Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel plate cutting technology, and in particular relates to a laser cutting device for steel plate cutting. Background Technology
[0002] As modern manufacturing continues to develop towards higher precision and efficiency, higher demands are being placed on the quality and efficiency of steel plate cutting processes. Laser cutting technology, with its advantages of high cutting speed, good cut quality, and wide adaptability, has become a core process in sheet metal processing. In steel plate cutting operations, large, solid plates often need to be precisely cut into strips of specific widths to meet the dimensional requirements of downstream processes or final products.
[0003] Currently, laser cutting equipment typically uses an array of support pins on the cutting platform. These pins lift and stabilize the steel plate, maintaining a proper gap between the steel plate and the cutting platform surface, allowing the laser cutting head assembly to smoothly and precisely cut the steel plate into strips. However, most existing laser cutting equipment uses fixed support pins, which are difficult to disassemble. During long-term cutting operations, molten slag and metal spatter generated by laser melting easily accumulate in the gaps between the support pins and on the surface of the cutting platform, gradually forming stubborn deposits. Since the laser cutting head assembly and its moving mechanisms, such as the crossbeam and slide rails, span across the cutting platform, they severely compress the operating space below, making manual or mechanical cleaning extremely difficult, increasing maintenance costs and downtime.
[0004] Therefore, there is a particular need for a laser cutting device for steel plates to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of existing laser cutting equipment, such as the fixed structure of the support pin, which is difficult to disassemble, resulting in difficult cleaning after slag accumulation, high maintenance costs, and long downtime, this utility model provides a laser cutting equipment for steel plate cutting.
[0006] This utility model is achieved through the following technical means: A laser cutting device for steel plate cutting includes a mounting base, a support pin plate, a longitudinal electric slide rail, an electric slider one, a mounting plate, a vertical electric slide rail, an electric slider two, a horizontal electric slide rail, an electric slider three, a laser cutting head assembly, and a controller. The support pin plate is placed on the upper part of the mounting base. Longitudinal electric slide rails are installed on both sides of the upper part of the mounting base. An electric slider one is slidably arranged on each longitudinal electric slide rail. An mounting plate is installed on each electric slider one. Vertical electric slide rails are installed on the side of the two mounting plates that are close to each other. An electric slider two is slidably arranged on each vertical electric slide rail. A horizontal electric slide rail is installed between two electric slider twos. An electric slider three is slidably arranged on the horizontal electric slide rail. A laser cutting head assembly is installed on the electric slider three. A controller is installed on one side of the front part of the mounting base. The longitudinal electric slide rail, electric slider one, vertical electric slide rail, electric slider two, horizontal electric slide rail, electric slider three, and laser cutting head assembly are all electrically connected to the controller.
[0007] Further explanation: The mounting base is equipped with a locking assembly, which includes guide rods, a locking plate, a sliding plate, a screw, a worm gear, a worm, and a rotating wheel. Guide rods are fixedly connected to one side of the front and both sides of the rear of the mounting base. A sliding plate is slidably arranged between multiple guide rods. Multiple locking plates are fixedly connected to the top of the sliding plate and are distributed longitudinally at equal intervals. The locking plates pass through the mounting base and are inserted into the support pin plate. A screw is rotatably arranged on the other side of the front of the mounting base. The screw passes through the sliding plate and is threadedly engaged with the sliding plate. A worm gear is fixedly connected to one end of the screw. A worm is also rotatably arranged on the other side of the front of the mounting base. The worm is located behind the worm gear and meshes with the worm gear. A rotating wheel is fixedly connected to one end of the worm.
[0008] To further clarify, the support pin plate can only slide back and forth along the mounting base.
[0009] To further clarify, the controller is a programmable logic controller.
[0010] To further explain, the length of the sliding plate matches the length of the support needle plate.
[0011] To further clarify, the guide rod and the screw rod are at the same height.
[0012] Beneficial effects: This utility model, by setting a detachable support needle plate and cooperating with a locking assembly composed of a rotating wheel, worm, worm gear, screw, sliding plate and clamping plate, realizes quick locking and convenient disassembly of the support needle plate, which facilitates the cleaning of molten slag and spatter in the gap between the needles of the support needle plate and significantly improves maintenance efficiency.

[0019] Example: A laser cutting device for cutting steel plates, such as... Figures 1-5 As shown, the assembly includes a mounting base 1, a support pin plate 2, a longitudinal electric slide rail 3, an electric slider 4, a mounting plate 5, a vertical electric slide rail 6, an electric slider 7, a transverse electric slide rail 8, an electric slider 9, a laser cutting head assembly 10, and a controller 11. The support pin plate 2 is placed on the upper part of the mounting base 1. The support pin plate 2 can only slide back and forth along the mounting base 1. Because the lower part of the support pin plate 2 slides into the upper part of the mounting base 1, and the left and right side walls of the support pin plate 2 maintain sliding contact with the mounting base 1, the left and right sliding direction of the support pin plate 2 is restricted, allowing it to slide only back and forth along the mounting base 1, thus limiting the displacement of the support pin plate 2 in the left and right directions. The upper left and right sides of the mounting base 1 are respectively connected to the longitudinal electric slide rails 3 by bolts. Each longitudinal electric slide rail 3 is slidably mounted with an electric slider 4. Each electric slider 4 is bolted to a mounting plate 5. Vertical electric slide rails 6 are bolted to the sides of two mounting plates 5 that are close to each other. Electric sliders 7 slide on each vertical electric slide rail 6. A horizontal electric slide rail 8 is bolted between two electric sliders 7. Electric sliders 9 slide on the horizontal electric slide rail 8. A laser cutting head assembly 10 is bolted to electric slider 9. A controller 11 is bolted to the front left side of the mounting base 1. The vertical electric slide rails 3, electric sliders 4, vertical electric slide rails 6, electric sliders 7, horizontal electric slide rails 8, electric sliders 9, and laser cutting head assembly 10 are all electrically connected to the controller 11. The controller 11 is a programmable logic controller, model Huichuan Easy 521-24T4DT.
[0020] like Figures 1-5 As shown, the mounting base 1 is equipped with a locking assembly, which includes a guide rod 12, a locking plate 13, a sliding plate 14, a screw 15, a worm gear 16, a worm 17, and a rotating wheel 18. Guide rods 12 are fixedly connected to the front left side and the rear left and right sides of the mounting base 1. A sliding plate 14 is slidably arranged between the three guide rods 12. The length of the sliding plate 14 matches the length of the support pin plate 2. Multiple locking plates 13, arranged longitudinally and equidistantly, are fixedly connected to the top of the sliding plate 14. The locking plates 13 pass through the mounting base 1 and are inserted into the support pin plate 2, thereby securing the mounting base. The position of the support needle plate 2 on the mounting base 1 is fixed to prevent the support needle plate 2 from slipping. A screw 15 is rotatably installed on the front right side of the mounting base 1. The screw 15 passes through the sliding plate 14 and is threadedly engaged with the sliding plate 14. The guide rod 12 is at the same height as the screw 15. A worm wheel 16 is fixedly connected to the upper end of the screw 15. A worm 17 is also rotatably installed on the front right side of the mounting base 1. The worm 17 is located behind the worm wheel 16 and meshes with the worm wheel 16. A rotating wheel 18 is fixedly connected to the right end of the worm 17, which allows the operator to apply force to rotate the worm 17.
[0021] When this equipment is needed for steel plate cutting, the operator first places the steel plate to be cut into strips stably on the support needle plate 2. After placement, the controller 11 calls the pre-set cutting program. Before the program officially runs, the controller 11 performs a self-check. After the self-check passes, the controller 11 synchronously controls the longitudinal electric slide rail 3, the vertical electric slide rail 6, and the transverse electric slide rail 8. Electric slider 1 4 slides along the longitudinal electric slide rail 3 according to the preset trajectory, electric slider 2 7 slides along the vertical electric slide rail 6 according to the preset trajectory, and electric slider 3 9 slides along the transverse electric slide rail 8 according to the preset trajectory. Under the three-axis linkage, the laser cutting head assembly 10 can be precisely positioned in space and emit a high-energy laser beam according to the preset trajectory to cut the steel plate into the required strip structure. The slag and spatter generated during the cutting process mainly fall into the gap between the needles of the support needle plate 2. After the cutting is completed, the laser cutting head assembly 10 moves along the electric slider 1 4, electric slider 2 7, and transverse electric slide rail 8. Driven by the second 7 and the electric slider 39, the steel bar returns to its initial position, allowing the operator to remove the cut steel strip. When cleaning the support pin plate 2 is required, the worm gear 17 is rotated clockwise via the rotating wheel 18 (viewed from the right side of the mounting base 1). As the worm gear 17 rotates, it meshes with the worm wheel 16, driving the worm wheel 16 to drive the screw 15 to rotate counterclockwise (viewed from the top of the sliding plate 14). Driven by the screw 15, the sliding plate 14 moves the locking plate 13 downward, disengaging the locking plate 13 from the support pin plate 2, thus releasing the lock on the support pin plate 2. At this time, the support pin plate 2 can be smoothly pulled out along the front and back direction of the mounting base 1 for easy cleaning. After cleaning, the support pin plate 2 is pushed back onto the mounting base 1, and the worm gear 17 is rotated counterclockwise again, driving the worm wheel 16 to drive the screw 15 to rotate clockwise, driving the sliding plate 14 to move the locking plate 13 upward. The locking plate 13 is then reinserted into the support pin plate 2, achieving reliable locking.
