Knurling roller

The invention relates to the technical field of steel roller knurling devices, in particular to a knurling roller. Existing knurling rollers are generally of an integral type, and figures can not be replaced freely. The figures only can be replaced together with roller bodies due to abrasion of the figures after a long time of using, so that material is wasted. The knurling roller comprises a roller body. A roller sleeve is arranged outside the roller body. The roller sleeve is provided with a figure. Four fixing pins are evenly distributed on the outer edges of the left side face and the right side face of the roller body. The fixing pins are provided with rotation blocks. A silica gel seal ring is arranged between the roller body and the roller sleeve. The improved knurling roller is simple in structure and convenient to replace. The trouble of integral replacement is avoided. The cost is effectively reduced. The production efficiency is improved.
