Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a profile component, a wall and a laser room. Background Art

[0002] Laser welding or laser cutting, as a high-precision and efficient processing method with distinct advantages such as concentrated energy, fast processing speed, small heat-affected zone, minimal deformation, and low spatter, has been widely used in various industries. However, the high-intensity energy of lasers can easily cause extremely intense photochemical, photothermal, photodynamic, photoablation, and light-wave electromagnetic interactions with biological tissues, causing serious damage. Therefore, in laser applications, especially high-power laser applications, it is particularly important to build a laser protection room with good light shielding.

[0003] Laser room walls are typically assembled from aluminum or steel profiles, processed into defined cross-sections through rolling, extrusion, or casting. These profiles possess specific mechanical properties and are available in a variety of sizes and for a wide range of applications. However, most current profiles require multiple bending or casting steps, making them inconvenient and costly to manufacture. Conventional processing methods may also be limited by the inability to meet assembly precision requirements, or they may be difficult to maintain due to deformation. Furthermore, achieving complete light shielding after assembly is difficult, and may even require post-processing methods such as sealing strips. Therefore, it is crucial to design a profile that is economical, easy to process, easy to maintain, and easy to transport, yet easy to assemble and provide excellent light shielding properties.

[0058] Example 2:

[0059] The difference between the embodiment and embodiment 1 is that Figure 1 、 5 As shown in Figures 6 and 7, the profile unit also includes a plurality of second connecting profiles 2, which are used to connect with the first connecting profile 1 at the corners so that the profile unit can be spliced into the desired shape. The second connecting profile 2 includes a second splicing portion 211 and a second overlapping portion 221; the second splicing portion 211 and the second overlapping portion 221 form a second "P"-shaped interface at the overlapping portion, and the second "P"-shaped interface is staggered with the remaining adjacent profile units, such as the first "P"-shaped interface in the first connecting profile, to form a splicing; the second overlapping portion 221 is used to connect with the remaining adjacent profiles, such as the overlapping portion 121 of the first connecting profile 1, so that the second connecting profile 2 forms a fixed connection with the remaining adjacent profiles, such as the first connecting profile 1.

[0060] Furthermore, if Figure 5 and Figure 6 As shown, the second connecting profile 2 includes:

[0061] The second main mold plate 21 is bent to form a first angle, which is denoted as θ1, where 0<θ1<180°; both free ends of the second main mold plate 21 are bent toward the inner side of the second main mold plate 21 to form a second splicing portion 211; and a second mold plate groove (not shown in the figure) is formed by the two sides of the first angle θ1 and the two second splicing portions 211.

[0062] The second sub-form plate 22 is bent to form a second angle, which is denoted as θ2, 0<θ2<180°, and θ1+θ2=180°; the two free ends of the second sub-form plate 22 are bent toward the same side of the second sub-form plate 22 to form a second overlapping portion 221, and the two second overlapping portions 221 are vertically inserted into the groove of the second form plate and abut against the corresponding second splicing portion; so that the cross section of the second splicing portion 211 and the second overlapping portion 221 at the overlapping portion is "P"-shaped to form a second "P"-shaped interface, such as Figure 6 Preferably, θ1=θ2=90°.

[0063] At this time, a second cavity (not shown in the figure) is formed by the second main mold plate 21, the second sub-mold plate 22, and two second overlapping parts 221 inserted into the grooves of the second mold plate; more specifically, the second cavity (not shown in the figure) is formed by the two sides of the first angle θ1 in the second main mold plate 21 and the two sides of the second angle θ2 in the second sub-mold plate 22 overlapping each other.

[0064] At the same time, the second connecting portion 223 is provided on the second overlapping portion 221, and is fixedly connected to the connecting portion of the adjacent profile unit through the second connecting portion 223, so that the splicing structure of the second connected profile 2 and the adjacent first profile 11 is more stable. The connection method of the adjacent first profiles 11 can be selected from welding, bonding, screw / bolt connection, etc.

[0065] The second rib 23 is arranged in the second mold cavity and connected to the inner side of the second main mold plate 21 and the second auxiliary mold plate 22 to improve the overall strength of the second connecting profile.

Specifically, the outer side surface of the second splicing portion 211 is brought into close contact with the first overlapping portion 121, and the outer side surface of the first splicing portion 111 is brought into close contact with the second overlapping portion 221, thereby achieving staggered cooperation between the first "P"-shaped interface and the second "P"-shaped interface. When the first connecting profile 1 and the second connecting profile 2 are well matched, the second connecting portion 223 is fixedly connected to the corresponding first connecting portion 123, so that the first connecting profile 1 and the second connecting profile 2 form a stable connection. The second connecting profile 2 allows the profile unit to complete the splicing of the profile assembly corners while ensuring light tightness.

[0069] Example 3:

[0070] The difference between the embodiment and embodiment 1 or 2 is only that, Figure 1 、 8As shown in Figures 9 and 9, the profile unit further includes a plurality of third connecting profiles 3. The third connecting profiles 3 have a bending angle θ3. By changing the angle of the bending angle, splicing between connecting profiles of various required installation angles can be achieved. The third connecting profile 3 includes a third splicing portion 311, a third overlapping portion 321, and a bending angle.

The bending angle is provided in the middle of the third connecting profile 3, and the third splicing portion and the third overlapping portion form a third "P"-shaped interface at the overlapping portion. By staggered cooperation of the third "P"-shaped interface with the first or second "P"-shaped interface or the adjacent third "P"-shaped interface, the third connecting profile 3 can be spliced with the first or second connecting profile or the adjacent third connecting profile 3, and then the third connecting part 323 is fixedly connected with the corresponding first connecting part 123 or the corresponding second connecting part 223 to achieve the fixation of the third connecting profile 3 with the first or second connecting profile or the adjacent third connecting profile 3.

[0071] Furthermore, if Figure 8 and Figure 9 As shown, the third connecting profile 3 includes:

[0072] The third main mold plate 31, the two ends of the third main mold plate 31 are bent toward the same side of the third main mold plate 31 to form a third splicing portion 311; the main part of the third main mold plate 31 can be bent arbitrarily to form a first bending angle θ3, and the first bending angle θ3 and the third splicing portion 311 are arranged on different sides of the third main mold plate 31; a third mold plate groove (not marked in the figure) is formed between the two third splicing portions 311.

Figure 10 As shown in FIG. 90°<θ3=θ4<180°.

[0074] At this time, a third mold cavity (not shown in the figure) is formed by the third main mold plate 31, the third auxiliary mold plate 32 and the two third splicing parts 321 inserted into the grooves of the third mold plate.

[0075] At the same time, the third connecting portion 323 on the third overlapping portion 321 does not overlap with the projection of the third splicing portion 311 on the third overlapping portion 321. The third connecting portion 323 is fixedly connected to its adjacent first connecting portion 123 or second connecting portion 223, or adjacent third connecting portion 323, to further stabilize the splicing structure of the third connecting profile and the gas arbitrary connecting profile. The other arbitrary connecting profiles herein include, but are not limited to, the first connecting profile, the second connecting profile, and the third connecting profile having a "P"-shaped interface.

[0076] The third rib 33 is disposed within the third mold cavity and connected to the inner sides of the third main mold plate 31 and the third auxiliary mold plate 32 to enhance the overall strength of the third connected profile. Preferably, the third rib 33 is connected to the two edges of the third main mold plate 31 at the first bend angle θ3 and to the two edges of the third auxiliary mold plate 32 at the second bend angle θ4.

[0078] When the third connecting profile 3 needs to be spliced with the first, second or third connecting profile, the third "P"-shaped interface is staggered with the "P"-shaped interface of the other adjacent connecting profiles, and then the third connecting portion 323 is connected and fixed with the connecting portion of the other connecting profiles. In this embodiment, the splicing of the third connecting profile 3 and the first connecting profile 1 is taken as an example for detailed description. Figure 10 As shown:

[0079] The outer side surface of the splicing portion 311 of the third connecting profile 3 is pressed against one side of the overlapping portion 121 of the adjacent first connecting profile 1, and the outer side surface of the first splicing portion 111 is pressed against one side of the third overlapping portion 321, thereby forming a staggered fit between the first "P"-shaped interface and the third "P"-shaped interface. After the "P"-shaped interfaces are staggered, the third connecting portion 323 and the first connecting portion 123 are connected in a fixed connection manner, thereby fixing the splicing of the first connecting profile 1 and the third connecting profile 3.

[0084] In summary, the present application forms a "P"-shaped interface by bending and fitting the template in the connecting profile multiple times. On the one hand, this increases the edge strength of the connecting profile. On the other hand, by fitting the "P"-shaped staggered connection between the connecting profiles, the shading function between the profile wall can be achieved without the need for a sealing strip. Moreover, due to the connecting function of the connecting part, the stability of the spliced profile assembly is also increased. At the same time, since the processing precision requirements for the "P"-shaped structure are low in this application, processing and transportation are also more convenient. It can be seen that the profile assembly of this application has the characteristics of simple processing, low cost, easy protection and assembly, strong stability and excellent shading performance.
