Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, specifically to a laser cutting mechanical device for metal material processing. Background Technology

[0002] A laser cutting machine is an industrial device that uses a high-energy laser beam to precisely cut materials. It focuses the laser beam through an optical system, causing the material to melt, vaporize, or reach its ignition point locally and instantaneously. At the same time, an auxiliary gas (such as nitrogen or oxygen) is used to blow away the molten slag, achieving efficient and high-precision cutting.

[0003] Patent CN209936131U discloses a high-precision sheet metal laser cutting machine, including a support plate. Support seats are welded to the bottom of the support plate near the four corners, and support rods are welded to the top of the support plate near the four corners. There are four support rods in total, divided into two groups. Each group has two support rods, and two sliding rods are welded to the top of each rod. A crossbar slides through the outer surface of each sliding rod, and a slider slides through the outer surface of the crossbar. In this invention, pulling the baffle extends the telescopic rod, allowing the baffle to better block the sheet metal. Pulling the U-shaped pull rod moves the cutting plate, allowing the cut sheet metal to fall into the collection frame through the square opening. This reduces the need for workers to remove the cut sheet metal, facilitates stacking, and further reduces the workload of the worker.

[0004] However, the above-mentioned device is difficult to classify workpieces of different sizes after cutting. Therefore, a laser cutting machine for metal material processing is proposed to solve the above-mentioned problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a laser cutting mechanical device for metal material processing, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a laser cutting mechanical device for metal material processing, comprising a machine body, a crossbeam slidably connected to the top of the machine body, a cleaning mechanism provided on the back of the crossbeam, a cutting head provided on the back of the crossbeam, support legs fixedly connected to the bottom of the machine body, a support mechanism provided inside the machine body, and a screening mechanism provided inside the machine body. The support mechanism includes: an upper support bar, a connecting frame, a hydraulic cylinder, a striking rod, a stop block, and a lower support bar. The upper support bar is fixedly connected to the inner wall of the machine body, the connecting frame is slidably connected to the inner wall of the machine body, and the hydraulic cylinder is fixedly connected inside the machine body. The connecting frame is fixedly connected to the top of the hydraulic cylinder. The striking rod is rotatably connected to the inner wall of the machine body via a torsion spring. The torsion spring provides the striking rod with a force for rotational reset. The stop block is fixedly connected to the inner wall of the connecting frame. The lower support bar is fixedly connected to the inner wall of the connecting frame. The stop block contacts the striking rod. When the connecting frame is in its initial position, it contacts the inner wall of the groove between the upper support bar and the connecting frame, causing the steel plate to vibrate and facilitate the better removal of small pieces of workpiece that are stuck together. This significantly reduces the workload of subsequent material collection, reduces the burden on manual labor, and improves production efficiency. Large workpieces larger than the gap of the upper support bar remain on the surface of the device and are separated from small workpieces, which also reduces the difficulty of subsequent sorting.

[0007] Preferably, the screening mechanism includes: a screening plate, a receiving plate, a residue box, and a finished product box. The screening plate is hinged to the surface of the support leg, and the receiving plate is hinged to the bottom of the machine body via a connector. The residue box is located at the bottom of the screening plate, and the finished product box is located at the bottom of the receiving plate. The screening mechanism further includes: a second slider, a slide rail, a lower rotating block, an upper rotating block, and a guide chain. The slide rail is fixedly connected to the inner side of the support leg, the second slider is slidably connected to the surface of the slide rail, the lower rotating block and the upper rotating block are rotatably connected to the outer wall of the second slider, and the receiving plate is slidably connected to the inside of the upper rotating block. The screening plate is slidably connected to the inner wall of the lower rotating block, the guide chain is fixedly connected to the surface of the receiving plate, and the guide chain is fixedly connected to the bottom of the connecting frame. The slag box and the finished product box are equipped with handles on the left side. The slag will fall into the lower slag box through the holes on the screening plate, while the workpiece will slide into the finished product box below the receiving plate. This separates the workpiece from the slag, reducing the workload of subsequent cleaning processes. The up and down movement of the receiving plate and the screening plate also allows small pieces of workpiece and slag falling on their surface to slide off better, preventing material blockage. It also prevents slag from enveloping the workpiece and affecting subsequent production processes.

[0008] Preferably, the cleaning mechanism includes: a fixed frame, a roller brush, and a rotating shaft. The fixed frame is fixedly connected to the back of the crossbeam, the roller brush is fixedly connected to the circumferential surface of the rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the fixed frame. The cleaning mechanism also includes: a gear, a slider, an electric slide rail, and a rack. The gear is fixedly connected to the circumferential surface of the rotating shaft, the slider is slidably connected to the surface of the electric slide rail, the electric slide rail is fixedly connected to the inner wall of the fixed frame, the rack is fixedly connected to the top of the machine body, the gear is located on the movement trajectory of the rack, and the roller brush is located inside the fixed frame, providing a suitable surface environment for subsequent cutting. A suitable surface environment can extend the life of the internal lens of the laser head. Dust or particles on the steel plate may splash and contaminate the focusing lens at high temperatures, reducing light transmittance or even damaging optical components.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This laser cutting machine for metal material processing significantly reduces the workload of subsequent material collection, reduces manual labor burden, and improves production efficiency through the cooperation of the upper support bar, connecting frame, hydraulic cylinder, striking rod, stop block, and lower support bar. Large workpieces larger than the gap of the upper support bar remain on the surface of the device and are separated from small workpieces, which also reduces the difficulty of subsequent sorting.

[0011] 2. This laser cutting machine for metal material processing, through the cooperation of the following components—screen plate, receiving plate, slag box, finished product box, slider two, slide rail, rotating block, slide rail three, and guide chain—separates the workpiece from the slag, reducing the workload of subsequent cleaning processes. Furthermore, the up-and-down movement of the receiving plate and screen plate allows small pieces of workpiece and slag falling onto their surfaces to slide off more easily, preventing material blockage and preventing slag from enveloping the workpiece and affecting subsequent production processes.

[0012] 3. This laser cutting machine for metal material processing, through the cooperation of a fixed frame, roller brush, rotating shaft, gear, slider, electric slide rail, and rack, can clean the surface of the steel plate to provide a suitable surface environment for subsequent cutting and prevent cutting failures caused by the cutting head colliding with dirt.

[0023] 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.

[0024] Please see Figures 1-9One embodiment of the present invention is: a laser cutting machine for metal material processing, comprising a body 1, a crossbeam 2 slidably connected to the top of the body 1, a cleaning mechanism 3 and a cutting head 4 disposed on the back of the crossbeam 2, a support leg 5 fixedly connected to the bottom of the body 1, a support mechanism 6 and a screening mechanism 7 disposed inside the body 1, the support mechanism 6 comprising: an upper support bar 601, a connecting frame 602, a hydraulic cylinder 603, a striking rod 604, a stop block 605, and a lower support bar 606, the upper support bar 601 being fixedly connected to the inner wall of the body 1, the connecting frame 602 being slidably connected to the inner wall of the body 1, the hydraulic cylinder 603 being fixedly connected to the inside of the body 1, and the connecting frame 602 being... Fixedly connected to the top of the hydraulic cylinder 603, the striking rod 604 is rotatably connected to the inner wall of the machine body 1 via a torsion spring. The torsion spring provides the striking rod 604 with a force for rotational reset. The stop block 605 is fixedly connected to the inner wall of the connecting frame 602, and the lower support bar 606 is fixedly connected to the inner wall of the connecting frame 602. The stop block 605 contacts the striking rod 604. When the connecting frame 602 is in the initial position, it contacts the inner wall of the groove between the upper support bar 601 and the connecting frame 602, causing the steel plate to vibrate and promoting the better removal of small pieces of workpieces that are stuck together. This greatly reduces the workload of subsequent material collection, reduces the burden on manpower, and improves production efficiency. Large pieces of workpieces larger than the gap of the upper support bar remain on the surface of the device and are separated from small pieces of workpieces, which also reduces the difficulty of subsequent sorting.

[0025] Working principle: When the device is running, the hydraulic cylinder 603 extends its output end, pushing the connecting frame 602 upward. The connecting frame 602 drives the lower support bar 606 upward to be flush with the upper support bar 601, placing the material to be processed. After cutting, the hydraulic cylinder 603 retracts, and the connecting frame 602 drives the lower support bar 606 downward. As the lower support bar 606 moves away from the upper support bar 601, the gap between the upper support bars 601 increases, allowing the cut small pieces of workpiece to fall more easily to the screening mechanism 7 below. At the same time, the downward movement of the connecting frame 602... As the moving stop 605 moves downward, it comes into contact with the striking rod 604. As it continues to move downward, the striking rod 604 rotates around the torsion spring. The striking rod 604 strikes the material steel plate, causing the steel plate to vibrate and helping the small pieces of workpiece that are stuck together to come off more easily. This greatly reduces the workload of subsequent material collection, reduces the burden on manual labor, and improves production efficiency. Large workpieces that are larger than the gap of the upper support bar 601 remain on the surface of the device and are separated from the small workpieces, which also reduces the difficulty of subsequent sorting.

[0026] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the screening mechanism 7 includes: a screening plate 701, a receiving plate 702, a slag box 703, and a finished product box 704. The screening plate 701 is hinged to the surface of the support leg 5, the receiving plate 702 is hinged to the bottom of the machine body 1 through a connector, the slag box 703 is located at the bottom of the screening plate 701, and the finished product box 704 is located at the bottom of the receiving plate 702. The screening mechanism 7 also includes: a second slider 705, a slide rail 706, a lower rotating block 707, an upper rotating block 708, and a guide chain 709. The slide rail 706 is fixedly connected to the inner side of the support leg 5, and the second slider... 705 is slidably connected to the surface of slide rail 706. Lower rotating block 707 and upper rotating block 708 are rotatably connected to the outer wall of slider 705. Receiving plate 702 is slidably connected to the inside of upper rotating block 708. Screening plate 701 is slidably connected to the inner wall of lower rotating block 707. Guide chain 709 is fixedly connected to the surface of receiving plate 702 and to the bottom of connecting frame 602. Handles are installed on the left side of slag box 703 and finished product box 704. Slag falls through the holes in the screening plate into the lower slag box, while the workpiece slides into the finished product box below the receiving plate, thus separating the workpiece from the slag. The cleaning mechanism 3 reduces the workload of subsequent cleaning processes and allows small workpieces and slag falling onto its surface to slide off better, preventing material blockage. It also prevents slag from enveloping workpieces and affecting subsequent production processes. The cleaning mechanism 3 includes: a fixed frame 301, a roller brush 302, and a rotating shaft 303. The fixed frame 301 is fixedly connected to the back of the crossbeam 2, the roller brush 302 is fixedly connected to the circumference of the rotating shaft 303, and the rotating shaft 303 is rotatably connected to the inner wall of the fixed frame 301. The cleaning mechanism 3 also includes: a gear 304, a slider 305, an electric slide rail 306, and a rack. 307, gear 304 is fixedly connected to the circumferential surface of rotating shaft 303, slider 305 is slidably connected to the surface of electric slide rail 306, electric slide rail 306 is fixedly connected to the inner wall of fixed frame 301, rack 307 is fixedly connected to the top of machine body 1, gear 304 is located on the movement trajectory of rack 307, and roller brush 302 is located inside fixed frame 301 to provide a suitable surface environment for subsequent cutting. A suitable surface environment can extend the life of the internal lens of laser head. Dust or particles on steel plate may splash and contaminate focusing lens at high temperature, reduce light transmittance or even damage optical components.

[0027] Working principle: After cutting, small workpieces and slag fall together onto the surface of the receiving plate 702, and then slide onto the screen plate 701. At the same time, the connecting frame 602 moves, pulling the receiving plate 702 through the guide chain 709. The movement of the receiving plate 702 drives the upper rotating block 708 to move, which in turn drives the second slider 705 to move. The movement of the second slider 705 drives the lower rotating block 707 to move, which in turn drives the screen plate 701 to move. Through the up-and-down movement of the receiving plate 702 and the screen plate 701, the small workpieces and slag falling on their surfaces slide off more easily, and the slag is prevented from enveloping the workpieces and affecting subsequent production processes. When the small workpieces and slag fall onto the surface of the screen plate 701, the slag will fall through the holes on the screen plate 701 into the slag box 703 below, while the workpiece will slide into the finished product box 704 below the receiving plate 702, thus separating the workpieces from the slag and reducing the workload of subsequent cleaning processes.

[0028] After the steel plate is placed, if the surface of the steel plate is too dirty, the electric slide rail 306 will start to drive the slider 305 to move down. The slider 305 will move down and drive the rotating shaft 303 to move down. The rotating shaft 303 will move down and drive the roller brush 302 and gear 304 to move down. When the gear 304 contacts and meshes with the rack 307, the electric slide rail 306 will stop. At the same time, the roller brush 302 will also contact the steel plate. The crossbeam 2 will move and drive the rotating shaft 303 to move. The rotating shaft 303 will move and drive the gear 304 to move. The gear 304 will mesh with the rack 307 and rotate as the gear 304 moves. The rotation of the gear 304 will drive the rotating shaft 303 to rotate. The rotation of the rotating shaft 303 will drive the roller brush 302 to clean the surface of the steel plate and provide a suitable surface environment for subsequent cutting. A suitable surface environment can extend the life of the internal lens of the laser head. Dust or particles on the steel plate may splash and contaminate the focusing lens at high temperatures, reducing light transmittance or even damaging optical components.
