Description

Technical Field

[0001] This invention relates to the field of laser cutting technology for steel plates, specifically to a laser precision segmentation device applied to steel plate processing. Background Technology

[0002] Laser cutting is a thermal cutting method that uses a high-power-density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize, ablate, or reach its ignition point. At the same time, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece apart.

[0003] In the laser cutting process of steel plates, a support table is usually required to support the steel plate. Currently, the industry commonly uses a toothed support array as the load-bearing structure. This means that multiple sets of sharp support teeth are arranged in a matrix to form a support table. The steel plate is placed directly on the top of the support teeth to reduce the contact area, avoid laser damage to the table, and facilitate the falling of molten slag. The high-temperature molten slag generated by laser cutting splashes directly and sintersects on the top of the support teeth. After cooling, it forms hard residue, causing the support teeth to be uneven and reducing the support accuracy. This, in turn, affects the dimensional accuracy and cut quality of the steel plate. At the same time, the corrugated structure of the teeth makes it difficult to clean the residue on the teeth afterward.

[0004] Therefore, we propose a laser precision segmentation device for steel plate processing to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a laser precision segmentation device for steel plate processing. It solves the problems mentioned in the background technology, where high-temperature molten slag generated by laser cutting directly splashes and sintersects on the top of the support teeth, forming hard residue after cooling. This causes uneven support teeth, reduced support accuracy, and consequently affects the dimensional accuracy and cut quality of the steel plate. Furthermore, the corrugated structure of the teeth makes it difficult to clean the residue on the teeth afterward.

[0006] (II) Technical Solution To achieve the above objectives, the present invention specifically adopts the following technical solution: A laser precision segmentation device for steel plate processing includes a laser cutting host, a movable gantry mounted on the laser cutting host, a laser cutting head for cutting steel plates mounted on the movable gantry, and steel plate support teeth mounted inside the laser cutting host, with an embedded column connected to the side end of a rotating connecting block. The functional side plate is reinforced to the surface of the laser cutting host by bolts. The actuating rod is installed on one side of the functional side plate. The side end of the actuating rod passes through the functional side plate and is connected to the embedded column. The other side end of the actuating rod extends upward to have an actuating top protrusion. Below the mobile gantry is a base plate that moves synchronously with the mobile gantry and is used to actuate the top protrusion to rotate the actuating linkage.

[0007] Furthermore, a residue recovery tank is installed on the inner side of the laser cutting host and below the steel plate support teeth, and a discharge port communicating with the internal cavity of the residue recovery tank is provided on the side of the laser cutting host.

[0008] Furthermore, the surface of the functional side plate is provided with insertion holes, and bearing assemblies are embedded in the insertion holes. Synchronous shafts extending to both sides are assembled in the bearing assemblies.

[0009] Furthermore, a docking plate is fixedly provided at one end of the synchronous shaft, and a docking groove plate for inserting the embedded column into the groove is fixedly provided on the side of the docking plate; The surfaces of the mating groove plate and the embedded column are provided with corresponding mating holes, and a U-shaped connector with a double-threaded structure is inserted into the groove of the mating hole; The bottom of the rotating connecting block is fixed with an arc-shaped support block, and the bottom of the arc-shaped support block is attached to a long support plate. The two ends of the long support plate are reinforced to the surface of the laser cutting host by bolts.

[0010] Furthermore, a rotating connecting block is fixed at the other end of the synchronous shaft, and the side of the rotating connecting block is fixed to the side end of the actuating linkage.

[0011] Furthermore, two sets of protruding plates are symmetrically fixed on the side of the rotating connecting block. A detachable arc-shaped spring is installed on the protruding plate. A low horizontal plate located directly below the center of the rotating connecting block is welded to the side of the functional side plate. The other end of the arc-shaped spring is detachably connected to the side of the low horizontal plate.

[0012] Furthermore, a top plate is fixed to the top of the functional side plate, and a plate groove is formed on the surface of the top plate. A slider inside the carrier plate is slidably connected inside the groove of the carrier plate waist. The side of the slider inside the carrier plate is fixed with a downwardly extending actuating plate, and the bottom of the actuating plate is fixedly connected to a guide cone front plate and a guide cone back plate respectively through a connecting support plate.

[0013] Furthermore, the bottom of the movable gantry is reinforced with a functional upright by bolts, and the top of the lever bending rod is bolted to the functional upright. The end of the functional upright is fixed with a horizontal push rod that can touch the inclined surface of the guide cone front plate.

[0014] Furthermore, the two ends of the horizontal push rod are provided with multi-faceted slots, and a synchronous lever that can touch the inclined surface of the guide cone back plate is inserted longitudinally into the multi-faceted slots; The base plate is positioned near the center of the horizontal push rod.

[0015] Furthermore, an arc-shaped guide is provided on one side of the top of the rotating connecting block, so that the bottom horizontal surface of the movable plate slides against the top of the rotating connecting block.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a laser precision segmentation device for steel plate processing, which has the following beneficial effects: This invention features a rotatable steel plate support tooth structure, coupled with a moving gantry frame for linkage drive. When the laser cutting head moves to the corresponding cutting position, the steel plate support tooth can automatically rotate to avoid slag accumulation at the top of the support tooth, significantly reducing the difficulty of slag cleaning. After rotation, the steel plate support tooth is tilted, allowing a small amount of residual slag to slide naturally down the slope into the slag recovery tank, reducing subsequent manual removal, minimizing damage to the support tooth, and extending its service life.

[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Figure 1-9 As shown in the figure, an embodiment of the present invention proposes a laser precision segmentation device for steel plate processing, including a laser cutting host 1, a movable gantry 5 installed on the laser cutting host 1, a laser cutting head 6 for cutting steel plates installed on the movable gantry 5, and steel plate support teeth 4 installed inside the laser cutting host 1. The steel plate support teeth 4 are arranged in a rectangular array inside the laser cutting host 1, and the steel plate to be processed is supported by the steel plate support teeth 4. The device is used in conjunction with a lifting mechanism, which transfers the steel plate to the steel plate support teeth 4. The laser cutting head 6 is moved by the movable gantry 5, and the laser cutting head 6 performs point cutting on the steel plate. Below the steel plate support teeth 4 is a residue recovery tank 2, which is used to collect the waste residue generated by the laser cutting head 6 cutting the steel plate. The amount of residue stored in the residue recovery tank 2 can be observed through the discharge port 3 for cleaning.

[0021] The above structure is the basic design of a common laser cutting device. The power supply and control system will not be described in detail here. The difference lies in the fact that symmetrical functional side plates 7 are provided on both sides of the rectangularly distributed steel plate support teeth 4 inside the laser cutting host 1. These functional side plates 7 are reinforced to the laser cutting host 1 by multiple connecting lugs and bolts. Through holes are formed in the functional side plates 7, located on both sides of a row of steel plate support teeth 4. The row of steel plate support teeth 4 forms a group, and embedded posts 12 are fixedly connected to both ends of the side of each group of steel plate support teeth 4. The bottom of each embedded post 12 is fitted with a mating groove plate 11. The insert column 12 is cylindrical, and the top of the mating groove plate 11 is an arc groove, so that the insert column 12 and the mating groove plate 11 can be combined. At the same time, corresponding mating holes 13 are opened on the surface of the mating groove plate 11 and the insert column 12. U-shaped connectors 14 can be inserted into the grooves of the mating holes 13. After the bolts at both ends of the U-shaped connectors 14 are exposed and nuts are screwed in, the insert column 12 and the mating groove plate 11 can be combined. The mating plate 10 is fixedly connected to the side of the mating groove plate 11, and the synchronous shaft 9 is fixed to the side of the mating plate 10. The synchronous shaft 9 is directly inserted into the through hole opened on the surface of the functional side plate 7. The through hole provides a fulcrum for the synchronous shaft 9, and the bearing assembly 8 can be installed in the through hole, so that the synchronous shaft 9 can rotate and wear less in the through hole.

[0022] A rotating connecting block 18 is fixedly connected to the other end of the synchronous shaft 9, and a connecting lever 19 is fixedly installed on the side of the rotating connecting block 18. An upwardly extending triggering top protrusion 20 is fixed at the end of the lever 19. In actual operation, by turning the triggering top protrusion 20, the entire steel plate support tooth 4 is rotated with the synchronous shaft 9 as the rotation axis. The impurities generated by the laser cutting head 6 when cutting the plate can fall into the side of the steel plate support tooth 4. Since the steel plate support tooth 4 is relatively thin and inclined, most of it falls into the residue recovery tank 2. Although a small part will fall into the side of the steel plate support tooth 4, it will most likely slide out along the inclined surface of the steel plate support tooth 4. Compared with the cutting slag falling directly above the steel plate support tooth 4, the difficulty of cleaning the surface of the steel plate support tooth 4 is greatly reduced, and there is no need to carry out the difficult scraping work in the recessed position of the steel plate support tooth 4.

[0023] In order to complete the above actions and ensure that the steel plate support teeth 4 can rotate into position in advance when the laser cutting head 6 moves to the cutting position, a toggle bending rod 31 that moves synchronously with the mobile gantry 5 is installed below the mobile gantry 5. A plate-mounted toggle base plate 32 is fixed at the bottom of the toggle bending rod 31. That is, as the mobile gantry 5 moves, the toggle base plate 32 moves toward the touch top protrusion rod 20. The surface of the toggle base plate 32 pushes the touch top protrusion rod 20 to rotate around the synchronous shaft 9.

[0024] After the laser cutting head 6 leaves the current welding position, the steel plate support tooth 4 still needs to support the steel plate. Therefore, the synchronous shaft 9 also needs to rotate. Thus, a low horizontal plate 35 is set below the rotating connecting block 18 and welded to the surface of the functional side plate 7. At the same time, a convex plate extending to the side is installed on the side of the rotating connecting block 18, and an arc spring 36 is installed between the low horizontal plate 35 and the convex plate. The hooks at both ends of the arc spring 36 are detachably connected by a hook. When reset is required, the elastic force of the arc spring 36 causes the actuating linkage 19 to return.

[0025] Since the steel plate support tooth 4 has a certain contact force when it contacts the bottom of the steel plate, the elastic force of the arc spring 36 alone cannot guarantee that the steel plate support tooth 4 is in a normal vertical and stable position. Therefore, a set of actuating plates 22 are set above the rotating connecting block 18 so that the bottom of the actuating plates 22 is horizontal. When the steel plate support tooth 4 is in a vertical state, the bottom surface of the actuating plates 22 is in close contact with the top of the rotating connecting block 18. At this time, the rotating connecting block 18 cannot rotate, so that the steel plate support tooth 4 can provide stable support for the steel plate. When the actuating plates 22 move to one side a part and disengage from the rotating connecting block 18, the actuating top protrusion 20 can be rotated. To make the bottom of the steel plate support tooth 4 more stable, an arc-shaped support block 16 with an arc structure is set at the bottom of the steel plate support tooth 4, and the rotation axis of the arc support block 16 is also the synchronous shaft 9. A set of long support plates 17 are assembled at the bottom of the arc support block 16, and the two ends of the long support plates 17 are reinforced on the laser cutting host 1 by bolts, so that the steel plate support tooth 4 is supported by 17.

[0026] To accomplish the above, a set of functional uprights 29 are installed at the bottom of the mobile gantry frame 5 by bolts. The front end of the lever bending rod 31 is bolted to the functional upright 29. A set of long rod-shaped horizontal push rods 30 are fixed at the bottom of the functional upright 29. The guide cone front plate 27 and the guide cone back plate 28 are fixedly connected to the surface of the lever plate 22 by connecting support plates 26, and the guide cone front plate 27 and the guide cone back plate 28 are distributed back to back. The front and rear positions of the horizontal push rod 30 are facing the inclined surface of the guide cone front plate 27. Since the actuating base plate 32 is located near the center of the horizontal push rod 30, before the actuating base plate 32 touches the actuating top protrusion rod 20, the front end of the horizontal push rod 30 first abuts against the guide cone front plate 27, and the actuating vertical plate 22 is moved by pushing the inclined surface of the guide cone front plate 27. The actuating vertical plate 22 will disengage from the top of the rotating connecting block 18. At this time, the rotation restriction of the actuating top protrusion rod 20 is released. The moving gantry 5 can be moved so that the actuating base plate 32 can actuate the actuating top protrusion rod 20 to rotate. Meanwhile, multi-faceted slots 33 are installed at both ends of the horizontal push rod 30. The synchronous lever 34 can be combined with the multi-faceted slot 33. The synchronous lever 34 has a U-shaped structure. After one end of the synchronous lever 34 is inserted into the multi-faceted slot 33, it is locked in the multi-faceted slot 33 with a nut. The other end of the synchronous lever 34 is bent downward and used to contact the inclined surface of the guide cone back plate 28. That is, after the horizontal push rod 30 is separated from the guide cone front plate 27, since the top of the steel plate support tooth 4 may not be able to return to its original position under the pressure of the steel plate, the synchronous lever 34 is pressed against the inclined surface of the guide cone back plate 28 and pushed, so that the bottom of the actuating plate 22 moves towards the top of the rotating connecting block 18. After the synchronous lever 34 finally reaches the end of the inclined surface of the guide cone back plate 28, the bottom surface of the actuating plate 22 will press against the top position of the rotating connecting block 18.

[0027] To make it easier for the actuating plate 22 to move on the rotating connecting block 18, an arc-shaped guide 21 is provided on the top of the rotating connecting block 18. The arc-shaped design of the guide 21 allows the actuating plate 22 to move along the arc surface of the rotating connecting block 18 after the rotating connecting block 18 rotates, thereby improving the quality of the actuating plate 22 pushing the rotating connecting block 18 to rotate and reducing jamming. At the same time, a detachable spring can be installed between the actuating plate 22 and the functional side plate 7 to provide a pre-restoring force for the actuating plate 22. The spring is not shown in the figure.

[0028] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
