Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and more specifically to a laser cutting device for processing aluminum veneer. Background Art

[0002] Aluminum veneer is a commonly used building material. It is a building material commonly used in the construction, decoration and advertising industries. It is usually made of aluminum alloy plates and has high strength, excellent corrosion resistance, light weight and good processability. However, the area size of aluminum veneer used in daily life is not fixed, and aluminum veneer is usually produced in standard fixed sizes. Therefore, before installation and laying, aluminum veneer will be cut from the corresponding aluminum veneer with suitable area according to the area of ​​use on site using cutting equipment.

[0003] At present, laser cutting is mainly used for cutting aluminum veneers. The working principle of laser cutting of aluminum veneers is mainly to irradiate the surface of the aluminum veneer with a high-power laser beam, so that it is heated to the melting point in a local area, and quickly evaporates or melts, thereby completing the cutting process. However, when facing the cutting of thicker aluminum veneers, the heat-affected zone generated by laser cutting is larger, and the metal in the cutting area may be heated too much, resulting in deformation or irregular cutting lines, thereby reducing the cutting quality of the aluminum veneer. At the same time, the material may be heated unevenly during the laser cutting process, especially high thermal conductivity metal such as aluminum, which can easily cause thermal expansion in the cutting area and cause material deformation. Especially when cutting thick aluminum veneers, the thermal deformation problem may be more serious, thereby affecting the use of the aluminum veneer after cutting. The existing technology generally uses suitable auxiliary gases to improve the cutting quality, but the use of auxiliary gases will increase production costs, especially when facing thicker aluminum veneers, specific auxiliary gases may require more consumption, thus increasing the cost of laser cutting of aluminum veneers.

[0004] In view of the above situation, the present invention designs a laser cutting device for aluminum single plate processing to solve the above technical problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a laser cutting device for processing aluminum veneer, which solves the problem that during the cutting process of thicker aluminum veneer, the heat affected zone generated by laser cutting of the aluminum veneer is large, resulting in deformation of the aluminum veneer or incomplete cutting, and even causing local burning or oxidation of the aluminum veneer due to changes in the material structure, thereby reducing the laser cutting quality.

The support seat is installed above the storage plate, and connecting springs are provided at the four corners of the support seat, one end of the connecting spring is fixedly connected to the storage plate, and the other end of the connecting spring is fixedly connected to the bottom of the support seat.

When facing a thicker aluminum veneer, the driving motor drives the transmission part to move, and the transmission part drives the flip mechanism to move, so that the storage plate is rotated 180° so that the laser can be used to laser cut the other side of the aluminum veneer. The laser makes a shallow cut on one side of the aluminum veneer, and then the processing surface of the aluminum veneer is converted through the storage plate, so as to cut the other side of the aluminum veneer, thereby avoiding one-time excessive heating and reducing the heat-affected zone. Double-sided switching for laser cutting can reduce the impact of thermal expansion and deformation, thereby reducing the deformation of the aluminum veneer that affects subsequent use, thereby improving the quality of laser-cut aluminum veneers.

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described example is a part of the embodiment of the present invention, rather than all the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] refer to Figures 1 to 6 As shown, a laser cutting device for aluminum veneer processing is used for double-sided cutting of aluminum veneer. A frame 11 is arranged at one end of the equipment body 1, and a connecting block 12 is arranged at the top of the frame 11. The connecting block 12 is slidably connected to the top of the frame 11, and the connecting block 12 can move on the surface of the frame 11 according to a preset path. A laser 13 for cutting aluminum veneer is arranged at one end of the connecting block 12 away from the surface of the frame 11; a driving motor 2 is arranged at one end of the bottom of the equipment body 1 away from the frame 11, and a transmission member 3 is connected to the output end of the driving motor 2. A flip mechanism 4 is arranged on both sides of the transmission member 3. The driving motor 2 rotates through the transmission member 3 to drive the flip mechanism 4 to move, and a useful A storage plate 5 for installing an aluminum single plate is provided with a clamping assembly 6 at the upper end of the storage plate 5, and the clamping assembly 6 is used to apply a uniform clamping force to the circumferential surface of the aluminum single plate; when the laser cuts a thicker aluminum single plate, the laser 13 is driven by the connecting block 12 to cut one side of the aluminum single plate on the clamping assembly 6. After the laser 13 cuts a certain depth, the driving motor 2 rotates to drive the flipping mechanism 4 to move through the transmission member 3. The movement of the flipping mechanism 4 causes the aluminum single plate on the clamping assembly 6 to turn over, so that the laser 13 performs laser cutting on the other side of the aluminum single plate, thereby effectively reducing the reflected heat damage generated by the laser 13 when cutting the aluminum single plate, and improving the cutting effect of the laser 13 in cutting the aluminum single plate.

[0024] Specifically, the transmission member 3 includes a double gear 31, a number one driven gear 32, a number two driven gear 33 and a transmission belt 34. The driving motor 2 is horizontally arranged on the surface of the equipment body 1, and the output end of the driving motor 2 is coaxially connected with the double gear 31. A number one driven gear 32 and a number two driven gear 33 are arranged on both sides of the double gear 31. The number one driven gear 32 and the number two driven gear 33 are respectively connected to the double gear 31 through a transmission belt 34. The rotation of the driving motor 2 drives the double gear 31 to move synchronously, and the double gear 31 drives the number one driven gear 32 and the number two driven gear 33 to rotate respectively through the transmission belt 34.

[0025] Specifically, the flip mechanism 4 includes a fixing frame 41, a screw rod 42, a support plate 43, a control block 44, a control rod 45 and a connecting block 12. The fixing frames 41 are symmetrically arranged on both sides of the equipment body 1. The fixing frames 41 on both sides are arranged on the side away from the frame 11. The screw rod 42 is arranged inside the fixing frame 41. The screw rod 42 penetrates the support plate 43 and is rotatably arranged on the support plate 43. The first driven gear 32 and the second driven gear 32 are respectively arranged on the screw rods 42 on both sides. The driving gear 33, and a connecting column 46 is provided on one side of the No. 1 driven gear 32 and the No. 2 driven gear 33, the bottom end of the connecting column 46 is fixedly connected to the device body 1, and the top of the connecting column 46 is rotatably connected to a control rod 45, and the control rod 45 is an L-shaped structure 451, one end of the control rod 45 is rotatably connected to the connecting column 46, and the other end of the control rod 45 is rotatably connected to the storage plate 5, and the storage plate 5 is symmetrically rotatably provided with a control block 44 away from one end of the control rod 45, and the control block 44 is coaxially arranged with the spiral rods 42 on both sides.

[0026] Specifically, the control block 44 is a rectangular structure, and the control block 44 is arranged in contact with the inner wall of the fixing frame 41. When the spiral rod 42 rotates to drive the control block 44 to move inside the fixing frame 41, the control block 44 pushes the storage plate 5 to rotate on the control rod 45 to change the angle of the storage plate 5.

[0027] Specifically, the clamping assembly 6 includes a support seat 61, a connecting spring 62, a rotating plate 63, a V-shaped rod 64 and a moving block 65. The support seat 61 is installed above the storage plate 5, and connecting springs 62 are provided at the four corners of the support seat 61, one end of the connecting spring 62 is fixedly connected to the storage plate 5, and the other end of the connecting spring 62 is fixedly connected to the bottom of the support seat 61. The support seat 61 is in an "I" shape, and a rotating plate 63 is rotatably provided in the middle of the support seat 61, and V-shaped rods 64 are rotatably provided at the four corners of the rotating plate 63. The moving block 65 is connected to the end of the V-shaped rod 64 away from the rotating plate 63. A plurality of moving grooves 611 are opened at the top of the support seat 61, and the moving block 65 is arranged in the moving groove 611. When any moving block 65 moves, the moving block 65 drives the V-shaped rod 64 to rotate, so that the V-shaped rod 64 drives the rotating plate 63 to rotate, and the rotation of the rotating plate 63 drives the remaining V-shaped rods 64 to move synchronously. At this time, the remaining moving blocks 65 all move in the moving groove 611.

[0028] Specifically, one end of the moving block 65 is connected to a control spring 66, and the end of the control spring 66 away from the moving block 65 is connected to a clamping block 67. Multiple moving blocks 65 move synchronously to drive the clamping block 67 to fit the outer side of the aluminum plate, thereby evenly applying clamping force to the aluminum plate.

[0029] Specifically, a blanking hole 612 is opened on the support seat 61, and a through hole 51 is opened on the placement plate 5. The diameter of the blanking hole 612 is consistent with that of the through hole 51. When the laser 13 cuts the aluminum single plate, the cut residue can be discharged through the blanking hole 612 and the through hole 51.

[0030] Specifically, a threaded hole is provided on the moving block 65 , and the threaded hole can be connected via an external driving device, and the moving block 65 can be driven to reciprocate in the moving groove 611 via the external driving device.

[0031] Working process and principle; before the work starts, the operator first places the aluminum single plate on the support seat 61, and drives the moving block 65 to move in the moving groove 611 on the support seat 61 through an external driving device. The movement of the moving block 65 drives its corresponding V-shaped rod 64 to rotate, and the rotation of the V-shaped rod 64 drives the rotating plate 63 to move synchronously. The rotation of the rotating plate 63 drives the remaining V-shaped rods 64 to rotate, and the rotation of the V-shaped rod 64 drives the remaining moving blocks 65 to move in the moving groove 611. At this time, since a control spring 66 is provided at one end of the moving block 65, and the control spring 66 is connected to the clamping block 67, the multiple clamping blocks 67 can evenly apply clamping force to the outer side of the aluminum single plate to avoid the deformation of the aluminum single plate caused by uneven clamping force. Through the connecting spring 62 provided at the bottom of the support seat 61, the aluminum single plate can be suspended above the storage plate 5. At this time, the aluminum single plate is cut by the laser 13, which can avoid the laser 13 burning the surface of the storage plate 5 due to long-term laser cutting; When the thickness of the aluminum veneer to be cut is relatively thin, at this time, it is only necessary to drive the laser 13 to move on the top of the frame 11 through the connecting block 12, so that the laser 13 cuts the aluminum veneer according to the preset path, and the cutting of the aluminum veneer can be completed. When the thickness of the aluminum veneer to be cut is relatively thick, at this time, the laser 13 first performs laser cutting on one side of the aluminum veneer. After cutting to a certain depth, in order to avoid a large heat-affected zone during cutting, the double gear 31 is driven to rotate by the driving motor 2. The rotation of the double gear 31 drives the first driven gear 32 and the second driven gear 33 to rotate through the transmission belt 34. Since the first driven gear 32 and the second driven gear 33 are respectively fixedly connected to the screw rod 42, the screw rods 42 on both sides rotate at this time, and the rotation of the screw rod 42 drives the control block 44 to move on the inner wall of the fixed frame 41. At this time, the storage plate 5 is driven by the control block 44 so that the storage plate 5 rotates on the control block 44 and the control plate , so that the storage plate 5 is changed from a horizontal state to a vertical state, and the control rod 45 swings upward. When the control block 44 moves from one end of the spiral rod 42 to the other end of the spiral rod 42, the storage plate 5 flips 180° to expose the uncut side to the cutting area of ​​the laser 13. At this time, the laser 13 is controlled to cut the aluminum veneer according to the preset path, so that the quality of the cut aluminum veneer is not affected by the heat-affected zone and deformed, thereby ensuring the quality of the laser-cut aluminum veneer. When the cutting is completed, the spiral rod 42 is driven to flip by controlling the driving motor 2 to reverse, so that the storage plate 5 is flipped, so that the clamping assembly 6 remains in a horizontal upward state, and the moving block 65 is driven to move. The movement of the moving block 65 drives the clamping block 67 to cancel the clamping of the aluminum veneer, and then the remaining aluminum veneer is removed. The double-sided cutting method can effectively improve the quality of the laser-cut aluminum veneer and avoid the cut aluminum veneer from not meeting the use conditions.

The protection scope of the present invention is defined by the claims.
