Description

Technical Field

[0001] This utility model belongs to the field of copper-clad aluminum wire straightening technology, specifically relating to a copper-clad aluminum wire straightening device before cutting. Background Technology

[0002] Copper-clad aluminum wire is a bimetallic composite conductor with an aluminum core and an outer copper layer. It combines the excellent conductivity of copper with the lightweight properties of aluminum, making it suitable for applications requiring weight reduction, such as transformer and motor windings. Due to the combination of "excellent conductivity of copper + lightweight properties of aluminum", copper-clad aluminum wire is widely used in fields such as electronic communications and automotive wiring harnesses. When cutting the wire to the required length, a straightening device is needed to straighten the wire. Incomplete straightening will lead to deviations in the length of the cut wire, affecting the assembly effect of the wiring harness.

[0003] A search revealed Chinese patent CN219253959U, which discloses a wire and cable straightening device. The device includes a frame with two sets of wire feeding assemblies spaced horizontally on the frame. These assemblies are used for horizontally conveying wires and cables. This invention achieves automatic cable feeding by employing these assemblies, and the two sets of assemblies ensure consistent tension before and after the cable straightening components, guaranteeing a straightening effect. However, it still has the following drawbacks: the straightening power is achieved through a winding mechanism, which, if applied before a cutting device, makes it inconvenient to directly feed the straightened wire to the cutting device, affecting work efficiency. Furthermore, it is not suitable for straightening wires of different diameters. Therefore, a copper-clad aluminum wire straightening device before cutting is proposed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This utility model provides a straightening device before cutting copper-clad aluminum wire, including a support base plate 1. The top of the support base plate 1 is provided with front and rear limiting mechanisms 2, upper and lower limiting mechanisms 3, straightening drive mechanism 4, and conveying and fixing mechanism 5 from left to right.

[0025] The front and rear limiting mechanism 2, the upper and lower limiting mechanism 3, and the conveying and fixing mechanism 5 all include an arched frame 6 fixed to the top of the supporting base plate 1. A fixed guide roller 7 is fixedly connected to the middle of the arched frame 6. A threaded rod 8 is inserted into one side of the arched frame 6. A movable frame 10 is rotatably connected to one end of the threaded rod 8. A movable guide roller 13 is rotatably connected to the middle of the movable frame 10. A second motor 24 is fixedly connected to one side of the first limiting slider 12 in the middle of the conveying and fixing mechanism 5.

[0026] The movable frame 10 is symmetrically fixedly connected to the two sides of the first limiting slider 12. The arched frame 6 is symmetrically opened with limiting grooves 11 on both sides. The first limiting slider 12 is set in the middle of the limiting groove 11. The output end of the second motor 24 is fixedly connected to one end of the movable guide roller 13. The threaded rod 8 is threadedly connected to the arched frame 6. One end of the threaded rod 8 is fixedly connected to the turntable 9. The movable guide roller 13 and fixed guide roller 7 in the middle of the front and rear limiting mechanism 2 are perpendicular to the movable guide roller 13 and fixed guide roller 7 in the middle of the upper and lower limiting mechanism 3.

[0027] In this embodiment, rotating the turntable 9 controls the threaded rod 8 to drive the movable frame 10, causing the movable guide roller 13 to move towards the fixed guide roller 7. The first limiting slider 12 slides inside the limiting groove 11, improving the stability of the movable frame 10's movement. The cooperation between the movable guide roller 13 and the fixed guide roller 7 can squeeze and limit the wire passing between the movable guide roller 13 and the fixed guide roller 7. The front and rear limiting mechanisms 2 and the upper and lower limiting mechanisms 3 achieve the upper and lower and front and rear limits of the wire. The second motor 24 in the middle of the conveying and fixing mechanism 5 starts the movable guide roller 13 to rotate, and the wire can be conveyed to the cutting equipment through the conveying and fixing mechanism 5 for convenient feeding.

[0028] The straightening drive mechanism 4 includes a support plate 14 fixed to the top of the support base plate 1. A limiting frame 15 and a first motor 22 are fixedly connected to adjacent sides of the top of the support plate 14. A second limiting slider 18 is provided in the middle of the limiting frame 15. A rod 19 is inserted in the middle of the second limiting slider 18. A guide roller 20 is sleeved on one end of the rod 19. A connecting rod 21 is rotatably connected to one side of the second limiting slider 18. A rotating rod 23 is fixedly connected to the output end of the first motor 22.

[0029] A guide rod 16 is fixedly connected to the bottom of the support plate 14 on the side away from the first motor 22. One end of the guide rod 16 is fixedly connected to a limit plate 17. The cross-sectional shape of the second limit slider 18 is set to "H". The guide roller 20 is located on the side of the second limit slider 18 close to the guide rod 16. The rotating rod 23 is set on the side of the support plate 14 close to the guide rod 16. One end of the rotating rod 23 is rotatably connected to one end of the connecting rod 21.

[0030] In this embodiment, by starting the first motor 22 to control the rotating rod 23 to push the connecting rod 21, the second limiting slider 18 can be controlled to slide inside the limiting frame 15, thereby driving the insertion rod 19 to control the guide roller 20 to move towards one end of the conveying and fixing mechanism 5. This can move the end of the wire close to the front and rear limiting mechanisms 2 and the upper and lower limiting mechanisms 3 towards the straightening drive mechanism 4 to pull the wire and cooperate with the front and rear limiting mechanisms 2 and the upper and lower limiting mechanisms 3 to achieve the straightening effect.

[0031] When the first motor 22 pulls the connecting rod 21 in sequence, the guide roller 20 moves to one side of the forward and backward limiting mechanism 2. At this time, the wire on one side of the guide roller 20 will loosen, which will not affect the normal conveying of the wire by the conveying fixing mechanism 5, and facilitates continuous straightening and conveying of the wire.

[0032] It is worth noting that the second motor 24 is existing technology and will not be elaborated on further. The surfaces of the movable guide roller 13 and the fixed guide roller 7 in the middle of the conveying and fixing mechanism 5 are both provided with anti-slip teeth.

[0033] It should be noted that in this application, the motor is a servo motor with an encoder, and the number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0034] It should be noted that: In this application, an annular groove is provided axially on the inner wall of the threaded hole, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod 8 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0035] The working principle of this utility model is as follows: When in use, the wire passes between the movable guide roller 13 and the fixed guide roller 7 in the middle of the front and rear limiting mechanism 2 and the upper and lower limiting mechanism 3, and then is attached to the top of the guide roller 20. It also extends into the middle of the fixed guide roller 7 and the movable guide roller 13 in the middle of the conveying fixing mechanism 5 through the bottom of the guide rod 16.

[0036] Rotating the turntable 9 controls the movable guide roller 13 to cooperate with the fixed guide roller 7, thereby achieving the clamping and limiting of the wire;

[0037] The first motor 22 is started to control the guide roller 20 to move back and forth on one side of the limiting frame 15 to pull the end of the wire near the upper and lower limiting mechanism 3. When the wire is slack, the second motor 24 is started to control the movable guide roller 13 and the fixed guide roller 7 in the middle of the conveying and fixing mechanism 5 to convey the slack wire, which facilitates continuous pulling of the wire.

[0038] When the wire is pulled, the front and rear limit mechanisms 2 and the upper and lower limit mechanisms 3 can straighten the wire.

[0039] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0040] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
