Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a wire bending tool. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of an iron core (or magnetic core) and a coil.

[0003] After the coil is wound, existing transformers require axial extensions at the top and bottom of the coil. Because the copper flat wire for these axial extensions needs to be perpendicular to the coil, the flat wire must be folded at a 90° angle across its width, a process typically requiring specialized tools.

[0004] The utility model patent with announcement number CN206854531U proposes that a transformer wire bending wrench belongs to the field of tools and includes two parts: a straight handle and a curved handle. A vertical front clamping column is connected to the front end of the curved handle, and a vertical rear clamping column is connected to the lower end surface of the straight handle behind the bent section of the curved handle. The two handles between the front and rear clamping columns are flexibly connected by bolts and nuts. The curved handle is a Z-shaped rectangular parallelepiped, with the upper and lower sections parallel to each other, the upper section being shorter and the lower section being longer; the straight handle is a rectangular parallelepiped, with the straight handle on top and the curved handle on the bottom. A through hole is provided on the upper end surface between the front clamping column and the bent section of the curved handle, and a through hole is provided between the front end of the straight handle and the rear clamping column. A screw passes through the two through holes, and its end extends out of the upper end surface of the straight handle and is screwed with a nut. When the straight and curved handles are superimposed on each other, the front end of the straight handle is located behind the front clamping column of the curved handle. When winding transformer windings, this wrench ensures that the flat wire is smoothly bent, while saving effort and labor, thereby improving production efficiency. Although this wire bending tool is easy to operate, it still has the following drawbacks: first, the bent flat wire becomes skewed at the bend corner, and it is inconvenient to correct the skew by tapping it, as tapping is strictly prohibited on the transformer body; second, bending the wire is very laborious, mainly because the upper bending handle is restricted by other structures during the rotation process of the flat wire, making it difficult to operate at certain angles and difficult to apply force. Moreover, when bending thick flat wires, a very large force must be applied to bend the flat wire, which is very laborious.

[0005] Therefore, it is necessary to produce a tool that can solve this problem by bending the flat wire without manually applying pressure and preventing the flat wire from being skewed during bending. Summary of the Invention

[0038] The present invention provides a wire bending tool.

[0039] Please refer to Figures 1 to 9 The wire bending tool comprises a movable platform 4, a wire bending assembly 1 is provided on the platform 4, a steering assembly 2 is provided on one side of the wire bending assembly 1 for driving the wire bending assembly 1 to rotate, and a lifting assembly 3 is provided on the side of the steering assembly 2 facing away from the wire bending assembly 1 for adjusting the horizontal height of the steering assembly 2 to drive the wire bending assembly 1 to move up and down;

[0040] The wire bending assembly 1 includes a first wire bending tube 11, a second wire bending tube 12 is provided at one end of the first wire bending tube 11, the extension direction of the first wire bending tube 11 and the extension direction of the second wire bending tube 12 are on the same straight line, and the first wire bending tube 11 and the second wire bending tube 12 are both formed with an opening 15 on the same side for the flat wire to enter the first wire bending tube 11 and the second wire bending tube 12 and to move out of the first wire bending tube 11 and the second wire bending tube 12. The first wire bending tube 11 and the second wire bending tube 12 are hingedly connected by a hinge 13. The wire bending assembly 1 also includes a transmission component 14 for driving the second wire bending tube 12 to rotate along the rotating axis of the hinge 13;

[0041] The lifting assembly 3 includes a base column 31 vertically arranged on the platform 4, and the base column 31 is recessed on the side away from the platform 4 to form a sliding hole 32, and a sliding column 33 is slidingly provided in the sliding hole 32. The lifting assembly 3 also includes a lifting component for driving the end of the sliding column 33 away from the bottom of the sliding hole 32 to slide toward the side close to or away from the bottom of the sliding hole 32. The steering assembly 2 includes a support rod 21, one end of the support rod 21 is connected to the end of the sliding column 33 away from the bottom of the hole, and the other end is hinged to the end of the first bending tube 11 away from the second bending tube 12. The support rod 21 is also provided with a deflection component 22 for driving the first bending tube 11 to rotate toward or away from the support rod 21.

[0042] In the technical solution of the present invention, when bending the flat wire, the flat wire is placed into the first bending tube 11 and the second bending tube 12 through the opening 15, and the position where the flat wire needs to be bent is at the junction of the first bending tube 11 and the second bending tube 12. Then the transmission component 14 drives the second bending tube 12 to rotate with the hinge 13 as the axis away from one end of the first bending tube 11. When the second bending tube 12 rotates, it drives the flat wire to move together. At this time, the flat wire located in the first bending tube 11 does not move, and the flat wire located in the second bending tube 12 moves with the second bending tube 12. When the second bending tube 12 rotates, the flat wire will be bent at the intersection of the first bending tube 11 and the second bending tube 12. The intersection is the bending point. After the flat wire is bent, it passes through the opening 15 to separate from the first bending tube 11 and the second bending tube 12. The entire process does not require manual force to bend the flat wire. The lifting component 3 is used to make the bending component 1 suitable for bending wire harnesses at different heights. The steering component 2 is used to adjust the angle of the bending component 1 so that the bending component 1 can be suitable for bending flat wires at various angles. Through the mutual cooperation between the above structures, the bending of the flat wire can be achieved, and the entire bending process of the flat wire is mechanically driven bending, without the need for manual force. At the same time, the mechanical bending method can avoid the situation where the angle change during manual bending will cause the flat wire to be skewed.

[0043] Please refer to the attached Figure 2-3The transmission component 14 includes a first gear 141 rotatably arranged on the side of the second bending tube 12 away from its own opening 15 and near a corner of the hinge 13. A first through-slot 141a is formed through the first gear 141. A transmission rod 146 is fixed on the same side of the second bending tube 12 and the first gear 141. The transmission rod 146 is used to slide in the first through-slot 141a. The first bending tube 11 is rotatably connected to the side away from the opening 15 with the second gear 142. The second gear 142 is meshed with the first gear 141. A first motor 145 is provided on the same side of the first bending tube 11 and the second gear 142. A bevel gear 144 is provided on the output shaft of the first motor 145. A gear ring 143 is provided on the side of the second gear 142 away from the first bending tube 11, and the bevel gear 144 is meshed with the gear ring 143. After the flat wire is placed in the first bending tube 11 and the second bending tube 12, and when the flat wire needs to be bent, the first motor 145 is started, so that the first motor 145 drives the bevel gear 144 to rotate, the rotation of the bevel gear 144 drives the gear ring 143 to rotate, the rotation of the gear ring 143 drives the second gear 142 to rotate, the rotation of the second gear 142 drives the first gear 141 to rotate, when the first gear 141 rotates, the first through slot 141a conflicts with the transmission rod 146, and the first through slot 141a of the first gear 141 rotates. 41 remains unchanged, and its direction rotates along with the rotation of the first gear 141. When the first through slot 141a rotates, the transmission rod 146 will be driven to slide in the first through slot 141a. However, the position of the transmission rod 146 on the second wire bending tube 12 remains unchanged. The sliding of the transmission rod 146 in the first through slot 141a will drive the second wire bending tube 12 to rotate around the hinge 13 as the axis. Thus, when the first wire bending tube 11 is stationary, the second wire bending tube 12 is driven to rotate, so that the second wire bending tube 12 bends the flat wire.

[0044] Please refer to the attached Figure 3 Pressure sensors are located on the walls of both ends of the first through-slot 141a. These pressure sensors are electrically connected to the motor via a controller. When the transmission rod 146 contacts any pressure sensor within the first through-slot 141a and the pressure detected by the pressure sensor exceeds a preset value, the pressure sensor transmits a signal to the controller, which then stops the first motor 145. This prevents overload and damage to the first motor 145.

[0045] Please refer to the attached Figure 4The extension direction of the rotation axis of the support rod 21 and the first bending tube 11 is perpendicular to the extension direction of the rotation axis of the first bending tube 11 and the second bending tube 12. A second through groove 23 is formed on one side of the rod wall of the support rod 21. The extension direction of the second through groove 23 is parallel to the extension direction of the rotation axis of the support rod 21 and the first bending tube 11. The deflection component 22 includes a sliding rod 221 slidably arranged in the second through groove 23, and the two ends of the sliding rod 221 extend out of the second through groove 23 and are respectively connected to the connecting rod 226 for rotation. The end of the connecting rod 226 facing away from the sliding rod 221 is rotatably connected to the outer wall of the first bending tube 11. The deflection component 22 also includes a positioning component 26 for positioning the position of the sliding rod 221. The sliding rod 221 slides in the second through groove 23, and can drive the connecting rod 226 to move together. The movement of the connecting rod 226 can drive the first bending tube 11 to rotate around the hinge point, so that the first bending tube 11 rotates toward or away from the support rod 21. The positioning component 26 can fix the position of the sliding rod 221 to fix the deflection angle of the first bending tube 11.

[0046] Please refer to the attached Figure 5 A third through slot 25 connected to the second through slot 23 is formed on the rod wall on the other side of the support rod 21, and the groove wall extension direction of the third through slot 25 is the same as the groove wall extension direction of the second through slot 23. The positioning component 26 includes a connecting rod 222 that slides in the third through slot 25 and is connected to the sliding rod 221. The end of the connecting rod 222 facing away from the sliding rod 221 is provided with a support plate 224, and the support plate 224 is provided with a first push plate 223 on the side close to the support rod 21. The support plate 224 is threadedly connected to the first threaded rod 225 on the side facing away from the support rod 21, and the end of the first threaded rod 225 close to the support rod 21 is rotatably connected to the first push plate 223. By rotating the first threaded rod 225, the first push plate 223 moves toward the side close to the support rod 21, so that the first push plate 223 contacts the rod wall of the support rod 21. When the first push plate 223 contacts the support rod 21, the sliding rod 221 is driven to move toward the side close to the first push plate 223, so that the first push plate 223 and the sliding rod 221 clamp the rod wall of the support rod 21 to fix the position of the sliding rod 221.

[0047] Please refer to the attached Figure 4 The support rod 21 and the third through slot 25 are recessed on the same side to form a receiving slot 24 for receiving the transmission component 14. The third through slot 25 is located in the receiving slot 24. The arrangement of the receiving slot 24 enables the transmission component 14 to enter the receiving slot 24 when it approaches the support rod 21.

[0048] Please refer to the attached Figure 6An anti-slip layer is provided on the side of the first push plate 223 close to the support rod 21 and on the side of the slide bar 221 connected to the connecting rod 222 and close to the wall of the second through slot 23. The anti-slip layer increases the friction between the first push plate 223 and the support rod 21 and between the slide bar 221 and the wall of the second through slot 23, further securing the position of the slide bar 221.

[0049] Please refer to the attached Figure 7 A second push plate 6 is provided in the first bending tube 11, and the second push plate 6 is rotatably connected to the second threaded rod 7 close to the tube wall of the first bending tube 11, and the end of the second threaded rod 7 facing away from the second push plate 6 is threadedly engaged with and penetrates the tube wall of the first bending tube 11, and extends to the outer wall of the first bending tube 11; a third push plate 8 is provided in the second bending tube 12, and the third push plate 8 is rotatably connected to the third threaded rod 9 close to the tube wall of the second bending tube 12, and the end of the third threaded rod 9 facing away from the third push plate 8 is threadedly engaged with and penetrates the tube wall of the second bending tube 12, and extends to the outer wall of the second bending tube 12. After the flat wire is located in the first bending wire tube 11 and the second bending wire tube 12, the second push plate 6 is moved toward the side close to the flat wire by rotating the second threaded rod 7, so that the second push plate 6 conflicts with the flat wire located in the first bending wire tube 11, and the third push plate 8 is moved toward the side close to the flat wire by rotating the third threaded rod 9, so that the third push plate 8 conflicts with the flat wire located in the second bending wire tube 12, so as to clamp the flat wire and prevent the flat wire from shifting when bending, and at the same time, it can realize bending of flat wires of different thicknesses.

[0050] Please refer to the attached Figure 8-9 A mounting hole 34 is formed on one side of the sliding column 33 near the bottom of the sliding hole 32. The lifting component includes a column 35 vertically arranged at the bottom of the sliding hole 32 and located in the mounting hole 34.
