[0040] Refer to Figures 1-3, An embodiment provided by the present utility model: an automatic hemming device for hardware parts, including:

[0041] An operating table 1, the operating table 1 is used to hold the whole, a top plate 2 is fixedly connected to the top of the operating table 1, an electric push rod 3 is fixedly connected inside the top plate 2, an upper mold 4 is fixedly connected to the output end of the electric push rod 3, and a lower mold 5 is fixedly connected to the top of the operating table 1;

[0043] A second support block 7, a turntable 13 is rotatably connected inside the second support block 7, a hand wheel 29 is fixedly connected to one end of the turntable 13, and a locking ring 14 is fixedly connected to the other end of the turntable 13;

[0044] A half ring 11, the half ring 11 is fixedly connected to one side of the second support block 7, and a limiting groove 12 is opened inside the half ring 11;

[0045] A limiting block 15, the limiting block 15 is fixedly connected to the outer wall of the locking ring 14, the limiting block 15 is slidably connected inside the limiting groove 12, the limiting block 15 is used to limit the locking ring 14, and the limiting component includes a limiting plate 10, the limiting plate 10 is fixedly connected to the outer wall of the connecting column 9, and the limiting plate 10 is rotatably connected inside the first support block 6;

[0046] Specifically, when installing the winding roller, first accurately insert one end of the winding roller into the connecting column 9 to ensure that the shape of the winding roller perfectly fits the shape of the connecting column 9 to ensure a stable connection. Subsequently, the other end of the winding roller is inserted into the second support block 7 through the precision slot on the second support block 7 to ensure accurate positioning. Next, rotate the hand wheel 29 to drive the rotation of the turntable 13, and the locking ring 14 rotates accordingly. The outer wall of the locking ring 14 is stably limited within the limiting groove 12, so that the locking ring 14 is closely fitted with the half ring 11, firmly wrapping and locking one end of the winding roller, thereby ensuring the stability of the winding roller during high-speed operation. After that, the coil is accurately passed through between the upper mold 4 and the lower mold 5, and the output end of the first motor 8 starts to drive the connecting column 9 to rotate, thereby driving the winding roller to rotate smoothly through the connecting column 9, ensuring that the coil can be wound smoothly and efficiently during the whole processing process.

[0047] Refer to Figure 4, a second support rod 20 is fixedly connected to the top of the operating table 1. One end of the second support rod 20 is rotatably connected to a second gear 21. Inside the second gear 21, a first pulley 22 is fixedly connected. A first support rod 16 is fixedly connected to the top of the operating table 1. One end of the first support rod 16 is rotatably connected to a first gear 18. Inside the first gear 18, a first connecting rod 17 is fixedly connected. One end of the first connecting rod 17 is rotatably connected to a first clamping plate 19. A third support rod 23 is fixedly connected to the bottom of the top plate 2. A second motor 24 is fixedly connected to one side of the third support rod 23. The output end of the second motor 24 is fixedly connected to a second pulley 25 and a second connecting rod 26. A belt 28 is arranged on the outer walls of the second pulley 25 and the first pulley 22. One end of the second connecting rod 26 is rotatably connected to a second clamping plate 27. The outer walls of the second gear 21 and the first gear 18 are meshed with each other;

[0048] Specifically, the output end of the second motor 24 drives the second pulley 25 and the second connecting rod 26 to rotate synchronously. The second pulley 25 transmits power to the first pulley 22 through the belt 28, causing the first pulley 22 to start rotating. Then, the second gear 21 drives the first gear 18 to rotate smoothly. The rotation of the first gear 18 acts on the first connecting rod 17, driving the first clamping plate 19 to rotate precisely. At the same time, the second connecting rod 26 drives the second clamping plate 27 to move coordinately. With the close cooperation of the first clamping plate 19 and the second clamping plate 27, the coil is evenly and stably pushed forward. Subsequently, when the first clamping plate 19 and the second clamping plate 27 are separated, the coil stops moving. At this time, the output end of the electric push rod 3 starts to work, driving the upper mold 4 to press downwards, so that the upper mold 4 and the lower mold 5 are tightly clamped together, thereby realizing the precise stamping and forming of the hardware part and completing the flanging operation of the hardware part. Immediately afterwards, the output end of the electric push rod 3 retracts, lifting the upper mold 4 to the initial position. The first clamping plate 19 and the second clamping plate 27 are closed again, continuing to push the coil forward for conveying, ensuring the high efficiency and smoothness of the entire processing process.

[0049] Working principle: When using this automatic hemming device for hardware parts, first, when installing the winding roller, insert one end of the winding roller into the connecting column 9. The shape of one end of the winding roller fits that of the connecting column 9. Subsequently, the other end of the winding roller is inserted into the second support block 7 through the slot on the second support block 7. Then, drive the turntable 13 to rotate through the handwheel 29. The locking ring 14 rotates through the turntable 13. The outer wall of the locking ring 14 is limited within the limiting slot 12, so that the cooperation between the locking ring 14 and the semi-ring 11 wraps and locks one end of the winding roller. Subsequently, the coil passes through between the upper die 4 and the lower die 5. The output end of the first motor 8 drives the connecting column 9 to rotate, thereby driving the winding roller to rotate. Then, the output end of the second motor 24 drives the second belt pulley 25 and the second connecting rod 26 to rotate. The second belt pulley 25 drives the first belt pulley 22 to rotate through the belt 28. The first belt pulley 22 drives the second gear 21 to drive the first gear 18 to rotate. The first gear 18 drives the first clamping plate 19 to rotate through the first connecting rod 17. The second connecting rod 26 drives the second clamping plate 27 to rotate, thereby driving the coil to move forward through the cooperation between the first clamping plate 19 and the second clamping plate 27. At the same time, when the first clamping plate 19 and the second clamping plate 27 separate, the coil stops. After the output end of the electric push rod 3 drives the upper die 4 to press down and engage with the lower die 5 to stamp and form the hardware part from the coil and hem the hardware part, the output end of the electric push rod 3 retracts to drive the upper die 4 to lift. Then, the first clamping plate 19 and the second clamping plate 27 rotate and close to drive the coil to continue to be conveyed forward.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
