The second spur gear 209 is fixedly connected to the bending motor 208. The first spur gear 204 meshes with the second spur gear 209. Driving the bending motor 208 drives the second spur gear 209 to rotate through the first spur gear 204, causing the first support plate 201 on the first shaft 202 to move upward for bending. At the same time, the first reel 203 rotates to wind the steel wire rope 211 on the second reel 210, and the second reel 210 rotates to drive the bending plate 206 to bend upward through the second shaft 205.

[0035] As Figures 4-7As shown in the figure, the pressing mechanism 3 includes a pressing motor 301, a first bevel gear 302, a screw rod 303, a second bevel gear 304, a second support plate 305, a third shaft rod 306, a third bevel gear 307, a pressing block 308, a pressing plate 309 and a U-shaped frame 310. The pressing motor 301 is installed in the pressing groove 101 on the frame 1. The first bevel gear 302 is fixedly connected to the pressing motor 301. The screw rod 303 is rotatably connected in the pressing groove 101 on the frame 1. One end of the screw rod 303 is fixedly connected to the second bevel gear 304. The first bevel gear 302 meshes with the second bevel gear 304. The third shaft rod 306 is rotatably connected in the pressing groove 101 on the frame 1. The third shaft rod 306 is connected to the second support plate 305. One end of the third shaft rod 306 is fixedly connected to the third bevel gear 307. The third bevel gear 307 meshes with the second bevel gear 304. The pressing block 308 is hinged to the second support plate 305.

One end of the U-shaped frame 310 is hinged to the lower part of the pressing plate 309.

[0036] The pressing block 308 is arc-shaped, and the arc of the forming die 502 is the same as that of the pressing block 308.

[0037] The punching mechanism 4 includes a mounting plate 402, a rotating shaft 401, a punching cylinder 403, a lower pressing plate 404 and a punching die 405. The rotating shaft 401 is rotatably connected to the frame 1. The mounting plate 402 is fixedly connected to the rotating shaft 401. The punching cylinder 403 is installed on the mounting plate 402. The telescopic part of the punching cylinder 403 is fixedly connected to the lower pressing plate 404. The telescopic end of the punching cylinder 403 is fixedly connected to the punching die 405.

[0038] The forming assembly 5 includes a forming cylinder 501 and a forming die 502. The forming cylinder 501 is installed on the mounting plate 402. The telescopic end of the forming cylinder 501 is fixedly connected to the forming die 502.

[0039] During operation, first place the fitting on the bending mechanism 2 and the pressing mechanism 3. Then, start the punching cylinder 403 to move downward, and punch the fitting through the stamping die 405. Start the forming cylinder 501 to move the forming die 502 downward. At the same time, start the pressing motor 301 and the bending motor 208 to rotate forward. The forward rotation of the pressing motor 301 drives the first bevel gear 302 to rotate. The rotation of the first bevel gear 302 drives the second bevel gear 304 and the third bevel gear 307 to rotate. The rotation of the third bevel gear 307 drives the second support plate 305 on the third shaft rod 306 to move upward. At the same time, the second bevel gear 304 drives the screw rod 303 to rotate. The rotation of the screw rod 303 drives the pressing plate 309 and the pressing block 308 to move upward through the U-shaped frame 310 for bending. Through cooperation with the forming die 502, the left side of the fitting is pressed to form a curved bend. At the same time, the forward rotation of the bending motor 208 drives the first straight gear 204, the first winding wheel 203, and the first shaft rod 202 to rotate through the second straight gear 209. The rotation of the first shaft rod 202 moves the first support plate 201 upward. At the same time, the first winding wheel 203 rotates to wind the steel wire rope 211, causing the second winding wheel 210 to drive the second shaft rod 205 to rotate. The rotation of the second shaft rod 205 moves the bending plate 206 upward to bend the front and back sides of the fitting. At the same time, the first torsion spring 207 twists. When the fitting is punched and bent into shape, drive the punching cylinder 403 and the forming cylinder 501 to move upward to reset. At the same time, drive the pressing motor 301 and the bending motor 208 to rotate in reverse. The reverse rotation of the pressing motor 301 drives the first bevel gear 302, the second bevel gear 304, and the third bevel gear 307 to rotate. The second bevel gear 304 drives the screw rod 303 to rotate in reverse. The rotation of the screw rod 303 drives the pressing plate 309 and the pressing block 308 to reset through the U-shaped frame 310. The rotation of the third bevel gear 307 drives the second support plate 305 on the third shaft rod 306 to reset. At the same time, the reverse rotation of the bending motor 208 drives the first straight gear 204, the first winding wheel 203, and the first shaft rod 202 to rotate in reverse through the second straight gear 209. The first winding wheel 203 releases the steel wire rope 211. The first torsion spring 207 resets to drive the second shaft rod 205 and the second winding wheel 210 to rotate for reset. The second winding wheel 210 winds back the steel wire rope 211 released by the first winding wheel 203 for reset. Repeating this process realizes the function of punching the fitting while also being able to perform curved bending and forming.

[0040] Example 2: On the basis of Example 1, as Figures 10-12As shown in the figure, it further includes a pressing mechanism 7. The pressing mechanism 7 includes a lower pressing frame 701, a tension spring 702, a sliding frame 703, a sliding rod 705, a pressing rod 706, a rotating rod 707 and a second torsion spring 708. The lower pressing frame 701 is slidably connected to the frame 1. The upper part of the pressing frame 701 is located below the lower pressing plate 404. The lower part of the lower pressing frame 701 is connected to the tension spring 702. The tension spring 702 is connected to the sliding frame 703. Three sliding grooves 704 are formed on the sliding frame 703. The sliding rod 705 is slidably connected in the sliding groove 704 of the sliding frame 703. The pressing rod 706 is hinged on the sliding rod 705. The pressing rod 706 is located in the clamping hole 103. Rotating rods 707 are symmetrically arranged on both sides of the pressing rod 706. The rotating rods 707 are rotatably connected to the frame 1. The second torsion spring 708 is sleeved on the rotating rod 707. One end of the second torsion spring 708 is connected to the pressing rod 706, and the other end of the second torsion spring 708 is connected to the frame 1.

[0041] When it is necessary to press and fix the fittings, the punching cylinder 403 moves downward to drive the lower pressing plate 404 and the stamping die 405 to move downward. The lower pressing plate 404 presses the lower pressing frame 701 downward. The lower pressing frame 701 drives the sliding frame 703 to move downward through the stretching of the tension spring 702. The downward movement of the sliding frame 703 drives the sliding rod 705 to move outward in the sliding groove 704 of the sliding frame 703. The outward movement of the sliding rod 705 drives the pressing rod 706 to turn upward to press and fix the fittings. At the same time, the second torsion spring 708 twists. After the fittings are punched and the arc is bent and formed, the punching cylinder 403 moves upward to drive the lower pressing plate 404 and the stamping die 405 to move upward and reset. At the same time, the reset of the tension spring 702 drives the lower pressing frame 701, the sliding frame 703 and the sliding rod 705 to reset. At the same time, the reset of the second torsion spring 708 drives the pressing rod 706 to reset, and the formed fittings can be taken out. Repeating this process realizes the function of automatically pressing and fixing the fittings.

[0042] Embodiment 3: On the basis of Embodiment 1, as Figure 8 and Figure 9 shown in the figure, it further includes a transmission mechanism 6. The transmission mechanism 6 includes an electric sliding frame 601, a slide rail 602, an electric slider 603, a rack 604 and a third spur gear 605. The electric sliding frame 601 is fixedly connected to the rear part of the frame 1. The slide rail 602 is arranged on the right side of the frame 1. The electric slider 603 is slidably connected to the electric sliding frame 601. The rack 604 is fixedly connected to the right side of the electric slider 603. The lower part of the rack 604 is slidably connected to the slide rail 602 through a slider. The third spur gear 605 is fixedly connected to the rotating shaft 401. When the rack 604 moves forward, it meshes with the third spur gear 605. When the rack 604 resets, it also meshes with the third spur gear 605.

[0043] Drive the electric slider 603 to move forward. The electric slider 603 drives the rack 604 to move forward. The forward movement of the rack 604 meshes with the third spur gear 605 on the rotating shaft 401, causing the third spur gear 605 to rotate and drive the rotating shaft 401, the mounting plate 402, the stamping mechanism, and the forming assembly 5 to rotate 90°. This makes the stamping mechanism and the forming assembly 5 no longer located above the pressing mechanism 3 and the stamping hole 104, facilitating the automatic feeding of the feeding mechanism 8. When the electric slider 603 drives the rack 604 to move backward, the backward movement of the rack 604 meshes with the third spur gear 605 on the rotating shaft 401, causing the third spur gear 605 to rotate and drive the rotating shaft 401, the mounting plate 402, the stamping mechanism, and the forming assembly 5 to reset, so that the stamping mechanism and the forming assembly 5 are located above the pressing mechanism 3 and the stamping hole 104, enabling the punching and arc bending forming of the fittings.

[0044] Embodiment 4: On the basis of Embodiment 1, as Figure 9 shown, it further includes a feeding mechanism 8. The feeding mechanism 8 includes a material storage rack 801, a feeding cylinder 802, and a suction cup rack 803. The material storage rack 801 is fixedly connected to the frame 1. The feeding cylinder 802 is fixedly connected to the lower part of the electric slider 603. The telescopic end of the feeding cylinder 802 is fixedly connected to the suction cup rack 803. Suction cups are symmetrically arranged at the lower part of the suction cup rack 803.

[0045] When automatic feeding is required, drive the feeding cylinder 802 to move downward to suck out one fitting through the suction cups on the suction cup rack 803. When one fitting is sucked out, the feeding cylinder 802 drives the suction cup rack 803 to reset. Then drive the electric slider 603 to drive the feeding cylinder 802, the suction cup rack 803, and the rack 604 to move forward. The forward movement of the rack 604 meshes with the third spur gear 605 on the rotating shaft 401, causing the third spur gear 605 to rotate and drive the rotating shaft 401, the mounting plate 402, the stamping mechanism, and the forming assembly 5 to rotate 90°. This makes the stamping mechanism and the forming assembly 5 no longer located above the pressing mechanism 3 and the stamping hole 104. When the fitting sucked by the suction cup rack 803 on the feeding cylinder 802 is perpendicular to the pressing mechanism 3 and the stamping hole 104, drive the feeding cylinder 802 to move downward so that the suction cups on the suction cup rack 803 place the fitting on the pressing mechanism 3 and the stamping hole 104. Drive the feeding cylinder 802 to drive the suction cup rack 803 to reset. Then drive the electric slider 603 to drive the feeding cylinder 802, the suction cup rack 803, and the rack 604 to move backward. The backward movement of the rack 604 meshes with the third spur gear 605 on the rotating shaft 401, causing the third spur gear 605 to rotate and drive the rotating shaft 401, the mounting plate 402, the stamping mechanism, and the forming assembly 5 to reset, so that the stamping mechanism and the forming assembly 5 are located above the pressing mechanism 3 and the stamping hole 104, and punch and bend the fittings. Repeating this process realizes the function of automatic feeding.
