The invention discloses a simple bending device for an aluminum row, and solves the problems that in the prior art, during the on-site aluminum row processing process, the working efficiency is low, the bending quality is poor, and the like. The simple bending device is characterized in that an upper module (4) is mounted at the top of a bracket which comprises two guide rods (2) vertically and fixedly mounted on a base (1) and a horizontal connecting rod; a bearing disc (5) used for mounting a lower module (3) is arranged between the two guide rods (2); sleeves (7) which are mounted on the guide rods (2) on the two sides in a sliding and sleeving manner are arranged at the two ends of the bearing disc (5); a locating sleeve (13) is arranged in the central position of the bottom surface of a bearing plate (11); module baffle plates (12) are arranged in front of and at the back of the bearing plate (11); the lower module (3) is placed on the bearing plate (11) of the bearing disc (5); a hydraulic jack (6) is arranged in the central position of the base (1); and the head of a lifting rod (8) of the hydraulic jack is inserted in the locating sleeve (13). The simple bending device has the advantages that the combination is simple, the utilization is convenient, the working efficiency is high, and the like, the application is not limited by the working environment, and the device can be popularized and applied to maintenance of a distribution transformer in the power industry.
