high-manganese steel frog spacer plate 1 is an outwardly convex structure, and is intermittently distributed in frog bolt holes 3; the high-manganese steel frog The spacer iron 2 at the heel end of the fork is a solid structure; the outer walls 5 on both sides of the frog made of high manganese steel have uniform wall thickness, and form a box-shaped structure with the transverse reinforcement 4 . The high manganese steel frog transverse reinforcement 4 is 60-100mm wide, the upper side is connected to the rail top, and the lower side ensures the space for setting the riser. Its manufacturing process belongs to the prior art and will not be described here.

Abstract

The invention relates to an embedded high manganese steel frog structure with the advantages of uniform wall thickness, stability and reliability in internal quality of a frog, high overall strength, casting enhancement, good machining performance, simplicity and reliability in assembly process and long service life of the frog. The structure comprises a high manganese steel frog; high manganese steel frog spacing boards are convex in structure and discontinuously distributed in frog bolt holes; high manganese steel frog heel end spacing iron has a solid structure; and two outer walls of the high manganese steel frog are uniform in thickness and form a box-type structure together with cross ribs. The invention has the advantages that 1, the structure is simple in design, easy to cast and good in machining and assembly; 2, comprehensive feeding in the casting process can be realized, the abrasion resistance of a point rail or a wing rail is enhanced, and the service life of the frog is prolonged; 3, the frog spacing boards are uniformly distributed in the bolt holes, and the convex structure is matched with the rail web of a steel rail, so that the overall stability of the frog is further enhanced; and 4, the two outer walls of the frog do not have hollowness and are uniform in thickness, and the heel end spacing iron has the solid structure, so that the overall strength of the frog is effectively improved.

Description

technical field [0001] The invention relates to a frog that not only has uniform wall thickness, stable and reliable internal quality, and good overall strength, but also has enhanced casting, good machining performance, simple and reliable assembly process, and long service life of the frog. At the same time, it has operability and intermittent type The utility model relates to an embedded high manganese steel frog structure with convex partition plates, which belongs to the field of high manganese steel frog manufacturing. Background technique [0002] The core rail and wing rail of the embedded high manganese steel frog are integrally cast from high manganese steel, which realizes the same material and the same service life, and the top surface of the rail is subjected to explosive pre-hardening treatment, which improves the initial hardness of the driving surface and enhances the fatigue resistance of the frog. Abrasiveness; After the two sides of the frog are assembled ...
