Perforating device for radiator machining

The utility model relates to the technical field of radiator machining, in particular to a punching device for radiator machining, which comprises a base, and supporting pads are mounted at four corners of the bottom of the base. The two movable clamping plates move mutually to clamp and fix the radiator body, and the fastening bolts are rotated to drive the movable pressing plates to descend to press and fix the two ends of the top of the radiator body. A servo motor is started positively and negatively to drive a second threaded rod to rotate to drive a movable block to move outside the second threaded rod so as to drive a punching device body to move for positioning, and a cleaning brush is pushed by a supporting rod to move at the top of a radiator body to clean scraps at the top of the radiator body after punching is completed. Therefore, the problems that a traditional punching device for radiator machining is inconvenient to fix in the punching process, so that deviation occurs in the punching process,
