Description

Technical Field

[0001] The utility model relates to the technical field of railway vehicle equipment processing, in particular to a railway freight car side beam cutting process equipment. Background Art

[0002] Side beams are an essential component of railway freight cars, carrying the primary load-carrying and supporting functions. Typically, side beams are made from channel steel, a process that includes scribing, cutting the ends with gas welding, beveling, and grinding with an angle grinder. Traditional production methods have numerous shortcomings, resulting in low production efficiency and inconsistent product quality.

[0003] In the existing processing method, the side beam needs to be placed on a rack first, and then a tape measure is used to measure the length required by the drawing, and a line is marked. The cutting line is extended to each side of the side beam using a template. After completing these preparatory work, the operator will use a gas welding torch to cut along the marked line, and then cut the required groove on the side. The cut edge and oxide scale are polished with a grinding wheel.
