Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting platform for stainless steel sheets and its laser cutting equipment. Background Technology

[0002] A stainless steel sheet laser cutting platform is a modular support device that is installed on the bed of a laser cutting machine tool, supports and positions the stainless steel sheet to be processed through multi-point support or continuous planar contact, and has the characteristics of high rigidity, ablation resistance, and easy maintenance. It can also work with a dust removal system to collect cutting slag. Laser cutting equipment for stainless steel sheets is a specialized processing equipment that uses an optical system to focus a specific wavelength laser beam onto the surface of a stainless steel sheet, causing a localized area to melt, vaporize, or reach its ignition point. The molten metal is then blown away with coaxial high-pressure auxiliary gas to form a high-quality kerf. Under the control of a computer numerical control system, it completes the cutting of complex contours along a predetermined path.

[0003] However, the stainless steel sheet laser cutting platform uses multiple serrated strips to support the stainless steel sheet. When the stainless steel sheet is placed on these serrated strips, its lower end will contact the teeth on the strips. If this contact point is located on the cutting path, the laser beam penetrating the stainless steel sheet will directly act on the serrated strips during the laser cutting process, causing damage and reducing its lifespan. Furthermore, if burrs appear on the cut surface during laser cutting, additional grinding is required afterward, affecting the production efficiency of the stainless steel sheet products. Therefore, this does not meet the existing requirements. To address this, we propose a stainless steel sheet laser cutting platform and its laser cutting equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cutting platform for stainless steel sheets and a laser cutting device thereof, to solve the problems mentioned in the background art, such as the use of multiple serrated strips to support stainless steel sheets on the laser cutting platform, where the lower end face of the stainless steel sheet will contact the teeth on the serrated strips when the stainless steel sheet is placed on them, and if the contact point is exactly on the cutting path, then during the laser cutting process, the laser beam penetrating the stainless steel sheet will directly act on the serrated strips, thereby damaging it and reducing its service life. Furthermore, if burrs appear on the cut surface during laser cutting, additional grinding is required after laser cutting, thus affecting the production efficiency of stainless steel sheet products.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, before using the equipment, sets the tops of the teeth on the first and second placement serrated plates as contact points and records their layout data into the control console. When the laser cutting head travels along a preset cutting path on the stainless steel sheet, the CNC system of the control console analyzes the cutting path coordinate data in real time, predicts the spatial relationship between the laser beam and the first and second placement serrated plates. If a tooth on a certain first placement serrated plate is within the cutting path of the laser cutting head and will cut through the stainless steel sheet and come into contact with it within the next three seconds, the avoidance-type support pushing mechanism pushes all the second placement serrated plates upwards. A serrated plate is used to support the stainless steel sheet, and the first serrated plate is moved downward to remove the teeth on the first serrated plate from the laser action area. Conversely, the second serrated plate is moved downward and the first serrated plate is moved upward. This technical solution can prevent the laser penetrating the stainless steel sheet from directly acting on the teeth on the first and second serrated plates, thereby improving the service life of the first and second serrated plates on the equipment. It can also prevent the molten metal from rebounding to the bottom surface of the stainless steel sheet and forming slag after the teeth on the first or second serrated plate are burned by the laser. 2. The present invention, when burrs appear on the surface of the opening cut by the laser cutting head, can automatically control the rotating burr grinding wheel to move along the moving trajectory of the laser cutting head through the grinding wheel guide mechanism, thereby grinding the burrs on the opening surface. The above technical solution can simultaneously grind the burrs during the cutting operation, thereby improving the efficiency of stainless steel product production. Attached Figure Description

When the first placement serrated plate 201 is aligned with the second placement serrated plate 202, the first placement serrated plate 201 is stopped at the current position and then the second placement serrated plate 202 is moved downward. Above the avoidance and protection saw tooth support mechanism 2, there is a movable frame 4. An automatic deburring laser cutting mechanism is installed at the middle position of the lower end face of the movable frame 4. The automatic deburring laser cutting mechanism includes a laser cutting head 15, a deburring grinding wheel 14 and a grinding wheel guide mechanism.

When the equipment is needed, the stainless steel plate 5 is placed on the upper end face of the avoidance and protection saw tooth support mechanism 2, and then the laser cutting head 15 is started to emit a cutting beam. The laser cutting head 15 is controlled to move along the cutting trajectory on the stainless steel plate 5 by the moving frame 4 and the slider 16, so as to perform laser cutting on the stainless steel plate 5.

[0021] The avoidance-type support pushing mechanism includes two strip-shaped housings 203. A pushing cylinder 206 is fixedly installed on both sides inside each of the two strip-shaped housings 203. The piston rods of the two pushing cylinders 206, fixedly installed inside the same strip-shaped housing 203, are connected to a pushing plate 207. A through hole 208 is provided on the outer surface of the pushing plate 207 at a position corresponding to the first placement serrated plate 201. A metal rod 209, whose lower end face is fixed to the strip-shaped housing 203, is provided inside the through hole 208. A first spring 210 is sleeved on the outer surface of the metal rod 209. A first serrated fixing plate 204, movably sleeved on the outer surface of the metal rod 209, is connected to the upper end face of the first spring 210. Multiple first serrated fixing plates 204 are also provided. The position of the sawtooth fixing plate 204 corresponds to the position of the multiple first placement sawtooth plates 201. The upper end face of the first sawtooth fixing plate 204 and the upper end face of the first placement sawtooth plate 201 are on the same horizontal line, and the surface of the first sawtooth fixing plate 204 facing the first placement sawtooth plate 201 is fixed to the first placement sawtooth plate 201. Both sides of the first sawtooth fixing plate 204 are provided with a push rod 211 fixed to the upper end face of the push plate 207. The upper end face of the push rod 211 is a first inclined surface 212. Above the first inclined surface 212, there is a push block 213 whose upper end face is slidably connected to the strip shell 203. The push block 213 is fixed towards the nearest first sawtooth. The surface of plate 204 is a second inclined surface 214. A pressing and pushing block 215, fixed to the outer surface of the first sawtooth fixing plate 204, is provided on one side of the second inclined surface 214. A metal column 216, fixed to the upper end face of the pushing plate 207, is provided on one side of the through hole 208. A spring groove 217 is provided inside the metal column 216, containing a second spring 218. A circular plate 219 is connected to the upper end face of the second spring 218. A connecting rod 220 is fixedly connected to the axis of the circular plate 219. A second sawtooth fixing plate 205 is fixed to the upper end face of the connecting rod 220. A limiting sleeve 222 is fixedly sleeved on the lower side of the outer surface of the second sawtooth fixing plate 205, and a limiting sleeve 222 is provided on the outer side of the limiting sleeve 222. The limiting groove 221 is located inside the strip-shaped outer shell 203; the positions of multiple second sawtooth fixing plates 205 correspond to the positions of multiple second placement sawtooth plates 202 respectively, the upper end face of the second sawtooth fixing plate 205 and the upper end face of the second placement sawtooth plate 202 are on the same horizontal line, and the surface of the second sawtooth fixing plate 205 facing the second placement sawtooth plate 202 is fixed to the second placement sawtooth plate 202; the height difference between the upper end face of the first sawtooth fixing plate 204 and the upper end face of the second sawtooth fixing plate 205 is the same as the distance from the upper end face of the first inclined surface 212 to the lower end face of the push block 213 and the distance between the upper end face of the limiting sleeve 222 and the upper inner wall of the limiting groove 221;When the stainless steel plate 5 is placed on the avoidance and protection saw tooth support mechanism 2, since the first placement saw tooth plate 201 is higher than the second placement saw tooth plate 202, after the stainless steel plate 5 is placed, only the teeth on the first placement saw tooth plate 201 are in contact with the stainless steel plate 5. Before using the equipment, the tops of the teeth on the first placement serrated plate 201 and the second placement serrated plate 202 are set as contact points, and their layout data is entered into the internal control console 3. When the laser cutting head 15 moves along the preset cutting path on the stainless steel plate 5, the CNC system of the control console 3 analyzes the cutting path coordinate data in real time, predicts the spatial relationship between the laser beam and the first placement serrated plate 201 and the second placement serrated plate 202, and determines if a tooth on a certain first placement serrated plate 201 is within the cutting path of the laser cutting head 15 and will cut through it within the next three seconds. When the stainless steel plate 5 comes into contact with it, the push cylinders 206 installed inside the two strip-shaped housings 203 are activated. At this time, the push cylinders 206 push the push plate 207 upward. As the push plate 207 rises, the metal column 216 fixed to the upper surface of the push plate 207 and the second serrated fixing plate 205 connected to the second spring 218 located inside the metal column 216 through the circular plate 219 and the connecting rod 220 will move upward together. When the second serrated fixing plate 205 moves upward, the second placement serrated plate 202 fixed to it will also move upward together. Since the first placement serrated plate 201 and the second placement serrated plate 202 are aligned with the first serrated fixing plate 204 and the second serrated fixing plate 205 respectively, and the height difference between the upper end face of the first serrated fixing plate 204 and the upper end face of the second serrated fixing plate 205 is the same as the distance between the upper end face of the limiting sleeve 222 fixed on the outer surface of the second serrated fixing plate 205 and the upper inner wall of the limiting groove 221, when the second placement serrated plate 201 is fixed to the second serrated fixing plate 205... After the teeth on the serrated plate 202 are in contact with the lower end face of the stainless steel plate 5, the upper end face of the limiting sleeve 222, which is fixedly sleeved on the outer surface of the second serrated fixing plate 205, will be in contact with the upper inner wall of the limiting groove 221. This will cause the second serrated plate 202 to be unable to continue to move upward as the push plate 207 rises. At this time, as the push plate 207 continues to rise, the circular plate 219 will gradually penetrate into the spring groove 217 and squeeze the second spring 218. As the push plate 207 rises, the push rod 211 fixed to the upper surface of the push plate 207 will gradually approach the push block 213. When the first inclined surface 212 on the push rod 211 comes into contact with the push block 213, the push block 213 will be gradually pushed inward as the push rod 211 continues to rise. When the push block 213 is gradually pushed inward, the second inclined surface 214 on the outer surface of the push block 213 will contact the pressing push block 215 fixed to the outer surface of the first sawtooth fixing plate 204 and push the pressing push block 215 and the first sawtooth fixing plate 204 downward. When the first sawtooth fixing plate 204 moves downward, the first placement sawtooth plate 201 directly fixed to it will move downward along with it. Since the lower end face of the first sawtooth fixing plate 204, which is directly fixed to the first placement sawtooth plate 201, is connected to the first spring 210, when the push rod 211 is pushed upward by the push cylinder 206 and before the push rod 211 contacts the push block 213, the overall height of the first sawtooth fixing plate 204 and the first placement sawtooth plate 201 fixed thereto will not change. Only after the upper end face of the second placement sawtooth plate 202 contacts the stainless steel plate 5 and the push rod 211 contacts the push block 213, the first placement sawtooth plate 201 will be pushed downward as the push plate 207 continues to rise. At the same time, when the first placement sawtooth plate 201 is pushed downward, it will squeeze the first spring 210 connected to it. At this time, the stainless steel plate 5 is supported by the second placement serrated plate 202, and all the first placement serrated plates 201 are moved downward to remove the teeth on the first placement serrated plates 201 from the laser action area. The above technical solution can prevent the laser penetrating the stainless steel plate 5 from directly acting on the teeth of the first placement saw blade 201 and the second placement saw blade 202, thereby improving the service life of the first placement saw blade 201 and the second placement saw blade 202 on the equipment. At the same time, it can also prevent the molten metal from rebounding to the bottom surface of the stainless steel plate 5 and forming slag after the teeth of the first placement saw blade 201 or the second placement saw blade 202 are burned by the laser. If the teeth on the second placement serrated plate 202 come into contact with the laser beam penetrating the stainless steel plate 5, the electric ring 6 pulls the push plate 207 downward. As the push plate 207 and the push rod 211 fixed to the upper surface of the push plate 207 gradually descend, the first serrated fixing plate 204, which is pushed downward by the push rod 211, will gradually move upward under the spring force of the compressed first spring 210 until the upper surface of the first placement serrated plate 201, which is fixed to the first serrated fixing plate 204, is once again in contact with the lower surface of the stainless steel plate 5, so as to support the stainless steel plate 5 again through the first placement serrated plate 201. As the push plate 207 moves downward, the metal column 216, which is also fixed to it, will move downward along with it. When the metal column 216 moves downward, it can gradually push the circular plate 219 upward by the spring force of the compressed second spring 218 until the upper end surface of the circular plate 219 is in contact with the upper inner wall of the spring groove 217. When the two are in contact with each other, the circular plate 219 itself can no longer move upward inside the metal column 216 under the operation of the spring force of the second spring 218. At this time, the second sawtooth fixing plate 205, which is connected to the circular plate 219 by the connecting rod 220, will be pulled downward. When the second sawtooth fixing plate 205 moves downward, the second placement sawtooth plate 202 will gradually move downward. As the second placement sawtooth plate 202 descends, the teeth on the second placement sawtooth plate 202 will gradually leave the laser action area. Furthermore, due to the spring force of the second spring 218, when the push plate 207 just moves downward, the second placement serrated plate 202 will not move downward along with it. The spring force of the second spring 218 here can prevent the stainless steel plate 5 supported by the second placement serrated plate 202 from moving downward.

[0022] A ring of monitoring cameras 17 is fixed to the lower end face of the moving frame 4 on the outer side of the laser cutting head 15; during the laser cutting process, the cutting opening can be monitored in real time through the ring of monitoring cameras 17 located on the outer side of the laser cutting head 15.

[0023] The grinding wheel guiding mechanism includes an electric ring 6, with an annular shell 7 fixedly fitted on the outer side of the electric ring 6. A strip groove 8 is provided on one side of the outer surface of the annular shell 7, and an electric slider 9 is slidably installed inside the strip groove 8. A small lifting electric slider 10 is fixedly installed on both sides inside the electric slider 9. A cylindrical shell 11 is fixed between the two small lifting electric sliders 10. A grinding motor 12 is fixedly installed on the upper side inside the cylindrical shell 11. The output shaft of the grinding motor 12 is connected to a motor shaft 13 through a coupling. A burr grinding wheel 14 is fixedly fitted on the lower end face of the outer surface of the motor shaft 13. The electric ring 6 itself can drive the annular shell 7 and the burr grinding wheel 14 installed on the annular shell 7 to revolve around the laser cutting head 15. The electric slider 9 includes a metal shell, a drive motor for movement, and a moving roller. The drive motor for movement is fixedly installed inside the metal shell, and the moving roller is fixedly sleeved on the outer surface of the shaft of the drive motor for movement, with the outer surface of the moving roller in contact with the inner wall of the strip groove 8. The drive motor inside the electric slider 9 can drive the moving roller, whose outer surface is in contact with the inner wall of the strip groove 8, to rotate, thereby driving the entire electric slider 9 to move along the strip groove 8. The small lifting electric slider 10 includes a slide rail and an electric slider, which is slidably mounted on the outer surface of the slide rail; and the electric slider can drive the cylindrical housing 11 fixed between two small lifting electric sliders 10 to move up and down along the slide rail. If a burr is detected at the cut edge by the monitoring camera 17, the control console 3 will automatically control the grinding motor 12 to drive the burr grinding wheel 14 connected to it through the motor shaft 13 to rotate, and move the small lifting electric slider 10 downward to rotate the burr grinding wheel 14 until the upper end surface of the burr grinding wheel 14 is in contact with the upper end surface of the stainless steel plate 5. As the rotating burr-grinding wheel 14 moves downward, the electric ring 6 ensures that the burr-grinding wheel 14 is always positioned behind the tangent of the cutting path, and the electric slider 9 controls the distance between the burr-grinding wheel 14 and the laser cutting head 15 to adapt to the distance changes at the corner and ensure that the burr-grinding wheel 14 can always move along the moving path of the laser cutting head 15. When the rotating burr-removing grinding wheel 14 moves along the moving path of the laser cutting head 15, the burrs on the stainless steel plate 5 can be removed by the rotating burr-removing grinding wheel 14. The above technical solution enables the simultaneous grinding of burrs during the cutting process, thereby improving the efficiency of stainless steel product production.
