Apparatus for manufacturing a rail , method for manufacturing a rail and rail

摘要

The present invention, by performing the cold rolling process in the up, down, left, and right forward of the processed material, and at the same time improving the processing efficiency of the cold rolling treatment can be to reduce the size of the size of the apparatus, to the processing surface is very good after machining of the rail separate after the machining process is not necessary at all it is an object to provide a rail processing apparatus, processing method rail and rail to reduce the manufacturing cost.; Rail machining apparatus according to the present invention for achieving the above object is pivotally mounted to rotate around the center of the horizontal to the top and bottom side of the frame, a plurality formed into individual shapes corresponding to the respective forming process of top and bottom of the material being molded of the upper and lower compression roller and; Rotatably installed to rotate around the center of the vertical on the left and right sides of the frame, it is disposed between the respective upper and lower pressure roller, a plurality of right and left pressing is formed to the individual shape that corresponds to the respective forming process of right and left sides of the material being molded in the rail processing apparatus consisting of a roller,; Pressing gap adjusting unit for adjusting the pressing gap between the respective upper and lower pressure roller and each of the right and left pressing roller is provided on each of the upper and lower pressing rollers between the compression space and each of the right and left of the pressure roller and individually; Consists of a welding machine disposed on the outlet side of the frame, the pressing gap adjusting unit, or configured to manually adjust the compression space of each of the pressure roller by an adjusting bolt or the pressing gap adjusting unit based compression of each of the pressure roller by a predetermined program, characterized in that is configured to automatically adjust the gap.
