Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of mechanical manufacturing, and particularly, to a production method and product of a metal cylindrical shell. BACKGROUND

[0002] In the existing product manufacturing process, for a cylindrical shell, especially a metal cylindrical shell, an extrusion method (i.e., using a stretching die) is usually adopted to produce. Then, a computer number control (CNC) technology is generally adopted to perform secondary processing on the shell, the inside of the shell, and the like, so as to obtain a final required shell. However, this production process often has certain limitations on the product. For example, the shapes of the shells that can be produced by the extrusion method are usually limited. In addition, because the space inside the shell is usually limited, the shapes that can be processed in the cavity are affected. This production method not only consumes a long production time, but also increases the production cost.

[0003] In addition, the inventors have found that the production process design of the existing product is usually completed by a designer. The rationality of the process design depends largely on the working experience and knowledge reserve of the designer. During the design process, the process is often repeatedly modified and adjusted. This increases the process design time of the product and affects the production efficiency of the product. SUMMARY

[0004] This part of the disclosure is used to introduce the concepts in a brief form, which will be described in detail in the specific embodiments part. This part of the disclosure is not intended to identify the key features or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions. Some embodiments of the present disclosure propose a production method and product of a metal cylindrical shell to solve one or more of the technical problems mentioned in the background part.

[0005] In a first aspect, some embodiments of the present disclosure provide a production method of a metal cylindrical shell, comprising: splitting a metal cylindrical shell of a product according to the structure of the product to obtain a plurality of component parts, wherein the plurality of component parts comprises a shell upper cover, a shell lower cover, a first metal sheet, and a second metal sheet; producing the plurality of component parts by stamping a metal sheet; and welding and assembling the plurality of component parts according to the positional relationship between the component parts to obtain the metal cylindrical shell, wherein the first metal sheet and the second metal sheet are located inside the shell.

[0006] In some embodiments, the shell upper cover is provided with a through window at a central position, and a protrusion is formed around the window on the outer surface of the shell upper cover.

[0007] In some embodiments, the welding assembly of the plurality of components according to the positional relationship between the components comprises: setting welding point marks on the first metal sheet and the second metal sheet; and welding at positions indicated by the welding point marks to fix the first metal sheet to the inner side of the upper cover of the shell and fix the second metal sheet to the inner side of the lower cover of the shell.

[0008] In some embodiments, the inner part of the metal cylindrical shell further comprises a support frame, which comprises two upper frames and two lower frames; the two upper frames are adapted to the inner side of the upper cover of the shell and are respectively located on the two sides of the first metal sheet; and the two lower frames are adapted to the inner side of the lower cover of the shell and are respectively located on the two sides of the second metal sheet.

[0009] In some embodiments, the material of the support frame is plastic, which is produced by injection molding; and the two upper frames are fixed to the upper cover of the shell and the two lower frames are fixed to the lower cover of the shell by adhesion.

[0010] In some embodiments, the welding assembly of the plurality of components according to the positional relationship between the components comprises: fixing the two sides of the upper cover of the shell to the two sides of the lower cover of the shell by laser welding under the condition that the first metal sheet and the second metal sheet are respectively fixed to the upper cover of the shell and the lower cover of the shell; fixing the support frame to the metal cylindrical shell by adhesion under the condition that the upper cover of the shell and the lower cover of the shell are fixed; and polishing the welding seams on the two sides and spraying the shell after polishing.

[0011] In some embodiments, the metal cylindrical shell further comprises a cover plate at the position corresponding to the window, and the material of the cover plate is plastic, which is produced by numerical control machining.

[0012] In some embodiments, the materials of the upper cover of the shell and the lower cover of the shell are 6-series aluminum, and the materials of the first metal sheet and the second metal sheet are stainless steel or metal aluminum.

[0013] In some embodiments, the metal cylindrical shell of the product is split into a plurality of components according to the structure of the product, which comprises: inputting design scheme information of the product into an artificial intelligence chip connected in communication, and obtaining a reference production process of the product by analyzing the artificial intelligence chip, wherein the artificial intelligence chip is used to analyze the production methods that can be adopted according to the input product information, the design scheme information is used to represent the attribute information of each part of the product, and the reference production process is used to represent the production method of each part of the product; and the metal cylindrical shell of the product is split according to the reference production process of the product to determine the plurality of components.

[0014] In a second aspect, some embodiments of the present disclosure provide a product, comprising: a metal cylindrical shell obtained by the production method as described in any implementation of the first aspect; and a control component installed in the interior of the metal cylindrical shell.

[0015] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: the production method of the metal cylindrical shell of some embodiments of the present disclosure can reduce the process design limitations of the product, thereby enriching the modeling and diversity of the product. Specifically, as described in the background section, the existing production methods of the metal cylindrical shell usually have design limitations. For example, the shape of the extruded shell is usually a smooth curve without complex structures. In addition, numerical control machining in the shell not only takes a long time, but also has limitations on the shapes that can be machined.

[0016] Therefore, the production method of the metal cylindrical shell of some embodiments of the present disclosure can split the metal cylindrical shell of the product according to the structure of the product. Thus, each component part can be produced by stamping or other non-extrusion methods. Then, the metal cylindrical shell can be obtained by welding assembly. That is, the whole metal cylindrical shell obtained by extrusion can be split into multiple component parts and reassembled by stamping. In this way, the limitations of the process design of the product can be reduced, and the modeling and diversity of the product can be enriched. In addition, since the metal cylindrical shell is split into multiple component parts, the structure inside the shell can be obtained by secondary machining of each component part before the shell is assembled. In this way, the limitations of the internal space of the shell can be avoided, thereby further reducing the limitations of the product design and reducing the processing difficulty and processing time.

[0028] It should be noted that the terms "one", "multiple" mentioned in the present disclosure are illustrative and not restrictive, and those skilled in the art should understand that unless otherwise explicitly stated in the context, it should be understood as "one or more".

[0029] The names of the messages or information exchanged between the devices in the embodiments of the present disclosure are only for illustrative purposes and are not intended to limit the scope of the messages or information.

[0030] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0031] Reference is made to Figure 1 , which shows a flowchart 100 of some embodiments of a production method of the metal cylindrical shell according to the present disclosure. The production method can include the following steps:

[0032] Step 101, according to the structure of the product, the metal cylindrical shell of the product is disassembled to obtain a plurality of component parts.

[0033] In the present embodiment, the metal cylindrical shell of the product can be first split according to the structure of the product, such as the material, shape, etc. of each component, so as to obtain a plurality of component parts. For example Figure 5 The metal cylindrical shell shown in the figure can be split into Figure 2A and 2B the shell upper cover 11, the shell lower cover 12, the first metal sheet 21 and the second metal sheet 22, etc. Here, the materials of the plurality of component parts can be the same or different.

[0034] As can be seen from Figure 5 , the first metal sheet 21 and the second metal sheet 22 can be located inside the shell. As an example, the first metal sheet 21 can be located on the inner side of the shell upper cover 11. The second metal sheet 22 can be located on the inner side of the shell lower cover 12.

[0035] It should be noted that the above splitting process can be determined according to the experience of the producer. For example, according to the material of different positions, or the production method or alternative solution that can be adopted, etc. In some embodiments, the production splitting of the product can also be realized by an artificial intelligence chip (AI chip).

[0036] Specifically, the design scheme information of the product can be input into the artificially intelligent chip connected in communication. Further, the reference production process of the product can be analyzed by the artificially intelligent chip. In this way, according to the reference production process of the product, the metal cylindrical shell of the product can be split to determine a plurality of component parts. Among them, the artificially intelligent chip can be used to analyze the production method that can be adopted according to the input product information. Here, the design scheme information is generally used to represent the attribute information of each part of the product, such as size, shape, material, process requirement, etc. The reference production process is generally used to represent the production method of each part of the product.

[0037] It should be noted that the artificially intelligent chip is also commonly referred to as an AI accelerator or a computing card, i.e. a module specially used to process a large amount of computing tasks in artificial intelligence applications. Here, the artificially intelligent chip usually carries a machine learning model. The machine learning model is generally trained by a set of training samples. Among them, the machine learning model can be various existing learning models created based on machine learning technology. The machine learning model can have various existing neural network structures (such as DenseBox, VGGNet, ResNet, SegNet, CNN, DNN, etc.).

[0038] As an example, the machine learning model can be obtained by performing the following training steps on a set of training samples: selecting at least one training sample from the set of training samples, wherein the training sample includes sample design scheme information and sample production process of a sample product; inputting the sample design scheme information in the selected training sample into an initial machine learning model to obtain a reference production process of the sample product; comparing and analyzing the reference production process of each sample product in the selected at least one training sample with the corresponding sample production process; determining a prediction accuracy of the initial machine learning model according to the comparison result, and determining whether the prediction accuracy is greater than a preset accuracy threshold; in response to determining that the accuracy is greater than the preset accuracy threshold, taking the initial machine learning model as the trained machine learning model; in response to determining that the accuracy is not greater than the preset accuracy threshold, adjusting the related parameters in the initial machine learning model; taking the adjusted machine learning model as the initial machine learning model, and reselecting the training sample from the set of training samples to perform the above training steps again. It can be understood that after the above training, the machine learning model can be used to represent the corresponding relationship between the design scheme information and the production process of the product.

[0039] For another example, the machine learning model can include a corresponding relationship table of the design scheme information and the production process of the product. The corresponding relationship table can be created by a person skilled in the art based on analysis of a large number of product designs and production processes. In this way, the design scheme information of the product can be compared with the design schemes of a plurality of products in the corresponding relationship table in turn. If the design scheme of a product in the corresponding relationship table matches (is the same or similar) the design scheme of the product, the production process of the matched product in the corresponding relationship table can be taken as the production process of the product.

[0040] In some embodiments, the artificial intelligence chip can be connected to other electronic devices in communication through, for example, a PCIE bus to receive or send information. The PCIE (peripheral component interconnect express) is generally a high-speed serial computer expansion bus standard. The artificial intelligence chip can use the received training data and / or test data to train and / or test the machine learning model stored thereon. In addition, the artificial intelligence chip can input the data to be analyzed, such as the design scheme information of the product, into the trained model to analyze using the model. It can be understood that by using the artificial intelligence chip to analyze and determine the production process of the product, the dependence on the work experience and knowledge reserve of the designer can be reduced or avoided, and the accuracy of the analysis result can be improved. This helps to reduce the number of repeated modifications and adjustments of the process in the production process, thereby shortening the time for designing the production process of the product.

[0041] Here, the artificial intelligence chip can include a storage component, at least one general-purpose execution component, and at least one special-purpose execution component. Here, the storage component can be a circuit or device capable of implementing an information storage function. For example, it can be a static random-access memory (SRAM), a random access memory (RAM), a memory stick, a secure digital memory card (SD card), or a flash memory card (TF card, also known as microSD), etc. One or more programs can be stored in the storage component.

[0042] In some embodiments, the general-purpose execution component can be used to receive data and send the data to the corresponding special-purpose execution component. As an example, the general-purpose execution component can include a programmable general-purpose computing graphics processor, such as an ARM (Advanced RISC Machine or Acorn RISC Machine) core, a 51 core, etc. The special-purpose execution component can be used to receive and process data sent by the general-purpose execution component. As an example, the special-purpose execution component can include an execution component dedicated to processing computationally intensive computing tasks in a machine learning model, which can include but is not limited to at least one of the following: a convolution engine, an activation data processor, a pooling data processor, a general-purpose data processor, and a parameter adjustment processor. The convolution engine can be used for data processing of the model convolution layer; the activation data processor is used for data processing of the model activation function layer; the pooling data processor is used for data processing of the model pooling layer; the general-purpose data processor is used for data processing of the model standardization layer; and the parameter adjustment processor can be used for back propagation calculation and adjustment of model parameters.

[0043] Optionally, in order to improve the analysis efficiency of the model, a plurality of (at least two) sub-models can be included in the above-mentioned machine learning model due to the variety of mechanical production methods and processes. Each sub-model can be used to analyze at least one production process. In this case, each special-purpose execution component can also correspond to each sub-model to process the computing tasks of the sub-model.

[0044] In some embodiments, the artificial intelligence chip can also include a data storage component for storing information related to various mechanical production methods, such as commonly used production methods, applicable scope and material, advantages and disadvantages, etc. Users can update and maintain the data therein. In this way, when new mechanical production data is available, the artificial intelligence chip can periodically update and train the machine learning model thereon. This can save the artificial training and updating of the model, and can effectively ensure the timely updating of the model, thereby further improving the accuracy of the analysis result and improving the production efficiency of the product. In addition, it is also helpful to expand the applicable scope of the machine learning model.

[0045] Step 102, producing a plurality of component parts by stamping the metal plate.

[0046] In some embodiments, the plurality of component parts can be produced by stamping the metal plate. As an example, the shell upper cover 11 and the shell lower cover 12 can be made of metal aluminum. The shape of the shell upper cover 11 can refer to Figure 2A . The shape of the shell lower cover 12 can refer to Figure 2B . The thickness of both can be set according to actual needs, such as 0.6 mm. From Figure 2A and 2B , it can be seen that the two sides and the bottom end of the shell upper cover 11 and the shell lower cover 12 form an arc shape bending inward. At the same time, the top end of the shell upper cover 11 and the shell lower cover 12 forms a stop edge bending inward. In addition, one side of the shell upper cover 11 and the shell lower cover 12 also forms a corresponding hole slot at a position close to the top end.

[0047] Further, as shown in Figure 5 , the shell upper cover 11 is provided with a through window K at the center position. The outer surface of the shell upper cover 11 can form a protrusion around the window K. It can be understood that the window K can be obtained at the same time in the process of stamping the shell upper cover 11. Such a protruding window generally cannot be obtained by extrusion. This not only can enrich the product modeling, but also can avoid or reduce secondary processing, thereby helping to reduce the production time.

[0048] In some embodiments, the first metal sheet 21 and the second metal sheet 22 can be made of stainless steel (such as SUS301) or metal aluminum. The thickness can also be set according to actual needs, such as 0.2 mm. The shape of the two metal sheets is also not limited here. As an example, the first metal sheet 21 can adopt the shape shown in Figure 3 .

[0049] Optionally, the first metal sheet 21 can also be provided with a through hole P matching the window K at the position corresponding to the window K, as shown in Figure 2A and 3 . The through hole P can realize circuit connection and the like. In addition, in order to improve the production efficiency of the product, the first metal sheet 21 and the second metal sheet 22 can have the same shape and size. According to actual production needs, the two metal sheets can also have different shapes and sizes.

[0050] Step 103, assembling the plurality of component parts according to the positional relationship between the component parts to obtain a metal cylindrical shell.

[0051] In some embodiments, the plurality of components can be assembled according to the positional relationship between the components to obtain the metal cylindrical shell. As shown in Figure 2A and 2B After the stamping of the components, assembly marks can be made on the components. Since the shell and the metal sheet are both made of metal, they can be fixed by welding, such as laser welding. As shown in Figure 3 Welding marks (such as dots in the figure) can be provided on the first metal sheet 21 and the second metal sheet 22. At this time, the first metal sheet 21 can be welded to the inner side of the upper cover 11 of the shell, and the second metal sheet 22 can be welded to the inner side of the lower cover 12 of the shell.

[0052] Here, after the first metal sheet 21 and the second metal sheet 22 are fixed to the upper cover 11 and the lower cover 12 of the shell, respectively, the two sides of the upper cover 11 can be fixed by welding to the two sides of the lower cover 12. That is, after the metal sheet is fixed to the corresponding shell component, the shell components can be welded to obtain a complete metal cylindrical shell. Then, the welds on both sides can be polished, and the shell after polishing can be sprayed. Compared with the traditional production method of extrusion and numerical control machining, the production process of first splitting and then welding assembly can greatly reduce the limitation on process design, and effectively reduce the production time and cost.

[0053] Specifically, the traditional stretching die generally has a short service life, and the product size often differs greatly due to changes in the size of the die. The stamping die provides better size control. The traditional product uses CNC process inside, which consumes more working hours, resulting in high cost. Especially for some special joint structures, it is often impossible to achieve due to the limitations of machining space, machining tooling and tools. The combination of stamping structure and laser welding provides a more feasible structure design application.

[0054] In addition, when the above metal cylindrical shell is used as an appearance part, the welding difficulty requirements are generally increased for aesthetic considerations. The main difficulty of welding is usually the control of the composition, stress and size of the weld. The advantage of laser welding is that it can more easily achieve the above indicators. In addition, the porosity, depression, sand eye of the weld, and the welding efficiency will directly affect the yield and cost of the final product. Here, the embodiments of the present disclosure also optimize the welding, polishing and subsequent surface treatment.

[0055] First, the material and welding process of the metal aluminum shell are optimized. During the production experiment, the inventors consider the stamping and welding process requirements and select 6 series aluminum material and the corresponding heat treatment process. The infrared laser is used at a specific wavelength, such as 1000 to 1100 nanometers (such as 1070 nanometers), to achieve continuous welding to achieve sufficient strength and appearance requirements. Among them, the 6 series aluminum alloy is an aluminum alloy with magnesium and silicon as the main alloying elements and with magnesium silicide phase as the strengthening phase, which belongs to heat-treatable aluminum alloy. This kind of aluminum alloy generally has medium strength, high corrosion resistance, no stress corrosion cracking tendency, good welding performance, unchanged corrosion performance in the welding area, good formability and process performance, and other advantages. Secondly, because the material state of the welding area changes, it will cause color difference after anodic oxidation. The embodiments of the present disclosure can achieve partial color to meet the appearance requirements through process optimization. Here, the process optimization can adjust the electrolyte composition and concentration, temperature, anodizing time and current density, and impurity content, etc. to control the color and thickness of the oxidation film, so as to achieve the purpose of controlling the color difference.

[0056] In some embodiments, in order to increase the firmness of the shell, a support frame is further arranged in the interior of the metal cylindrical shell. Here, the structure of the support frame is also not limited. As an example, as shown in Figure 4 , the support frame can include two upper frames and two lower frames. As shown in Figure 2A , the two upper frames Z1 can be adapted to the inner side of the shell upper cover 11 and are located on both sides of the first metal sheet 21 respectively. As shown in Figure 2B , the two lower frames Z2 can be adapted to the inner side of the shell lower cover 12 and are located on both sides of the second metal sheet 22 respectively. In this way, the deformation of the shell can be reduced.

[0057] Further, in order to reduce the overall weight of the product, the material of the above-mentioned support frame can be plastic. At this time, it can be produced by injection molding. It can be understood that during the production process research and design stage, because it is small batch production, the support frame can be obtained by three-dimensional printing. Under the condition that the process parameters are determined, the above-mentioned support frame can be produced by mold injection. In this way, the production cost can be reduced. In addition, the support frame and the shell can be fixed by adhesion. That is, the two upper frames and the shell upper cover 11 are adhesively fixed; the two lower frames and the shell lower cover 12 are adhesively fixed.

[0058] In addition, from Figure 5As can be seen, the metal cylindrical shell can also be provided with a cover plate G at the position corresponding to the window K. It can be coupled with the window K. The window K here can be subsequently provided with a display screen, thereby realizing functional display and key operation. The cover plate G can play a dustproof protection role. The material of the cover plate G here can also be plastic, such as engineering plastic PC (Polycarbonate, polycarbonate). In order to ensure the machining precision of the size of the cover plate G, numerical control machining production can be adopted.

[0059] At this time, the overall production process of the above product can be seen from Figure 6 . As shown in Figure 6 , for the upper shell cover, the upper shell cover and the first metal sheet can be first stamped and produced. Then the upper shell cover and the first metal sheet can be welded to complete the assembly of the upper shell cover. For the lower shell cover, the lower shell cover and the second metal sheet can be first stamped and produced. Then the lower shell cover and the second metal sheet can be welded to complete the assembly of the lower shell cover. Then, the upper shell cover and the lower shell cover are laser welded, and the weld is polished. After that, the support frame can be bonded inside the shell. That is, the upper frame is bonded on the inner side of the upper shell cover, and the lower frame is bonded on the inner side of the lower shell cover. Finally, the cover plate can be installed.

[0060] It should be noted that since the temperature during welding is usually high, and the support frame is of plastic material. Therefore, in order to avoid the support frame from being deformed by heat during the welding of the shell, the support frame generally needs to be bonded after the welding of the shell is completed. In addition, the production process of the upper shell cover and the lower shell cover can be carried out simultaneously or sequentially.

[0061] Some embodiments of the present disclosure also propose a product. The product can have a metal cylindrical shell. It can be obtained by using the production method described in any of the implementation manners of the above embodiments. In addition, the product can also include a control component installed inside the metal cylindrical shell.
