Abstract
Description
Technical Field
[0001] This application relates to the field of metal wire production equipment technology, and in particular to a wire-rolling device for high-speed wire rolling. Background Technology
[0002] High-speed wire rod mills generally refer to wire rod mills with a maximum rolling speed exceeding 40 m / s. They are a product of the integration of metallurgical technology, electrical control technology, and mechanical manufacturing technology. On a high-speed wire rod production line, after rolling, the wire needs to be coiled by a coiler to complete the transformation from straight wire to coiled wire. The coiler is one of the key pieces of equipment in high-speed wire rod production.
[0003] The wire spinning machine is typically a horizontal structure located behind the finishing mill. It consists of a transmission device, hollow shaft, spinning disc, spinning tube, bevel gears, and other components. During operation, the wire is fed into the hollow shaft of the spinning machine through the pinch rollers at the inlet. The hollow shaft drives the spinning disc and spinning tube to rotate together, causing the wire entering the hollow shaft to be extruded as a coil along the tangential direction of the spinning tube's outlet circumference. The coil is then smoothly deposited onto the air-cooled roller conveyor, forming a continuous coil. As the wire passes through the high-speed rotating spinning tube, it is subjected to the normal pressure of the tube wall, sliding friction, the thrust of the finishing mill and pinch rollers, and its own centrifugal force. As the wire gradually bends and deforms with the shape of the spinning tube, it transitions from linear motion to bending, reaching the required curvature at the outlet of the spinning tube, forming a spiral coil. The coil is then evenly and smoothly extruded as a coil falls onto the roller conveyor, where it is transported to the next processing equipment using the rollers.
[0004] The temperature of the wire exiting the wire spinning machine is typically as high as 850-1000℃. To suppress excessive grain growth in the metal wire, refine the microstructure, and thus improve the wire's strength, toughness, and other mechanical properties, a dedicated fan is usually installed above the roller conveyor to cool the metal wire using the airflow generated by the fan. To ensure smooth airflow over the wire on the roller conveyor, relatively large gaps are usually provided between the different conveyor rollers. However, when the end of the wire is ejected from the spinning machine, it can easily get stuck in the gaps between the conveyor rollers. This requires workers near the equipment to use iron hooks to promptly remove the wire, which not only increases the workers' workload but also poses a risk of injury from the high-temperature wire if not handled carefully. Utility Model Content
[0005] This application provides a wire-spinning device for high-speed wire rod rolling, which can temporarily block part of the roller gap near the exit of the wire rod main body during the early stage of wire spinning, thereby preventing the end of the metal wire from getting stuck. This saves workers the trouble of dealing with stuck metal wire and avoids some problems caused by it.
[0006] The above-mentioned objective of this application is achieved through the following technical solution:
[0007] A high-speed wire rod rolling device includes a wire rod spinning machine body, and a roller conveyor is provided at the outlet of the wire rod spinning machine body, wherein there is a gap between adjacent conveying rollers in the roller conveyor.
[0008] A temporary sealing mechanism is provided below the roller conveyor near the main body of the spinning machine. The temporary sealing mechanism can temporarily seal the gap between the conveyor rollers near the main body of the spinning machine.
[0009] The temporary sealing mechanism includes a mounting base, and a sealing module is provided above the mounting base. The sealing module is connected to the mounting base via a height adjustment component.
[0010] Furthermore, the sealing module includes a top support platform, above which a grid frame is arranged in parallel. The grid frame and the top support platform are fixedly connected by multiple support rods. The crossbars in the grid frame along the width direction of the roller conveyor are all located at the top, and the distance between adjacent crossbars in the grid frame is equal to the gap distance between adjacent conveying rollers in the roller conveyor. A sealing crossbar is installed above each crossbar in the grid frame.
[0011] Furthermore, the blocking crossbar is a cylindrical rod, the diameter of which is equal to the gap between two adjacent conveyor rollers. Both ends of the blocking crossbar are fixedly connected to an end shaft, and a support bracket is movably sleeved on each of the two end shafts. The lower end of the support bracket is fixedly connected to the grid frame crossbar at the corresponding position.
[0012] Furthermore, the height adjustment assembly includes an electric cylinder, the lower end of which is fixedly mounted on the mounting base, and the upper end of which is fixedly connected to the center point of the lower side of the top support platform. The mounting base is also provided with a control button, which is electrically connected to the electric cylinder.
[0013] Furthermore, the height adjustment assembly also includes four telescopic rods, which are located at the four corners of the space between the top support platform and the mounting base, and the lower ends of the outer sleeves of the telescopic rods are all fixedly connected to the mounting base, and the upper ends of the movable inner rods of the telescopic rods are all fixedly connected to the top support platform.
[0014] Furthermore, a side baffle is fixedly installed on each side of the roller conveyor in the width direction, and the height of the side baffle near the main body of the spinning machine is higher than the height of the other end.
[0015] Furthermore, a portal frame is installed on the outer side of the outlet of the main body of the spinning machine, and metal protective netting is fixedly installed on all sides of the portal frame.
[0016] Furthermore, the legs of the portal frame are fixedly connected to the roller conveyor frame on the adjacent side by a number of reinforcing rods.
[0017] In summary, this application includes at least one of the following beneficial technical effects:
[0018] This application includes a temporary blocking mechanism located below the roller conveyor near the outlet of the spinning machine. When the spinning machine is about to eject the metal wire, the height adjustment component in the temporary blocking mechanism is activated, raising the blocking module to a height close to the conveyor rollers in the roller conveyor. At this time, the blocking module can temporarily block the gap between some of the conveyor rollers near the outlet of the spinning machine. After the spinning machine ejects the end of a section of the metal wire, the metal wire will be difficult to get stuck in the gap between the conveyor rollers because the gap near the spinning machine is blocked. This eliminates the need for workers to use hooks to pull the metal wire out of the gap between the conveyor rollers, and the potential safety hazards associated with this operation are effectively resolved.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0027] like Figures 1-4 As shown, this application discloses a high-speed wire rod rolling device, which includes a wire rod spinning machine body 1, a roller conveyor 2 at the outlet of the wire rod spinning machine body 1, and gaps between adjacent conveying rollers 3 in the roller conveyor 2.
[0028] A temporary sealing mechanism 4 is provided below one end of the roller conveyor 2 near the main body 1 of the spinning machine. The temporary sealing mechanism 4 can temporarily seal the gap between some of the conveyor rollers 3 near the main body 1 of the spinning machine.
[0029] The temporary sealing mechanism 4 includes a mounting base 41, and a sealing module 42 is provided above the mounting base 41. The sealing module 42 is connected to the mounting base 41 through a height adjustment component 43.
[0030] In the above embodiments, when the wire spinning machine body 1 spits out the metal wire, since the end of the metal wire is the first part of the metal wire to come out, its front end does not have the wire part that has already fallen on the roller conveyor 2 for guidance, unlike the subsequent wire part. Therefore, the end of the metal wire that comes out first is easily thrown into the gap between the adjacent conveyor rollers 3 in the roller conveyor 2 by the wire spinning machine.
[0031] This application installs a temporary sealing mechanism 4 below the roller conveyor 2 near the outlet of the main body 1 of the spinning machine. The sealing module 42 at the uppermost end of the temporary sealing mechanism 4 can temporarily seal the gaps between the conveyor rollers 3 where the end of the metal wire may enter. This can effectively prevent the end of the metal wire discharged from the outlet of the main body 1 of the spinning machine from getting stuck in the gaps between the conveyor rollers 3.
[0032] In actual use, when the worker observes that the main body 1 of the wire spinning machine is about to eject the metal wire, they can activate the height adjustment component 43 in the temporary sealing mechanism 4 to raise the sealing module 42 to a height close to the conveyor rollers 3 in the roller conveyor 2. At this time, the sealing module 42 can temporarily seal the gap between the conveyor rollers 3 near the outlet of the main body 1 of the wire spinning machine. In this way, after the main body 1 of the wire spinning machine ejects the end of a section of metal wire, the metal wire will be difficult to get stuck in the gap between the conveyor rollers 3 because the gap near the main body 1 of the wire spinning machine is blocked. This saves the worker the trouble of using a hook to pull the metal wire out of the gap between the conveyor rollers 3, and the potential safety hazards of this operation are also effectively solved. When the metal wire forms a stable coil on the roller conveyor 2, the sealing module 42 can be lowered by the height adjustment component 43. In this way, the cold air blown by the fan to the roller conveyor 2 can freely pass through the gap between the conveyor rollers 3 again to uniformly cool the metal wire. In addition, when the main body 1 of the wire spinning machine spits out the end of the metal wire, the tail of the metal wire is prone to coil tailing phenomenon. At this time, the metal wire is also easy to get stuck in the gap between the conveyor rollers 3. At this time, the worker can also use the height adjustment component 43 to temporarily block the conveyor rollers 3 near the outlet of the main body 1 of the wire spinning machine before the tail of the metal wire is spouted out, so as to reduce the risk of the tail of the metal wire getting stuck in the gap between the conveyor rollers 3.
[0033] Furthermore, such as Figures 1-5 As shown, the blocking module 42 includes a top support platform 421, and a grid frame 422 is arranged parallel above the top support platform 421. The grid frame 422 and the top support platform 421 are fixedly connected by multiple support rods 423. The crossbars in the grid frame 422 along the width direction of the roller conveyor 2 are all located at the top, and the distance between adjacent crossbars in the grid frame 422 is equal to the gap distance between adjacent conveying rollers 3 in the roller conveyor 2. A blocking crossbar 424 is installed above each crossbar in the grid frame 422.
[0034] In the above embodiments, the lower side of the support platform is connected to the height adjustment component 43. During operation, the height adjustment component 43 provides a uniform and stable driving force to the grille frame 422 through the support platform. Figure 5As shown, the grid frame 422 of this application is welded from multiple intersecting metal square tubes. The longitudinal square tubes along the direction of metal wire movement are located below the crossbars along the width direction of the roller conveyor 2, and the number of crossbars is equal to the number of gaps between the conveyor rollers 3 that need to be blocked. Thus, after a blocking crossbar 424 is installed on each crossbar, when the support platform lifts the multiple blocking crossbars 424 through the grid frame 422, the gaps between the conveyor rollers 3 that may jam the metal wire can be quickly blocked by the multiple blocking crossbars 424.
[0035] Furthermore, such as Figure 4 and Figure 5 As shown, the blocking crossbar 424 is a cylindrical rod. The diameter of the blocking crossbar 424 is equal to the gap between two adjacent conveyor rollers 3. Both ends of the blocking crossbar 424 are fixedly connected to an end shaft 5. A support bracket 6 is movably sleeved on each of the two end shafts 5. The lower end of the support bracket 6 is fixedly connected to the crossbar of the grid frame 422 at the corresponding position.
[0036] In the above embodiments, since the conveying rollers 3 in the roller conveyor 2 rotate continuously during operation, if the blocking crossbar 424 of this application is a fixed structure, it can easily affect the normal rotation of the conveying rollers 3 when it comes into contact with them during the blocking process. Therefore, this application movably mounts the blocking crossbar 424 on the support bracket 6 through the end shafts 5 at both ends. In this way, when the blocking crossbar 424 blocks the gap between the conveying rollers 3, even if it comes into contact with the conveying rollers 3, it will convert the resistance to the conveying rollers 3 into rolling friction, which can reduce the impact of the blocking crossbar 424 on the conveying rollers 3 during the blocking process.
[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the height adjustment component 43 includes an electric cylinder 431. The lower end of the electric cylinder 431 is fixedly mounted on the mounting base 41, and the upper end of the electric cylinder 431 is fixedly connected to the center point of the lower side of the top support platform 421. The mounting base 41 is also provided with a control button 432, which is electrically connected to the electric cylinder 431.
[0038] In the above embodiments, the electric cylinder 431 is also called an electric cylinder. The reason why the electric cylinder 431 is chosen as the core of the height adjustment component 43 in this application is because the electric cylinder 431 directly controls the speed through current input, supports full-stroke proportional adjustment, has a fast response speed and strong stability, and does not require hydraulic oil or compressed air, thus avoiding oil leakage and environmental pollution. In addition, the electric cylinder 431 of this application can be connected to the control room of the metal wire through a circuit, so it can be directly controlled by electronic signals. If the manufacturing enterprise adopts an automated production system, the electric cylinder 431 can also be well integrated.
[0039] Furthermore, such as Figure 3 and Figure 4 As shown, the height adjustment assembly 43 also includes four telescopic rods 433, which are located at the four corners of the space between the top support platform 421 and the mounting base 41. The lower ends of the outer sleeves of the telescopic rods 433 are all fixedly connected to the mounting base 41, and the upper ends of the movable inner rods of the telescopic rods 433 are all fixedly connected to the top support platform 421.
[0040] In the above embodiments, the electric cylinder 431, located at the center of the space between the top support platform 421 and the mounting base 41, serves as the core power source, enabling high-precision positioning and dynamic response, and meeting the precise control requirements for the lifting height and speed of multiple blocking crossbars 424. The installation of telescopic rods 433 at the four corners of the space between the top support platform 421 and the mounting base 41 improves the overall structural stability through multi-point force distribution, reducing swaying during lifting.
[0041] Furthermore, such as Figure 1 As shown, a side baffle 7 is fixedly installed on each side of the roller conveyor 2 in the width direction, and the height of the side baffle 7 near the main body 1 of the spinning machine is higher than the height of the other end.
[0042] In the above embodiments, the side baffles 7 provided on both sides of the roller conveyor 2 in the width direction can play a certain role in isolating and protecting the metal wire on the roller conveyor 2. The side baffle 7 near the outlet of the spinning machine body 1 is set to be higher than the other end because when the metal wire is ejected from the spinning machine body 1, there will be a certain drop height, and the high-temperature impurities on the metal wire may splash in all directions. By increasing the height of the side baffle 7 near the outlet of the spinning machine body 1, these high-temperature splashes can be blocked to a certain extent.
[0043] Furthermore, such as Figures 1-3 As shown, a portal frame 8 is installed on the outer side of the outlet of the main body 1 of the spinning machine, and metal protective nets 9 are fixedly installed on all sides of the portal frame 8.
[0044] In the above embodiments, during the spinning process, the wire may break due to uneven cooling or loss of tension. When it swings at high speed, it can easily injure the operator. The gate-shaped bracket 8 set at the outlet of the spinning machine body 1 can temporarily intercept the metal wire in such a sudden situation through the metal protective net 9 around it, thereby giving the operator some time to take emergency measures.
[0045] Furthermore, such as Figure 1 and Figure 2 As shown, the legs of the portal frame 8 are fixedly connected to the frame of the roller conveyor 2 on the adjacent side by multiple reinforcing rods 10.
[0046] In the above embodiments, since the roller conveyor 2 part near the main body 1 of the spinning machine will be subjected to a certain impact force from the falling metal wire during use, the stability requirements of this part of the roller conveyor 2 during use will be higher. Based on this, this application further connects this part of the roller conveyor 2 to the gantry bracket 8 through the reinforcing rod 10. This not only improves the overall integrity of the entire equipment, but also improves the stability of the part of the roller conveyor 2 that first receives the wire.
[0047] The implementation principle of this embodiment is as follows: When the main body 1 of the spinning machine is about to eject the metal wire, the electric cylinder 431 in the temporary sealing mechanism 4 is activated, raising the multiple sealing crossbars 424 in the sealing module 42 to a height close to the conveying roller 3 in the roller conveyor 2. At this time, the multiple sealing crossbars 424 can temporarily seal the gap between the conveying rollers 3 near the outlet of the main body 1 of the spinning machine. In this way, when the main body 1 of the spinning machine ejects the end of a section of the metal wire in the future, the metal wire will be difficult to get stuck in the gap between the conveying rollers 3 because the gap near the main body 1 of the spinning machine is blocked. This saves workers the trouble of using hooks to pull the metal wire out of the gap between the conveying rollers 3, and the safety hazard that may be caused by performing this operation can also be effectively solved. When the metal wire forms a stable coil on the roller conveyor 2, the electric cylinder 431 can be operated again to lower the entire sealing module 42. In this way, the cold air blown by the fan to the roller conveyor 2 can freely pass through the gap between the conveyor rollers 3 again to uniformly cool the metal wire.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
