[0034] The present invention will be described in detail below with reference to specific embodiments.

[0035] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figures 1 to 8 As shown, a planar high-speed bending forming machine includes a frame 10, a feeding device 11, a wire adjusting device 20, a wire feeding device 30, a bending device 40, and a cutting device 50. This design results in a compact overall structure, reducing the machine's size by two-thirds compared to traditional forming machines. The small size not only saves significant floor space but also facilitates equipment layout and movement, improving the space utilization of the production site.

[0038] The frame 10 is equipped with a feeding device 11, a wire adjusting device 20, a wire feeding device 30, a bending device 40, and a cutting device 50 sequentially along its length. The feeding device 11 is a disc structure with multiple sets of guide rollers surrounding it. The wire passes through these guide rollers for straightening and stabilizing the wire, effectively reducing wobbling and deviation when the wire enters the straightening device. This ensures the wire enters the straightening device smoothly, providing straight wire that meets the straightness standards for subsequent processes, resulting in better straightening performance.

[0039] The bending device 40 includes a bending turntable 41 and a turntable drive mechanism. The bending turntable 41 is rotatably mounted on the platform plate 12 of the frame 10. The bending turntable 41 is provided with a bending column 42 driven by a cylinder. The turntable drive mechanism is used to drive the bending turntable 41 to rotate axially, thereby causing the bending column 42 to rotate with the bending turntable 41, and bending the passing wire at different angles.

[0040] The cutting device 50 includes a cutting upper die 51 protruding and fixed at the center of the bending turntable 41, a telescopic rod 52 slidingly passing through the axial center of the bending turntable 41, and a telescopic rod drive mechanism for driving the telescopic rod 52 to move up and down. A cutting blade 53 located inside the cutting upper die 51 passes through the upper end of the telescopic rod 52. A wire-passing hole 511 passes through the interior of the cutting upper die 51. The wire passes through the wire-passing hole 511, and the bending column 42 rotates with the bending turntable 41, bending the wire moving out of the cutting upper die 51 at different angles. The telescopic rod drive mechanism drives the cutting blade 53 at the upper end of the telescopic rod 52 to cut the wire in conjunction with the wire-passing hole 511 in the cutting upper die 51.

[0041] The cutter 53 has a vertically penetrating cutter mounting hole 512, which is connected to the wire passage hole 511. The cutter 53 is vertically telescopically slidably installed in the cutter mounting hole 512 through the telescopic rod 52, and works with the wire passage hole 511 in the upper die 51 to cut the wire, thereby forming an internal cutting die structure.

[0042] A straightening guide wire feeding device 60 is connected between the wire outlet end of the wire feeding device 30 and the wire inlet end of the wire passage hole 511 to ensure the accuracy of wire feeding from the wire feeding device 30 to the wire passage hole 511, thus ensuring the accuracy of subsequent wire bending and cutting position.

[0043] In practice, the wire sequentially passes through the feeding device 11, the straightening device, and the wire feeding device 30. The wire feeding device 30 provides driving force for the wire's movement. The wire passes through the wire-passing hole 511 inside the cutting die via the straightening guide wire feeding device 60. The wire is then precisely bent by a bending column 42 driven by a cylinder on the bending turntable 41. When the wire reaches the preset length, the telescopic rod drive mechanism drives the cutter 53 at the upper end of the telescopic rod 52 to cut the wire passing through the wire-passing hole 511 in the upper die 51, completing one product processing cycle. The equipment then automatically enters the next processing cycle, achieving continuous and efficient production.

[0044] In this embodiment, a first mounting base 44 is vertically provided at the bottom of the platform plate 12, and a turntable bushing 411 rotatably connected to the first mounting base 44 is provided at the bottom of the bending turntable 41. The telescopic rod 52 is slidably inserted inside the turntable bushing 411, and a turntable gear 412 is sleeved on the outer side of the turntable bushing 411. The turntable drive mechanism is meshed with the turntable gear 412 through a drive gear 431.

[0045] The turntable drive mechanism includes a turntable drive motor 43 and a drive gear 431. The turntable drive motor 43 is vertically mounted on the first mounting base 44, and the drive gear 431 is connected to the shaft end of the turntable drive motor 43.

[0046] In practical implementation, both the turntable gear 412 and the drive gear 431 are high-precision ground gears, and the turntable drive motor 43 is a servo motor. The high-precision ground gears ensure stable and accurate rotational transmission of the bending turntable 41. Under the control of the CNC system, the servo motor can accurately control key parameters such as the rotation angle of the bending turntable 41, the bending angle and position of the wire, etc., to meet the bending requirements of various complex-shaped products. The bending column 42 is driven and lifted by a high-speed cylinder, which greatly improves bending efficiency while ensuring bending accuracy, and meets the standard production speed.

[0047] In addition, the bending column 42 is detachably mounted on the bending turntable 41, and bending columns 42 of different sizes and shapes can be replaced to meet the bending needs of various complex-shaped products.

[0048] In this embodiment, a second mounting base 56 is vertically provided at the bottom of the first mounting base 44. The telescopic rod drive mechanism includes a hinged link structure 54 and a telescopic rod drive motor 55. The hinged link structure 54 is vertically disposed on the second mounting base 56. The upper end of the hinged link structure 54 is fixedly connected to the lower end of the telescopic rod 52. The telescopic rod drive motor 55 is horizontally and vertically disposed at the bottom of the second mounting base 56. The shaft end of the telescopic rod drive motor 55 is provided with a connecting cam 551. The shaft end of the connecting cam 551 is connected to the lower end of the hinged link structure 54 through a bearing.

[0049] The hinged linkage structure 54 includes an upper linkage 541 and a lower linkage 542 that are hinged together. The upper linkage 541 is connected to the telescopic rod 52, and the lower linkage 542 is connected to the connecting cam 551. A guide rail slider 543 is provided on one side of the upper linkage 541 and is connected to the inner side of the second mounting seat 56.

[0050] In practice, the wire cutting method adopts a cam-linkage structure, which efficiently converts the cam rotational motion into the linkage linear motion, driving the telescopic rod 52 to move up and down reciprocally within the turntable bushing 411. This causes the cutter 53 at the upper end of the telescopic rod 52 to work with the upper die 51 to cut the wire passing through the wire hole 511, achieving fast and accurate cutting and greatly improving production speed.

[0051] In this embodiment, the cable adjustment device 20 includes a cable adjustment plate group 21 connected to one side of the platform plate 12 and a plurality of straightening pressure roller groups 22 disposed opposite to each other on the side end face of the cable adjustment plate group 21. The straightening pressure roller group 22 adjusts the clamping force through spring pressure blocks.

[0052] In practice, the wire enters the wire straightening device 20 stably from the feeding device 11. The wire straightening plate group 21 consists of two vertically connected horizontal and vertical wire straightening plates. Multiple oppositely arranged straightening pressure roller groups 22 are provided on one side end face of both the horizontal and vertical wire straightening plates to straighten the bending of the wire and provide wire with straightness that meets the standards for subsequent processes.

[0053] like Figures 1 to 9 As shown in the figure, in this embodiment, the wire feeding device 30 includes two sets of wire feeding rollers 31 and a wire feeding drive motor 32. The two sets of wire feeding rollers 31 are arranged in parallel and opposite to each other on the upper surface of the platform plate 12. The wire feeding drive motor 32 drives the two sets of wire feeding rollers 31 to rotate in opposite directions through a gear transmission structure.

[0054] In practice, the wire feeding drive motor 32 drives two sets of wire feeding rollers 31 to rotate in opposite directions through high-precision ground gears, providing stable feeding power for the movement of the wire. The two sets of wire feeding rollers 31 can be flexibly adjusted, and the operator can adjust them in real time according to the characteristics of different wires and the flatness requirements of the product, ensuring the level of the wire feeding process and effectively improving the flatness of the product.

[0055] In this embodiment, a first straightening guide block 33 is provided between a set of wire feeding pressure rollers 31 and one end of the adjustment device, and a second straightening guide block 34 is provided between the two sets of wire feeding pressure rollers 31. The first straightening guide block and the second straightening guide block 34 are provided with straightening holes (not shown in the view).

[0056] In practice, to ensure accurate straightening of the wire, after the wire is straightened and sent out from the straightening device 20, the straightening accuracy of the wire can be further corrected by passing through the first straightening guide block 33 and the second straightening guide block 34.

[0057] In this embodiment, the straightening and guiding wire feeding device 60 includes an elongated guide block 61. The elongated guide block 61 has a straight groove 62 extending through it along its length. One end of the elongated guide block 61 is connected to the wire outlet end of the wire feeding device 30, and the other end is connected to the wire inlet end of the wire cutting die. The straight groove 62 and the wire passage hole 511 are aligned. The straightening and guiding wire feeding device 60 further ensures the straightening accuracy of the wire, provides a precise angle for bending and forming, and provides precise positioning for the cutting position.

[0058] Where there is no conflict, the above embodiments and features can be combined with each other.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
