Description

Technical Field

[0001] This utility model belongs to the field of aluminum wire straightening technology, specifically, it relates to a high-precision aluminum wire stretching and straightening device. Background Technology

[0002] In the field of metal wire processing, aluminum wire is widely used in electronic components, power transmission, aerospace, and other fields due to its excellent conductivity, lightweight, and corrosion resistance. However, aluminum wire is prone to plastic deformation such as bending and twisting during drawing, winding, or transportation, which affects its mechanical properties and subsequent processing accuracy. Therefore, aluminum wire usually needs to be straightened before being put into use to ensure that its straightness and dimensional accuracy meet the requirements.

[0003] Traditional aluminum wire straightening methods mainly include mechanical roller straightening, hydraulic tension straightening, and heat treatment straightening. However, these methods have the following technical limitations;

[0004] Currently, mechanical roll straightening relies on multiple sets of straightening rollers to repeatedly bend and straighten aluminum wires, which can easily cause indentations or scratches on the surface of the aluminum wires, affecting surface quality. For high-precision fine aluminum wires, roll straightening may lead to excessive deformation or breakage, making it difficult to achieve uniform straightening. Hydraulic cylinders or pneumatic cylinders are used to provide tension, but the system response is slow and affected by fluctuations in the pressure of the medium (oil / gas). The tension control accuracy is low, the equipment structure is complex, and the maintenance cost is high, making it difficult to adapt to the needs of high-frequency, small-batch flexible production.

[0005] To address the aforementioned issues, this application proposes a high-precision aluminum wire stretching and straightening device. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a high-precision aluminum wire stretching and straightening device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-precision aluminum wire stretching and straightening device includes a fixed cylinder, a heating coil provided on the inner wall of the fixed cylinder, and an adjusting resistor fixedly installed at the bottom of the fixed cylinder, the adjusting resistor being connected to the heating coil.

[0009] The straightening and stretching mechanism includes two drive coils, which are disposed on the inner wall of the fixed cylinder and connected to an adjusting resistor.

[0010] The clamping mechanism includes two base plates, which are mounted on both sides of a fixed cylinder and are connected to two drive coils. A lead screw is rotatably connected to the top of the fixed cylinder, and a pressure rod is threaded onto the lead screw. The pressure rod cooperates with the two base plates.

[0011] Preferably, the straightening and stretching mechanism further includes two magnetic rings, and two movable rings are slidably connected on the inner wall of the fixed cylinder. The magnetic rings are fixedly connected to the corresponding movable rings, and the magnetic rings cooperate with the corresponding drive coils. Four push rods are fixedly installed on the side of the two movable rings that are far apart from each other, and the four push rods on the same side are fixedly connected to the corresponding base plate.

[0012] The magnetic ring, through its interaction with the drive coil, can be moved under the influence of the magnetic field within the drive coil. The magnetic ring pushes the two substrates away from each other via a push rod, and is then stretched and straightened by the aluminum wire on the clamping mechanism.

[0013] Preferably, the clamping mechanism further includes two drive plates, which are slidably mounted on one side of the base plate, and clamping rods are fixedly mounted on the sides of the two drive plates that are close to each other, and the two clamping rods cooperate with each other.

[0014] The two drive plates move closer together, which in turn causes the two clamping rods to move closer together. Both clamping rods have concave openings on the side where they move closer together, and the two clamping rods clamp and fix the aluminum wire through the concave openings.

[0015] Preferably, four positioning blocks are fixedly installed on one side of the substrate, and the same moving rod is slidably connected between each pair of the four positioning blocks. The moving rod is drivenly connected to the corresponding drive plate. The top ends of the two moving rods on the same side are fixedly installed with the same connecting rod, and the top of the connecting rod is fixedly installed with a fixing block. The two fixing blocks are slidably connected to the pressure rod.

[0016] The movable rod is positioned by sliding connection with two corresponding positioning blocks. At the same time, the pressure rod is laterally slidingly connected with two fixed blocks, which can press the two fixed blocks to move downward. The fixed blocks drive the two movable rods to move downward through the connecting rod.

[0017] Preferably, a convex shaft is fixedly installed on one side of the moving rod, and a slanted groove is fixedly installed on one side of the drive plate, with the slanted groove slidably connected to the corresponding convex shaft.

[0018] The movable rod is slidably connected to the inclined groove via a convex shaft, and the drive plate is slidably connected to the base plate in the lateral direction, thereby driving the two drive plates to move closer to each other, which in turn drives the two clamping rods to move closer to each other.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] Composite design of electromagnetic drive and mechanical transmission

[0021] Non-contact power transmission is achieved by using the electromagnetic interaction between the drive coil and the magnetic ring. The moving ring and push rod are directly driven by the magnetic field, avoiding the complexity of traditional hydraulic or pneumatic systems. It has a faster response and no mechanical wear. The linkage design between the magnetic ring and the drive coil allows for precise control of the tensile force by adjusting the current, achieving high-precision straightening.

[0022] Integrated heating and stretching coordinated control

[0023] The heating coil is built into the inner wall of the fixed cylinder, directly heating and softening the aluminum wire locally. This is done simultaneously with the stretching action, reducing the material's yield strength and stress concentration during the stretching process. Adjusting the resistance controls the power of both the heating coil and the drive coil, achieving dynamic matching between temperature and tension, and preventing straightening failure caused by overheating or insufficient tension.

[0024] Lever-inclined plane composite transmission of clamping mechanism

[0025] The clamping mechanism presses down on the fixed block with a pressure rod, which drives the connecting rod and the moving rod to move. The vertical motion is converted into horizontal clamping force by using the inclined surface structure of the convex shaft and the inclined groove. The structure is compact and the clamping force is uniform. The concave opening design of the clamping rod increases the contact area to prevent damage to the aluminum wire surface, while also adapting to different wire diameters.

[0026] Bidirectional stretching and dynamic adjustment capabilities

[0027] Two drive coils are symmetrically arranged and the substrate is pushed to separate in both directions synchronously through a magnetic ring, so as to achieve bidirectional uniform stretching of aluminum wire, avoid bending residue caused by unilateral stress, and adjust the heating temperature and magnetic field strength in real time by adjusting the resistance, so as to adapt to aluminum wires of different materials or diameters and improve process adaptability.

[0028] This invention achieves efficient and high-precision straightening of aluminum wires through the synergistic effect of electromagnetic drive and thermal softening, and has the advantages of fast response speed, high controllability and low energy consumption. It is especially suitable for processing aluminum wires for precision electronic components. Attached Figure Description

The four push rods 44 on the same side are fixedly connected to the corresponding base plate 51. The magnetic rings 43 can be pushed to move under the action of the magnetic field in the drive coil 41 by cooperating with the drive coil 41. The magnetic rings 43 push the two base plates 51 away from each other through the push rods 44, and then stretch and straighten through the aluminum wire on the clamping mechanism 5.

[0040] Reference Figure 4The clamping mechanism 5 also includes two drive plates 52, which are slidably mounted on one side of the base plate 51. Clamping rods 53 are fixedly mounted on the sides of the two drive plates 52 that are close to each other. The clamping rods 53 cooperate with each other. Four positioning blocks 54 are fixedly mounted on one side of the base plate 51. A single moving rod 55 is slidably connected between each pair of the four positioning blocks 54. The moving rod 55 is drive-connected to the corresponding drive plate 52. A single connecting rod 58 is fixedly mounted at the top of the two moving rods 55 on the same side.

The slanted groove 57 is slidably connected to the corresponding convex shaft 56. The mechanism is driven by the moving rod 55. The rod 55 is slidably connected to the two corresponding positioning blocks 54, thereby positioning the moving rod 55. At the same time, the pressure rod 7 is slidably connected to the two fixed blocks 59, thereby pressing the two fixed blocks 59 to move downward.

The moving rods 55 are slidably connected to the inclined groove 57 through the convex shaft 56, and the drive plate 52 is slidably connected to the base plate 51, thereby driving the two drive plates 52 to move closer to each other, and then driving the two clamping rods 53 to move closer to each other.

[0041] Working principle: During operation, the aluminum wire is conveyed and moved through both ends of the fixed cylinder 1. When stretching and straightening are required, the lead screw 6 is rotated. The lead screw 6 is threadedly connected to the pressure rod 7, which drives the pressure rod 7 to move downward. The pressure rod 7 is laterally slidably connected to two fixed blocks 59, which presses the two fixed blocks 59 downward. The fixed blocks 59 drive two moving rods 55 downward through the connecting rod 58. The moving rods 55 are slidably connected to the inclined groove 57 through the convex shaft 56, and the drive plate 52 is laterally slidably connected to the base plate 51, which drives the two drive plates 52 to move closer to each other, and then drives the two clamping rods 53 to move closer to each other. The two clamping rods 53 are both set with concave openings on the side where they are close to each other. The two clamping rods 53 clamp and fix the aluminum wire through the concave openings. Then, the aluminum wire is clamped and fixed. Heating coil 2 heats the aluminum wire, softening it. Simultaneously, magnetic ring 43, in cooperation with drive coil 41, moves under the influence of the magnetic field within drive coil 41. Magnetic ring 43 pushes the two substrates 51 away from each other via push rod 44, thus stretching and straightening the aluminum wire on clamping mechanism 5. When adjusting the stretching and straightening precision, the power of heating coil 2 and drive coil 41 is adjusted by adjusting resistor 3. Increasing the power of heating coil 2 increases the magnetic field strength, thereby adjusting the temperature of the aluminum wire and the degree of softening, making stretching easier. Increasing the power of drive coil 41 increases the magnetic field strength, adjusting the force acting on magnetic ring 43, and thus adjusting the pulling force of substrate 51 on the aluminum wire, enabling precise straightening of the aluminum wire.
