Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This specific embodiment is a bending device for metal manufacturing, and its structural schematic diagram is shown below. Figures 1 to 5 As shown, the device includes a base 1, a support frame 2 fixedly connected to the upper end of the base 1, a hydraulic cylinder 3 installed at the middle position of the upper side of the support frame 2, a mounting plate 4 fixedly connected to the lower end of the output shaft of the hydraulic cylinder 3, a bending mechanism provided at the upper end of the base 1, the bending mechanism including a fixed shaft 501 fixedly connected to the middle position of the lower side of the mounting plate 4, a lower pressure block 502 provided at the lower end of the fixed shaft 501, a connecting ring 503 fixedly connected at the middle position of the upper side of the lower pressure block 502, a bolt 504 connected to the lower end of the interior of the fixed shaft 501, a third threaded hole extending through the left and right sides opened at the lower end of the fixed shaft 501, round holes opened at both ends of the connecting ring 503, the outer side of the bolt 504 slidably connected to the inner side of the round hole, the outer side of the bolt 504 threadedly connected to the inner side of the third threaded hole, and the outer side of the lower end of the fixed shaft 501 slidably connected to the inner side of the connecting ring 503. After sliding the connecting ring 503 to the outer side of the lower end of the fixed shaft 501, the bolt 504 is passed through the round hole and threaded into the third threaded hole, so that the connecting ring 503 is fixed to the outer side of the lower end of the fixed shaft 501, completing the installation of the lower pressure block 502. Then, different lower pressure blocks 502 can be disassembled and assembled through this disassembly and assembly method, so that different lower pressure blocks 502 can be replaced for bending when bending different metal parts.

[0030] The base 1 has sliding frames 505 connected to its left and right ends. Fixed plates 506 are fixedly connected to the front and rear ends of the upper side of the sliding frames 505. A round shaft 507 is fixedly connected to one side of each of the two fixed plates 506. A support roller 508 is rotatably connected to the outer side of the round shaft 507. A first threaded rod 509 is connected to the lower front end of the sliding frame 505. A first handle 510 is welded to the front end of the first threaded rod 509. Limiting rods 511 are fixedly connected to the upper ends of the front and rear sides of the base 1. The inner side of the sliding frame 505 is slidably connected to the outer side of the upper end of the base 1. Sliding grooves are formed at the front and rear ends of the inner side of the sliding frame 505. The outer side of the limiting rod 511 is slidably connected to the inner side of the sliding grooves. The front and rear sides of the support roller 508 are slidably connected to one side of each of the two fixed plates 506. The outer side of the support roller 508 abuts against the left and right ends of the lower side of the metal part to be bent. A groove is formed inside the base 1. A second threaded hole is provided below the front end of the sliding frame 505. The outer side of the first threaded rod 509 is threaded to the inner side of the second threaded hole, and the rear end of the first threaded rod 509 abuts against the front side of the base 1. By sliding the sliding frame 505 along the outer side of the upper end of the base 1, and then threading the first threaded rod 509 into the second threaded hole until the rear end of the first threaded rod 509 abuts against the front side of the base 1, the sliding frame 505 can be fixed to the upper end of the base 1. Thus, according to the different bending positions of different metal parts, the position of the sliding frame 505 can be adjusted to move the support roller 508 to the left and right ends below the bending position of the metal part, so that the bending device can meet the bending requirements of different metal parts.

[0031] Cooperate Figure 6The lower end of the mounting plate 4 is provided with a positioning mechanism, which includes a bearing 601 connected inside the mounting plate 4. A second threaded rod 602 is fixedly connected to the inner side of the bearing 601. A third handle 603 is welded to the end of the second threaded rod 602 away from the bearing 601. An adjusting block 604 is connected to the outer end of the second threaded rod 602. An L-shaped plate 605 is fixedly connected to the lower side of the adjusting block 604. The left and right ends of the mounting plate 4 are symmetrically provided with through slots. The bearing 601 is installed on the side of the through slot near the center of the mounting plate 4. A first threaded hole is provided in the middle position inside the adjusting block 604. The front and rear sides of the adjusting block 604 are slidably connected to the front and rear ends of the through slot. The outer side of the second threaded rod 602 is threadedly connected to the inner side of the first threaded hole. The L-shaped plates 605 at the lower left and right ends of the mounting plate 4 are symmetrical. The left and right sides of the metal part to be bent are slidably connected to the side adjacent to the vertical part of the two L-shaped plates 605, and the lower sides of the left and right ends of the metal part are slidably connected to the upper side of the horizontal part of the L-shaped plates 605. Thus, when the second threaded rod 602 is rotated by rotating the third handle 603, the adjusting block 604 moves along the inner side of the through groove, which in turn moves the lower L-shaped plates 605, changing the position of the two L-shaped plates 605 at the lower left and right ends of the mounting plate 4. This allows the two L-shaped plates 605 at the left and right ends to be adjusted in advance to the position of the left and right ends of the metal part to be bent according to the required length and bending position. This ensures that when the metal part is slid between the two L-shaped plates 605 during subsequent installation, the bending position will be accurately located below the lower pressing block 502, improving the installation speed of the metal part during bending and thus increasing the efficiency of the bending work.

[0032] Working principle: When bending a metal part, first rotate the third handle 603 at both ends of the mounting plate 4, which drives the second threaded rod 602 to rotate, causing the adjusting block 604 and the L-shaped plate 605 to move until the L-shaped plates 605 at both ends move to the positions of the left and right ends of the metal part when it is bent. Then, slide the sliding frame 505 along the upper end of the base 1 until it drives the support rollers 508 at both ends to move to the positions of the left and right ends below the part to be bent. Then, thread the first threaded rod 509 to the second threaded hole and the front end of the base 1. The sliding frame 505 is fixed in place, and then the metal part to be bent is slid between the L-shaped plates 605. Then the hydraulic cylinder 3 is activated, and its output shaft moves down, causing the mounting plate 4 and the lower pressure block 502 to move down together. During the downward movement, the metal part will first contact the support roller 508, and then be supported by the support roller 508, gradually moving away from the lower end of the L-shaped plate 605. Then it will be bent by the L-shaped plate 605, which continues to move down. When the metal part is bent to the required curvature, the lower pressure block 502 is lifted again, and the bent metal part is removed from the support roller 508.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
