Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting, and specifically relates to a profiling cutting device for automotive decorative panels and its control method. Background Art

[0002] Laser cutting is a method of using a highly focused high-power density laser beam to irradiate a workpiece, causing the irradiated material to quickly melt, vaporize or reach the ignition point. At the same time, molten material is blown away by a high-speed gas flow coaxial with the beam, thereby realizing the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces. It is divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture. For existing metal automotive decorative panels, the metal plate needs to be cut first during preparation, usually using laser profiling cutting, that is, cutting the metal plate into a specified shape, and then stamping the cut metal plate into the required form through a mold.

[0003] During the actual cutting operation of the metal plate, the metal plate needs to be supported by a steel tooth plate, and the cutting will generate high-temperature debris. When the high-temperature debris contacts the steel tooth plate, it will adhere to the surface of the steel tooth plate.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0022] As Figures 1 to 4 As shown in the figure, a profiling cutting device for an automotive decorative panel and its control method according to an embodiment of the present invention includes a base 1. A plurality of steel tooth plates 13 are arranged at the top of the base 1. A bracket assembly 11 is arranged above the base 1, and a laser cutting head 12 is installed on the bracket assembly 11; A positioning plate 2 is arranged on one side of the base 1. A first connecting piece 21 is arranged on the side of the positioning plate 2. A material receiving box 22 is arranged at the end of the first connecting piece 21. The material receiving box 22 is inserted between adjacent steel tooth plates 13, and the distance between adjacent steel tooth plates 13 is the same as the width of the material receiving box 22; when the material receiving box 22 is inserted between adjacent steel tooth plates 13, both ends are located outside the base 1; the top of the material receiving box 22 is at the same height as the top of the steel tooth plate 13; In the embodiment of the present invention, the material receiving box 22 is provided. Since the distance between adjacent steel tooth plates 13 is the same as the width of the material receiving box 22; after the material receiving box 22 is inserted between the steel tooth plates 13, both sides are in contact with the side surfaces of the steel tooth plates 13. During the cutting operation, the metal plate is placed on the top of the steel tooth plate 13. As the laser cutting head 12 cuts the metal plate, the generated metal debris falls downward below the metal plate and is then received by the material receiving box 22. The material receiving box 22 receives the high-temperature metal debris, effectively preventing the high-temperature metal debris from adhering to the surface of the steel tooth plate 13. After using for a period of time, the material receiving box 22 can be disassembled and replaced. The material receiving box 22 is made of plastic, with low cost and can be used in large quantities; therefore, the material receiving box 22 can be arranged between adjacent steel tooth plates 13, which can effectively improve the service life of the steel tooth plate 13.

[0023] A high-temperature resistant metal sheet is attached to the top of the material receiving box 22; when the metal plate is placed on the top of the steel tooth plate 13, since the top of the material receiving box 22 is at the same height as the top of the steel tooth plate 13, the top of the material receiving box 22 can be in contact with the bottom surface of the metal plate. When cutting the metal plate, the metal plate generates high temperature, and a high-temperature resistant metal sheet is attached to the top of the material receiving box 22. Therefore, the high-temperature resistance of the material receiving box 22 is improved, ensuring the use effect.

[0024] As Figures 1 to 4As shown, the first connecting member 21 is specifically a hydraulic cylinder; the housing part of the hydraulic cylinder is installed on the side of the positioning plate 2, and the output end of the hydraulic cylinder is connected to the material receiving box 22; during use, the hydraulic cylinder can drive the material receiving box 22 to reciprocate between adjacent steel tooth plates 13, that is, the material receiving box 22 continuously moves relative to the steel tooth plates 13, preventing high-temperature debris from falling between the steel tooth plates 13 and the material receiving box 22 and sticking and fixing the two, which is convenient for the removal of the material receiving box 22 later.

[0025] As Figures 3 to 10 shown, an air extraction head 3 is arranged inside the material receiving box 22. The air extraction head 3 is installed at the end position inside the material receiving box 22. A first air pipe 31 is communicated with the side of the air extraction head 3, and the first air pipe 31 is externally connected to a first air pump; A plurality of grooves are formed in the inner wall of the material receiving box 22. An intercepting rod 32 is rotatably arranged in the grooves. The intercepting rod 32 is used for receiving debris generated by laser cutting; a weight plate 321 is fixedly connected to the bottom end of the intercepting rod 32, and an oscillating plate 322 is arranged on the side of the weight plate 321; a toothed ring 34 is sleeved on the end of the intercepting rod 32, and a rack 35 engaged with the toothed ring 34 is fixedly connected to the inner wall of the material receiving box 22; During use, start the first air pump connected to the first air pipe 31. The first air pump sucks air through the first air pipe 31 to the air extraction head 3, and the air extraction head 3 sucks air from the material receiving box 22, causing the falling debris to concentrate into the material receiving box 22. When it contacts the intercepting rod 32 in the material receiving box 22, it adheres to the surface of the intercepting rod 32, realizing the centralized collection of high-temperature debris and improving the collection effect. The setting of the intercepting rod 32 enables high-temperature debris at different positions to be quickly received when falling into the interior of the material receiving box 22, preventing high-temperature debris from concentrating in one place under the action of air flow and affecting the debris collection process. In addition, when the air extraction head 3 sucks air from the material receiving box 22, the dropping plate 321 is driven by the air flow to drive the intercepting rod 32 to rotate. When the dropping plate 321 rotates, it drives the oscillating plate 322 to rotate synchronously. When the oscillating plate 322 rotates, the bottom end will hit the surface of the intercepting rod 32 below, causing the intercepting rod 32 to oscillate, thereby driving the high-temperature debris adhering to the intercepting rod 32 to fall off. In addition, when the intercepting rod 32 rotates, the toothed ring 34 at the end of the intercepting rod 32 meshes with the toothed plate 35 for transmission, causing the intercepting rod 32 to move upward. As the intercepting rod 32 returns to its original position and rotates, when the intercepting rod 32 moves up and down, the end is located in the groove, and the groove reserves a moving space. When the intercepting rod 32 moves up and down, it will drive the oscillating plate 322 to move synchronously. Initially, the bottom end of the oscillating plate 322 contacts the intercepting rod 32 below. Therefore, the oscillating plate 322 will intermittently hit the intercepting rod 32 below, further improving the oscillation effect of the intercepting rod 32. At the same time, the vibration of the intercepting rod 32 will cause the material receiving box 22 to oscillate synchronously, so the high-temperature debris adhering to the inner wall of the material receiving box 22 will vibrate synchronously, driving it to fall downward and preventing the high-temperature debris from accumulating on the inner wall of the material receiving box 22 and affecting the continuous use of the material receiving box 22, which is beneficial to the use of the material receiving box 22. It should be noted that during this process, it is necessary to control the output power of the first air pump connected to the first air pipe 31 so that the air flow intensity in the material receiving box 22 increases and decreases intermittently. When the air flow intensity in the material receiving box 22 decreases, the dropping plate 321 rotates back to its original position under its own gravity, causing the oscillating plate 322 to disengage from the intercepting rod 32. Then, when the air flow intensity increases, the dropping plate 321 repeats driving the intercepting rod 32 to twist, causing the oscillating plate 322 to repeatedly hit the intercepting rod 32 below, making the intercepting rod 32 and the material receiving box 22 continuously oscillate to ensure the use effect.

[0026] A filter screen 33 is arranged inside the material receiving box 22, and the filter screen 33 is arranged at the air extraction port position of the air extraction head 3. By setting the filter screen 33, it can prevent the air extraction head 3 from sucking high-temperature debris into the interior and causing blockage of the air extraction head 3.

[0027] A cavity plate 4 is arranged on the inner bottom wall of the material receiving box 22. A cavity is formed inside the cavity plate 4, and a second air pipe 41 is arranged at the top of the cavity plate 4. The second air pipe 41 is communicated with the cavity, and a second air pump is connected to the second air pipe 41 externally. A plurality of air holes are evenly formed at the top end of the cavity plate 4; the filter screen 33 is located between the air extraction head 3 and the cavity plate 4; During use, start the second air pump externally connected to the second air pipe 41. The second air pump fills the cavity inside the cavity plate 4 with external water vapor through the second air pipe 41; then the water vapor sprays upward through the air holes at the top end of the cavity plate 4, so that the high-temperature debris entering the inside of the material receiving box 22 is quickly cooled and hardened, preventing the high-temperature debris from contacting the filter screen 33 and adhering to the surface of the filter screen 33 to block the filter screen 33; at the same time, the water vapor will also wet the intercepting rod 32, and cooperate with the vibration of the intercepting rod 32 to effectively prevent the high-temperature debris from adhering to the surface of the intercepting rod 32, which is beneficial to the continuous use of the intercepting rod 32; improve the collection ability of the material receiving box 22 for debris; in addition, the harmful gases generated by laser cutting can also be extracted and transferred through the air extraction head 3, optimizing the air quality in the cutting operation area.

[0028] A diversion pipe 5 is provided through the end of the material receiving box 22, and the end of the diversion pipe 5 located inside the material receiving box 22 penetrates between the filter screen 33 and the cavity plate 4; the water vapor sprayed out through the cavity plate 4 will finally fall and concentrate in the material receiving box 22 and form liquid water, and then is guided to separate from the material receiving box 22 through the diversion pipe 5.

[0029] Grooves 62 with the same tooth shape and size as the teeth of the steel tooth plate 13 are formed on both sides of the material receiving box 22. A plurality of conduction heads 6 are provided through the top end of the cavity plate 4. The bottom end of the conduction head 6 is communicated with the cavity of the cavity plate 4, and a spray head 61 is provided at the top end of the conduction head 6. Initially, the spray port of the spray head 61 points to the groove 62; during use, the conduction head 6 can receive the water vapor inside the cavity plate 4 and spray it out through the spray head 61. The sprayed water vapor can enter the inside of the teeth of the steel tooth plate 13 through the groove 62 and wet the inner wall of the teeth of the steel tooth plate 13, thereby preventing the high-temperature debris falling into the inside of the teeth of the steel tooth plate 13 from adhering to the teeth, and effectively restricting the accumulation of debris in the teeth of the steel tooth plate 13, which is beneficial to improving the service life of the steel tooth plate 13.

[0030] As Figure 11 shown, a control method for profiling cutting of an automotive decorative panel includes the following steps: S1. During cutting operation, insert the material receiving box 22 between adjacent steel tooth plates 13; S2. Then place the metal plate to be cut above the steel tooth plate 13; then start the laser cutting device; S3. At the same time, start the first air pump externally connected to the first air pipe 31. The first air pump evacuates the air extraction head 3 through the first air pipe 31; S4. At the same time, start the second air pump externally connected to the second air pipe 41. The second air pump fills the cavity inside the cavity plate 4 with external water vapor through the second air pipe 41; S5. When the cutting is completed, unload the profiled metal plate cut out from the steel tooth plate 13.

[0031] During operation, during the cutting operation, the metal plate is placed on the top of the steel tooth plate 13. As the laser cutting head 12 cuts the metal plate, the generated metal debris falls downward from the metal plate and is then received by the material receiving box 22. The material receiving box 22 receives the high-temperature metal debris, effectively preventing the high-temperature metal debris from adhering to the surface of the steel tooth plate 13. After being used for a period of time, the material receiving box 22 can be disassembled and replaced. The material receiving box 22 is made of plastic, with a low cost and can be used in large quantities. Therefore, the material receiving box 22 can be arranged between adjacent steel tooth plates 13, effectively improving the service life of the steel tooth plate 13. A high-temperature resistant metal sheet is attached to the top of the material receiving box 22. When the metal plate is placed on the top of the steel tooth plate 13, since the top of the material receiving box 22 is at the same height as the top of the steel tooth plate 13, the top of the material receiving box 22 can contact the bottom surface of the metal plate. When cutting the metal plate, the metal plate generates high temperature, and a high-temperature resistant metal sheet is attached to the top of the material receiving box 22, thus improving the high-temperature resistance of the material receiving box 22 and ensuring the use effect. The first connecting member 21 is specifically a hydraulic cylinder. The housing part of the hydraulic cylinder is installed on the side of the positioning plate 2, and the end of the output end of the hydraulic cylinder is connected to the material receiving box 22. During use, the hydraulic cylinder can drive the material receiving box 22 to reciprocate between adjacent steel tooth plates 13, that is, the material receiving box 22 continuously moves relative to the steel tooth plate 13, preventing high-temperature debris from falling between the steel tooth plate 13 and the material receiving box 22 and sticking them together, facilitating the removal of the material receiving box 22 later.

[0032] When in use, the first air pump connected to the first air pipe 31 is started, and the first air pump evacuates the air to the exhaust head 3 through the first air pipe 31, and the exhaust head 3 evacuates the air to the receiving box 22, so that the fallen debris is concentrated in the receiving box 22, and adheres to the surface of the intercepting rod 32 when it contacts with the intercepting rod 32 in the receiving box 22, so that the high-temperature debris is collected in a centralized manner and the collection effect is improved; and the setting of the intercepting rod 32 can make the high-temperature debris at different positions quickly be received when it falls into the receiving box 22, so as to avoid the high-temperature debris from falling into the receiving box 22 under the action of airflow The debris is concentrated in one place, which affects the debris collection process; wherein the interior of the receiving box 22 is provided with a filter screen 33, and the filter screen 33 is arranged at the air suction port position of the air suction head 3; by setting the filter screen 33, it is possible to prevent the air suction head 3 from sucking high-temperature debris into the interior, causing blockage of the air suction head 3; wherein when in use, the second air pump connected to the second air pipe 41 is started, and the second air pump fills the external water vapor into the cavity inside the cavity plate 4 through the second air pipe 41; then the water vapor is ejected upward through the air hole at the top of the cavity plate 4, so that it enters the receiving box The high-temperature debris inside 22 is quickly cooled and hardened, preventing the high-temperature debris from contacting the filter 33 and adhering to the surface of the filter 33, thereby clogging the filter 33; at the same time, the water vapor will wet the interception rod 32, preventing the high-temperature debris from adhering to the surface of the interception rod 32, which is beneficial to the continuous use of the interception rod 32; improving the collection capacity of the material receiving box 22 for debris; in addition, the harmful gases generated by laser cutting can also be extracted and transferred through the exhaust head 3, thereby optimizing the air quality in the cutting operation area; the water vapor ejected through the cavity plate 4 will finally fall and concentrate In the receiving box 22, liquid water is formed, and then it is guided out of the receiving box 22 through the guide tube 5; when in use, the conductive head 6 can receive the water vapor inside the cavity plate 4, and spray it out through the nozzle 61, and the sprayed water vapor can enter the interior of the steel tooth plate 13 teeth through the groove 62, and wet the inner wall of the steel tooth plate 13 teeth, thereby preventing high-temperature debris that falls into the interior of the steel tooth plate 13 teeth from adhering to the teeth, thereby effectively limiting the accumulation of debris in the teeth of the steel tooth plate 13, which is beneficial to improving the service life of the steel tooth plate 13.
