Description

Technical Field

[0001] This utility model relates to the field of inductor flat wire bending and forming technology, and in particular to an inductor flat wire bending and forming fixture. Background Technology

[0002] In the production of high-power inductors, bending and forming flat wires is one of the key processes.

[0003] Currently, bending is generally carried out by hand or with the aid of simple tooling. On the one hand, hand bending relies on the experience and skills of workers, and it is difficult to control the force and angle precisely, resulting in large deviations in the dimensions of the bent flat wire, poor consistency, unstable product quality, and high rework rate. On the other hand, when bending with simple tooling, one tooling is often only suitable for bending flat wire of a specific specification. When the product specification changes, the tooling needs to be redesigned and remade. The tooling has poor versatility, is costly, time-consuming and labor-intensive, which seriously affects production efficiency and the economic benefits of enterprises. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an inductor flat wire bending and forming fixture to solve the technical problems of unstable quality of flat wire products after manual bending in the prior art and poor tooling versatility when bending and forming with simple tooling.

[0005] This utility model provides an inductor flat wire bending and forming fixture, including a base, a support component disposed on the base, and forming components disposed on both sides of the support component. The forming components are rotatably connected to the base, and the forming components and the support component are spaced apart. The support assembly includes a support plate and a pad at one end of the support plate. The support plate has two positioning grooves, which together with the pad form a receiving space to accommodate the inductor flat wire. The support plate is detachably connected to the base. The molding assembly includes a positioning plate, and the support plate and the positioning plate are spaced apart.

[0006] The aforementioned inductor flat wire bending and forming fixture uses a space on a support plate to accommodate the inductor flat wire, allowing the support component to support and limit the inductor. The forming component is rotatably connected to the base to bend the protruding flat wire leads of the inductor, replacing purely manual bending and improving the quality stability of the bent flat wire product. Secondly, different support plates can accommodate inductors of different sizes. The detachable connection between the support plate and the base allows for quick assembly, disassembly, and replacement of support plates of different specifications. This makes the inductor flat wire bending and forming fixture in this solution adaptable to inductors of different sizes, improving the tooling versatility. It solves the technical problems of unstable quality of flat wire products after purely manual bending and poor tooling versatility when using simple tooling for bending in existing technologies.

[0007] In addition, the inductor flat wire bending and forming fixture described above according to this utility model may also have the following additional technical features: Furthermore, the base includes a base plate with multiple limiting holes, and the bottom of the support plate has multiple limiting posts. The limiting posts are detachably connected to the limiting holes so that the support plate and the base are detachably connected.

[0008] Furthermore, the molding assembly also includes a pressure bar, which is located on the side of the positioning plate away from the support assembly and is angled to the positioning plate.

[0009] Furthermore, the positioning plate has a first positioning hole at one end near the pressure rod, and the inductor flat wire bending forming fixture also includes a positioning pin, which is adapted to the first positioning hole and fixedly connected to the base so that the forming component is rotatably connected relative to the base.

[0010] Furthermore, the base plate is provided with a second positioning hole, which corresponds one-to-one with the first positioning hole so that the positioning pin is fixedly connected to the base.

[0011] Furthermore, the two molding components are symmetrically arranged relative to the supporting component.

[0012] Furthermore, the spacing between the support plate and the positioning plate is not less than the thickness of the flat wire.

[0013] Furthermore, the support plate includes a support portion and a limiting portion disposed at one end of the support portion. The limiting portion and the pad are disposed at opposite ends of the support portion. The limiting portion and the pad are respectively provided with limiting protrusions, which are used to limit the inductor.

This solves the technical problems of unstable product quality after manual bending of flat wires and the poor tooling versatility when using simple tooling for bending.

[0022] To facilitate understanding of this utility model, several embodiments are provided below. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0023] Example 1 Please see Figures 1-7 The image shows an inductor flat wire bending and forming fixture in the first embodiment of the present invention, including a base 100, a support component 200 disposed on the base 100, and forming components 300 disposed on both sides of the support component 200; further, the two forming components 300 are symmetrically arranged relative to the support component 200.

[0024] In this embodiment, the molding component 300 is rotatably connected to the base 100, and the molding component 300 and the support component 200 are spaced apart. Further, the support component 200 includes a support plate 210 and a pad 230 disposed at one end of the support plate 210, and the molding component 300 includes a positioning plate 310, with the support plate 210 and the positioning plate 310 spaced apart. As a specific example, the support plate 210 is provided with two positioning grooves 220, which, together with the pad 230, form a receiving space to accommodate the inductor flat wire. The support plate 210 and the base 100 are detachably connected so that different models of support plates can be replaced according to different sizes of inductors, improving the versatility of the molding fixture in this solution.

[0025] As a specific example, in order to facilitate the rotation of the positioning plate 310 to achieve the bending of the flat wire leads of the inductor, it should be further noted that the spacing between the support plate 210 and the positioning plate 310 is not less than the thickness of the flat wire.

[0026] To ensure efficiency and accuracy of bending angle by limiting the inductor during flat wire bending, in this embodiment, the support plate 210 includes a support portion 211 and a limiting portion 212 located at one end of the support portion 211. A positioning groove 220 is provided on the support portion 211. The limiting portion 212 and the pad 230 are located at opposite ends of the support portion 211, and both the limiting portion 212 and the pad 230 are provided with limiting protrusions 240 to limit the inductor. Furthermore, since an inductor typically has two coils, as a specific example, the support portion 211 has two positioning grooves 220, which are symmetrically arranged.

[0027] Furthermore, the forming assembly 300 also includes a pressure rod 320, which is located on the side of the positioning plate 310 away from the support assembly 200 and is angled to the positioning plate 310. To facilitate control of the bending angle of the flat wire when rotating the forming assembly 300, in this embodiment, the pressure rod 320 is angled to the positioning plate 310, and the end of the pressure rod 320 away from the positioning plate 310 is connected to a cylinder. The cylinder's extension and retraction causes the forming assembly 300 to rotate around the positioning pin, thereby bending the flat wire. Furthermore, using a cylinder to rotate the pressure rod 320 to bend the positioning plate 310 not only ensures the flat wire is bent correctly and deformed evenly, but also easily meets the bending requirements of thicker, higher-strength flat wires for high-power inductors.

[0028] Furthermore, the positioning plate 310 has a first positioning hole 330 at one end near the pressure rod 320. The inductor flat wire bending and forming fixture also includes a positioning pin, which is adapted to the first positioning hole 330 and fixedly connected to the base 100 so that the forming component 300 is rotatably connected relative to the base 100. Next, the base plate 110 has a second positioning hole 130, which corresponds one-to-one with the first positioning hole 330 so that the positioning pin is fixedly connected to the base 100.

[0029] To facilitate quick assembly and disassembly of the support plate 210 and the floor on the base 100, the base plate 110 on the base 100 is further provided with multiple limiting holes 140, and the bottom of the support plate 210 is provided with multiple limiting posts (not shown in the figure). The limiting posts and limiting holes 140 are detachably connected and matched one by one so that the support plate 210 and the base 100 can be detachably connected.

[0030] To facilitate fixing the molding fixture to the operating table, in this embodiment, the base 100 further includes a fixing plate 120. The fixing plate 120 is located on the side of the base plate 110 away from the support assembly 200. The fixing plate 120 is clamped by a clamping mechanism on the operating table to fix the molding fixture to the operating table. Specifically, in this embodiment, the clamping mechanism can be a bench vise. The fixing plate 120 is clamped by the bench vise to fix the molding fixture to the operating table.

[0031] As a specific example, the base plate 110 is also provided with several functional holes to realize the fixed installation of the fixing plate 120, the pad 230 and the base plate 110.

[0032] In summary, the inductor flat wire bending and forming fixture in the above embodiments of this utility model accommodates the inductor flat wire in the receiving space on the support plate so that the support component supports and limits the inductor. Then, the forming component is rotatably connected to the base to bend the protruding flat wire leads of the inductor, replacing purely manual bending and improving the quality stability of the bent flat wire product. Secondly, different support plates can be adapted to inductors of different sizes. The support plate and the base are detachably connected to achieve quick disassembly and replacement of support plates of different specifications. Thus, the inductor flat wire bending and forming fixture in this solution can be adapted to inductors of different sizes, improving the tooling versatility. It solves the technical problems of unstable quality of flat wire products after purely manual bending in the prior art and poor tooling versatility when bending and forming with simple tooling.
