Technical Field

[0001] The present application relates to the technical field of flat wire processing, and in particular to a flat wire bending device. Background Art

[0002] Flat wire, also known as flat wire, flattened wire, flat-angle wire, or ultra-narrow strip, is a shaped metal wire with a roughly rectangular cross-section. As a metal wire with unique properties and a wide range of applications, flat wire plays a vital role in modern industry and electronics.

[0003] Flat wire is typically straight when produced and often requires bending to achieve the desired curved shape. Existing bending equipment typically consists of a clamp, a bending unit, a rotary drive, and a conveyor mechanism for conveying the flat wire. The clamp positions and clamps the flat wire, and the rotary drive rotates the bending unit to bend the flat wire. Once bent, the conveyor mechanism removes the flat wire from the clamp.

[0004] Regarding the above-mentioned related technologies, the existing conveying mechanism of the flat wire usually adopts a conveyor belt, a driving roller, etc., which causes serious wear to the flat wire during conveyance. Utility Model Content

[0016] By adopting the above technical solution, the first guide wheel is arranged horizontally, which facilitates the horizontal loading of the flat wire to the pressure-feeding positioning plate, thereby improving the loading efficiency of the flat wire to the pressure-feeding positioning plate. The setting of the second guide wheel can limit the radial direction of the flat wire, thereby reducing the probability of horizontal movement of the flat wire, and further improving the loading efficiency of the flat wire.

[0017] Optionally, the first guide wheels are arranged on opposite sides of the second guide wheel along the conveying direction of the flat wire.

[0018] By adopting the above technical solution, the first guide wheels are respectively arranged on both sides of the second guide wheel, which can make the feeding of the flat wire smoother and more stable.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The embodiment of the present application discloses a flat wire bending device.

[0040] Reference Figure 1 A flat wire bending device includes a positioning fixture 1, a rotating mechanism 2 coaxially sleeved on the positioning fixture 1, a conveying mechanism 3 for conveying the flat wire, and an abutting mechanism 4 for pressing the flat wire.

[0041] Reference Figure 2 and Figure 3The positioning fixture 1 is fixed to the work platform with its axis arranged vertically. The top of the positioning fixture 1 has a positioning slot 11 for the flat wire to pass through. The positioning slot 11 includes a first slot 111 and a second slot 112 in sequence along the conveying direction. The radial width of the second slot 112 is adapted to the width of the flat wire, and the radial width of the first slot 111 is greater than the width of the flat wire. The end of the flat wire can be guided into the first slot 111 through the first slot 111. The positioning fixture 1 is also fixed with a positioning cover plate 12 covering the positioning slot 11.

[0042] The positioning fixture 1 is further rotatably provided with two positioning wheels 13 on one side of the positioning slot 11 , and the positioning wheels 13 are symmetrically arranged along the axis of the positioning fixture 1. The two positioning wheels 13 form a gap for the flat wire to pass through, and the gap corresponds to the first slot 111.

[0043] The structure of the rotating mechanism 2 is consistent with the bending rotating member of the prior art, and includes a rotating driving member 21, a rotating disk 22 connected to the output shaft of the rotating driving member 21, and a bending member 23 provided on the top of the rotating disk 22. The rotating driving member 21 is a combination of a rotating motor and a reducer.

[0044] The rotating disk 22 and the positioning fixture 1 rotate in unison, with the top surface of the rotating disk 22 lower than the top surface of the positioning fixture 1. The bending member 23 is cylindrical and circumferentially fixed along the axis of the rotating disk 22. The sidewall of the bending member 23 defines a guide ring groove 231 for the flat wire to abut. The guide ring groove 231 and the positioning slot 11 are located at the same level.

[0045] Reference Figure 4 The conveying mechanism 3 includes a conveying component 31 arranged along the flat wire conveying direction, a pressing component 32 slidably installed on the conveying component 31 , and a guide component 33 arranged on the pressing component 32 .

[0046] The conveyor assembly 31 has the same structure as conventional linear modules, comprising a conveyor track 311, a conveyor slider 312 slidably mounted on top of the conveyor track 311, and a sliding drive 313 that drives the conveyor slider 312 horizontally. In this embodiment, the sliding drive 313 is a combination of a rotary motor and a reducer, which drives the conveyor slider 312 through the engagement of a screw and nut. The detailed structure is not described here.

[0047] Reference Figure 4 and Figure 5The pressure feed assembly 32 includes a pressure feed positioning plate 321 fixed to the conveying slide 312, a fixed plate 322 mounted on the pressure feed positioning plate 321, and a pressure plate 323 mounted on the fixed plate 322. The pressure feed positioning plate 321 is a rectangular plate extending along the length of the conveying track 311. The pressure feed positioning plate 321 and the conveying slide 312 are fixed by bolts. The fixed plate 322 is fixed above the pressure feed positioning plate 321 via a plurality of connecting posts 324.

[0048] A lifting drive 325, a conventional lifting motor, is vertically fixed to the top of the fixed plate 322. The output shaft of the lifting drive 325 is fixedly connected to the pressure plate 323. The top of the pressure-feed positioning plate 321 has a pressing surface 3211 corresponding to the pressure plate 323. Once the flat wire is loaded onto the pressure-feed positioning plate 321, the lifting drive 325 is activated, pressing the pressure plate 323 against the pressing surface 3211. The flat wire is then conveyed to the positioning fixture 1 via the conveyor assembly 31.

[0049] The guide assembly 33 is located entirely on the side of the pressure-feeding positioning plate 321 away from the positioning fixture 1. It includes a first guide wheel 331 and at least two sets of second guide wheels 332. The at least two sets of guide wheels are spaced apart along the length of the pressure-feeding positioning plate 321. Each set of second guide wheels 332 includes two symmetrically arranged second guide wheels 332. The axes of the second guide wheels 332 are arranged vertically, and each set of second guide wheels 332 has a limiting gap 333 that limits the radial direction of the flat wire. The limiting gap 333 corresponds to the gap between the two positioning wheels 13 on the positioning fixture 1.

[0050] Reference Figure 5 and Figure 6 The pressure-feed positioning plate 321 has a mounting surface 3212 for the second guide wheel 332. The mounting surface 3212 is lower than the pressure surface 3211, reducing sliding friction during flat wire feeding and improving feeding efficiency. The second guide wheel 332 is detachably mounted on the pressure-feed positioning plate 321 and comprises a rotating shaft and a guide sleeve that rotatably fits around the shaft. The shaft has a mounting portion 3321 at its end. The outer diameter of the mounting portion 3321 is larger than the inner diameter of the guide sleeve.

[0051] The rotating shaft has multiple mounting slots 3322 defined in the sidewall of the mounting portion 3321, arranged radially. A plunger ball 3323 is positioned within these slots. This plunger ball 3323 comprises a plunger housing, a plunger spring securing the housing, and a locking ball connected to the plunger spring. In the normal position, the locking ball protrudes from the sidewall of the mounting portion 3321.

[0052] The pressure-feed positioning plate 321 has a mounting hole 3213 on its mounting surface 3212 for inserting the mounting portion 3321. The inner wall of the mounting hole 3213 has a locking groove 3214 that engages with a locking ball. The quick assembly and disassembly of the second guide wheel 332 and the pressure-feed positioning plate 321 allows the conveyor mechanism 3 to be equipped with second guide wheels 332 of varying sizes for flat wires of varying widths, improving the conveyor mechanism 3's adaptability.

[0053] The axis of the first guide wheel 331 is horizontally arranged and perpendicular to the length of the flat wire. The first guide wheels 331 are arranged on either side of the second guide wheel 332 along the conveying direction of the conveying track 311. The first guide wheel 331, located away from the pressing surface 3211, is located at the end of the pressure-feeding positioning plate 321. This portion has two first guide wheels 331 arranged symmetrically in a vertical arrangement.

[0054] Reference Figure 7 The abutment mechanism 4 includes an abutment plate 41 fixed to the working surface and a pressing member 42 vertically arranged on the abutment plate 41. The abutment plate 41 corresponds to the pressure-feeding positioning plate 321, so that the pressure-feeding positioning plate 321 stops the conveying of the flat wire after abutting against the abutment plate 41. The bottom of the abutment plate 41 has an abutment through-hole 411 that penetrates the two side walls and is for the flat wire to pass through. The pressing member 42 is a push cylinder of the prior art, and the output shaft of the pressing member 42 is connected to a pressure block. When the flat wire is bent, the pressure block presses and fixes the flat wire to ensure the stability of the bending.

[0055] The implementation principle of a flat wire bending device in an embodiment of the present application is as follows: the flat wire is arranged on the top of the pressure-feeding positioning plate 321 through the guide assembly 33, and then the end of the flat wire is passed through the abutment through-hole 411 and is limited on the positioning fixture 1; the flat wire is then bent by the rotating mechanism 2, and after completing one bending, the bending part 23 is reset, and the sliding drive part 313 is started to drive the pressure-feeding assembly 32 to move away from the positioning fixture 1, and then the lifting drive part 325 is started to press the flat wire, and the sliding drive part 313 is started again to drive the flat wire to be transported along the extension direction of the conveying track 311, and the above-mentioned bending operation is repeated many times to obtain the required flat wire.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
