The dual-servo pure electric bending machine according to claim 1, characterized in that: Four rotating wheels are fixedly connected to the lower end of the bending equipment body (1); the rotating platform (609) is rotatably connected to the circumferential surface of the swing seat (608); and the first circular groove (612) is connected to the second circular groove (613).

9. The dual-servo pure electric bending machine according to any one of claims 1 to 8, characterized in that: The clamping box (605) and the transmission gear (604) rotate in cooperation with each other through two swinging rods (603), so that the transmission gear (604) can drive one end of the clamping box (605) through the swinging rod (603).

10. The working method of the dual-servo pure electric bending machine according to claim 9, characterized in that: The steps include: S1: Workpiece side bending preparation stage Workpiece positioning: Slide the workpiece into the butt tube and through the swing seat to place it in the appropriate position. Dimension measurement: Workers use measuring equipment to measure and judge the size of the workpiece to ensure that the position of the workpiece meets the processing requirements. Servo cylinder action: Start the servo cylinder to drive the sliding frame to move, so that the two clamping plates can clamp the workpiece. Workpiece Fixing: The workpiece is fixed in the butt tube through the clamping action of the clamping disc in preparation for side bending. Servo motor action: The servo motor starts, driving the transmission gear to rotate, and then drives the clamping box to move through the swing rod, so as to achieve precise position adjustment of the workpiece and provide precise position control for side bending. S2: Workpiece side bending execution stage Transmission gear rotates: The transmission gear continues to rotate, so that the prying rod on the rotating table can press against the workpiece. Side bending of workpiece: The side bending of the workpiece is achieved by applying force through the lever. Limit control: After side bending, the limit bar limits the turntable to control the side bending curvature and position of the workpiece. Function of the swing seat: The rounded corner design on the surface of the swing seat helps to effectively bend the workpiece and further control the side bending angle. S3: Auxiliary Operations and Equipment Movement Use of the placement box: The placement box on one side of the bending equipment body is used to temporarily place the workpiece to be processed, which is convenient for workers to take. Connecting plate fixation: The connecting plate fixes the placement box on the bending equipment body to enhance the load-bearing capacity of the placement box. Equipment movement: On the construction site, the bending equipment body can be moved to the working position by connecting the pull ring with a crane.
