Description

Technical Field

[0001] The present invention relates to the field of copper wire straightening, and in particular to a straightening device for copper wire production. Background Art

[0002] Copper wire is widely used in many fields due to its excellent electrical conductivity, thermal conductivity, ductility and cost-effectiveness, especially in the fields of power transmission and electronic communications, for transmission lines, circuit board connections and lead frames. Among them, flat copper wire is a copper conductor with a special cross-section. Its cross-section is rectangular. During production and application, it is often bent due to processing stress, transportation and improper storage. In order to ensure the electrical performance and mechanical strength of the copper wire, the bent copper wire needs to be straightened. Due to the shape of the flat copper wire, it needs to be straightened in the horizontal and vertical directions respectively.

[0003] However, the existing straightening device is not convenient for adjusting the extrusion degree, resulting in incomplete straightening of the copper wire. When conveying long copper wire, the copper wire is prone to additional bending due to its own gravity, and is also prone to tilting during horizontal extrusion straightening, resulting in poor straightening effect. Summary of the Invention

[0004] In order to overcome the shortcomings of the background technology, the present invention provides a straightening device for copper wire production, which can straighten the copper wire more thoroughly, is convenient for tensioning the copper wire, and is not likely to cause the copper wire to tilt horizontally.

[0008] Furthermore, the anti-slip mechanism includes two electric push rods, both of which are fixedly connected to the base plate, a speed sensor is provided on the base plate, the speed sensor is used to measure the speed of the active roller and the driven roller, the speed sensor is connected to the electric push rod through a wire, each of the electric push rods is fixedly connected to a limit plate, each of the limit plates is slidably connected to a movable support rod, two guide plates are fixedly connected to the base plate, a guide groove is provided on the guide plate, the lower part of the movable support rod is located in the guide groove on the guide plate, the upper part of each of the movable support rods is slidably connected to an extrusion plate, and a connecting spring is connected between the extrusion plate and the movable support rod.

[0009] Furthermore, it also includes an anti-bending mechanism, which is arranged on the base plate and is used to prevent the copper wire from bending due to its own gravity. The anti-bending mechanism includes a multi-stage telescopic rod, which is fixedly connected to the base plate, and a support frame is fixedly connected to the telescopic axis of the multi-stage telescopic rod. A handle is provided on one side of the support frame, and two side wheels are rotatably connected to the support frame. Two pressure wheels are rotatably connected to the support frame, and each pressure wheel is fixedly connected to a friction wheel. Two friction blocks are fixedly connected to the support frame, and the friction blocks are in contact with the friction wheels.

[0010] Furthermore, it also includes a leveling mechanism, which is arranged on the base plate and is used to maintain the horizontal state of the copper wire. The leveling mechanism includes two vertical plates, both of which are fixedly connected to the base plate, and both of which are slidably connected to two push rods, a return spring is connected between the push rods and the vertical plates, and each of the push rods is rotatably connected to a contact rotating rod, two guide frames are fixedly connected to the base plate, two inclined plane frames 1 are fixedly connected to the base plate, and two inclined plane frames 2 are fixedly connected to the adjustment frame.

[0011] The beneficial effects are: 1. By shaking the first and second shaking wheels respectively, the degree of squeezing of the copper wire in the vertical and horizontal directions can be adjusted respectively, so that the copper wire that is not completely straightened can be further straightened multiple times more conveniently, making the copper wire straightened more thoroughly.

[0012] 2. During the transmission process, the copper wire will drive the pressure wheel to rotate through friction, and then drive the friction wheel to rotate together. The friction wheel will be subject to resistance from the friction block, so that the pressure wheel will encounter a certain resistance when rotating. In this way, when the copper wire starts to be transmitted, it will pull the multi-stage telescopic rod to shrink and drive the pressure wheel and the support frame to move. At the same time, the copper wire will also be subject to resistance in the opposite direction of transmission during transmission, so that the copper wire between the pressure wheel and the active roller is in a certain degree of tension. In this way, the copper wire that has not been straightened is not easy to produce additional bending due to its own gravity, making the copper wire easier to be straightened.

[0013] 3. When performing horizontal straightening, the copper wire will also pass through the guide frame and the two contact rotating rods. The contact rotating rods and the guide frame will press the upper and lower surfaces of the copper wire. This will prevent the copper wire from tilting when it is squeezed during horizontal straightening, thereby ensuring that the copper wire straightening can proceed normally. At the same time, the second bevel frame and the first bevel frame can ensure that the copper wire is guided in the transmission direction when it passes through the horizontal moving wheel and the horizontal fixed wheel, so that the copper wire is not easily hit.

[0025] The vertical straightening mechanism includes a support plate 51, which is fixedly connected to the base plate 2, and a rocker 52 is rotatably connected to the support plate 51, and a bevel gear 53 is fixedly connected to the rocker 52. A movable frame 54 is slidably connected between the two round rods 21, and a threaded rotating rod 55 is rotatably connected to the support plate 51. The upper part of the threaded rotating rod 55 is threadedly connected to the movable frame 54, and a bevel gear 2 56 is fixedly connected to the threaded rotating rod 55. The bevel gear 2 56 is meshed with the bevel gear 1 53. Two vertical movable wheels 57 are rotatably connected to the movable frame 54, and each of the curved frames 22 is rotatably connected to a vertical fixed wheel 58.

[0026] The horizontal straightening mechanism includes a limiting frame 61, an adjusting frame 62 is slidably connected to the limiting frame 61, a rotating screw 63 is rotatably connected to the limiting frame 61, the rotating screw 63 is threadedly connected to the adjusting frame 62, a rocker wheel 2 64 is fixedly connected to the rotating screw 63, one side of the adjusting frame 62 is rotatably connected to two horizontal moving wheels 65, and three horizontal fixed wheels 66 are rotatably connected to the base plate 2.

[0027] The anti-slip mechanism includes two electric push rods 71, both of which are fixedly connected to the base plate 2. A speed sensor 72 is provided on the base plate 2. The speed sensor 72 is used to measure the speed of the active roller 33 and the driven roller 36. The speed sensor 72 is connected to the electric push rod 71 through a wire. Each of the electric push rods 71 ​​is fixedly connected to a limit plate 73, and each of the limit plates 73 is slidably connected to a movable support rod 74. Two guide plates 75 are fixedly connected to the base plate 2, and a guide groove is provided on the guide plate 75. The lower part of the movable support rod 74 is located in the guide groove on the guide plate 75. The upper part of each movable support rod 74 is slidably connected to an extrusion plate 76, and a connecting spring 77 is connected between the extrusion plate 76 and the movable support rod 74.

[0028] The flat-angle copper wire is a type of copper wire with a rectangular cross-section. When the flat-angle copper wire is bent, it will deform in the horizontal and vertical directions. Therefore, in the actual copper wire straightening process, the copper wire needs to be straightened in two directions. First, the drive motor 31 is started, and the drive motor 31 drives the active roller 33 to rotate. Then the copper wire is placed horizontally between the active roller 33 and the driven roller 36, and the copper wire is located between the two extrusion plates 76. The rotating active roller 33 and the driven roller 36 squeeze the copper wire and convey the copper wire. The copper wire passes through the vertical fixed wheel 58 and the vertical movable wheel 57 in turn. After the vertical extrusion of the copper wire, the vertical bending of the copper wire is corrected to a certain extent, and then the copper wire continues to move horizontally, and passes through the horizontal fixed wheel 66 and the horizontal moving wheel 65 in succession. The horizontal fixed wheel 66 and the horizontal moving wheel 65 squeeze the copper wire in the horizontal direction, so that the horizontal bending of the copper wire is corrected to a certain extent. In this way, the copper wire coming out of the discharge roller 4 is straightened once. If the copper wire still has a certain bending, it can be driven by shaking the rocking wheel 1 52 and the rocking wheel 2 64 respectively to drive the threaded rotating rod 55 and the rotating screw 63 to rotate respectively, and then drive the vertical moving wheel 57 to move vertically and the horizontal moving wheel 65 to move horizontally respectively. The vertical moving wheel 57 can move vertically. Adjust the degree of squeezing the copper wire in the vertical direction. The horizontal movement of the horizontal moving wheel 65 can adjust the degree of squeezing the copper wire in the horizontal direction. In this way, the copper wire that is not completely straightened can be further straightened multiple times more conveniently, so that the copper wire is straightened more thoroughly. At the same time, during the transmission of the copper wire, due to the smooth surface of the copper wire, the copper wire is prone to slipping between the copper wire and the active roller 33 during the transmission process, so that the copper wire is no longer transmitted. When slipping occurs, the active roller 33 continues to rotate, but the driven roller 36 no longer rotates, and a difference in speed occurs between the active roller 33 and the driven roller 36. Then the speed sensor 72 is triggered, and then the electric push rod 71 is controlled to start , the electric push rod 71 reciprocates and extends. The extension of the electric push rod 71 will drive the limit plate 73 and the moving support rod 74 to move horizontally in the direction of copper wire transmission. Then, under the guidance of the guide plate 75, the two moving support rods 74 will move horizontally for a distance in the direction of approaching each other. The horizontal movement of the moving support rod 74 in the direction of approaching each other will drive the two squeezing plates 76 to move horizontally in the direction of approaching each other, and then squeeze and clamp the two sides of the middle copper wire. At the same time, the squeezing plate 76 moves horizontally in the direction of copper wire transmission, so that the squeezing plate 76 can clamp the copper wire and push the copper wire to move, thereby removing the position where the copper wire slips, allowing the copper wire to continue to be transmitted.

[0029] Example 2 On the basis of Example 1, Figure 5-6As shown, an anti-bending mechanism is also included, which is arranged on the base plate 2. The anti-bending mechanism is used to prevent the copper wire from bending due to its own gravity. The anti-bending mechanism includes a multi-stage telescopic rod 81, which is fixedly connected to the base plate 2. A support frame 82 is fixedly connected to the telescopic axis of the multi-stage telescopic rod 81, and a handle 83 is provided on one side of the support frame 82. Two side wheels 84 are rotatably connected to the support frame 82, and two pressure wheels 85 are rotatably connected to the support frame 82. Each pressure wheel 85 is fixedly connected to a friction wheel 86, and two friction blocks 87 are fixedly connected to the support frame 82, and the friction blocks 87 are in contact with the friction wheel 86.

[0030] First, pass one end of the copper wire through the two pressure rollers 85, then pull the handle 83 to extend the multi-stage telescopic rod 81, and then place the copper wire between the active roller 33 and the driven roller 36 for transmission. During the transmission process, the copper wire will drive the pressure roller 85 to rotate through friction, and then drive the friction wheel 86 to rotate together. The friction wheel 86 will be resisted by the friction block 87, so that the pressure roller 85 will encounter a certain resistance when rotating. In this way, when the copper wire starts to be transmitted, it will pull the multi-stage telescopic rod 81 to contract and drive the pressure roller 85 and the support frame 82 to move. At the same time, it will also cause the copper wire to encounter resistance in the opposite direction of transmission during transmission, so that the copper wire between the pressure roller 85 and the active roller 33 is in a certain degree of tension. In this way, the copper wire that has not been straightened is not easy to produce additional bending due to its own gravity, thereby making the copper wire easier to be straightened.

[0031] Example 3 On the basis of Example 2, Figure 7-8 As shown, a leveling mechanism is also included, which is arranged on the base plate 2. The leveling mechanism is used to maintain the horizontal state of the copper wire. The leveling mechanism includes two vertical plates 91, and the two vertical plates 91 are fixedly connected to the base plate 2. Two top rods 92 are slidably connected to the two vertical plates 91, and a return spring 93 is connected between the top rod 92 and the vertical plate 91. A contact rotating rod 94 is rotatably connected to each of the top rods 92. Two guide frames 95 are fixedly connected to the base plate 2, two inclined plane frames 96 are fixedly connected to the base plate 2, and two inclined plane frames 97 are fixedly connected to the adjustment frame 62.

[0032] After the copper wire has been straightened in the vertical direction, it continues to be conveyed. When straightening in the horizontal direction, the copper wire will also pass between the guide frame 95 and the two contact rotating rods 94. The contact rotating rods 94 and the guide frame 95 will press the upper and lower surfaces of the copper wire. In this way, the copper wire is not easy to tilt when it is squeezed during horizontal straightening, thereby allowing the copper wire straightening to proceed normally. At the same time, the inclined plane frame 2 97 and the inclined plane frame 1 96 can ensure that the copper wire is guided in the conveying direction when passing through the horizontal moving wheel 65 and the horizontal fixed wheel 66, so that the copper wire is not easily hit.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
