DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a bending device for hardware products includes a base 1. Support frames 2 are symmetrically welded to the top of the base 1. A bending assembly for changing the mold and bending the hardware products is provided between the support frames 2 close to each other. The bending assembly includes a first motor 31, a rotating disc 32, a rotating rod 33, a connecting plate 34, and a bending mold 35. Mounting plates 8 are welded to the top of the support frames 2. A first motor 31 is installed on one side of one of the mounting plates 8 by screws. Rotating discs 32 are provided on the sides of the mounting plates 8 close to each other. The output end of the first motor 31 penetrates through the mounting plate 8 and is fixedly connected to the middle of the side of one of the rotating discs 32. A rotating rod 33 is welded to the middle of one side of the other rotating disc 32. One end of the rotating rod 33 penetrates through the mounting plate 8 and is connected to a reinforcement assembly for strengthening its position. Both ends of the connecting plate 34 are welded between the sides of the rotating discs 32 close to each other. Bending molds 35 are fixedly connected to the peripheral walls of the connecting plate 34 by screws all around, which can facilitate the disassembly, repair, or replacement of the bending molds 35. Placing grooves 36 are provided at the tops of the bending molds 35 for placing the hardware products to be bent. The bending molds 35 are provided in multiple sizes from small to large for applying to hardware products of different sizes.

[0023] The reinforcement assembly includes a connecting block 41 and a bolt 42. One end of the rotating rod 33 penetrates through the mounting plate 8 and is welded with the connecting block 41. A bolt 42 is rotationally connected to the side of the connecting block 41 away from the mounting plate 8 by threads. A plurality of circumferentially distributed threaded holes 43 are provided on the side of the mounting plate 8 close to the connecting block 41. One end of the bolt 42 extends into the threaded hole 43 and is rotationally connected to the threaded hole 43 by threads.

[0024] During use, start the first motor 31. When the output end of the first motor 31 rotates, the rotating disc 32 connected to it rotates accordingly. When the rotating disc 32 rotates, it drives the other rotating disc 32 to rotate through the connecting plate 34. Thus, the rotation of the connecting plate 34 drives the bending mold 35 to rotate, so that the operator can drive the bending mold 35 to rotate and adjust it to a suitable size for the hardware product by controlling the first motor 31. Then, place the hardware product in the placing groove 36. There is no need for manual removal of the original mold and reinstallation of the mold matching the size of the hardware product during bending, which is convenient for the operator to use and improves the bending efficiency of the bending device for hardware products for the hardware product. At the same time, when the rotating disc 32 rotates, it drives the connecting block 41 to rotate through the rotating rod 33. When the bending mold 35 stops running after rotation adjustment, at this time, rotate the bolt 42 so that one end of it rotates into the threaded hole 43 through the connecting block 41, making the connecting block 41 and the mounting plate 8 stably fixed together, thereby further strengthening the position where the rotating disc 32 is located and enabling the bending mold 35 to perform bending operations stably.

[0025] Inside the placement groove 36, there is an ejection assembly for ejecting and discharging the bent hardware products. The ejection assembly includes an ejection spring 51, a sliding rod 52, and an ejection block 53. Rectangular distribution activity grooves 9 are opened on the inner top surface of the placement groove 36. The inner walls of the activity grooves 9 are welded with ejection springs 51. The other ends of the ejection springs 51 are welded with sliding rods 52. The ends of the sliding rods 52 away from the ejection springs 51 extend out of the activity grooves 9 and are welded to the bottom surface of the ejection block 53. And the sliding rods 52 are all slidably connected to the activity grooves 9. When in use, when an extrusion force is applied to the ejection block 53 to make it move downward, at this time, the sliding rods 52 slide into the activity grooves 9 accordingly. When the sliding rods 52 move downward, the ejection springs 51 are compressed and deformed. When the force applied to the ejection block 53 is released, at this time, the ejection springs 51 return to their original shape, and thus drive the ejection block 53 to move upward and reset through the sliding rods 52, so as to be able to eject and discharge the hardware products placed in the placement groove 36. The structure is simple and the use is convenient.

[0026] Above the ejection block 53, there is a pressing component located at the top of the support frame 2 for pressing and bending the hardware products. The pressing component includes a support plate 61, a second motor 62, a disc 63, a fixing plate 64, and a pressing plate 65. The top of the support frame 2 is welded with the bottom ends of the fixing frames 10 located on both sides of the mounting plate 8. Rectangular grooves 11 are opened on both sides of the inner wall of the fixing frame 10. The two ends of the support plate 61 located above the ejection block 53 are slidably connected to the inside of the rectangular grooves 11. On the side of the support plate 61 close to the ejection block 53, baffles 12 are symmetrically welded. A second motor 62 is installed on one side of one of the baffles 12 by screws. The middle parts of the sides of the baffles 12 close to each other are rotatably connected by a rotating shaft. The output end of the second motor 62 penetrates through the baffle 12 and is fixed to one of the rotating shafts. The ends of a fixing plate 64 are welded between the sides of the discs 63 close to each other. The periphery of the side wall of the fixing plate 64 is fixedly connected by screws with pressing plates 65 matching the bending die 35. The pressing plates 65 and the side walls of the fixing plate 64 are set to be screw-connected, which can facilitate the disassembly, maintenance and replacement of the pressing plates 65.

[0027] When in use, start the second motor 62. When the output end of the second motor 62 rotates, drive the disc 63 to rotate accordingly through the rotating shaft, so that the fixing plate 64 rotates, and then drive the pressing plate 65 to rotate and adjust to be adapted to the bending die 35 through the rotation of the fixing plate 64.

[0028] Both ends of the support plate 61 are connected to a driving component located inside the rectangular groove 11 for driving its movement. The driving component includes a round rod 71, a threaded rod 72, and a third motor 73. The round rod 71 and the threaded rod 72 are respectively arranged inside the rectangular groove 11. One end of the round rod 71 is welded to the bottom surface of the inner wall of the rectangular groove 11, and the other end of the round rod 71 passes through one end of the support plate 61 and is welded to the top surface of the inner wall of the rectangular groove 11. One end of the threaded rod 72 is rotatably connected to the bottom surface of the inner wall of the rectangular groove 11 through a bearing seat. One side of the top of the fixing frame 10 is equipped with a third motor 73. The other end of the threaded rod 72 passes through the support plate 61 and the fixing frame 10 and is fixedly connected to the output end of the third motor 73 through a rotating shaft. The surface of the round rod 71 is slidably connected to the inner wall of the support plate 61, and the surface of the threaded rod 72 is threadedly rotatably connected to the inner walls of both the support plate 61 and the fixing frame 10.

[0029] During use, when the pressing plate 65 is rotated and adjusted to be adapted to the bending die 35, the third motor 73 is started. When the output end of the third motor 73 rotates, it drives the threaded rod 72 to rotate accordingly, so that one end of the support plate 61 slides inside the rectangular groove 11 towards the side close to the bending die 35. When the support plate 61 slides, the other end of it simultaneously slides on the surface of the round rod 71. Furthermore, through the movement of the support plate 61, the baffle 12 drives the pressing plate 65 to move downward through the disc 63 and the fixing plate 64. When the pressing plate 65 continuously moves downward, the hardware products placed in the placement groove 36 can be bent.

[0030] Working principle: When preparing to use the bending device for hardware products, first, according to the size of the hardware products to be bent, the bending component is rotated and operated by controlling the start of the first motor 31. When the bending die 35 is rotated and adjusted to be adapted to the size of the hardware products, the hardware products are placed on the top of the placement groove 36. Then, the second motor 62 is started to control the operation of the pressing component, so that the pressing plate 65 is rotated and adjusted to be adapted to the bending die 35. Subsequently, the third motor 73 is started to make the driving component drive the pressing component to move towards the bending die 35. Under the operation of the third motor 73, the pressing plate 65 can continuously move downward to bend the hardware products. When the pressing plate 65 continuously moves downward to bend the hardware products, the force exerted by the pressing plate 65 on the hardware products causes the ejector block 53 to move downward accordingly, so that the ejector spring 51 is compressed and deformed through the slide bar 52. When the pressing plate 65 moves upward after bending the hardware products, the ejector spring 51 returns to its original shape, and then drives the ejector block 53 to return to its initial state through the slide bar 52. When the ejector block 53 moves upward, the bent hardware products can be ejected from the placement groove 36. The operation is simple, which further improves the practicability of the bending device for hardware products.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
