Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting equipment, in particular to a protective device for the loading area of a laser pipe cutting machine. Background Technique

[0002] When a pipe is cut by a laser cutting machine, since the sparks generated by the cutting will splash around, this situation is extremely likely to cause the sparks to splash onto the clothing or skin of the staff, posing a serious threat to the safety of the staff. Therefore, a protective device needs to be installed around the equipment that is performing laser pipe cutting to protect the staff from the potential safety hazards caused by the splashing of sparks.

[0003] In order to address the above problems, Chinese Patent CN213318423U, a protective device for a laser pipe cutting machine and a laser pipe cutting machine, points out that the protective device can be applied to the loading and unloading process of a laser pipe cutting machine. While ensuring sufficient working space for the pipe fittings, it can provide a certain degree of shielding for the pipe fittings, effectively isolating the staff from the area with potential safety hazards, avoiding the pipe fittings from shaking out during the processing and causing personal injury to the operator, and ensuring the personal safety of the operator. Through this kind of barrier, it is possible to prevent problems endangering the safety of personnel during the pipe cutting operation. However, although the above patent can solve the above technical problems, there are still certain technical problems. According to the above patent, the patent cannot effectively achieve full coverage. Secondly, it cannot adapt to laser cutting machines of different lengths, reducing the applicability. Secondly, the safety factor is relatively low.

[0004] Therefore, in order to be able to adapt to the installation of laser cutting machines of different lengths, achieve full coverage of the loading area of the laser cutting machine, and be able to realize the individual or synchronous lifting of each group of protective plates for easy viewing of the pipe feeding situation, a protective device for the loading area of a laser pipe cutting machine is hereby proposed to solve the technical problems existing in the above-mentioned prior art. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a protective device for the loading area of a laser pipe cutting machine, which solves the problems that the existing protective device cannot provide comprehensive protection for the loading area of the laser cutting machine, cannot adapt to the installation of protective plates of laser cutting machines of different lengths, and has a low installation coefficient.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A protective device for the loading area of a laser pipe cutting machine, including a liftable device guard plate, and the liftable device guard plate includes a first protective plate, a second protective plate, a third protective plate, and a fourth protective plate. It also includes a driving structure and a sliding mounting structure connected to the laser cutting machine. The driving structure is installed on the liftable device guard plate. The first protective plate, the second protective plate, the third protective plate, and the fourth protective plate can be spliced together through a connecting plate. A front baffle for the loading area is installed at the left end of the first protective plate, and a rear baffle device for the loading area is installed at the right end of the fourth protective plate. Induction components are installed at the connection between the front baffle for the loading area and the first protective plate and at the connection between the fourth protective plate and the rear baffle device for the loading area. The induction components are linked and controlled with the driving structure. The induction components are divided into two groups. The connection between the front baffle for the loading area and the first protective plate is the first induction structure, and the connection between the fourth protective plate and the rear baffle device for the loading area is the second induction structure. The first induction structure includes a front limit switch, a front limit mounting plate, and a front limit induction plate. The second induction structure includes a rear limit induction plate, a rear limit switch, and a rear limit mounting plate. The front limit mounting plate is installed on the side of the front baffle for the loading area, the front limit induction plate is installed on the surface of the first protective plate, and a front limit switch is installed on the front limit mounting plate. A rear limit mounting plate is installed on the inner side surface of the rear baffle device for the loading area, a rear limit induction plate is installed on the side surface of the fourth protective plate, and a rear limit switch is installed on the rear limit mounting plate. The driving structure can drive the liftable device guard plate to lift synchronously and asynchronously.

[0007] Through the above technical solutions, further, the front limit switch and the rear limit switch are at the same height.

[0008] Further, mounting surfaces for installing the sliding mounting structure are provided on the side surfaces of the first protective plate, the second protective plate, the third protective plate, and the fourth protective plate.

[0009] As a preferred technical solution, the sliding mounting structure includes an automatic lifting device mounting plate installed on the laser pipe cutting machine and a guide rail installed on the mounting surface. A slider limit is installed at the upper end of the guide rail, and a slider is movably installed on the surface of the slider limit. The automatic lifting device mounting plate is connected to the slider.

[0010] Further, the driving structure includes a lifting cylinder, a cylinder rod connecting plate, a cylinder mounting plate, and a cylinder rod. The cylinder mounting plate is installed on the laser pipe cutting machine, a lifting cylinder is installed on the upper end surface of the cylinder mounting plate, a cylinder rod is provided at the upper end of the lifting cylinder, and cylinder rod connecting plates are installed on the side surfaces of the first protective plate, the second protective plate, the third protective plate, and the fourth protective plate. The cylinder rod is connected to the cylinder rod connecting plate through bolts.

[0011] As a preferred technical solution, observation windows are provided on the sides of the first protective plate, the second protective plate, the third protective plate, and the fourth protective plate, and the observation windows are installed on the sides of the first protective plate, the second protective plate, the third protective plate, and the fourth protective plate through window pressing plates.

[0012] Compared with the prior art, the present utility model provides a protective device for the loading area of a laser pipe cutting machine, which has the following beneficial effects:

[0013] 1. This lifting protective device can completely isolate the loading area (cutting area) of the laser cutting machine through the liftable device guard plate and the driving structure, and can effectively protect the operator from being pinched, impacted, etc. during the working process of the pipe cutting machine, ensuring effective protection.

[0014] 2. The four groups of protective plates are connected through connecting plates, enabling them to be adaptively installed according to laser pipe cutting machines of different lengths, thus improving the applicability of the lifting protective device.

[0015] 3. In order to improve safety, only when the protective plate rises and its front and rear limit switches are both effective can the laser cutting machine perform cutting, improving the safety of the lifting protective device;

[0016] 4. When cutting the pipe, in order to facilitate viewing the feeding situation of the pipe, it is not convenient to overall observe the feeding situation of the pipe only from the observation window. Therefore, each group of protective plates corresponds to a lifting cylinder, which can realize the individual lifting of the protective plate and can also realize synchronous lifting. In this way, when viewing the feeding situation of the pipe, a group of protective plates can be individually lowered slightly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment

[0031] Please refer to Figure 1-11, the present utility model provides the following technical solutions: A protective device for the loading area of a laser pipe cutting machine, including a liftable device guard plate 2, and the liftable device guard plate 2 includes a first protective plate 201, a second protective plate 202, a third protective plate 203, and a fourth protective plate 204. It also includes a driving structure and a sliding mounting structure connected to the laser cutting machine. The driving structure is installed on the liftable device guard plate 2. The first protective plate 201, the second protective plate 202, the third protective plate 203, and the fourth protective plate 204 can be spliced together through a connecting plate 19. A front baffle 1 for the loading area is installed at the left end of the first protective plate 201, and a rear baffle device 3 for the loading area is installed at the right end of the fourth protective plate 204. Induction components are installed at the connection between the front baffle 1 for the loading area and the first protective plate 201 and at the connection between the fourth protective plate 204 and the rear baffle device 3 for the loading area. The induction components are linked and controlled with the driving structure. The induction components are divided into two groups. The connection between the front baffle 1 for the loading area and the first protective plate 201 is the first induction structure, and the connection between the fourth protective plate 204 and the rear baffle device 3 for the loading area is the second induction structure. The first induction structure includes a front limit switch 16, a front limit mounting plate 17, and a front limit induction plate 18. The second induction structure includes a rear limit induction plate 11, a rear limit switch 12, and a rear limit mounting plate 15. The front limit mounting plate 17 is installed on the side of the front baffle 1 for the loading area, the front limit induction plate 18 is installed on the surface of the first protective plate 201, and the front limit switch 16 is installed on the front limit mounting plate 17. The rear limit mounting plate 15 is installed on the inner side of the rear baffle device 3 for the loading area, the rear limit induction plate 11 is installed on the side of the fourth protective plate 204, and the rear limit switch 12 is installed on the rear limit mounting plate 15. The driving structure can drive the liftable device guard plate 2 to lift synchronously and asynchronously.

[0032] In this implementation plan, the specific working principle is as follows: during use, first install the driving device and the sliding mounting structure on the laser pipe cutting machine, then install the liftable device guard plate 2 on the sliding mounting structure, and then place the pipe on the laser pipe cutting machine. At this time, before operation, the driving structure drives the four groups of guard plates (i.e., the first guard plate 201, the second guard plate 202, the third guard plate 203, and the fourth guard plate 204) to rise until the front limit switch 16 and the rear limit switch 12 come into effect simultaneously. Then the laser pipe cutting machine starts to cut the pipe, which can greatly improve the safety of the lifting protection device and prevent the laser from starting to cut before rising to a safe distance, causing sparks to splash onto the staff's clothing or skin and posing a safety hazard. Secondly, the four groups of guard plates are spliced together by the connecting plate 19, so they can be installed on laser pipe cutting machines with different lengths, thus improving the applicability of the lifting protection device. Secondly, although there are observation windows 9 on the guard plates, it is impossible to fully observe the feeding situation of the pipe. Therefore, in this protection device, the lifting cylinder 5 can independently control a group of guard plates to lift, so that it can be lowered to a certain height when not all of them need to be lifted, facilitating the staff to observe the feeding situation of the pipe, thus facilitating the staff's observation.

[0033] In order to ensure that after the guard plate rises, the front limit switch 16 and the rear limit switch 12 can come into effect simultaneously, the front limit switch 16 and the rear limit switch 12 are at the same height.

[0034] For easy installation on the laser pipe cutting machine, please refer specifically to Figure 1 、 Figure 7 、 Figure 9 It can be seen that mounting surfaces for installing the sliding mounting structure are provided on the sides of the first guard plate 201, the second guard plate 202, the third guard plate 203, and the fourth guard plate 204.

[0035] According to the above, for the specific sliding mounting structure, you can refer specifically to Figure 9 It can be seen that the sliding mounting structure includes an automatic lifting device mounting plate 4 installed on the laser pipe cutting machine, and a guide rail 7 installed on the mounting surface. A slider limit 14 is installed at the upper end of the guide rail 7, and a slider 8 is movably installed on the surface of the slider limit 14. The automatic lifting device mounting plate 4 is connected to the slider 8.

[0036] For the specific driving structure, you can refer specifically to, for example, Figure 5 and in combination with Figure 1It can be seen that the driving structure includes a lifting cylinder 5, a cylinder rod connecting plate 6, a cylinder mounting plate 13, and a cylinder rod 20; the cylinder mounting plate 13 is mounted on the laser pipe cutting machine, the lifting cylinder 5 is mounted on the upper end surface of the cylinder mounting plate 13, the upper end of the lifting cylinder 5 is provided with the cylinder rod 20, and the cylinder rod connecting plates 6 are mounted on the sides of the first protective plate 201, the second protective plate 202, the third protective plate 203, and the fourth protective plate 204. The cylinder rod 20 is connected to the cylinder rod connecting plate 6 by bolts. The lifting cylinder 5 drives the cylinder rod connecting plate 6 to move up and down, thereby driving the corresponding protective plate to move up and down.

[0037] For the convenience of observation, reference can be made specifically to Figure 5 It can be seen that observation windows 9 are provided on the sides of the first protective plate 201, the second protective plate 202, the third protective plate 203, and the fourth protective plate 204. The observation windows 9 are mounted on the sides of the first protective plate 201, the second protective plate 202, the third protective plate 203, and the fourth protective plate 204 through window pressing plates 10.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
