Description

Technical Field

[0001] This invention relates to the field of surface sandblasting technology, and more specifically to a through-type wire sandblasting machine. Background Technology

[0002] In the current production process of refined wire rod, through-feed sandblasting machines play a crucial role. They effectively clean impurities and irregularities from the wire rod surface by spraying high-speed abrasive particles, providing a solid foundation for subsequent processing. However, this step also faces a series of technical challenges, especially in dealing with high-speed flying abrasive particles.

[0003] These high-speed abrasive grains, with their extremely high velocity and sharpness, cause severe wear to traditional rolling guide rollers. The guide rollers are crucial components for wire transport, and their stability and durability are essential for the smooth operation of the sandblasting process. However, under continuous impact from high-speed abrasive grains, the guide rollers struggle to maintain stable operation for extended periods. This not only affects the stability of the wire during sandblasting but also directly leads to a decline in wire quality.

[0004] Even more challenging is that the wire, during transport within the sandbox, often exists in an unstable, suspended, and vibrating state due to the lack of proper support and positioning devices. This vibration causes the distance and angle between the wire surface and the spray gun to constantly change, resulting in severely uneven sandblasting effects. This vibration problem is particularly pronounced when processing wires with iron oxide scale on their surface. The irregularity and roughness of the iron oxide scale increase the difficulty of sandblasting, while the wire's vibration further exacerbates the unevenness of the cleaning process.

[0005] This uneven sandblasting process not only fails to completely remove the iron oxide scale, but may also leave noticeable marks and irregularities. These residues and irregular surfaces severely affect the appearance quality of the wire, reducing its overall aesthetics and smoothness. More seriously, this uneven cleaning effect can also have a severe negative impact on the subsequent phosphating process.

[0006] Phosphating is an important surface treatment process that forms a uniform and dense phosphate layer on the surface of wire through a chemical reaction. This phosphate layer can significantly improve key properties of the wire, such as corrosion resistance, mechanical strength, and adhesion. However, due to uneven sandblasting caused by vibration, a uniform and dense phosphate layer often cannot be formed on the wire surface during the phosphating process. This uneven phosphate layer not only affects the appearance quality of the wire, but more importantly, it reduces its overall performance and service life. Summary of the Invention

[0007] To address the aforementioned problems, the present invention aims to provide a through-feed wire sandblasting machine that effectively eliminates the vibration phenomenon generated during wire operation, ensuring the wire remains stably within the working area of ​​the sandblasting gun. This guarantees that every part of the wire surface receives uniform and sufficient sandblasting treatment, completely removing surface iron oxide scale and providing a uniformly rough and uneven surface for subsequent phosphating reactions. Consequently, a more uniform and dense phosphating layer is obtained, improving the overall mechanical properties and service life of the wire and providing strong technical support for the production and application of refined wire.

[0016] In a preferred embodiment, the fixing part is provided with a plurality of mounting holes spaced apart along the circumferential direction on the side near the top wall, and the positioning device is fixedly connected to the mounting plate through the mounting holes.

[0017] In a preferred embodiment, a mounting plate is provided between the first fixing plate and the second fixing plate, a first sandblasting area is formed between the mounting plate and the first fixing plate, and a second sandblasting area is formed between the mounting plate and the second fixing plate.

[0018] In a preferred embodiment, the sandblasting gun is mounted on the mounting rod, and the sandblasting nozzle of the sandblasting gun is close to the surface of the wire.

[0019] In a preferred embodiment, the first fixing seat and the second fixing seat are provided with a connecting frame.

[0020] The through-type wire blasting machine disclosed in this invention has the following advantages compared with the prior art:

[0021] (1) The through-type wire sandblasting machine presented in this invention is a surface treatment device with a unique structure and comprehensive functions. It includes at least a fixing device, a positioning device, several sandblasting guns, and a high-pressure liquid supply system. The synergistic effect of these components enables the wire to be transported stably and efficiently during the sandblasting process, while ensuring the uniformity and quality of the treatment effect. The fixing device is the basic part of the sandblasting machine, which includes a first fixing seat and a second fixing seat arranged symmetrically. A coaxial slot is provided between the two fixing seats for the smooth passage of the wire. This design not only ensures the stability of the wire during the transport process, but also provides a good foundation for the subsequent sandblasting process. Between the fixing seats, at least one positioning device and several sandblasting guns are arranged at intervals along the wire transport direction. The main function of the positioning device is to ensure the radial positioning of the wire during the sandblasting process and prevent it from shaking or shifting due to uneven force. Each positioning device includes a sleeve and a transport pipe. The sleeve has a cavity structure that runs through the front and back, and its outer wall surface is provided with multiple liquid flow holes at intervals along the circumferential direction. One end of the delivery pipe is connected to the high-pressure liquid supply system, and the other end is connected to the liquid flow orifice. The high-pressure liquid supply system delivers high-pressure fluid to the cavity of the bushing through the delivery pipe and the liquid flow orifice. When the high-pressure fluid enters the gap between the bushing and the wire through the liquid flow orifice, a high-pressure chamber is formed, which radially positions and supports the wire surface, thereby ensuring its stability. Simultaneously, this high-pressure chamber design has another important function: during wire transport, the high-pressure chamber sprays high-pressure fluid through the gap between the wire and the bushing. This spraying action can wash away impurities such as steel shot adhering to the wire surface, thus avoiding the risk of scratches from steel shot. This not only ensures the surface quality of the wire but also extends its service life. The sandblasting gun is responsible for sandblasting the wire surface. With the cooperation of the positioning device, the sandblasting gun can precisely and efficiently sandblast the wire surface, thereby removing surface dirt, oxide layers, and other undesirable substances, improving the surface smoothness and adhesion of the wire.

[0022] (2) The through-type wire sandblasting machine designed in this invention has undergone thoughtful optimization in its overall structural layout, especially in the configuration of the sandblasting area and the sandblasting guns, ensuring that the wire can be fully and uniformly treated when passing through. Specifically, the first fixed plate and the second fixed plate, as the core support parts of the sandblasting machine, are firmly fixed on the first fixed seat and the second fixed seat. The mounting plate set between them not only plays a role in connecting and reinforcing, but also cleverly divides the entire sandblasting area into two parts, forming the first sandblasting area and the second sandblasting area. This partitioned design allows the wire to pass through two different treatment areas successively during continuous passage, achieving a more detailed and comprehensive sandblasting effect. In these two sandblasting areas, several sandblasting guns are arranged in a staggered manner along the circumference. This layout ensures that no matter which part of the wire is covered by the sandblasting guns. The sandblasting nozzle of each sandblasting gun has been precisely designed and adjusted so that it can be close to the surface of the wire, thereby ensuring the uniformity and consistency of sandblasting. When the wire passes through the first sandblasting area, its surface will first be impacted by a ring of high-pressure sand flow. These high-speed rotating abrasive particles quickly remove dirt, oxide layers, and other unwanted deposits from the wire surface. Simultaneously, a positioning device on the mounting plate jets high-pressure fluid, continuously rinsing the wire surface. This step not only removes residual sand and impurities but also pre-treats the wire surface before it enters the second sandblasting zone, making it cleaner and smoother. After the first sandblasting zone, the wire surface has undergone preliminary cleaning and smoothing. When it enters the second sandblasting zone, it is again subjected to the impact and friction of the high-pressure abrasive stream, undergoing a more meticulous and in-depth sandblasting process. This secondary treatment further improves the surface finish and adhesion of the wire, achieving a higher quality standard.

[0023] (3) One end of the sleeve is embedded in the mounting cavity of the fixing seat and abuts against the side of the top wall near the mounting cavity. The top wall is provided with an outlet that matches the cavity of the sleeve. The outlet of the fixing seat is on the same axis as the slot of the first fixing seat and the second fixing seat for the wire to pass through. This design ensures that the wire can maintain a straight trajectory when passing through these components, thereby avoiding fluid leakage or wire damage that may be caused by bending or twisting. When the positioning device is installed, the wire enters from the bottom opening of the fixing seat and exits from the outlet of the fixing seat and passes through the cavity of the sleeve located inside the fixing seat. This design can effectively ensure that the sleeve and the fixing seat are tightly abutted. This tight fit is the key to ensuring that the high-pressure fluid can flow along the predetermined path, thereby ensuring that the high-pressure fluid flows into the gap between the wire and the sleeve in sequence from the delivery pipe, the inlet hole and the flow hole, and radially fixes the wire and axially sprays high-pressure fluid. In this process, the fluid not only radially fixes the wire to ensure that it will not shake or deviate during operation, but also performs high-pressure spraying along the axial direction of the wire. This spraying method not only improves the efficiency of fluid transmission, but also helps to clean and lubricate the wires, thereby further improving the reliability and service life of the entire system.

Therefore, they should not be construed as limitations on this invention.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] This embodiment of a through-type sandblasting machine includes at least a fixing device 1, a positioning device 2, a plurality of sandblasting guns 3, and a high-pressure liquid supply system 6. Figure 1 As shown, the fixing device includes a first fixing seat 11 and a second fixing seat 12 arranged symmetrically. The first fixing seat and the second fixing seat are provided with coaxial slots 111 for the wire to pass through. These two coaxial slots 111 allow the wire to pass through smoothly. This design not only ensures the stability of the wire during the conveying process, but also provides a good foundation for subsequent sandblasting treatment.

[0030] Preferably, the first fixing seat 11 and the second fixing seat 12 are provided with a connecting bracket 112. The connecting bracket is used for external mounting and fixing of the first fixing seat and the second fixing seat.

[0031] like Figure 2 As shown, it also includes a fixing bracket 4, which includes a first fixing plate 41 and a second fixing plate 42 located between the first fixing seat and the second fixing seat. The first fixing plate and the first fixing seat are fixedly connected, and the second fixing plate and the second fixing seat are also fixedly connected. The first fixing plate and the second fixing plate are respectively provided with a second slot 411 that matches the first slot for wire passage. A plurality of mounting rods 43 are arranged at intervals along the circumferential direction between the first fixing plate and the second fixing plate. One end of the mounting rod is fixedly connected to the first fixing plate, and the other end is fixedly connected to the second fixing plate. In this embodiment, four mounting rods are provided, which are parallel and evenly spaced along the circumferential direction.

[0032] At least one mounting plate 44 is provided between the first fixing plate 41 and the second fixing plate 42 along the wire passing direction. The mounting plate is fixedly connected to the mounting rod, and a positioning device 2 is installed on either mounting plate. In this embodiment, a mounting plate 44 is provided between the first fixing plate 41 and the second fixing plate, forming a first sandblasting area 45 between the mounting plate and the first fixing plate, and a second sandblasting area 46 between the mounting plate and the second fixing plate. The first fixing plate and the second fixing plate serve as the core support parts of the sandblasting machine, and are firmly fixed on the first fixing seat and the second fixing seat. The mounting plate provided between them not only serves to connect and reinforce, but also cleverly divides the entire sandblasting area into two, forming the first sandblasting area and the second sandblasting area. This partitioned design allows the wire to pass through two different processing areas successively during continuous passage, achieving a more detailed and comprehensive sandblasting effect.

[0033] At least one positioning device 2 for radial positioning of the wire and several sandblasting guns 3 for surface treatment of the wire are provided at intervals between the first fixed seat and the second fixed seat along the wire passing direction.

[0034] like Figure 3 As shown, the positioning device 2 includes a sleeve 21 for accommodating the wire, a delivery pipe 22, and a fixed base 23 adapted to and connected to the sleeve. The sleeve has an internal cavity 211 that extends from front to back, and the outer wall of the sleeve is provided with a plurality of fluid flow holes 212 at intervals along the circumferential direction, which communicate with the cavity. One end of the delivery pipe is connected to the high-pressure fluid supply system 6, and the other end is connected to the fluid flow holes. The high-pressure fluid supply system 6 delivers high-pressure fluid to the cavity of the sleeve through the delivery pipe and the fluid flow holes, forming a radial force on the wire, thereby radially positioning and supporting the wire.

[0035] Preferably, the fixed base is provided with an inlet hole 231 that matches and communicates with the liquid flow hole, the delivery pipe is fixedly connected to the fixed base and communicates with the inlet hole, and the delivery pipe delivers high-pressure fluid to the cavity of the sleeve through the inlet hole and the liquid flow hole.

[0036] like Figures 4 to 5 As shown, the mounting base includes a side wall 232 and a top wall 233. The side wall and top wall together form an open-bottomed mounting cavity 234. One end of the sleeve is embedded in the mounting cavity and abuts against the side of the top wall closest to the mounting cavity. The top wall is provided with an outlet 235 that matches the cavity. The side wall extends outward to form a fixing part 236. Liquid inlet holes are located on the fixing part and are spaced apart along the circumferential direction. In this embodiment, the fixing part is evenly spaced with two liquid inlet holes. The two liquid inlet holes are symmetrically distributed at 180°, which facilitates sufficient and uniform entry of high-pressure water, applying uniform pressure to the outer wall surface of the sleeve, and avoiding the problem of damage to the seal between the sleeve and the mounting base due to uneven force on the sleeve and the mounting cavity of the mounting base.

[0037] A flow channel 237, formed by an outward indentation from the inner surface, is provided at the position corresponding to the inlet hole in the mounting cavity. The presence of the flow channel ensures that high-pressure water can adequately enter the cavity inside the sleeve. The water flow can be more easily concentrated and guided, thereby effectively filling the entire cavity and avoiding problems of water dispersion or insufficient flow. Due to the concave shape of the flow channel, the water flow is evenly distributed when entering the cavity, thus avoiding situations where the water flow is too concentrated in some areas or too sparse in others, while also avoiding noise problems.

[0038] The fixing part 236 extends outward from the end away from the top wall 233 to form a guide part 238. A conduit 2381, adapted to the outer wall surface of the sleeve 21, is provided within the guide part, and a chamfer is provided at the inlet of the conduit. Due to the presence of the guide part, the wire receives clear path guidance when passing through the sleeve. This helps ensure that the wire can smoothly enter the sleeve, reducing potential confusion or misalignment during the wire's passage. Secondly, the conduit within the guide part is adapted to the outer wall surface of the sleeve, meaning that the size and shape of the conduit are designed for a perfect match with the sleeve. This adaptability ensures that the friction and resistance between the sleeve and the conduit are reduced after the wire enters the sleeve. This design not only improves the efficiency of wire passage through the sleeve, but also significantly extends the service life of the sleeve for applications requiring frequent wire replacement, while also reducing replacement and maintenance costs.

[0039] like Figure 5 As shown, the fixing part 236 of the fixing base has a plurality of mounting holes 239 spaced along the circumferential direction on the side near the top wall 233. In this embodiment, there are 6 mounting holes for fixing the wire positioning device to the mounting plate 44.

[0040] like Figures 6 to 7As shown, the outer wall of the sleeve is adapted to the inner surface of the mounting cavity 234. The liquid flow hole penetrates the outer wall of the sleeve and is connected to the cavity of the sleeve. The liquid flow hole is connected to the liquid inlet hole 231 through the liquid flow groove 237. High-pressure water enters the inner cavity of the sleeve through the liquid inlet hole, the liquid flow groove and the liquid flow hole in sequence. The high-pressure water fills the gap between the wire and the sleeve. The high-pressure water cavity formed by the high water pressure can fix the position of the wire to the required working position, eliminate the shaking phenomenon of the wire during operation, and wash away the attached steel sand on the surface of the wire, avoiding the risk of steel sand scratching the wire.

[0041] In this embodiment, the sleeve is evenly spaced with three fluid flow holes 22 along its circumference, with an included angle of 120° between the holes. High-pressure water fills the gap between the wire and the sleeve through the fluid flow holes, creating a pressure greater than 0.4 MPa. This ensures that the wire is accurately positioned and does not vibrate during sandblasting.

[0042] like Figures 8 to 9 As shown, the sleeve is embedded in the mounting cavity, with one end abutting against the top wall 233 near the mounting cavity. The end of the sleeve away from the top wall 233 extends out of the guide portion 238. The size of the outlet 235 of the top wall is larger than the cross-sectional size of the sleeve cavity but smaller than the cross-sectional size of the outer wall of the sleeve. The inner surface size of the sleeve cavity is adapted to the outer surface size of the wire 5. The wire 5 and the sleeve cavity are in clearance fit to ensure that high pressure can enter the gap between the wire and the sleeve. The outlet 235 of the fixing seat in the positioning device 2 is the outlet for the wire to pass through the positioning device. When the positioning device is installed, the wire enters from the bottom opening of the fixing seat and exits from the outlet of the fixing seat, passing through the cavity of the sleeve located inside the fixing seat. This effectively ensures that the sleeve and the fixing seat are tightly abutted. This tight fit is the key to ensuring that the high pressure fluid can flow along a predetermined path, thereby ensuring that the high pressure fluid flows into the gap between the wire and the sleeve in sequence from the delivery pipe, the inlet hole, and the flow hole, and radially fixes the wire and axially sprays high pressure fluid. In this process, the fluid not only radially fixes the wire, ensuring it doesn't wobble or shift during operation, but also applies high-pressure jetting along the wire's axial direction. This jetting method not only improves fluid transfer efficiency but also helps clean and lubricate the wire, thereby further enhancing the overall system's reliability and lifespan.

[0043] like Figures 1 to 2 As shown, the positioning device 2 is mounted on the mounting plate through the mounting hole 237 on the fixing seat, and the outlet of the fixing seat is on the same axis as the slot hole. This design ensures that the wire maintains a straight trajectory when passing through these components, thereby avoiding fluid leakage or wire damage that may be caused by bending or twisting.

[0044] Four sandblasting guns 3 are staggered circumferentially in both the first sandblasting zone 45 and the second sandblasting zone 46. The sandblasting guns are mounted on mounting rods 43, with their nozzles close to the wire surface. This layout ensures effective coverage of the wire regardless of its location. Each sandblasting gun's nozzle is precisely designed and adjusted to ensure close proximity to the wire surface, guaranteeing uniformity and consistency in sandblasting. When the wire passes through the first sandblasting zone, its surface is first impacted by a ring of high-pressure sand. These high-speed rotating sand particles quickly remove dirt, oxide layers, and other unwanted deposits from the wire surface. Simultaneously, a positioning device on the mounting plate sprays high-pressure fluid to continuously flush the wire surface. This step not only removes residual sand and impurities but also pre-treats the wire surface before it enters the second sandblasting zone, making it cleaner and smoother. After treatment in the first sandblasting zone, the wire surface has undergone preliminary cleaning and finishing. When it enters the second sandblasting zone, it is again subjected to the impact and friction of the high-pressure sand stream, undergoing a more meticulous and in-depth sandblasting process. This secondary treatment further improves the surface finish and adhesion of the wire, enabling it to reach higher quality standards.

[0045] In summary, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
