Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a textured wire drawing device and system. Background Technology

[0002] In the fields of stainless steel decoration, home appliances, and automotive interiors, steel sheets need to be processed by grinding and wire drawing machines to form a surface that combines a smooth base with regular textures, thereby enhancing the appearance and texture. However, the core defects of the current equipment are extremely prominent. The steel sheets produced after processing have overly obvious and uneven textures, which are manifested in the following ways: the difference in texture coarseness is directly identifiable to the naked eye, the density distribution is disordered, and in some areas the textures are densely overlapping to form dark patches, while adjacent areas are sparsely scattered to present light-colored gaps. Under strong light, the contrast between light and dark is strong, and the visual disjointedness is obvious. More commonly, there are defects such as texture breakage and directional deviation, with obvious blank gaps formed at the broken lines, directly presenting a messy appearance. As a result, the products lose their eligibility for high-end market access due to appearance defects.

[0003] Furthermore, variations in texture depth result in excessive coating buildup in deeper textures and insufficient coverage in shallower textures, leading to poor coating uniformity and significantly reducing product durability. In addition, texture defects cause low first-pass yield rates for high-end steel sheet wire drawing, requiring rework, repeated wire drawing, or recoating. This not only significantly increases costs but also severely impacts steel sheet processing efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem of poor uniformity of steel plate wire drawing in the prior art, and to provide a wire drawing equipment and system with superimposed texture.

[0005] To solve the above-mentioned technical problems, this utility model provides a textured wire drawing device, comprising: a frame; a transmission assembly disposed on the frame; at least two homogenizing wire drawing mechanisms arranged along the transmission direction of the transmission assembly; each homogenizing wire drawing mechanism including a fixed beam, a wire drawing assembly, and a swinging assembly; the fixed beam being connected to the frame; the wire drawing assembly including a wire drawing driver and a wire drawing roller; the wire drawing driver being connected to the fixed beam, its working end being connected to the wire drawing roller to drive the wire drawing roller to rotate... The axis of rotation is defined as follows: the oscillating assembly includes an oscillating driver, an oscillating frame, an eccentric component, and a driving rod. The oscillating driver is connected to the fixed beam. The eccentric component is disposed at the working end of the oscillating driver. The two ends of the driving rod are rotatably connected to the eccentric component and the oscillating frame, respectively, to drive the oscillating frame to oscillate. The wire drawing roller is disposed on the oscillating frame and moves synchronously with the oscillating frame. The eccentric component in at least two of the homogenizing wire drawing mechanisms includes at least two types of eccentricity, and the homogenizing wire drawing mechanism with the largest eccentricity is disposed near the discharge end of the transmission assembly.

[0006] In one embodiment of this utility model, mounting brackets and connecting brackets are respectively provided on opposite sides in the thickness direction of the fixed beam. The mounting bracket is disposed above the connecting bracket and extends through the top of the frame. The connecting bracket is disposed towards the transmission component. The wire drawing driver is disposed on the mounting bracket. The swing bracket is slidably connected to the connecting bracket.

[0007] In one embodiment of this utility model, the swing frame is provided with a connecting shaft, which passes through the connecting frame and can drive the swing frame to move along its axial direction.

[0008] In one embodiment of the present invention, the swing assembly further includes a transmission shaft, the two ends of which are respectively connected to the working end of the swing driver and the eccentric member to drive the eccentric member to rotate.

[0009] In one embodiment of this utility model, the swing frame is further provided with a fixing member, and the transmission shaft is rotatably connected to the fixing member.

[0010] In one embodiment of the present invention, the wire drawing assembly includes a transmission belt, which is sleeved on the working end of the wire drawing driver and the roller shaft of the wire drawing roller.

[0011] In one embodiment of this utility model, the eccentric distance of the eccentric component is 5~10mm.

[0012] In one embodiment of this utility model, the texture superposition wire drawing equipment further includes a water spraying mechanism. The water spraying mechanism is disposed on the swing frame and includes a tube body, multiple nozzles and a baffle plate. A water supply device is connected to the outside of the tube body and is arranged parallel to one side of the wire drawing roller. The multiple nozzles are evenly spaced on the tube body and all face the wire drawing roller. Each nozzle is equipped with a fan-shaped nozzle. The baffle plate is disposed on opposite sides of the wire drawing roller.

[0013] In one embodiment of the present invention, the texture superposition drawing device further includes a plurality of elastic dewatering rollers, which are arranged on opposite sides of the drawing roller along the transmission direction of the transmission component.

[0014] This utility model also provides a textured wire drawing system, which includes the above-mentioned textured wire drawing equipment.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: The texture superposition wire drawing equipment and system of this utility model are provided with at least two homogenizing wire drawing mechanisms along the direction of the transmission component. Each mechanism is equipped with an independent swing component. The swing driver drives the swing frame to swing back and forth through the eccentric part and the drive rod, so that the wire drawing roller can achieve dynamic swing while rotating and drawing wire. This composite motion mode can effectively break the directional deep texture that is easily formed by traditional single-direction wire drawing. Through the superposition of textures of multiple mechanisms, the surface texture of the steel plate becomes more delicate and uniform, fundamentally improving the problem of large differences in texture coarseness and strong contrast between light and dark after processing by traditional equipment. Crucially, the eccentric components in at least two homogenizing wire drawing mechanisms employ at least two different eccentricity designs, with the mechanism having the largest eccentricity positioned closer to the discharge end. The front-end mechanism can achieve initial texture shaping with a smaller eccentricity, reducing the impact of initial defects on the steel plate surface on subsequent processing. The rear-end mechanism with the largest eccentricity can perform deep homogenization and superposition modification of the texture formed at the front end through a larger range of oscillation, resulting in a final texture that is both regular and delicate. This avoids the problem of ineffective texture superposition and noticeable traces caused by consistent parameters in traditional multi-process processing.

[0016] Compared to current conventional processing technologies, this equipment does not rely on high-cost single components. Instead, it improves texture quality through structural optimization and process synergy, making the overall cost more affordable for small and medium-sized enterprises and solving the problem of limited adoption of traditional high-precision equipment. Furthermore, the integrated design of the multi-uniformity drawing mechanism allows for multiple texture processing steps to be completed in a single transfer, eliminating the need for additional processes and effectively ensuring processing efficiency while balancing quality and production capacity requirements. In addition, by improving texture uniformity, this equipment reduces uneven coating adhesion caused by texture defects, enhances the corrosion resistance and fatigue resistance of steel plates, extends product lifespan, and increases the first-pass yield of steel plates, reducing rework costs and material waste, effectively overcoming existing technological bottlenecks.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0021] Example 1: See Figure 1As shown, this embodiment provides a textured wire drawing device, which includes: a frame 100; a transmission assembly 200 disposed on the frame 100; at least two homogenizing wire drawing mechanisms 300, the at least two homogenizing wire drawing mechanisms 300 being arranged along the transmission direction of the transmission assembly 200. Each homogenizing wire drawing mechanism 300 includes a fixed beam 310, a wire drawing assembly 320, and a swing assembly 330. The fixed beam 310 is connected to the frame 100. The wire drawing assembly 320 includes a wire drawing driver 321 and a wire drawing roller 323. The wire drawing driver 321 is connected to the fixed beam 310, and its working end is connected to the wire drawing roller 323 to drive the wire drawing roller 323 around its central axis. The oscillating assembly 330 includes an oscillating driver 332, an oscillating frame 331, an eccentric member 334, and a driving rod 335. The oscillating driver 332 is connected to the fixed beam 310. The eccentric member 334 is disposed at the working end of the oscillating driver 332. The two ends of the driving rod 335 are rotatably connected to the eccentric member 334 and the oscillating frame 331, respectively, to drive the oscillating frame 331 to oscillate. The wire drawing roller 323 is disposed on the oscillating frame 331 and moves synchronously with the oscillating frame 331. The eccentric member 334 in at least two homogenizing wire drawing mechanisms 300 includes at least two eccentricities, and the homogenizing wire drawing mechanism 300 with the largest eccentricity is disposed near the discharge end of the transmission assembly 200.

[0022] The texture superposition wire drawing equipment shown in this embodiment is provided with at least two homogenizing wire drawing mechanisms 300 along the direction of the transmission component 200. Each mechanism is equipped with an independent swing component 330. The swing driver 332 drives the swing frame 331 to swing back and forth through the eccentric part 334 and the drive rod 335, thereby enabling the wire drawing roller 323 to achieve dynamic swing while rotating and drawing wire. This composite motion mode can effectively break the directional deep texture that is easily formed by traditional single-direction wire drawing. Through the superposition of textures of multiple mechanisms, the surface texture of the steel plate becomes more delicate and uniform, fundamentally improving the problem of large differences in texture coarseness and strong contrast between light and dark after processing by traditional equipment. Crucially, the eccentric components 334 in at least two homogenizing wire drawing mechanisms 300 employ at least two different eccentricity designs, with the mechanism having the largest eccentricity positioned closer to the discharge end. The front-end mechanism can achieve initial texture shaping with a smaller eccentricity, reducing the impact of initial defects on the steel plate surface on subsequent processing. The rear-end mechanism with the largest eccentricity can perform deep homogenization and superposition modification of the texture formed at the front end through a larger range of oscillation, resulting in a final texture that is both regular and delicate. This avoids the problem of ineffective texture superposition and obvious traces caused by consistent parameters in traditional multi-process processing.

[0023] In this embodiment, the frame 100 serves as the basic support structure of the equipment. Through a stable frame design, it provides a solid installation reference for the transmission component 200, the homogenizing wire drawing mechanism 300, etc., ensuring that each component will not be displaced due to vibration or force during equipment operation. This avoids the decrease in wire drawing accuracy caused by component position deviation. At the same time, it provides a stable working platform for the entire equipment, ensuring that the relative position of the steel plate transmission path and the wire drawing component 320 is always accurate during processing. This is the basic guarantee for the stability of equipment operation.

[0024] Furthermore, the transmission component 200 is mounted on the frame 100, and its core function is to achieve continuous and uniform transmission of the steel plate, providing a prerequisite for the orderly implementation of multiple homogenization and wire drawing processes. It uses a motor-driven conveyor belt to transport the steel plate to be processed from the feed end to the discharge end at a preset speed, thereby allowing the steel plate to pass sequentially through multiple homogenization and wire drawing mechanisms 300 arranged along the transmission direction, ensuring that each wire drawing process covers the entire surface of the steel plate. In different embodiments, the transmission component 200 can be configured as other types of transmission components such as transmission rollers according to actual practical needs; this utility model does not impose specific limitations in this regard.

[0025] See Figures 2 to 7 As shown, the arrangement of at least two homogenizing wire drawing mechanisms 300 along the transmission direction of the transmission component 200 enables them to perform staged and progressive wire drawing processing on the steel plate, forming a complete local wire drawing system. The fixed beam 310 serves as a local support frame for the homogenizing wire drawing mechanism 300, with one end connected to the frame 100 and the other end used to fix the wire drawing component 320 and the swing component 330. Its rigid structural design ensures the relative stability of the relative positions of the power components such as the wire drawing driver 321 and the swing driver 332 with the execution components such as the wire drawing roller 323 and the swing frame 331, preventing fluctuations in the contact pressure between the wire drawing roller 323 and the steel plate due to component vibration. It also provides a precise positioning reference for the installation and debugging of each component, which is fundamental to ensuring the working accuracy of a single homogenizing wire drawing mechanism 300.

[0026] Specifically, the fixed beam 310 has a mounting frame 311 and a connecting frame 312 on opposite sides in the thickness direction. The mounting frame 311 is located above the connecting frame 312 and extends through the top of the frame 100. The connecting frame 312 is positioned towards the transmission assembly 200. The wire drawing driver 321 is mounted on the mounting frame 311. The swing frame 331 is slidably connected to the connecting frame 312. Furthermore, the swing frame 331 has a connecting shaft 3311, which passes through the connecting frame 312 and can drive the swing frame 331 to move along its axial direction. The fixed beam 310 is designed with mounting brackets 311 and connecting brackets 312 on both sides in the thickness direction. The mounting brackets 311 provide a stable installation space for the wire drawing driver 321 away from the transmission area, avoiding the influence of processing dust on the driver. The connecting brackets 312 and the sliding connection with the swing frame 331 provide precise guidance for the reciprocating swing of the swing frame 331, ensuring that the wire drawing roller 323 always maintains stable contact with the steel plate surface when it moves with the swing frame 331, further improving the uniformity of the wire drawing texture.

[0027] In this embodiment, the wire drawing assembly 320 serves as a wire drawing execution unit that directly acts on the surface of the steel plate, undertaking the function of rotary grinding and preliminary shaping of the texture on the steel plate. The wire drawing driver 321 is preferably a rotary motor, which serves as a power source and is connected to the wire drawing roller 323 via a belt drive. The transmission belt 322 is sleeved on the working end of the wire drawing driver 321 and the roller shaft of the wire drawing roller 323 to drive the wire drawing roller 323 to rotate around its central axis, providing sufficient grinding power for the wire drawing roller 323. During rotation, the wire drawing roller 323 contacts the surface of the steel plate, forming an initial wire drawing texture on the steel plate surface through the cutting action of the abrasive. Furthermore, it is mounted on the swing frame 331, providing a structural basis for subsequent swing motion and avoiding the defect of traditional fixed wire drawing rollers 323 that can only form directional deep lines.

[0028] In this embodiment, the oscillating component 330 is the core structure for realizing the dynamic oscillation of the wire drawing roller 323. It converts rotational power into oscillating motion through mechanical transmission, giving the wire drawing roller 323 a composite motion trajectory of rotation and oscillation. Specifically, the oscillating driver 332 is preferably a rotary motor, with the working end connected to the eccentric component 334. When the oscillating driver 332 drives the eccentric component 334 to rotate around its own axis, the eccentric component 334, due to the structural characteristic of the eccentricity between the rotation center and the geometric center, will convert the rotational motion into reciprocating thrust through the drive rod 335, driving the oscillating frame 331 connected to it to oscillate back and forth around the fixed axis. The wire drawing roller 323 is set on the oscillating frame 331 and will oscillate back and forth synchronously with the oscillating frame 331, so that while the wire drawing roller 323 is rotating and grinding the steel plate, it can move slightly along the dimension perpendicular to the transmission direction, thereby forming a composite texture of rotational grinding texture and oscillation superposition texture on the surface of the steel plate, avoiding obvious deep lines formed by wire drawing in one direction, and achieving preliminary homogenization of the texture.

[0029] Specifically, the swing assembly 330 further includes a drive shaft 333, the two ends of which are respectively connected to the working end of the swing driver 332 and the eccentric member 334 to drive the eccentric member 334 to rotate. The swing frame 331 is also provided with a fixing member 3312, to which the drive shaft 333 is rotatably connected. This achieves a stable drive structure.

[0030] Crucially, the homogenizing wire drawing mechanism near the discharge end has the largest eccentricity of 300 and a larger swing amplitude, which can deeply superimpose and modify the basic texture formed at the front end. Through the larger swing wire drawing, it further breaks down the obvious texture remaining in some areas, making the final texture more uniform and delicate. Moreover, the superimposed texture can cover up the slight unevenness that may exist in the front end processing, realizing the progressive processing from basic shaping to fine homogenization, and ultimately achieving the core goal of improving obvious unevenness of texture.

[0031] Specifically, in this embodiment, four homogenizing wire drawing mechanisms 300 are provided, wherein the minimum eccentricity distance of the eccentric member 334 is 5mm and the maximum eccentricity distance is 10mm. In different embodiments, the homogenizing wire drawing mechanisms 300 can be set to other numbers or different eccentric swing distances according to actual practical needs. Homogenizing wire drawing mechanisms 300 with larger eccentricity distances and homogenizing wire drawing mechanisms 300 with smaller eccentricity distances can be alternately arranged or grouped together. This utility model does not impose specific limitations in this regard.

[0032] Furthermore, the textured wire drawing device in this embodiment also includes a water spraying mechanism 400, which is disposed on the swing frame 331. The water spraying mechanism 400 includes a tube body 410, multiple nozzles 420, and a baffle plate 430. The tube body 410 is externally connected to a water supply device, which is arranged parallel to one side of the wire drawing roller 323. The multiple nozzles 420 are evenly spaced on the tube body 410 and are all facing the wire drawing roller 323. Each nozzle 420 is equipped with a fan-shaped nozzle. The baffle plate 430 is disposed on opposite sides of the wire drawing roller 323. Specifically, the water spray mechanism 400 installed on the swing frame 331 can clean the wire drawing roller 323 with a uniform water flow and avoid secondary grinding, cool the wire drawing roller 323 to extend the abrasive life, and also restrict the water flow through the baffle plate 430 to prevent equipment corrosion and sewage diffusion. Together with the swing frame 331 and the wire drawing roller 323, it can ensure the uniformity of the wire drawing pattern and improve the stability and economy of equipment operation.

[0033] Furthermore, the textured wire drawing equipment also includes multiple elastic dewatering rollers 500, which are arranged on opposite sides of the wire drawing roller 323 along the transmission direction of the transmission component 200. This invention does not limit the specific number of elastic dewatering rollers 500.

[0034] Example 2:

[0035] This embodiment provides a textured wire drawing system, which includes the textured wire drawing equipment described in Embodiment 1.

[0036] In summary, compared to current conventional processing technologies, this application does not rely on high-cost single components. Instead, it achieves improved texture quality through structural optimization and process synergy, making the overall equipment cost more acceptable to small and medium-sized enterprises and solving the problem of the difficulty in popularizing traditional high-precision equipment. Simultaneously, the integrated design of the multi-homogenization drawing mechanism 300 can complete multiple texture processing steps in a single transmission process without adding extra procedures, effectively ensuring processing efficiency and balancing quality and production capacity requirements. Furthermore, by improving texture uniformity, this equipment reduces uneven coating adhesion caused by texture defects, enhances the corrosion resistance and fatigue resistance of steel plates, extends product lifespan, and increases the first-pass yield of steel plates, reducing rework costs and material waste, effectively overcoming existing technological bottlenecks.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
