Seamless rack rail and rolling mechanism and method thereof

The invention relates to a seamless rack rail and a rolling mechanism and method thereof, the rolling mechanism comprises a tooth groove roller, a bottom roller and two side rollers, the tooth groove roller and the bottom roller are oppositely arranged up and down, the two side rollers are symmetrically arranged left and right, and an area defined by the tooth groove roller, the side rollers and the bottom roller is used for continuously rolling a rack rail blank to form the seamless rack rail. According to the seamless rack rail rolling mechanism, continuous production of seamless rack rails can be achieved, the production efficiency is improved, cutting machining technologies such as gear milling and gear shaping are avoided in the rolling production process, noise is low, pollution is small, the production labor condition is improved, extra repolishing or recoating cost is not needed, and the production cost is reduced. According to the seamless rack rail rolling mechanism, the machining mechanism is easy
