Description

Technical Field

[0001] The utility model relates to the technical field of door panel processing, in particular to a laser cutting machine for door panels. Background Art

[0002] Metal door panel laser cutting machine is an advanced equipment specially used for cutting metal door panel materials. It uses a high-energy-density laser beam as a heat source, focuses the laser beam into a very small spot through an optical system, and irradiates it on the surface of the metal door panel. When the laser beam contacts the metal, its energy is absorbed and converted into heat energy, which rapidly heats the metal locally to above the melting point. At the same time, it is combined with a high-speed airflow (such as nitrogen, oxygen, etc.) to blow away the molten metal, thereby achieving the cutting of the metal door panel.

[0003] When existing laser cutting machines for door panels are used to process lock holes in metal door panels, some door panels themselves have bulges or depressions, and the two ends of the door panels are raised, which will cause the focus to shift during cutting, making the cutting surface uneven and reducing the processing and cutting quality of the door panel lock holes.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0020] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0021] This embodiment mainly describes a laser cutting machine for door panels, as follows:

[0022] like Figure 1-4 As shown, a laser cutting machine for door panels comprises a workbench 1, an inner cavity of the workbench 1 is provided with a supporting rack 2, a slide groove 3 is provided on the front side of the upper end of the workbench 1, a driving component 4 is provided inside the slide groove 3, an outer surface of the driving component 4 is threadedly connected with an adjusting frame 5, the adjusting frame 5 is arranged in an L shape, a metal sheet 6 is placed on the supporting rack 2, a pushing component 7 is provided on the rear side of the upper end of the workbench 1, a positioning plate 8 is fixedly installed at the front end of the pushing component 7, a groove 9 is provided on the upper side of the front end of the positioning plate 8, an adjusting component 10 is arranged in the groove 9, a first cylinder 11 is fixedly installed on the left and right sides of the upper end of the adjusting component 10, a flattening plate 12 is fixedly installed on the output ends of the two first cylinders 11, a laser generator 13 is movably connected to the upper end of the adjusting frame 5, a laser head 14 is fixedly installed at the lower end of the laser generator 13, and the laser generator 13 generates a high-intensity laser beam. After these light beams are focused by the lens system in the laser head 14, a very small light spot is formed. The laser head 14 moves according to the preset cutting trajectory and simultaneously emits a focused laser beam to the metal sheet 6 for laser cutting. The positioning plate 8 applies pressure to the metal sheet 6 to limit the position of the metal sheet 6 to prevent the metal sheet 6 from shifting during laser cutting. The first cylinder 11 pushes the leveling plate 12 downward to apply pressure to the left and right ends of the metal sheet 6 to position it. This pressure can flatten the slight undulations or twists of the metal sheet 6 to make it smoother and prevent the two ends of the metal sheet 6 from warping. The leveling of the metal sheet 6 helps the subsequent cutting processing operations and improves the processing accuracy and product quality.

[0023] A support leg 15 is fixedly installed at each of the four corners of the lower end of the workbench 1 , and the support leg 15 plays a supporting role on the workbench 1 .

[0024] like Figure 2 As shown, the driving assembly 4 includes a screw rod 41, a first servo motor 42 is fixedly installed on the right end of the screw rod 41, the first servo motor 42 is fixedly connected to the front side of the right end of the workbench 1, the screw rod 41 is movably connected in the slide groove 3, and the adjusting frame 5 is threadedly connected to the outer surface of the screw rod 41. The screw rod 41 is driven to rotate by the first servo motor 42, thereby driving the adjusting frame 5 to move left and right along the screw rod 41, so that the laser head 14 can laser cut the metal plate 6 to process the lock hole.

[0025] like Figure 3 As shown, the pushing assembly 7 includes a vertical plate 71, a second cylinder 72 is fixedly installed at the rear end of the vertical plate 71, and the positioning plate 8 is fixedly connected to the output end of the second cylinder 72. When the second cylinder 72 is started, the positioning plate 8 is pushed forward to contact the metal plate 6, and the metal plate 6 is pushed forward to abut against the inner wall of the workbench 1.

[0026] like Figure 4 As shown, the adjustment component 10 includes a positive and negative threaded rod 101, and a second servo motor 102 is fixedly installed on the right end of the positive and negative threaded rod 101. An adjustment plate 103 is threadedly connected to the left and right sides of the outer surface of the positive and negative threaded rod 101. The adjustment plate 103 and the leveling plate 12 maintain a parallel position relationship. The leveling plate 12 is located below the adjustment plate 103. The second servo motor 102 is fixedly connected to the right end of the positioning plate 8, and the first cylinder 11 is fixedly connected to the upper end of the adjustment plate 103. The positive and negative threaded rod 101 is driven to rotate by the second servo motor 102. Since the left and right ends of the positive and negative threaded rod 101 have threads with different rotation directions, the nuts or adjustment plates 103 with nuts arranged at both ends of the positive and negative threaded rod 101 can move relative to each other. When the two adjustment plates 103 move left and right along the positive and negative threaded rod 101, the distance between the two leveling platens 12 is adjusted.

[0027] When in use, the metal sheet 6 is placed on the supporting rack 2, and the positioning plate 8 is pushed forward by starting the second cylinder 72 to contact the metal sheet 6, and the metal sheet 6 is pushed forward to abut against the inner wall of the workbench 1, and the positioning plate 8 exerts pressure on the metal sheet 6 to limit the position of the metal sheet 6, so as to prevent the metal sheet 6 from being offset during laser cutting. The second servo motor 102 drives the positive and negative threaded rod 101 to rotate. Since the left and right ends of the positive and negative threaded rod 101 have threads with different rotation directions, the nuts or adjustment plates 10 with nuts provided at the two ends of the positive and negative threaded rod 101 are matched with the positive and negative threaded rod 101. The two adjustment plates 103 can move relative to each other. When the two adjustment plates 103 move left and right along the forward and reverse threaded rods 101, the spacing between the two flattening plates 12 is adjusted. The position of the flattening plates 12 is adjusted according to the length of the metal sheet 6 to improve the adaptability. When the flattening plates 12 are pushed downward by the first cylinder 11, the left and right ends of the metal sheet 6 are pressed and positioned. This pressure can flatten the small undulations or twisted parts of the metal sheet 6 to make it more flat, and prevent the two ends of the metal sheet 6 from warping. The flattening of the metal sheet 6 is helpful for the subsequent cutting processing operation, and improves the processing accuracy and product quality.
