Description

Technical Field

[0001] This invention relates to the field of grinding and polishing technology, specifically to a grinding and polishing production line for refined steel. Background Technology

[0002] With the continuous development of national construction and the gradual improvement of people's aesthetic awareness and personalized aesthetic needs, architectural glass curtain walls have gradually evolved from their original simple enclosure function to a more aesthetically pleasing, safe, and practical design. The original aluminum alloy keel for glass curtain walls has been questioned by designers due to its lower fire resistance. Furthermore, with the increasing number of high-rise buildings and large venues, and designers and construction units constantly pursuing grand designs, the strength and economy of ultra-high aluminum alloy keels have become increasingly disadvantageous due to their increasing weight and thickness. Meanwhile, with the continuous maturation of technologies such as laser cutting, automatic welding, and hot-rolled right-angle square and round tube drawing, the processing cost of steel curtain wall keels is constantly decreasing. This has allowed precision-machined steel pipe keels to gradually reach or even surpass aluminum alloy curtain wall keels in appearance and performance. Moreover, due to the advantages of steel in terms of strength, fire resistance, and price, this trend of using precision steel to replace aluminum alloy keels will become increasingly prevalent. Therefore, continuously researching, developing, and improving the manufacturing process of precision steel keels has become an important research direction for the prefabricated curtain wall keel manufacturing industry in the near future.

[0003] In the refining of steel, strip steel plates need to be welded. After welding, the plates must be ground and polished to achieve a smoothness and gloss similar to aluminum alloys and stainless steel. Currently, the welding process uses continuous welding, resulting in long sections of material requiring grinding and polishing. Grinding multiple weld joints is inefficient, and manual grinding yields inconsistent quality, making it difficult to meet customer requirements. Using belt sanders also leads to significant waste of materials and manpower. Furthermore, when transporting steel via ordinary conveyor belts or chains, slippage occurs due to the contact between the grinding machinery and the steel surface, compromising the accuracy of grinding and polishing quality – a major challenge in this industry. Therefore, a solution to these problems is urgently needed. Summary of the Invention

[0004] This invention proposes a refined steel grinding and polishing production line, which solves the problem in related technologies where multiple welds cannot be ground simultaneously during continuous grinding due to the long length of the welded refined steel. It also provides a solution for online polishing in a single operation after grinding, and addresses the issue of slippage between the refined steel and the conveyor chain during transport. This production line has the function of simultaneously grinding and polishing multiple welds. Multiple sets of electric and manual lead screw slide devices and elastic bodies are used to control the wear of the grinding wheel and compensate for the grinding force. The grinding wheel angle can be adjusted according to the different shapes of the refined steel and the position of the welds to be ground. Furthermore, a variable speed permanent magnet spindle motor is used to explore beneficial improvements in the grinding wheel's rotation speed and grinding efficiency.

[0013] A connecting plate is disposed on the first connecting platform, and the feed end of the connecting plate is flush with the top of the first magnet.

[0014] As a further technical solution, the limiting component also includes,

[0015] The second connecting table is mounted on the machine body and is located at the feed end of the conveyor chain.

[0016] A first movable seat, and several first movable seats are respectively slidably disposed on the first connecting platform and the second connecting platform.

[0017] A plurality of second movable seats are slidably disposed on the first connecting platform and the second connecting platform, with adjacent first and second movable seats located on opposite sides of the conveying direction, and the adjacent first and second movable seats moving closer to or further away from each other.

[0018] A plurality of limiting wheels are respectively rotatably disposed on the first connecting platform and the second connecting platform, and the limiting wheels move with the first connecting platform or the second connecting platform.

[0019] As a further technical solution, both the first movable seat and the second movable seat have a first threaded hole, and the limiting component also includes...

[0020] A first drive rod is rotatably mounted on a first movable seat and a second movable seat. The first drive rod has a first threaded portion. The first threaded holes of the first movable seat and the second movable seat are threadedly engaged with the first threaded portion. The rotation of the first drive rod is used to drive the first movable seat and the second movable seat to move.

[0021] As a further technical solution, it also includes,

[0022] A second magnet is disposed on the machine body and located at the feed end of the conveyor chain. The projection area of ​​the second magnet onto the drive sprocket is the discharge area. The working end of the second magnet corresponds to the first magnet.

[0023] The receiving trough has its inlet end connected to the dropping area, and the receiving trough forms an angle with the vertical direction, and the receiving trough is offset away from the drive sprocket.

[0024] As a further technical solution, the grinding and polishing assembly includes,

[0025] A first adjusting seat is slidably disposed on the machine body, and the first adjusting seat can move along the conveying direction or the opposite direction.

[0026] The second adjusting seat is slidably disposed on the first adjusting seat in a vertical direction.

[0027] A flipping component, hinged to the pivot point, rotates around the pivot point.

[0028] A grinding wheel is rotatably mounted and follows the flipping component.

[0029] As a further technical solution, the grinding and polishing assembly also includes,

[0030] A guide member is slidably disposed on the flipping member, and the guide member is slidably moved toward or away from the workpiece to be processed.

[0031] A first elastic element, one end of which is connected to the guide element and the other end of which is connected to the flipping element, is used to cause the guide element to slide along the flipping element.

[0034] The working principle and beneficial effects of this invention are as follows:

[0035] In current technologies, due to the numerous and long weld beads in refined steel welding, it is impossible to grind and polish multiple weld beads simultaneously during continuous grinding. Furthermore, during the grinding and conveying process, slippage may occur between the refined steel and the conveyor chain due to the high grinding resistance. To address these technical problems, this invention proposes a refined steel grinding and polishing production line.

[0036] This production line is capable of simultaneously grinding and polishing multiple weld joints. It employs multiple sets of electric and manual lead screw slide devices and elastic bodies to control grinding wheel wear and grinding force compensation. The grinding wheel angle can also be adjusted according to the different shapes of the refined steel and the position of the weld bead being ground. Furthermore, a variable speed permanent magnet spindle motor is being used to explore ways to improve the grinding wheel's rotation speed and grinding efficiency.

[0037] The production line's conveying assembly is equipped with several first magnets, which fix the conveying assembly and the workpiece in place. Permanent magnets are preferred because they are less expensive and require only frictional force during transport, rather than a large traction force. Chain and sprocket drives are preferred for the conveying assembly because chains facilitate the installation of the first magnets.

[0038] During operation, after the refined steel is welded, it enters the conveying assembly. The primary magnet attracts the refined steel, converting this attraction into friction. The conveying assembly then moves the refined steel, thus achieving stable transport.

[0039] The beneficial effect is that by installing a first magnet on the conveying assembly, the friction between the conveying assembly and the steel can be increased, thereby enabling the conveying of the steel and preventing slippage. Attached Figure Description

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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.

[0047] like Figures 1-4 As shown, this embodiment proposes a refined steel grinding and polishing production line, including a machine body 1 and a conveying assembly and a grinding and polishing assembly disposed on the machine body 1; it also includes,

[0048] A first magnet 2, there are several first magnets 2, and several first magnets 2 are evenly arranged on the surface of the conveying assembly. The first magnets 2 move along the conveying direction with the conveying assembly.

[0049] In this embodiment, to solve the aforementioned technical problems, a precision steel grinding and polishing production line is proposed. The production line's conveying assembly is equipped with several first magnets 2, which fix the conveying assembly and the workpiece together. The first magnets 2 are preferably permanent magnets, as they are less expensive and require only frictional force during transport, rather than a large traction force. The conveying assembly is preferably driven by chains and sprockets, as chains facilitate the installation of the first magnets 2.

[0050] During operation, after the refined steel is welded, it enters the conveying assembly. The first magnet 2 exerts an attractive force on the refined steel, converting this force into friction. The conveying assembly then moves the steel, thus achieving stable conveying.

[0051] By installing the first magnet 2 on the conveying assembly, the friction between the conveying assembly and the steel can be increased, thereby enabling the conveying of the steel and preventing slippage.

[0052] Furthermore, the conveying assembly includes,

[0053] A drive sprocket 3 is rotatably mounted on the machine body 1, with two drive sprockets 3 located at the feed end and discharge end of the conveying assembly.

[0054] A conveyor chain 4 is sleeved on two drive sprockets 3, and a plurality of first magnets 2 are evenly arranged on the surface of the conveyor chain 4.

[0055] In this embodiment, the conveying assembly adopts the form of a conveying chain 4 and a drive sprocket 3, which facilitates the installation of the first magnet 2 on the drive sprocket 3 or the conveying chain 4 and makes it easy to replace.

[0056] Furthermore, it also includes a limiting component, the limiting component comprising,

[0057] The first connecting platform 5 is mounted on the machine body 1 and is located at the discharge end of the conveyor chain 4.

[0058] A connecting plate 6 is disposed on the first connecting platform 5, and the feed end of the connecting plate 6 is flush with the top of the first magnet 2.

[0059] In this implementation, the refined steel is conveyed by the attraction of the first magnet 2. When the refined steel detaches from the conveyor chain 4, if the running direction of the conveyor chain is not limited, the conveyor chain 4 will continue to follow the steel. This will risk the chain detaching from the sprocket and thus not running smoothly towards the sprocket. Therefore, a connecting plate 6 is required. When the refined steel is about to detach from the conveyor chain 4, the connecting plate 6 will extend between the conveyor chain 4 and the refined steel, thereby separating it from the connecting plate 6, so that the material can continue to be sent out from the first connecting table 5.

[0060] Furthermore, the limiting component also includes,

[0061] The second connecting platform 7 is mounted on the machine body 1 and is located at the feed end of the conveyor chain 4.

[0062] A plurality of first movable seats 8 are respectively slidably disposed on the first connecting platform 5 and the second connecting platform 7.

[0063] The second movable seat 9, and several second movable seats 9 are respectively slidably disposed on the first connecting platform 5 and the second connecting platform 7. Adjacent first movable seats 8 and second movable seats 9 are located on opposite sides of the conveying direction, and adjacent first movable seats 8 and second movable seats 9 move closer to or further away from each other.

[0064] A plurality of limit wheels 10 are respectively rotatably disposed on the first connecting platform 5 and the second connecting platform 7, and the limit wheels 10 move with the first connecting platform 5 or the second connecting platform 7.

[0065] In this embodiment, the first connecting platform 5 and the second connecting platform 7 are located at the feed end and the discharge end of the conveying chain 4, respectively. A first movable seat 8 is provided on the first connecting platform 5 and the second connecting platform 7. The first movable seat 8 is also equipped with a limit wheel 10. The limit wheel 10 will limit the steel from both sides to prevent horizontal displacement, which would affect the processing accuracy. The material is positioned from both ends of the conveying chain 4 to prevent the steel from shifting during the conveying process.

[0066] Furthermore, both the first movable seat 8 and the second movable seat 9 have a first threaded hole 25, and the limiting component also includes,

[0067] A first drive rod 11 is rotatably mounted on the first movable seat 8 and the second movable seat 9. The first drive rod 11 has a first threaded portion 24. The first threaded holes 25 of the first movable seat 8 and the second movable seat 9 are threadedly engaged with the first threaded portion 24. The rotation of the first drive rod 11 is used to drive the first movable seat 8 and the second movable seat 9 to move.

[0068] In this embodiment, the first drive rod 11 is threadedly engaged with the first threaded hole 25 of the first movable seat 8 and the second movable seat 9 through the first threaded part 24, so that the position of the first movable seat 8 and the second movable seat 9 can be adjusted by rotating the first drive rod 11, making the processing more convenient.

[0069] Furthermore, it also includes,

[0070] A second magnet 12 is mounted on the machine body 1 and located at the feed end of the conveyor chain 4. The projection area of ​​the second magnet 12 onto the drive sprocket 3 is the discharge area. The working end of the second magnet 12 corresponds to the first magnet 2.

[0071] The receiving trough 13 has its inlet end connected to the dropping area. The receiving trough 13 forms an angle with the vertical direction and is offset away from the drive sprocket 3.

[0072] In this embodiment, because many debris, mostly metal powder, will be generated during the grinding and polishing process, it may be adsorbed onto the first magnet 2. If these debris are adsorbed onto the surface of the first magnet 2, it will make the material uneven during transportation and affect the processing accuracy. Therefore, the second magnet 12 is set to clean the debris adsorbed on the first magnet 2 before the first magnet 2 starts working. The second magnet 12 will release an opposite magnetic field, thereby losing the magnetic field in the material drop area, so that the material falls off the first magnet 2 due to gravity. The receiving trough 13 is used to receive the debris falling from the material drop area and collect it to prevent it from affecting the first magnet 2 again. The second magnet 12 can be an electromagnet because the number of second magnets 12 is small and the magnetic force can be adjusted to adapt to the magnetic field generated by different first magnets 2.

[0073] Furthermore, the grinding and polishing assembly includes,

[0074] A first adjusting seat 14 is slidably disposed on the machine body 1, and the first adjusting seat 14 can move along the conveying direction or the opposite direction.

[0075] The second adjusting seat 15 is vertically slidably disposed on the first adjusting seat 14.

[0076] A flipping component 16 is hinged to the second adjusting seat 15, and the flipping component 16 rotates around the hinge point.

[0077] Grinding wheel 17 is rotatably mounted on the flipping member 16 and rotates with the flipping member 16.

[0078] In this embodiment, the second adjusting seat 15 is moved to adjust the vertical position, and the flipping part 16 can keep the grinding wheel 17 in contact with the steel. So even if the grinding wheel 17 is worn, it will be flipped by the flipping part 16, so that the steel can be continuously ground and polished, thereby improving the polishing effect.

[0079] Furthermore, the grinding and polishing assembly also includes,

[0080] Guide member 18, slidably disposed on the flipping member 16, the guide member 18 is slidably used to move closer to or further away from the workpiece to be processed.

[0081] A first elastic element 19 is connected at one end to the guide element 18 and at the other end to the flipping element 16. The first elastic element 19 is used to cause the guide element 18 to slide along the flipping element 16.

[0082] In this embodiment, the guide member 18 is used to adjust the position of the grinding wheel 17. The guide member 18 can be a steel column roller. One end of the guide member 18 will contact the steel surface to reduce the friction during movement. The first elastic member 19 allows the guide member 18 to maintain contact with the steel surface.

[0083] Furthermore, the grinding and polishing assembly also includes,

[0084] The second elastic element 20 has one end connected to the second adjusting seat 15 and the other end connected to the flipping element 16. The second elastic element 20 is used to cause the flipping element 16 to rotate along the hinge point.

[0085] In this embodiment, the second elastic element 20 is used to enable the flipping element 16 to rotate continuously toward the steel. The elastic coefficient of the second elastic element 20 is greater than that of the first elastic element 19. Therefore, the second elastic element 20 will cause the flipping element 16 to rotate. The flipping element 16 rotates and acts on the guide element 18 to squeeze the first elastic element 19, so that the grinding wheel 17 can contact the steel surface and grind and polish the steel surface.

[0086] Furthermore, the grinding and polishing assembly has two or more sets, and each set of the grinding and polishing assembly has two first adjustment seats 14, two second adjustment seats 15, two flipping parts 16 and two grinding wheels 17.

[0087] In this embodiment, two sets of grinding and polishing components can polish and grind the steel from both sides. Each set of grinding and polishing components has two first adjustment seats 14, two second adjustment seats 15, a second flipping part 16, and two grinding wheels 17, which can perform secondary grinding on the steel, thereby improving the grinding effect.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
