[0042] Working principle:

[0043] The utility model does not require much debugging when in use:

[0044] Before starting the equipment, the worker first places the copper tube in the fixed lower mold 9-1; the vertical pushing servo motor 9-10 lifts the copper material to the position of the rotating tube bending rod core 5 and the height of the horizontal pushing mechanism 3. At this time, the copper tube should be close to the lower side of the rotating tube bending rod core 5.

[0045] The core rod horizontally pushes the servo motor 3-10 and the copper sleeve horizontally pushes the servo motor 3-11 in the horizontal pushing mechanism 3, and the copper sleeve 3-7 is pressed against the bottom of one end of the copper tube and the core rod 3-6 is inserted into the copper tube to keep it concentric. At this time, the vertical movement drive servo 3-1 works, driving the pressing mold 3-8 on the copper sleeve to cooperate with the core rod 3-6 and the fixed lower mold 9-1 to clamp the copper sleeve 3-7 and the copper tube to be processed.

[0046] When the copper material is sent to the working position of the rotating tube bending rod core 5 by the fixed lower mold 9-1 in the adjustment mechanism 9 and the horizontal pushing mechanism 3, the tube bending vertical clamping mechanism 7 drives the guide rod 2 7-5 to push up through the connecting rod 1 6-1 in the vertical lifting drive assembly 6, and the guide rod 2 7-5 then lifts the tube bending lower clamping mold 7-1 to the position of the copper material to be processed and clamps it.

[0047] When the copper material to be processed is clamped, the servo motor 8-1 drives the entire bending pipe vertical clamping mechanism 7 to rotate together through the fixed bracket 7-6 to bend the copper material into the required finished product angle; at this time, the core rod horizontal pushing servo motor 3-10 and the copper sleeve horizontal pushing servo motor 3-11 in the horizontal pushing mechanism 3 work, always pushing the copper sleeve 3-7 against the bottom of the workpiece and keeping the core rod 3-6 always in the same position of the pushing copper sleeve 3-6 and the center of the processed copper tube.

[0048] When the copper tube processing is completed and the material is unloaded manually, the servo motor in the servo rotary in-situ mechanism 4 rotates the vertical clamping mechanism 7 of the bent tube back to its original position. At the same time, the vertical lifting drive assembly 6 rotates back to its original position to lower the clamping mold 7-1 of the bent tube. At this time, one process is completed and waiting for the next process.

The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the idea of ​​the present invention belong to the protection scope of the present invention.
