Description
Technical Field
The invention relates to the field of steel rolling, in particular to a method for processing a porous roller.
Background
A universal technology for rolling steel rail features that the rollers of steel rail cogging mill include two rollers, upper and lower rollers. The upper roller and the lower roller form a closed hole pattern, and the steel rail is rolled through the closed hole pattern. The pass of the heavy rail BD2 roller comprises five passes which are two deep-cut holes, two extended holes and a pilot hole respectively, each roller comprises three closed passes and two open passes, the deep-cut holes and the extended holes form closed passes by the open passes and the closed passes, and the pilot hole forms closed passes by the two open passes, as shown in FIG. 1.
The machining method of the roller pass of the cogging mill comprises a forming cutter machining method and a numerical control machine tool machining method. The forming cutter machining method is characterized in that the roller is machined and formed at one time through the forming cutter, a final pass is formed on the roller, the pass to be machined on the roller comprises a plurality of rail-shaped holes, and the shape of the forming cutter is matched with the pass to be machined on the roller, so that each rail-shaped hole can be integrally and simultaneously machined through the forming cutter. Because the cutter body of the forming cutter is longer, the contact area between the forming cutter and the roller is not uniform, the stress of each position of the pass on the roller is not uniform, the deviation of the actual cutting amount of each position and the design value is larger, and the surface quality of a single rail-shaped hole in the machined pass is poorer. In order to improve the surface quality as much as possible, the feeding amount of the forming cutter needs to be reduced as much as possible at the later stage of the method, so that the overall production efficiency is low.
The numerical control machine tool machining method is characterized in that a roller is machined and formed at one time through a cutter of the numerical control machine tool, and the roller rotates at a high speed during machining of the numerical control machine tool, and the other roller cannot be arranged at the upper end of the roller, so that only a single-roller machining mode can be adopted. The cutter of the numerical control machine tool is used for respectively processing each rail-shaped hole in the overall hole pattern, rather than simultaneously processing the rail-shaped holes integrally in the forming cutter processing method, so that the accumulated error is large, the position accuracy of the processed hole pattern is poor, the matching of the closed hole patterns formed by a group of rollers is poor, and rail-shaped hole dislocation often occurs.
