Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a conveyable steel strip laser cutting equipment and method. Background Art

[0002] Steel strip is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Generally, the steel strip is rolled into a coil for easy transportation. However, in the further processing of the steel strip, it is necessary to cut the steel strip according to the needs. Laser cutting equipment is generally used for cutting steel strip.

[0003] For example, a metal sheet laser cutting device proposed in the existing authorization announcement No. CN118768765B includes a mobile cutting mechanism, a protrusion processing mechanism, a supporting and flipping feeding mechanism, a shaking mechanism, etc. The device installs a supporting and flipping feeding mechanism to flip the supporting part so that the workpiece hanging on the spikes automatically falls off. The shaking mechanism shakes the supporting part to make the workpiece that cannot be removed due to metal slag fall off, thereby solving the problem of material jamming during feeding.

[0004] Although the equipment can prevent metal slag from sticking to the steel plate, the equipment still needs to be manually placed to place the steel plate when in use, and the steel plate needs to be removed after cutting is completed, and automatic loading and unloading cannot be achieved.

After the steel sheets fall in, the four fourth electric cylinders 903 synchronously push the guide plates 908 to move, center the steel sheets, and thus achieve flat stacking of the steel sheets. When the tension sensor 910 detects that the steel sheets are stacked to a certain weight, the fifth electric cylinder 909 drives the conveyor belt 907 to move downward, so that the stacked steel sheets extend from under the space formed by the guide plates 908, and then are transported by the conveyor belt 907 to send out the stacked steel sheets. When the position of the hollow bar 904 needs to be adjusted, the second locking knob 901 can be loosened, and then the hollow bar 904 can be slid for adjustment.

[0046] The working principle of the present invention is as follows: when in use, the steel belt enters from the gap of the guide roller 3, and the limit mechanism 4 is provided to limit the steel belt to prevent the steel belt from deviating during movement. When the steel belt is pulled, the linear module 604 drives the transverse plate 601 to move toward the steel belt.

The steel belt is clamped by the cooperation of the lower clamping plate 605 and the upper clamping plate 603, and then the linear module 604 drives the transverse plate 601 to move toward the limit switch 811, and stops after touching the limit switch 811, thereby realizing The steel strip is now pulled at a fixed distance, and then the third electric cylinder 708 is actuated to drive the clamping plate 709 to move. The clamping plate 709 cooperates with the connecting plate 710 to fix the steel strip to prevent the steel strip from moving during the cutting process. Then the second electric cylinder 702 drives the mounting slot block 704 to descend so that the laser cutting head 705 descends to the cutting position. When the mounting slot block 704 moves downward, it drives the rack 801 to move downward. The downward movement of the rack 801 drives the gear 802 to rotate. The rotation of the gear 802 drives the end shaft 806. Then, under the action of the hexagonal sleeve shaft 803, the hexagonal shaft 804 and the first bevel gear 805, the two second bevel gears are The wheel 807 rotates synchronously, and then the U-shaped support frame 808 can be driven to flip. After the two U-shaped support frames 808 flip to the upper side, they form a support to support the cut steel strip. At the same time, the output end of the first electric cylinder 606 contracts to drive the lower clamping plate 605 to open, and then the servo motor 711 drives the screw rod 703 to rotate, and the rotation of the screw rod 703 drives the laser cutting head 705 to move. The laser cutting head 705 emits a high-energy laser beam to cut the steel strip. After the cutting is completed, the rack 801 moves up to drive the gear 802 to rotate accordingly, thereby driving the U-shaped support frame 808 to flip downward, so that the cut steel sheet can be released. The fourth electric cylinder 903 can drive the guide plate 908 to move. Before the steel sheet falls, the fourth electric cylinder 903 is in a retracted state. At this time, the space formed by the guide plate 908 becomes larger, so that the steel sheet can fall in smoothly. After the steel sheet falls in, the four fourth electric cylinders 903 synchronously push the guide plate 908 to move, center the steel sheet, and then achieve flat stacking of the steel sheets. When the tension sensor 910 detects that the steel sheets are stacked to a certain weight, the fifth electric cylinder 909 drives the conveyor belt 907 to move downward, so that the stacked steel sheets extend from under the space formed by the guide plate 908, and then are transported by the conveyor belt 907 to send the stacked steel sheets out.

10. A method for using the conveyable steel strip laser cutting device according to claim 9, characterized in that: The steps include: Step 1. When in use, the steel belt enters from the gap of the guide roller (3). The limit mechanism (4) is used to limit the steel belt to prevent the steel belt from deviating during movement. When the steel belt is pulled, the linear module (604) drives the transverse plate (601) to move toward the steel belt. After moving to the position of the steel belt, the first electric cylinder (606) drives the driving arm (607). The driving arm (607) drives the lower clamping plate (605) to move. The steel belt is clamped by the cooperation of the lower clamping plate (605) and the upper clamping plate (603). Then the linear module (604) drives the transverse plate (601) to move toward the limit switch (811) and stops after touching the limit switch (811), thereby realizing the fixed distance traction of the steel belt. Step 2, the third electric cylinder (708) then drives the clamping plate (709) to move, and the clamping plate (709) cooperates with the connecting plate (710) to fix the steel strip to prevent the steel strip from moving during the cutting process, and then the second electric cylinder (702) drives the mounting slot block (704) to descend so that the laser cutting head (705) descends to the cutting position, and when the mounting slot block (704) moves downward, it drives the rack (801) to move downward, and the rack (801) moves downward to drive the gear (802) to rotate, and the rotation of the gear (802) drives the end shaft (806), and then on the hexagonal sleeve shaft ( 803), the hexagonal shaft (804) and the first bevel gear (805) cause the two second bevel gears (807) to rotate synchronously, thereby driving the U-shaped support frame (808) to flip over. After the two U-shaped support frames (808) flip to the upper side, they form a support to support the cut steel strip. At the same time, the output end of the first electric cylinder (606) contracts to drive the lower clamping plate (605) to open, and then the servo motor (711) drives the screw rod (703) to rotate. The rotation of the screw rod (703) drives the laser cutting head (705) to move, and the laser cutting head (705) emits a high-energy laser beam to cut the steel strip. Step 3: After the cutting is completed, the rack (801) moves upward to drive the gear (802) to rotate accordingly, thereby driving the U-shaped support frame (808) to flip downward, thereby releasing the cut steel sheet. At the same time, the fourth electric cylinder (903) can drive the guide plate (908) to move. Before the steel sheet falls, the fourth electric cylinder (903) is in a contracted state. At this time, the space formed by the guide plate (908) becomes larger, allowing the steel sheet to fall in smoothly. After the steel sheet falls in, the four fourth electric cylinders (903) synchronously push the guide plate (908) to move, centering the steel sheet, thereby achieving flat stacking of the steel sheets. When the tension sensor (910) detects that the steel sheets are stacked to a certain weight, the fifth electric cylinder (909) drives the conveyor belt (907) to move downward, so that the stacked steel sheets extend from below the space formed by the guide plate (908), and then are transported by the conveyor belt (907) to send the stacked steel sheets out.
