Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting equipment technology, specifically relating to a protective device for a pipeline laser cutting machine. Background Technology
[0002] In modern assembly line production, some metal pipes are made by shaping continuous steel plates into the required shape through a series of forming processes, leaving a weld seam of a certain width. Then, they are welded by welding equipment to form a complete pipe. Finally, a laser cutting machine cuts the complete pipe to the required length. During cutting, the laser cutting machine moves forward synchronously with the pipe and around the pipe, always facing the central axis of the pipe, and automatically resets after completing one cut, and so on.
[0003] A laser cutting machine uses a laser emitted from a laser source to focus a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.
[0004] To improve cutting efficiency, two opposing laser cutting machines are used to rotate synchronously to cut the pipe. In this way, the laser cutting machine completes the pipe cutting by rotating half a revolution of the machine casing, which greatly improves the cutting efficiency.
[0005] However, when two laser cutting machines are set up opposite each other, during operation, the laser may pass through the side wall of the pipe and hit the opposite laser cutting machine, thereby damaging the laser cutting machine. Utility Model Content
[0006] This utility model provides a protective device for a pipeline laser cutting machine, aiming to solve the technical problems existing in the background art.

[0008] A fixed bracket is fixedly installed, with one end extending into the pipe from the weld seam.
[0009] A shielding component is installed inside the pipe and between the two laser cutting machines. The projection of the central axis of the pipe in any direction perpendicular to the length of the pipe falls within the projection range of the shielding component, which is used to shield the laser.
[0010] The connector is connected at one end to the fixing frame and at the other end to the shielding component.
[0011] In one possible implementation of the protective device for a pipeline laser cutting machine provided by this utility model, the shielding member has a columnar structure.
[0012] In one possible implementation of the protective device for a pipeline laser cutting machine provided by this utility model, the shielding member has a circular cross-section perpendicular to the axis.

[0014] In one possible implementation of the protective device for a pipeline laser cutting machine provided by this utility model, the shielding member is a continuously variable diameter columnar structure with a large diameter end and a small diameter end, the small diameter end facing the fixing frame and connected to the connecting member.
[0015] In one possible implementation of the protective device for a pipeline laser cutting machine provided by this utility model, the shielding member is fitted with a first protective sleeve at both ends, and the hardness of the first protective sleeve is less than the hardness of the inner wall of the pipeline.
[0016] In one possible implementation of the protective device for a pipeline laser cutting machine provided by this utility model, the connecting member is a flexible member, and the hardness of the outer side of the flexible member is less than the hardness of the inner wall of the pipeline.

[0018] The beneficial effects of the protective device for a pipeline laser cutting machine provided by this utility model are as follows: Compared with the prior art, the protective device for a pipeline laser cutting machine provided by this utility model, through the fixed frame and connecting parts that extend into the pipeline, pulls the shielding part set in the pipeline, so that it will not move forward with the pipeline; and the projection of the pipeline's central axis in any direction perpendicular to the length of the pipeline falls within the projection range of the shielding part, so that the shielding part can always block the laser when the laser cutting machine moves around the pipeline, avoiding the situation of laser beams hitting each other.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0028] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0029] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0032] Please refer to the following: Figures 1 to 3 The protective device for a pipeline laser cutting machine provided by this utility model will now be described.
[0033] It should be noted that the protective device for a pipeline laser cutting machine provided by this utility model is suitable for pipeline production lines. The aforementioned production line processes continuous steel plates through a series of shaping processes to form the required shape, while retaining a weld gap of a certain width. Then, through welding by welding equipment and shaping by shaping equipment, a complete pipeline 40 is formed. Finally, the complete pipeline 40 is cut to the required length by a laser cutting machine. During cutting, the laser cutting machine moves forward synchronously with the pipeline 40 and around the pipeline 40, always facing the central axis of the pipeline 40, and automatically resets after completing one cut, repeating this process.
[0034] The protective device for the pipeline laser cutting machine includes a fixed frame 10, a shielding member 20, and a connecting member 30. The fixed frame 10 is fixedly installed, with one end extending into the pipeline 40 from the weld seam. The shielding member 20 is installed inside the pipeline 40, between two laser cutting machines. The projection of the central axis of the pipeline 40 in any direction perpendicular to the length of the pipeline 40 falls within the projection range of the shielding member 20, which is used to shield the laser. One end of the connecting member 30 is connected to the fixed frame 10, and the other end is connected to the shielding member 20.
[0035] Specifically, the fixing frame 10 is located upstream of the welding equipment in the production line and is fixedly connected to external equipment or the ground. At this time, the top of the pipe 40 has a welding gap of a certain width, and a plate-like component is provided on the fixing frame 10 to extend into the pipe 40 from the welding gap.
[0036] The shielding component 20 is made of high-temperature resistant material. The length of the shielding component 20 is greater than the distance that the laser cutting machine moves along the length of the pipe 40 during one cutting process, so as to block the laser throughout the process.
[0037] The beneficial effects of the protective device for a pipeline laser cutting machine provided in this embodiment of the present invention are as follows: Compared with the prior art, the protective device for a pipeline laser cutting machine provided in this embodiment of the present invention, through the fixed frame 10 and the connecting piece 30 extending into the pipeline 40, pulls the shielding piece 20 provided in the pipeline 40, so that it will not move forward with the pipeline 40; and the projection of the central axis of the pipeline 40 in any direction perpendicular to the length direction of the pipeline 40 falls within the projection range of the shielding piece 20, so that the shielding piece 20 can always block the laser when the laser cutting machine moves around the pipeline 40, thus avoiding the situation of laser beams hitting each other.
[0038] like Figure 1 and Figure 3 As shown, in a specific embodiment of the protective device for a pipeline laser cutting machine provided in this utility model, the shielding member 20 has a columnar structure.
[0039] Specifically, such as Figure 1 and Figure 3 As shown in the embodiment of the protective device for a pipeline laser cutting machine provided in this utility model, the shielding member 20 has a circular or polygonal cross section perpendicular to the axis, so as to block the oncoming laser when cutting the pipeline 40.
[0040] like Figure 1 and Figure 3As shown in the embodiment of the protective device for a pipeline laser cutting machine provided in this utility model, the shielding member 20 is a continuously variable diameter columnar structure with a large diameter end and a small diameter end. The small diameter end faces the fixing frame 10 and is connected to the connecting member 30. This allows the shielding member 20 to automatically insert into the pipeline 40 initially.
[0041] Furthermore, the end edge of the shield 20 is chamfered to facilitate automatic insertion into the pipe 40.
[0042] like Figure 3 As shown, in a specific embodiment of the protective device for a pipeline laser cutting machine provided in this utility model embodiment, the shielding member 20 is fitted with a first protective sleeve 21 at both ends, and the hardness of the first protective sleeve 21 is less than the hardness of the inner wall of the pipeline 40.
[0043] Specifically, the first sheath 21 only covers the corner of the shield 20 that contacts the pipe 40, in order to save material.
[0044] The first sheath 21 is made of wear-resistant materials such as wear-resistant rubber, polytetrafluoroethylene, and wear-resistant plastic to prevent the shielding part 20 from scratching the inner wall of the pipe 40.
[0045] like Figure 1 and Figure 3 As shown in the embodiment of the protective device for a pipeline laser cutting machine provided in this utility model, the connector 30 is a flexible component. The hardness of the outer side of the flexible component is less than the hardness of the inner wall of the pipeline 40, so as to avoid scratching the inner wall of the pipeline 40. The flexible component and the fixing frame 10 are fixedly connected together by binding, bolt fixing or welding.
[0046] like Figure 1 and Figure 3 As shown, in a specific embodiment of the protective device for a pipeline laser cutting machine provided in this utility model, the connector 30 includes a load-bearing inner core 31 and a second sheath 32. The second sheath 32 is sleeved on the outside of the load-bearing inner core 31 and has a hardness less than that of the inner wall of the pipeline 40.
[0047] It should be noted that the load-bearing inner core 31 is made of existing tensile ropes such as steel wire rope and fiber rope, which is used to ensure structural strength and prevent breakage; the second sheath 32, which is sleeved on the outside of the load-bearing inner core 31, is made of wear-resistant materials such as wear-resistant rubber, polytetrafluoroethylene, and wear-resistant plastic, which is used to provide protection for the load-bearing inner core 31 or to prevent scratches on the inner wall of the pipe 40.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
