Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to a bending machine for processing spare parts. Background Technology

[0002] A bending machine is a specialized device for bending parts. Its applications are wide-ranging, covering multiple industries such as machinery, electrical appliances, and hardware, and penetrating almost all manufacturing sectors, from large transportation vehicles like airplanes and ships to small household appliances, electrical boxes, and various spare parts. However, most bending machines on the market today share a common problem: a lack of effective fixing devices. This deficiency causes parts, once placed on the bending machine's worktable, to easily shift at an angle due to external forces, making it impossible to achieve an ideal parallel placement. Once a part shifts at an angle during the bending process, the result is often an inaccurate bending angle. Such parts often have to be discarded, directly increasing production costs and severely reducing overall production efficiency.

[0003] For example, Chinese patent CN222020432U discloses a bending machine for precision parts processing, belonging to the field of bending machine technology. It includes a worktable, a protective cover fixedly connected to the top surface of the worktable, a rectangular block fixedly installed on one side of the top surface of the worktable, a connecting column fixedly connected to one side of the rectangular block, the free end of the connecting column fixedly connected to one side inner wall of the protective cover, a slider sleeved around the periphery of the connecting column, a movable block fixedly connected to one side of the slider, a bevel machined on the bottom surface of the movable block's inner cavity away from the slider, and multiple first bolts threadedly connected to the top surface of the movable block. The bottom end of each first bolt penetrates the movable block and is fixedly connected to a circular pressure plate. A scale is provided on the top surface of the worktable, and a threaded hole is opened on the top surface of the slider, with a second bolt threadedly connected to the inner cavity of the threaded hole. This bending machine for precision parts processing solves the problem of angular displacement of parts after placement in the bending machine, improving the efficiency of precision parts production.

[0004] Although the above-mentioned device can fix and clamp the parts with a circular pressure plate and bend the parts by pressing down with a bending plate, the process of using the device is cumbersome and reduces the processing efficiency of the parts to a certain extent.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] Please refer to Figures 1 to 6 As shown, a bending machine for processing spare parts includes an operating table 1. Two sets of guide frames 2 are fixedly installed on the top of the operating table 1. A workpiece 3 to be processed is slidably connected inside the two sets of guide frames 2. A bending mechanism 4 is provided on the outer periphery of the workpiece 3 and at the top of the operating table 1. The bending mechanism 4 includes a drive motor 401 fixedly installed at the bottom of the operating table 1. The output end of the drive motor 401 extends above the operating table 1 and is fixedly connected to a rotating plate 402. A connecting column 403 is fixedly connected to the top of one side of the rotating plate 402. A second rotating plate 404 is fixedly connected to the top of the connecting column 403 and above the rotating plate 402. A first rotating rod 405 is rotatably connected to the top of the other side of the rotating plate 402. The output end of the first rotating rod 405 extends above the second rotating plate 404. A gear 406 is fixedly connected to the top of the gear 406. A semi-guide roller 407 is fixedly connected to the top of the rotating plate 404. A rotating rod 408 is rotatably connected to the top of the rotating plate 404 via a bearing. A full guide roller 409 is fixedly connected to the end of the rotating rod 408 away from the rotating plate 404. A guide plate 410 is fixedly connected to the outer surface of the rotating plate 402. A cylinder 411 and a sliding rail 412 are fixedly installed on the top of the operating table 1. A toothed plate 413 is fixedly connected to the output end of the cylinder 411. The toothed plate 413 slides inside the sliding rail 412 and meshes with the gear 406. A vertical plate frame 5 is fixedly connected to the top of the operating table 1. A lifting mechanism 6 is provided inside the vertical plate frame 5. A lifting frame 7 is fixedly connected to the outer surface of the lifting mechanism 6. A clamping mechanism 8 is provided inside the lifting frame 7.

[0032] In this scheme, the workpiece 3 to be processed is first guided through the reserved space between the two sets of guide frames 2 and the semi-guide roller 407 and the full guide roller 409 (e.g., Figure 3As shown), and the required bending length is reserved. Then, drive motor 401 is turned on. Drive motor 401 drives rotating plate 402 to rotate, which in turn drives rotating plate 404 to rotate through connecting column 403. Since rotating rod 405 is rotatably connected to rotating plate 402 and rotating plate 404, when rotating plate 402, connecting column 403 and rotating plate 404 rotate, gear 406 and semi-guide roller 407 do not rotate. Therefore, when rotating plate 402, connecting column 403 and rotating plate 404 rotate, they drive full guide roller 409 and guide bending plate 410 to rotate, thereby allowing the semi-guide roller 407 and full guide roller 409 to rotate. The workpiece 3, which is reserved on the outside of the roller 409, is bent. After the workpiece 3 is bent, the full guide roller 409 and the guide plate 410 are reset. Then the cylinder 411 is activated. The cylinder 411 drives the toothed plate 413 to move inside the sliding rail 412. In turn, the toothed plate 413 drives the gear 406 to rotate. The gear 406 drives the half guide roller 407 to rotate. When the half guide roller 407 rotates to the designated position and can no longer form a guiding function with the full guide roller 409, the workpiece 3 can be taken out from the bending mechanism 4 after processing through the lifting mechanism 6 and the clamping mechanism 8, thus optimizing the bending steps of the workpiece 3.

[0033] The lifting mechanism 6 includes a lead screw 601 rotatably connected inside the upright frame 5. Two sets of fixing rods 602 are also fixedly connected inside the upright frame 5, symmetrically distributed on opposite sides of the lead screw 601. A second drive motor 603 is fixedly installed on the top of the upright frame 5. The output end of the second drive motor 603 extends into the interior of the upright frame 5 and is fixedly connected to one end of the lead screw 601. A movable block 604 is threaded onto the outer circumferential surface of the lead screw 601. The movable block 604 is slidably connected to both sets of fixing rods 602. The outer side of the movable block 604 is fixedly connected to the lifting frame 7. The clamping mechanism 8 includes a double-ended lead screw 801 rotatably connected inside the lifting frame 7. Two sets of fixed rods 802 are also fixedly connected inside the lifting frame 7. The two sets of fixed rods 802 are symmetrically distributed on opposite sides of the double-ended lead screw 801. A drive motor 803 is fixedly installed on the right side of the lifting frame 7. The output end of the drive motor 803 extends into the interior of the lifting frame 7 and is fixedly connected to one end of the double-ended lead screw 801. Moving blocks 804 are threadedly connected to opposite sides of the outer circumference of the double-ended lead screw 801. Clamping plates 805 are fixedly connected to the bottom of each moving block 804.

[0034] After the workpiece 3 is bent, drive motor 2 603 is turned on. Drive motor 2 603 drives lead screw 601 to rotate, and then the movable block 604 is lowered by the guidance of two sets of fixed rods 1 602, so that the lifting frame 7 is lowered. When the lifting frame 7 is lowered to the appropriate position, drive motor 3 803 is turned on. Drive motor 3 803 drives double-headed lead screw 801 to rotate, and then the two moving blocks 804 on both sides are brought closer to each other by the guidance of two sets of fixed rods 2 802, so that the clamping plates 805 on both sides can effectively clamp the bent workpiece 3, and then the workpiece 3 can be taken out by drive motor 2 603.

[0035] The working principle and usage procedure of this device are as follows: First, the workpiece 3 to be processed is guided through the reserved space between the two sets of guide frames 2 and the semi-guide roller 407 and the full guide roller 409 (e.g., Figure 3 As shown), the length to be bent is reserved. Then, drive motor 401 is turned on, which drives rotating plate 402 to rotate. In turn, rotating plate 404 is driven to rotate through connecting column 403. Since rotating rod 405 is rotatably connected to rotating plate 402 and rotating plate 404, when rotating plate 402, connecting column 403 and rotating plate 404 rotate, gear 406 and semi-guide roller 407 do not rotate. When rotating plate 402, connecting column 403 and rotating plate 404 rotate, they drive full guide roller 409 and guide bending plate 410 to rotate. This allows bending of the workpiece 3 reserved on the outside of semi-guide roller 407 and full guide roller 409. After the workpiece 3 is bent, full guide roller 409 and guide bending plate 410 are reset. Then, cylinder 411 is turned on, which drives the gear plate. 413 moves inside the sliding rail 412, thereby driving the gear 406 to rotate via the toothed plate 413. The gear 406 then drives the semi-guide roller 407 to rotate. When the semi-guide roller 407 rotates to the designated position and cannot form a guiding effect with the full guide roller 409, the second drive motor 603 is turned on. The second drive motor 603 drives the lead screw 601 to rotate, thereby guiding the movable block 604 to descend through the two sets of fixed rods 602, causing the lifting frame 7 to descend. When the lifting frame 7 descends to the appropriate position, the third drive motor 803 is turned on, driving the double-headed lead screw 801 to rotate, thereby guiding the two moving blocks 804 on both sides to move closer to each other through the two sets of fixed rods 802, so that the clamping plates 805 on both sides can effectively clamp the bent workpiece 3, and the workpiece 3 can be taken out by the second drive motor 603.
