The invention relates to the technical field of railway track machining, and discloses an auxiliary device for bending and forming a railway track and capable of achieving reduction of indentation and damage. The auxiliary device comprises a bracket, and a mounting column is fixedly mounted on the inner wall of the bracket; and a sliding sleeve is fixedly mounted at the end, away from the bracket, of the mounting column, and a sliding rack is slidably connected with the interior of the sliding sleeve. According to the auxiliary device for bending and forming the railway track and capable of achieving reduction of indentation and damage, through asynchronous downward pressing of three pressing wheels, the pressing wheels on the two sides synchronously do relative motion while being pressed downwards, so that sliding friction is converted into rolling friction when the railway track is bent; the friction force on the railway track is greatly reduced; the indentation on the surface of the railway track and damage caused by large friction force are greatly reduced, and the whole face is bent; the rebound situation during bending is avoided, and the number of required bending times for a finished product is reduced; and the bending working efficiency is improved to a certain degree.
Description
technical field [0001] The invention relates to the technical field of railway track processing, in particular to a railway track bending and forming auxiliary device that reduces indentation and damage. Background technique [0002] With the continuous improvement of people's living standards, many people gradually walk out of the house. Most of them will choose high-speed trains. The price is moderate and fast. The rails can provide an extremely smooth and hard medium for the train wheels to roll on them with minimal friction, making people feel comfortable and saving energy, but the rails are usually not a straight rail, and sometimes it is necessary to fold the rails A certain degree of curvature. [0003] However, the existing bending equipment usually consists of two fixed rods plus a push rod, and the rail is bent into a certain angle under the push of the push rod. This method mainly focuses on the contact point during bending, and the contact point bears The frict...
