This laser machine uses imported YAG gem rod laser tubes, which have great cutting ability and are well absorbed by metals.

[0003] For example, a machine tool laser tube cutting machine with a publication number of CN218253465U specifically relates to the technical field of laser tube cutting machines, including a machine tool body, a left chuck device, a laser tube cutting machine and a right chuck device. A lifting assembly is arranged above the machine tool body, and the lifting assembly includes a fixed bottom frame, a double-rotation screw rod 1 is rotatably installed inside the fixed bottom frame, and the left and right sides of the double-rotation screw rod 1 are both threadedly connected to a lower moving seat, and a connecting pad is arranged above the fixed bottom frame, and connecting seats are fixedly installed on the left and right sides of the upper surface of the connecting pad plate, and a double-rotation screw rod 2 is rotatably installed between the two connecting seats, and the left and right sides of the double-rotation screw rod 2 are both threadedly connected to an upper moving seat, and a supporting roller is rotatably installed on the top of the upper moving seat. However, the above-mentioned laser tube cutting machine generates a small amount of sparks during the cutting process because it cuts tubes by laser, but the above-mentioned laser tube cutting machine does not have a protective device. When the operator stands on one side of the machine body, there is a possibility of burns. Utility Model Content

[0013] A further preferred technical solution of the utility model is that the closing piece is elastic.

[0014] A further preferred technical solution of the utility model is that abutment is formed between two adjacent closing pieces.

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] 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.

[0025] Figure 1 and Figure 2 As shown, a laser tube cutting machine with a laser protective cover includes a frame 1, a body 2 slidably connected to the frame 1, and a laser cutting body 3 fixedly connected to the body 2. Therefore, when the laser tube cutting machine is used to cut the tube, the body 2 controls the laser cutting body 3 to move on the frame 1 until it moves to the position where the tube needs to be cut. At this time, the laser cutting body 3 can perform corresponding cutting on the tube. A baffle plate 4 is fixedly connected to the body 2. The transverse cross-section of the baffle plate 4 is square. There is a gap between the baffle plate 4 and the laser cutting body 3 to prevent the baffle plate 4 from affecting the use of the laser cutting body 3 when the laser cutting body 3 cuts the tube. This design ensures that the laser cutting body 3 can operate normally when shielding sparks, and the width of the baffle plate 4 gradually decreases from bottom to top.

[0026] Figure 3-Figure 5As shown, there are several slide plates 5 slidably connected to the lower part of the baffle plate 4, and several mounting grooves 13 are opened on the baffle plate 4. The slide plates 5 are located in the mounting grooves 13 and slide. Therefore, when the machine body 2 moves downward, as the machine body 2 moves downward, the distance between the laser cutting body 3 and the pipe changes. At this time, the pipe pushes the slide plate 5 to gradually slide into the mounting groove 13, thereby changing the shielding range of the slide plate 5. This design enables the shielding range of the slide plate 5 to change according to the movement of the machine body 2, so that the shielding effect of the slide plate 5 and the baffle plate 4 is better, and the laser cutting body 3 can be more comprehensively shielded. Moreover, since the length of the slide plate 5 is greater than the depth of the mounting groove 13, the slide plate 5 cannot completely slide into the mounting groove 13, thereby avoiding the slide groove sliding into the mounting groove 13 and affecting the shielding. Several slide plates 5 are butted head to tail to avoid gaps between adjacent two slide plates 5. This design further improves the shielding effect.

[0027] Figure 3-Figure 5 As shown, a plurality of springs 12 are fixedly connected between the mounting groove 13 and the slide plate 5 for pushing the slide plate 5 to slide. Therefore, when the machine body 2 drives the laser cutting body 3 to slide downward, the slide plate 5 gradually slides into the mounting groove 13 due to the push of the pipe. At this time, the spring 12 in the mounting groove 13 is deformed due to the squeezing of the slide plate 5 until the machine body 2 drives the laser cutting body 3 to move upward. At this time, the distance between the laser cutting body 3 and the pipe becomes larger, and the deformed spring 12 can push the slide plate 5 to slide out of the mounting groove 13, thereby completely covering the laser cutting body 3. This design facilitates the reset of the slide plate 5.

[0028] Figure 3-Figure 5 As shown, a limiting groove 11 is provided on both side walls of each mounting groove 13, and a limiting block 14 is fixedly connected to both side walls of each slide plate 5. Therefore, when the slide plate 5 slides, the limiting block 14 slides together with the slide plate 5 in the limiting groove 11. This design serves to limit the sliding range of the slide plate 5, thereby preventing the slide plate 5 from separating from the mounting groove 13 during the sliding process, thereby affecting the subsequent shielding of the laser cutting body 3.

[0029] Figure 3-Figure 5 As shown, each slide plate 5 is provided with a cavity 9 and a through slot 8 communicating with the cavity 9, a fan 7 is fixedly connected in the through slot 8, and a plurality of circular holes 6 communicating with the cavity 9 are provided on a side wall of the slide plate 5 away from the through slot 8. Therefore, when the temperature of the pipe is high after cutting, the fan 7 is turned on. At this time, the wind blown by the fan 7 enters the cavity 9. At this time, the cavity 9 can buffer the wind speed to prevent the faster wind speed from affecting the cutting of the laser cutting body 3. The buffered wind is then blown out through the through hole to cool the pipe to prevent the operator from being burned when checking the pipe after cutting. This design further improves the safety performance of the laser cutting machine.

[0030] Figure 3-Figure 5As shown, a plurality of closing pieces 10 are fixedly connected to the inner wall of the circular hole 6, and abutment is formed between two adjacent closing pieces 10. The closing pieces 10 are elastic. When the fan 7 is started, the wind can blow the closing pieces 10 to deform them so that they rotate out of the circular hole 6. At this time, the circular hole 6 is open and the wind can be blown out smoothly. When the laser cutting body 3 stops cutting, the fan 7 is turned off. At this time, due to the disappearance of the wind, the deformed closing piece 10 is reset, thereby closing the circular hole 6 to prevent external dust from entering the circular hole 6 and the cavity 9.

[0031] The above is an introduction to a laser tube cutting machine with a laser protective cover provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
