Description

Technical Field

[0001] This application relates to the technical field of bending and welding equipment, and more particularly to a bending and welding machine that performs bending and welding processes simultaneously. Background Technology

[0002] In the metal processing industry, bending and welding are core processes widely used in the manufacturing of engineering machinery, pressure vessels, and various metal structural components. In traditional production models, bending and welding processes are typically performed in separate stages: first, sheet metal or profiles are plastically deformed in terms of angle and shape using specialized bending equipment; then, the formed workpiece is transferred to a welding station for joint fixing or structural connection. While this segmented processing method is technologically mature, it reveals significant shortcomings in actual production environments.

[0003] Low efficiency in process flow has become a significant bottleneck; workpieces need to undergo multiple physical transfers between bending and welding stations, involving auxiliary operations such as hoisting, repositioning, and clamping. Each step consumes additional time and introduces the risk of human intervention. Especially in mass production scenarios, the cumulative effect of waiting time between stations leads to a significant extension of the overall production cycle, making it difficult to meet the demands of modern manufacturing for efficient and continuous production.

[0004] Meanwhile, the accumulation of positioning errors severely impacts product quality. Bent workpieces are susceptible to slight displacement during handling due to loose clamping, mechanical vibration, or operational deviations, requiring repeated calibration before welding. This not only increases the frequency and cost of manual adjustments but also easily leads to defects such as welding misalignment, discontinuous welds, or insufficient structural strength, ultimately compromising product consistency and reliability. These problems are particularly severe in high-precision manufacturing, highlighting the inherent limitations of traditional segmented processing methods.

Detailed Implementation

[0021] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the appended spirit and connotation.

[0022] The bending and welding machine that performs bending and welding processes simultaneously according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown in Figure 8, the bending and welding machine of this embodiment of the present application, which performs bending and welding processes simultaneously, includes a processing platform 10. A welding assembly 20 is provided on one side of the processing platform 10, a bending assembly 30 is provided on the processing table of the processing platform 10, a feeding assembly 40 is provided on the processing table of the processing platform 10 near the bending assembly 30, and a limiting assembly 50 is provided on the processing table of the processing platform 10. The welding assembly 20 includes a fixing plate 201 installed on one side of the processing platform 10. A gripping mechanism 202 is provided on the side of the fixing plate 201 near the processing platform 10, and a welding mechanism 203 is provided on the side of the fixing plate 201 near the gripping mechanism 202. A material blocking mechanism 204 is provided between the two sets of gripping mechanisms 202. The bending assembly 30 includes a support mechanism 301 disposed below the processing platform 10. A bending mechanism 302 and a pushing mechanism 303 are provided on the side of the support mechanism 301 near the processing platform 10.

[0024] The welding assembly 20 can be understood as a functional module for completing the welding operation of the workpiece, which can be implemented in various ways. For example, the welding assembly 20 can achieve precise positioning of the welding torch on the workpiece and welding operation through multi-degree-of-freedom motion. As a preferred embodiment, the welding assembly 20 can also achieve the movement of the welding head through a sliding rail structure, thereby adapting to welding needs at different positions. Furthermore, the gripping mechanism 202 can use pneumatic grippers or electromagnetic adsorption devices to grip and fix the workpiece, its main function being to reduce positional displacement during workpiece handling.

[0025] Specifically, the bending assembly 30 is designed to achieve workpiece forming operations, which can be achieved through hydraulic drive or servo motor drive. For example, the bending mechanism 302 can adopt a disc transmission structure, transmitting power to the bending component through the rotation of the disc, thereby achieving the angle forming of the workpiece. Furthermore, the pushing mechanism 303 can provide auxiliary thrust through spring loading or cylinder drive to ensure uniform force on the workpiece during the lifting process of the bending mechanism 302.

[0026] The main function of the limiting component 50 is to constrain the position of the workpiece, which can be achieved in various ways. For example, the limiting component 50 can adopt an adjustable stop structure, and the position of the stop can be manually adjusted to accommodate workpieces of different sizes. As a preferred embodiment, the limiting component 50 can also detect the workpiece position through a photoelectric sensor and achieve dynamic limiting in conjunction with an automatic adjustment mechanism.

[0027] The innovation of this application lies in integrating bending and welding functions onto the same processing platform 10, enabling simultaneous operation of the two processes. Compared to the traditional segmented processing mode, this design avoids the transfer of workpieces between the bending and welding processes, thereby reducing process connection time. Simultaneously, through the collaborative design of various functional components, the cumulative error caused by multiple positioning is effectively reduced, improving processing accuracy and efficiency. Thus, this application solves the problems of low process connection efficiency and accumulated positioning errors caused by segmenting the bending and welding processes.

[0028] The working principle of this application embodiment is as follows: The processing platform 10, as the basic structure of the overall equipment, provides a unified operating area for the simultaneous bending and welding processes. The welding assembly 20 is located on one side of the processing platform 10, with its fixing plate 201 mounted on the platform, providing a stable support point for the gripping mechanism 202 and the welding mechanism 203. The gripping mechanism 202 is positioned close to the processing platform 10, enabling it to quickly grip the workpiece and position it in the welding area, thereby reducing the workpiece transport distance and avoiding positioning errors caused by transport deviation. The welding mechanism 203 is located on the side of the fixing plate 201 close to the gripping mechanism 202. This adjacent arrangement allows for immediate welding after workpiece gripping, shortening the process interval and ensuring weld continuity. The material-blocking mechanism 204 is positioned between the two gripping mechanisms 202, dynamically blocking the workpiece during welding to prevent accidental movement, maintain the precise position of the welding point, and further reduce calibration requirements.

[0029] The bending assembly 30 is mounted on the processing table of the processing platform 10, with its support mechanism 301 located below the processing platform 10 to provide adaptive support for the workpiece. The bending mechanism 302 and the pushing mechanism 303 are arranged close to the processing platform 10, enabling them to apply thrust collaboratively during the bending process, ensuring the consistency of the bending angle and preventing subsequent welding misalignment due to bending deformation. The pushing mechanism 303 performs a pushing operation based on the elastic feedback of the support mechanism 301, ensuring uniform distribution of bending force, reducing stress concentration on the workpiece, and improving bending accuracy.

[0030] The feeding assembly 40 is located on the side of the processing table near the bending assembly 30, optimizing the initial positioning path of the workpiece and reducing manual intervention time. The limiting assembly 50 is located on one side of the processing table and can dynamically limit the workpiece according to its size, preventing the workpiece from shifting during feeding or processing, and further ensuring positioning accuracy.

[0031] Through the collaborative design of the aforementioned components, the bending and welding processes are seamlessly integrated in time and space on the same processing platform 10. The workpiece does not need to be transferred to the welding station after bending, avoiding the efficiency loss and positioning error accumulation caused by hoisting and reclamping operations in traditional segmented processing, thereby effectively improving the overall processing efficiency and product quality consistency.

[0032] This application further proposes that the gripping mechanism 202 includes a drive unit 2021 disposed on one side of the fixed plate 201, and the output end of the drive unit 2021 is connected to a hydraulic gripper 2022.

[0033] Specifically, the drive unit 2021 refers to the core component that provides power and motion control for the entire gripping action. It can be implemented using various drive forms such as servo motors, stepper motors, or pneumatic motors, with the aim of ensuring the accuracy and repeatability of the gripping path. The hydraulic gripper 2022 can be understood as an actuator that uses a hydraulic system to generate uniform and controllable gripping force. It can be implemented using single-acting or double-acting hydraulic cylinders in conjunction with gripping heads of different shapes, with the aim of adapting to the stable gripping requirements of workpieces of different materials or shapes.

[0034] In detail, this technical solution achieves precise gripping and positioning of workpieces through the organic combination of the drive unit 2021 and the hydraulic gripper 2022. The drive unit 2021, mounted on one side of the fixed plate 201, provides a stable support foundation and precise motion guidance for the entire gripping action, ensuring that each gripping action is executed accurately along a preset path. The hydraulic gripper 2022 adjusts its gripping force in real time by receiving the output signal from the drive unit 2021, and the constant gripping force it generates effectively suppresses the effects of external vibrations or disturbances during transport. A key feature of this design is that when a workpiece is gripped, the hydraulic gripper 2022 can instantly lock the workpiece position and maintain a stable gripping state throughout the transport process, significantly reducing waiting and calibration time during process transitions. Simultaneously, this solution, in conjunction with other functional modules such as the welding assembly 20 and the bending assembly 30, constitutes a complete bending and welding process, effectively improving overall processing accuracy and production efficiency.

[0035] This application further proposes a welding mechanism 203 including a second drive unit 2031, the output end of which is connected to a welding machine 2032, a connecting rod 2033 on one side of the welding machine 2032, and the other end of the connecting rod 2033 connected to an unloading component 2034.

[0036] Specifically, drive unit 2031 refers to a device capable of providing power output, which can be implemented using a servo motor, stepper motor, or hydraulic motor, etc., to provide precise and controllable power support for the movement of welding machine 2032. Welding machine 2032 can be understood as equipment with welding functions, which can be welding equipment such as resistance welding machine, laser welding machine, or ultrasonic welding machine, with the aim of achieving efficient welding of workpieces. In practical applications, connecting rod 2033 is specifically a rigid component used to transmit motion and force, such as a metal rod or composite material rod, with the purpose of transmitting the motion of welding machine 2032 to unloading component 2034. Furthermore, unloading component 2034 refers to a device capable of detaching the workpiece, which can take the form of a push plate, ejector pin, or pneumatic gripper, with the aim of achieving automatic unloading of the workpiece after welding.

[0037] In detail, this solution integrates the unloading function into the welding mechanism 203, achieving automatic workpiece detachment after welding. The connection between the drive unit 2031 and the welding machine 2032 ensures precise and controllable movement during the welding process, providing a stable foundation for subsequent unloading actions. One end of the connecting rod 2033 is connected to the welding machine 2032, and the other end is connected to the unloading component 2034. This structural design utilizes the positional change of the welding machine 2032 during welding to directly trigger the unloading mechanism, eliminating the need for additional sensors or control systems, simplifying the motion transmission path and reducing response delay. After welding is completed, the welding machine 2032 drives the unloading component 2034 via the connecting rod 2033, thereby achieving automatic workpiece removal. This design not only avoids positioning offset problems caused by manual intervention but also maintains the synchronous continuity of welding and bending processes.

[0038] The above technical solution effectively solves the problem that the workpiece is difficult to automatically detach from the welding position due to thermal effects or mechanical clamping after welding, reduces positioning errors and improves process connection efficiency.

[0039] This application further proposes that the unloading component 2034 includes a positioning block 20341 disposed at the other end of the connecting rod 2033, guide members 20342 are rotatably disposed on both sides of the positioning block 20341, a top block 20343 is disposed on the other side of the guide member 20342, and a protrusion 20344 for limiting the top block 20343 is disposed on one side of the fixing plate 201.

[0040] Specifically, the positioning block 20341 serves as the fixed base for the unloading component 2034. It can be made of rigid metal and aims to provide a stable support point for the entire unloading mechanism. The guide component 20342 can be understood as a connecting structure with a swing function. It can achieve rotation through hinges, bearings, or elastic connectors, dynamically adjusting the angle according to the actual position of the workpiece to avoid jamming caused by rigid contact. In practical applications, the top block 20343 is the component that directly contacts the workpiece. Its surface can be designed as arc-shaped or have a buffer layer to reduce damage to the workpiece surface and evenly distribute the ejection force. Furthermore, the protrusion 20344 is a structure used to limit the stroke range of the top block 20343. It can be adjusted by bolts or fixed with a stop block to prevent excessively forceful unloading actions from affecting workpiece stability.

[0041] In detail, the above solution uses positioning block 20341 to rigidly connect unloading component 2034 and connecting rod 2033, ensuring that the unloading action and the movement trajectory of welding mechanism 203 are synchronized. Furthermore, the rotational characteristics of guide component 20342 allow it to automatically adjust its angle according to the actual position of the workpiece, effectively avoiding friction or jamming that may occur during the ejection process in traditional rigid structures. The top block 20343, through the oscillating action of guide component 20342, contacts the workpiece surface with uniform pressure, reducing the impact of localized stress concentration on the workpiece. Simultaneously, the protrusion 20344 on the fixed plate 201 constrains the movement path of the top block 20343, ensuring consistency in each unloading action and fundamentally solving the problem of accumulated positioning errors caused by unstable unloading. Through this technical solution, not only is the stability and accuracy of the unloading process improved, but the connection efficiency between bending and welding processes is also significantly improved, meeting the high-efficiency processing requirements of mass production scenarios.

[0042] This application further proposes that the guide member 20342 includes a guide rod 203421 with one end connected to the positioning block 20341, the other side of the guide rod 203421 being rotatably connected to the top block 20343, a positioning shaft 203422 being provided between the two sets of guide rods 203421, and a spiral spring 203423 being sleeved on the positioning shaft 203422.

[0043] In practical applications, guide component 20342 refers to a structure used to guide the movement of top block 20343 and stabilize the workpiece position. It can be made of metal, such as stainless steel or aluminum alloy, to ensure sufficient strength and durability. Guide rod 203421 is a rotating connecting component; one end is fixedly connected to positioning block 20341, and the other end is rotatably connected to top block 20343, allowing top block 20343 to flexibly adjust its angle during unloading to adapt to workpieces of different shapes. Positioning shaft 203422, as the rotation center of top block 20343, primarily constrains the movement trajectory of top block 20343, preventing positioning errors caused by offset. Scroll spring 203423 is an elastic element that achieves the automatic reset function of top block 20343 by storing and releasing elastic potential energy. Springs with different stiffness coefficients can be used to adapt to different workpiece weights and unloading requirements, aiming to improve the stability and positioning accuracy of process synchronization.

[0044] Specifically, this technical solution effectively solves the problem of the top block 20343 failing to automatically reset after unloading by optimizing the structural design of the guide component 20342. One end of the guide component 20342 is rotatably connected to the top block 20343. This design allows the top block 20343 to flexibly adjust its angle as the workpiece moves during unloading, while ensuring the stability of its movement path. The positioning shaft 203422, serving as the rotation center of the top block 20343, not only constrains the movement trajectory of the top block 20343 but also provides a mounting base for the spiral spring 203423. When the top block 20343 rotates, the spiral spring 203423 is twisted and stores elastic potential energy. When the unloading action ends and the external force is removed, the spiral spring 203423 releases the stored energy. During the subsequent welding process, it drives the top block 20343 downwards. The protrusion 20344 limits the movement of the top block 20343, allowing it to precisely reset to its initial position. This elastic reset mechanism based on rotational motion characteristics requires no additional power source, eliminating the need for manual intervention and ensuring consistent positioning during continuous and synchronous bending and welding processes. Furthermore, the aforementioned structural design complements the overall layout of the welding assembly 20, further improving equipment operating efficiency and product consistency, ensuring that the top block 20343 pushes the processed part to complete unloading during its upward movement.

[0045] This application further proposes a material blocking mechanism 204 including a rotating shaft 2041 rotatably disposed on one side of a fixed plate 201, an outer ring 2042 sleeved on the rotating shaft 2041, and a material blocking part 2043 arranged in a ring array on the outer ring 2042.

[0046] In practical applications, the rotating shaft 2041 refers to a component capable of rotating around its own axis, which can be implemented using a bearing support structure or a bushing fit structure. The outer ring 2042 can be understood as a sufficiently rigid annular component whose inner diameter matches the outer diameter of the rotating shaft 2041. It can achieve synchronous rotation with the rotating shaft 2041 through a keyway connection or interference fit. Specifically, the material stop 2043 refers to a structure used to block and position materials. It can be implemented using a block or rod-shaped body made of wear-resistant material. Its purpose is to form a multi-point blocking function through a ring array distribution, providing connection support for the welding points of the bent and shaped workpiece.

[0047] In detail, this solution utilizes the rotational characteristics of the rotating shaft 2041 to enable the outer ring 2042 to drive the stop section 2043 to adjust its angle. This design effectively solves the problem that the fixed stop mechanism 204 cannot adapt to materials of different sizes. The outer ring 2042, acting as an intermediate carrier, ensures the smooth rotation of the stop section 2043 under the drive of the rotating shaft 2041. Multiple stop sections 2043 are evenly distributed on the circumference, forming switchable blocking points. When material positioning is required, the rotation angle of the rotating shaft 2041 is determined, resulting in unidirectional rotation. Furthermore, the rotation angle of the rotating shaft 2041 can be precisely set according to the material size and position information, allowing the appropriate stop section 2043 to automatically align with the working position. This design not only achieves dynamic adjustment but also ensures seamless switching of the stop function during continuous processing through a circular array layout, significantly improving process connection efficiency. Meanwhile, this mechanism, in conjunction with other components such as welding assembly 20 and bending assembly 30, can provide stable material positioning support when bending and welding are carried out simultaneously, thereby ensuring processing accuracy and product quality.

[0048] This application further proposes that the support mechanism 301 includes a support plate 3011 disposed below the processing platform 10, and a buffer 3012 is provided on the side of the support plate 3011 near the processing platform 10, and the output end of the buffer 3012 is connected to the movable plate 3013.

[0049] Specifically, the support plate 3011 refers to the component that provides a fixed mounting base for the entire support mechanism 301. It can be made of steel plate, cast iron plate, or other materials with sufficient rigidity, with the aim of ensuring the stability of the overall structure and preventing swaying caused by external forces. The buffer 3012 can be understood as an elastic element capable of absorbing dynamic impact forces. It can be implemented using springs, hydraulic dampers, or rubber pads, with the aim of reducing the transmission of vibrations generated during bending operations to the processing platform 10. In practical applications, the movable plate 3013 is specifically a component connected to the output end of the buffer 3012. It can be made of metal plate or composite material plate, with the aim of isolating vibrations through a flexible connection while allowing controlled minute displacements to maintain the precise positioning of the workpiece.

[0050] In detail, the support plate 3011, serving as the foundation for fixed installation, is positioned below the processing platform 10, providing a stable anchor point for the entire support mechanism 301. The buffer 3012, located adjacent to the processing platform 10, directly receives the dynamic impact force from the bending operation and absorbs energy through elastic deformation, effectively intercepting the impact source. The movable plate 3013, through the flexible connection with the buffer 3012, avoids workpiece displacement caused by rigid transmission, ensuring the stability of the workpiece position during synchronous welding. The unique feature of this design is that the combined effect of the buffer 3012's position and the movable plate 3013's flexible connection forms a system that can both absorb impact and maintain positioning accuracy, thus solving the problem of bending impact affecting the accuracy of synchronous welding.

[0051] Based on this, when the aforementioned support mechanism 301 is used in conjunction with other components such as the processing platform 10 and the bending assembly 30, the overall performance of the equipment can be further optimized. For example, the elastic characteristics of the buffer 3012 are matched with the dynamic operation of the bending mechanism 302 and the pushing mechanism 303 of the bending assembly 30, so that the impact force during the bending process is effectively absorbed. At the same time, the slight displacement of the movable plate 3013 can compensate for the lifting and lowering displacement adjustment of the workpiece, thereby ensuring the precise positioning of the bending area.

[0052] This application further proposes a bending mechanism 302 including a drive unit 3021 disposed on the side of the movable plate 3013 near the processing platform 10, the output end of the drive unit 3021 being connected to a rotating unit 3022, an inner groove 3024 being provided on one side of the rotating unit 3022, and a stop rod 3023 being provided on both sides of the inner groove 3024 on one side of the rotating unit 3022; and a pushing mechanism 303 including a drive component 3031 disposed on one side of the support plate 3011, the output end of the drive component 3031 being connected to a push block 3032, and the push block 3032 abutting against and connecting to the movable plate 3013.

[0053] Specifically, drive unit 3021 refers to a device capable of providing rotational power output, which can be implemented using a servo motor, stepper motor, or hydraulic motor, etc. Rotating unit 3022 refers to a component capable of controllable angle rotation under the drive of drive unit 3021. Inner groove 3024 is a recessed structure with a specific geometric shape, which can be designed as a V-groove, U-groove, or polygonal groove, etc., with the purpose of achieving preliminary workpiece positioning through shape matching. Support rod 3023 refers to a rigid component used to clamp and fix the workpiece; the support rod 3023 limits and bends the workpiece during rotation.

[0054] In practical applications, drive component 3031 refers to a power device capable of generating linear thrust, which can be implemented using hydraulic cylinders, pneumatic cylinders, or electric actuators. Push block 3032 is an intermediate component used to transmit thrust, and it can be designed in different structural forms such as flat plate, wedge, or curved surface, with the aim of optimizing the force transmission effect.

[0055] In detail, in the aforementioned bending and welding machine, the drive unit 3021 precisely controls the rotation angle of the rotating unit 3022, enabling the workpiece to complete the bending action along a predetermined trajectory. The inner groove 3024 on the rotating unit 3022 first embeds and positions the workpiece, limiting its lateral movement range. Simultaneously, the abutment rods 3023 on both sides apply symmetrical force to firmly fix the workpiece, ensuring no deviation occurs during bending. The thrust generated by the drive unit 3031 acts directly on the movable plate 3013 via the pusher block 3032. This direct abutment connection ensures uniform transmission of the thrust, allowing the movable plate 3013 to rise and fall smoothly, thus providing stable support for the bending process. This structural design effectively solves the problem of bending the workpiece during bending or unloading / loading.

[0056] Furthermore, the above scheme works organically with the support mechanism 301. The support plate 3011 provides basic support for the entire bending process, while the buffer 3012 absorbs excess stress through elastic deformation and can be raised and lowered to reset. Together with the pushing mechanism 303, it realizes the height adjustment of the bending mechanism 302 during the bending process.

[0057] This application further proposes that the feeding assembly 40 includes an outer baffle 401 disposed on one side of the processing surface of the processing platform 10, a feeding rack 402 disposed on the side of the outer baffle 401 near the processing platform 10, a limiting part 403 disposed on the inner side of the feeding rack 402, and a baffle block 404 disposed on the side of the outer baffle 401 away from the processing platform 10.

[0058] Specifically, the outer baffle 401 refers to the basic frame structure used to support and fix the entire feeding assembly 40. It can be made of welded metal profiles or formed into an integral frame through casting, aiming to provide a stable support foundation for the feeding process. The outer baffle 401 also has inclined end faces on its sides, allowing the workpiece to enter the clamping position through the inclined end faces, and cooperating with the hydraulic grippers 2022 to clamp the bent workpiece. The feeding rack 402 can be understood as a guide component that guides the workpiece smoothly into the processing area. It can achieve smooth workpiece transport through a combination of slide rails and rollers, aiming to reduce frictional resistance during workpiece movement. The limiting part 403 is a positioning component that provides lateral constraint to the workpiece. It can be implemented using elastic clamping arms or adjustable baffles, aiming to limit the lateral displacement of the workpiece. The stop block 404 can be a blocking stop component, which can be implemented using rubber pads in conjunction with a metal base or a hydraulic damper, aiming to prevent the workpiece from moving excessively due to inertia.

[0059] In detail, this solution uses the outer stop 401 as the overall support frame to ensure the stability of the feeding path and prevent workpiece movement trajectory deviation caused by equipment vibration. The positional relationship between the feed rack 402 and the outer stop 401 is carefully designed to guide the workpiece into the processing area via the shortest path, thereby reducing the possibility of mid-process shaking. The limiting part 403 is located inside the feed rack 402 and achieves precise positioning by conforming to the side of the workpiece. This internal limiting method is more effective than external limiting in eliminating minor deviations caused by gaps. The stop block 404 provides reverse resistance when the workpiece reaches the preset starting point through physical blocking, ensuring accurate workpiece stopping and ensuring alignment of the welded ends, providing a stable reference for subsequent bending and welding processes. The above components work together to solve the problem of lateral deviation or positional shaking of the workpiece during feeding, significantly improving positioning accuracy and production efficiency.

[0060] In the bending and welding machine that performs bending and welding processes simultaneously, the following technical solution is further proposed: the limiting component 50 includes a driving component 501 set on the processing surface of the processing platform 10, the output end of the driving component 501 is connected to a rotating rod 502, and the rotating rod 502 is provided with a positioning component 503 for limiting the processing workpiece on the side near the processing platform 10.

[0061] Specifically, drive component 501 refers to a power device capable of providing controllable motion output, which can be implemented using a cylinder, hydraulic cylinder, or servo motor, etc. Rotary rod 502 is a rigid transmission structure used to transmit the linear or rotational motion of drive component 501 to positioning component 503, which can be implemented through a linkage mechanism or a crank-slider mechanism. Positioning component 503 is a component that directly acts on the workpiece surface to achieve a limiting function; it can be designed as an adjustable clamping jaw or pressure plate to adapt to workpieces of different sizes and shapes and provide stable constraint force.

[0062] In detail, this technical solution solves the problem of unstable positioning of workpieces due to positional deviation during synchronous bending and welding through a dynamically adjustable limiting mechanism. Drive component 501, as an active control unit, initiates limiting actions in real time according to the processing progress, ensuring precise matching between the limiting operation and the bending and welding rhythm. Rotary rod 502, as a key transmission component, converts the output motion of drive component 501 into the controllable swing of positioning component 503. Positioning component 503 pushes the workpiece onto the outer stop 401, making the limiting process smooth and impact-free. Positioning component 503 dynamically adjusts its position as rotating rod 502 swings, adapting to different workpiece sizes and bending angles, and pushing the bent workpiece onto the outer stop 401. This design is particularly suitable for scenarios requiring rapid switching of limiting states in synchronous processes, such as allowing moderate workpiece deformation during bending and immediately applying stable constraints during welding, thereby eliminating the accumulation of positioning errors and ensuring welding accuracy and product consistency.

[0063] In summary, the bending and welding machine of this application embodiment, which performs bending and welding processes simultaneously, avoids the transfer process of the workpiece between the bending and welding processes, thereby reducing the process connection time. At the same time, through the coordinated design of various functional components, the cumulative error caused by multiple positioning is effectively reduced, improving processing accuracy and efficiency, while facilitating the switching between loading and unloading when welding is completed.

[0064] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
