[0002] The power distribution cabinet body is an important part of the power system, and the processing quality and efficiency of the power distribution cabinet body directly affect the stability and reliability of the entire power system. With the rapid development of the power industry and the continuous progress of technology, the processing requirements for the power distribution cabinet body are increasingly improved. Laser cutting technology, as a high-precision and high-efficiency cutting method, has been widely used in the field of power distribution cabinet body processing due to its fast cutting speed, good cutting quality, small heat-affected zone and other advantages.

[0003] The traditional laser cutting equipment often has difficulty in effectively pressing and fixing the plate during the cutting process, which leads to the movement or vibration of the plate during the cutting process, thereby affecting the cutting precision and quality.

[0031] When the present invention is used, a sheet of material to be cut and of a certain size is placed between the four positioning blocks 15 on the bottom plate 1. In the initial state, the smoking plug 34 is against the inner top of the smoking tube 4, the air injection plug 24 is at the highest position, the tension spring 25 is stretched, and the first frame 5 and the poking rod 7 are moved downward by the cylinder 9. During the downward movement of the first frame 5, the four second springs 21 are provided, so that the second frame 12 can move downward accordingly. During the downward movement of the poking rod 7, the tension generated by the stretched tension spring 25 can gradually move the air injection plug 24 downward, thereby generating a suction effect, and the external air is sucked into the upper wind tube 6 through the air inlet pipe 17;

[0032] When the first frame 5, the poking rod 7 and the second frame 12 move downward synchronously to the mutual contact of the second frame 12 and the bottom plate 1, the tension spring 25 restores to the original length, and then the first frame 5 continues to move downward by the air cylinder 9, at this time, the second frame 12 cannot continue to move downward because the second frame 12 abuts against the bottom plate 1, so that the first frame 5 can gradually approach the second frame 12, in the process that the first frame 5 gradually approaches the second frame 12 to the mutual contact of the first frame 5 and the second frame 12, the connecting rod 20 and the smoking plug 34 gradually move to the direction close to the smoke collecting box 3, the second spring 21 is compressed, so that the smoke in the smoking cylinder 4 is extruded into the smoke collecting box 3 through the smoke collecting pipe 35 to be collected, in this process, the telescopic rod 18 and the pressing block 22 move to the direction close to the bottom plate 1, the pressing block 22 will be in contact with the plate between the four positioning blocks 15 in advance, and the telescopic rod 18 is retracted with the continuous downward movement of the first frame 5, the first spring 19 is compressed, thereby being able to compress and fix the positions of the four corners of the plate, in this process, the poking rod 7 will continue to move downward, but the air injection plug 24 will not move downward because the tension spring 25 restores to the original length;

[0033] When the first frame 5 and the second frame 12 are in contact with each other, the driving motor 8 is started, the rotating shaft 30 and the cam 28 rotate one circle, in the process that the cam 28 rotates one circle, through the setting of the two abutting plates 29, the two abutting rods 37 and the two third springs 38, the two first oil plugs 36 can be moved away from the cam 28 and moved close to the cam 28 in turn, so that the hydraulic oil in the two first oil cylinders 11 can be extruded into the second oil cylinder 14 and then sucked back into the first oil cylinder 11 in turn, thereby the second oil plug 31 in the second oil cylinder 14 can reciprocate once, through the setting of the moving rod 32, the laser cutter 33 can reciprocate once, because the two second oil cylinders 14 are distributed vertically, so that the plate can be cut once in the horizontal direction and once in the vertical direction, the double-line cutting is completed, in the cutting process, because the first frame 5 and the second frame 12 enclose the cutting operation area, so that the flying of the debris can be avoided, and the safety is improved;

[0034] After the cutting of the plate is completed, the first frame 5 is moved upward by the air cylinder 9. In the initial state, the second spring 21 is compressed, and the first frame 5 is gradually separated from the second frame 12 first. The pressing block 22 is moved upward and no longer tightly fixes the plate. The connecting rod 20 and the smoke suction plug 34 are gradually moved away from the smoke collecting box 3 until the smoke suction plug 34 abuts against the inner top of the smoke suction cylinder 4, thereby generating a suction effect. The smoke generated during cutting is sucked into the smoke suction cylinder 4 through the smoke suction pipe 23. In this way, the harmful smoke can be treated to avoid being inhaled by the human body. Subsequently, as the first frame 5 continues to move upward, the smoke suction plug 34 abuts against the inner top of the smoke suction cylinder 4, thereby enabling the first frame 5 and the second frame 12 to move upward synchronously. In the process of the synchronous upward movement of the first frame 5 and the second frame 12, the poking rod 7 on the first frame 5 again contacts the air injection plug 24 and moves the air injection plug 24 upward to the highest position. The tension spring 25 is again elongated, thereby generating a pressing effect. The air in the air inlet cylinder 6 is pressed into the air outlet box 16 through the air outlet pipe 10 and is sprayed out through the nozzle 26 on the air outlet box 16. In this way, the cut plate can be cooled to avoid melting, oxidation and other phenomena on the cutting surface, thereby improving the cutting quality and the cleanliness of the cutting surface.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
