Description

Technical Field

[0001] This utility model relates to the technical field of deburring equipment for products, and more particularly to a copper strip deburring machine. Background Technology

[0002] Currently, burrs are formed on the edges of copper strips during the slitting process. These burrs need to be removed before the copper strips enter the next production process. The traditional method for removing burrs from copper strips is to use polishing wheels (mostly rubber wheels, etc.) to polish the burrs on both sides of the copper strip. A large amount of dust is generated during the polishing process. This dust will be scattered everywhere in the processing workshop, causing dust pollution and waste. Moreover, the dust is difficult to clean when it is scattered and adheres to the processing equipment, especially when it adheres to the surface of the equipment with oil stains and dead corners. In addition, there are still many problems in the actual use of traditional deburring machines, as follows: (1) After the copper strip is slit, the size of the burrs produced by each batch of copper strip is random, and the size of the burrs of each batch of copper strip products also appears intermittently; therefore, the burrs produced by the copper strip are uncontrollable. After removing the burrs by the traditional polishing method, rework is often required, which wastes manpower and resources, increases costs, and greatly increases the probability of defective products due to low production efficiency; in addition, since the width specifications of each batch of copper strip are different, the existing deburring equipment cannot adapt to the deburring production of copper strips of different sizes, resulting in inaccurate conveying limits during the copper strip conveying process, low deburring accuracy and unsatisfactory effect. (2) Since burrs are mainly removed by polishing, dust is scattered everywhere in the workshop. To protect the health and safety of operators, they must wear masks, dustproof clothing, protective hats and protective shoes in the semi-enclosed workshop to achieve all-round protection and prevent dust from coming into contact with the human body and causing discomfort. However, such protection is extremely inconvenient in the processing and production process. It is not convenient to move the protective clothing, and it is difficult to operate it. Moreover, it is difficult to make the protective clothing fit the body size of each operator. In addition, most of the protective items are disposable consumables. Over time, the wear and tear of protective items is huge, which increases the production cost. Finally, although the protective items can protect the operators to a certain extent, dust and other debris will still adhere to the dustproof clothing. When the dustproof clothing is taken off, there is still a risk that the operators will inhale the dust. Therefore, it fails to effectively protect the operators. (3) The main way to recycle the waste powder generated during the polishing of copper strip burrs is to use a vacuum cleaner. Some powder that adheres to oil stains or oily areas when it is floating is difficult to recycle and clean. It is necessary to use a scraper to scrape it off. Especially in some dead corners, neither the vacuum cleaner nor the scraper can clean it clean. This makes it difficult to recycle the powder cleanly, resulting in pollution and waste.

[0003] In addition, existing patents such as Chinese Patent No. 202422740470.3, "A Deburring Device for Copper Strips," which only uses grinding discs to remove burrs; Chinese Patent No. 202421746311.8, "A Deburring and Shearing Device for Irregularly Shaped Copper Strips," which only uses a grinding table to remove burrs; Chinese Patent No. 202420724414.8, "A Uniformly Grinded Deburring Device for Copper Strips," which uses a grinding disc to remove burrs; Chinese Patent No. 202123305008.3, "A Deburring Device for Copper Strips," which uses a grinding mechanism to remove burrs; and Chinese Patent No. 202122020094.7, "A Deburring Device for Copper Strips," which uses an edge grinding device to remove burrs, basically only use grinding methods to remove copper strip burrs, which is difficult to solve the problems of excessive dust and low efficiency mentioned above.

[0004] Therefore, it is necessary to make certain improvements to the existing copper strip deburring machine to realize a copper strip deburring machine that is suitable for convenient removal of copper strip burrs of different sizes, basically prevents dust splashing, and improves the production efficiency of burr removal. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a copper strip deburring machine. This machine is used for deburring copper strips and employs a movable adjustable fixed shaft assembly to input the copper strip, allowing for adjustable spacing of the input channel. This facilitates the input of copper strips of different specifications and improves the applicability of copper strips of different sizes to this deburring machine. After the copper strip is fed into the deburring machine, the burr blade assembly scrapes off the burrs on both sides of the copper strip, forming burr waste in the form of copper wire. This waste copper wire can be easily recycled by placing a plastic box or bag at the copper wire collection point. After burr removal, further fine grinding, polishing, leveling, and straightening processes are performed to obtain a high-quality copper strip product with high deburring efficiency and excellent product quality. Finally, because the deburring machine has a closed structure, dust is avoided during the fine grinding and polishing process inside the deburring machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a copper strip deburring machine, including a deburring machine housing, on which are provided a movable adjustable fixed shaft assembly for stably conveying copper strips of different sizes and specifications, a deburring knife assembly for removing burrs formed on the edges of the copper strip during the slitting process, a grinding and polishing assembly for grinding and polishing the copper strip after burr removal, a leveling assembly for leveling the ground and polished copper strip, and a straightening assembly for straightening and collecting the leveled copper strip.

[0007] The deburring tool assembly includes a deburring fixing frame fixedly installed on the side wall of the deburring machine housing at the material inlet end, a deburring tool mounting plate installed on the deburring fixing frame, a copper strip conveying limiting groove formed in the longitudinal direction of the deburring tool mounting plate to limit the conveying of the input copper strip on both sides, and an upper deburring tool and a lower deburring tool installed on the top of the deburring tool mounting plate and arranged one in front of the other to remove and cut off the burrs on each side edge of the copper strip.

[0008] The grinding and polishing assembly includes a left grinding wheel and a right grinding wheel arranged in front of and behind each other to grind the two edges of the copper strip after burrs are removed, and a first polishing sandpaper wheel and a second polishing sandpaper wheel arranged in front of and behind each other and set at different heights to polish the copper strip.

[0009] Furthermore, the fixed shaft assembly includes a left fixed wheel group and a right fixed wheel group mounted on the deburring fixing frame and spaced apart. Both the left and right fixed wheel groups can be adjusted synchronously inward or outward to adjust the distance between them. Both the left and right fixed wheel groups are composed of multiple movable guide wheels.

[0010] Furthermore, the leveling assembly includes a front leveling wheel located in front of the first polishing sandpaper wheel, a middle leveling wheel located behind the second polishing sandpaper wheel, a front fixed wheel and a rear fixed wheel located behind the middle leveling wheel for fixing and conveying the copper strip, and a rear leveling wheel located behind the rear fixed wheel.

[0011] Furthermore, the straightening assembly includes a straightening bracket and multiple straightening shafts evenly distributed and arranged on the straightening bracket.

[0012] Furthermore, both the upper and lower burr blades are tungsten carbide blades with the cutting edge facing downwards, and both the upper and lower burr blades are inclined upwards.

[0013] Furthermore, the grinding and polishing assembly also includes a grinding bracket, which has an internal copper strip through-hole that allows the copper strip to pass through. The grinding bracket has inwardly grooved sides that communicate with the side of the internal copper strip through-hole to form grinding wheel insertion slots exposed on the side of the internal copper strip through-hole. The left grinding wheel and the right grinding wheel are respectively placed in their respective grinding wheel insertion slots.

[0014] Furthermore, the left grinding wheel is connected and driven to rotate by a left drive motor, the right grinding wheel is connected and driven to rotate by a right conventional motor, and the first polishing sandpaper wheel is connected and driven to rotate by a polishing drive motor. The first polishing sandpaper wheel and the second polishing sandpaper wheel rotate synchronously through a sandpaper wheel belt.

[0015] Furthermore, the outer circumferential surfaces of the front leveling wheel, middle leveling wheel, and rear leveling wheel are all recessed with leveling ring grooves that allow the copper strip to be wound in and limit the two edges of the copper strip.

[0016] Furthermore, the burrs on both edges of the copper strip are removed by the upper and lower burr cutters, and the cut edges of the copper strip are then chamfered.

[0017] Furthermore, the deburring machine housing is a closed structure.

[0018] In summary, this utility model's copper strip deburring machine is used for deburring copper strips. It employs a movable, adjustable fixed shaft assembly to input the copper strip, allowing for adjustable spacing in the input channel. This facilitates the input of copper strips of different specifications, improving the suitability of copper strips of varying sizes for this deburring machine. After the copper strip is fed into the deburring machine, the deburring blade assembly scrapes off the burrs on both edges of the copper strip, forming copper wire-like waste material. This waste copper wire can be easily collected by placing a plastic box or bag at the collection point. After burr removal, further finer processes such as grinding, polishing, leveling, and straightening are performed to obtain high-quality copper strip products with high deburring efficiency and excellent product yield. Finally, because the deburring machine's outer shell is a closed structure, dust generation during the fine grinding and polishing process inside the copper strip deburring machine is prevented.

[0019] The beneficial effects of this copper strip deburring machine are:

[0020] 1. Quality controllable: Because the gap of the input channel can be adjusted to accommodate copper strips of different widths, and the gap between the blade of the deburring blade and the edge of the copper strip is fixed, the deburred state is copper wire state, which can completely remove the burrs. It will not be impossible to completely remove the burrs due to the randomness of the size of the burrs in the incoming copper strip.

[0021] 2. Convenient waste recycling: The waste is transformed from dust into copper wire. Simply place a plastic box or bag under the copper wire generated by the copper strip deburring machine to collect the copper wire. This will not generate dust that contaminates the deburring machine's workbench and other parts.

[0022] 3. Improved workshop environment: With the elimination of dust, the workshop has been changed from a semi-enclosed environment to a fully open one, which further reduces the impact of noise, reduces the number of processes, and saves on consumables;

[0023] 4. Improve the quality of copper strip products: Since the burrs are basically removed by using a deburring knife, and then the deburred surface is finely ground and polished with a grinding and polishing wheel, the deburred surface is made smooth, which improves the overall quality of the copper strip.

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in Embodiment 1, a copper strip deburring machine includes a deburring machine housing 18. The housing is equipped with a movable, adjustable, fixed shaft assembly 19 for stable conveying of copper strips of different sizes and specifications; a deburring knife assembly 20 for removing burrs formed on the edges of the copper strip during slitting; a grinding and polishing assembly 21 for grinding and polishing the deburred copper strip; a leveling assembly 22 for leveling the ground and polished copper strip; and a straightening assembly 23 for straightening and collecting the leveled copper strip. This copper strip deburring machine consists of five main components: the movable, adjustable, fixed shaft assembly, the deburring knife assembly, the grinding and polishing assembly, the leveling assembly, and the straightening assembly. The burred copper strip is first stably fed into the deburring machine housing via a movable and adjustable fixed shaft assembly. Then, the burrs on both sides of the copper strip are removed by the deburring blade assembly, and the waste material removed from the copper strip is copper wire with burrs. After the burrs are removed, the copper strip enters the grinding and polishing assembly for grinding and polishing. This achieves secondary grinding and removal of some residual burrs and fine grinding and polishing of the cut surface of the copper strip to achieve a smooth surface. Before and after grinding and polishing, corresponding leveling processes are performed to make the copper strip flat. Finally, the copper strip is straightened and collected by the straightening assembly, completing the entire deburring process of the copper strip. This process can reduce the amount of dust generated during deburring. The dust generated by traditional techniques is transformed into copper wire, reducing environmental pollution and improving product quality. The copper wire is also easy and quick to recycle. In addition, the grinding and polishing process in this embodiment is a fine grinding and polishing process with a short grinding and polishing time. Because it is a fine grinding and polishing process, the amount of dust generated is very small and it is very easy to recycle, so it will not generate a large amount of dust.

[0032] The deburring tool assembly includes a deburring fixing frame 24 fixedly installed at the feed end of the side wall of the deburring machine housing, a deburring tool mounting plate 25 installed on the deburring fixing frame, a copper strip conveying limiting groove 26 with a recessed setting along the longitudinal direction of the deburring tool mounting plate to limit the conveying of the input copper strip on both sides, and an upper deburring tool 2 and a lower deburring tool 3 installed on the top of the deburring tool mounting plate and set one in front of the other to remove and cut off the burrs on each side edge of the copper strip. The deburring bracket has a similar "Z"-shaped structure, serving as a support for the entire deburring knife assembly. The deburring knife mounting plate is used to install the upper and lower deburring knives, which are positioned at the front and rear. The working principle of the deburring knife assembly is as follows: the copper strip with burrs enters the copper strip conveying limiting groove smoothly. The bottom and two outer sides of the copper strip are respectively attached to the bottom and two outer walls of the copper strip conveying limiting groove. This creates a stable and controlled conveying effect for the copper strip within the groove, achieving the purpose of stable and smooth conveying. When the copper strip passes through the upper and lower deburring knives, the upper deburring knife removes the burrs on one side of the copper strip, forming a thin, long burr wire. The lower deburring knife also removes the burrs on one side of the copper strip, similarly forming a thin, long burr wire. In this way, the removal of burrs from the copper strip is essentially completed.

[0033] The polishing assembly includes a left polishing wheel 6 and a right polishing wheel 7, arranged one in front of the other, to polish the two edges of the copper strip after burr removal, and a first polishing sandpaper wheel 11 and a second polishing sandpaper wheel 12, arranged one in front of the other and set at different heights, to polish the copper strip. After the burrs on the copper strip are removed, when it passes through the polishing assembly, the left and right polishing wheels first perform fine polishing on the outer edges of the copper strip to remove residual small burrs and create a smooth surface on the outer edges. Then, as the copper strip passes through the first and second polishing sandpaper wheels, the cut surface is finely polished, also creating a smooth surface. This achieves fine polishing of both the cut surface and the outermost edge of the copper strip, resulting in a smooth polished surface, improving the efficiency of burr removal and the overall quality of the product.

[0034] In this embodiment 1, the fixed shaft assembly includes a left fixed wheel group 1 and a right fixed wheel group 27 mounted on the deburring fixing frame and staggered at intervals. Both the left and right fixed wheel groups can be adjusted synchronously inward or outward to adjust the distance between them. Both the left and right fixed wheel groups are composed of multiple movable guide wheels, and the movable guide wheels of the left and right fixed wheel groups are spaced apart and do not overlap, which ensures that each position of the side edge of the copper strip is guided by movable guide wheels when it is being conveyed, thus achieving the purpose of stable conveying without derailment.

[0035] In this embodiment 1, the leveling assembly includes a front leveling wheel 10 located in front of the first polishing sandpaper wheel, a middle leveling wheel 13 located behind the second polishing sandpaper wheel, a front fixed wheel 14 and a rear fixed wheel 15 located behind the middle leveling wheel for fixed conveying of the copper strip, and a rear leveling wheel 16 located behind the rear fixed wheel. Before entering the first polishing sandpaper wheel for polishing, the copper strip first passes through the front leveling wheel for leveling. After the copper strip passes through the second polishing sandpaper wheel for polishing, it passes through the middle leveling wheel for secondary leveling. Then, the copper strip enters the front and rear fixed wheels for stable fixed conveying, without guaranteeing that the copper strip will not deviate during conveying. Finally, it enters the rear leveling wheel for a third leveling, ensuring excellent overall leveling effect of the copper strip.

[0036] In this embodiment 1, the straightening assembly includes a straightening bracket 28 and multiple straightening shafts 17 evenly distributed and arranged on the straightening bracket. After the copper strip has been leveled, it enters the straightening bracket and is straightened by the multiple straightening shafts before being collected, thus completing the entire straightening and collecting process.

[0037] In this embodiment 1, both the upper and lower burr cutters are tungsten carbide blades with the cutting edge facing downwards, and both are angled upwards. The use of tungsten carbide for both blades gives them high hardness, wear resistance, heat resistance, corrosion resistance, strength, and toughness, making them suitable for long-term, high-intensity continuous cutting and ensuring a long service life for the entire burr cutter. The upward angle of the upper and lower burr cutters allows space between the cutting edge and the top surface of the copper strip for the copper strip to pass through, and also allows the burrs at the edge of the copper strip to be cut off by the cutting edge, forming copper wire-like structures.

[0038] In this embodiment 1, as Figure 5 As shown, the polishing assembly also includes a polishing bracket 4. The polishing bracket has an internal copper strip groove 29 that allows the copper strip to pass through. On both sides of the polishing bracket are inwardly recessed grooves that communicate with the sides of the internal copper strip groove, forming polishing wheel insertion slots 30 where the sides of the internal copper strip groove are exposed. The left and right polishing wheels are respectively placed in their corresponding polishing wheel insertion slots. After the copper strip is deburred by the upper and lower deburring blades, it passes through the grooves of the internal copper strip groove into the polishing bracket. When the copper strip passes through the polishing wheel insertion slots, the side of the copper strip edge will be exposed through these slots. In this way, the surfaces of the left and right polishing wheels can finely polish the edge of the copper strip and remove any small burrs that have not been completely cut off, forming a smooth surface.

[0039] In this embodiment 1, the left grinding wheel is connected and driven to rotate by a left drive motor 5, and the right grinding wheel is connected and driven to rotate by a right conventional motor 9. The first polishing sandpaper wheel is connected and driven to rotate by a polishing drive motor 8. The first and second polishing sandpaper wheels rotate synchronously via a sandpaper wheel belt 31. The corresponding grinding wheels are driven by their respective drive motors, ensuring the independence of the grinding action; and the synchronous rotation between the first and second polishing sandpaper wheels is achieved by connecting them via a sandpaper wheel belt.

[0040] In this embodiment 1, the outer circumferential surfaces of the front leveling wheel, the middle leveling wheel, and the rear leveling wheel are all recessed with leveling ring grooves 32 that allow the copper strip to be wound in and limit the two edges of the copper strip.

[0041] In this embodiment 1, the burrs on both edges of the copper strip are removed by the upper and lower burr cutters, and the cut edges of the copper strip are then chamfered.

[0042] In this embodiment 1, the deburring machine housing is a closed structure. The closed structure of the deburring machine housing prevents dust and other particles from flying, further ensuring a clean workshop environment and making it easier to collect and clean the tiny metal shavings from fine grinding and polishing.

[0043] The working principle of this copper strip deburring machine is as follows: The copper strip is threaded between the left and right fixed roller sets. These sets are movable, and the distance between them is adjustable to accommodate copper strips of different specifications. After threading between the roller sets, the copper strip passes through an upper deburring blade to remove burrs on one side, and then through a lower deburring blade to remove burrs on the other side. The removed burrs, in the form of copper wires, fall into a collection box for collection. This process completely removes burrs formed on the edges of the copper material during the slitting process, resulting in a chamfered edge on the copper strip. After deburring, the copper strip is then threaded into a grinding bracket. The copper strip is inserted into the groove, and then the edges of the copper strip exposed in the groove are polished by the left and right grinding wheels to completely remove the small burrs and burrs that cannot be properly removed by the burr removal tool. Then, the copper strip is initially leveled by the front leveling wheel. The copper strip is then polished by passing through the first and second polishing sandpaper wheels from top to bottom. The copper strip is then leveled by the middle leveling wheel. The copper strip is then fixed by the front and rear fixing wheels. The copper strip is leveled again by the rear leveling wheel. Finally, the copper strip is straightened and collected by the straightening shaft, completing the deburring process of the copper strip.

[0044] In this embodiment 1, the copper strip deburring machine is used to deburr copper strips. It employs a movable, adjustable fixed shaft assembly to input the copper strip, allowing for adjustable spacing of the input channel. This facilitates the input of copper strips of different specifications, improving the applicability of copper strips of varying sizes to this deburring machine. After the copper strip is fed into the deburring machine, the deburring blade assembly scrapes off the burrs on both sides of the copper strip, forming copper wire-like waste material. This waste copper wire can be easily collected by placing a plastic box or bag at the copper wire collection point. After burr removal, further finer processes such as grinding, polishing, leveling, and straightening are performed to obtain a high-quality copper strip product with high deburring efficiency and excellent product yield. Finally, because the deburring machine's outer shell is a closed structure, dust generation during the fine grinding and polishing process inside the copper strip deburring machine is prevented.

[0045] The beneficial effects of this copper strip deburring machine are:

[0046] 1. Quality controllable: Because the gap of the input channel can be adjusted to accommodate copper strips of different widths, and the gap between the blade of the deburring blade and the edge of the copper strip is fixed, the deburred state is copper wire state, which can completely remove the burrs. It will not be impossible to completely remove the burrs due to the randomness of the size of the burrs in the incoming copper strip.

[0047] 2. Convenient waste recycling: The waste is transformed from dust into copper wire. Simply place a plastic box or bag under the copper wire generated by the copper strip deburring machine to collect the copper wire. This will not generate dust that contaminates the deburring machine's workbench and other parts.

[0048] 3. Improved workshop environment: With the elimination of dust, the workshop has been changed from a semi-enclosed environment to a fully open one, which further reduces the impact of noise, reduces the number of processes, and saves on consumables;

[0049] 4. Improve the quality of copper strip products: Since the burrs are basically removed by using a deburring knife, and then the deburred surface is finely ground and polished with a grinding and polishing wheel, the deburred surface is made smooth, which improves the overall quality of the copper strip.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the structure of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
