[0016] Another technical solution proposed by the present invention is to provide an implementation method of a bending forming device for producing a fan outer cylinder, comprising the following steps:

[0017] S1: Place the fan plate to be processed on the main box, and fix the two ends of the fan plate to be processed with a concave plate, and use the airflow generated by the main air pump to extend the telescopic bronchus to achieve downward movement of the reinforcement tube;

[0018] S2: When the fan plate to be processed is bent by the reinforcing tube, the fan plate to be processed gradually becomes U-shaped, and then the stabilizing box is pushed to make the insert tube and the piston rod plug into each other, and the gas in the insert tube will enter the stabilizing telescopic side rod, so that the stabilizing telescopic side rod is extended, so that the stabilizing ring fixes the U-shaped fan plate;

[0019] S3: When the stabilizing telescopic side rod is extended to the maximum length, the gas in the intubation tube will enter the telescopic short tube, causing the stabilizing telescopic side rod to move downward as a whole;

[0020] S4: When the size of the fan plate to be processed is smaller than the size of the forming groove, the fan plate is placed in the forming groove and fixed with a clamp to bend the fan plate. When the fan plate is bent to a certain extent, one end of the fan plate will squeeze the pad.

[0021] S5: The extrusion pad will compress the compressed air tube, and the gas in the compressed air tube will enter the telescopic straw, causing the auxiliary inner rod to move along the inside of the auxiliary tube, causing the angle of the splint to change. At this point, all implementation steps are completed.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention proposes a bending forming device and method for producing a fan outer cylinder. In the prior art, it is difficult to fix the fan plate more stably during processing and fixing, and if it is fixed too tightly, the processed product will be damaged. The present invention places the fan plate to be processed on the main box body, and uses a concave plate to fix the two ends of the fan plate to be processed. When the fan plate contacts the soft air cushion, the gas in the soft air cushion will be squeezed into the telescopic top rod, and the fan plate will be fixed more firmly. In addition, during the processing, as the bending degree of the fan plate continues to increase, the pulling force at both ends of the fan plate increases accordingly. When the rated force is reached, the strong magnetic disk separates from the concave plate to prevent the fan plate from being damaged due to excessive force, thereby improving product quality.

[0024] 2. The present invention proposes a bending and forming device and method for producing a fan outer cylinder. In the prior art, after bending and forming, the fan plate will recover, resulting in low forming quality. However, in the present invention, when using a reinforcing tube to bend the fan plate to be processed, the fan plate to be processed gradually becomes a U-shape, and then the stabilization box is pushed to make the insert tube and the piston rod plug into each other, and the gas in the insert tube will enter the stabilization telescopic side rod, so that the stabilization telescopic side rod is extended, so that the stabilization ring fixes the U-shaped fan plate, and when the stabilization telescopic side rod is extended to the maximum length, the gas in the insert tube will enter the telescopic short tube, so that the stabilization telescopic side rod moves downward as a whole, pulling the formed fan plate, preventing the formed fan plate from recovering, and improving the forming quality.

[0025] 3. The present invention proposes a bending and forming device and method for producing a fan outer cylinder. In the prior art, when the sizes of the processed fan plates are different, it is inconvenient to fix them, and the angle of the tangent surface of the fan plate changes at any time during the bending process, and the stability decreases accordingly; while in the present invention, when the size of the fan plate to be processed is smaller than the size of the forming groove, the fan plate is placed in the forming groove, and the fan plate is bent by fixing it with a splint. At the same time, when the fan plate is bent to a certain extent, one end of the fan plate will squeeze the pad, and the squeezing pad will squeeze the compressed air pipe, and the gas in the compressed air pipe will enter the telescopic suction pipe, so that the auxiliary inner rod moves along the inside of the auxiliary pipe, causing the angle of the splint to change, so that the splint can change with the change of the tangent angle, thereby improving the stability of the splint to the workpiece.
