Description

Technical Field

[0001] This invention relates to the field of aluminum coil processing technology, and in particular to a cutting device for aluminum coil manufacturing. Background Technology

[0002] An edge trimming device for aluminum coil manufacturing is a device used to straighten the edges of aluminum coils to remove burrs.

[0003] Aluminum coils, with their advantages of being lightweight, corrosion-resistant, highly malleable, and having an excellent appearance, are widely used in building curtain wall decoration, household appliance housings, lightweight automotive parts, food packaging substrates, and photovoltaic auxiliary profiles. In the large-scale production process of aluminum coils, edge trimming is a core finishing step, mainly used to remove irregular burrs from the edges of the aluminum coils and correct dimensional deviations. Existing devices of this type are prone to producing burrs when cutting aluminum. For example, an electrically controlled edge trimming device for aluminum coil manufacturing disclosed in Chinese Patent Publication No. CN202110355465 uses a cutter to remove the burrs from the aluminum material. However, in actual use, the surface of the aluminum material usually has an oxide film. During cutting, the oxide film cracks and pulls on the surrounding aluminum material, causing edge burrs, cracks, and other phenomena, thus producing burrs on the cut. Therefore, this application proposes an edge trimming device for aluminum coil manufacturing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an edge-cutting device for aluminum coil manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting device for aluminum coil manufacturing includes a scraping assembly, a heat dissipation assembly, and a collection assembly. The scraping assembly includes a device housing, a scraping box, a connecting pipe, a first liquid storage box, a first pump, and a second mounting plate.

[0007] The scraping box is fixedly connected to the side wall of the device housing. The scraping box is hollow inside. There are two scraping boxes, and the scraping boxes are fixedly connected to the side wall of the scraping box.

[0008] One end of the connecting pipe is connected to the internal space of one of the scraping boxes, and the other end of the connecting pipe is connected to the No. 1 pump. The No. 1 pump is fixedly connected to the upper surface of the No. 1 liquid storage box, and the No. 1 liquid storage box is fixedly connected to the upper surface of the No. 2 mounting plate.

[0009] Preferably, the heat dissipation assembly includes a liquid storage box shell, a second pump, a second liquid storage box, a microporous plate, and an inlet pipe;

[0011] Preferably, the collection assembly includes a squeezing cylinder, a collection box, a trimming roller, a rack, a gear, a cutting cylinder, a mounting plate, a cutting blade, a squeezing plate, and a blocking plate;

[0012] The extrusion cylinder is fixedly connected to the inner wall of the device housing, the collection box is fixedly connected to the inner wall of the device housing, the mounting plate is fixedly connected to the inner wall of the device housing, and the front end of the output rod of the extrusion cylinder is fixedly connected to the extrusion plate.

[0013] Preferably, the extrusion plate is slidably and sealed to the collection box, the cutting roller is rotatably connected to the mounting plate, and the cutting cylinder is fixedly connected to the side wall of the mounting plate.

[0014] Preferably, the gear is rotatably connected to the mounting plate, the rack is slidably connected to the mounting plate, one of the racks is fixedly connected to the output rod of the cutting cylinder, the cutting blade is fixedly connected to the rack, and the blocking plate is slidably connected to the collection box.

[0016] Preferably, a splash-proof housing is fixedly connected between the side walls of the device housing, the No. 1 motor is fixedly connected to the outer side wall of the device housing, and a rotating shaft is placed at the front end of the device housing.

[0017] Preferably, limit plates are fixedly connected to both ends of the rotating shaft, a cutting motor is installed on the outer wall of the device housing, and a conveying roller is rotatably connected between the two device housings.

[0019] The present invention has the following beneficial effects:

[0020] 1. By setting up a scraping component, when this device is in use, the aluminum oxide on the surface of the aluminum material will be scraped off first and then cut. At the same time, the cutting fluid will cover the scraped part to isolate it from the air, thereby preventing the regeneration of aluminum oxide and avoiding the problem of burrs on the cut.

[0021] 2. By setting up heat dissipation components, this device avoids the problem that when aluminum is heated and softens rapidly during cutting, the aluminum oxide film on the surface remains hard and brittle, causing the softened aluminum material to be unable to be separated and sheared normally, and to be continuously stuck and accumulated at the cutting edge, eventually compacting and solidifying to form aluminum nodules.

[0022] 3. By setting up a collection component, the device can collect the cut aluminum strips during aluminum cutting, and after collecting a certain amount, it can also compress and pack them into an aluminum block, which facilitates subsequent processing. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1:

[0037] A cutting device for aluminum coil manufacturing includes a scraping assembly, a heat dissipation assembly, and a collection assembly. The scraping assembly includes a device housing 1, a scraping box 26, a connecting pipe 25, a first liquid storage box 23, a first pump 24, and a second mounting plate 30.

[0038] The scraping box 26 is fixedly connected to the side wall of the device housing 1. The scraping box 26 is hollow inside, and there are two scraping boxes 26. One end of the connecting pipe 25 is connected to the internal space of one of the scraping boxes 26, and the other end of the connecting pipe 25 is connected to the first pump 24. The first pump 24 is fixedly connected to the upper surface of the first liquid storage box 23, and the first liquid storage box 23 is fixedly connected to the upper surface of the second mounting plate 30.

[0039] When using the scraping assembly, refer to... Figure 9 There are two scraping boxes 26, and their lower surfaces are in contact with the upper and lower surfaces of the aluminum material and are slightly pressed into the surface of the aluminum material. During cutting, motor 7 will run, driving the rotating shaft 8 to rotate, thereby winding the cut aluminum material. The rotating shaft 8 is placed at the front end of the device housing 1, and the limiting plates 9 at both ends of the rotating shaft 8 will restrict the axial position of the rotating shaft 8 to prevent it from moving axially when winding the aluminum material.

[0040] One end of the rotating shaft 8 is slidably connected to a limit pin 35, and the other end of the limit pin 35 is magnetically connected to the first motor 7 to form a limit, thereby allowing the power of the first motor 7 to be transmitted to the rotating shaft 8. Limit plates 9 are fixedly connected to both ends of the rotating shaft 8.

[0041] A cutting motor 10 is installed on the outer wall of the device housing 1, and a conveying roller 11 is rotatably connected between the two device housings 1. A transport motor 13 is fixedly connected to the second mounting plate 30, a cutting blade 22 is fixedly connected to the output shaft of the cutting motor 10, a baffle plate 29 is fixedly connected to the splashproof housing 6, and a limit pin 35 is slidably connected to one end of the rotating shaft 8.

[0042] It should be noted that this device is mainly intended for use in continuous production lines for industrial aluminum coils. It can stably adapt to the edge cutting operations of conventional cold-rolled aluminum strips, decorative aluminum coils, packaging aluminum foils, and curtain wall aluminum substrates with aluminum coil thicknesses ranging from 0.3mm to 2.5mm.

[0043] The effective scraping width of the scraping box 26 is designed to be 4mm wider than the cutting edge width, so it can completely cover the edge area of ​​the aluminum coil to be cut, ensuring that there is no oxide film residue at the cutting position. It can stably complete the removal of surface oxide film at the normal conveyor speed of 20m / min to 100m / min on the production line.

[0044] As the aluminum material is wound, its surface scrapes against the area where the scraper box 26 contacts the aluminum surface. At this time, the protrusions on the lower surface of the scraper box 26 scrape away the oxide layer on the aluminum surface as the aluminum material moves, thus removing the oxide film. After the oxide film is removed, pump 24 can be activated. Once activated, pump 24 injects cutting fluid from the first reservoir 23 into the scraper box 26. It should be noted that this process is intermittent. Pump 24 will only be activated after the cutting fluid in the scraper box 26 has been depleted.

[0045] refer to Figure 9 The scraper box 26 has an internal notch located near the cutting blade 22. Since the cutting fluid is contained within the scraper box 26, when the aluminum material is pulled out from below, the scraped area on either the upper or lower surface of the aluminum material is coated with the cutting fluid. This isolates the aluminum from external air, preventing the aluminum from contacting oxygen in the external environment and forming aluminum oxide. Because this notch is located on one side of the cutting blade 22, the aluminum material is cut directly after moving a short distance after scraping, thus removing aluminum oxide from the surface of the aluminum and preventing its regeneration.

[0046] Example 2:

[0047] The heat dissipation assembly includes a liquid storage box shell 12, a second pump 31, a second liquid storage box 32, a microporous plate 33, and an inlet pipe 28. The second liquid storage box 32 is fixedly connected to the inside of the liquid storage box shell 12, the second pump 31 is fixedly connected to the upper surface of the second liquid storage box 32, the microporous plate 33 is fixedly connected to the side wall of the second liquid storage box 32, and the inlet pipe 28 is fixedly connected to the inlet of the second pump 31.

[0048] The extrusion plate 21 is slidably and sealed to the collection box 15; the cutting roller 16 is rotatably connected to the mounting plate 35; and the cutting cylinder 20 is fixedly connected to the side wall of the mounting plate 35. The gear 18 is rotatably connected to the mounting plate 35; the rack 17 is slidably connected to the mounting plate 35; one of the racks 17 is fixedly connected to the output rod of the cutting cylinder 20; the cutting disc 22 is fixedly connected to the rack 17; and the blocking plate 34 is slidably connected to the collection box 15.

[0049] It should be noted that the atomized cooling area of ​​the heat dissipation component is no less than 22mm wide, completely covering the cutting area, friction area, and heat-affected zone where the cutting blade contacts the aluminum material. At the conveyor speed in Example 1, the temperature of the cutting area can be stably controlled below 55℃, preventing the aluminum material from softening and sticking due to high temperature, and avoiding accelerated edge wear due to oxide film hardening. This effectively inhibits the formation of aluminum nodules, extends the continuous working time of the blade, and meets the heat dissipation requirements of long-term, high-load industrial edge cutting production.

[0050] The heat dissipation component is used to dissipate heat from the saw blade during cutting. When cutting, the two cutting blades 22 rub against the aluminum material, which generates high temperatures and heats the aluminum material. At this time, the second pump 31 can be activated. After the second pump 31 is activated, the cutting fluid in the second liquid storage box 32 will be sprayed out from its interior and enter the liquid storage box shell 12. Since the liquid storage box shell 12 is closed, only the microporous plate 33 connects its interior with the external space.

[0051] Therefore, the cutting fluid inside passes through the microporous plate 33 and is then atomized and sprayed into the cutting disc 22. Subsequently, due to the centrifugal force generated by the rotation of the cutting disc 22, the inner wall of the splash guard 6 flows down with it. The baffle plate 29 is fixedly connected to the upper splash guard 6.

[0052] Furthermore, the length of the splash guard 6 does not completely cover the upper splash guard 6, so coolant flows from both ends of the baffle plate 29 into the lower splash guard 6. Since the inlet pipe 28 is connected to the inlet end of the second pump 31, when the second pump 31 is running, it draws the coolant from the lower splash guard 6 into the second reservoir 32, and then atomizes it from the microporous plate 33 to create circulation and dissipate heat from the cutting blade 22.

[0053] Example 3:

[0054] The collection assembly includes a squeezing cylinder 14, a collection box 15, a trimming roller 16, a rack 17, a gear 18, a cutting cylinder 20, a mounting plate 35, a cutting disc 22, a squeezing plate 21, and a blocking plate 34. The squeezing cylinder 14 is fixedly connected to the inner wall of the device housing 1, the collection box 15 is fixedly connected to the inner wall of the device housing 1, the mounting plate 35 is fixedly connected to the inner wall of the device housing 1, and the front end of the output rod of the squeezing cylinder 14 is fixedly connected to the squeezing plate 21.

[0055] A rotating plate 2 is threaded onto the outer wall of the device housing 1. A placement cylinder 4 is fixedly connected between two device housings 1. A protective shell 5 is fixedly connected to the side wall of the device housing 1. A splash-proof shell 6 is fixedly connected between the side walls of the device housings 1. A first motor 7 is fixedly connected to the outer wall of the device housing 1. A rotating shaft 8 is placed at the front end of the device housing 1.

[0056] It should be noted that the cutting length of the edge strips is uniformly controlled between 60mm and 90mm to prevent excessively long edge strips from bending, jamming, or entanglement with the cutting rollers during conveying. The cut edge strips fall precisely into the collection box 15 via guide grooves, where they naturally accumulate in layers under gravity. The bottom of the collection box is designed with an inclined structure to guide the edge strips to automatically slide towards the extrusion area. This avoids material accumulation in corners and dead zones. The collection box 15 can hold a maximum of approximately 8kg of waste edge strips at a time.

[0057] When the waste edges accumulate to the set capacity, the extrusion cylinder 14 is activated to compact the loose edge strips with a working pressure of 0.5MPa to 0.8MPa, ultimately forming a flat aluminum block with an irregular outer contour. Therefore, it can be directly stacked and stored without additional packaging or bundling.

[0058] When the collecting component is working, it will cut the shavings into pieces and cause them to fall into the collecting box 15. During operation, the shavings will move towards the first motor 7 under the operation of the first motor 7.

[0059] The cut edge is pressed by the cutting roller 16 and continuously moves towards the extrusion cylinder 14. When it moves a certain distance, the cutting cylinder 20 can be activated. The cutting cylinder 20 is activated intermittently, so that one of the racks 17 moves up and down. Since the racks 17 and gears 18 mesh with each other, and each rack 17 is fixedly connected to a cutting blade 22, when one rack 17 moves, the other rack 17 will also move, so that the two cutting blades 22 move in opposite directions, thereby completing the cutting of the edge strip.

[0060] The trimmed strips fall into the collection box 15. When the amount of strips accumulates to a certain level, the extrusion cylinder 14 can be activated. The output rod of the extrusion cylinder 14 will extrude the strips, and during extrusion, it will touch the blocking plate 34. The blocking plate 34 will be pushed out, thereby opening the gap that it was blocking. The extruded strip block will then fall out of the gap, facilitating subsequent processing.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
