Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and in particular to a flatbed laser cutting machine for processing iron tower parts. Background Technology

[0002] As the core load-bearing structure of power transmission networks, transmission towers serve in complex outdoor environments for extended periods, demanding extremely high strength, dimensional accuracy, and stability from their components. During operation and maintenance, towers frequently suffer localized damage due to corrosion, collisions, and natural disasters, requiring rapid replacement and repair with replacement parts. These replacement parts are mostly high-strength thick steel plates, characterized by varied specifications, small batches, thick plates, numerous irregular shapes, and high assembly precision requirements. Currently, tower replacement part processing is gradually transitioning from traditional flame cutting and plasma cutting to laser cutting. Laser cutting offers advantages such as narrow kerfs, small heat-affected zones, high precision, and good cross-sectional quality, effectively meeting the high-precision cutting requirements of tower components. Simultaneously, the industry is promoting intelligent manufacturing upgrades, with some companies having built intelligent heat treatment production lines. Through automated loading and unloading, intelligent temperature control, and stress homogenization treatment, residual stress after tower component cutting is precisely eliminated, significantly reducing subsequent deformation and improving component dimensional stability and fatigue life. To this end, patent CN117921212B discloses a laser cutting device, mainly comprising: a base; a cutting assembly mounted on the upper end of the base; a supporting mechanism disposed on one side of the cutting assembly for placing the metal plate to be cut, the supporting mechanism having: a frame mounted on the upper end of the base; a crossbeam mounted on the inner side of the frame; a support hand mounted on the crossbeam for supporting the metal plate to be cut; a scraping mechanism disposed on the side of the support hand, the scraping mechanism having: a first mounting seat; a second mounting seat, the first and second mounting seats located on both sides of the support hand; a scraper mounted on the upper end of the first and second mounting seats; and an adjusting assembly disposed at both ends of the first and second mounting seats. This laser cutting device prevents residue generated during cutting from adhering to both sides of the support hand, allowing the metal plate to be placed stably on the support hand. The existing technical solutions mentioned above have the following defects: When in use, it is impossible to clean the slag on each support grid in a stable and continuous manner. As a result, during the laser cutting operation of the iron tower thick plate parts, a large amount of high-temperature slag and metal debris will continue to accumulate and get stuck on the grid surface. Long-term slag accumulation will directly cause the worktable support surface to be uneven. When the thick steel plate to be processed is placed, it cannot maintain a horizontal and close fit. The problems of local suspension and uneven force are prominent, which greatly aggravates the thermal warping and torsional deformation during the thick plate cutting process, and seriously affects the dimensional accuracy, hole accuracy and cut flatness of the iron tower parts. Summary of the Invention

The T-shaped guide block is symmetrically arranged about the central axis of the support frame. The guide plate is fixedly installed on the top of the laser cutting machine body.

[0006] Preferably, the cam forms a rotating structure with the L-shaped bracket via a rotating rod, the transmission chuck forms a sliding structure with the guide plate via an avoidance groove, and the arc-shaped plate is movably connected to the guide plate via an arc-shaped groove.

[0007] Preferably, a half gear is fixedly connected to one end of the rotating rod, a rack is movably connected to the outer wall of the half gear, a receiving plate is fixedly connected to the outer wall of the rack, a receiving rod is fixedly connected to the bottom of the receiving plate, a return spring is sleeved on the outer wall of the receiving rod, a cleaning scraper is fixedly connected to the bottom end of the receiving rod, an auxiliary scraper is movably connected to the inner wall of the cleaning scraper, and a support rod is fixedly connected to the top of the auxiliary scraper.

[0008] Preferably, the half gear is connected to the support frame via a rotating rod to form a rotating structure, and the half gear is meshed with a rack.

[0009] Preferably, the receiving rod and the support frame form a sliding structure, the receiving rod is symmetrically arranged about the central axis of the cleaning scraper, the cleaning scraper and the auxiliary scraper form a sliding structure, and the top end of the support rod is fixedly connected to the support frame.

[0010] Preferably, a movable rod is fixedly connected to one side of the receiving plate, a piston is fixedly connected to one end of the movable rod, an air cylinder is movably connected to the outer wall of the piston, an air outlet valve is installed on the outer wall of the air cylinder, an air supply pipe is fixedly connected to the output end of the air outlet valve, a nozzle is installed on the outer wall of the support frame, an air inlet valve is installed on the outer wall of the air cylinder, and an air inlet pipe is fixedly connected to the input end of the air inlet valve.

[0011] Preferably, the piston and the air cylinder form a sliding structure, and the nozzles are evenly distributed on the outer wall of the support frame.

[0012] Preferably, a Y-axis movable frame is movably connected to the outer wall of the laser cutting machine body, an X-axis movable frame is movably connected to the outer wall of the Y-axis movable frame, a laser cutting assembly is movably connected to the outer wall of the X-axis movable frame, a protective mechanism is installed at the bottom of the laser cutting assembly, the protective mechanism includes a positioning ring fixedly installed at the bottom of the laser cutting assembly, a threaded groove is opened inside the positioning ring, a threaded column is movably connected inside the positioning ring, a protective cover is fixedly connected to the bottom of the threaded column, a sleeve block is fixedly connected to the outer wall of the protective cover, a movable groove is opened inside the sleeve block, and a ball is movably connected inside the movable groove.

[0013] Preferably, the positioning ring is threadedly connected to the threaded column through a threaded groove, and the ball bearing is connected to the sleeve block through a movable groove to form a rotating structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: When the flatbed laser cutting machine for processing tower parts is in use, starting the drive motor causes the half-gear fixedly connected to one end of the rotating rod to rotate, causing the cleaning scraper fixedly connected to the bottom end of the receiving rod to slide down along the support grid, facilitating the scraping and cleaning of molten slag on the support grid. With the cooperation of the transmission lever and the clearance groove, the cleaning scraper can move to the top of the next support grid, achieving continuous molten slag removal processing of the support grid. Furthermore, with the assistance of the nozzle to blow air, the molten slag is blown into the collection tank inside the laser cutting machine body, improving the efficiency of cleaning molten slag on the support grid and preventing molten slag accumulation from affecting the stability of the support grid. The specific method is as follows: By setting up a support grid and a cleaning mechanism, starting the drive motor can rotate the half gear fixedly connected to one end of the rotating rod, causing the support plate fixedly connected to the outer wall of the rack to move down and squeeze the return spring. This causes the cleaning scraper fixedly connected to the bottom end of the support rod to slide down along the support grid, which facilitates the scraping and cleaning of molten slag on the support grid. Moreover, a single downward movement can complete the cleaning of the entire support grid, improving the efficiency of cleaning molten slag on the support grid and preventing the stability of the support grid from being affected by the accumulation of molten slag. Furthermore, when the cleaning scraper rises and resets, it slides along the auxiliary scraper, allowing any slag accidentally adhering to the inner wall of the cleaning scraper to be scraped off by the auxiliary scraper, thus avoiding the need for manual cleaning of the cleaning scraper and further improving the efficiency of slag removal. Furthermore, as the cam continues to rotate, it drives the transmission lever to move into the clearance groove inside the guide plate, thereby driving the support frame to move as a whole, so that the cleaning scraper moves to the top of the next support grid, realizing continuous slag removal processing of the support grid, improving the continuity of cleaning processing, and further improving the efficiency of cleaning the slag attached to the support grid. Furthermore, as the receiving plate moves down, it drives the piston, which is fixedly connected to one end of the movable rod, to slide along the air cylinder, compressing the air inside the air cylinder. The compressed air is then transported to the nozzle through the air supply pipe and discharged. This causes the molten slag on the support grid to be scraped off by the cleaning scraper and blown down into the collection tank inside the laser cutting machine body by the nozzle, preventing molten slag from splashing and further improving the efficiency of cleaning the molten slag on the support grid. By incorporating a protective mechanism, the threaded column is aligned with the inner bottom wall of the positioning ring and rotated through a movable protective cover. This allows the protective cover to be fitted onto the outer wall of the laser welding head, effectively blocking and protecting against sparks generated by laser cutting. The ball bearings also prevent the protective cover from rubbing against the steel plate component. Attached Figure Description

An arc-shaped plate 48 is fixedly connected to one side of the cam 46. A guide plate 49 is movably connected to the outer wall of the arc-shaped plate 48. The guide plate 49 has a clearance groove 491 and an arc-shaped groove 492 inside. The distance between the two clearance grooves 491 is the same as the distance between the two support grates 2. The T-shaped guide block 42 forms a sliding structure with the laser cutting machine body 1 through the T-shaped guide groove 3. The T-shaped guide block 42 is symmetrically arranged about the central axis of the support frame 41. The guide plate 49 is fixedly installed on the top of the laser cutting machine body 1. The support grates 2 are connected to the laser cutting machine body 1. The inner wall is evenly spaced. Cam 46 forms a rotating structure with L-shaped bracket 43 via rotating rod 45. Transmission rod 47 forms a sliding structure with guide plate 49 via clearance groove 491. Arc plate 48 is movably connected to guide plate 49 via arc groove 492.

The cleaning scraper 456 has an open design, and the cleaning scraper 456 and the support rod 458 form a sliding structure.

[0020] By starting the drive motor 44, the half gear 451, which is fixedly connected to one end of the rotating rod 45, can rotate. Since the half gear 451 meshes with the rack 452, the rack 452 can slide downwards along the support frame 41, causing the receiving plate 453, which is fixedly connected to the outer wall of the rack 452, to move downwards and compress the return spring 455. This causes the cleaning scraper 456, which is fixedly connected to the bottom end of the receiving rod 454, to slide downwards along the support scabbard 2, thereby scraping away and cleaning the slag on the support scabbard 2. When the cleaning scraper 456 rises to its reset position, it slides along the auxiliary scraper 457, causing the inner wall of the cleaning scraper 456 to... The external slag is scraped off. After the half gear 451 and rack 452 disengage, the cleaning scraper 456 can be raised and reset under the action of the return spring 455. During this period, the arc plate 48 fixedly connected to the outer wall of the cam 46 slides along the arc groove 492. As the cam 46 continues to rotate, it drives the transmission lever 47 to move into the clearance groove 491 opened inside the guide plate 49, thereby driving the support frame 41 to move as a whole. The T-shaped guide block 42 slides along the T-shaped guide groove 3, so that the cleaning scraper 456 moves to the top of the next support sword grid 2, realizing continuous slag removal processing of the support sword grid 2.

The piston 4532 and the air cylinder 4533 form a sliding structure. The nozzles 4536 are evenly distributed on the outer wall of the support frame 41.

[0022] As the receiving plate 453 moves down, it drives the piston 4532, which is fixedly connected to one end of the movable rod 4531, to slide along the air cylinder 4533, compressing the air inside the air cylinder 4533. At this time, the air outlet valve 4534 opens and the air inlet valve 4537 closes. The compressed air is delivered to the nozzle 4536 through the air supply pipe 4535 and discharged. The molten slag on the support sword grid 2 is scraped off by the cleaning scraper 456 and blown down into the collection tank inside the laser cutting machine body 1 through the nozzle 4536. When the receiving plate 453 rises and resets, it drives the piston 4532 to slide up along the air cylinder 4533.
