Description

Technical Field

[0001] This utility model belongs to the field of traction technology, and specifically relates to a traction device for a wire drawing machine. Background Technology

[0002] The traction device of a wire drawing machine plays a crucial role in the metal wire drawing process. Its main function is to draw the metal wire after it has been stretched by the drawing die and wind it up to form a coil of wire of a certain length.

[0003] However, current wire drawing machine traction devices have a significant problem: the traction and winding components have a single diameter. Because the diameter of the winding components cannot be adjusted to meet different winding requirements, production flexibility is severely limited. In actual production, different customers or different products may require wire coils of different diameters. However, existing traction devices cannot meet these diverse needs and can only wind wire at a fixed diameter. This necessitates changing different traction and winding devices to meet different requirements, increasing equipment costs, extending downtime, and reducing production efficiency.

[0004] To address this problem, this application proposes a wire drawing machine traction device. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a wire drawing machine traction device. By designing an adjustable traction mechanism, the distance between multiple sets of arc-shaped plates can be adjusted according to diverse traction and winding requirements. This adjustment makes the entire traction and winding process more flexible. When producing metal wire products of different specifications, or in response to customized needs from different customers, the arc-shaped plates can be adjusted to suitable positions according to actual requirements, thereby forming metal wire coils of different diameters during the traction and winding process. This solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A wire drawing machine traction device includes a frame, with an adjustable traction mechanism on the inner side of the frame. The adjustable traction mechanism includes two sets of limiting plates on the inner side of the frame, multiple sets of arc-shaped plates between the two sets of limiting plates, and a central screw cylinder between the multiple sets of arc-shaped plates. A central lead screw is internally threaded into the central screw cylinder. Multiple sets of movable connecting rods are provided on the outer side of the central screw cylinder. One end of each movable connecting rod is movably connected to an arc-shaped plate, and the other end is movably connected to the central screw cylinder. Multiple sets of guide grooves are formed on the opposite surfaces of the two sets of limiting plates, and a slider is slidably disposed in the guide groove.

[0008] Through the above technical solution, when the central lead screw rotates inside the central screw cylinder, based on the principle of threaded transmission, the central screw cylinder can be adjusted up and down. When the central screw cylinder rises or falls, it will pull or push multiple sets of arc-shaped plates through the movable connecting rod, causing the arc-shaped plates to move closer or further apart from each other.

[0009] In a preferred embodiment, one end of the slider is fixedly connected to the arc plate, and an adjustable motor is installed on the upper surface of the upper limiting plate. The output shaft of the adjustable motor is fixedly connected to the central lead screw.

[0010] The above technical solution enables the adjustable pitch motor to drive the central lead screw to rotate inside the central screw barrel.

[0011] In a preferred embodiment, the arc-shaped plate is provided in six groups, the six groups of arc-shaped plates are equidistantly distributed, and the six groups of arc-shaped plates are combined to form a circular structure.

[0012] Through the above technical solution, the distance between the arc plates can be adjusted when they are close to or far from each other, so as to meet the actual requirements for the diameter and length of the wire traction and winding during the traction and winding process.

[0013] In a preferred embodiment, a disassembly and assembly mechanism is provided below the frame. The disassembly and assembly mechanism includes a fixed platform fixed below the frame, a drive screw is provided above the fixed platform, and a long screw is threadedly connected above the drive screw.

[0014] With the above technical solution, when the drive screw rotates inside the long screw barrel, it can drive the long screw barrel to rise and fall.

[0015] In a preferred embodiment, a support plate is fixedly connected above the long screw cylinder, and an annular groove is formed at the outer edge of the upper surface of the support plate, with the annular groove opening towards the limiting plate.

[0016] Through the above technical solution, when the long screw cylinder is raised and lowered, it can drive the support plate to be raised and lowered synchronously.

[0017] In a preferred embodiment, the annular groove is provided with multiple sets of universal balls, the upper ends of the universal balls are fixedly connected to the limiting plate, the rolling part of the universal balls is in contact with the bottom surface of the annular groove, and the multiple sets of universal balls are equidistantly distributed along the path of the annular groove.

[0018] With the above technical solution, during the traction and winding operation, the lower limit plate will drive multiple sets of universal balls to slide along the annular groove path, thereby improving the smoothness of the rotation of the pitch-adjusting traction mechanism.

[0019] In a preferred embodiment, a height adjustment motor is installed below the fixed platform. The output shaft of the height adjustment motor is fixedly connected to a drive screw. A set of synchronizing rods are fixedly connected to both sides of the support plate. One end of each synchronizing rod has a guide hole, and a guide rod is installed inside the guide hole. The lower end of the guide rod is fixedly connected to the fixed platform.

[0020] With the above technical solution, when the drive screw cylinder lowers the support plate, the support plate lowers the synchronous rod, and simultaneously causes the guide hole to slide along the path of the guide rod, thus improving the stability of the support plate's descent.

[0021] In a preferred embodiment, a top circular plate is provided above the adjustable motor, and a hexagonal groove is provided in the middle of the upper surface of the top circular plate. The bottom of the top circular plate is fixedly connected to the limiting plate by three sets of fixing rods. A hexagonal drive rod is provided in the hexagonal groove. A traction motor is fixedly installed above the frame, and the output shaft of the traction motor is fixedly connected to the hexagonal drive rod.

[0022] With the above technical solution, when the traction motor starts, it can drive the hexagonal drive rod to rotate, which in turn drives the top circular plate to rotate, thereby driving the upper limit plate to rotate. The upper limit plate drives multiple sets of arc plates to rotate, thus realizing the traction and winding of the metal wire.

[0023] After adopting the above technical solution, the beneficial effects of this utility model are:

[0024] 1. By designing an adjustable traction mechanism, the distance between multiple sets of arc plates can be adjusted according to diverse traction and winding requirements. This adjustment makes the entire traction and winding process more flexible. When producing metal wire products of different specifications, or in response to the customized needs of different customers, the arc plates can be adjusted to the appropriate position according to actual needs, thereby forming metal wire rolls of different diameters during the traction and winding process. This avoids the drawback of traditional devices that have to frequently change equipment due to the single diameter of the winding components, and improves the flexibility and adaptability of production.

[0025] 2. By designing a disassembly and assembly mechanism, after the traction and winding of the metal wire coil is completed, the disassembly and assembly mechanism can easily disassemble the pitch adjustment traction mechanism from the current workstation. The operation process is simple and smooth, without complicated tools and cumbersome steps. This convenient disassembly and assembly method brings great convenience to the workstation transfer operation. After the pitch adjustment traction mechanism is quickly disassembled, it can be immediately transferred to the next workstation, thereby avoiding the time delay caused by the difficulty of disassembly and assembly in traditional devices, effectively shortening the connection time between different processes and improving work efficiency.

[0033] 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.

[0034] Please see Figures 1 to 5A wire drawing machine traction device includes a frame 1, with an adjustable traction mechanism 4 on the inner side of the frame 1. The adjustable traction mechanism 4 includes two sets of limiting plates 41 on the inner side of the frame 1, multiple sets of arc plates 42 between the two sets of limiting plates 41, and a central screw 43 between the multiple sets of arc plates 42. A central screw rod 45 is threadedly connected to the central screw 43. Multiple sets of movable connecting rods 44 are provided on the outer side of the central screw 43. One end of the movable connecting rod 44 is movably connected to the arc plate 42, and the other end of the movable connecting rod 44 is movably connected to the central screw 43. Multiple sets of guide grooves 46 are opened on the opposite surfaces of the two sets of limiting plates 41, and sliders 47 are slidably arranged in the guide grooves 46.

[0035] When the central lead screw 45 rotates inside the central screw cylinder 43, based on the principle of threaded transmission, the central screw cylinder 43 can be adjusted up and down. When the central screw cylinder 43 rises or falls, it will pull or push multiple sets of arc plates 42 through the movable connecting rod 44, causing the arc plates 42 to move closer or further apart from each other.

[0036] One end of the slider 47 is fixedly connected to the arc plate 42, and an adjustable motor 411 is installed on the upper surface of the upper limit plate 41. The output shaft of the adjustable motor 411 is fixedly connected to the central lead screw 45.

[0037] The adjustable pitch motor 411 can drive the central lead screw 45 to rotate inside the central screw barrel 43.

[0038] There are six sets of arc-shaped plates 42, which are equidistantly distributed and combined to form a circular structure.

[0039] When the arc plates 42 move closer or further apart, the distance between them can be adjusted to meet the actual requirements for the diameter and length of the wire during the traction and winding process.

[0040] The frame 1 is provided with a disassembly and assembly mechanism 3. The disassembly and assembly mechanism 3 includes a fixed platform 31 fixed below the frame 1. A drive screw 33 is provided above the fixed platform 31. A long screw cylinder 35 is threadedly connected above the drive screw 33.

[0041] When the drive screw 33 rotates inside the long screw barrel 35, it can drive the long screw barrel 35 to rise and fall.

[0042] A support plate 36 is fixedly connected above the long screw cylinder 35. An annular groove 37 is provided on the outer edge of the upper surface of the support plate 36, and the annular groove 37 opens toward the limiting plate 41.

[0043] When the long screw 35 is raised or lowered, it can drive the support plate 36 to be raised or lowered synchronously.

[0044] Multiple sets of universal balls 38 are provided in the annular groove 37. The upper end of the universal ball 38 is fixedly connected to the limiting plate 41. The rolling part of the universal ball 38 contacts the bottom surface of the annular groove 37. The multiple sets of universal balls 38 are equidistantly distributed along the path of the annular groove 37.

[0045] During the traction and winding operation, the lower limit plate 41 will drive multiple sets of universal balls 38 to slide along the path of the annular groove 37, thereby improving the smoothness of the rotation of the pitch traction mechanism 4.

[0046] A height adjustment motor 32 is installed below the fixed platform 31. The output shaft of the height adjustment motor 32 is fixedly connected to the drive screw 33. A set of synchronous rods 39 are fixedly connected to both sides of the support plate 36. A guide hole is opened at one end of the synchronous rod 39, and a guide rod 34 is provided in the guide hole. The lower end of the guide rod 34 is fixedly connected to the fixed platform 31.

[0047] When the drive screw 35 lowers the support plate 36, the support plate 36 lowers the synchronous rod 39, and simultaneously causes the guide hole to slide along the path of the guide rod 34, improving the stability of the support plate 36 during descent.

[0048] A top circular plate 49 is provided above the pitch motor 411. A hexagonal groove is provided in the middle of the upper surface of the top circular plate 49. The bottom of the top circular plate 49 is fixedly connected to the limiting plate 41 by three sets of fixing rods 48. A hexagonal drive rod 410 is provided in the hexagonal groove. A traction motor 2 is fixedly installed above the frame 1. The output shaft of the traction motor 2 is fixedly connected to the hexagonal drive rod 410.

[0049] When the traction motor 2 starts, it can drive the hexagonal drive rod 410 to rotate, which in turn drives the top circular plate 49 to rotate, thereby driving the upper limit plate 41 to rotate. The upper limit plate 41 drives multiple sets of arc plates 42 to rotate, thus realizing the traction and winding of the metal wire.

[0050] In practical use, the working principle of this utility model is as follows:

[0051] In use, the adjustable-pitch motor 411 drives the central lead screw 45 to rotate within the central screw cylinder 43, utilizing the threaded transmission principle to adjust the vertical movement of the central screw cylinder 43. When the central screw cylinder 43 rises or falls, it pulls or pushes multiple sets of arc-shaped plates 42 via the movable connecting rod 44, which in turn causes the slider 47 to slide along the guide groove 46, causing the multiple sets of arc-shaped plates 42 to move closer or further apart. This operation allows for flexible adjustment of the distance between the arc-shaped plates 42 according to different traction and winding requirements, satisfying the actual needs for the diameter and length of the metal wire during traction and winding, thus forming metal wire coils of different diameters. After the adjustment operation is completed, the metal wire to be traction is securely fixed to the arc-shaped plates 42. Subsequently, the traction motor 2 starts, driving the hexagonal drive rod 410 to rotate. The hexagonal drive rod 410 then drives the top circular plate 49 to rotate, which in turn drives the upper limiting plate 41 to rotate via the fixed rod 48. The upper limiting plate 41 then drives the multiple sets of arc-shaped plates 42 to rotate, thereby achieving the traction and winding of the metal wire. As the arc plate 42 rotates, the lower limiting plate 41 will drive multiple sets of universal balls 38 to slide along the path of the annular groove 37, thereby improving the smoothness of the rotation of the pitch adjustment traction mechanism 4 and ensuring the smoothness of the entire traction and winding process.

[0052] After the traction and winding work is completed, the height adjustment motor 32 drives the drive screw 33 to rotate inside the long screw barrel 35, which in turn drives the support plate 36 to descend. The support plate 36 drives the synchronous rod 39 to descend, and at the same time, it drives the guide hole to slide along the path of the guide rod 34, improving the stability of the descent of the support plate 36. Thus, the support plate 36 drives the overall descent of the pitch adjustment traction mechanism 4, allowing the hexagonal slot to disengage from the outside of the hexagonal drive rod 410. After the descent is completed, it is easy to lift the pitch adjustment traction mechanism 4 upward and disassemble it, so that it can be quickly transferred to the next station after the wire traction and winding is completed, achieving efficient station transfer operation and improving work efficiency. Conversely, the pitch adjustment traction mechanism 4 can be installed.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
