Description

Technical Field

[0001] This invention relates to the field of metal polishing technology, and more specifically to a workpiece rust removal device. Background Technology

[0002] When producing metal workpieces in batches, a large amount of coiled metal raw material is often used. However, due to the relatively enclosed storage space and susceptibility to corrosion from humid, acidic, and alkaline environments during transportation, rusting is a common occurrence. If rust removal and polishing are not carried out promptly, it will cause a series of serious problems for subsequent production and use.

[0003] From a processing technology perspective, the uneven surface and inconsistent texture of rusted coiled metal raw materials can interfere with the uniform deformation of the metal during rolling, stretching, and stamping operations. This can lead to decreased processing accuracy and even equipment jamming, mold wear, and other malfunctions, affecting production efficiency and equipment lifespan. For example, in the stamping process of automotive steel sheets, rust can cause indentations and cracks on the steel sheet surface, reducing the product qualification rate.

[0004] In terms of product quality, residual rust can affect the adhesion of surface treatment processes such as coatings and platings. Even if surface treatment is barely completed, the rust will gradually spread outward over time, causing coatings to peel off and platings to corrode, severely impacting the product's appearance and protective performance. For coiled metal raw materials used in appliance casings, this phenomenon will significantly reduce the product's market competitiveness.

[0005] From a safety perspective, rust weakens the mechanical properties of metallic materials and reduces their load-bearing capacity. Taking coiled steel used in bridge construction and building structures as an example, if rust is not removed after rusting, it can easily lead to structural failure under long-term loads, threatening life and property safety. Furthermore, failure to promptly remove rust can cause companies to frequently replace raw materials, increase equipment maintenance costs, and even cause greater economic losses due to production interruptions.

[0006] Chinese patent document CN213561824U discloses a steel strip polishing and fixing device. The produced strip inevitably has burrs and flash on its surface, thus requiring a fine polishing device to polish the surface to meet production requirements. Because the strip has a long, thin strip structure, it is prone to vibration when entering the fine polishing device. This vibration makes it difficult to remove burrs and flash, resulting in often unsatisfactory polishing results.

[0007] Since metal raw materials are usually stored in rolls, they may bend. Before production and processing, the raw materials need to be polished to give them better physical properties. However, due to the special nature of metal strips, conventional fixing devices cannot hold them stably during polishing, causing vibrations that result in insufficient polishing precision. Furthermore, different types of raw materials, as well as variations in width and thickness, make it difficult to achieve consistent polishing at the edges of the strips, which can easily lead to defective products during subsequent batch processing. Summary of the Invention

[0008] This invention provides a workpiece rust removal device, which aims to solve the technical problems in related technologies where metal raw materials are generally stored in rolls, causing the raw materials to bend. During grinding, conventional fixing devices cannot hold the raw materials stably, and vibration is prone to occur during grinding, resulting in different polishing precision. Furthermore, due to differences in the type, width, and thickness of the raw materials, it is difficult to achieve a consistent polishing degree on the edges of the material.

[0009] A workpiece rust removal device of the present invention includes a frame, a feeding roller disposed on the left side of the frame and a receiving roller disposed on the right side of the frame, and further includes: at least two positioning mechanisms, the two positioning mechanisms being installed in the frame and staggered from each other in the left-right direction, each positioning mechanism including a magnet for adsorbing the material and two positioning parts mounted on the magnet for clamping the two sides of the material, the two magnets being slidably installed in the frame and respectively located on the upper and lower sides of the material, a groove being provided on the side of the magnet near the material, the two positioning parts being symmetrically disposed on the magnet and sliding in the front-back direction, a polishing mechanism being installed on the side of the magnet near the material, the polishing mechanism including a polishing rod and two conical blocks respectively slidably installed at both ends of the polishing rod, the polishing rod being rotatably disposed in the groove, and a part of the polishing rod protruding from the groove.

[0010] Its effect is as follows: During polishing of metal strips, the magnets attract and stably adhere the strip to the working surface. A combined polishing mechanism is housed within a special groove machined into the magnet surface. This mechanism includes a rotatable polishing rod and a guiding conical block, which work synergistically to uniformly treat the strip surface. During polishing, the continuous attraction of the magnets to the sides of the groove creates dynamic constraints, effectively suppressing mechanical vibrations generated by the strip and ensuring consistent surface treatment. A specially designed positioning mechanism achieves precise control of the strip's trajectory through force balance, ensuring the polishing wheel maintains constant contact pressure across the strip's width, fundamentally preventing one-sided over-grinding caused by material displacement.

[0011] Preferably, the end face of the magnet that is in close contact with the strip is provided with a groove. When the strip moves relative to the magnet, the groove collects the remaining impurities on the strip. The effect is that, by utilizing the magnetic attraction of the magnet, the groove can collect the remaining impurities on the surface of the strip, such as rust debris and polishing dust, during the movement of the strip, so as to avoid the impurities remaining and affecting subsequent processing or causing secondary scratches on the surface of the strip, thereby improving the polishing quality and product qualification rate.

[0012] Preferably, both ends of the polishing rod are provided with grooves arranged in a circumferential array, and the inner hole of the conical block is provided with convex strips arranged in a circumferential array. The grooves and convex strips slide in cooperation. The effect is that the sliding cooperation between the grooves and convex strips allows the conical block to slide on the polishing rod in the front-back direction, adapting to strips of different widths. At the same time, the circumferential cooperation of the two ensures that the conical block and the polishing rod rotate synchronously, ensuring the uniformity and consistency of the polishing of the strip edge, solving the problem of inconsistent edge polishing of different types of raw materials. The array of grooves and convex strips increases the contact area, improves the stability of the conical block during the sliding process, and avoids the decrease in polishing accuracy caused by loosening during polishing.

[0013] Preferably, the positioning component further includes a spring telescopic rod, a support ring, a rotating wheel, and a second telescopic drive assembly. One end of the second telescopic drive assembly is fixedly connected to a magnet, and the other end is fixedly connected to the support ring, driving the support ring to move in the front-back direction. One end of the telescopic rod is fixedly connected to the support ring, and the other end is fixed with a rotating wheel. In the initial state, the rotating wheel is closer to the strip material relative to the conical block, and the support ring abuts against the tail end of the conical block. The effect is that the second telescopic drive assembly can adjust the position of the support ring according to the width of the strip material. The spring telescopic rod provides flexible clamping force, making the rotating wheel closely adhere to the front and rear side walls of the strip material. This can stably clamp strip materials of different widths and avoid damage to the strip material caused by rigid clamping. The support ring abuts against the tail end of the conical block, and while positioning the strip material, it can push the conical block to adjust its position, so that the positioning component and the polishing mechanism form a linkage, further ensuring the positional accuracy of the strip material during the polishing process and solving the problem of unstable clamping caused by different widths.

[0014] Preferably, one end face of the support ring abuts against the bottom surface of the conical block, and a ball bearing is provided on its end face. The effect is that the ball bearing significantly reduces the frictional resistance between the support ring and the conical block, making the conical block move more smoothly relative to the support ring, ensuring stable rotation of the conical block during polishing, so as to achieve a better polishing effect and reduce frictional resistance so that the equipment can operate more stably.

[0015] Preferably, a flexible cloth is provided on the surface where the magnet and the strip are in close contact. The effect of this is that the flexible cloth can reduce the friction between the magnet and the strip, prevent the magnet surface from scratching the strip, and ensure the surface quality of the strip. At the same time, the flexible cloth can wipe the surface of the strip during the movement of the strip, further clean impurities, and improve the polishing effect. The flexible cloth reduces the moving friction between the magnet and the strip, which helps to improve the stability of the magnet adsorbing the strip and reduce the shaking of the strip during polishing.

[0016] Preferably, the magnet is an electromagnet, which has the advantage that: by setting the magnet as an electromagnet with adjustable magnetic force, when it is necessary to clean the debris on the surface of the magnet, the debris can be cleaned quickly by adjusting the magnetic force.

[0017] Preferably, a telescopic drive assembly is installed on the frame. One end of the telescopic drive assembly is fixed to the frame, and the other end is fixed to a magnet. The magnet is controlled to slide vertically on the frame. The effect is that the telescopic drive assembly can precisely adjust the position of the magnet in the vertical direction according to the thickness of the strip, ensuring that the magnet and the strip maintain a suitable adsorption pressure, adapting to the polishing requirements of strips of different thicknesses, and solving the problem of loose or excessive clamping caused by thickness differences. By driving the magnet to slide up and down, it is convenient to load and unload the strip and to maintain and repair the device, improving the convenience of production operation. To prevent instability during the up and down movement of the magnet, a telescopic drive assembly can also be set on the other side of the magnet to increase the stability of the device operation.

[0018] Preferably, the polishing mechanism includes a rotary drive assembly mounted on a magnet, the output end of which is connected to a polishing rod. The effect is that by setting the rotary drive assembly, the polishing rod can be driven to rotate at high speed, so as to perform efficient and uniform polishing on the surface of the material, thereby improving polishing efficiency and quality.

[0019] Preferably, the rotating wheel surface is fitted with a flexible ring, which has the following effects: the flexible ring is made of soft material, which can prevent the rotating wheel from scratching the surface of the strip; at the same time, the flexible ring increases the friction between the rotating wheel and the strip, making the positioning more stable, effectively suppressing the displacement of the strip in the front and back directions, further improving the polishing accuracy; the flexible ring has a certain degree of elasticity, which can buffer the small vibrations of the strip during the polishing process, reduce the polishing errors caused by vibration, and improve the stability of the polishing quality.

[0020] Beneficial effects:

[0021] 1. This device achieves dual stability of the material during polishing through a synergistic adsorption structure of a magnet and a groove, combined with the dynamic impurity collection function of the groove. The uniform magnetic field generated by the magnet ensures a constant contact pressure between the material and the polishing surface, while the groove structure captures rust particles. The electromagnet can automatically adjust the magnetic attraction strength according to the thickness of the material, and in conjunction with the telescopic drive component, it eliminates the clamping failure problem caused by material thickness differences in traditional devices. The flexible cloth reduces friction during movement while simultaneously providing surface protection and debris collection.

[0022] 2. The modular design of the conical block and polishing rod, through a matching sliding pair, forms a width-adaptive polishing system. The circumferential array of sliding structures ensures that the conical block can still transmit stable rotational torque during axial adjustment. The combined positioning mechanism of the spring telescopic rod and rotating wheel adapts to different widths of strip material through flexible clamping force, and the ball bearing structure on the end face of the support ring significantly reduces friction loss, making the rotation of the conical block more stable and ensuring uniform polishing roughness at the edges of strip materials of different widths.

[0023] 3. The flexible ring is made of rubber material, which can prevent the rotating wheel from scratching the surface of the strip. At the same time, this structure increases the coefficient of friction between the rotating wheel and the strip, ensuring the stability of positioning and effectively limiting the forward and backward displacement of the strip, thereby improving the polishing accuracy. The elasticity of the flexible ring can absorb the slight vibration in the polishing operation, reduce the processing deviation caused by vibration, and ensure the uniformity of polishing quality.

[0033] Embodiments of the present invention are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] In the existing technology, when using strip material 13 to process workpieces, the surface of strip material 13 may rust due to storage reasons. Currently, most of the methods are to grind and polish the workpiece after processing. After the surface of strip material 13 rusts, it will affect the processing accuracy of the workpiece. When grinding, because strip material 13 is stored in rolls, uneven grinding is very likely to occur during the grinding process.

[0035] like Figures 1 to 7 As shown, a workpiece rust removal device of the present invention includes a frame 1, a feeding roller 11 disposed on the left side of the frame 1 and a receiving roller 12 disposed on the right side of the frame 1, and further includes: at least two positioning mechanisms 2, which are respectively installed in the frame 1 and staggered from each other in the left-right direction. The positioning mechanisms 2 are arranged in groups of at least two, and multiple groups can be set. The two positioning mechanisms 2 are respectively disposed on the upper and lower sides of the strip 13. The projections of the multiple positioning mechanisms 2 on the plane where the strip 13 is located do not overlap. The positioning mechanism 2 includes a magnet 21 for adsorbing the strip 13 and two positioning parts 22 symmetrically mounted on the magnet 21 for clamping the two sides of the strip 13. It can be an electromagnet, which can adjust the magnetism of magnet 21 when cleaning debris, so as to facilitate the collection of debris on magnet 21. Two positioning parts 22 are installed in the groove 23 set on the side of magnet 21 near the material 13. The positioning parts 22 slide along the groove 23 in the direction of approaching / moving away from the material 13 to limit the movement of material 13 in the front-back direction. The two magnets 21 are slidably installed in the frame 1, and the magnets 21 are respectively located on the upper and lower sides of the material 13. The side of magnet 21 near the material 13 is provided with groove 23. The two positioning parts 22 are symmetrically arranged at both ends in the groove 23, and the positioning parts 22 can slide in the front-back direction.

[0036] During the polishing process of strip 13, the configured magnet 21 ensures that strip 13 is firmly attached to the processing base surface through magnetic field attraction. The groove 23 on the surface of magnet 21 is equipped with a combined polishing mechanism 3, which includes a rotating polishing rod 31 and a conical block 32. The two work together to achieve uniform processing of the strip surface. During the polishing process, the magnetic field on both sides of the groove 23 forms a dynamic confinement field, which controls the mechanical resonance generated during processing in real time and ensures the stability of the surface treatment. The positioning component 22, together with the spring telescopic rod 24, regulates the running path of the strip through a bidirectional stress balance mechanism, maintains the contact pressure of the polishing rod 31 along the width direction, and eliminates the problem of excessive edge grinding caused by the deviation of strip 13.

[0037] like Figures 2 to 6 As shown, a polishing mechanism 3 is installed on the side of the magnet 21 near the strip 13. Two conical blocks 32 are slidably installed at both ends of the polishing rod 31. The polishing rod 31 is rotatably set in the groove 23, and a part of the polishing rod 31 protrudes from the groove 23. The polishing rod 31 is rotatably set in the groove 23, and the polishing rod 31 is closer to the strip 13 than the magnet 21. During polishing, the polishing rod 31 can fully contact the strip 13 to ensure the polishing effect. The two conical blocks 32 are symmetrically arranged at both ends of the polishing rod 31 and can slide back and forth along the polishing rod 31 to adapt to different types of strips 13. The conical blocks 32 rotate synchronously with the polishing rod 31 and polish the side of the strip 13.

[0038] By setting the initial spacing of the magnets 21, it is ensured that the strip 13 remains straight during transmission, and the deformation of the relatively thin strip under strong magnetic adsorption is avoided. The gradient magnetic induction configuration of the magnets 21 ensures the stability of the strip 13 while reducing the magnetic adsorption energy consumption per unit area. The automatic fitting of the conical block 32 enables the edge polishing angle to dynamically adapt to the strip 13.

[0039] During the polishing operation, when the edge of the strip 13 deviates, the rotating wheel 26, under the elastic support of the spring telescopic rod 24, adaptively adjusts to keep the strip 13 in the middle position, effectively limiting the deviation of the strip 13 and allowing both ends of the strip 13 to be polished stably.

[0040] like Figures 2 to 5 As shown, a groove 14 is provided on the end face of the magnet 21 that is in close contact with the strip 13. The groove 14 is located on both sides of the groove 23. Multiple grooves 14 can be provided. When the strip 13 moves relative to the magnet 21, the groove 14 collects the remaining impurities on the strip 13. During the polishing process, the strip 13 will continuously move from the feed roller 11 to the take-up roller 12. When it moves, the groove 14 collects the impurities on the part of the strip 13 that passes through it.

[0041] The telescopic drive assembly 28 uses an electric telescopic rod. Its cylinder end is fixed to the magnet 21 via a flange, and its telescopic end is connected to the support ring 25. The support ring 25 is a ring-shaped frame structure made of hard alloy, with an inner diameter larger than the diameter of the tail end of the conical block 32. The spring telescopic rod 24 has a built-in spring, and its sleeve end is fixed to the support ring 25 with bolts. The telescopic end is equipped with a polyurethane rotating wheel 26. When the width of the strip 13 changes, the telescopic drive assembly 28 pushes the support ring 25 to move back and forth along the groove 23, causing the rotating wheel 26 to move synchronously. The compression of the spring telescopic rod 24 changes accordingly, forming an adaptive clamping force that prevents the strip 13 from deviating and also prevents overpressure deformation.

[0042] like Figure 4 and Figure 7 As shown, the polishing rod 31 has dovetail-shaped grooves 33 at both ends, and the inner hole of the conical block 32 has corresponding metal protrusions 34. In use, the conical block 32 slides along the axis of the polishing rod 31. When it contacts the edge of the strip 13, the conical block 32 polishes the edge of the strip 13. The polishing rod 31 is driven to rotate by the rotary drive assembly 35 through a reducer, and the polishing rod 31 synchronously drives the conical block 32 to move circumferentially. During polishing, the axial position of the conical block 32 is adjusted by the advance amount of the support ring 25, ensuring that the chamfer on the side of the strip 13 is uniform. When the width of the strip 13 changes, the operator can adjust the advance amount of the support rings 25 on both sides to make the conical block 32 synchronously expand outward or contract inward on the polishing rod 31. This linkage mechanism ensures symmetrical polishing pressure on both sides.

[0043] The flexible cloth on the surface of magnet 21 is woven from aramid fibers and bonded to the magnetic pole surface with a high-temperature resistant adhesive. During the movement of the conveyor belt 13, the fuzzy layer on the surface of the flexible cloth effectively captures metal debris. When the electromagnet 21 is de-energized, the debris accumulated in the fuzzy layer automatically detaches, and the flexible cloth is cleaned using a vacuum cleaner for easy reuse. This design ensures that the device maintains a high impurity capture efficiency even after continuous operation. The telescopic drive assembly 28 is driven by a servo-electric telescopic cylinder, which automatically adjusts the distance between the two conical blocks 32 according to the width parameter of the conveyor belt 13, ensuring that the conical blocks 32 on both sides are polished to a uniform degree as the conveyor belt 13 passes through.

[0044] like Figures 3 to 6 As shown, both ends of the polishing rod 31 are provided with grooves 33 arranged in a circumferential array, and the inner hole of the conical block 32 is provided with ridges 34 arranged in a circumferential array. The grooves 33 and ridges 34 slide in fit, and the grooves 33 and ridges 34 are correspondingly arranged. The conical blocks 32 are symmetrically arranged on the polishing rod 31, and the conical blocks 32 slide along the polishing rod 31 in the front-back direction at both ends.

[0045] The electromagnetic properties of magnet 21 and the telescopic drive assembly 28 form a closed-loop control system, achieving automatic matching between the width of the strip 13 and the positioning device, eliminating the stress concentration problem caused by traditional mechanical clamping. The combination of spring telescopic rod 24 and rotating wheel 26 ensures stable positioning of materials of different widths. The modular connection design of the conical block 32 and polishing rod 31, along with the ball bearings on the support ring 25, ensures stable polishing of the edges of the strip 13 by the conical block 32, while the rotating wheel 26 effectively counteracts the offset of the strip 13. The composite cleaning interface formed by the indentation 14 and the flexible cloth significantly improves debris capture efficiency while ensuring the surface quality of the strip 13. This achieves uniform polishing quality under stable feed conditions while reducing energy consumption.

[0046] like Figures 2 to 7 As shown, the positioning component 22 is slidably disposed in the groove 23. The positioning component 22 includes a spring telescopic rod 24, a support ring 25, a rotating wheel 26, and a telescopic drive assembly 28. The telescopic drive assembly 28 is installed in the mounting groove on the inner wall of the groove 23. The fixed end of the telescopic drive assembly 28 is fixedly connected to the magnet 21, and the other end of the telescopic drive assembly 28 is fixedly connected to the support ring 25. The telescopic drive assembly 28 can drive the support ring 25 to move in the front-back direction in the groove 23. The spring telescopic rod 24 is disposed on the end face of the support ring 25 near the material 13. One end of the spring telescopic rod 24 is fixedly connected to the support ring 25, and the other end of the spring telescopic rod 24 is fixedly attached to the rotating wheel 26. In the initial state, the rotating wheel 26 is closer to the side of the material 13 than the conical block 32, and the support ring 25 abuts against the tail end of the conical block 32. The spring telescopic rod 24 initially has elastic potential energy.

[0047] The cooperation between groove 23 and magnet 21 ensures the sliding accuracy of positioning component 22 while forming a closed debris collection cavity. When rust chips falling off the surface of material 13 move along the direction of movement, the shoulder structures on both sides of groove 23 effectively limit lateral diffusion, forming a multi-stage collection system in conjunction with the chip storage unit of recess 14. When polishing is complete, the periodic demagnetization of electromagnet 21 separates the debris accumulated in groove 23 and recess 14 from magnet 21. This spatial separation design significantly reduces the risk of secondary contamination during polishing while maintaining the cleanliness of the magnetic surface.

[0048] One end face of the support ring 25 abuts against the bottom surface of the conical block 32, and the ball bearings on its end face reduce the friction between the support ring 25 and the conical block 32 during polishing.

[0049] The balls are made of silicon nitride ceramic and are evenly distributed along the circumference to form a rolling pair. This ball assembly forms a dynamic support surface on the contact surface between the support ring 25 and the conical block 32. When the conical block 32 is axially adjusted, the balls stably drive the conical block 32 to slide along the axial direction. When the conical block 32 rotates relative to the support ring 25, the rolling friction coefficient of the balls is only 10% of that of traditional sliding friction. The end face of the support ring 25 is machined with an annular oil groove, allowing for lubrication maintenance via a micro-oil nozzle. High-temperature resistant grease can be injected periodically and quantitatively to ensure the long-term smooth operation of the ball assembly. A hard alloy wear-resistant layer is provided at a corresponding position on the bottom surface of the conical block 32, and its surface is treated with a diamond-like carbon coating to form an optimal friction pair match with the silicon nitride ceramic balls.

[0050] like Figures 2 to 6 As shown, a flexible cloth is provided on the surface where the magnet 21 and the strip 13 are in close contact. The flexible cloth is provided on the part where the magnet 21 and the strip 13 are in direct contact. During polishing, the magnet 21 and the strip 13 move relative to each other. The flexible cloth prevents the magnet 21 from scratching the surface of the strip 13, and the flexible cloth will wipe and clean the surface of the strip 13.

[0051] Simultaneously, a velvety structure forms on the surface of the flexible fabric. This velvety layer generates an electrostatic adsorption effect during polishing, enhancing the ability to capture abrasive particles from the surface of the strip 13. As the strip 13 continuously passes through the magnetic field gap formed by the upper and lower magnets 21, the velvety layer on the surface of the flexible fabric comes into contact with the surface of the strip 13, cleaning and collecting the abrasive debris from the surface of the strip 13.

[0052] The flexible cloth can be replaced. After a period of use, as the nap layer on the surface of the flexible cloth is worn away, the effect of the flexible cloth in reducing scratches on the material belt and wiping the material belt will decrease. At this time, the flexible cloth can be replaced as needed to keep the flexible cloth in a good cleaning condition.

[0053] like Figures 3 to 7 As shown, a telescopic drive assembly 27 is installed on the frame 1. One end of the telescopic drive assembly 27 is fixed to the frame 1, and the other end is fixed to the magnet 21. The magnet 21 is controlled to slide in the vertical direction on the frame 1. The telescopic drive assembly 27 is located on the frame 1. The telescopic drive assembly 27 can be an electric telescopic cylinder or a hydraulic telescopic cylinder, etc. The fixed end of the telescopic drive assembly 27 is set on the frame 1, and the movable end is fixed to the magnet 21. The telescopic drive assembly 27 controls the magnet 21 to move closer to / away from the conveyor belt 13 in the vertical direction.

[0054] The telescopic drive assembly 28 can adjust the distance between the two conical blocks 32 before rust removal begins, allowing the two conical blocks 32 to quickly adapt to the strip 13 to be ground. The telescopic drive assembly 27 can quickly adjust the position of multiple magnets 21 to limit the position of the strip 13, keeping it stable during grinding and ensuring the grinding effect. The telescopic drive assembly 27 can also adjust the distance between multiple magnets 21 up and down to accommodate strips 13 of different thicknesses and limit their movement, ensuring the stability of the grinding process. This allows the equipment to quickly adapt to grinding different strips 13. The polishing mechanism 3 adopts a modular combination design of a rotating polishing rod 31 and an adjustable conical block 32, combined with the elastic compensation mechanism of the spring telescopic rod 24, to achieve synchronous and uniform treatment of the surface and sides of the strip 13. The adaptive function of its rotating wheel 26 can eliminate the problem of over-polishing the edges in traditional processes.

[0055] like Figures 2 to 5 As shown, the polishing mechanism 3 includes a rotary drive assembly 35 mounted on the magnet 21. The rotary drive assembly 35 is fixedly mounted on the magnet 21. The rotary drive assembly 35 can be a hydraulic motor or an electric motor, etc. The output end of the rotary drive assembly 35 is connected to the polishing rod 31. During polishing, the rotary drive assembly 35 drives the polishing rod 31 and the conical block 32 to rotate.

[0056] The output end of the rotary drive assembly 35 is connected to the polishing rod 31 via a gearbox. During polishing, the rotary drive assembly 35 drives the polishing rod 31 and the conical block 32 to rotate. The polishing rod 31 can grind and polish the flat surface of the material strip 13, while the conical block 32, which rotates synchronously with the material strip 13, can grind the two sides of the material strip 13. The rotary drive assembly 35 uses a hydraulic motor or an electric motor. The hydraulic motor is connected to the hydraulic power unit inside the frame 1 via hydraulic lines, and the output speed and torque parameters can be adjusted in real time. The hydraulic transmission system can have an automatic overload protection function, and can generate a constant contact pressure when the conical block 32 contacts the edge of the material strip. The surface of the hydraulic motor housing is provided with annular heat dissipation fins, and its bottom is tightly attached to the mounting surface of the magnet 21 through a thermally conductive silicone pad, forming an efficient heat conduction path. This drive method is particularly suitable for working environments with high dust concentrations. The sealed structure of the hydraulic motor can effectively prevent metal debris generated during polishing from entering the rotating parts. Combined with the speed regulation characteristics of the gearbox, the polishing rod 31 maintains stable power transmission during polishing.

[0057] The implementation principle of the workpiece rust removal device of the present invention is as follows: the strip material 13 is fed from the feeding roller 11, positioned by the positioning mechanism 2, and then polished by the polishing mechanism 3. Finally, the polished strip material 13 is wound onto the receiving roller 12. When the strip material 13 passes the magnet 21, the magnet 21 attracts the strip material 13, restricting the strip material 13 from vibrating in the vertical direction. Two telescopic drive components 28 set in the groove 23 opened on the strip material 13 respectively drive the support ring 25 to move in the front-back direction in the groove 23 and approach the strip material 13. The spring telescopic rod 24 set on the support ring 25 drives the rotating wheel 26 fixed at its front end to abut against the front and rear side walls of the strip material 13, so that the strip material 13 moves in the front-back direction. Material 13 is located in the middle of magnet 21 in the front-to-back direction. The telescopic drive assembly 28 further drives the support ring 25 to move, causing the spring telescopic rod 24 to retract. When the conical block 32 that the support ring 25 abuts against the side of the material 13, the telescopic drive assembly 28 stops. The positioning member 22 on the other side of the material 13 moves in the same state and works on the same principle. After the positioning member 22 is positioned, the polishing mechanism 3 starts polishing. The rotary drive assembly 35 installed on magnet 21 drives the polishing rod 31 and the conical block 32 to rotate synchronously to polish the material 13. At the same time, the receiving roller 12 and the feeding roller 11 are adjusted to move in coordination, so that the material 13 is continuously fed to the polishing mechanism 3 for polishing.
