Description

Technical Field

[0001] The invention relates to the technical field of metal wire surface polishing, and in particular to a metal wire surface treatment device and process. Background Art

[0002] In the surface treatment of metal wires, in order to obtain a smooth surface, the surface needs to be polished. In the prior art, polishing is often performed by rotating a polishing piece around the circumference of the wire to cause friction between the polishing piece and the surface of the wire. This method causes the polishing piece to rotate at high speed, contact and rub against the surface of the wire to remove surface defects and oxide layers, thereby improving the surface quality of the wire.

[0003] When the grinding piece rotates at high speed around the circumference of the wire, a large centrifugal force is generated. This centrifugal force increases with the increase of rotation speed, causing great pressure on various parts of the equipment. Centrifugal force may cause the installation structure of the grinding piece to loosen, affecting the stability and accuracy of grinding. Due to the existence of centrifugal force, the transmission system of the equipment is under a large load. The motor and transmission gears that drive the grinding piece to rotate need to overcome the additional resistance caused by centrifugal force, which will increase the power consumption of the motor and accelerate the wear of the transmission gears. Centrifugal force may also cause vibration of the equipment, further exacerbating the damage to the equipment. Long-term vibration will loosen the connection parts of the equipment and even cause the breakage of key components. In order to cope with the impact of centrifugal force, the equipment usually needs to adopt a more sturdy structure and materials, which increases the manufacturing cost and maintenance difficulty of the equipment.

[0004] In summary, the polishing method of the prior art using a grinding piece rotating around the circumference of the wire has disadvantages such as large centrifugal force and easy damage to the equipment, which not only affects the surface treatment effect of the metal wire, but also increases the maintenance cost and production risk of the equipment. Therefore, a new metal wire surface treatment equipment and process are needed to overcome these problems. Summary of the invention

[0005] The present invention provides a metal wire surface treatment device and process, which solves the problem in the related art that a grinding element is used to rotate around the wire, which will generate a large centrifugal force.

[0010] Optionally, it further includes an adjusting wheel and a universal shaft, wherein the adjusting wheel is rotatably arranged on the supporting ring, and two ends of the adjusting wheel are universally hinged with the two screw rods by means of the two universal shafts.

[0011] Optionally, it further includes a gear ring and a gear, wherein the gear ring is rotatably arranged on the frame, the gear is coaxially arranged at the end of each supporting wheel, and the gear ring is meshed with the gear.

[0012] Optionally, a dustproof box is further included, which is arranged on the frame, the support ring and the polishing assembly are both located in the dustproof box, and the dustproof box has a dust removal port, which is used to connect to the dust removal unit.

[0013] Optionally, the support wheel is a hollow structure, a surface of the support wheel has a negative pressure hole, the negative pressure hole is connected to the support wheel, and the support wheel is used to connect to a negative pressure unit.

[0014] Optionally, it also includes a negative pressure hose and a rotary joint, one end of the negative pressure hose is connected to the support wheel by means of the rotary joint, and the other end passes through the dustproof box and is used to communicate with the negative pressure unit.

[0015] Optionally, a metal wire surface treatment process uses a metal wire surface treatment device to polish the surface of the metal wire.

[0016] The working principle and beneficial effects of the present invention are: The metal wire surface treatment equipment is mainly composed of a frame, a support ring and a polishing assembly. The frame plays the role of overall support, and the support ring is fixedly installed on the frame to provide a stable support foundation for the polishing assembly. The polishing assembly includes a polishing belt and at least two support wheels. The support wheel is rotatable relative to the support ring, and its installation method ensures that it remains stable and flexible during rotation. The polishing belt is sleeved on the support wheel, and the rotation of the support wheel drives the polishing belt to move. When the metal wire passes through the circumferential surface area jointly covered by multiple polishing belts in multiple polishing assemblies, multiple polishing belts contact the wire surface, so that the circumferential surface of the wire can be polished everywhere. Multiple polishing assemblies can also be staggered front and back along the axial direction of the wire, so as to obtain a more complete covering angle and a more sufficient covering effect, thereby improving the polishing effect.

[0017] During operation, the metal wire passes through the coating area formed by multiple polishing components. The support wheel rotates, driving the polishing belt to rub and polish the surface of the wire. Since the polishing belt moves linearly through the rotation of the support wheel instead of rotating around the circumference of the wire, it does not generate a large centrifugal force, thereby achieving efficient and stable polishing.

[0018] First, by adopting a combination of polishing belts and support wheels, the equipment avoids the problem of large centrifugal force generated by the grinding element rotating around the wire, reduces the pressure on each component of the equipment, and reduces the risk of equipment damage. Secondly, since there is no influence of centrifugal force, the transmission system of the equipment does not need to overcome additional resistance, the power consumption of the motor is reduced, and the wear of the transmission gear is greatly reduced, which extends the service life of the equipment and reduces maintenance costs. Furthermore, without the vibration caused by centrifugal force, the connection parts of the equipment are more stable, and key components are not easy to break, which improves the reliability and stability of the equipment. Finally, multiple polishing belts in multiple polishing assemblies jointly cover the circumferential surface of the wire, which can achieve all-round polishing processing and improve the surface quality and processing efficiency of the metal wire.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] Reference Figure 1~Figure 5, which is the first embodiment of the present invention, proposes a metal wire surface treatment device, including a frame 1, a support ring 2 and a polishing assembly 3, the support ring 2 is arranged on the frame 1, the polishing assembly 3 includes a polishing belt 4 and at least two support wheels 5, the support wheel 5 is rotatably arranged relative to the support ring 2, the polishing belt 4 is sleeved on the support wheel 5, the polishing belt 4 contacts the wire surface, the polishing assembly 3 is multiple, and the multiple polishing belts 4 in the multiple polishing assemblies 3 are used to jointly cover the circumferential surface of the wire.

[0027] In this embodiment, the metal wire surface treatment equipment is mainly composed of a frame 1, a support ring 2 and a polishing assembly 3. The frame 1 plays the role of overall support, and the support ring 2 is fixedly mounted on the frame 1 to provide a stable support base for the polishing assembly 3. The polishing assembly 3 includes a polishing belt 4 and at least two support wheels 5. The support wheel 5 is rotatably arranged relative to the support ring 2, and its installation method ensures that it remains stable and flexible during the rotation process. The polishing belt 4 is sleeved on the support wheel 5, and the polishing belt 4 is driven to move by the rotation of the support wheel 5. When the metal wire passes through the circumferential surface area jointly covered by multiple polishing belts 4 in multiple polishing assemblies 3, multiple polishing belts 4 contact the surface of the wire, so that the circumferential surface of the wire can be polished everywhere. Multiple polishing assemblies 3 can also be staggered front and back along the axial direction of the wire, so as to obtain a more complete covering angle and a more sufficient covering effect, thereby improving the polishing effect.

[0028] During operation, the metal wire passes through the covering area formed by the multiple polishing components 3. The support wheel 5 rotates, driving the polishing belt 4 to perform friction polishing on the surface of the wire. Since the polishing belt 4 performs linear motion through the rotation of the support wheel 5 rather than rotating around the circumference of the wire, it does not generate a large centrifugal force, thereby achieving efficient and stable polishing.

[0029] First, the device avoids the problem of large centrifugal force caused by the grinding element rotating around the wire by adopting a combination of a polishing belt 4 and a supporting wheel 5, reduces the pressure on each component of the device, and reduces the risk of equipment damage. Secondly, since there is no influence of centrifugal force, the transmission system of the equipment does not need to overcome additional resistance, the power consumption of the motor is reduced, and the wear of the transmission gear 13 is also greatly slowed down, which extends the service life of the equipment and reduces maintenance costs. Furthermore, there is no vibration caused by centrifugal force, the connection parts of the equipment are more stable, and key components are not easy to break, which improves the reliability and stability of the equipment. Finally, the multiple polishing belts 4 in the multiple polishing assemblies 3 jointly cover the circumferential surface of the wire, which can achieve all-round polishing processing and improve the surface quality and processing efficiency of the metal wire.

[0030] Furthermore, a plurality of the polishing belts 4 are sleeved on the supporting wheel 5 , and the plurality of polishing belts 4 in the plurality of groups of the polishing assemblies 3 are arranged in an interlaced manner.

[0031] In this embodiment, in the metal wire surface treatment equipment, multiple polishing belts 4 are mounted on each supporting wheel 5. When there are multiple sets of polishing components 3, taking two sets of polishing components 3 distributed upper and lower as an example, the multiple polishing belts 4 in the upper polishing component 3 and the multiple polishing belts 4 in the lower polishing component 3 are staggered with each other.

[0032] During operation, the metal wire passes between the upper and lower groups of polishing components 3, and the upper and lower groups of polishing belts 4 jointly apply force to the wire, so that the wire is evenly stressed. As the support wheel 5 rotates, the multiple polishing belts 4 of the upper and lower groups polish the wire at the same time. Since the multiple polishing belts 4 are staggered, the wire is simultaneously affected by multiple points of force in the upper and lower directions. Each polishing belt 4 serves as an independent point of force, so that the force on the surface of the wire is more uniform. This staggered distribution method avoids deformation of the wire due to excessive force in a single direction.

[0033] Furthermore, it also includes a support rod 6, which is rotatably disposed on the support ring 2, and the support wheel 5 is rotatably disposed on the support rod 6. After the support rod 6 is rotated, it is used to adjust the contact angle between the polishing belt 4 and the wire.

[0034] In this embodiment, when it is necessary to adjust the contact angle between the polishing belt 4 and the wire, it can be achieved by rotating the support rod 6. The support rod 6 rotates on the support ring 2, driving the support wheel 5 and the polishing belt 4 sleeved on the support wheel 5 to move. By changing the angle of the support rod 6, the contact between the polishing belt 4 and the wire can be adjusted, thereby changing the angle and contact area of ​​the polishing belt 4 covering the wire. When it is necessary to increase the angle, the two support wheels 5 can be brought closer to each other, so that the support wheels 5 drive the polishing belt 4 to surround the wire more closely, thereby increasing the contact angle and contact area. Conversely, when it is necessary to reduce the angle, the two support wheels 5 can be moved away from each other.

[0035] First, the contact angle between the polishing belt 4 and the wire can be flexibly adjusted by swinging the support rod 6 to meet the requirements of different wire diameters and surface treatment. For wires with larger diameters, the contact angle can be increased to ensure a sufficient polishing effect; for wires with smaller diameters, the contact angle can be appropriately reduced to avoid over-polishing. Secondly, the area of ​​the wire covered by the polishing belt 4 can be accurately controlled, which improves the adaptability and processing accuracy of the equipment and enables the equipment to process metal wires of various specifications.

[0036] Furthermore, it also includes a slider 7, a tensioning wheel 8 and a screw 9. The slider 7 is radially slidably arranged on the support ring 2, and the tensioning wheel 8 is rotatably arranged on the slider 7. The tensioning wheel 8 is used to keep the polishing belt 4 tensioned. The screw 9 is rotatably arranged on the support ring 2. The screw 9 is threadedly connected to the slider 7. The number of the screws 9 is the same as the number of the sliders 7 and corresponds one to one.

[0037] In this embodiment, the slider 7 can slide on the support ring 2 along the radial direction of the support ring 2, and the tensioning wheel 8 is rotatably mounted on the slider 7, and its main function is to maintain the tension state of the polishing belt 4. The screw 9 is rotatably arranged on the support ring 2, and the screw 9 is threadedly connected with the slider 7, and the number of the screw 9 is the same as the number of the slider 7 and corresponds one to one.

[0038] When the positions of the support rod 6 and the support wheel 5 change and cause the polishing belt 4 to become loose, or when the tension of the polishing belt 4 needs to be adjusted, the operator can adjust the position of the tension wheel 8 by rotating the screw rod 9. When the screw rod 9 rotates, due to the threaded connection with the slider 7, the slider 7 will slide along the radial direction of the support ring 2. As the slider 7 moves, the tension wheel 8 will also move accordingly, thereby changing the tension of the polishing belt 4.

[0039] Furthermore, it also includes an adjusting wheel 10 and a universal shaft 11. The adjusting wheel 10 is rotatably arranged on the supporting ring 2. Two ends of the adjusting wheel 10 are universally hinged with the two screw rods 9 by means of the two universal shafts 11.

[0040] In this embodiment, in order to ensure that the wire is evenly stressed in all directions, the tension of multiple sets of polishing belts 4 needs to be as close as possible. Therefore, when adjusting the screw rods 9, it is necessary to ensure that multiple screw rods 9 rotate synchronously, so as to ensure that the tension adjustment amount of multiple sets of polishing belts 4 is consistent. However, since the center position of the support ring 2 needs to convey the wire, it is impossible to arrange a synchronous adjustment structure at the center position.

[0041] To this end, one end of the adjusting wheel 10 is universally hinged to one screw rod 9 by means of a universal shaft 11, and the other end of the adjusting wheel 10 is universally hinged to another screw rod 9 by means of another universal shaft 11. In this way, the two screw rods 9 can be synchronously rotated by simply rotating the adjusting wheel 10. Usually, in order to ensure the rationality of the structure, the two screw rods 9 are generally arranged relatively.

[0042] Both ends of the universal shaft 11 have a universal joint, which can realize universal articulation with the screw 9. When the tension of multiple groups of polishing belts 4 needs to be adjusted, the operator rotates the adjusting wheel 10, and the rotation of the adjusting wheel 10 is transmitted to the screw 9 articulated therewith through the universal shaft 11. Due to the action of the universal shaft 11, even if the position and angle of the screw 9 are different, the screw 9 can also be rotated synchronously.

[0043] First, through the design of the adjusting wheel 10 and the universal shaft 11, the synchronous rotation of multiple screws 9 is achieved, thereby ensuring that the tension adjustment of multiple groups of polishing belts 4 is consistent, ensuring that the wire is evenly stressed in all directions, and improving the quality of surface treatment. Secondly, the universal articulation function of the universal shaft 11 solves the problem of being unable to arrange a synchronous structure due to the need to transport wires at the center position, making the structure of the equipment more reasonable and compact. The operation is simple, and the synchronous adjustment of multiple screws 9 can be achieved by simply turning the adjusting wheel 10, which reduces the difficulty of operation and improves work efficiency.

[0044] Furthermore, it also includes a ring gear 12 and a gear 13 . The ring gear 12 is rotatably arranged on the frame 1 . The end of each supporting wheel 5 is coaxially provided with the gear 13 . The ring gear 12 is meshed with the gear 13 .

[0045] In this embodiment, the ring gear 12 is rotatably mounted on the frame 1, and a motor is mounted at the bottom of the frame 1, and the motor is drivingly connected to the ring gear 12. A gear 13 is coaxially arranged at the end of each support wheel 5. When the motor is started, the ring gear 12 is driven to rotate. Since the ring gear 12 is meshed with the gears 13 at the ends of each support wheel 5, the rotation of the ring gear 12 will drive multiple gears 13 to rotate simultaneously. Because the gear 13 is coaxially arranged with the support wheel 5, when the gear 13 rotates, the support wheel 5 will also rotate synchronously.

[0046] During operation, the power of the motor drives the gear ring 12, so that the gear ring 12 drives the multiple gears 13 to rotate, and then controls the multiple support wheels 5 to rotate synchronously, so that the multiple polishing belts 4 sleeved on the support wheels 5 can realize synchronous operation. When the metal wire passes through the polishing area, the multiple polishing belts 4 can polish the surface of the wire at the same speed and pressure, ensuring the uniformity and consistency of the surface treatment of the wire, so that the polishing force of each part of the wire during the polishing process is consistent, and the quality and accuracy of the surface treatment are improved.

[0047] Furthermore, it also includes a dustproof box 14, which is arranged on the frame 1, and the support ring 2 and the polishing assembly 3 are both located in the dustproof box 14. The dustproof box 14 has a dust removal port 15, and the dust removal port 15 is used to connect with the dust removal unit.

[0048] In this embodiment, the dustproof box 14 is installed on the frame 1 to accommodate the support ring 2 and the polishing assembly 3 inside, and a dust removal port 15 is provided on the top of the dustproof box 14 .

[0049] During the operation of the equipment, the polishing of the metal wire is carried out in the dustproof box 14. When the polishing belt 4 rubs and polishes the surface of the wire, a certain amount of dust and particulate matter will be generated. Since the support ring 2 and the polishing assembly 3 are both located in the dustproof box 14, the dust is confined in a relatively closed space, thereby avoiding dust. At the same time, by connecting the dust removal port 15 to a dust removal unit, such as a dust collector or a dust removal duct, the dust in the dustproof box 14 can be effectively removed. The negative pressure generated by the dust removal unit acts on the inside of the dustproof box 14 through the dust removal port 15, and the dust and particulate matter are sucked into the dust removal system for processing, thereby ensuring a clean working environment.

[0050] Furthermore, the support wheel 5 is a hollow structure, and a negative pressure hole 16 is provided on the surface of the support wheel 5 . The negative pressure hole 16 is communicated with the support wheel 5 , and the support wheel 5 is used to connect to a negative pressure unit 17 .

[0051] In this embodiment, when the polishing belt 4 rotates with the support wheel 5, the dust generated during the polishing process may adhere to the inner ring surface of the polishing belt 4. At this time, negative pressure is generated through the cavity inside the support wheel 5 and the negative pressure hole 16 on the surface. The negative pressure causes the dust attached to the inner ring of the polishing belt 4 to be sucked into the negative pressure hole 16 and enter the inside of the support wheel 5, which can effectively remove the dust attached to the inner ring of the polishing belt 4 and keep the polishing belt 4 clean. Since the dust is removed in time, the polishing belt 4 can better contact with the support wheel 5. Without the influence of dust, the operation of the polishing belt 4 on the support wheel 5 is more stable, and the contact with the surface of the wire is closer and more uniform, thereby improving the polishing effect.

[0052] First, the hollow structure of the support wheel 5 and the design of the negative pressure hole 16 can timely remove dust attached to the inner circle of the polishing belt 4, maintain the cleanliness of the polishing belt 4, help to improve the service life of the polishing belt 4, and reduce the wear and damage caused by dust accumulation. Secondly, the polishing belt 4 is better in contact with the support wheel 5, which ensures the stability and consistency of the polishing process. The stable contact can ensure that the polishing belt 4 applies uniform pressure to the surface of the wire, thereby improving the quality and accuracy of the surface treatment.

[0053] Furthermore, it also includes a negative pressure hose 18 and a rotary joint 19 , one end of the negative pressure hose 18 is connected to the support wheel 5 via the rotary joint 19 , and the other end passes through the dustproof box 14 and is used to communicate with the negative pressure unit 17 .

[0054] In this embodiment, the support wheel 5 will continuously rotate while driving the polishing belt 4 to polish the metal wire. Since the negative pressure hose 18 is connected to the support wheel 5 through the rotary joint 19, even if the support wheel 5 is rotating, it will not affect the connection between the negative pressure hose 18 and the support wheel 5. The rotary joint 19 can ensure that the negative pressure hose 18 always maintains a smooth connection with the hollow structure inside the support wheel 5 while the support wheel 5 rotates, so that the negative pressure generated by the negative pressure unit 17 can continuously act on the negative pressure hole 16 on the surface of the support wheel 5. The negative pressure hose 18 passes through the dustproof box 14 and is connected to the negative pressure unit 17, so that the rotation of the support wheel 5 will not cause confusion or interfere with the operation of other components, thereby improving the overall performance and stability of the equipment.

[0055] Furthermore, a metal wire surface treatment process uses a metal wire surface treatment device to polish the surface of the metal wire.
