Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0019] A hardware bending device, as shown in Figures 1-3 and 5, includes a base 1, a placement plate 103, a bracket 2, a hydraulic cylinder 3, a connecting plate 301, a bending plate 4, a push rod 5, a pressure plate 6, and an elastic element 601. The placement plate 103 is slidably connected to the front center of the base 1. The placement plate 103 supports the hardware to be bent and can be adjusted to accommodate workpieces of different thicknesses. Large slots 101 are formed in the middle of the top of both the base 1 and the placement plate 103. Small slots 102 are formed at the bottom inner end of the large slots 101. The small slots 102 facilitate the operator in removing the bent hardware, improving operational convenience. A rectangular slot 104 is formed in the middle of the top of the base 1. A bracket 2 is located at the rear of the top of the base 1. A hydraulic cylinder 3 is built into the upper side of the bracket 2. The hydraulic rod of the hydraulic cylinder 3 is connected to the connecting plate 301. The bottom end of the connecting plate 301 is connected to the bending plate 4, which is located in the rectangular slot 104. Above 04, when the connecting plate 301 drives the bending plate 4 to move downward, the bending plate 4 precisely bends the hardware placed below it. Push rods 5 are connected to both ends of the connecting plate 301. Pressure plates 6 are symmetrically slidably connected to the top of the base 1. Elastic elements 601 are connected between the pressure plates 6 and the base 1. The pressure plates 6 can cover the top of the placement plate 103. The rear side of the pressure plates 6 contacts the push rods 5. During the process of the connecting plate 301 driving the push rods 5 to descend, the parts of the push rods 5 that contact the pressure plates 6 are, in sequence, the lower vertical rod part of the push rods 5, the middle diagonal rod part of the push rods 5, and the upper vertical rod part of the push rods 5. During the process of the lower vertical rod part of the push rods 5 contacting the pressure plates 6, the pressure plates 6 do not move. During the process of the middle diagonal rod part of the push rods 5 contacting the pressure plates 6, the two pressure plates 6 gradually approach each other and cover the top of the hardware. During the process of the upper vertical rod part of the push rods 5 contacting the pressure plates 6, the pressure plates 6 do not move.

[0020] As shown in Figure 5, it also includes a screw 11. The screw 11 is rotatably connected in the large slot 101 of the base 1. The screw 11 is threadedly connected to the placement plate 103. The top of the screw 11 has a slotted opening. By rotating the screw 11, the height of the placement plate 103 can be precisely adjusted to accommodate hardware parts of different thicknesses.

[0021] As shown in Figures 3 and 4, the system also includes a telescopic plate 7, a pull handle 701, a top plate 702, and bolts 8. The telescopic plate 7 is located at the top center of the base 1. The telescopic plate 7 is formed by connecting an inner plate and an outer plate. The top plate 702 is connected to the front end of the telescopic plate 7. The pull handle 701 is connected to the middle of the right end of the top plate 702. The pull handle 701 allows the operator to pull the top plate 702 to move it back and forth along the telescopic plate 7 and adjust it to the required working position. Bolts 8 are threadedly connected to the top of the telescopic plate 7. Bolts 8 abut against the inner plate of the telescopic plate 7.

[0022] As shown in Figures 3 and 4, the base also includes a scale 9 and a measuring pointer 10. The scale 9 is located on the top right side of the base 1, and the measuring pointer 10 is connected to the lower right side of the top plate 702 (the reading of the measuring pointer 10 gradually increases from front to back). The measuring pointer 10 indicates the reading on the scale 9. The scale 9 is used in conjunction with the measuring pointer 10 to help the operator accurately read the position of the top plate 702.

[0023] When preparing to bend the hardware, first adjust the height of the placement plate 103 according to the thickness of the hardware. This is achieved by rotating the screw 11. The top of the screw 11 has a slotted opening to facilitate tool rotation. As the screw 11 rotates, the placement plate 103, which is threaded to it, slides up and down along the base 1 to adjust to a suitable position, ensuring that the pressure plate 6 can stably cover the top of the hardware without causing pressure. Then, adjust the position of the top plate 702 according to the bending length of the hardware, and loosen the bolt 8 so that the bolt 8 no longer abuts against the inner plate of the telescopic plate 7. At this time, the top plate 702 and the inner plate of the telescopic plate 7 can move freely. Pull the top plate 702 with the handle 701 to extend or shorten the telescopic plate 7. With the help of the measuring pointer 10 and the scale 9, make the scale indicated by the measuring pointer 10 consistent with the required bending length of the hardware to determine the position of the top plate 702. Then tighten the bolt 8 to fix the position of the top plate 702 by fixing the telescopic plate 7. Finally, place the hardware on the placement plate 103 so that... The rear end of the hardware part abuts against the top plate 702. At this time, the part of the hardware part to be bent is suspended above the rectangular groove 104. The hydraulic cylinder 3 is activated, and the hydraulic cylinder 3 pushes the connecting plate 301 and the bending plate 4 downward. The bending plate 4 contacts the hardware part to achieve bending and forming. During the downward movement of the connecting plate 301, the push rods 5 on both sides move synchronously, pushing the pressure plates 6 on the left and right sides closer to each other. During this process, the elastic element 601 changes from the initial state to the stretched state. Before the bending plate 4 contacts the hardware part, the pressure... Plate 6 will smoothly cover the upper surface of the hardware, effectively fixing the hardware and preventing the hardware from changing position during bending. After the bending of the hardware is completed, the hydraulic cylinder 3 resets and drives the bending plate 4 and push rod 5 to rise. The elastic element 601 resets, so that the pressure plate 6 automatically returns to its original position and disengages from the hardware. Finally, the operator can reach into the small slot 102 to take out the formed hardware. Place the next piece of hardware that needs to be bent on the placement plate 103 and repeat the above operation to process the hardware.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
