Description

Technical Field

[0001] This invention relates to the field of metal plate processing, and more specifically, to an edge-cutting and grinding device for aluminum plate production and processing. Background Technology

[0002] Aluminum sheet refers to rectangular plates rolled from aluminum ingots. It is categorized into pure aluminum sheets, alloy aluminum sheets, thin aluminum sheets, medium-thick aluminum sheets, and patterned aluminum sheets. Aluminum materials with a thickness of 0.2mm to 500mm, a width of 200mm or more, and a length of 16m or less are referred to as aluminum sheets or aluminum plates. Materials with a thickness of less than 0.2mm are considered aluminum materials, and those with a width of 200mm or less are considered strips or bars. Aluminum sheets are lightweight, corrosion-resistant, and easy to process, and are widely used in construction, home decoration, transportation, aerospace, and other fields.

[0003] Edge trimming and grinding of aluminum sheets is a crucial process in aluminum processing, involving the dual objectives of dimensional accuracy control and surface quality optimization. Edge trimming is mainly used to remove excess edge material generated after aluminum sheet rolling or cutting, ensuring that the width dimensions meet requirements and eliminating wavy or cracked edges caused by the rolling process. For example, after trimming, aluminum coils have more regular edges and a more uniform distribution of tensile strength, making them suitable for precision machining. Grinding aims to improve the surface quality of aluminum sheet edges after trimming or other processing, removing burrs, oxide layers, or sharp edges remaining from the trimming, resulting in smooth and flat edges. In the existing technology, due to the low hardness and high plasticity of aluminum plates, continuous chips rather than broken chips are easily generated during processing, especially during roughing or large cutting. The long strips of chips gradually accumulate and fall, which can cause the aluminum plate cut to tear, affecting not only the processing quality of the aluminum plate, but also increasing the downtime for processing. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide an edge trimming and grinding device for aluminum plate production and processing.

[0005] To solve the above problems, the present invention adopts the following technical solution, which can guide the long strip of material through the guide groove during the cutting process of the cutting part on the aluminum plate, so as to avoid the long strip of material from being pulled at the connection between the aluminum plate and the long strip of material due to its own weight when a large number of long strips of material are accumulated.

A crushing box is fixedly connected to the front side of the cutting part. A guide frame is fixedly connected to the left side of the crushing box. A guide groove is provided through the back side of the guide frame.

[0007] Furthermore, a grinding component is slidably connected to the upper left side of the machine body, the rotating seat is located between the grinding component and the cutting component, and the extrusion plate moves downward and makes extrusion contact with the aluminum plate on the upper side of the rotating seat.

[0008] Furthermore, the lower inner side of the guide groove is at the same horizontal level as the upper side of the rotating seat, the lower inner side of the guide frame is inclined from left to right, and the guide frame is connected to the crushing box.

[0009] Furthermore, the back side of the guide frame is provided with a pressing component, which includes a positioning plate fixedly connected to the left side of the cutting piece.

[0010] Furthermore, the upper and lower sides inside the positioning plate are on the same horizontal line as the upper and lower sides inside the guide groove, the lower side inside the positioning plate is on the same horizontal line as the upper side of the rotating seat, and the upper and lower sides inside the positioning plate are connected by first ball bearings through rolling. The side of the positioning plate away from the guide frame is chamfered. The positioning plate is L-shaped, and the guide groove is L-shaped.

[0011] Furthermore, a support assembly is provided on the upper side of the body, the support assembly including fixed columns arranged in a ring array and fixedly connected to the upper side of the body.

[0012] Furthermore, a groove is provided on the upper side of the inside of the fixing column, and a second ball is tumblingly connected inside the groove. Multiple fixing columns surround the outside of the rotating seat, and the uppermost side of the second ball is at the same horizontal line as the upper side of the rotating seat.

[0013] Furthermore, a cooling component is provided on the left side of the cutting component, the cooling component including a storage box fixedly connected to the left side of the cutting component.

[0014] Furthermore, a conduit is fixedly connected to the upper side of the storage tank, a water-air mixing spray gun is fixedly connected to the left side of the storage tank, and a transfer box is fixedly connected to the left side of the storage tank. The transfer box surrounds the outside of the water-air mixing spray gun. Water outlets are arranged in a rectangular array on the upper side of the transfer box. The conduit is connected to the storage tank, and the other end of the conduit is connected to an external water supply pressure tank. The water outlets are opened at an angle, and the angles of the water outlets on the left and right sides are opposite.

[0015] Furthermore, a movable groove is provided on the upper left side of the transfer box, and a movable plate is slidably connected inside the movable groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention guides the long strip of material through the guide groove to prevent the long strip of material from falling. During the cutting process of the cutting part cutting the aluminum plate, the guide frame always guides the long strip of material cut by the cutting part through the guide groove and keeps the long strip of material moving horizontally. This avoids the long strip of material from pulling on the connection between the aluminum plate and the long strip of material due to its own weight when a large number of long strips of material accumulate, thereby reducing the probability of the aluminum plate being torn or damaged, and ensuring the processing quality of the aluminum plate.

[0017] (2) The present invention uses two first ball bearings to press the cut part of the aluminum plate. After the cutting part cuts the aluminum plate, the positioning plate guides the long strip of material. The two first ball bearings inside the positioning plate will press the connection between the aluminum plate and the long strip of material respectively, so as to reduce the tearing caused by the long strip of material after it sinks down, and further ensure the processing quality of the aluminum plate.

[0018] (3) The present invention supports the aluminum plate with a larger panel by setting the second ball bearing, while ensuring the smooth rotation of the aluminum plate. Since the aluminum plate with a larger area than the rotating seat is being cut and polished, the second ball bearing inside the fixed column can support the aluminum plate, and the second ball bearing inside the groove can ensure the smooth rotation of the aluminum plate, so that the aluminum plate can rotate in a horizontal state, avoiding the aluminum plate from falling and affecting the cutting and polishing effect.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 A cutting and grinding device for aluminum plate production and processing includes a machine body 1 and a cutting component 12 disposed on the upper right side of the machine body 1. A rotating seat 13 is rotatably connected to the upper center of the machine body 1, and a material fixing component 2 is provided on the upper side of the machine body 1. The material setting component 2 includes a cylinder 21 fixedly connected to the upper side of the machine body 1. A movable seat 23 is fixedly connected to the telescopic end of the cylinder 21. Limiting rods 22 are fixedly connected to the left and right sides of the lower end of the movable seat 23. The limiting rods 22 are slidably connected to the upper side of the machine body 1. A motor 24 is provided on the upper side of the movable seat 23. An extrusion plate 25 is fixedly connected to the output end of the motor 24. A crushing box 26 is fixedly connected to the front side of the cutting part 12. A guide frame 27 is fixedly connected to the left side of the crushing box 26. A guide groove 271 is provided through the back side of the guide frame 27.

[0023] A grinding component 11 is slidably connected to the upper left side of the machine body 1. The rotating seat 13 is located between the grinding component 11 and the cutting component 12. After the extrusion plate 25 moves downward, it makes extrusion contact with the aluminum plate on the upper side of the rotating seat 13.

[0024] The lower inner side of the guide groove 271 is at the same horizontal level as the upper side of the rotating seat 13. The lower inner side of the guide frame 27 is inclined from left to right. The guide frame 27 is connected to the crushing box 26.

[0025] By adopting the above technical solution, after the aluminum plate is placed above the rotating seat 13, the cylinder 21 is started to pull the moving seat 23 downward until the extrusion plate 25 at the output end of the motor 24 contacts the top of the aluminum plate, so that the extrusion plate 25, together with the rotating seat 13, clamps the aluminum plate. Then, the motor 24 is started to drive the extrusion plate 25 to rotate, and the aluminum plate pressed by the extrusion plate 25 above the rotating seat 13 will begin to rotate. At the same time, the machine body 1 adjusts the position of the cutting piece 12 and controls the operation of the cutting piece 12, so that the cutting piece 12 cuts the edge of the aluminum plate it contacts until the aluminum plate is cut into the specified disc shape. Then, the machine body 1 adjusts the position of the grinding piece 11 and starts the operation of the grinding piece 11, so that the grinding piece 11 grinds the edge of the aluminum plate during the rotation process. During the process of the cutting piece 12 cutting the edge of the aluminum plate, when the cutting piece 12 approaches the aluminum plate, it will pass through the crushing box 26. The guide frame 27 moves together with the cutting piece 12, so that while the cutting piece 12 contacts the aluminum plate, the edge of part of the aluminum plate will insert into the guide groove 271. This allows the guide frame 27 to guide the cut strip-shaped material and keep it horizontal. Then, after the extrusion plate 25 drives the aluminum plate to rotate, the strip-shaped material will gradually slide from the guide groove 271 into the connection between the guide frame 27 and the crushing box 26, and finally enter the crushing box 26 for unified processing. During the cutting process of the cutting piece 12, the guide frame 27 always guides the strip-shaped material cut by the cutting piece 12 through the guide groove 271 and keeps the strip-shaped material moving horizontally. This avoids the strip-shaped material from pulling on the connection between the aluminum plate and the strip-shaped material due to its own weight when a large number of strip-shaped material accumulates, thereby reducing the probability of the aluminum plate tearing or being damaged, and ensuring the processing quality of the aluminum plate.

[0026] like Figures 4 to 6 As shown, a pressing assembly 28 is provided on the back side of the guide frame 27. The pressing assembly 28 includes a positioning plate 281 fixedly connected to the left side of the cutting piece 12.

[0027] The upper and lower sides of the positioning plate 281 are on the same horizontal line as the upper and lower sides of the guide groove 271. The lower side of the positioning plate 281 is on the same horizontal line as the upper side of the rotating seat 13. The upper and lower sides of the positioning plate 281 are connected by first ball bearings 282. The side of the positioning plate 281 away from the guide frame 27 is chamfered. The positioning plate 281 is "L" shaped and the guide groove 271 is "L" shaped.

[0028] By adopting the above technical solution, during the cutting process of the aluminum plate by the cutting component 12, the positioning plate 281 will surround the aluminum plate, and the cut strip-shaped material will also be between the two first rollers 282. As the aluminum plate continues to rotate, because the two first rollers 282 inside the positioning plate 281 are always at the point where the cutting component 12 is about to cut the aluminum plate, after the aluminum plate is cut, the two first rollers 282 will press the connection between the aluminum plate and the strip-shaped material. As the cutting component 12 cuts the aluminum plate, during the process of the positioning plate 281 guiding the strip-shaped material, the two first rollers 282 inside the positioning plate 281 will press the connection between the aluminum plate and the strip-shaped material respectively, so as to reduce the tearing caused by the strip-shaped material sinking to the connection between the aluminum plate and the strip-shaped material, and further ensure the processing quality of the aluminum plate.

[0029] like Figures 1 to 3 As shown, the upper side of the body 1 is provided with a support component 29, which includes fixed columns 291 arranged in a ring array and fixedly connected to the upper side of the body 1.

[0030] The upper side of the fixed post 291 has a groove 292, and the second ball 293 is rolled inside the groove 292. Multiple fixed posts 291 surround the outer side of the rotating seat 13, and the uppermost side of the second ball 293 is at the same horizontal line as the upper side of the rotating seat 13.

[0031] By adopting the above technical solution, when the extrusion plate 25 drives the aluminum plate to rotate on the upper side of the rotating seat 13, if the area of ​​the aluminum plate is larger than the rotating seat 13, the part of the aluminum plate that exceeds the rotating seat 13 can be placed above the fixed column 291 and supported by the second ball bearing 293. As the aluminum plate starts to rotate, the part of the aluminum plate that exceeds the rotating seat 13 will rotate on the upper side of the second ball bearing 293. During this process, the second ball bearing 293 rolls in the groove 292 on the upper side of the fixed column 291 under the drive of the aluminum plate. The aluminum plate supported by the second ball bearing 293 will always remain horizontal. Since the aluminum plate with an area larger than the rotating seat 13 is being trimmed and polished, the second ball bearing 293 on the upper side of the fixed column 291 can support the aluminum plate. The second ball bearing 293 in the groove 292 can ensure that the aluminum plate rotates smoothly, so that the aluminum plate can rotate in a horizontal state, avoiding the aluminum plate from falling and affecting the trimming and polishing effect.

[0032] like Figures 4 to 8 As shown, a cooling component 3 is provided on the left side of the cutting component 12. The cooling component 3 includes a storage box 31 fixedly connected to the left side of the cutting component 12.

[0033] A conduit 32 is fixedly connected to the upper side of the storage tank 31. A water-air mixing spray gun 33 is fixedly connected to the left side of the storage tank 31. A transfer box 34 is fixedly connected to the left side of the storage tank 31. The transfer box 34 surrounds the outside of the water-air mixing spray gun 33. Water outlets 35 are arranged in a rectangular array on the upper side of the interior of the transfer box 34. The conduit 32 is connected to the storage tank 31. The other end of the conduit 32 is connected to an external water supply pressure tank. The water outlets 35 are opened at an angle, and the angles of the water outlets 35 on the left and right sides are opposite.

[0034] A movable groove 36 is provided on the upper left side of the transfer box 34. A movable plate 37 is slidably connected inside the movable groove 36. The upper left side of the movable plate 37 is inclined. A striker 38 is fixedly connected to the lower center of the movable plate 37. A pressure sensor 39 is provided on the lower inside of the movable groove 36. After the bottom end of the striker 38 moves downward, it presses against the upper side of the pressure sensor 39. Two pressure springs 4 are fixedly connected between the lower side of the movable plate 37 and the lower inside of the movable groove 36. The back side of the guide frame 27 presses against the outer surface of the storage box 31.

[0035] By adopting the above technical solution, while the cutting component 12 is running, the external water supply pressure tank will send liquid into the storage tank 31. After the aluminum plate is placed above the rotating seat 13, the moving cutting component 12 will drive the transfer box 34 to move. When the cutting component 12 stops moving, the aluminum plate will cover the upper left side of the transfer box 34 and squeeze the moving plate 37. When the moving plate 37 retracts into the moving groove 36, the moving plate 37 will squeeze the pressure spring 4. When the impact pin 38 on the lower side of the moving plate 37 contacts the pressure sensor 39, the controller configured inside the machine body 1 will control the water-air mixing spray gun. 33. Water and gas are sprayed into the transfer box 34. The water and gas inside the transfer box 34 are depressurized through the water outlet 35, so that the water is sprayed through the water outlet 35 to the left and right sides of the cutting point between the cutting part 12 and the aluminum plate. This cools the aluminum plate. After the aluminum plate is removed, the pressure spring 4 pushes the moving plate 37 to reset it. Since the water sprayed onto the cutting point between the cutting part 12 and the aluminum plate can cool the aluminum plate and the blade of the cutting part 12, it avoids the aluminum plate from softening due to excessive temperature. The cooled strip-shaped material will fall more slowly, further reducing the possibility of the aluminum plate being torn at the cutting point.

[0036] Working principle: After the aluminum plate is placed above the rotating seat 13, the cylinder 21 is activated to pull the moving seat 23 downward until the extrusion plate 25 at the output end of the motor 24 contacts the top of the aluminum plate, so that the extrusion plate 25, together with the rotating seat 13, clamps the aluminum plate. If the area of ​​the aluminum plate is larger than the rotating seat 13, the part of the aluminum plate that exceeds the rotating seat 13 can be placed above the fixed column 291 and supported by the second ball bearing 293. When the cutting piece 12 stops moving, the aluminum plate will cover the upper left side of the transfer box 34 and extrude the moving plate 37. When the moving plate 37 retracts into the moving groove 36, the moving plate 37 will extrude the pressure spring 4. When the impact pin 38 on the lower side of the moving plate 37 contacts the pressure sensor 39, the water-air mixing spray gun 33 is controlled to spray water and air. The gas is injected into the transfer box 34, and the water and gas inside the transfer box 34 will be depressurized through the water outlet 35, so that the water is sprayed through the water outlet 35 to the cutting point between the cutting part 12 and the aluminum plate. During the cutting process of the cutting part 12 cutting the aluminum plate, the guide frame 27 guides the cut strip-shaped material. Then, after the extrusion plate 25 drives the aluminum plate to rotate, the strip-shaped material will gradually slide from the guide groove 271 into the connection between the guide frame 27 and the crushing box 26, and finally be uniformly processed inside the crushing box 26. During the cutting process of the cutting part 12 cutting the aluminum plate, because the two first balls 282 inside the positioning plate 281 are always at the cutting point of the cutting part 12 about to cut the aluminum plate, after the aluminum plate is cut, the two first balls 282 will press the connection between the aluminum plate and the strip-shaped material.

[0037] The above description is merely a preferred embodiment of the present invention; however, 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 its improved concepts, should be covered within the scope of protection of the present invention.
