Embodiment Construction
[0021] The forming device of the second pressing process of the railway track spring bar includes a frame, a power source, an upper mold assembly and a lower mold assembly, the lower mold assembly includes two supporting rollers 1, the upper mold assembly includes two pressure rollers 6 and is located at two The pressure groove block 5 in the middle of the pressure roller 6, the two support rollers 1 and the two pressure rollers 6 of the upper mold assembly, and one pressure groove block 5 form a shaper structure. The upper mold assembly is connected with a pressure power source, and the pressure roller block 5 is connected to Independent pressure power source, the two pressure rollers 6 use the same pressure power source, or the two pressure rollers 6 use different pressure power sources.
[0022] The lower mold assembly includes a center support 2 and end supports 3 symmetrically arranged on both sides of the center support 2, and a positioning cylinder is arranged next to th...

The invention discloses a novel railway track elastic bar forming mould. The novel railway track elastic bar forming mould comprises a rack, a power source, an upper mould assembly and a lower mould assembly, wherein the lower mould assembly comprises two supporting rollers; the upper mould assembly comprises two pressure rollers and a pressure slot block positioned between the two pressure rollers; the two supporting rollers, the two pressure rollers of the upper mould assembly and one pressure slot block define an insertion tooth structure; the upper mould assembly is connected with a pressure power source; and a pressure rolling block is connected with an independent pressure power source. Compared with the prior art, the novel railway track elastic bar forming mould has the beneficialeffects that: not too great pressure is needed when the elastic bar is pressed to a parallel state from a V shape, so that tensile deformation is not generated; and when V shape is pressed into an inverted W shape, only bending force is generated while drawing force and tensile deformation are not generated, so that the elastic bar produced and formed by the novel railway track elastic bar formingmould is consistent in thickness, elastic force is uniform and materials are saved.
Description
technical field [0001] The invention relates to the field of railway tracks, in particular to a novel railway track spring strip forming die and processing technology. Background technique [0002] 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, effectively ensuring the reliable connection between the rails for a long time, maintaining the integrity of the rail as much as possible, and preventing the rail from Relative to the vertical and horizontal movement of the sleepers, the gauge is guaranteed to be normal, thereby ensuring the safety of rail vehicles. In addition, since the contact between the train wheel and the rail is a rigid contact, it is inevitable to gen...
