[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See Figures 1 to 4 As shown, the bending device for hardware accessories processing provided by the present invention includes a base 1, a hardware accessory 2 is provided on the top of the base 1, the front of the hardware accessory 2 is fitted with a limit plate 8, the bottom end of the limit plate 8 is fixedly connected to the base 1, two groups of movable grooves are opened inside the base 1 at the bottom end of one side of the hardware accessory 2, and the bottom end of the pushing mechanism is slidably sleeved inside the movable groove, a cavity is opened inside the base 1, and the adjustment mechanism is movably sleeved inside the cavity, and the side of the adjustment mechanism is fitted to the other side of the hardware accessory 2.

[0024] First, one end of the hardware accessory 2 is fitted with the surface of the limiting plate 8 and placed on the top of the base 1. The position of each group of forming plates 5 is adjusted by the adjustment mechanism, and the curvature diameter of the forming plate is adjusted to adapt to different processing requirements. Then, the pushing mechanism is started to fit the surface of the roller 18 with the surface of the hardware accessory 2, and pressure is applied to the hardware accessory 2 to fit the forming plate 5 and shape it, thereby adapting to forming plates 5 of various shapes.

[0025] The adjustment mechanism includes a motor 2 6, the top of which is fixedly connected to the bottom of the base 1, and the output end of the motor 2 6 is fixedly connected to a gear 1 9, the outer wall of the gear 1 9 is meshed with the outer wall of the gear 2 10, and six groups of limiting slides 11 are provided inside the gear 2 10. The six groups of limiting slides 11 are arranged in a circular array with the limiting column 7 as the center of the circle, and the six groups of limiting slides 11 are movably sleeved with a connecting rod 12 inside, and the top of the connecting rod 12 is fixedly connected to a connecting slider 22, and the outer side of the top of the connecting slider 22 is fixedly connected to a group of forming plates 5.

[0026] The inner movably sleeve of the gear 2 10 is connected to the limiting column 7 , and the bottom end of the limiting column 7 is fixedly connected to the base 1 .

[0027] By starting motor 2 6, the output end of motor 2 6 drives gear 1 9 to rotate inside the base 1 and engage with gear 2 10. The rotating gear 2 10 drives connecting rod 12 to slide inside. When the connecting rod 12 is adjusted to the position, the connecting rod 12 pulls the top connecting slider 22 to slide inside the base 1, thereby driving each group of forming plates 5 to adjust its distance from the center of the circle. When the connecting rod 12 slides toward the center, the forming plate 5 moves inward synchronously, so that the curved surface of the forming plate 5 on the fitting surface of the hardware accessory 2 is changed, thereby adapting to more work tasks and reducing the need to replace molds.

[0028] The pushing mechanism includes a movable connecting plate 3, a sliding groove is opened inside the movable connecting plate 3, and a connecting rod 2 13 is fixedly connected to the inside of the sliding groove. The outer wall of the connecting rod 2 13 is movably sleeved with two groups of sleeve blocks 2 19. The outer wall of the sleeve block 2 19 is fixedly connected to one end of the push plate 17, and the other end of the push plate 17 is hinged with a roller 18.

[0029] One end of the transmission rod 16 is hinged to the outer wall of the push plate 17 , the other end of the transmission rod 16 is hinged to the sleeve block 15 , and the inner wall of the sleeve block 15 is slidably sleeved with the connecting rod 2 13 .

[0030] The outer wall of the connecting rod 2 13 is movably connected to two sets of blocks 15 and two sets of blocks 2 19, and the two sets of blocks 15 and the two sets of blocks 2 19 are centrally symmetrical. The outer wall of the connecting rod 2 13 is movably connected to the spring 14, and the spring 14 is evenly distributed at both ends of the two sets of blocks 15 and the two sets of blocks 2 19.

[0031] The bottom end of the movable connecting plate 3 is fixedly connected with two groups of sleeve blocks 3 23, wherein the internal movably sleeved sleeve of one group of sleeve blocks 3 23 is a sleeve rod 21, and the two ends of the sleeve rod 21 are fixedly connected to the inner wall of the base 1; the internal thread of the other group of sleeve blocks 3 23 is connected with a threaded rod 20, and one end of the threaded rod 20 is fixedly connected to the output end of the motor 1 4, and the outer wall of the motor 1 4 is fixedly connected to the side of the base 1.

[0032] By starting motor 1 4, the output end of motor 1 4 drives the threaded rod 20 to rotate inside the base 1, thereby adjusting the distance between the sleeve block 3 23 and the base 1, so that the top movable connecting plate 3 is close to the hardware accessory 2. When the movable connecting plate 3 moves toward the hardware accessory 2, the roller 18 first fits the surface of the hardware accessory 2, and the push plate 17 under pressure drives the sleeve block 2 19 to slide on the surface of the connecting rod 2 13, so that the push plate 17 moves toward the two ends of the movable connecting plate 3, and applies thrust to the hardware accessory 2 through the roller 18, so that the surface of the hardware accessory 2 fits the outer wall of the forming plate 5, thereby completing the shaping of the hardware accessory 2. At the same time, the sleeve block 15 moves synchronously to the two ends, and the push plate 17 is supported by the transmission rod 16 to keep the push plate 17 stable when moving. When the pushing is completed, the two sets of sleeve blocks 1 15 and the two sets of sleeve blocks 2 19 are pushed back to their original positions under the influence of the elastic potential energy of the spring 14, thereby facilitating the next bending.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
