[0030] 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.

[0031] like Figures 1 to 4 As shown, a 3D wire bending and forming machine includes a frame 10, a straightening and feeding device 20, a steering device 30, and a bending and cutting device 40.

[0032] A machine frame 10 is provided with a machine housing 11 on one side, and a wire inlet hole 12 is provided on one side of the machine housing 11. A straightening and feeding device 20 is installed on the machine frame 10, and the discharge end of the straightening and feeding device 20 is located on one side of the wire inlet hole 12.

[0033] A steering device 30 is mounted on the housing 11. The steering device 30 includes a rotary spindle 31, a turntable 32, and a rotary drive motor 33. The rotary spindle 31 is rotatably mounted inside the housing 11 via a bearing seat. One end of the rotary spindle 31 is provided with the turntable 32, which is rotatably mounted on one side of the housing 11. A mounting plate 34 is vertically mounted on the outer side of the turntable 32. The rotary drive motor 33 is located inside the housing 11 below the rotary spindle 31 and is connected to the other end of the rotary spindle 31 via a belt drive. The rotary spindle 31 has a wire passage 35 inside. The turntable 32 has a wire outlet hole 321 at its center that communicates with the wire passage 35. The center points of the wire passage 35, the wire outlet hole 321, and the wire inlet hole 12 are on the same straight line.

[0034] The bending and cutting device 40 is vertically connected to the mounting plate 34. The bending and cutting device 40 includes a cutting mechanism 41 and a bending mechanism 42. The cutting mechanism 41 is provided with a cutter inlet hole 411, and the bending mechanism 42 is provided with a bending slot 421. The center points of the outlet hole 321, the cutter inlet hole 411 and the bending slot 421 are on the same straight line.

[0035] In practice, the linear metal enters from the feed end of the straightening and feeding device 20, straightens and moves the linear metal, and enters the interior of the rotary spindle 31 through the wire inlet hole 12. It is then led out from the wire outlet hole 321 in the center of the turntable 32, passes through the cutter wire inlet hole 411 and the bending slot 421, and is bent on the first reference plane by the bending mechanism 42. Then, the bending and cutting device 40 is rotated by the steering device 30, so that the bending mechanism 42 bends the linear metal on other reference planes, thereby bending a wire with a three-dimensional structure.

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the straightening and feeding device 20 includes a pressure roller straightening mechanism 21 and a pressure roller wire feeding mechanism 22. The pressure roller straightening mechanism 21 is set at the feeding end of the pressure roller wire feeding mechanism 22 through a connecting plate, which makes the structure compact, easy to install, and saves equipment space.

[0037] Specifically, the pressure roller straightening mechanism 21 includes a straightening bracket 211. A connecting vertical plate 212 and a connecting flat plate 213 are fixedly connected between the straightening brackets 211. A plurality of horizontal straightening rollers 214 are provided on one side end face of the connecting vertical plate 212, and a plurality of vertical straightening rollers 215 are provided on the upper end face of the connecting flat plate 213, and the plurality of horizontal straightening rollers 214 and the plurality of vertical straightening rollers 215 are all tangent to the same straight line.

[0038] Among them, multiple horizontal straightening rollers 214 and multiple vertical straightening rollers 215 can adjust the clamping force through spring pressure blocks, thereby applying pressure to the linear metal and straightening any bent parts.

[0039] Specifically, the pressure roller feeding mechanism 22 includes a mounting plate 221, two sets of feeding pressure rollers 222 and a feeding drive motor 223. The two sets of feeding pressure rollers 222 are arranged in parallel and opposite to each other on one side of the mounting plate 221. The feeding drive motor 223 drives the two sets of feeding pressure rollers 222 to rotate in opposite directions through a gear transmission structure 224, thereby driving the linear metal line to move between the two sets of feeding pressure rollers 222.

[0040] like Figure 3 and Figure 7 As shown, in this embodiment, the cutting mechanism 41 includes a fixed cutter 412, a movable cutter 413, and a cutter cylinder 414. The fixed cutter 412 is disposed on the upper end of the mounting plate 34. The movable cutter 413 overlaps with the fixed cutter 412 and passes through the upper end of the mounting plate 34. The cutter cylinder 414 is disposed on the bottom of the mounting plate 34 through a mounting base. The piston rod end of the cutter cylinder 414 is connected to the lower end of the movable cutter 413. The cutter inlet hole 411 is disposed in the fixed cutter 412 and the movable cutter 413.

[0041] In practice, the movable cutter 413 can be raised and lowered on the mounting plate 34 via the cutter cylinder 414, thereby cooperating with the fixed cutter 412 to cut the linear metal in the cutter inlet hole 411.

[0042] like Figure 3 , Figure 8 and Figure 9 As shown, in this embodiment, the bending mechanism 42 includes a sliding sleeve 422, a rotating sleeve 423, a bending shaft 424, and a shaft motor 425. The upper end of the sliding sleeve 422 is fixedly mounted on the mounting plate 34. Telescopic cylinders 426 are fixedly mounted on both sides of the sliding sleeve 422. A motor base plate 427 is provided at the output shaft end of the telescopic cylinder 426. The rotating sleeve 423 is nested in the inner hole of the sliding sleeve 422, and the bending shaft 424 slides through the inner hole of the rotating sleeve 423. The lower end of 4 is fixedly connected to the motor base plate 427. The upper end of the bending shaft 424 is provided with a bending slot 421 and protrudes from the upper surface of the mounting plate 34. A first transmission gear 4241 is sleeved on the bending shaft 424. The first transmission gear 4241 is located below the rotating sleeve 423. The rotating shaft motor 425 is vertically connected to the motor base plate 427. The shaft end of the rotating shaft motor 425 is provided with a second transmission gear 4251 that meshes with the first transmission gear 4241.

[0043] In practice, the rotating shaft motor 425 drives the bending shaft 424 to rotate through the transmission gear structure, and performs bending processing on the linear metal located in the bending slot 421. The bending shaft 424 is driven to retract downward by the telescopic cylinder 426, thereby controlling the bending shape of the linear metal.

[0044] The 3D wire bending forming machine provided by this utility model, compared with the prior art, has a steering device 30 including a rotary spindle 31, a turntable 32 and a rotary drive motor 33. The rotary spindle 31 is rotatably mounted inside the machine housing 11 through a bearing seat. One end of the rotary spindle 31 is provided with the turntable 32, and the other end is connected to the rotary drive motor 33 through a belt drive. This can effectively improve the rotation speed of the turntable 32, optimize the size of the equipment, and save on production and manufacturing costs.

[0045] Where there is no conflict, the above embodiments and features can be combined with each other.

[0046] 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.
