Description

Technical Field

[0001] The invention relates to the field of transformer production and manufacturing, and in particular to a conductor bending device. Background Art

[0002] Transformer winding is an important part of the transformer, and transformer winding is usually made of multiple wires in parallel. Since different parallel wires are in different areas of the leakage magnetic field, the induced electromotive force of different wires is different, resulting in an induced potential difference between the parallel wires, and then, a circulating current is generated between the parallel wires, causing current loss. In order to reduce current loss, it is necessary to transpose the parallel wires, and before transposing, each wire needs to be bent by a wire bending device.

[0003] At present, the commonly used wire bending device includes a support, a plurality of screw holes distributed on the support, and a plurality of screws matched with the plurality of screw holes. According to the size of the wire, two screw holes with appropriate distances are selected from the plurality of screw holes, and two screws are respectively fixed in the two screw holes, and the wire is placed obliquely between the two screws so that the two sides of the wire are respectively in conflict with the two screws, and the two ends of the support and the two ends of the wire are respectively held by two hands, and the two ends of the wire are respectively brought closer to the two ends of the support until the two ends of the wire are respectively parallel to the two ends of the support, and the wire is successfully bent.

[0004] Based on the above-mentioned conductor bending device, multiple screw holes are fixed on the support member. Therefore, the available screw hole spacing is limited, and thus the conductor bending radius is limited. The conductor can only be bent in a plane, and the conductor cannot be bent up and down. In addition, the above-mentioned manual bending is likely to cause differences between the bending radii of multiple conductors. Summary of the invention

In addition, the present invention can unify the bending standards of multiple wires, thereby avoiding the arbitrariness and differences in the bending of multiple wires.

[0035] The following is a detailed description of the structure and working principle of each part of the conductor bending device:

[0036] (I) Structure and working principle of the bidirectional slide rail structure 1

[0037] In the embodiment of the present invention, the bidirectional slide rail structure 1 is used to support the entire conductor bending device, and closely cooperates with other structures of the conductor bending device to achieve bending of conductors of various sizes to obtain S-bends or reverse S-bends of conductors of various radii. In addition, the bidirectional slide rail structure 1 is also used to fix other structures of the conductor bending device. The bidirectional slide rail structure 1 is a trough structure. In order to support other structures, the bidirectional slide rail structure 1 can be made of a compression-resistant and friction-resistant metal material.

[0038] In a possible design, the bidirectional slide rail structure 1 can be a metal trough with a U-shaped cross section, and the interior of the metal trough is used to place the fixed plate 2. The bidirectional slide rail structure 1 and the fixed plate 2 can slide relative to each other, so that the wire forms bends of different radii. Of course, the bidirectional slide rail structure 1 can also be other supporting structures, as long as the bidirectional slide rail structure 1 can support other structures and can slide relative to the fixed plate 2. The embodiment of the present invention does not limit the specific design of the bidirectional slide rail structure 1.

[0039] Furthermore, in order to reduce the friction between the two-way slide rail structure 1 and the fixed plate 2, and thus reduce the wear of the contact surface between the two-way slide rail structure 1 and the fixed plate, a slide rail can be provided inside each of the two sides of the two-way slide rail structure 1, through which the two-way slide rail structure 1 and the fixed plate 2 can slide better. Of course, the fixed plate can also be directly placed inside the two-way slide rail structure 1, or other designs that can reduce the friction between the two-way slide rail structure 1 and the fixed plate 2 can be adopted. The embodiment of the present invention does not limit the design of reducing friction in the two-way slide rail structure 1.

[0040] Furthermore, in order to prevent the fixed plate 2 from falling off from both ends of the two-way slide rail structure 1 when relative sliding occurs between the two-way slide rail structure 1 and the fixed plate 2, a baffle can be fixed at both ends of the two-way slide rail structure 1, and the baffle is used to limit the maximum relative displacement when the two-way slide rail structure 1 and the fixed plate 2 slide relative to each other. Of course, other designs can also be used to prevent the fixed plate 2 from falling off from the two-way slide rail structure 1, for example, a bolt can be fixed at both ends of the two-way slide rail structure 1, etc. The embodiment of the present invention does not limit the design of preventing the fixed plate 2 from falling off from the two-way slide rail structure 1.

[0041] (II) Structure and working principle of the fixing plate 2

[0042] In an embodiment of the present invention, the fixed plate 2 is used to place the conductor to be bent, and can slide relative to the bidirectional slide rail structure 1 to obtain S-bends or reverse S-bends of conductors with different radii. In addition, the fixed plate 2 is also used to fix other structures of the conductor bending device. The fixed plate 2 can be a rectangular metal plate, and the metal plate can be a pressure-resistant and wear-resistant material. The fixed plate 2 is placed inside the groove body of the bidirectional slide rail structure 1, and the bottom surface of the fixed plate 2 can contact the bottom of the groove body of the bidirectional slide rail structure 1. Of course, in order to reduce the friction between the fixed plate 2 and the bidirectional slide rail structure 1 and reduce the loss of material, the bottom surface of the fixed plate 2 can also be designed not to contact the bottom of the groove body of the bidirectional slide rail structure 1. The embodiment of the present invention is not limited here.

[0043] It should be noted that the length of the fixed plate 2 can be designed to be smaller than the length of the bidirectional slide rail structure 1, that is, to provide an appropriate space for the relative sliding between the fixed plate 2 and the bidirectional slide rail structure 1. In practical applications, the difference in length between the fixed plate 2 and the bidirectional slide rail structure 1 can be specifically designed according to the needs of the bending radius of the conductor, and the embodiment of the present invention does not limit the difference in length between the fixed plate 2 and the bidirectional slide rail structure 1.

[0044] In a possible design, in order to reduce the friction between the fixed plate 2 and the bidirectional slide rail structure 1, a groove can be designed on both sides of the fixed plate 2, and the grooves on both sides of the fixed plate 2 are matched with the slide rails inside the bidirectional slide rail structure 1 respectively. The grooves can be matched with the corresponding slide rails, so that the fixed plate 2 and the bidirectional slide rail structure 1 can slide relatively easily. Of course, other designs can also be used to allow the fixed plate 2 and the bidirectional slide rail structure 1 to slide relatively, and the embodiment of the present invention is not limited here.

[0045] Furthermore, as needed, after the fixed plate 2 and the bidirectional slide rail structure 1 are relatively slid to meet the required displacement, in order to keep the current relative displacement between the fixed plate 2 and the bidirectional slide rail structure 1 unchanged and prevent the relative displacement between the fixed plate 2 and the bidirectional slide rail structure 1 from deviating due to human factors during operation, a fixing component can be designed, and each time the fixed plate 2 and the bidirectional slide rail structure 1 are relatively slid and displaced appropriately, the fixed plate 2 and the bidirectional slide rail structure 1 can be fixed together by the fixing component.

[0046] As an example, the fixing member can be a detachable and movable fixing member. When the fixing plate 2 and the two-way slide rail structure 1 slide relative to each other and move appropriately, the two ends of the movable fixing member can be fixed to the fixing plate 2 and the two-way slide rail structure 1 respectively, so that the fixing member 2 and the two-way slide rail structure 1 do not slide relative to each other. Of course, in order to better fix the fixing member 2 and the two-way slide rail structure 1 together, multiple detachable and movable fixing members can be designed, and the multiple movable fixing members can be fixed to both sides of the fixing member 2 and the two-way slide rail structure 1 respectively.

[0047] As another example, a fixing member may be fixed on each side of the bidirectional slide rail structure 1, one end of the fixing member being fixed on the bidirectional slide rail structure 1, and the fixing member may move along with the movement of the bidirectional slide rail structure 1. When the fixing plate 2 and the bidirectional slide rail structure 1 slide relative to each other and move appropriately, the other end of the fixing member may be fixed on the fixing plate 2, and the other end of the fixing member may be detached from the fixing plate 2.

[0048] Of course, in addition to the above two examples, other designs may be used to fix the fixing plate 2 and the bidirectional sliding structure 1, and the embodiments of the present invention are not limited to these.

[0049] In a possible design, a groove may be designed on the upper surface of the fixing plate 2, and the groove may be used to place the wire to be bent. Of course, the wire to be bent may also be placed directly on the upper surface of the fixing plate 2, and the embodiment of the present invention is not limited here.

[0050] (III) Structure and working principle of the first positioning pin feeding structure 3

[0051] In the embodiment of the present invention, the first positioning pin feeding structure 3 is used to push one side of the wire to be bent so that the wire forms a bend. The first positioning pin feeding structure 3 includes a first positioning pin 31 and a first positioning machine 32 .

[0052] The first positioning machine 32 is fixed to the upper surface of the fixing plate 2. For example, the first positioning machine 32 can be welded to one side of the upper surface of the fixing plate 2. Figure 2 The first positioning machine 32 may be designed with a telescopic body, and one end of the telescopic body may be designed with a slot, which is used to fix the first positioning nail 31. The first positioning nail 31 can be pushed by the telescopic body of the first positioning machine 32 to achieve the bending of the wire. When the horizontal bending of the wire is successful, the first positioning machine 32 can retract the first positioning nail 31 to the initial position through the telescopic body. Of course, the first positioning nail 31 can also be connected to the first positioning machine 32 through other designs, as long as the first positioning machine 32 can push and retract the first positioning nail 31, and the embodiments of the present invention are not limited here one by one.

[0053] In a possible design, a protective layer may be designed on the surface of the first positioning pin 31 to prevent the wire from being squeezed by the first positioning pin 31 when the first positioning pin 31 is pushed to bend the wire horizontally, thereby damaging the insulating outer layer of the wire.

[0054] As an example, a silicone layer may be designed on the surface of the first positioning pin 31 , and when the first positioning pin 31 contacts the wire through the silicone layer, the insulating layer of the wire will not be damaged.

[0055] As another example, the first positioning pin 31 may also be made of a composite material. When the first positioning pin 31 made of the composite material contacts the wire, the insulating layer of the wire will not be damaged due to extrusion. The embodiment of the present invention does not limit the specific design of the first positioning pin 31, as long as the first positioning pin 31 does not damage the insulating outer layer of the wire during the horizontal bending of the wire.

[0056] In one possible design, the first positioning pin 31 can be a replaceable positioning pin, and various sizes of first positioning pins 31 can be designed as backup. That is, various diameters of first positioning pins 31 can be designed, and appropriate first positioning pins 31 can be selected according to wires of different diameters. For example, for wires with larger diameters, a first positioning pin 31 with a larger diameter can be selected to increase the contact area between the first positioning pin 31 and the wire, reduce the pressure of the first positioning pin 31 on the wire during horizontal bending, and avoid damage to the insulation layer of the wire. In addition, the slot at one end of the telescopic body can be designed as a movable slot, and the replaceable first positioning pin 31 can be replaced through the movable slot. Of course, the first positioning pin 31 can also be replaced by other designs, and the embodiments of the present invention are not limited here one by one.

[0057] (IV) Structure and working principle of the second positioning pin feeding structure 4

[0058] In an embodiment of the present invention, the second positioning pin feeding structure 4 is used to push the other side of the conductor to be bent so that the conductor forms another bend. Similar to the above-mentioned first positioning pin feeding structure 3, the second positioning pin feeding structure 4 includes a second positioning pin 41 and a second positioning machine 42. The second positioning machine 42 is used to push the second positioning pin 41 to perform horizontal bending on the conductor. After the horizontal bending is successful, the second positioning machine 42 can also retract the second positioning pin 41 to its initial position.

[0059] Among them, Figure 2 The second positioning machine 42 is fixed on a side of the bidirectional slide rail structure 1 opposite to the first positioning machine 32 . For example, the second positioning machine 42 can be welded on the side of the bidirectional slide rail structure 1 .

[0060] In addition, the specific design of the second positioning pin feeding structure 4 is similar to the specific design of the first positioning pin feeding structure 3 described above, and the embodiment of the present invention will not be repeated here.

[0061] Based on the above-mentioned first positioning pin feeding structure 3 and second positioning pin feeding structure 4, it should be noted that in the process of horizontally bending the conductor, the first positioning pin feeding structure 3 and the second positioning pin feeding structure 4 push the conductor from opposite directions respectively, so that the pressure of the first positioning pin 31 on the conductor and the pressure of the second positioning pin 41 on the conductor are opposite in direction, equal in magnitude and do not act on the same straight line.

[0062] In addition, the S-bend or reverse S-bend formed after the conductor is bent needs to include two centrally symmetrical bends. Therefore, in the process of bending the conductor, the first positioning machine 32 and the second positioning machine 42 should push the first positioning pin 31 and the second positioning pin 41 respectively and simultaneously, so that the first positioning pin 31 and the second positioning pin 41 push the conductor in opposite directions at the same time, so that the conductor is horizontally bent with the midpoint of the line connecting the first positioning pin 31 and the second positioning pin 41 as the support point, and the two formed bends are centrally symmetrical with the midpoint.

[0063] (V) Structure and working principle of adjustable limit plate 5

[0064] In the embodiment of the present invention, the adjustable limit plate 5 is used to limit the distance that the first positioning machine 32 pushes the first positioning pin 31 forward, that is, in the process of pushing the first positioning pin 31 to bend the wire horizontally, the first positioning pin 31 can only be pushed to the position of the adjustable limit plate 5 at most. The adjustable limit plate 5 can be a metal plate on the upper surface perpendicular to the fixed plate 2, and the metal plate has an anti-extrusion property, that is, the metal plate is not easily deformed by the extrusion of the first positioning pin 31. In addition, the adjustable limit plate 5 is slidably connected to the fixed plate 2 and is arranged on the side opposite to the first positioning pin feeding structure 3, such as Figure 2 , the lower surface of the adjustable limiting plate 5 can contact the upper surface of the fixed plate 2.

[0065] In one possible design, a fixing piece can be designed between the adjustable limit plate 5 and the fixed plate 2. After the adjustable limit plate 5 is adjusted to an appropriate position as needed, the fixing piece can be used to fix the adjustable limit plate 5 and the fixed plate 2 together to prevent the adjustable limit plate 5 from moving during the horizontal bending of the conductor.

[0066] In a possible design, a scale can be designed at the position of the fixed plate 2 corresponding to the adjustable limit plate 5. For example, the horizontal line of the scale can be perpendicular to the adjustable limit plate 5. The scale is used to mark the relative displacement of the adjustable limit plate 5 based on the fixed plate 2. The relative displacement of the limit plate 5 can be recorded by reading the scale value. Then, based on the specific data recorded, it is more convenient for the staff to adjust the adjustable limit plate 5 until it meets the requirements. In addition, it is also more convenient to adjust the limit plate adjustment structure 6 based on the relative displacement of the adjustable limit plate 5. Of course, the relative movement distance of the adjustable limit plate 5 can also be marked in other ways. The embodiment of the present invention does not limit the marking method of the relative movement distance of the adjustable limit plate 5 and the specific position of the above-mentioned scale.

[0067] In a possible design, an adjustable fixed plate can be designed on one side of the adjustable limit plate 5 close to the first positioning pin feeding structure 3. The adjustable fixed plate can be slidably connected to the adjustable limit plate 5. The adjustable fixed plate is used to press the wire to be bent to prevent the wire from being squeezed out of the fixed plate 2 during the horizontal bending process, thereby preventing the wire from being separated from the fixed plate 2 and affecting the horizontal bending quality of the wire.

[0068] Furthermore, if Figure 2 The end of the adjustable fixed plate close to the second positioning pin feeding structure 4 can be designed to be wedge-shaped, so that when the two-way slide rail structure 1 and the fixed plate are sliding relative to each other, the wedge-shaped design can reduce the minimum distance between the adjustable fixed plate and the limit plate adjustment structure 6, that is, the wedge-shaped design can make the adjustable fixed plate and the limit plate adjustment structure 6 as close as possible.

[0069] (VI) Structure and working principle of the limit plate adjustment structure 6

[0070] In the embodiment of the present invention, the limit plate adjustment structure 6 is used to limit the distance that the second positioning machine 42 pushes the second positioning pin 41 to move forward, and is used to achieve the upper and lower bending of the wire. The limit plate adjustment structure 6 includes an adjustment body 61, a limit upper plate 62 and a limit lower plate 63, wherein, as shown in FIG. Figure 2 The adjusting body 61 is fixed on the bidirectional slide rail structure 1 and is on the same side as the first positioning pin feeding structure 3. Figure 1 As shown, the upper limit plate 62 and the lower limit plate 63 are respectively slidably connected to the adjustment body 61, and the upper limit plate 62 is above the lower limit plate 63. The adjustment body 61 can horizontally adjust the upper limit plate 62 and the lower limit plate 63 by moving up and down and extending left and right. The upper limit plate 62 is used to press the wire to be bent, and the lower limit plate 63 is used to assist the wire in bending.

[0071] In one possible design, the limiting lower plate 63 can be designed to include a horizontal plate and a vertical plate. The horizontal plate can be designed to be fixed together with the vertical plate, and the vertical plate can be slidably connected to the adjustment body 61. The vertical plate can be moved in the horizontal direction by the adjustment body 61, so that the vertical plate can be used to limit the distance that the second positioning pin 41 moves forward, that is, in the process of horizontally bending the wire, the second positioning pin 41 can only reach the position of the vertical plate at most.

[0072] Furthermore, in order to mark the relative displacement of the vertical plate in the horizontal direction, a scale can be designed at the position of the fixed plate 2 corresponding to the vertical plate. Through the scale, based on the relative displacement of the adjustable limit plate 5 recorded above, the vertical plate is moved by the same displacement, so that the two bends finally formed by the wire are symmetrical in center.

[0073] In addition, the vertical plate can be moved vertically by adjusting the distance between the horizontal plate and the fixed plate 2 through the adjusting body 61, thereby realizing the up and down bending of the wire. Specifically, the wire is placed between the upper limit plate 62 and the lower limit plate 63, and the first positioning pin 31 and the second positioning pin 41 are pushed respectively to complete the horizontal bending of the wire. Then, the horizontal plate of the lower limit plate 63 is lifted by the adjusting body 61, thereby realizing the up and down bending of the wire. Then, the wire that has been successfully bent up and down can be manually replaced.

[0074] In one possible design, a groove can be designed on the upper bottom surface of the fixed plate 2. During the horizontal bending of the wire, the horizontal plate of the limiting lower plate 63 can be placed in the groove so that the upper surface of the horizontal plate is flush with the upper surface of the fixed plate 2.

[0075] In one possible design, Figure 2 In order to better compress the wire to be bent and avoid the wire from deforming up and down during horizontal bending, Figure 2 The limiting upper plate 62 may be designed to extend a portion toward the direction of the first positioning pin feeding structure 3, and the extended portion is used to further compress the wire to be bent.

[0076] Furthermore, if Figure 2 The end of the limiting upper plate 62 close to the first positioning pin feeding structure 3 can be designed to be wedge-shaped. The wedge-shaped design is conducive to the first positioning pin 31 and the second positioning pin 41 being as close as possible, and during the horizontal bending of the wire, the multiple structures of the entire wire bending device will not hinder each other as much as possible.

[0077] Based on the above-mentioned wire bending device, a motor structure can also be designed in the device, and the motor structure can be an electric motor structure or a pneumatic motor structure, etc. The motor structure is used to provide power to the first positioning pin feeding structure 3, the second positioning pin feeding structure 4, the adjustable limit plate 5 and the limit plate adjustment structure 6, so that the first positioning machine 32, the second positioning machine 42, the adjustable limit plate 5 and the adjustment body 61 can be driven by electricity or pneumatic force, etc., which greatly saves labor.

[0078] Based on the above-mentioned conductor bending device, the conductor before the transformer winding can be bent by holding the entire conductor bending device. The specific process of conductor bending is as follows: the conductor is placed on the fixing plate 2 The guide rail 1 is on the center axis of the forehead, and the conductor is between the horizontal plates of the upper limit plate 62 and the lower limit plate 63. According to the needs, the vertical plates of the adjustable limit plate 5 and the lower limit plate 63 are adjusted, and the distance from the adjustable limit plate 5 to the conductor and the distance from the vertical plate of the lower limit plate 63 to the conductor are equal; then, according to the needs, the two-way slide rail structure 1 and the fixed plate 2 are relatively slid to adjust the distance between the first positioning pin 31 and the second positioning pin 41; then, power is provided to the adjusting body 61, so that the adjusting body 61 drives the upper limit plate 62 to move downward until the upper limit plate 62 presses the conductor; finally, power is provided to the first positioning machine 32 and the second positioning machine 42, so that the first positioning machine 32 and the second positioning machine 42 respectively push the conductor to the adjustable limit plate 5 and the vertical plate of the lower limit plate 63 at the same time to complete the horizontal bending of the conductor.

[0079] Furthermore, without operating other structures, only power is provided to the adjusting body 61, so that the adjusting body 61 drives the upper limiting plate 62 to move upward, providing a certain space for the up and down bending of the wire; then, power is continued to be provided to the adjusting body 61, so that the adjusting body 61 drives the horizontal plate of the lower limiting plate 63 to move upward appropriately, thereby realizing the up and down bending of the wire.

[0080] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present disclosure, and will not be described in detail here.

[0081] The above is only for the purpose of facilitating those skilled in the art to understand the technical solution of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
