[0043] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0044] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0045] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0046] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0047] The present application is further described below with reference to the accompanying drawings:

[0048] like Figures 1 to 11 As shown, the present application provides a method for cutting and welding a metal profile component, comprising the following steps.

[0049] The profile components are encoded, and a processing plan is designed separately for each profile component. The code and the processing plan are matched, and then the processing plan is uploaded to the processing equipment. The code can be in the form of digital code, QR code, barcode, etc., which is mainly used to identify and distinguish profile components.

[0050] The profile component is loaded and fixed, and the processing equipment identifies the code on the profile component and obtains the corresponding processing plan, wherein the processing plan includes the size, shape, loading status, processing direction switching sequence, cutting sequence in each processing direction, etc. of the profile component. The processing equipment performs processing according to the processing plan and can obtain a finished profile component that meets the design.

[0051] The processing equipment uses laser to cut and mark 6 the profile components sequentially or synchronously along the same processing direction. The profile components are cut into suitable shapes and parts by laser, and are marked 6 at specific positions by laser, which can be easily assembled and combined, reducing the difficulty of building the frame 1. The marks 6 generated by the laser are not easily erased and worn accidentally, and can be effectively maintained until the frame 1 is built. Due to the controllability of the laser, the marks 6 generated by the laser have better accuracy than traditional manual marking and can produce more styles, thereby meeting customized production and processing needs.

[0052] The profile component is turned over, and the processing equipment performs cutting and marking 6 again until the processing plan is completed. For parts with more complex structure and marks 6 across different sides of the profile component, they can be processed and formed through this step.

[0053] Cut the profile components, check the appearance of the profile components, and classify and store the qualified profile components. In actual operation, the profile components can be classified and stored according to their size, assembly area, functional role, etc., so as to facilitate their use when the rack 1 is built later.

[0054] Pre-assemble and fix the profile components according to the cutting structure and the mark 6 position on the profile components, and then weld the connecting positions between the profile components. When designing the processing plan for the profile components, an assembly plan can be designed according to the cutting structure and the mark 6 position on the profile components, and the assembly position and assembly method of the profile components can be identified by comparing the codes, thereby improving the assembly efficiency.

[0055] In some embodiments, when the processing equipment processes the profile component, a single cutting head can be used. The profile component can be cut and marked 6 in sequence by adjusting the output power of the laser emitted by the cutting head. This can reduce the cost of the processing equipment, reduce the volume of the processing equipment, and meet the production and processing of small batches of profile components. In addition, when the single cutting head switches between cutting and marking 6, it can also help the processing equipment to cool down and reduce the load, increase the upper limit of the continuous operation time of the processing equipment, and improve the operating life of the processing equipment.

[0056] It is worth noting that when the processing equipment is a single cutting head, the cutting and marking 6 sequence of the cutting head and the adjustment timing of the laser output power must also be considered when designing the processing plan for the profile component to ensure that the cutting and marking 6 can be carried out smoothly.

[0057] In some embodiments, when the processing equipment processes the profile component, multiple cutting heads are used to synchronously cut and mark the profile component by setting different laser output powers 6, wherein the high-power cutting head can cut the profile component, and the low-power cutting head can mark the profile component 6, and the two are performed synchronously, which has the characteristics of high processing efficiency and can meet the production and processing of large quantities of profile components.

[0058] In some embodiments, when the processing equipment processes the profile component, multiple cutting heads are used to synchronously cut and mark the profile component by setting different laser output powers 6, wherein the power of the cutting head can be adjusted between high power and low power. When the cutting head is adjusted to high power, the profile component can be cut, and when the cutting head is adjusted to low power, the profile component can be marked 6. The two are performed synchronously, which has the characteristics of high processing efficiency and can meet the production and processing of large quantities of profile components. In addition, since the power of the cutting head can be adjusted, the power size can be interchanged after the cutting head has been processed for a period of time to extend the service life of the cutting head and reduce processing costs.

[0059] It is worth noting that when the processing equipment has multiple cutting heads, the structural interference and laser interference when different cutting heads are in action must be considered when designing the processing plan for the profile component to avoid blocking each other and affecting the cutting and marking process or even causing damage to the cutting head.

[0060] In some embodiments, the cutting process of the profile component by the processing equipment includes cross-cutting of dimensional modeling cutting and combined structure cutting. Since the dimensional modeling and the combined structure may be related during the cutting process, and completing the cutting at one time will result in a larger movement span of the cutting head, which will reduce efficiency when returning to the original position. The purpose of the cross-cutting process is to reduce the sequence weight of the structure, giving the highest priority to processing efficiency and processing stability, allowing the cutting head to cut with the optimal activity route and cutting action, ensuring that the dimensional modeling cutting and the combined structure cutting can be completed smoothly.

[0061] like Figure 2 , 8 In the embodiments shown in 9, the combined structure is suitable for positioning and fixing the profile components, and the combined structure includes a connecting groove 3, a connecting edge 2, a positioning hole 4 and a positioning block 5. The shapes of the connecting groove 3, the connecting edge 2, the positioning hole 4 and the positioning block 5 can be designed according to actual conditions.

[0062] Since the processing equipment cuts from one direction, it is difficult to shape a part of the combined structure from one direction. Therefore, the cutting of this part of the combined structure is suitable for forming by turning over the profile component through multiple cutting.

[0063] like Figure 4 ,5 In the embodiment shown in 6, the mark 6 processed by the processing equipment on the profile component is composed of a single or multiple positioning lines 61, and the positioning lines 61 are at least suitable for locating the corner positions of the profile component and / or the edge positions of the profile component. By changing the combination and arrangement of the positioning lines 61 and utilizing the visual effect formed by the combination of single or multiple positioning lines 61, the construction personnel can be effectively guided to coordinate and position the profile components, thereby improving the assembly efficiency of the frame 1 and reducing the assembly difficulty.

[0064] Among them, due to the controllability of the laser, the positioning line 61 can be processed into a solid line, a dotted line, a dotted line, etc. according to needs.

[0065] like Fig.10 In the embodiment shown, the processing equipment is suitable for processing positioning lines 61 of different lengths, widths and depths by adjusting the output power and output time of the laser to distinguish the combination of profile components. By making full use of the controllability of the laser, the shape of the positioning line 61 can be further increased. Combined with the selection of the line type of the positioning line 61 in the above embodiment, a rich marking 6 scheme can be obtained, which can be applied to the assembly and positioning process of various non-standard customized racks 1.

[0066] It can be understood that, in combination with the above-mentioned embodiments, when designing a processing plan, assembly rules can be established according to the line type and shape of the positioning line 61, and an operation manual can be made to facilitate operators to refer to the established assembly rules and identify the assembly form between profile components through the positioning line 61. After becoming proficient, the assembly efficiency can be greatly improved and the assembly error rate can be reduced.

[0067] like Figures 1 to 11 As shown, the present application provides a metal profile member cutting design method, comprising the following steps.

[0068] A pre-assembled model of the profile component is established in the 3D software, and the 3D software may be the commonly used industrial 3D design software on the market.

[0069] The size, shape and cutting plan of each profile component is designed according to the pre-assembled model. The pre-assembled model is first cut and separated into independent processable groove components, and the connection between the profile components can be ignored.

[0070] A combined structure that cooperates with each other is designed at the combining position of the profile components. Specifically, a connecting edge 2 or a positioning block 5 can be formed on the profile component, and a connecting groove 3 or a positioning hole 4 can be dug out on the profile component according to the specific situation of the combining position of the profile component, to ensure that the profile components can be preliminarily combined before welding and have sufficient stability to facilitate subsequent welding processes.

[0071] At the contact position of the two profile components, a mark 6 is set on the surface of the other profile component along the edge of one profile component, which is suitable for positioning the mark 6 between two independently connected profile components.

[0072] At the contact position of multiple profile components, a continuous mark 6 is set up on the surface of other profile components along the edge of one profile component, which is suitable for positioning the mark 6 between multiple combined and connected profile components, and tries to ensure that each profile component can be guided and assembled through the mark 6.

[0073] The designed profile components are exported separately as processing plans, which include the size, shape, loading status, processing direction switching sequence, cutting sequence in each processing direction, etc.

[0074] In some embodiments, the combined structure includes a connecting edge 2 and a connecting groove 3, and the connecting edge 2 and the connecting groove 3 are suitable for being assembled with each other. The connecting edge 2 and the connecting groove 3 can increase the contact area between the profile components, thereby increasing the welding range, and finally ensuring the connection strength between the profile components. Figures 1 to 3 As shown, the combined structure is suitable for connecting the profile components of the base 11 of the frame 1 to improve the overall stability and support of the frame 1.

[0075] like Figure 2 and 3 In the illustrated embodiment, the connecting edge 2 and the connecting groove 3 are designed to restrict each other in directions other than the splicing direction. This design enables the profile components to be directly positioned and combined through the connecting edge 2 and the connecting groove 3, thereby reducing the difficulty of welding and improving assembly efficiency.

[0076] like Figure 4 In the embodiment shown, a mark 6 is set on the edge of the joint position of the connecting edge 2 and the connecting groove 3. If the processing difficulty of the connecting edge 2 or the connecting groove 3 is relatively large, this method can be used to position the connection between the profile components to reduce the difficulty of assembly. The mark 6 is suitable for being designed on another profile component in the form of an extension line along the edge of the profile component in the form of a single positioning line 61. During assembly, positioning can be completed by simply joining the edge of the profile component with the positioning line 61.

[0077] like Figure 5 and 7 In the illustrated embodiment, the combined structure includes a positioning hole 4 and a positioning block 5, and the positioning hole 4 and the positioning block 5 are suitable for combining with each other. The positioning block 5 is established in the contact surface of the profile component. The design of the positioning block 5 and the positioning hole 4 can improve the positioning stability between the profile components and reduce the difficulty of welding.

[0078] It is understandable that the shapes of the positioning blocks 5 and positioning holes 4 at different positions can be selected in different styles, such as cones, cuboids, cylinders, etc., to reduce the probability of mismatching of profile components and improve the smoothness of profile component assembly operations.

[0079] like Figure 5 , 6 In the embodiments shown in Figures 8 and 9, at least one positioning hole 4 is opened in the bonding surface formed by a single or multiple profile components, and corresponding positioning blocks 5 are added to the profile components arranged on the bonding surface. The more positioning blocks 5 and positioning holes 4 there are, the more stable the arrangement of the profile components on the bonding surface will be, but it may increase the difficulty of processing.

[0080] like Figure 8 In the illustrated embodiment, when the positioning block 5 and the profile member have the same thickness, the positioning block 5 is suitable for being cut in one direction to form the shape at one time.

[0081] like Fig. 9 In the illustrated embodiment, when the thickness of the positioning block 5 is less than the thickness of the profile component, the cutting of the positioning block 5 is suitable for cutting and shaping multiple times in multiple directions by turning over the profile component.

[0082] In some embodiments, the mark 6 is composed of a single or multiple positioning lines 61. By changing the combination and arrangement of the positioning lines 61 and utilizing the visual effect formed by the single or multiple positioning lines 61, the construction personnel can be effectively guided to coordinate and position the profile components, thereby improving the assembly efficiency of the frame 1 and reducing the difficulty of assembly.

[0083] This method is particularly suitable for connecting the profile member of the support member 12 of the frame 1 and the profile member of the base 11 to improve the installation accuracy of the lifting support member 12.

[0084] like Figure 2 In the embodiment shown, the positioning line 61 can also assist the connecting edge 2 and the connecting groove 3 in positioning the profile component. For example, one end of the profile component is positioned and connected to other profile components through the connecting edge 2 and the connecting groove 3, and the other end of the profile component can be positioned and connected to other profile components in the form of the positioning line 61, thereby realizing a variety of positioning forms.

[0085] like Figure 5 In the illustrated embodiment, the positioning line 61 can be established in the form of a dotted line or a solid line along the entire edge of the profile component, which has the advantage of enabling the profile component to obtain a relatively complete positioning guide indication, thereby effectively reducing the difficulty of installation.

[0086] like Figure 6In the embodiment shown, under the premise of ensuring that the mark 6 formed by combining the positioning lines 61 can be visually clearly observed, the coverage area of ​​the positioning lines 61 can be shortened as much as possible, and the positioning lines 61 are preferentially established in the form of dotted or solid lines along the corners and edges of the profile components, and across the joints of different profile components, and combined with the positioning blocks 5 and the positioning holes 4, the profile components are helped to be positioned. Since the laser mark 6 may affect the structural stability of the profile components, reducing the coverage area of ​​the positioning lines 61 can ensure the structural strength of the profile components.

[0087] like Figure 6 In the illustrated embodiment, if the accessory 13 (refer to the triangular component in the figure) installed on the base 11 is difficult to distinguish between the front and back, the installation positions on the front and back sides of the accessory 13 can be distinguished by drawing solid lines and dotted lines respectively to guide the operator to install.

[0088] like Fig.10 In the illustrated embodiment, the positioning line 61 is suitable for setting different lengths, widths and depths to distinguish the combination of profile components. If the length of the accessory 13 (refer to the rectangular component in the figure) installed on the base 11 is much longer than the width, it is possible to set wider positioning lines 61 at both ends of the installation position of the accessory 13, and set multiple shorter solid or dotted positioning lines 61 along the side edges of the installation position of the accessory 13 to help effectively position the accessory 13.

[0089] It is understandable that the combination structure shown in the above embodiment and the application of mark 6 are only part of the application methods, which are difficult to list completely. In actual use, more varied application methods can be used according to design ideas and specific scenarios.

[0090] like Figure 5 , 6 In the embodiments shown in Figures 7, 10 and 11, the mark 6 is set in the contact surface of adjacent profile components. When the profile components are combined, the mark 6 can be completely covered by the profile components, playing a hiding role, increasing the aesthetics and integrity.

[0091] The above describes the basic principles, main features and advantages of the present application. Technical personnel in this industry should understand that the present application is not limited to the above embodiments. The above embodiments and the specification only describe the principles of the present application. Without departing from the spirit and scope of the present application, the present application will also have various changes and improvements. These changes and improvements all fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
