Perforating device

Abstract

The invention discloses a punching device, and relates to the technical field of punching, the punching device comprises a main body provided with a power unit, the main body is connected with a strip-shaped part, the strip-shaped part is provided with a belt wheel transmission mechanism and a drill bit, and the power unit drives the drill bit to rotate through the belt wheel transmission mechanism. According to the punching device, the strip-shaped part is arranged to drive the belt wheel transmission mechanism and the drill bit to extend into the root of the narrow end face of the printing machine roller shaft, and finally the power unit on the main body drives the drill bit to rotate, so that a broken roller shaft, a bearing, a screw head or the end face of the roller shaft can be punched, and therefore in a narrow space, the punching efficiency is improved. Under the condition that manual operation with hands or other tools cannot be achieved, the operation of punching holes or drilling broken screw heads in narrow gaps is achieved, the large work type that broken parts are dismantled after machine roll shafts are completely dismantled is avoided, the work efficiency can be greatly improved, and the maintenance cost can be greatly reduced.
