Description

Technical Field

[0001] The present application relates to the field of laser cutting technology, and in particular to a slag removal structure for a laser cutting bed. Background Art

[0002] Laser cutting machines use a high-energy laser beam to irradiate the workpiece, causing the irradiated surface to heat up rapidly and become molten. Auxiliary gas is then used to blow away the slag, achieving the desired cutting effect. However, during this process, some of the slag solidifies on the laser cutting machine's serrated worktable, affecting its proper operation. Currently, there's no effective way to quickly clean this slag, requiring a rack slag remover to move along the serrated grid plate to remove the slag from the worktable.

[0003] However, in actual operation, workers need to manually operate the rack slag remover to clean along each serrated grid plate, and can only clean a single serrated grid plate at a time, resulting in low cleaning efficiency and long working time. Utility Model Content

The lower ends of the fixed tool holder and the movable tool holder are detachably provided with scrapers for removing slag on the serrated grid plate.

[0008] Preferably, the serrated grid plate is located on the inner side of the corresponding two scrapers, and slag removal teeth are provided on the side of the scraper close to the serrated grid plate.

[0009] Preferably, a guide rod is provided on the inner side of the bracket, the guide rod passes through the movable knife holder and is slidably connected to the movable knife holder, and the fixed knife holder is fixedly sleeved on the guide rod.

A three-axis feeding system 7 is also installed on the workbench 1. The movable end of the three-axis feeding system 7 is connected to a laser cutting head 3. A multi-point support plane is formed by the serrated grid plates 2 to support the workpiece. The position of the laser cutting head 3 is adjusted by the three-axis feeding system 7 to achieve laser cutting at different positions.

[0020] Reference Figure 2 A gantry 4 is installed on the workbench 1, and a single-axis feeding system 8 is also installed on the workbench 1. For example, the single-axis feeding system 8 adopts a single-axis servo feeding system with a ball screw, including a screw rod 803 rotatably installed on the lower side of the workbench 1, the screw rod 803 is connected to an external servo motor, and a slide 802 is installed on the screw rod 803 for transmission. Two guide rails 801 are installed on the X-axis direction of the workbench 1, and the slide 802 is slidably installed on the two guide rails 801. The gantry 4 is installed on the slide 802, and the screw rod 803 is driven to rotate by the servo motor, thereby driving the slide 802 to move back and forth along the X-axis to realize the reciprocating movement of the gantry 4 along the X-axis.

[0021] Reference Figure 2 A reciprocating assembly 5 is installed on the gantry 4, and the reciprocating assembly 5 includes a rotating shaft 501. Both ends of the rotating shaft 501 are equipped with a crank-connecting rod mechanism. The crank-connecting rod mechanism includes a connecting rod 502 rotatably mounted on the rotating shaft 501, and the end of the connecting rod 502 is hinged with a rotating plate 503, one of the rotating plates 503 is connected to a driving motor 504 through a gearbox transmission, and the other rotating plate 503 is rotatably installed with a support plate, and the support plate is fixedly connected to the gantry 4. A pull rod 505 is rotatably provided on the rotating shaft 501, and the lower end of the pull rod 505 passes through the gantry 4 and is connected to the cleaning assembly 6. The rotating plate 503 is driven to rotate by the driving motor 504, so that the connecting rod 502 drives the rotating shaft 501 to move up and down, thereby pulling the pull rod 505 and the cleaning assembly 6 to move back and forth along the Z axis.

[0022] Reference Figure 3The cleaning assembly 6 includes a bracket 601 installed at the lower end of the pull rod 505, a guide rod 602 is installed on the inner side of the bracket 601, and a plurality of fixed knife seats 603 and movable knife seats 604 are sleeved on the guide rod 602, wherein the fixed knife seat 603 is fixedly sleeved on the guide rod 602, and the movable knife seat 604 is slidably sleeved on the guide rod 602, and the fixed knife seat 603 and the movable knife seat 604 are staggered. The lower ends of the fixed knife seat 603 and the movable knife seat 604 are detachably mounted with a scraper 605, such as through Bolt installation, an adjusting screw 606 is rotatably installed on the bracket 601, the end of the adjusting screw 606 passes through the movable knife seat 604 and is threadedly connected to the movable knife seat 604, and the movable knife seat 604 is driven close to the fixed knife seat 603 by rotating the scraper 605, so that the scraper 605 is close to the serrated grid plate 2, and the distance between the two pairs of scrapers 605 is adjusted. The serrated grid plate 2 is located on the inner side of the corresponding two scrapers 605, and a slag removal tooth is installed on the side of the scraper 605 close to the serrated grid plate 2.

[0023] The implementation principle of the slag removal structure of a laser cutting bed in the embodiment of the present application is as follows:

[0024] The workpiece to be cut is placed on the workbench 1. The laser cutting head 3 is initially positioned using the three-axis feed system 7, preparing for the laser cutting operation. The three-axis feed system 7 adjusts the position of the laser cutting head 3 in the X, Y, and Z directions according to the cutting requirements to achieve precise cutting. During the laser cutting process, slag may be generated on the workpiece surface, which must be cleaned promptly to ensure cutting quality and efficiency.

[0025] By rotating the scraper 605, the movable knife holder 604 is driven to approach the fixed knife holder 603, so that the scraper 605 is close to the serrated grid plate 2, and the distance between the two pairs of scrapers 605 is adjusted so that the scrapers 605 are clamped on both sides of the serrated grid plate 2. During cleaning, the gantry 4 is driven to move back and forth along the X-axis direction by the single-axis feeding system 8, driving the entire cleaning assembly 6 to move above the workpiece. At the same time, the rotating plate 503 is driven to rotate by the drive motor 504, so that the connecting rod 502 drives the rotating shaft 501 to move up and down, and then pulls the pull rod 505 and the cleaning assembly 6 to move back and forth along the Z-axis, realizing the reciprocating movement of the cleaning assembly 6 in the Z-axis direction. This reciprocating motion enables the cleaning assembly to approach and clean the slag on the surface of the workpiece. With the continuous movement of the gantry 4 and the cleaning assembly 6, the slag on the surface of the workpiece is gradually cleaned.

[0026] After cleaning is completed, the slag cleaned up can be further collected and processed by other means such as a dust collection device. The cleaning assembly 6 and the gantry 4 return to their initial positions, ready for the next round of cutting and cleaning operations.
