Technical Field

[0001] This invention relates to the technical field, specifically to a rust removal process for the surface of steel wire rod. Background Technology

[0002] Steel wire rod is commonly used to manufacture various steel wire products, such as steel wire rope, steel wire mesh, and steel wire reinforcement. During processing, the steel wire rod needs to be derusted.

[0003] A Chinese patent with publication number CN201721138387 discloses a rebar rust removal machine, comprising a rust removal device, a rust removal wheel, rebar holes, a main shaft, a fixing block, lock holes, a base, an electrical control box, a controller, a power interface, a motor, an injector, a fan, a dust conveying pipe, and a dust collection box. The bottom of the injector is fixedly connected to the rust removal device. The main shaft is located at both the top and bottom of the rust removal device, penetrating the device. The rust removal wheel is connected to and movably connected to the surface of the main shaft. The right side of the rust removal device is fixedly connected to the fixing block at the top and bottom. The middle of the fixing block is fixedly connected to the main shaft. Lock holes are located at the four corners of the fixing block, penetrating the block. The upper right end of the base is fixedly connected to the rust removal device. This device uses a motor to drive the rust removal wheel to remove rust from the rebar. However, due to the high friction during the rust removal process, the rust removal wheel wears out quickly, resulting in severe wear after a short period of operation, significantly affecting the rust removal effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rust removal process for steel wire rod surfaces, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rust removal process for steel wire rod surfaces, comprising the following steps:

[0006] Step 1: Straighten the wire rod using rust removal equipment and break up the oxide layer;

[0007] Step 2: Loosen the oxide layer on the surface of the wire rod by tapping.

[0008] Step 3: Drive the conveyor belt to move back and forth, constantly changing position during the polishing process;

[0009] Step 4: Move the unworn conveyor belt above the wire rod for replacement;

[0010] Step 5: Use a wiping pad to scrape off the debris on the surface of the wire rod for cleaning, and then output the product to complete the rust removal process;

[0011] Step 6: Clean up the debris;

[0012] Step 7: After the conveyor belt wears out after a period of use, the double-rod drive cylinder drives the rotating motor to retract, which in turn drives the drive wheel to retract. At this point, the tension on the conveyor belt is lost. Then, the conveyor belt is removed and replaced. After that, the double-rod drive cylinder drives the two rotating motors to reset, tightening the conveyor belt and completing the replacement.

[0013] As a further aspect of the present invention: in step one, when straightening the wire rod, the wire rod is squeezed inside the conveying wheel by an extrusion wheel.

[0014] As a further aspect of the present invention: during the crushing process of the oxide layer in step one, the extrusion wheel and the conveying wheel extrude each other on the surface of the wire rod.

[0015] As a further aspect of the present invention: in step two, when the oxide layer on the surface of the wire rod is loosened by knocking, the motor drives the rotating disk to rotate continuously, and the surface of the wire rod is struck by the actuating rod.

[0016] As a further aspect of the present invention: In step three, when the conveyor belt moves back and forth, the rotating motor in the grinding assembly drives the drive shaft to rotate, the drive shaft rotates, drives the drive wheel to rotate, drives the conveyor belt to rotate, and drives the grinding surface to grind the side of the wire rod. During grinding, the motor drives the threaded rod to rotate, driving the sliding plate to slide on the surface of the fixed plate. When the sliding plate slides on the surface of the fixed plate, it is guided by the slider sliding in the sliding groove, and the sliding plate moves.

[0017] As a further aspect of the present invention: when replacing the unworn conveyor belt in step four, the motor drives the threaded rod to rotate, which drives the sliding plate to slide on the surface of the fixed plate. When the sliding plate slides on the surface of the fixed plate, it is guided by the slider sliding in the sliding groove. The movement of the sliding plate causes the conveyor belt to extend.

[0018] As a further aspect of the present invention: two grinding components are provided, and they are staggered on both sides of the wire rod.

[0019] As a further aspect of the present invention: in step six, when cleaning debris, air is blown out using a blower and then collected through a debris collection box.

[0020] The rust removal equipment includes a fixed frame, on the surface of which a conveying wheel and a pressing wheel are rotatably connected. The conveying wheel has an inner groove for conveying wire rod. The width of the pressing wheel is smaller than the inner diameter of the groove. The pressing wheel compresses the wire rod within the conveying wheel, straightening it and breaking up the oxide layer on the wire rod surface through the initial compression of the pressing and conveying wheels. A rotating disk is rotatably connected to the surface of the fixed frame, and a lever made of rubber is fixedly connected to one side of the rotating disk. The rotating disk is driven by a motor to rotate continuously, and the lever strikes the surface of the wire rod, loosening the oxide layer. A grinding assembly is provided on the surface of the fixed frame, including components fixed to one side of the fixed frame. A fixed plate has a sliding plate movably connected to its surface. A slider is fixedly connected to one side of the sliding plate, and one side of the slider penetrates the surface of the fixed plate and extends into the inner cavity of the fixed plate. The inner cavity of the fixed plate has a sliding groove that slides with the surface of the slider. A threaded rod driven by a motor is rotatably connected to the surface of the fixed plate. A connecting plate threaded with the surface of the threaded rod is fixedly connected to the bottom of the sliding plate. A double-rod drive cylinder is fixedly connected to the surface of the sliding plate. A rotary motor is fixedly connected to one end of each of the two piston rods of the double-rod drive cylinder. A drive shaft is fixedly connected to the output shaft of the rotary motor via a coupling. A drive wheel is fixedly connected to the surface of the drive shaft, and a conveyor belt is driven to the surface of the drive wheel. The conveyor belt has a polishing surface. During operation, a motor drives a drive shaft to rotate, which in turn rotates a drive wheel, causing the conveyor belt to rotate and polishing the sides of the wire rod. Simultaneously, the motor drives a threaded rod to rotate, causing a sliding plate to slide on the surface of a fixed plate. This sliding plate is guided by a slider within a sliding groove. The movement of the sliding plate causes the conveyor belt to move back and forth in small amplitudes, continuously changing position during polishing. This enhances the polishing effect and effectively reduces wear on the polishing surface of the conveyor belt. Multiple conveyor belts can polish all four sides of the wire rod. Furthermore, once wear occurs on the polishing surface of one conveyor belt, the motor drives the threaded rod to rotate again, causing the... The sliding plate slides on the surface of the fixed plate. As it slides, it is guided by a slider sliding within a sliding groove. The movement of the sliding plate causes the conveyor belt to extend, moving a non-wearing conveyor belt above the wire rod for replacement and re-grinding. This eliminates the need for frequent machine stops. A connecting block is fixedly connected to one side of the fixed frame, and a connecting rod is fixedly connected to the bottom of the connecting block. A wiping pad is slidably connected to the bottom of the connecting rod. The inner cavity of the wiping pad has an adapter groove that slidably connects to the surface of the connecting rod. A return spring is fitted onto the surface of the connecting rod. One end of the return spring is fixedly connected to one side of the connecting block, and the other end is fixedly connected to the surface of the wiping pad. During use, the wiping pad remains in contact with the surface of the wire rod.The wire rod is wiped, and a return spring continuously applies pressure to the wiping pad, pressing it against the surface of the wire rod. The wiping pad scrapes off debris from the wire rod surface for cleaning, and then the rust removal process is complete. The surface of the fixed frame is equipped with an air blower and a debris collection box. Air is blown out by the air blower and collected in the debris collection box.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This invention continuously changes position during grinding, which enhances the grinding effect while effectively reducing wear on the grinding surface of the conveyor belt. Furthermore, after the grinding surface of one conveyor belt becomes worn, an unworn conveyor belt can be moved above the wire rod for replacement and re-grinding. This eliminates the need for frequent machine downtime and waiting, allowing for quick replacement and improving processing efficiency.

[0023] 2. In this invention, by setting a reset spring, a continuous pushing force is applied to the wiping pad, causing it to press against the surface of the wire rod. The wiping pad scrapes off the debris on the surface of the wire rod for cleaning, and then outputs the finished product to complete the rust removal process. Attached Figure Description

[0030] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0031] Please see Figure 1-5 This invention provides a technical solution: a rust removal process for the surface of steel wire rod, comprising the following steps:

[0032] Step 1: The wire rod is squeezed by the extrusion roller 3 inside the conveyor roller 2 to straighten it, and the oxide layer on the surface of the wire rod is broken by the initial extrusion of the extrusion roller 3 and the conveyor roller 2.

[0033] Step 2: The motor drives the rotating disk 15 to rotate continuously, and the actuating lever 16 strikes the surface of the wire rod to loosen the oxide layer on its surface.

[0034] Step 3: The rotating motor 8 drives the drive shaft 11 to rotate, which in turn drives the drive wheel 12 to rotate, which in turn drives the conveyor belt 13 to rotate, which in turn drives the grinding surface 14 to grind the side of the wire rod. During grinding, the motor drives the threaded rod 10 to rotate, which drives the sliding plate 7 to slide on the surface of the fixed plate 4. When the sliding plate 7 slides on the surface of the fixed plate 4, it is guided by the slider 6 sliding in the sliding groove 5. The movement of the sliding plate 7 drives the conveyor belt 13 to make small back-and-forth movements, and the position changes continuously during the grinding process.

[0035] Step 4: The motor drives the threaded rod 10 to rotate, which drives the sliding plate 7 to slide on the surface of the fixed plate 4. When the sliding plate 7 slides on the surface of the fixed plate 4, it is guided by the slider 6 sliding in the sliding groove 5. The movement of the sliding plate 7 drives the conveyor belt 13 to extend and move the unworn conveyor belt 13 to the top of the wire rod for replacement.

[0036] Step 5: The wiping pad 20 is placed against the surface of the wire rod to wipe it. The return spring 19 continuously applies a pushing force to the wiping pad 20, pressing it against the surface of the wire rod. The wiping pad 20 scrapes off the debris on the surface of the wire rod for cleaning, and then outputs the product to complete the rust removal process.

[0037] In step one, when straightening the wire rod, the wire rod is squeezed inside the conveyor wheel 2 by the extrusion wheel 3.

[0038] In step one, when the oxide layer is crushed, the extrusion roller 3 and the conveyor roller 2 extrude each other on the surface of the wire rod.

[0039] In step two, when the oxide layer on the surface of the wire rod is loosened by tapping, the motor drives the rotating disk 15 to rotate continuously, and the surface of the wire rod is struck by the actuating rod 16.

[0040] In step three, when the conveyor belt 13 moves back and forth, the rotating motor 8 in the grinding assembly drives the drive shaft 11 to rotate. The rotation of the drive shaft 11 drives the drive wheel 12 to rotate, which in turn drives the conveyor belt 13 to rotate. This causes the grinding surface 14 to grind the side of the wire rod. During grinding, the motor drives the threaded rod 10 to rotate, which drives the sliding plate 7 to slide on the surface of the fixed plate 4. When the sliding plate 7 slides on the surface of the fixed plate 4, it is guided by the slider 6 sliding in the sliding groove 5.

[0041] In step four, when replacing the unworn conveyor belt 13, the motor drives the threaded rod 10 to rotate, which drives the sliding plate 7 to slide on the surface of the fixed plate 4. When the sliding plate 7 slides on the surface of the fixed plate 4, it is guided by the slider 6 sliding in the sliding groove 5. The movement of the sliding plate 7 causes the conveyor belt 13 to extend.

[0042] There are two grinding components, which are staggered on both sides of the wire rod.

[0043] In step six, when cleaning up debris, air is blown out through the blower 23 and then collected through the debris collection box 22.

[0044] The rust removal equipment includes a fixed frame 1. A conveyor wheel 2 and a pressing wheel 3 are rotatably connected to the surface of the fixed frame 1. The inner cavity of the conveyor wheel 2 has an inner groove for conveying the wire rod. The width of the pressing wheel 3 is smaller than the inner diameter of the inner groove. The pressing wheel 3 presses the wire rod within the conveyor wheel 2, straightening it. The initial pressing by the pressing wheel 3 and the conveyor wheel 2 also breaks up the oxide layer on the surface of the wire rod. A rotating disk 15 is rotatably connected to the surface of the fixed frame 1. A lever 16, made of rubber, is fixedly connected to one side of the rotating disk 15. The rotating disk 15 is driven by a motor to rotate continuously, and the lever 16 strikes the surface of the wire rod, loosening the oxide layer. A grinding assembly is also provided on the surface of the fixed frame 1. The system includes a fixed plate 4 fixed to one side of a fixed frame 1. A sliding plate 7 is movably connected to the surface of the fixed plate 4. A slider 6 is fixedly connected to one side of the sliding plate 7.

This causes the grinding surface 14 to grind the side of the wire rod. During grinding, the threaded rod 10 is driven by the motor to rotate, causing the sliding plate 7 to slide on the surface of the fixed plate 4. The sliding plate 7 is guided by the slider 6 sliding within the sliding groove 5.

This enhances the grinding effect and effectively reduces wear on the grinding surface 14 of the conveyor belt 13. Multiple conveyor belts are also included. The conveyor belt 13 can grind all four sides of the wire rod. After the grinding surface 14 on one of the conveyor belts 13 becomes worn, the threaded rod 10 is driven by the motor to rotate, which drives the sliding plate 7 to slide on the surface of the fixed plate 4. When the sliding plate 7 slides on the surface of the fixed plate 4, it is guided by the sliding slider 6 sliding in the sliding groove 5. The movement of the sliding plate 7 drives the conveyor belt 13 to extend, and moves the unworn conveyor belt 13 to the top of the wire rod for replacement and re-grinding. There is no need to stop the machine frequently. A connecting block 17 is fixedly connected to one side of the fixed frame 1.

One end of the return spring 19 is fixedly connected to one side of the connecting block 17, and the other end of the return spring 19 is fixedly connected to the surface of the wiping pad 20. During use, the wiping pad 20 is always in contact with the surface of the wire rod to wipe the wire rod. The return spring 19 continuously applies a pushing force to the wiping pad 20, pressing it against the surface of the wire rod. The wiping pad 20 scrapes off the debris on the surface of the wire rod for cleaning, and then outputs the rust removal. The surface of the fixed frame 1 is respectively equipped with a blower 23 and a debris collection box 22. The blower 23 blows air out and then collects it through the debris collection box 22.
