[0002] In the field of modern industrial manufacturing, aluminum coils are widely used in many industries such as aerospace, automotive manufacturing, electronic equipment, and building decoration due to their excellent properties such as light weight, high strength, and good corrosion resistance. Turning processing, as one of the key processes for aluminum coil forming and finishing, can effectively achieve control of the dimensional accuracy of aluminum coils, optimization of surface quality, and processing of specific structural features. However, there are still many problems to be solved in the existing aluminum coil turning technology:

[0003] The prior art does not effectively shape the edges of the aluminum strip before turning. There are small deformations, unevenness, or bending defects at the edges of the aluminum strip, which will lead to problems such as uneven thickness, excessive or insufficient local turning in subsequent turning. The prior art cannot achieve multi-dimensional dynamic processing, resulting in low edge finishing efficiency. It is impossible to complete multiple processing operations in one processing process and requires multiple processes to achieve a certain finishing effect, increasing the processing procedures and time, and reducing the processing efficiency of aluminum strip edge finishing;

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The present invention is provided with a shaping roller before turning. When the aluminum strip passes through the shaping roller, the electric heating rods inside the shaping roller and the electric heating blocks inside the trimming frame generate heat to adjust the material properties of the aluminum strip, making the aluminum strip easier to be shaped. The shaping roller made of stainless steel and with a suitable length can effectively shape the entire width direction of the aluminum strip, eliminate minor deformations and unevenness, provide a good foundation for the subsequent turning and grinding processes, improve the turning accuracy, make the edge dimensions and shapes of the aluminum strip more in line with the design requirements, and at the same time improve the turning surface quality, making the surface smoother and the roughness reduced.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 9 shown, the present invention provides an aluminum coil edge finishing mechanical device, including a base frame 1, on which an uncoiling roller 2 is rotatably installed, an aluminum strip 3 is wound on the uncoiling roller 2, and an aluminum coil is formed after the aluminum strip 3 is wound on the uncoiling roller 2;

[0034] A guiding roller 15 is rotatably installed on the base frame 1 at a position adjacent to the uncoiling roller 2;

[0035] A microcontroller 13 and an unwinding motor are installed on the base frame 1, and the output shaft end of the unwinding motor is fixedly connected to the uncoiling roller 2;

[0036] Two tensioning systems for elastically tensioning the aluminum strip 3 are provided on the base frame 1;

[0037] The tensioning system includes a tensioning frame 29. A set of T-shaped guide rods 30 are installed on the tensioning frame 29. Each T-shaped guide rod 30 is slidably connected to the base frame 1. A tensioning spring 31 is sleeved on the T-shaped guide rod 30 at the position corresponding to between the base frame 1 and the tensioning frame 29. A tensioning roller 32 that fits the aluminum strip 3 is rotatably installed on the tensioning frame 29;

[0038] During the edge finishing process of the aluminum coil, the uncoiling roller 2 releases the aluminum strip 3. After passing through the guide roller 15, the aluminum strip 3 fits the tensioning roller 32. The T-shaped guide rod 30 on the tensioning frame 29 can slide on the base frame 1. The tensioning spring 31 is sleeved on the T-shaped guide rod 30, and its elastic force enables the tensioning roller 32 to exert an elastic tensioning effect on the aluminum strip 3. This elastic tensioning can effectively avoid problems such as slack and wrinkles of the aluminum strip 3 during transportation, ensure that the aluminum strip 3 is in a stable tensioned state in the subsequent finishing process, provide a good foundation for subsequent shaping, turning, and grinding operations, and improve the finishing quality;

[0039] A power system is provided on the base frame 1 at the position corresponding to between the two tensioning systems. A vertical vibration frame 4 that can reciprocate vertically is drivingly installed on the power system. A trimming frame 5 that reciprocates along the axis direction of the uncoiling roller 2 is drivingly installed on the vertical vibration frame 4. The displacement stroke and displacement frequency of the vertical vibration frame 4 and the trimming frame 5 change cyclically;

[0040] The power system includes a servo motor 17 installed on the base frame 1. The output shaft end of the servo motor 17 is installed with a first key shaft 18. A second key shaft 19 and a vertical screw 20 are respectively rotatably installed on the base frame 1. A second synchronous belt is drivingly connected between the second key shaft 19 and the vertical screw 20;

[0041] The vertical screw 20 is drivingly connected to the vertical vibration frame 4. A first hollow shaft 21 driven by the first key shaft 18, a second hollow shaft 22 linked with the second key shaft 19, and a longitudinal screw 23 are respectively rotatably installed on the vertical vibration frame 4;

[0042] A first hollow groove with both ends open and slidably connected to the first key shaft 18 is opened inside the first hollow shaft 21. A second hollow groove with both ends open and fixedly slidably connected to the second key shaft 19 is fixedly opened inside the second hollow shaft 22. The cross-sections of the first hollow groove, the second hollow groove, the first key shaft 18, and the second key shaft 19 are all regular hexagons. A straight shaft 28 is rotatably installed on the vertical vibration frame 4. A third synchronous belt is drivingly connected between the straight shaft 28 and the second hollow shaft 22. First bevel gears are installed on both the straight shaft 28 and the longitudinal screw 23, and the two first bevel gears are orthogonally meshed;

[0043] A large angular sector gear 24 and a small angular sector gear 25 are respectively mounted on a first hollow shaft 21. Two symmetrically arranged non-transmission sections are provided on the first hollow shaft 21 at positions corresponding to between the large angular sector gear 24 and the small angular sector gear 25;

[0044] The longitudinal screw 23 is in transmission connection with the trimming frame 5. Steering torsion springs 26 are provided at the rotational connection of the vertical screw 20 with the base frame 1 and at the rotational connection of the longitudinal screw 23 with the vertical vibration frame 4. Two differential gears 27 are mounted on the second hollow shaft 22, and the two differential gears 27 are respectively in transmission connection with the large angular sector gear 24 and the small angular sector gear 25;

[0045] The central angle corresponding to the large angular sector gear 24 is 180°, the central angle corresponding to the small angular sector gear 25 is 110°, the central angles corresponding to the two non-transmission sections are both 35°, the radius of the large angular sector gear 24 is 1.7 times the radius of the small angular sector gear 25, the radius of the large angular sector gear 24 is 13 times the radius of a corresponding differential gear 27, and the radius of the small angular sector gear 25 is 10 times the radius of the other corresponding differential gear 27;

[0046] After the servo motor 17 is started, the first key shaft 18 mounted on the output shaft end thereof starts to rotate. At the same time, a second key shaft 19 and a vertical screw 20 are respectively rotatably mounted on the base frame 1. The second key shaft 19 and the vertical screw 20 are in transmission connection through a second synchronous toothed belt. When the servo motor 17 drives the first key shaft 18 to rotate, it will indirectly drive the second key shaft 19 to rotate, and then the vertical screw 20 will be driven to rotate through the second synchronous toothed belt. The vertical screw 20 is in transmission connection with the vertical vibration frame 4, and the rotation of the vertical screw 20 will drive the vertical vibration frame 4 to make reciprocating displacement in the vertical direction;

[0047] In this process, a steering torsion spring 26 is provided at the rotational connection of the vertical screw 20 with the base frame 1. The function of the steering torsion spring 26 is to provide a certain elastic resistance and restoring force during the rotation of the vertical screw 20. When the vertical screw 20 rotates forward to make the vertical vibration frame 4 displace upward, the steering torsion spring 26 will store elastic potential energy;

[0048] When the vertical screw 20 rotates reversely, the steering torsion spring 26 releases the elastic potential energy, assists the vertical vibration frame 4 to displace downward, and affects the displacement stroke and frequency of the vertical vibration frame 4 through its elastic characteristics, so that it forms a cyclic change;

[0049] The first key shaft 18 drives the first hollow shaft 21 to rotate. When the first hollow shaft 21 rotates, the large-angle fan gear 24 and the small-angle fan gear 25 will rotate accordingly. Due to the existence of the non-transmission section, the large-angle fan gear 24 and the small-angle fan gear 25 will periodically engage and disengage with the differential gear 27 on the second hollow shaft 22. When the large-angle fan gear 24 or the small-angle fan gear 25 engages with the differential gear 27, it will drive the second hollow shaft 22 to rotate. The second hollow shaft 22 drives the longitudinal screw 23 to rotate through a series of transmission components. The longitudinal screw 23 is connected to the trimming frame 5. The rotation of the longitudinal screw 23 will drive the trimming frame 5 to move back and forth along the axis of the unwinding roller 2.

[0050] At the same time, a steering torsion spring 26 is also provided at the rotation connection between the longitudinal screw 23 and the vertical vibration frame 4. The steering torsion spring 26 also provides elastic resistance and restoring force during the rotation of the longitudinal screw 23, affecting the displacement stroke and frequency of the trimming frame 5, so that it forms a cyclic change like the vertical vibration frame 4;

[0051] The displacement stroke and displacement frequency of the vertical oscillating frame 4 and the trimming frame 5 are cyclically changed, so that the shaping roller 6 installed on the trimming frame 5 and the finishing assembly installed in the turning frame 7 on the vertical oscillating frame 4 can process the edge of the aluminum strip 3 at different positions and frequencies;

[0052] At different parts of the edge of the aluminum strip 3, according to the degree of defects and material properties, the shaping roller 6 can shape the aluminum strip 3 at different pressures and positions, and the finishing component can perform turning and grinding operations at different angles and forces. This can more effectively remove burrs and uneven defects on the edge of the aluminum strip 3, making the edge surface of the aluminum strip 3 smoother and flatter, thereby improving the finishing quality of the edge of the aluminum strip 3;

[0053] Through the cyclically changing displacement stroke and frequency, the shaping roller 6, the turning tool 10, the turning roller 11 and the grinding roller 12 can complete multiple processing operations in one processing process, reducing the processing steps and time. In one reciprocating displacement process, the shaping roller 6 can shape the edge of the aluminum strip 3 multiple times, and the finishing assembly can turn and grind the edge of the aluminum strip 3 multiple times, thereby improving the processing efficiency of the edge finishing of the aluminum strip 3;

[0054] During production, transportation, or storage, the edges of the aluminum strip 3 may be slightly deformed, uneven, or bent. If not shaped, subsequent turning may result in uneven thickness, over- or under-cutting of parts, affecting the finishing quality and accuracy. Furthermore, the uneven edges of the aluminum strip 3 may cause unstable contact between the turning tool 10 and the aluminum strip 3, resulting in vibration and jitter, which not only affects the surface finish of the turning, but also aggravates wear of the turning tool 10 and may even damage the turning tool 10, increasing production costs.

[0055] Meanwhile, the turning process requires the material to have a certain flatness and regularity. Shaping can make the aluminum strip 3 better meet the turning requirements. By shaping, the turning accuracy is improved, enabling the turning tool 10 to cut more accurately along the predetermined trajectory, reducing errors, and making the edge dimensions and shape of the aluminum strip 3 more in line with the design requirements;

[0056] Through pre-shaping, the surface quality of turning is improved. The stable contact reduces vibration and runout, making the surface smoother and the roughness lower;

[0057] Meanwhile, shaping extends the service life of the turning tool 10. Stable turning reduces wear and damage, lowers the tool replacement frequency and cost, and reduces production downtime;

[0058] Moreover, the realization of the pre-shaping effect enhances the consistency of the finishing effect, making the processing effects of all parts more uniform, and improving the stability and reliability of the finishing quality;

[0059] Two shaping rollers 6 are rotatably installed on the trimming frame 5. Both shaping rollers 6 are made of stainless steel, and the length of the shaping roller 6 is 1.4 times the width of the aluminum strip 3;

[0060] The shaping roller 6 is internally provided with a heating rod;

[0061] A heating block 16 is installed inside the trimming frame 5. The heating temperatures of the heating rod and the heating block 16 are both 450 °C;

[0062] Both the heating block 16 and the heating rod are internally provided with temperature sensors, which are linked with the microcontroller 13 for precise temperature control of the heating block 16 and the heating rod;

[0063] When the aluminum strip 3 passes through the shaping roller 6, the heating rod inside the shaping roller 6 and the heating block 16 inside the trimming frame 5 start to heat up, and the heating temperature is 450 °C. At this temperature, the material properties of the aluminum strip 3 will change, and its hardness and toughness will be adjusted, making the aluminum strip 3 easier to shape. The shaping roller 6 is made of stainless steel and has a length of 1.4 times the width of the aluminum strip 3, which can effectively shape the entire width direction of the aluminum strip 3. By heating and shaping the aluminum strip 3, some minor deformations and unevenness at the edge of the aluminum strip 3 can be eliminated, making the edge of the aluminum strip 3 more regular, providing a better basis for subsequent turning and grinding processes;

[0064] A turning frame 7 is fixedly installed on the vertical vibration frame 4. A distance adjusting component and a reversing shaft 8 are installed on the turning frame 7. The reversing shaft 8 is driven by a power system and periodically changes the rotation direction and speed. Two symmetrically arranged and distance-adjustable turning tables 9 are drivingly installed on the distance adjusting component, and a fine trimming component is installed on the two turning tables 9;

[0065] The finishing component includes a turning tool 10 installed on a turning table 9, a turning roller 11 and a grinding roller 12 rotatably connected to the turning table 9. A first synchronous toothed belt is drivingly connected between the turning roller 11 and the grinding roller 12, and the grinding roller 12 is driven by a reversing shaft 8;

[0066] At a position corresponding to the lower part of the turning roller 11 on the inner wall of the base frame 1, a waste storage drawer 14 with an open top is snap-fitted;

[0067] Steel wire brush hairs are evenly distributed on the grinding roller 12. The thickness of the steel wire brush hairs is 2.5 cm. The heights of both the grinding roller 12 and the turning roller 11 are 7 times the thickness of the aluminum strip 3. The axes of both the grinding roller 12 and the turning roller 11 are perpendicular to the horizontal plane;

[0068] A third hollow shaft 34 is rotatably installed on the turning table 9. A third hollow groove with both ends open and slidably connected to the reversing shaft 8 is fixedly opened inside the third hollow shaft 34. The cross-sections of both the third hollow groove and the reversing shaft 8 are regular hexagons. Second bevel gears are installed on both the grinding roller 12 and the third hollow shaft 34, and the two second bevel gears are orthogonally meshed. A belt connection section 35 is provided on the reversing shaft 8, and an elastic tension transmission belt 36 is drivingly connected between the belt connection section 35 and the longitudinal screw 23;

[0069] The elastic tension transmission belt 36 is made of rubber. The elastic tension transmission belt 36 can elastically compensate for the displacement of the trimming frame 5. The length of the belt connection section 35 is 8 times the width of the elastic tension transmission belt 36;

[0070] Anti-slip patterns are added to the surface of the elastic tension transmission belt 36;

[0071] When the aluminum strip 3 passes through the turning frame 7, the distance adjusting component can adjust the distance between the two turning tables 9 according to the actual width of the aluminum strip 3 to meet the finishing requirements of aluminum strips 3 of different specifications. The power system drives the reversing shaft 8 to rotate. The reversing shaft 8 periodically changes the rotation direction and speed. The longitudinal screw 23 is driven to rotate through the belt connection section 35 and the elastic tension transmission belt 36. The grinding roller 12 is driven to rotate through the third hollow shaft 34 and the second bevel gear. The turning roller 11 is driven to rotate by the grinding roller 12 through the first synchronous toothed belt. The turning tool 10 on the turning table 9 performs turning operations on the edges of the aluminum strip 3 to remove the excess parts and burr defects on the edges of the aluminum strip 3;

[0072] The turning roller 11 further performs fine processing on the surface after turning, and the wire brush bristles evenly distributed on the grinding roller 12 grind the surface after turning and turning roller 11 processing, so that the edge surface of the aluminum strip 3 is smoother. At the same time, the waste storage drawer 14 connected to the inner wall of the base frame 1 corresponding to the position below the turning roller 11 can collect waste generated during the turning and grinding process, and keep the working environment clean. The elastic tensioning transmission belt 36 is made of rubber material, which can elastically compensate for the displacement of the trimming frame 5 to ensure the stability of the transmission. Compared with the existing technology, the turning and grinding assembly can perform comprehensive and fine processing on the edge of the aluminum strip 3 through the coordinated action of the turning tool 10, the turning roller 11 and the grinding roller 12, thereby improving the finishing quality of the edge of the aluminum strip 3, and the waste collection design is more environmentally friendly and humane.

[0073] After the servo motor 17 is started, the first key shaft 18 at its output shaft end rotates, driving the first hollow shaft 21 to rotate. The large-angle sector gear 24 and the small-angle sector gear 25 on the first hollow shaft 21 periodically engage with the differential gear 27 on the second hollow shaft 22. Due to the different radii of the large-angle sector gear 24 and the small-angle sector gear 25 and the existence of the non-transmission section, the speed and direction of the second hollow shaft 22 change periodically, and are transmitted to the reversing shaft 8 through the power system to achieve its reciprocating speed change;

[0074] The reciprocating change of the rotation direction of the grinding roller 12 and the turning roller 11 is related to the movement of the reversing shaft 8. The rotation direction and speed change of the reversing shaft 8 are transmitted to the grinding roller 12 through the power system. The turning roller 11 and the grinding roller 12 are connected by the first synchronous toothed belt drive, and the rotation direction changes accordingly.

[0075] The grinding roller 12 and the turning roller 11 reciprocate and vibrate in a direction perpendicular to the aluminum strip 3 because the vertical screw 20 in the power system rotates under the drive of the second key shaft 19 and the second synchronous toothed belt, causing the vertical vibration frame 4 to move back and forth in the vertical direction. The turning frame 7 is fixed on the vertical vibration frame 4, thereby driving the grinding roller 12 and the turning roller 11 installed on the turning table 9 to reciprocate and vibrate in a direction perpendicular to the aluminum strip 3.

[0076] By changing the rotation speed in cycles, burrs and uneven defects can be removed more effectively, making the edge surface of the aluminum strip 3 smoother and flatter, thereby improving the finishing quality;

[0077] The reciprocating rotation of the grinding roller 12 and the turning roller 11 can process the edge of the aluminum strip 3 from different directions, avoiding the problems of lines and unevenness caused by single rotation processing, and further improving the surface quality of the edge of the aluminum strip 3;

[0078] The reciprocating vibration in the direction perpendicular to the aluminum strip 3 enables the grinding roller 12 and the turning roller 11 to contact the edge of the aluminum strip 3 more comprehensively, and can effectively process some tiny defects hidden inside the edge, thereby enhancing the finishing effect;

[0079] This complex motion mode can complete multiple processing operations in one processing process, reducing the processing procedures and time, and improving the efficiency of the edge finishing of the aluminum strip 3;

[0080] The distance adjustment component includes a distance adjustment screw 33 rotatably connected to the turning frame 7. A clamping motor is installed on the side of the turning frame 7, and the output shaft end of the clamping motor is fixedly connected to the distance adjustment screw 33. The distance adjustment screw 33 is respectively provided with a forward thread section and a reverse thread section, and the forward thread section and the reverse thread section are respectively in transmission connection with two turning tables 9;

[0081] When performing edge finishing on aluminum strips 3 of different widths, start the clamping motor on the side of the turning frame 7. The clamping motor drives the distance adjustment screw 33 to rotate. The forward thread section and the reverse thread section on the distance adjustment screw 33 are respectively in transmission connection with two turning tables 9. When the distance adjustment screw 33 rotates, the two turning tables 9 will approach or move away from each other according to the rotation direction of the screw, so as to realize the adjustment of the distance between the two turning tables 9. This adjustable distance design enables the aluminum coil edge finishing mechanical device to adapt to the finishing requirements of aluminum strips 3 of different specifications, improving the versatility and applicability of the device;

[0082] The tail of the base frame 1 is provided with a clamping and discharging system.

[0083] The clamping and discharging system includes a discharging motor 37 installed on the base frame 1 and two pinch rollers 38 installed on the base frame 1. The output shaft end of the discharging motor 37 is in transmission connection with a fourth synchronous toothed belt, and both shaping rollers 6 are in transmission connection with the fourth synchronous toothed belt. Two pinch rollers 39 are rotatably installed on each pinch roller 38, and a gap for clamping and conveying the aluminum strip 3 is fixedly arranged between the two pinch rollers 39. Linkage gears are installed on both pinch rollers 39, and the two linkage gears are in transmission connection. Multiple pinch rollers 39 are linked by a fifth synchronous toothed belt, and one pinch roller 39 is in transmission connection with the fourth synchronous toothed belt.

[0084] When the uncoiling motor works, the servo motor 17 works synchronously. Its output shaft end drives the two shaping rollers 6 to rotate through the fourth synchronous toothed belt, and also drives one of the pinch rollers 39 to rotate. This pinch roller 39 drives other pinch rollers 39 to rotate through the fifth synchronous toothed belt. The linkage gears on the pinch rollers 39 are in transmission with each other, ensuring the synchronism of the rotation of the pinch rollers 39. The gap between the two pinch rollers 39 clamps and conveys the aluminum strip 3, and smoothly sends the finished aluminum strip 3 out of the device. This clamping and conveying method can ensure that the aluminum strip 3 will not shift and slack during the discharging process, ensuring the stable quality of the finished aluminum strip 3;

[0085] The working principle and usage process of the present invention:

[0086] When the aluminum coil edge finishing mechanical device of the present invention is working, the uncoiling motor drives the uncoiling roller 2 to rotate and release the aluminum strip 3. After passing through the guiding roller 15, the aluminum strip 3 is attached to the tensioning roller 32. The T-shaped guide rod 30 on the tensioning frame 29 of the tensioning system slides on the base frame 1, and the tensioning spring 31 elastically tensions the aluminum strip 3 by the tensioning roller 32, avoiding the slack and wrinkles of the aluminum strip 3 and providing a stable basis for subsequent processes. The servo motor 17 is started, and the first key shaft 18 at the output shaft end rotates, driving the first hollow shaft 21 to rotate. The large angular sector gear 24 and the small angular sector gear 25 rotate accordingly. Due to the existence of the non-transmission section, they periodically engage and disengage with the differential gear 27 on the second hollow shaft 22, driving the second hollow shaft 22 to rotate, and further causing the longitudinal screw 23 to rotate, driving the trimming frame 5 to reciprocate along the axis direction of the uncoiling roller 2;

[0087] At the same time, the second key shaft 19 drives the vertical screw 20 to rotate through the second synchronous toothed belt, causing the vertical vibration frame 4 to reciprocate in the vertical direction. The steering torsion springs 26 at the rotating joints of the vertical screw 20 with the base frame 1 and the longitudinal screw 23 with the vertical vibration frame 4 affect the displacement stroke and frequency, making it cycle and change. When the aluminum strip 3 passes through the shaping roller 6, the electric heating rod inside the shaping roller 6 and the electric heating block 16 inside the trimming frame 5 heat up to 450 °C to adjust the material properties of the aluminum strip 3. The shaping roller 6 made of stainless steel and with a length 1.4 times the width of the aluminum strip 3 shapes the entire width direction of the aluminum strip 3, eliminating minor deformations and unevenness and providing a better basis for turning and grinding;

[0088] The power system drives the reversing shaft 8 to rotate, drives the longitudinal screw 23 to rotate through the belt connection section 35 and the elastic tensioning transmission belt 36. The longitudinal screw 23 drives the grinding roller 12 to rotate through the third hollow shaft 34 and the second bevel gear. The grinding roller 12 drives the turning roller 11 to rotate through the first synchronous toothed belt. The turning tool 10 on the turning table 9 turns the edge of the aluminum strip 3, and the turning roller 11 finely processes the turned surface. The steel wire brush hairs on the grinding roller 12 polish the surface, making the edge of the aluminum strip 3 smoother. The waste storage drawer 14 collects the waste generated by turning and grinding;

[0089] Finally, the output shaft end of the servo motor 17 drives two shaping rollers 6 to rotate through the fourth synchronous toothed belt, and at the same time drives a pinch roller 39 to rotate. The pinch roller 39 drives other pinch rollers 39 to rotate through the fifth synchronous toothed belt. The linkage gears on the pinch rollers 39 ensure the rotational synchronism. The gap between the two pinch rollers 39 clamps and conveys the aluminum strip 3, and smoothly sends out the finished aluminum strip 3 from the device.
