Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, in particular to a strip processing laser cutting machine. Background Art

[0002] The working principle of the strip processing laser cutting machine is to focus the laser beam emitted by the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0004] When existing laser cutting machines are used to handle sheet metal cutting operations, although high-speed airflow is used to remove the residue produced after cutting, due to the instant melting characteristics of metal materials, some slag cannot be completely discharged when encountering high-speed airflow, but is retained at the bottom of the sheet metal and quickly cooled and solidified.

[0017] Compared with the prior art, the present invention provides a strip processing laser cutting machine, which has the following beneficial effects:

[0018] 1. The present invention provides a pressing plate so that when the plate is pressed again, it will move downward together with the lower pressing plate. However, after the cutting of the plate is completed, the pressing plate will rise through the fourth spring rod to prop up the plate, so that the plate is suspended all around, so that the residue at the bottom of the plate can solidify faster and be processed.

[0019] 2. The present invention can pull the lower pressure plate by setting a pulling plate, and at the same time drive the third spring rod to compress and store force. In this way, the return thrust can be increased during rebound. This arrangement ensures that the lower pressure plate will not automatically rise after completing the downward movement, thereby achieving separation of the lower pressure plate and the pressing plate, so that the scraping mechanism can work regardless of the distance between the plate and the lower pressure plate.

[0020] 3. The present invention can perform a pulling operation on the pulling plate by setting a clamping mechanism. After the pulling plate moves downward, it can rebound with the help of the third spring rod. The rotating block can limit the position of the pulling plate. At this time, the pulling plate will be subject to the return thrust of the third spring rod. However, the rotating block will be restricted by the supporting block and cannot rotate, thereby fixing the pulling plate. This fixed state makes it impossible for the lower pressure plate to be reset, thereby increasing the distance between the plate and the lower pressure plate.

[0021] 4. The present invention arranges the swing plate to rotate back and forth so that the residue on the bottom of the plate can be scraped off by the curved scraper. The scraping area and the scraping angle can be adjusted by adjusting the different rotation angles of the arc rod and the second telescopic rod, so that the scraper can face different cutting shapes and process them.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: a strip processing laser cutting machine, comprising a base 1 and four groups of supporting legs 2, the top side walls of the four groups of supporting legs 2 are fixedly connected to the left and right sides of the base 1, a curved rod 5 is arranged on the top of the base 1, the bottom of the curved rod 5 is fixedly connected to the side wall of the base 1, two groups of first slide grooves 3 are opened on the inner wall of the base 1, the groove walls of the two groups of first slide grooves 3 are slidably connected with first sliders 4, a second slide groove 10 is opened at the middle end of the top of the curved rod 5, a third slide rod 11 is arranged on the inner wall of the second slide groove 10, the left and right sides of the third slide rod 11 are fixedly connected to the second slide groove 10, and the outer wall of the third slide rod 11 is slidably connected with a cutting device 6, and also includes:

[0035] The pressing mechanism 7 includes a fixed plate 701, and the left and right sides of the fixed plate 701 are fixedly connected to the first sliding block 4, the four corners of the top of the fixed plate 701 are fixedly connected to the first spring rods 702, the tops of the four groups of first spring rods 702 are fixedly connected to the lower pressing plate 704, the middle end of the top of the fixed plate 701 is fixedly connected to the bottom plate 712, the top of the bottom plate 712 is fixedly connected to the second spring rod 703, the top of the second spring rod 703 is fixedly connected to the top plate 710, the outer wall of the fourth spring rod 708 is fixedly connected to the moving ring 709, the front and rear of the moving ring 709 are fixedly connected to the moving plate 707, the outer walls of the two groups of third spring rods 711 are slidably connected to the pulling plate 705, and the lower pressing plate 704 can be pulled by setting the pulling plate 705 so that it cannot automatically rise after the next step, thereby preventing the lower pressing plate 704 and the pressing plate 706 from being in the same height after the cutting of the plate is completed.

[0036] The working principle of this embodiment is as follows: when the staff needs to inspect and cut the plate, the staff puts the plate on the lower pressing plate 704, and the plate will press the lower pressing plate 704 and the pressing plate 706, thereby causing the part to move downward. At this time, the pressing plate 706 will drive the fourth spring rod 708 to move downward, and the fourth spring rod 708 in the downward movement will drive the moving ring 709 to move downward synchronously, so that the moving ring 709 will also drive the moving plate 707 to move downward when moving downward, and the top plate 710 will be pushed downward by the fourth spring rod 708, causing the top plate 710 to move downward, so that the top plate 710 will push The second spring rod 703 and the third spring rod 711 are moved downward at the same time. When the top plate 710 slides on the third spring rod 711, it will drive the pulling plate 705 to move, so that the pulling plate 705 will contact the lower pressure plate 704, and the pulling plate 705 will enter the interior of the clamping mechanism 8 and fix it. At this time, the cutting device 6 is started to cut the plate. When the plate is cut, the plate will have lost a part of its weight after cutting, causing the pressing plate 706 to start to rebound. At this time, the lower pressure plate 704 is fixed by the pulling plate 705 and cannot rise, causing the plate to be lifted up by the pressing plate 706 and float in the air.

[0037] Example 2: Please refer to Figure 5-Figure 6 On the basis of the first embodiment, the present invention provides a technical solution: a clamping mechanism 8, the clamping mechanism 8 includes a connecting block 801, the bottom of the connecting block 801 is fixedly connected to the fixed plate 701, the top of the connecting block 801 is rotatably connected to two groups of rotating blocks 804 through a rotating shaft, the left and right sides of the connecting block 801 are provided with arc grooves 802, the inner walls of the arc grooves 802 are provided with second sliding bars 805, the upper and lower ends of the two groups of second sliding bars 805 are fixedly connected to the arc grooves 802, the outer walls of the two groups of second sliding bars 805 are slidably connected to second sliding blocks 808, the two groups of second sliding blocks 808 are fixedly connected to the side away from the connecting block 801 with elastic bands 803, and the two groups of elastic bands 803 are away from the second One side of the two sliders 808 is fixedly connected to the rotating block 804, and the left inner walls of the two groups of arc-shaped grooves 802 are fixedly connected with springs 807. The two groups of springs 807 are fixedly connected with support blocks 806 on the side close to the second slide bar 805. By setting the support block 806, the second slider 808 can be restricted so that it cannot move downward directly. The second slider 808 needs to continue to move until the driving force is applied to cause the spring 807 to contract, causing the support block 806 to move sideways, so that the second slider 808 moves downward. At this time, the scraping mechanism 9 has completed its work and will not affect it. The clamping mechanism 8 is set to have two groups that are symmetrically arranged with the middle of the base 1 as the center.

[0038] The working principle of this embodiment is as follows: at this time, the motor 902 is started to work, so that the motor 902 drives the rotating rod 903 to rotate, and the rotation of the rotating rod 903 drives the second telescopic rod 911 to rotate, and the second telescopic rod 911 drives the arc rod 910 to rotate, and the arc rod 910 drives the first telescopic rod 909 to rotate, so that the first telescopic rod 909 drives the contact block 908 to rotate synchronously, so that the contact block 908 drives the rotating plate 904 to rotate, so that the rotating plate 904 will generate a shaking force when rotating back and forth, so that the swinging plate 906 will slide back and forth on the slide plate 905, so that the scraper 907 on the swinging plate 906 scrapes off the residue at the bottom of the plate, thereby completing the work.

[0039] Example 3: Please refer to Figure 7-Figure 8 On the basis of the first and second embodiments, the present invention provides a technical solution: a scraping mechanism 9, the scraping mechanism 9 includes a protective shell 901, the bottom of the protective shell 901 is fixedly connected to the top of the base 1, the bottom of the inner wall of the protective shell 901 is rotatably connected to a rotating rod 903 through a bearing, a motor 902 is arranged on the top of the rotating rod 903, the output end of the motor 902 is fixedly connected to the rotating rod 903, the rotating rod 903 passes through the curved rod 5, a rotating plate 904 is arranged on the side of the protective shell 901 close to the base 1, a slide plate 905 is fixedly connected to the inner wall of the rotating plate 904, a swing plate 906 is slidably connected to the outer wall of the slide plate 905, and three groups of scrapers 907 are fixedly connected to the top of the swing plate 906, a contact block 908 is fixedly connected to the side of the rotating plate 904 close to the protective shell 901, and a first telescopic rod 909 is fixedly connected to the side of the contact block 908 close to the protective shell 901, and the first telescopic rod 909 is fixedly connected to the side of the first telescopic rod 909. The side of the retractable rod 909 close to the protective shell 901 is fixedly connected to an arc rod 910, and the side of the arc rod 910 close to the protective shell 901 is rotatably connected to a second telescopic rod 911. The side of the second telescopic rod 911 close to the protective shell 901 is slidably connected to the rotating rod 903.

The scraping mechanism 9 is set to two groups, and both are symmetrically arranged with the middle of the base 1 as the center.

[0040] The working principle of this embodiment is as follows: after the residue at the bottom of the plate is scraped off, the pulling plate 705 inside the rotating block 804, the third spring rod 711 at the bottom of the pulling plate 705 will rebound, thereby continuously pushing the pulling plate 705, so that the rotating block 804 starts to rotate outward, but will be blocked by the support block 806, resulting in the second slider 808 being unable to move downward, making the rotating block 804 unable to rotate, but the continuous push of the third spring rod 711 makes the rotating block 804 drive the elastic belt 803 to move downward, thereby pulling the second slider 808 to move downward, thereby pushing the support block 806 to push the spring 807 to compress, so that the second slider 808 starts to move downward, so that the second slider 808 cancels the restriction on the rotating block 804, so that the pulling plate 705 can rise normally to complete the work.
