Description

Technical Field

[0001] This invention relates to the field of copper tube polishing technology, specifically to a polishing equipment and process for copper tube processing. Background Technology

[0002] In the field of copper tube processing, polishing is a key process. Its purpose is to remove defects such as burrs and oxide layers from the surface of copper tubes, and improve the smoothness and quality of the copper tube surface to meet the needs of different industrial applications.

[0003] In the existing copper tube processing and polishing process, due to the large size differences of copper tubes of different specifications and the complex and variable production environment and process requirements, the main air jet head of traditional polishing equipment is fixed in position, making it difficult to flexibly adjust it to be directly above different copper tubes for precise pre-treatment and cooling operations according to actual needs. This results in poor cooling pre-treatment effect when facing various working conditions, uneven temperature drop on the surface of the copper tube, and easy generation of stress changes and surface defects. These defects will seriously affect the subsequent polishing process, making it difficult for the polished copper tube surface to achieve the ideal effect of smoothness and flatness, thus reducing the quality and market competitiveness of copper tube products.

[0004] Therefore, this invention proposes a polishing device and process for copper tube processing to solve the above problems. Summary of the Invention

A pointer is fixedly connected to one end of each fixing post near the scale strip, and the pointer corresponds to the scale strip.

[0013] A polishing process for copper tube processing includes the following steps: Step 1: Place the polishing equipment in a stable, dry and well-ventilated work area, connect the power supply and check the firmness, looseness and damage of the connections between the various parts of the equipment, then select the copper tube to be polished and check its surface; Step 2: Place the copper tube in the clamping device of the equipment, adjust the clamping force according to the diameter of the copper tube, select the corresponding model and material polishing wheel according to the copper tube material and polishing requirements, and install it on the drive shaft of the equipment.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a polishing device and process for copper tube processing, which has the following beneficial effects: 1. The cooling position adjustment mechanism allows the main jet head to be moved directly above the copper tube body, blowing compressed air onto the surface of the copper tube body from directly above to pre-treat and cool the surface. This not only allows the position of the main jet head to be flexibly adjusted according to actual needs, but also ensures that the main jet head can be accurately moved directly above the copper tube body with simple operation, regardless of the copper tube specifications or different production environments and process requirements, thus enhancing the equipment's adaptability to various working conditions. Furthermore, the compressed air blown from directly above the copper tube body by the main jet head for pre-treatment and cooling ensures that the surface temperature of the copper tube drops evenly, reducing stress changes and surface defects caused by uneven temperature. This creates favorable conditions for the subsequent polishing process, helping to improve the polishing quality of the copper tube surface and making the copper tube surface smoother and flatter. The design incorporates locking pins and holes to fix the position of the extension plate, improving the stability of the main jet head during operation. The elastic telescopic column's rebound force causes the locking pins to engage with the holes, firmly securing the extension plate and main jet head in a fixed position. This ensures that when compressed air is continuously blown onto the surface of the copper tube for cooling, the main jet head will not shift due to airflow reaction force or slight equipment vibration, maintaining a stable airflow direction and range, and guaranteeing a uniform and effective cooling effect.

[0017] 2. Through the connecting frame and horizontal groove, the hollow plate can be pressed down synchronously inside the vertical groove on the side wall of the support plate during the adjustment of the polishing machine height. This causes the extension plate and air supply pipe to move downwards, adjusting the distance between the main jet head and the copper tube body. This allows the main jet head to quickly spray compressed air onto the outer surface of the copper tube body for cooling. The main jet head can always spray compressed air evenly onto the outer surface of the copper tube at the optimal distance, achieving rapid and effective cooling. This avoids quality problems such as oxidation and deformation of the copper tube surface due to excessive temperature. It also helps maintain the performance stability of the polishing tool and extends its service life, thereby greatly enhancing the stability and reliability of the entire polishing process. Moreover, the various components are interconnected and work together through the connecting frame, hollow plate, vertical groove, and horizontal groove, achieving an organic combination of polishing and cooling functions, improving the overall performance and reliability of the equipment.

[0018] 3. The cooling angle adjustment mechanism allows for adjustment of the auxiliary jet head's tilt angle. This enables the auxiliary jet head to blow compressed air from both sides onto the outer surface of the copper tube body, cooling the outer surface. Not only can the tilt angle of the auxiliary jet head be precisely adjusted, but the blowing direction can also be flexibly adjusted for copper tubes of different diameters. This ensures compressed air reaches the copper tube surface from both sides at the optimal angle, achieving precise cooling and meeting diverse production needs. Furthermore, the adjustable angle of the auxiliary jet head according to the copper tube diameter allows for cooling the copper tube surface from both sides, resulting in a more uniform temperature distribution. This effectively reduces internal stress and surface defects caused by uneven temperature, providing favorable conditions for subsequent processing and ultimately improving the overall quality of the copper tube product.

[0019] 4. The combination of the pointer and scale bar not only provides operators with an intuitive reference for angle adjustment, but also allows them to accurately know the rising distance of the ring by observing the position change of the pointer on the scale bar. This enables precise control of the tilt angle of the auxiliary jet head, meeting the stringent requirements of different processes for the cooling angle. Furthermore, operators do not need to rely on experience or repeated attempts to adjust the angle of the auxiliary jet head; they only need to pay attention to the scale indicated by the pointer to quickly and accurately adjust the auxiliary jet head to the required angle, greatly simplifying the operation process, saving operation time, and improving work efficiency.

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] This embodiment provides a polishing device for copper tube processing, such as... Figure 1 - Figure 9 As shown, the system includes a polishing table 1, a drive roller 2 rotatably connected to the upper surface of the polishing table 1, an auxiliary roller 3 horizontally slidably connected to the upper surface of the polishing table 1, a copper tube body 4 placed between the drive roller 2 and the auxiliary roller 3, an adjustment frame 5 horizontally slidably connected to the upper surface of the polishing table 1, a polishing machine 6 mounted on the adjustment frame 5, a cooling position adjustment mechanism, and a cooling angle adjustment mechanism. The cooling position adjustment mechanism includes a support plate 701, a hollow plate 702 on the side of the support plate 701 near the copper tube body 4, an extension plate 704 slidably connected through the side of the hollow plate 702 away from the support plate 701, a groove 716 on the lower surface of the extension plate 704, an air supply pipe 706 fixedly connected through the extension plate 704, a main jet nozzle 709 fixedly connected to the lower end of the air supply pipe 706, the main jet nozzle 709 being located directly above the copper tube body 4, and the cooling position adjustment mechanism being used to adjust the position of the main jet nozzle 709 according to the diameter of the copper tube body 4.

[0025] In this embodiment, as Figure 4 and Figure 5 As shown, both sides of the hollow plate 702 are provided with through slots 708, and connecting blocks 710 are slidably connected in the through slots 708. The connecting blocks 710 are fixedly connected to the side wall of the extension plate 704. The lower end face of the connecting blocks 710 is fixedly connected with elastic telescopic columns 711. A horizontal plate 712 is fixedly connected between the lower ends of the two elastic telescopic columns 711. A pull plate 713 is fixedly connected at the center of the lower end face of the horizontal plate 712. When the pull plate 713 is pulled horizontally to move the horizontal plate 712, the horizontal plate 712 can move the connecting blocks 710 to slide synchronously in the through slots 708 through the elastic telescopic columns 711. At the same time, the connecting blocks 710 pull the extension plate 704 to slide out from the hollow plate 702.

[0026] In this embodiment, as Figure 4 and Figure 5 As shown, a locking post 714 is fixedly connected to the upper end of the horizontal plate 712, and locking holes 715 are equidistantly opened on the lower end surface of the hollow plate 702. The locking holes 715 are interlocked with each other. The position of the horizontal plate 712 can be fixed by the interlocking of the locking post 714 and the locking hole 715.

[0027] In this embodiment, as Figure 1 and Figure 2As shown, a horizontal groove 707 is provided on the upper surface of the hollow plate 702. A connecting frame 703 is slidably connected in the horizontal groove 707. The end of the connecting frame 703 away from the horizontal groove 707 is fixedly connected to the polishing machine 6. A vertical groove 705 is provided on the side of the support plate 701 near the hollow plate 702. The hollow plate 702 is slidably connected to the side wall of the support plate 701 through the vertical groove 705. When the polishing machine 6 moves horizontally, it will drive the connecting frame 703 to slide horizontally in the horizontal groove 707. When the polishing machine 6 moves downward, the connecting frame 703 can push the hollow plate 702 to move up and down synchronously by pressing the horizontal groove 707.

[0028] In existing copper tube processing and polishing processes, due to the significant size differences between copper tubes of different specifications and the complex and variable production environment and process requirements, the main air jet head 709 of traditional polishing equipment is fixed in position. This makes it difficult to flexibly adjust it to be directly above different copper tubes for precise pre-treatment cooling. Consequently, under diverse working conditions, the cooling pre-treatment effect is poor, the copper tube surface temperature drops unevenly, and stress changes and surface defects are easily generated. These defects severely affect subsequent polishing processes, making it difficult to achieve a smooth and flat surface after polishing, thus reducing the quality and market competitiveness of the copper tube products. Compared to existing technologies, this new technology allows the main air jet head 709 to be moved directly above the copper tube body 4, allowing for precise pre-treatment cooling from the copper tube body 4. Compressed air is blown directly above the surface of the copper tube body 4 to pre-treat and cool the surface. This not only allows the position of the main jet head 709 to be flexibly adjusted according to actual needs, but also enables the main jet head 709 to be accurately moved directly above the copper tube through simple operation, regardless of the copper tube specifications or different production environments and process requirements, ensuring the cooling pre-treatment effect and enhancing the equipment's adaptability to various working conditions. Furthermore, the compressed air blown from directly above the copper tube by the main jet head 709 for pre-treatment and cooling ensures that the surface temperature of the copper tube drops uniformly, reducing stress changes and surface defects caused by uneven temperature. This creates favorable conditions for the subsequent polishing process, helping to improve the polishing quality of the copper tube surface and making the copper tube surface smoother and flatter.

[0029] In other aspects, this embodiment also provides a cooling angle adjustment mechanism for adjusting the contact angle between compressed air and the surface of the copper tube body 4 according to the diameter of the copper tube body 4, such as... Figure 1 , Figure 6 - Figure 9As shown, the cooling angle adjustment mechanism includes a split pipe 802, which is fixedly connected to the lower end face of the air supply pipe 706 and is connected to the air supply pipe 706. Corrugated pipes 803 are fixedly connected to both ends of the split pipe 802. Auxiliary jet heads 804 are fixedly connected to the side of the corrugated pipe 803 away from the split pipe 802. Rotating shafts 807 are symmetrically fixedly connected to both sides of the split pipe 802. A lever plate 806 is rotatably connected to the outer surface of the rotating shaft 807, and the two lever plates 806 on the same side are staggered. Connecting posts 805 are symmetrically fixedly connected to the side of the corrugated pipe 803 away from the split pipe 802. The lever plates 806 are fixedly connected to the connecting posts 805 on the side away from the rotating shaft 807.

[0030] In this embodiment, as Figure 6 - Figure 9 As shown, a ring 811 is vertically slidably connected to the outer surface of the gas pipe 706. Vertical plates 808 are symmetrically fixedly connected to the outer surface of the ring 811, each located between two lever plates 806. Each lever plate 806 has a limiting groove 810 on the side closest to the vertical plate 808, and a lever 809 is slidably connected within each limiting groove 810. The levers 809 are fixedly connected to the vertical plates 808. A fixing post 812 is fixedly connected to the side of the vertical plate 808 away from the ring 811. A connecting plate 813 is rotatably connected to the outer surface of each fixing post 812. A movable plate 814 is rotatably connected between the two connecting plates 813 on the sides away from the fixing post 812. The movable plate 814 is slidably connected to the groove 716. A threaded rod 819 is threadedly connected to the movable plate 814. The threaded rod 819 is rotatably connected to the extension plate 704. A knob 801 is fixedly connected to one end of the threaded rod 819 through the extension plate 704. When the knob 801 is rotated, the threaded rod 819 is rotated. Through the threaded connection between the threaded rod 819 and the movable plate 814, the movable plate 814 can be driven to move horizontally in the groove 716. At this time, the movable plate 814 can pull the fixed column 812 through the connecting plates 813 rotatably connected on both sides, causing the ring 811 to slide up and down on the outer surface of the gas pipe 706.

[0031] In this embodiment, as Figure 6 and Figure 7 As shown, the lower end of the extension plate 704 is symmetrically and fixedly connected to a side plate 815. Each side plate 815 has a connecting groove 816. The fixed posts 812 are slidably connected in the connecting groove 816. Each side plate 815 has a scale bar 818 symmetrically and equidistantly fixedly connected to its side wall. A pointer 817 is fixedly connected to one end of the fixed post 812 near the scale bar 818. The pointer 817 corresponds to the scale bar 818. During the descent of the fixed post 812, it can drive the pointer 817 to rise and fall synchronously, changing the scale bar 818 pointed to by the pointer 817. By observing the scale bar 818 pointed to by the pointer 817, the operator can accurately control the height of the fixed post 812.

[0032] Compared with existing technologies, the adjustable tilt angle of the auxiliary jet head 804 allows it to blow compressed air from both sides onto the outer surface of the copper tube body 4 according to its diameter, thereby cooling the outer surface of the copper tube body 4. This not only allows for precise adjustment of the tilt angle of the auxiliary jet head 804, but also enables flexible adjustment of the blowing direction for copper tube bodies 4 of different diameters. This ensures that compressed air is blown onto the copper tube surface from both sides at the optimal angle, achieving precise cooling and meeting diverse production needs. Furthermore, the adjustable angle of the auxiliary jet head 804 according to the copper tube diameter allows for cooling of the copper tube surface from both sides, resulting in a more uniform temperature distribution on the copper tube surface. This effectively reduces internal stress and surface defects caused by uneven temperature, providing better conditions for subsequent processing and thus improving the overall quality of the copper tube products.

[0033] At other levels, this embodiment also provides a polishing process for copper tube processing, such as... Figure 1 - Figure 9 As shown, it includes the following steps: Step 1: Place the polishing equipment in a stable, dry and well-ventilated work area, connect the power supply and check the firmness, looseness and damage of the connections between the various parts of the equipment, then select the copper tube to be polished and check its surface; Step 2: Place the copper tube in the clamping device of the equipment, adjust the clamping force according to the diameter of the copper tube, select the corresponding model and material polishing wheel according to the copper tube material and polishing requirements, and install it on the drive shaft of the equipment. Check the installation securely again. Step 3: Apply polishing compound evenly to the surface of the copper tube in a circular motion, following the direction of the copper tube's texture; Step 4: Turn on the polishing equipment to start the polishing wheel rotating and polish the surface of the copper tube; Step 5: After polishing, turn off the equipment, wipe the surface of the copper tube with a cotton cloth, and place the copper tube in a well-lit place.

[0034] In this embodiment, in step 3, the polishing paste is first squeezed onto a clean soft cloth, and the soft cloth is dipped in the polishing paste and evenly applied to the surface of the copper tube in a circular motion along the direction of the copper tube texture.

[0035] In this embodiment, during the polishing operation in step 4, when polishing the bent part of the copper tube, the moving speed of the polishing wheel is reduced, the contact pressure is decreased, and polishing is paused every once in a while to check the polishing effect of the bent part. The polishing parameters are adjusted in a timely manner according to the actual situation.

[0036] The overall working process and principles involved in the above embodiments are as follows: When the worker needs to polish the surface of the copper tube body 4, first, according to the diameter of the copper tube body 4, drive the auxiliary roller 3 to move horizontally on the polishing table 1. Then, place the copper tube body 4 between the drive roller 2 and the auxiliary roller 3 to limit the position of the copper tube body 4. After the position of the copper tube body 4 is limited, the worker can drive the adjusting frame 5 to move horizontally to the designated position on the upper surface of the polishing table 1, driving the polishing machine 6 to move above the copper tube body 4. During the horizontal movement of the polishing machine 6, the polishing machine 6 will drive the connecting frame 703 connected to the side wall to move together. The connecting frame 703 is moved step by step, allowing it to slide horizontally within the transverse groove 707 on the hollow plate 702. After the polishing machine 6 is positioned above the copper tube body 4, the operator can adjust the height of the polishing machine 6 using the adjusting frame 5, allowing the polishing machine 6 to descend and fit against the outer surface of the copper tube body 4. At this time, since the connecting frame 703 is connected to the hollow plate 702 via the transverse groove 707, and the hollow plate 702 is slidably connected to the side wall of the support plate 701 via the vertical groove 705, and an extension plate 704 is slidably connected through the side wall of the hollow plate 702, the main spray... The air head 709 is connected to the extension pipe via the air supply pipe 706. Therefore, during the process of the polishing machine 6 descending to fit against the outer surface of the copper tube body 4, the connecting frame 703 can press the hollow plate 702 into the vertical groove 705 opened on the side wall of the support plate 701 to descend synchronously, and drive the extension plate 704 and the air supply pipe 706 to move downward, adjusting the distance between the main air head 709 and the copper tube body 4, so that the main air head 709 can quickly spray compressed air onto the outer surface of the copper tube body 4 for cooling, so that the main air head 709 can always spray compressed air onto the outer surface of the copper tube body 4 for cooling. Compressed air is evenly sprayed onto the outer surface of the copper tube at the optimal distance, achieving rapid and effective cooling. This avoids quality problems such as oxidation and deformation of the copper tube surface caused by excessive temperature. It also helps to maintain the performance stability of the polishing tool and extend its service life, thereby greatly enhancing the stability and reliability of the entire polishing process. Moreover, the various components are interconnected and work together through structures such as the connecting frame 703, hollow plate 702, vertical groove 705, and horizontal groove 707, achieving an organic combination of polishing and cooling functions, and improving the overall performance and reliability of the equipment. After the height of the main jet head 709 is adjusted, the operator can pull down the pull plate 713, causing the horizontal plate 712 to descend synchronously. This stretches the elastic telescopic columns 711 symmetrically connected to the upper end face of the horizontal plate 712. As the horizontal plate 712 descends, it can also cause the locking post 714 connected to the center of its upper end face to descend synchronously, separating from the locking hole 715 on the lower end face of the hollow plate 702. After the locking post 714 and the locking hole 715 are completely separated, the operator... The horizontally movable pull plate 713, via the horizontal plate 712 and the elastic telescopic column 711, pulls the connecting block 710 to slide horizontally within the through slot 708 opened on the side wall of the hollow plate 702. Since the connecting block 710 is connected to the side wall of the extension plate 704, and the extension plate 704 is slidably connected to the hollow plate 702, and the main jet head 709 is connected to the extension plate 704 via the air supply pipe 706, the horizontal sliding of the connecting block 710 within the through slot 708 drives the extension plate 702 to slide horizontally. Plate 704 slides out synchronously from inside hollow plate 702, and at the same time, it drives the main jet head 709 to move horizontally through air pipe 706, so that the main jet head 709 moves to directly above the copper tube body 4. Compressed air is blown from directly above the copper tube body 4 to the surface of the copper tube body 4 to pre-treat and cool the surface of the copper tube body 4. This not only allows the position of the main jet head 709 to be flexibly adjusted according to actual needs, but also ensures that the main jet head 709 can be accurately moved to directly above the copper tube through simple operation, regardless of the copper tube specifications or different production environments and process requirements, thus enhancing the equipment's adaptability to various working conditions. Moreover, the main jet head 709 blowing compressed air from directly above the copper tube to the surface for pre-treatment and cooling can make the surface temperature of the copper tube drop evenly, reducing stress changes and surface defects caused by uneven temperature. This creates good conditions for the subsequent polishing process, helps to improve the polishing quality of the copper tube surface, and makes the copper tube surface smoother and flatter. After the position of the main jet head 709 is adjusted, the operator can release the pull plate 713. Through the rebound force of the elastic telescopic column 711 connected between the horizontal plate 712 and the connecting block 710, the horizontal plate 712 can be pulled to automatically approach the hollow plate 702, so that the locking column 714 connected to the horizontal plate 712 can be locked into the locking hole 715 again, thereby fixing the position of the extension plate 704 and improving the stability of the main jet head 709 during operation. The rebound force of the elastic telescopic column 711 makes the locking column 714 lock into the locking hole 715, which can firmly fix the extension plate 704 and the main jet head 709 in a certain position, ensuring that when compressed air is continuously blown onto the surface of the copper tube body 4 for cooling, the main jet head 709 will not be displaced due to the airflow reaction force or slight vibration of the equipment, maintaining a stable airflow spray direction and range, and ensuring a uniform and effective cooling effect. After the position of the main jet head 709 is adjusted, the operator can turn the knob 801 to rotate the threaded rod 819. The threaded rod 819 is threadedly connected to the movable plate 814, allowing the movable plate 814 to slide horizontally within the groove 716 on the lower end face of the extension plate 704. Since connecting plates 813 are rotatably connected to both sides of the movable plate 814, and these connecting plates 813 are rotatably connected to the outer surface via fixed posts 812 and vertical plates 808, as the movable plate 814 moves horizontally, it pulls the connecting plates 813 from a position approaching... As the vertical movement approaches a horizontal position, the connecting plate 813 changes state. This change causes the connecting plate 813, via the fixed column 812 and the vertical plate 808, to pull the ring 811 upwards synchronously on the outer surface of the air pipe 706, and simultaneously drive the vertical plate 808 upwards. Since both sides of the lower end of the vertical plate 808 are connected to levers 809, which are slidably connected to the lever 806 via limiting grooves 810, the upward movement of the vertical plate 808 simultaneously pulls the levers 809 upwards, causing the levers 809 to slide within the limiting grooves 810. During the process, pulling one end of the lever 806 upwards causes it to rotate around the pivot 807. This causes the lever 806 to bend the bellows 803 via the connecting post 805 on the other side. This causes the auxiliary jet head 804 connected to the bellows 803 to rotate downwards towards the main jet head 709, adjusting its tilt angle. This allows the auxiliary jet head 804 to blow compressed air from both sides onto the outer surface of the copper tube body 4 according to its diameter, thus cooling the outer surface of the copper tube body 4. The tilt angle of the auxiliary jet head 804 can be precisely adjusted. When facing copper tube bodies 4 of different diameters, the blowing direction of the auxiliary jet head 804 can be flexibly adjusted to ensure that compressed air can be blown to the surface of the copper tube from both sides at the optimal angle, so as to achieve precise cooling and meet diverse production needs. Moreover, the angle of the auxiliary jet head 804 can be adjusted according to the diameter of the copper tube, and the air is blown to the surface of the copper tube from both sides to cool it down, so that the temperature distribution on the surface of the copper tube is more uniform, effectively reducing internal stress and surface defects caused by uneven temperature, providing good conditions for subsequent processing, thereby improving the overall quality of copper tube products. As the ring 811 slides upward along the air supply pipe 706, adjusting the tilt angle of the auxiliary jet head 804 via the vertical plate 808, lever 809, limiting groove 810, lever 806, rotating shaft 807, and connecting column 805, a fixed column 812 is connected to the side wall of the vertical plate 808. The fixed column 812 is slidably connected to the communicating groove 816 on the side plate 815. A pointer 817 is connected to the side of the fixed column 812 near the communicating groove 816. The pointer 817 corresponds to the scale bar 818 connected to the side wall of the side plate 815. Therefore, as the ring 811 rises, the ring 811 can drive the fixed column 812 to slide upward synchronously within the communicating groove 816 via the vertical plate 808. At this time, the pointer 817 connected to the fixed column 812 will move synchronously, and the scale bar 818 pointed to by the pointer 817 will also change. The operator can observe the scale bar pointed to by the pointer 817. The pointer 818 allows for precise control of the rising distance of the ring 811, enabling the operator to understand how the ring 811 adjusts the tilt angle of the auxiliary jet head 804 during its ascent via the vertical plate 808, lever 809, limit groove 810, lever 806, rotating shaft 807, and connecting column 805. The interaction between the pointer 817 and the scale bar 818 provides operators with an intuitive reference for angle adjustment. By observing the positional changes of the pointer 817 on the scale bar 818, the operator can accurately determine the rising distance of the ring 811, thereby precisely controlling the tilt angle of the auxiliary jet head 804 to meet the stringent requirements of different processes for cooling angles. Furthermore, operators do not need to rely on experience or repeated attempts to adjust the angle of the auxiliary jet head 804; they only need to focus on the scale indicated by the pointer 817 to quickly and accurately adjust the auxiliary jet head 804 to the required angle, greatly simplifying the operation process, saving operating time, and improving work efficiency.
