Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device for processing metal products. Background Technology

[0002] Metal rings are commonly used connecting components in the industrial field. Their production process usually includes three core steps: material cutting, cold bending, and welding sealing. First, metal plates or bars are cut into straight strips of a fixed length according to the circumference of the ring. Then, the straight strips are cold bent into C-shaped open rings with openings at both ends by a rolling machine. Finally, the two ends of the opening are fused together by laser welding, resistance welding, or other methods to form a closed-loop structure. However, during the cold bending process, the two ends of the opening are prone to axial and radial misalignment due to factors such as plate springback, tooling positioning errors, and material thickness tolerances, making it impossible to achieve seamless fitting in the same plane.

[0003] Currently, existing welding devices generally have the following defects when welding open rings: conventional welding devices can only achieve single-position clamping, making it difficult to simultaneously correct and center misaligned open ends. During the welding process, misaligned open ends will form stepped lap welds, resulting in a significant reduction in the effective stress-bearing cross section of the weld. In subsequent use, the steps of the misaligned welds are prone to stress concentration points, which are very likely to crack from the root of the weld under alternating loads or impact loads, greatly reducing the overall strength and service life of the metal ring and affecting the welding quality and safety of the product.

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1-9 This is the first embodiment of the present invention, which provides a welding device for metal product processing, including: a base 1, on one side of which a Z-axis driver 11 is fixedly connected; a Y-axis driver 12 is fixedly connected to one side of the Z-axis driver 11; a welding device 13 is fixedly connected to one side of the Y-axis driver 12; a PLC controller 14 is fixedly connected to one side of the top of the base 1; a servo slide rail 2 is fixedly connected to the other side of the top of the base 1; a slide table 21 is disposed on both sides of the top of the servo slide rail 2; a positioning member 23 is disposed on the top of the slide table 21; and a seat cylinder 24 is fixedly connected to the corresponding position of the slide table 21. On one side, a stop plate 25 is fixedly connected to the top of the seat 24. A through groove 26 is opened on the corresponding side of the seat 24. A calibration plate 27 is slidably connected to the inner cavity of the through groove 26. A calibration component 28 is set on one side of the calibration plate 27 for calibrating and aligning the open ring. A centering plate 3 is set on the corresponding side of the calibration plate 27. Grinding belts 31 are fixedly connected to both sides of the plate. A housing 32 covers the surface of the grinding belts 31 and is fixedly connected to the centering plate 3. A swing component 33 is set on one side of the housing 32. An air blower or an external air pipe is set at the bottom of the housing 32 to blow away impurities generated during polishing from the weld.

[0033] The base 1 serves as the overall load-bearing body, which fixes the various functional components and ensures the overall stability of the equipment operation. The welding equipment 13 is adjusted in two axes by the Z-axis driver 11 and the Y-axis driver 12, which can adapt to the welding point requirements of different specifications of open rings. It is equipped with a PLC controller 14 to realize the automated control of the equipment.

[0034] The base 1 is equipped with a servo slide rail 2 and a slide table 21 on top, which can realize the synchronous opposite displacement of the two sets of welding positioning mechanisms, providing power support for the docking and calibration of the open ring; the positioning component 23 set on the top of the slide table 21 can realize the clamping and fixing of the open ring before welding, and prevent the workpiece from shifting and shaking during the welding process; the seat 24, the abutment plate 25 and the sliding calibration plate 27 cooperate with each other to correct and align the misaligned end of the open ring after cold bending, solving the defect that traditional equipment cannot synchronously calibrate the misalignment of the workpiece.

[0035] The centering plate 3 can center the open ring and ensure the neatness of the workpiece placement; the grinding belts 31 on both sides can polish the welding end face of the open ring to remove burrs, oxide scale and impurities. The housing 32 protects the grinding belts 31. At the same time, the air fan or external air pipe equipped at the bottom of the housing 32 can blow away polishing dust and impurities in real time, completely avoiding the problem of false welding and false welding caused by impurity residue; the swinging component 33 can drive the grinding mechanism to swing and avoid interference with the workpiece docking and welding operation, effectively adapting to the automated continuous welding process.

[0036] Z-axis driver 11, Y-axis driver 12, welding equipment 13, PLC controller 14, servo slide rail 2 and slide table 21 are all existing technologies, which are clearly known to those skilled in the art, and will not be described in detail here.

[0037] Example 2, refer to Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the positioning component 23 includes a cylinder 231 fixedly connected to the top of the slide table 21. The telescopic rod of the cylinder 231 is fixedly connected to a positioning plate 232. A positioning pressure block 233 is fixedly connected to the bottom of the positioning plate 232. Rollers are provided on the contact surfaces of the seat cylinder 24 and the positioning pressure block 233 with the open ring to reduce the friction force when the calibration plate 27 calibrates the open ring.

[0039] The positioning component 23 consists of a cylinder 231, a positioning plate 232, and a positioning block 233. The cylinder 231 serves as a power source, driving the positioning plate 232 and the bottom positioning block 233 to move vertically downwards, pressing the open ring placed on the surface of the seat cylinder 24. This prevents the workpiece from shifting or loosening during welding and calibration, ensuring the stability of the welding operation. Simultaneously, a roller structure is added to the contact surface between the seat cylinder 24, the positioning block 233, and the open ring to specifically address the problem of excessive friction on the contact surface during workpiece calibration and alignment. During the process of the calibration plate 27 pushing the end of the open ring to align and correct misalignment, the rollers can significantly reduce the sliding friction resistance between the workpiece and the positioning and bearing structures. This not only prevents the workpiece surface from being squeezed, scratched, or deformed, but also makes the misalignment calibration operation of the open ring smoother, preventing incomplete calibration and secondary misalignment caused by friction jamming.

[0040] Specifically, the calibration component 28 includes a fixed base 281 fixedly connected to the top of the base 1. Movable rods 282 are hinged to the bottom of both sides of the fixed base 281. Each side of the movable rods 282 passes through the seat cylinder 24 and is hinged to a movable plate 283. A cylinder 284 is fixedly connected to the bottom of the movable plate 283. The telescopic rod of the cylinder 284 is fixedly connected to the calibration plate 27.

[0041] The calibration component 28 uses the fixed base 281 as a fixed base and relies on the two sets of movable rods 282 hinged to the fixed base 281 to form a stable hinged transmission structure, which can move synchronously with the displacement of the seat cylinder 24; the movable plate 283 drives the cylinder 284 to move, thereby making the calibration plate 27 slide stably in the cavity of the through groove 26; during the calibration operation, it can push the misaligned ends of the open ring to fit against the abutment plate 25, forcibly correcting the end misalignment and offset problems caused by cold bending, and greatly improving the welding quality and structural strength of the metal ring.

[0042] Specifically, a pressure sensor 285 is fixedly connected to the surface of the calibration plate 27 and works in conjunction with the PLC controller 14.

[0043] The pressure sensor 285 is fixedly installed on the surface of the calibration plate 27 and can detect the contact pressure between the calibration plate 27 and the end of the open ring in real time. It can adaptively adjust the calibration stroke and clamping force according to the open ring of different widths. This can avoid incomplete calibration and end misalignment caused by insufficient pressure, and prevent the workpiece from being deformed by excessive pressure. It is suitable for calibration and welding operations of metal open rings of various specifications, greatly improving the versatility of the equipment.

[0044] Specifically, sliders 286 are fixedly connected to both sides of the top of the movable plate 283, and slide rods 287 are slidably connected to the inner cavity of sliders 286. Both sides of slide rods 287 are fixedly connected to the inner wall of the seat cylinder 24.

[0045] By setting sliders 286 on both sides of the top of the movable plate 283, and matching them with the slide rod 287 fixed to the inner wall of the seat 24, a symmetrical sliding guide structure is formed. During the hinge transmission process of the movable rod 282, the movable plate 283 can slide smoothly in a straight line along the slide rod 287, effectively limiting the offset of the movable plate 283 and eliminating the shaking, jamming, and offset phenomena that occur during the transmission process.

[0046] Specifically, movable rods 288 are hinged to the top of both sides of the fixed base 281. Movable plates 289 are hinged to the corresponding side of the movable rods 288 through the base 24. A drive rod 2810 is fixedly connected to the corresponding side of the movable plate 289. A drive rail 2811 is slidably connected to the surface of the drive rod 2810. A connecting shaft 2812 is fixedly connected to the corresponding side of the drive rail 2811. A connecting groove 2813 is opened on the surface of the base 24. A flattening block 2814 is fixedly connected to the corresponding side of the connecting shaft 2812 through the connecting groove 2813.

[0047] The movable plate 289 is hinged to the movable rod 288, causing the movable plate 289 to drive the drive rod 2810 to slide inside the drive rail 2811, achieving adaptive displacement adjustment. Then, the connecting shaft 2812 connected to the drive rail 2811 passes through the connecting groove 2813 of the seat cylinder 24, driving the flattening block 2814 at the end to move up and down synchronously. During the process of the seat cylinder 24 driving the open ring to butt weld, the flattening block 2814 can fit against the welding end face of the open ring, forming a bidirectional pressing support structure with the positioning block 233 at the top. This flattens and corrects the welding end face with slight misalignment, provides close-range support, completely eliminates the step overlap phenomenon of the welding end face, ensures that the welding end face is flat and fits, and thus ensures that the weld is fully formed and the stress section is complete. This reduces the risk of stress concentration in the weld from the root and greatly improves the structural strength and service life of the metal ring after welding.

[0048] Specifically, the bottom of the movable plate 289 is fixedly connected to the slider 2815, the inner cavity of the slider 2815 is slidably connected to the slide rod 2816, and both sides of the slide rod 2816 are fixedly connected to the inner wall of the seat cylinder 24.

[0049] During the process of the hinged transmission of the movable rod 288 and the displacement of the movable plate 289, the slider 2815 can slide smoothly and linearly along the sliding rod 2816, effectively constraining the displacement trajectory of the movable plate 289 and preventing problems such as deviation, tilting, and jamming during the transmission process.

[0050] Specifically, a slider 2817 is fixedly connected to the other side of the drive rail 2811, and a slide rod 2818 is slidably connected to the inner cavity of the slider 2817. The top of the slide rod 2818 is fixedly connected to the inner wall of the seat 24.

[0051] When the drive rod 2810 slides relative to the drive rail 2811 and drives the flattening block 2814 to rise and fall, the slider 2817 slides smoothly along the slider 2818, which can effectively offset the lateral stress generated by the displacement of the drive end and prevent the drive rail 2811 from deflecting or shaking.

[0052] During use, the worker places the cold-bent C-shaped open ring onto the surface of the base 24 and between the abutment plate 25 and the calibration plate 27, so that the openings on both sides of the open ring are in contact with the centering plate 3, achieving initial centering of the workpiece and ensuring that the workpiece is placed neatly. Then, the cylinder 231 of the positioning component 23 is activated. The telescopic rod of the cylinder 231 drives the positioning plate 232 and the bottom positioning pressure block 233 to move down, pressing and fixing the open ring. After the workpiece is fixed, the grinding belts 31 on both sides of the centering plate 3 are activated to polish the welded end face of the open ring, removing burrs, oxide scale and impurities from the end face. At the same time, the air fan or external air pipe at the bottom of the housing 32 blows away the dust and debris generated during grinding in real time, preventing the problem of false welding or cold welding caused by the residue of impurities.

[0053] After the grinding operation is completed, the servo slide rail 2 on the top of the base 1 drives the two side slides 21 to slide in opposite directions, causing the two sets of seat cylinders 24 to move closer synchronously, so that the welding end faces on both sides of the open ring gradually fit together; during the displacement of the seat cylinder 24, the swinging component 33 moves in sync, and the sleeve rod 335 fixed by the seat cylinder 24 cooperates with the guide groove 337 of the sleeve 334 through the surface guide block 336, so that the sleeve 334 slides and rotates along the sleeve rod 335, causing the swinging rod 331, the housing 32 and the grinding belt 31 to swing and shift as a whole. By moving away from the welding area of ​​the open ring, structural interference is completely avoided, ensuring unobstructed workpiece docking. At the same time, the calibration component 28 starts working simultaneously. The movable rod 282, which is hinged at the bottom of the fixed seat 281, moves in conjunction with the displacement of the seat cylinder 24, pushing the movable plate 283 to slide smoothly along the sliding rod 287 via the slider 286. This causes the cylinder 284 and the calibration plate 27 to slide along the through groove 26 of the seat cylinder 24, pushing the misaligned ends of the open ring to fit against the abutment plate 25, forcibly correcting the axial and radial misalignment caused by cold bending.

[0054] During the calibration process, the pressure sensor 285 on the surface of the calibration plate 27 detects the workpiece contact pressure in real time. When the pressure reaches the preset threshold, it sends a signal to the PLC controller 14, which locks the stroke of the cylinder 284 to adapt to the calibration requirements of different width open rings and ensures complete alignment of the ends. At the same time, the movable rod 288 hinged to the fixed base 281 moves synchronously, driving the movable plate 289 to slide along the slide rod 2816 via the slider 2815. The drive rod 2810 slides relative to the drive rail 2811. With the guide limit of the slider 3 2817 and the slide rod 3 2818, the connecting shaft 2812 and the flattening block 2814 rise smoothly, forming a bidirectional support and pressing with the top positioning block 233 to flatten and correct the welding end face of the open ring, eliminating the stepped structure formed by misalignment and overlap. Finally, the welding position of the welding equipment 13 is adjusted by the Z-axis driver 11 and the Y-axis driver 12, and laser welding is performed on the flat, aligned, and impurity-free welding end face to complete the closed-loop processing of the open ring.

[0055] Example 3, referring to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the swinging component 33 includes a swing rod 331 fixedly connected to one side of the housing 32. The swing rod 331 is provided with a rotating seat 332. The bottom of the rotating seat 332 is fixedly connected to a load-bearing plate 333 and fixedly connected to the fixed seat 281.

[0057] The swinging component 33 uses the swinging rod 331 fixed on one side of the housing 32 as the swinging body, and works with the rotating seat 332 to realize the rotation swinging function. The rotating seat 332 is fixedly connected to the fixed seat 281 of the calibration component 28 through the bottom load plate 333, ensuring the installation stability and load-bearing capacity of the overall structure. During the process of the seat 24 driving the open ring to align and weld, the swinging component 33 can drive the housing 32 and the internal grinding belt 31 to swing and shift as a whole, so that the grinding mechanism is away from the welding area of ​​the open ring, avoiding the situation where the grinding structure blocks the welding point and interferes with the workpiece mating.

[0058] Specifically, sleeves 334 are rotatably connected to both sides of the rotating seat 332 and are fixedly connected to the swing rod 331. A sleeve rod 335 is slidably connected to the inner cavity of the sleeve 334 and is fixedly connected to the seat 24. A guide block 336 is fixedly connected to the surface of the sleeve rod 335, and a guide groove 337 is opened on the surface of the sleeve 334.

[0059] When the seat 24 moves in opposite directions with the slide table 21, the sleeve rod 335 will slide inside the sleeve 334. Thus, through the cooperation of the guide block 336 and the guide groove 337, the sleeve 334 can drive the swing rod 331 to swing, so that the housing 32 and the internal grinding belt 31 are away from the welding area of ​​the open ring.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
