[0020] Please refer to Figures 1 - 4As shown in the figure, an embodiment of the present utility model provides a bending device for processing electrical appliance accessories, including a chassis 1. A central shaft 2 is rotatably connected to the middle of the top end of the chassis 1. A driving component for driving the central shaft 2 to rotate is arranged at the top end of the chassis 1. A top plate 3 is fixedly connected to the top end of the central shaft 2. A fixing plate 4 is fixedly connected to the outside of the chassis 1. A support column 5 is fixedly connected to the top end of the fixing plate 4. A receiving block 6 is fixedly connected to the top end of the support column 5. First limiting plates 7 and second limiting plates 8 for limiting the accessories are fixedly connected to the top ends of the receiving block 6 and the top plate 3 respectively. The driving component includes a servo motor 9 fixedly connected to the top end of the chassis 1. A transmission shaft 10 is fixedly connected to the output end of the servo motor 9. A transmission gear 11 is fixedly connected to the top end of the transmission shaft 10. A driven gear 12 meshing with the transmission gear 11 is fixedly connected to the outside of the central shaft 2. Elastic components for adjusting accessories of different sizes are fixedly connected to the inner sides of the first limiting plates 7 and the second limiting plates 8. The elastic components include fixing cylinders 13 fixedly connected to the inner sides of the first limiting plates 7 and the second limiting plates 8. A return spring 14 is fixedly connected inside the fixing cylinder 13. A sliding column 15 is fixedly connected to the side of the return spring 14 away from the inside of the fixing cylinder 13, and the sliding column 15 slides inside the fixing cylinder 13. A contact plate 16 contacting the accessory is fixedly connected to the side of the sliding column 15 away from the return spring 14. A support component is arranged between the chassis 1 and the top plate 3. The support component includes an annular groove 17 opened at the bottom end of the top plate 3. A slider 18 is slidably connected inside the annular groove 17. A support rod 19 is fixedly connected to the bottom end of the slider 18. The bottom end of the support rod 19 is fixedly connected to the chassis 1. Scale lines 20 for facilitating the observation of the angle are arranged at the edge of the top end of the chassis 1. Before working, first pass the accessory through between a pair of first limiting plates 7 until it is located between the second limiting plates 8. At this time, the length of the accessory located between the second limiting plates 8 is the length required for bending. The position between the first limiting plates 7 and the second limiting plates 8 is the bending point. When passing through between a pair of first limiting plates 7 and second limiting plates 8, the contact plate 16 will adaptively drive the sliding column 15 to slide inside the fixing cylinder 13 according to the size of the accessory, and squeeze the return spring 14 towards the fixing cylinder 13, realizing the adaptive adjustment of accessories of different sizes and improving the practicability of the device. Then start the servo motor 9 to drive the transmission shaft 10 to rotate. Since the transmission gear 11 at the top end of the transmission shaft 10 meshes with the driven gear 12 on the outside of the central shaft 2, the central shaft 2 and the top plate 3 rotate in opposite directions according to the transmission shaft 10, realizing the bending of the accessory, and the angle to be bent can be flexibly adjusted through the scale lines 20 on the chassis 1. While the top plate 3 is rotating, the slider 18 at the top end of the support rod 19 slides inside the annular groove 17 to disperse the force during bending through the support rod 19, avoiding the fracture at the connection between the top plate 3 and the central shaft 2.
[0021] Working principle: before working, the accessory is first passed through between a pair of first limit plates 7 until it is located between the second limit plates 8. At this time, the length of the accessory located between the second limit plates 8 is the length required for bending, and the first limit plate 7 and the second limit plate 8 are between the bending points. When passing through between the pair of first limit plates 7 and the second limit plates 8, the contact plate 16 will adaptively drive the slide column 15 to slide inside the fixed cylinder 13 according to the size of the accessory, and squeeze the return spring 14 toward the fixed cylinder 13, thereby realizing adaptive adjustment of accessories of different sizes and improving the device. The servo motor 9 is then turned on to drive the transmission shaft 10 to rotate. Because the transmission gear 11 at the top of the transmission shaft 10 and the driven gear 12 on the outside of the center shaft 2 are meshed with each other, the center shaft 2 and the top plate 3 rotate in the opposite direction of the transmission shaft 10, thereby realizing the bending of the accessories, and flexibly adjusting the required bending angle through the scale line 20 on the chassis 1. While the top plate 3 rotates, the slider 18 at the top of the support rod 19 slides in the annular groove 17 to disperse the force during bending through the support rod 19 to avoid breakage at the connection between the top plate 3 and the center shaft 2.
[0022] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
