[0024] The clamping mechanism includes a first support base 11, a clamping block 12, and a clamping cylinder 13. The first support base 11 is mounted on the upper surface of the base 1, and the clamping block 12 is positioned directly above the first support base 11. The tail end of the clamping cylinder 13 is connected to the lower surface of the top end inside the U-shaped frame 2, and the telescopic end of the clamping cylinder 13 is connected to the upper surface of the clamping block 12. The clamping block 12 engages with the top of the U-shaped frame 2 via guide posts. V-shaped grooves are provided on the upper surface of the first support base 11 and the lower surface of the clamping block 12. The V-shaped slot is used to better clamp copper rods of different sizes. When conveying copper rods, the lower clamp 3 and upper clamp 4 of the conveying mechanism clamp the copper rods forward. Then, the first support 11 and clamping block 12 of the clamping mechanism clamp the copper rods. The lower clamp 3 and upper clamp 4 are released and retracted. After the lower clamp 3 and upper clamp 4 are re-clamped, the first support 11 and clamping block 12 are released. The above steps are repeated to achieve feeding. During processing, the copper rods are clamped by the clamping mechanism.

[0025] The bending mechanism includes a fixed mold 14, a movable mold 15, and a bending forming cylinder 16. The fixed mold 14 is bolted to the base 1. The movable mold 15 is positioned directly above the fixed mold 14. The movable mold 15 is connected to the top of the U-shaped frame 2 via a guide column. The bending forming cylinder 16 is connected to the top of the U-shaped frame 2. The telescopic end of the bending forming cylinder 16 is connected to the upper end face of the movable mold 15. A lower mold 20 is provided on the lower surface of the fixed mold 14, and an upper mold 21 is provided on the lower surface of the movable mold 15. The lower mold 20 has an arc-shaped groove 22, and the upper mold 21 has an arc-shaped punch 23. The arc-shaped punch 23 cooperates with the arc-shaped groove 22. A rod positioning groove 24 with a semi-circular cross section is provided on the lower surface of the arc-shaped punch 23 and the middle position of the arc-shaped groove 22. Through the cooperation of the arc-shaped punch 23 and the arc-shaped groove 22, the copper rod is bent and formed in the rod positioning groove 24.

[0026] A cutting mechanism is provided on the lower surface of the top of the U-shaped frame 2, located between the clamping mechanism and the bending mechanism. The cutting mechanism includes a second support seat 17, a cutting cylinder 18, and a cutter 19. The second support seat 17 is located on the upper surface of the base 1.

[0027] Working Method and Operating Principle: Based on the dimensions of the copper rod to be processed, select a suitable bending die and install it onto the bending mechanism. Place the copper rod on the conveying mechanism and clamp it in place using the lower clamp 3 and upper clamp 4. Control the operation of the push-pull cylinder 6, which moves the lower clamp 3, thus pushing the copper rod forward. The end of the copper rod is clamped by the clamping mechanism. The upper clamp 4 of the conveying mechanism opens, the conveying mechanism pushes backward, the upper clamp 4 clamps again, and the clamping mechanism releases, thus conveying the copper rod. When the front end of the copper rod reaches the bending mechanism, the pipe conveying mechanism stops working. At this time, the clamping cylinder 13 of the clamping mechanism pushes the clamping block 12 to tightly clamp the copper tube, ensuring the smooth progress of the bending process. Then, the bending forming cylinder 16 is controlled to work, pushing the movable mold 15 downwards, which in turn moves the upper mold 21 downwards, pressing the copper rod between the lower mold 20 and the upper mold 21. The copper rod is bent and formed through the cooperation of the arc-shaped punch and arc-shaped die. After bending, the piston rod of the cutting cylinder 18 pushes downwards, and the bent portion is cut off by the cutter 19. Subsequently, the feeding continues through the cooperation of the conveying mechanism and the clamping mechanism, and the bending mechanism performs the bending forming. The operator can also change the upper mold 21 and the lower mold 20 to obtain copper rods with different bending arcs and cross-sectional shapes. This utility model has a reasonable structure. Automatic feeding can be achieved through the conveying mechanism and the clamping mechanism, eliminating the need to cut the copper rod first and then manually feed it, greatly improving processing efficiency and reducing labor costs. Furthermore, the clamping mechanism ensures that the copper rod will not shift during the bending process, thus guaranteeing processing accuracy.
