The working process of the aluminum rod bending device of the embodiment of the present invention is as follows: when the aluminum rod 26 whose end has been flattened needs to be bent, the operator first places the aluminum rod 26 on the two lower tires. The aluminum rod 26 is supported by the first lower mold 10 and the second lower mold 11. When placing the aluminum rod, it is necessary to keep the flattened part of its end substantially vertical, and then the operator presses the button. , the control system will control the linear cylinder 12 to work, and drive the support plate 13 and the finger cylinder 14 on it to move to the end of the aluminum rod 26 through the sliding table. When the movable limit block 15 contacts the fixed limit block 16, the finger The air cylinder 14 has moved in place, and then the finger air cylinder 14 works to clamp the flattened part of the aluminum rod 26, so that the aluminum rod 26 is adjusted to the processing posture that can be bent. The sliding table returns to the initial position;

After that, the control system will control the primary cylinder 4 to work, and the primary cylinder 4 drives the floating plate 5 downward. When the primary cylinder 4 moves to its limit stroke, the upper tire 6 connected to the bottom of the floating plate 5 will be pressed against its corresponding On the lower tire tool, that is, the upper tire tool 6 and the lower tire tool jointly press and fix the aluminum rod 26. After the work of the primary cylinder 4 is completed, the control system controls the two bending cylinders 7 to work synchronously at the same time, and the pressing block 8 goes down, The roller 9 on it directly contacts the aluminum rod 26 and bends it, and the straight aluminum rod 26 will be bent into a concave shape. During the bending process, the roller 9 and the aluminum rod 26 roll relative to each other. , so as to ensure that the pressure applied to the aluminum rod 26 is uniform, and the friction between the two is rolling friction, which can effectively reduce the scratches on the surface of the aluminum rod 26 during the bending process and ensure the quality of the product; bending operation After the end, the bending cylinder 7 is recovered, the primary cylinder 4 is recovered, and the upper tire 6 is returned to the initial position;

During the process of the upper tire 6 approaching the lower tire, the upper driving plate 21 provided on the upper tire 6 corresponding to the second lower tire 11 descends, and the upper inclined surface 22 at the bottom thereof will be in line with the lower driving plate 19. The lower inclined surface 20 is in contact, so that the longitudinal linear motion between the upper tire 6 and the lower tire will be converted into a horizontal linear motion under the action of the inclined plane, and the upper block 18 is driven to move horizontally relative to the lower block 17, and this movement will As a result, the distance between the upper block 18 in the second lower mold 11 and the first lower mold 10 becomes larger, and the aluminum rod 26 will also realize the bending operation under this spacing;

After the upper tire 6 goes up, under the action of the spring 24, the upper block 18 will return to the initial position, that is, the distance between the upper block 18 and the first lower tire 10 will return to the initial distance at this time, then the bending A certain gap will be formed between the vertical part of the rear aluminum rod 26 and the two lower tires, so as to prevent the bent aluminum rod 26 from being clamped on the two lower tires, so that the operator can smoothly fold it. The bent aluminum rod 26 is removed from the lower tire.
