When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] Please see Figures 1 to 8 The shield bending machine according to one embodiment of the present utility model includes a carrying component 10, a bending component 20 installed on the top surface of the carrying component 10, a loading and unloading component 30 installed on the top surface of the carrying component 10, and a conveying component 40 located on one side of the carrying component 10; the conveying component 40 is used to convey a fixture 51, and the top of the fixture 51 correspondingly carries the shield 52 to be bent.

[0035] The support assembly 10 includes a frame 11 and a processing table 12 mounted on the center of the top surface of the frame 11. The interior of the processing table 12 is used to accommodate a fixture 51.

[0036] like Figure 2 and Figure 3 As shown, the machining table 12 has first through holes 13 on its opposite sides, and a second through hole 14 is provided above each of the first through holes 13 on the machining table 12. The opening direction of the first through holes 13 is inclined to the bottom surface of the machining table 12, and the opening direction of the second through holes 14 is parallel to the bottom surface of the machining table 12.

[0037] Furthermore, the top surface of the frame 11 is provided with through slots 15 on opposite sides of the processing table 12, and the through slots 15 correspond one-to-one with the first through holes 13.

[0038] The bending assembly 20 includes a support frame 21 covering the processing table 12, a retractable pressing block 22 connected to the middle of the support frame 21, two retractable positioning posts 23 installed inside the frame 11, and bending posts 24 retractably connected to the inner walls of opposite sides of the support frame 21; the bending posts 24 correspond one-to-one with the positioning posts 23. The positioning posts 23 are used to pass through the frame 11 and the processing table 12 and abut against the fixture 51 to clamp the fixture 51; the bending posts 24 are used to pass through the processing table 12 and abut against and bend the support legs 53 of the shielding cover 52.

[0039] Specifically, the positioning post 23 is provided with a through groove 15 and a first through hole 13, and the bent post 24 is provided with a second through hole 14.

[0040] In this embodiment, the pressing block 22 is connected to the support frame 21 through the pressing cylinder 220. The pressing cylinder 220 drives the pressing block 22 to abut against the shielding cover 52, thereby achieving vertical positioning of the shielding cover 52.

[0041] In this embodiment, the positioning column 23 is connected to the frame 11 through the positioning cylinder 230. The positioning cylinder 230 drives the positioning column 23 to abut against the fixture 51, thereby achieving horizontal positioning of the fixture 51, which is also horizontal positioning of the shielding cover 52.

[0042] In this embodiment, the bending column 24 is connected to the frame 11 via the bending cylinder 240, and the bending cylinder 240 drives the bending column 24 to abut against and bend the support leg 53.

[0043] The loading and unloading assembly 30 includes two baffles 31 that can be lifted and installed inside the support frame 21, a slide cylinder 32 connected to the support frame 21, a first push block 33 connected to one end of the slide cylinder 32, a second push block 34 connected to the other end of the slide cylinder 32, and a distance sensor 35 installed inside the second push block 34; the first push block 33 and the second push block 34 are located between the two baffles 31. The space between the first push block 33 and the second push block 34 is used to accommodate the fixture 51, and the distance sensor 35 is used to detect whether the fixture 51 is in position. The slide cylinder 32 drives the first push block 33 and the second push block 34 to move, thereby driving the fixture 51 to move into or out of the processing table 12. Simply put, by controlling the displacement of the slide cylinder 32, the support leg 53 can be directly aligned with the bending column 24, and the shielding cover 52 at different support leg positions can enter the processing table 12 for bending.

[0044] like Figure 5 As shown, in this embodiment, the baffle 31 is connected to the support frame 21 via the blocking cylinder 310.

[0045] In this embodiment, the movement direction of the slide cylinder 32 is perpendicular to the length direction of the bending column 24.

[0046] like Figure 6 As shown, the first push block 33 is connected upward to one end of the slide cylinder 32 via the first adapter plate 330, and the second push block 34 is connected upward to the other end of the slide cylinder 32 via the second adapter plate 340.

[0047] Furthermore, in order to improve the stability of the first push block 33 and the second push block 34, a reinforcing plate 36 is also connected between the first adapter plate 330 and the second adapter plate 340.

[0048] The conveying assembly 40 includes a conveyor belt 41 installed on one side of the processing table 12 and a photoelectric sensor 42 installed on the side of the conveyor belt 41 away from the processing table 12. The conveying direction of the conveyor belt 41 is perpendicular to the movement direction of the slide cylinder 32. The conveyor belt 41 is used to convey the fixture 51 and the shielding cover 52, and the photoelectric sensor 42 is used to detect whether the fixture 51 and the shielding cover 52 are in place.

[0049] In actual operation, the slide cylinder 32 drives the first push block 33 and the second push block 34 to move onto the conveyor belt 41, which is responsible for conveying the fixture 51 and the shielding cover 52. When the photoelectric sensor 42 detects that the fixture 51 and the shielding cover 52 have passed, the two baffles 31 fall down, precisely intercepting one fixture 51 and the shielding cover 52 between the first push block 33 and the second push block 34. At this time, the conveyor belt 41 stops running. Next, the slide cylinder 32 drives the first push block 33 and the second push block 34 to move into the interior of the processing table 12, so that the support leg 53 corresponds to the bending column 24. Then, the lower pressure block 22 and the positioning column 23 extend simultaneously to fix the shielding cover 52, and then the bending column 24 extends to bend the support leg 53. After bending is completed, the lower pressure block 22, the positioning column 23, and the bending column 24 retract respectively. The slide cylinder 32 drives the first pusher block 33 and the second pusher block 34 to move onto the conveyor belt 41. The two baffles 31 rise, and the conveyor belt 41 restarts. The bent shielding cover 52 is transported to the next process along with the conveyor belt 41, while the shielding cover 52 to be bent re-enters between the first pusher block 33 and the second pusher block 34, ready for the next round of bending. The above process is repeated cyclically to achieve continuous and orderly bending processing of the shielding cover 52.

[0050] The aforementioned shielding cover bending machine has a simple structure and is easy to use. By using the slide cylinder 32 to drive the first push block 33 and the second push block 34 to move, the support leg 53 can be directly aligned with the bending column 24. It can adapt to different support leg position requirements without frequent mold changes, reducing the complexity of operation and effectively controlling production costs.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
