Detailed Implementation

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] Example 1:

[0034] like Figures 1-11As shown, a welding wire heating, flattening, and straightening device includes a support base 1 for support, a straightening structure 2 for straightening, and a flattening structure 3 for flattening the welding wire. Both the straightening structure 2 and the flattening structure 3 are mounted on the support base 1. It also includes a heating structure 4, which is fixedly mounted on the support base 1. The heating structure 4 is located at one end of the support column where the copper wire is fed in; the side of the heating structure 4 from which the copper wire is fed faces the flattening structure 3 and the straightening structure 2. The heating structure 4 includes an electric heating wire 41 for heating and a heating housing 42. The heating housing 42 is tubular, with openings at both ends for the copper wire to pass through and exit. The electric heating wire 41 is spirally arranged inside the heating housing 42. The heating structure 4 heats the passing copper wire, raising its temperature and softening its material, improving its plasticity, and effectively preventing burrs during the flattening process of the flattening structure 3, thus improving product quality.

[0035] The heating wire 41 is embedded in the inner wall of the heating housing 42, with both ends extending outwards to connect to external electrical equipment. In this example, the heating wire 41 is made of an iron-chromium-aluminum heating alloy or a nickel-chromium heating alloy. These two alloys generate heat when energized, which is used to heat the copper wire passing through them. It should be noted that, to reduce heat loss, end caps 43 are provided at both ends of the heating housing 42. Each end cap 43 has a through hole in the middle for inserting the copper wire. The end caps 43 are integrally formed with the heating housing 42. In this example, the through hole on the end caps 43 is chamfered to facilitate the insertion and exit of the copper wire.

[0036] The flattening structure 3 is located between the straightening structure 2 and the heating structure 4. Because the copper wire is subjected to stronger force when it is flattened, it is more likely to break or develop burrs. Therefore, after the copper wire passes through the heating structure 4, it first passes through the flattening structure 3 to adjust its shape, and then it is straightened more gently.

[0037] The flattening structure 3 includes two sets of flattening components 31, which are symmetrically arranged to flatten the copper wire passing between them into a predetermined shape. Each flattening component 31 includes a flattening base 32, a connecting rod 33, a clamping plate 34, and a flattening wheel 35. The flattening base 32 is slidably disposed in a sliding hole 11 on the support base 1. The sliding direction of the flattening base 32 in the sliding hole 11 is perpendicular to the movement direction of the copper wire, which facilitates adjustment of the distance between the two flattening components 31 to accommodate copper wires of different sizes and the flattening wheel 35. The connecting rod 33 is fixedly disposed above the flattening base 32. The clamping plate 34 is sleeved on the connecting rod 33 and is also fixedly connected to the flattening base 32. The clamping plate 34 cooperates with the flattening base 32 to clamp the edge of the sliding hole 11 on the support base 1 for fixation. The flattening wheel 35 is rotatably disposed on the connecting rod 33, and the flattening wheel 35 corresponds to the copper wire delivered by the heating structure 4. In this example, a detachable screw 36 is provided above the flattening wheel 35. The screw 36 is fixedly connected to the end of the connecting rod 33, which facilitates the replacement of the flattening wheel 35 and achieves the flattening effect of copper wires of different shapes and sizes. The connecting rod 33 is also provided with a support platform 37 corresponding to the flattening wheel 35. The screw 36 and the support platform 37 cooperate to clamp the flattening wheel 35 on the connecting rod 33. The height of the support platform 37 on the connecting rod 33 corresponds to the height of the copper wire delivered by the heating structure 4, so that the copper wire passing through the heating structure 4 can be fed straight into the flattening wheel 35 on the support platform 37.

[0038] The flattened base 32 includes a base plate 321 and a sliding plate 322; both the base plate 321 and the sliding plate 322 are waist-shaped plates with the same length, and the width of the base plate 321 is greater than the width of the sliding plate 322; the clamping plate 34 is also waist-shaped, and the width of the clamping plate 34 is greater than the width of the sliding plate 322; the sliding hole 11 is configured with a corresponding three-layer structure, the upper layer of the sliding hole 11 is a waist-shaped hole corresponding to the width of the clamping plate 34, the middle layer of the sliding hole 11 is a waist-shaped hole corresponding to the width of the sliding plate 322, and the bottom layer of the sliding hole 11 is a waist-shaped hole corresponding to the width of the base plate 321; the clamping plate 34 and the base plate 321 of the flattened base 32 clamp the middle layer of the sliding hole 11 to fix the flattened part 31, while the cooperation between the sliding plate 322 and the middle layer of the sliding hole 11 can ensure that the flattened base 32 slides directionally within the sliding hole 11 and prevents it from rotating. In this example, the edge of the sliding hole 11 of the support base 1 is also provided with a first tooth structure 12 for locking the clamping plate 34, and the side of the clamping plate 34 facing the flattened base 32 is provided with a second tooth structure 341 corresponding to the first tooth structure 12; when the clamping plate 34 is fixedly clamped to the flattened base 32, the first tooth structure 12 and the second tooth structure 341 engage, so that the sliding part in the sliding hole 11 achieves a better fixing effect. In this example, both the first tooth structure and the second tooth structure 341 are triangular teeth.

[0039] The straightening structure 2 includes a longitudinal straightening component 21 and a transverse straightening component 22. The longitudinal straightening component 21 is used to press the copper wire vertically, and the transverse straightening component 22 is used to press the copper wire horizontally. The longitudinal straightening component 21 includes a first base 211, a first slide rail 212, a first slider 214, a first adjusting rod 216, a first elastic element 217, a first fixed wheel 218, and a first sliding wheel 219. The first base 211 is fixedly mounted above the support base 1. The first slide rail 212 is fixedly mounted on the first base 211, and the first slider 214 is slidably mounted on the first slide rail 212. A first elastic element 217 is also provided between the first slider 214 and the first base 211. In this example, the first elastic element 217... The spring-loaded component 217 helps the first slider 214 return to its original position. The end of the first adjusting rod 216 is connected to the first slider 214 and also to the first slide rail 212. This adjustment rod is used to adjust the positional relationship between the first slider 214 and the first slide rail 212, thereby controlling the distance between the first sliding wheel 219 and the first fixed wheel 218 to accommodate copper wires of different sizes and shapes. The fixed wheel is rotatably mounted on the first base 211, and the first sliding wheel 219 is rotatably mounted on the first slider 214. The sides of the first slide rail 212 are provided with trapezoidal grooves 213 that are wider at the bottom and narrower at the top. The sides of the first slider 214 are provided with locking blocks 215 corresponding to the trapezoidal grooves 213. This makes the sliding process of the first slider 214 within the first slide rail 212 more stable and prevents left and right deviation. In this example, the first base 211 is provided with three first fixed wheels 218, and a first slide rail 212 is provided between two adjacent first fixed wheels 218. There are two first slide rails 212 in the longitudinal straightening member 21, corresponding to two first sliders 214 and first sliding wheels 219. The first fixed wheels 218 and the first sliding wheels 219 are arranged along an "S"-shaped curve.

[0040] The horizontal straightening component 22 has a similar structure to the vertical straightening component. The horizontal straightening component 22 includes a second base 221, a second slide rail 222, a second slider 223, a second adjusting rod 224, a second elastic element 225, a second fixed wheel 226, and a second sliding wheel 227. The second base 221 is fixedly mounted above the support base 1. The second slide rail 222 is fixedly mounted on the second base 221, and the second slider 223 is slidably mounted on the second slide rail 222. A second elastic element 225 is also provided between the second slider 223 and the second base 221. The end of the second adjusting rod 224 is connected to the second slider 223, and the second adjusting rod 224 is also connected to the second slide rail 222 to adjust the positional relationship between the second slider 223 and the second slide rail 222. The fixed wheel is rotatably mounted on the second base 221, and the second sliding wheel 227 is rotatably mounted on the second slider 223. The second fixed wheel 226 and the second sliding wheel 227 are arranged along an "S"-shaped curve. It should be noted that a pad 228 for raising the horizontal straightening component 22 is also provided between the horizontal straightening component 22 and the support base 1. The height of the horizontal straightening component 22 is controlled by the pad 228 to correspond to the height of the vertical straightening component 21.

[0041] During implementation, the heating structure 4 is set to heat the copper wire to be flattened, softening the material of the copper wire, making it easier to flatten in the flattening structure 3, and reducing the possibility of breakage and burrs; the structure of the sliding hole 11, in conjunction with the first tooth structure 12 and the second tooth structure 341, achieves relatively stable fixation of the flattening part 31, ensuring the shape stability of the flattened copper wire; the horizontal straightening part 22 and the vertical straightening part 21 are set to adjust the flattened copper wire in multiple directions, ensuring the quality of the copper wire.

Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model.
