Technical Field

[0001] The utility model relates to the field of metal plate processing, in particular to a bending device. Background Art

[0002] At present, most of the four sides of the back panel of modern popular LCD TVs are F-shaped folded edges. The prior art discloses a thick plate bending forming mold with application number 202021344483.4, including an upper mold and a lower mold, the upper mold including an upper mold base, an upper pad and an upper mold plate arranged in sequence from top to bottom, and a bending punch and an insert block are provided at the bottom of the upper mold plate; the lower mold includes a lower mold base, a lower mold plate, a lower pad and a stripping plate arranged in sequence from bottom to top, a first reset spring is connected between the stripping plate and the lower pad, a bending forming block is provided on one side of the lower pad, the bending forming block is slidably arranged on the top of the lower mold plate, the bending punch includes a first bending plane, the bending forming block includes a second bending plane, a driving inclined surface is provided on the side of the insert block facing the bending punch, and a driven inclined surface is provided on the side of the bending forming block facing away from the lower pad, a fixed block is provided on the top of the lower mold plate, and a second reset spring is connected between the bending forming block and the fixed block. When in use, place the product on the stripping plate and the bending forming block, and then start the upper die to move downward. The product is first pressed by the bending punch and the stripping plate, and then the upper die continues to move downward, thereby driving the stripping plate to move downward together and bend the product. At this time, the first return spring is compressed; at the same time, the insert block will push the bending forming block to slide toward the lower pad through the cooperation of the driving inclined surface and the driven inclined surface, so that the second bending plane on the bending forming block and the first bending plane on the bending punch cooperate, thereby bending the product to 89°, and the second return spring is stretched at this time; when the upper die and the lower die are opened, the formed workpiece will rebound from 89° to 90° to meet the processing requirements.

[0003] However, the above-mentioned thick plate bending forming mold has these problems. The upper end of the product is pressed by the bending punch, and the lower end is pressed by the stripping plate. Because the length and width of the product are large and not unique, the bending punch cannot completely cover the upper end surface of the product. Therefore, during the bending process of the product, the product is very likely to crack due to uneven force, resulting in product scrapping. If the upper end of the product does not need to be pressed by the bending punch, the product will easily fall off the stripping plate during the bending process, and production efficiency will be greatly reduced.

[0024] The bending device of the utility model has a simple structure and is easy to use. Compared with the prior art, the bending device eliminates the use of a bending punch to press the upper end of the workpiece 6, which can avoid uneven force on the workpiece 6. The connecting part 12 can be used to install different workpieces 6. When in use, the driving component drives the movable template 1 to move along the upper end surface of the fixed template 2 toward the bending and forming part 5, and the bending and forming part 5 bends the workpiece 6 installed on the connecting part 12. The operation is simple. At the same time, the slider 21 is clamped in the slide groove 11 and is slidably connected to the slide groove 11, so that the movable template 1 is not easy to separate from the fixed template 2 during the movement process and the bending process of the workpiece 6, thereby improving production efficiency and having strong stability.

[0025] In this embodiment, the bending and forming part 5 is connected to an external device, so that the corresponding type of bending and forming part 5 can be selected according to the type of bending of the workpiece 6, and the application range is wide. One end of the workpiece 6 is detachably connected to the connecting part 12, and the other end of the workpiece 6 extends to the bending and forming part 5 to form a component 61 that needs to be bent by the bending and forming part 5. The bending and forming part 5 bends the component 61, and the operation is simple. Specifically, the workpiece 6 is threadedly connected to the connecting part 12, and the connection is stable.

[0026] Furthermore, the slide groove 11 penetrates the lower end surface of the movable template 1, that is, the two ends of the slide groove 11 penetrate the two side surfaces of the movable template 1, which is convenient for replacing different movable templates 1 as needed. Specifically, the slider 21 can enter the slide groove 11 through the notch of the slide groove 11 located on one side of the movable template 1, which is convenient for assembly. In this embodiment, the distance between the outer wall of the slider 21 and the groove wall of the slide groove 11 is 0.05-1mm, which is convenient for inserting the slider 21 into the slide groove 11. In this embodiment, the slide groove 11 penetrates the lower end surface of the movable template 1 and the connecting portion 12 in sequence.

[0027] Further, the slide groove 11 includes a first groove 111 and a second groove 112 connected to the first groove 111, and the second groove 112 and the first groove 111 are respectively opened in the lower end surface of the movable template 1 from bottom to top; the slider 21 includes a first clamping portion 211 and a second clamping portion 212, the first clamping portion 211 is clamped in the first groove 111 and is slidably connected to the first groove 111, the lower end of the second clamping portion 212 is fixedly connected to the fixed template 2, the upper end of the second clamping portion 212 passes through the second groove 112 and is fixedly connected to the first clamping portion 211, and the second clamping portion 212 is slidably connected to the second groove 112, and the structure is simple.

[0030] Further, the lower end of the insert block 3 is inserted into the fixed template 2 and is slidably connected to the inner wall of the fixed template 2. The side of the insert block 3 facing the movable template 1 is provided with a driving inclined surface 31, and the side of the movable template 1 facing the insert block 3 is provided with a driven inclined surface 13 corresponding to the driving inclined surface 31. The driving member is used to drive the insert block 3 to slide up and down relative to the fixed template 2 to drive the driving inclined surface 31 of the insert block 3 to slide along the driven inclined surface 13 of the movable template 1, that is, the insert block 3 pushes the movable template 1 to slide along the upper end surface of the fixed template 2 toward the bending forming portion 5 through the cooperation of the driving inclined surface 31 and the driven inclined surface 13, so that the workpiece 6 installed on the connecting portion 12 is bent through the bending forming portion 5. In this way, the occupied area of ​​the insert block 3 can be reduced, and at the same time, by changing the angle between the driving inclined surface 31 and the axis of the insert block 3, and the angle between the driven inclined surface 13 and the movable template 1, the sliding distance of the movable template 1 along the fixed template 2 can be adjusted, and the bending angle and length of the workpiece 6 can be changed, and the use range is wide.

[0032] Furthermore, a limit block 4 is provided at the upper end of the fixed template 2, and the limit block 4 abuts against the end of the plug block 3 away from the movable template 1. The limit block 4 is used to limit the position of the plug block 3, so that the plug block 3 is not easily displaced during the movement along the inner wall of the fixed template 2, and the operation is stable.

[0033] Further, the bending forming portion 5 includes a guide portion 51 and a bending portion 52, one end of the guide portion 51 is connected to the bending portion 52, the other end of the guide portion 51 extends toward the connecting portion 12, the upper end surface of the guide portion 51 is used for placing a component 61 of the workpiece 6 protruding from the connecting portion 12 to the bending portion 52, and the bending portion 52 is used to bend the component 61 of the workpiece 6 protruding from the connecting portion 12 to the bending portion 52. In this embodiment, one end of the workpiece 6 is detachably connected to the connecting portion 12, and the other end of the workpiece 6 extends along the upper end surface of the guide portion 51 to form a component 61 that needs to be bent by the bending portion 52, and the bending portion 52 bends the component 61, which is easy to operate. Specifically, the movable template 1 moves along the upper end surface of the fixed template 2 toward the bending and forming part 5, driving the workpiece 6 installed on the connecting part 12 to move toward the bending and forming part 5. When the part 61 of the workpiece 6 protruding outward from the connecting part 12 slides along the upper end surface of the guide part 51 until it is stamped onto the bending part 52, the part 61 is compressed and deformed along the shape of the bending part 52, thereby achieving a bending effect.
