Description

Technical Field

[0001] This invention relates to the technical field of bending centers, and in particular to a sheet metal bending processing system and method suitable for the production of stainless steel cabinets. Background Technology

[0002] Kitchen cabinets are essential pieces of furniture in the kitchen, serving as both storage for cookware and a work surface. Stainless steel cabinets, in particular, are increasingly becoming a common choice in modern kitchens due to their durability, environmental friendliness, and ease of cleaning. They are typically made from stainless steel sheets through processes such as cutting, bending, and assembly. In current production processes, sheets of different specifications are bent into shapes according to design drawings, and then the cabinets are assembled using welding or splicing methods.

[0003] However, existing sheet metal bending processes still have significant shortcomings. Specifically, due to the diverse specifications of cabinet products, the different sheet metal dimensions and bending methods, traditional bending equipment often relies on manual measurement of each sheet metal dimension when processing different specifications. The bending process involves manually adjusting the blades of the pressure mechanism according to bending requirements, and then completing the bending operation step by step using traditional methods. This processing method is cumbersome, highly dependent on manual experience, and results in relatively low overall bending efficiency.

[0004] More importantly, when faced with the production demands of small batches and multiple specifications of stainless steel cabinets, frequent equipment adjustments and tool adjustments significantly prolong production preparation time, making it difficult to achieve rapid response and efficient workflow. Therefore, existing bending processing methods are no longer suitable for the requirements of modern cabinet manufacturing for flexible and high-efficiency production, and there is an urgent need for a processing technology solution that can adapt to multiple specifications of sheet materials, reduce manual intervention, and improve bending efficiency. Summary of the Invention The purpose of this invention is to provide a sheet metal bending processing system and method suitable for the production of stainless steel cabinets, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: This invention provides a method for bending sheet metal suitable for stainless steel cabinet production. The bending device includes a pressing mechanism for pressing and fixing the sheet metal, a bending mechanism for bending the pressed sheet metal, and a conveying mechanism for feeding the sheet metal into or out of the pressing mechanism according to a preset posture. The pressing mechanism includes multiple pressing knives, which are configured to be selectively combined according to the bending requirements of the sheet metal. The sheet metal bending process includes the following steps: Prepare a sheet material to be processed. The sheet material is marked with marking information. The marking information is used to uniquely identify the specifications and dimensions of the sheet material and is associated with a preset bending control program. Identify and obtain the marking information for each of the aforementioned plates; Based on the identified marking information, the bending control program that matches the marking information is invoked; According to the invoked bending control program, the pressure knife mechanism, the bending mechanism and the conveying mechanism are controlled to coordinately execute the corresponding bending action process to complete the automated bending of the sheet metal.

[0006] As a further improvement to the above technical solution, the marking information is a QR code, barcode, or RFID tag.

[0007] As a further improvement to the above technical solution, the identification and acquisition of the marking information for each of the boards includes: The marking information is identified by an identification device, which is one of a scanner, a visual recognition module, or an RFID reader.

[0008] As a further improvement to the above technical solution, the bending control program includes at least the pressure knife stroke parameters, bending angle parameters, bending sequence parameters for each side of the sheet metal, blade configuration information, conveying step stroke parameters, and sheet metal posture parameters.

[0009] As a further improvement to the above technical solution, the step of controlling the pressing mechanism, the bending mechanism, and the conveying mechanism to coordinately execute the corresponding bending action process according to the invoked bending control program includes: Based on the blade configuration information, the combination of multiple pressing blades in the pressing mechanism is automatically adjusted, and the plate is pressed according to the pressing blade stroke parameters; According to the conveying step process parameters, the plate posture parameters, and the bending sequence parameters of each side of the plate, the different sides of the plate are sequentially sent to different preset positions of the pressing mechanism. Based on the bending angle parameters, the bending action is controlled to be performed on the compressed sheet material.

[0010] As a further improvement to the above technical solution, it also includes: A mapping relationship library between the marking information and the bending control program is established. The mapping relationship library is stored in the control device and is used to quickly retrieve the corresponding bending control program based on the identified marking information.

[0011] This invention also proposes a sheet metal bending system suitable for stainless steel cabinet production, comprising: A bending device includes a pressing mechanism for clamping and fixing a sheet metal, a bending mechanism for bending the clamped sheet metal, and a conveying mechanism for feeding the sheet metal into or out of the pressing mechanism according to a preset posture. The pressing mechanism includes multiple pressing blades, which are configured to selectively combine and assemble according to the bending requirements of the sheet metal. The bending device controls the pressing mechanism, the bending mechanism, and the conveying mechanism to collaboratively execute the corresponding bending action flow according to a invoked bending control program, so as to complete the automated bending of the sheet metal. The marking information carrier is set on the board to be processed to uniquely identify the specifications and dimensions of the board and is associated with the preset bending control program; An identification device is used to identify and acquire the marking information for each of the aforementioned plates; The control device is used to call a bending control program that matches the identified marking information based on the identified marking information; and to control the pressing mechanism, the bending mechanism and the conveying mechanism to work together to execute the corresponding bending action process according to the called bending control program, so as to complete the automated bending of the sheet metal.

[0012] As a further improvement to the above technical solution, the pressing mechanism further includes a fixed tool holder, a movable tool holder, a pressing drive structure, and a assembling drive structure. The pressing drive structure is used to drive the movable tool holder to move up and down above the fixed tool holder. Multiple pressing tools are arranged sequentially on the movable tool holder along the first transverse direction. The assembling drive structure is used to drive each pressing tool to move independently along the first transverse direction or to drive each pressing tool to rotate independently around an axis along the first transverse direction.

[0013] As a further improvement to the above technical solution, the bending mechanism is located on one side of the pressing mechanism along the second transverse direction, while the conveying mechanism is located on the other side of the pressing mechanism; the second transverse direction is perpendicular to the first transverse direction. The bending mechanism includes a bending blade and a bending drive structure. The bending blade extends along the first transverse direction, and the bending drive structure is used to drive the bending blade to move up and down or to drive the bending blade to rotate around an axis along the first transverse direction. The conveying mechanism includes a conveying platform, a suction cup, a rotary drive structure, and a conveying drive structure. The suction cup is disposed on the conveying platform. The rotary drive structure is used to drive the suction cup to rotate around its own vertical axis. The conveying drive structure is used to drive the suction cup to move along the second horizontal line.

[0014] As a further improvement to the above technical solution, the control device includes: A storage module for storing bending control programs associated with different marking information; The calling module is used to call the bending control program that matches the identified marking information based on the identified marking information; The execution module controls the pressing mechanism, the bending mechanism, and the conveying mechanism to work together to execute the corresponding bending action process according to the called bending control program.

[0015] Compared with the prior art, the sheet metal bending method and sheet metal bending system provided by the present invention have at least the following beneficial effects: This invention pre-sets unique markings on the sheet metal to identify its dimensions and associates these markings with a pre-defined bending control program. During processing, the markings are automatically identified and the matching bending control program is invoked, eliminating the need for manual measurement of sheet metal dimensions or manual parameter input. This achieves fully automated control from sheet metal identification to bending action execution, significantly reducing the degree of manual intervention and operational complexity. This invention utilizes a mechanism that links marking information with bending control programs. When changing to different specifications of sheet metal, the system can quickly and automatically switch to the corresponding bending control program without requiring manual re-measurement, re-assembly of the cutting tools, or resetting of equipment parameters. It is particularly suitable for the small-batch, multi-specification order requirements commonly found in stainless steel cabinet production, significantly shortening production preparation and changeover time and effectively improving overall processing efficiency. In this invention, the bending control program includes at least blade configuration information. The control system automatically adjusts the combination of multiple pressure blades in the pressure mechanism based on this information to adapt to the bending length and position requirements of the current sheet material. Compared to the existing technology that relies on manual experience to assemble the blades one by one, this invention not only improves blade assembly efficiency but also effectively avoids errors and inconsistencies caused by manual operation, thereby improving bending accuracy and product consistency. This invention uses a bending control program to coordinate the actions of the pressing mechanism, bending mechanism, and conveying mechanism. Following a preset conveying step, sheet metal posture, and bending sequence, different edges of the sheet metal are sequentially fed to the bending station for bending. The entire process is completed automatically by the control system without manual intervention, ensuring smooth transitions and consistent angles in multi-sided bending, thus improving the quality of the finished product.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0023] Kitchen cabinets are pieces of furniture used to store kitchen utensils and provide a work surface. Stainless steel cabinets are made from stainless steel sheet 200. Currently, the production process requires bending and assembling various sheet materials 200 according to design dimensions. However, due to the diverse specifications of kitchen cabinets and the varying sizes and bending methods of the sheet materials 200, traditional bending equipment requires individual measurement, separate cutting, and bending according to traditional techniques when processing different specifications of sheet materials 200. This method is inefficient and difficult to meet the production needs of small batches of multi-specification stainless steel cabinets. Therefore, this invention proposes a sheet material bending processing method suitable for stainless steel cabinet production.

[0024] The sheet metal bending method of the present invention is applied to the bending device 100, such as... Figure 1 , Figure 2 and Figure 3 As shown, the bending device 100 has a pressing mechanism 110 for pressing and fixing the sheet metal 200, a bending mechanism 120 for bending the pressed sheet metal 200, and a conveying mechanism 130 for feeding the sheet metal 200 into or out of the pressing mechanism 110 according to a preset posture. The pressing mechanism 110 includes a plurality of pressing blades 111, which are configured to be selectively combined according to the bending requirements of the sheet metal 200.

[0025] Regarding the specific structure of the pressure mechanism 110, such as Figure 4 and Figure 5As shown, the pressing mechanism 110 also includes a fixed blade holder 112, a movable blade holder 113, a pressing drive structure (not shown), and a blade-joining drive structure (not shown). The fixed blade holder 112 is mounted on the frame of the bending device 100 and serves as a lower support for pressing. The movable blade holder 113 is positioned above the fixed blade holder 112, with a vertical gap between them. The pressing drive structure drives the movable blade holder 113 to move up and down above the fixed blade holder 112. The pressing drive structure can be driven by a hydraulic cylinder, a pneumatic cylinder, or a lead screw motor. In this embodiment, a lead screw mechanism driven by a servo motor is preferred to precisely control the pressing stroke. When pressing the plate 200, the movable blade holder 113 is controlled to press down to a preset stroke position according to the thickness parameters of the plate 200, thereby achieving reliable pressing of the plate 200.

[0026] Multiple pressure knives 111 are arranged sequentially on the movable knife holder 113 along the first transverse direction (left-right direction in this embodiment). By moving the movable knife holder 113 up and down, all pressure knives 111 can be moved up and down synchronously to achieve overall pressing and releasing of the plate 200.

[0027] This embodiment provides two implementation schemes for knife-jointing methods, which can be selected or combined according to actual needs: Sliding knife-jointing method (not shown in the picture): Each pressing blade 111 is slidably mounted on the movable blade holder 113 in the left-right direction. Specifically, the lower surface of the movable blade holder 113 is provided with a slide rail extending in the left-right direction, and the upper end of each pressing blade 111 is provided with a slider that cooperates with the slide rail, so that the pressing blade 111 can slide independently along the slide rail.

[0028] The blade-jointing drive structure is used to drive each pressure blade 111 to move independently in the left-right direction. The blade-jointing drive structure includes a clamping component and a lateral movement drive module. The lateral movement drive module (e.g., a lead screw mechanism driven by a linear motor or servo motor) drives the clamping component to move in the left-right direction. When a pressure blade 111 needs to be moved, the lateral movement drive module moves the clamping component to the position of the target pressure blade 111, clamps and fixes the pressure blade 111, and then the lateral movement drive module moves the clamping component, thereby moving the pressure blade 111 to the target position. By moving each pressure blade 111 one by one, any combination of pressure blades 111 can be adjusted to adapt to the bending length requirements of different sheet metal 200.

[0029] Rotating knife-jointing method: like Figure 4 and Figure 5As shown, the upper end of each pressure blade 111 is hinged to the movable blade holder 113, allowing the pressure blade 111 to swing up and down around the hinge point. The blade drive structure is used to drive the pressure blade 111 to rotate, thereby causing the lower end of the pressure blade 111 to swing up and down. When the lower end of the pressure blade 111 swings upward to disengage from the working position, the pressure blade 111 does not participate in pressing the plate 200; when the lower end swings downward to the working position, the pressure blade 111 participates in pressing.

[0030] The blade-combining drive structure may include multiple rotary drive modules (such as miniature rotary electromagnets or miniature servo motors), each of which independently drives one pressure blade 111 to rotate. By controlling the operation of the rotary drive module of the corresponding pressure blade 111 according to the blade-combining configuration information, selective combination of blades can be achieved.

[0031] The advantages of the sliding blade assembly method are a large adjustment range and high flexibility for the pressure blade 111; the advantages of the rotating blade assembly method are a compact structure and fast response speed. Those skilled in the art can choose one or a combination of two methods according to actual production needs.

[0032] The bending mechanism 120 is located on one side of the pressing mechanism 110 along the second transverse direction. In this embodiment, the second transverse direction is the front-to-back direction. The bending mechanism 120 is set to be located on the rear side of the pressing mechanism 110, while the conveying mechanism 130 is set to be located on the front side of the pressing mechanism 110.

[0033] The bending mechanism 120 includes a bending blade 121 and a bending drive structure (not shown). The bending blade 121 extends in the left-right direction and its length matches the width of the pressure blade mechanism 110 to uniformly bend the entire edge of the sheet metal 200.

[0034] This embodiment provides two bending drive methods: Linear lifting bending method: like Figure 5 As shown, the bending drive structure is used to move the bending cutter 121 up and down. The bending drive structure can be a linear drive component, such as a hydraulic cylinder, a pneumatic cylinder, or a linear motor. When the bending cutter 121 moves upward, its upper end face abuts against the lower rear end surface of the sheet metal 200, causing the rear end of the sheet metal 200 to bend upward; when the bending cutter 121 moves downward, its lower end face abuts against the upper rear end surface of the sheet metal 200, causing the rear end of the sheet metal 200 to bend downward. By controlling the travel of the bending cutter 121, the bending angle can be precisely controlled.

[0035] Rotary bending method: The bending drive structure drives the bending cutter 121 to rotate around an axis extending in the left-right direction. The bending drive structure can be a rotary drive component, such as a rotary motor. During bending, the bending cutter 121 first moves to a position abutting against the rear end of the sheet metal 200. Then, the bending drive structure drives the bending cutter 121 to rotate around the axis, and the rear end of the sheet metal 200 rotates and bends along with the bending cutter 121, thus achieving the bending action. The rotary bending method has the advantages of uniform bending force and less risk of damaging the surface of the sheet metal 200.

[0036] like Figure 1 and Figure 3 As shown, the conveying mechanism 130 includes a conveying platform 131, a suction cup 132, a rotary drive structure (not shown) and a conveying drive structure (not shown).

[0037] The conveying platform 131 is used to support the sheet 200, and the suction cup 132 is disposed on the conveying platform 131 to adsorb and fix the bottom surface of the sheet 200. The suction cup 132 is preferably a vacuum suction cup 132, which generates negative pressure adsorption force through a vacuum generator, and can stably grasp the sheet 200 without leaving scratches on the surface of the sheet 200.

[0038] The rotary drive structure is used to drive the suction cup 132 to rotate around its own vertical axis. The rotary drive structure can use a rotary servo motor, which can precisely control the rotation angle. When it is necessary to bend different sides of the plate 200, the rotary drive structure drives the plate 200 to rotate, so that the side to be bent faces the bending mechanism 120.

[0039] The conveying drive structure is used to move the suction cup 132 in the back-and-forth direction. The conveying drive structure can be a lead screw mechanism driven by a linear motor or a servo motor. When the sheet metal 200 needs to be fed into the pressing mechanism 110, the conveying drive structure drives the suction cup 132 to move backward, sending the sheet metal 200 to the pressing station of the pressing mechanism 110; after bending is completed, the conveying drive structure drives the suction cup 132 to move forward, sending the sheet metal 200 out.

[0040] like Figure 6 As shown, the sheet metal bending process of the present invention includes the following steps: Step S100: Prepare the sheet material 200 to be processed. The sheet material 200 is marked with marking information. The marking information is used to uniquely identify the specifications and dimensions of the sheet material 200 and is associated with the preset bending control program. The specifications and dimensions of sheet material 200 include parameters such as length, width, thickness, material, number of bends, and bending angle.

[0041] In actual production, the marking information is preferably one of a QR code, barcode, or RFID electronic tag. Specifically, when the previous process of the sheet material 200 (such as blanking or stamping) is completed, the QR code label, barcode label, or RFID electronic tag is pre-attached to a predetermined position on the surface of the sheet material 200, or the marking information is directly sprayed or laser-engraved onto the surface of the sheet material 200. In this way, each sheet material 200 carries a unique identification, facilitating automated identification and processing in subsequent processes.

[0042] Step S200: Identify and obtain the marking information for each board 200.

[0043] In this embodiment, the identification device 300 identifies the marking information on each piece of board 200 to be processed in order to obtain the specification and size information of the board 200.

[0044] Specifically, the type of identification device 300 matches the type of marking information: when the marking information is a QR code or barcode, the identification device 300 uses a scanner or visual recognition module; when the marking information is an RFID electronic tag, the identification device 300 uses an RFID reader. In this embodiment, the identification device 300 is installed at the entrance of the conveying mechanism 130 or at a predetermined station of the bending device 100. When the sheet metal 200 arrives at the identification area, the identification device 300 automatically triggers the identification operation without manual intervention.

[0045] Step S300: Based on the identified marking information, call the bending control program that matches the marking information.

[0046] It should be noted that before step S100 (i.e., before formal production and processing), a mapping relationship database between the marking information and the bending control program needs to be established in advance. This mapping relationship database is stored in the storage module 410 of the control device 400, and exists in the form of a database table or configuration file. Each record contains at least the correspondence between the marking information and the bending control program. Through this mapping relationship database, the control device 400 can quickly and accurately retrieve the corresponding bending control program based on the identified marking information, realizing rapid production changeover between different specifications of sheet metal 200.

[0047] Step S400: According to the called bending control program, control the pressure knife mechanism 110, bending mechanism 120 and conveying mechanism 130 to coordinately execute the corresponding bending action process to complete the automated bending of the sheet 200.

[0048] The bending control program includes at least the following parameters: pressure cutter 111 stroke parameters, bending angle parameters, bending sequence parameters for each side of the sheet metal 200, cutter configuration information, conveying step stroke parameters, and sheet metal 200 posture parameters. These parameters collectively define the complete bending process for the current sheet metal 200.

[0049] like Figure 7 As shown, step S400 of the present invention includes the following sub-steps: Step S410: Based on the blade configuration information, automatically adjust the combination of multiple pressure blades 111 in the pressure blade mechanism 110, and press the plate 200 according to the stroke parameters of the pressure blades 111.

[0050] The tool configuration information includes: the number of the pressure tool 111 to be activated, the target position coordinates of each pressure tool 111, etc.

[0051] After the blade adjustment is completed, the pressing mechanism 110 is controlled to operate according to the stroke parameters of the pressing blade 111 to press and fix the sheet metal 200. Specifically, the pressing blade drive structure drives the movable blade holder 113 to move downward, so that the lower end face of the pressing blade 111 contacts the upper surface of the sheet metal 200 and applies a predetermined pressure. The pressure and the downward stroke are precisely controlled by the stroke parameters of the pressing blade 111 to ensure that the sheet metal 200 does not shift during the bending process.

[0052] Step S420: Based on the conveying step process parameters, the posture parameters of the plate 200, and the bending sequence parameters of each side of the plate 200, the different sides of the plate 200 are sequentially sent to the different preset positions of the pressing mechanism 110.

[0053] Specifically, the conveying mechanism 130 controls the forward and backward movement distance of the sheet metal 200 according to the conveying step stroke parameters, so that the side of the sheet metal 200 to be bent accurately enters the bending station of the pressing mechanism 110. Simultaneously, when it is necessary to switch to bending other sides of the sheet metal 200, the rotation drive structure of the conveying mechanism 130 drives the sheet metal 200 to rotate around the vertical axis by a predetermined angle (e.g., 90° or 180°) according to the attitude parameters of the sheet metal 200, so that the next side to be bent faces the bending mechanism 120. The above conveying and rotation actions are executed sequentially according to the bending sequence parameters of each side of the sheet metal 200 until all sides to be bent have been processed.

[0054] Step S430: Based on the bending angle parameters, control the bending action to bend the pressed sheet 200.

[0055] Specifically, the bending drive structure moves or rotates the bending blade 121, causing it to abut against the edge of the sheet 200 to be bent, and continues to apply force to bend that edge of the sheet 200 to a preset angle. During the bending process, the control device 400 monitors the bending angle in real time (e.g., through feedback from an angle sensor or encoder). When the target angle is reached, the bending drive structure stops and resets, completing one bending operation.

[0056] like Figure 1 As shown, this invention also proposes a sheet metal bending system suitable for stainless steel cabinet production, comprising: a marking information carrier 210, an identification device 300, a control device 400, and the aforementioned bending device 100. The specific structure of the bending device 100 has been described in detail in the preceding sections and will not be repeated here. The components are described in detail below.

[0057] like Figure 3 As shown, the marking information carrier 210 is set on the plate 200 to be processed, and is used to uniquely identify the specifications and dimensions of the plate 200 (such as the length, width, thickness, material, number of bending edges and bending angle of the plate 200), and is associated with the preset bending control program.

[0058] In practical applications, the information carrier 210 can be one of a QR code label, a barcode label, or an RFID electronic tag.

[0059] The identification device 300 is used to identify and acquire the marking information on each piece of material 200 to be processed. The type of the identification device 300 matches the type of the marking information carrier 210. When the information carrier 210 is a QR code or barcode, the identification device 300 uses a scanner or a visual recognition module; When the information carrier 210 is an RFID electronic tag, the identification device 300 uses an RFID card reader.

[0060] The identification device 300 is installed at the entrance of the conveying mechanism 130 or at a predetermined identification station of the bending device 100. When the board 200 arrives at the identification area, the identification device 300 automatically triggers the identification operation without manual intervention.

[0061] The control device 400 is electrically connected to the identification device 300, the pressure knife mechanism 110, the bending mechanism 120, and the conveying mechanism 130, respectively. The control device 400 is used to call the bending control program that matches the marking information identified by the identification device 300, and control the pressure knife mechanism 110, the bending mechanism 120, and the conveying mechanism 130 to coordinately execute the corresponding bending action process according to the called bending control program, so as to complete the automated bending of the sheet metal 200.

[0062] like Figure 8 As shown, the control device 400 in this embodiment includes: a storage module 410, a calling module 420, and an execution module 430.

[0063] Storage module 410 is used to store bending control programs associated with different marking information. Storage module 410 may be a non-volatile memory in which a mapping relationship library between marking information and bending control programs is pre-established.

[0064] The calling module 420 is used to invoke the bending control program that matches the identified marking information. The calling module 420 can be implemented using a database query engine to quickly retrieve the corresponding program path based on the marking information ID.

[0065] The execution module 430 is used to control the pressing mechanism 110, bending mechanism 120 and conveying mechanism 130 to work together to execute the corresponding bending action process according to the bending control program called.

[0066] Compared with the prior art, the sheet metal bending method and system provided by the present invention have at least the following beneficial effects: I. Achieving automated and intelligent bending processing This invention pre-sets unique markings on the sheet metal 200 to identify its dimensions and associates these markings with a pre-defined bending control program. During processing, the system automatically identifies the markings and calls the matching bending control program, eliminating the need for manual measurement of the sheet metal 200 dimensions or manual parameter input. This achieves fully automated control from sheet metal 200 identification to bending action execution, significantly reducing the degree of manual intervention and operational complexity.

[0067] II. Significantly improve processing efficiency in small-batch, multi-specification production scenarios. This invention utilizes a "marking information - bending control program" association mechanism. When changing to different specifications of sheet metal 200, the system can quickly and automatically switch to the corresponding bending control program without requiring manual re-measurement, re-cutting, or resetting of equipment parameters. This technology is particularly suitable for the small-batch, multi-specification order requirements commonly encountered in stainless steel cabinet production, significantly shortening production preparation and changeover times, and effectively improving overall processing efficiency.

[0068] 3. To achieve automatic combination and assembly of the pressing mechanism 110, thereby improving accuracy and consistency. The bending control program of this invention includes at least blade configuration information. Based on this information, the control system automatically adjusts the combination of multiple pressure blades 111 in the pressure blade mechanism 110 to adapt to the bending length and position requirements of the current sheet material 200. Compared to the prior art's method of manually assembling blades one by one based on experience, this invention not only improves blade assembly efficiency but also effectively avoids errors and inconsistencies caused by manual operation, significantly improving bending accuracy and product consistency.

[0069] IV. Achieving coordinated control of sequential bending of more than 200 sides of sheet metal This invention uses a bending control program to coordinate the actions of the pressing mechanism 110, bending mechanism 120, and conveying mechanism 130. Following a preset conveying step, the posture of the sheet metal 200, and the bending sequence, different edges of the sheet metal 200 are sequentially fed to the bending station for sequential bending. The entire process is completed automatically by the control system without manual intervention, ensuring smooth transitions and consistent angles in multi-sided bending, effectively improving the quality of the finished product.

[0070] V. Possesses good industrial applicability and scalability The technical solution of this invention does not depend on a specific specification or shape of the sheet material 200. It only requires setting readable marking information on the sheet material 200 and pre-storing the corresponding bending control program to adapt to the processing needs of sheet materials 200 of different sizes and bending requirements. Furthermore, the marking information can use various carriers such as QR codes, barcodes, or RFID electronic tags, and the identification device 300 can be configured accordingly, exhibiting good industrial applicability and scalability.
