Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment, specifically a device for preventing the welding of boiler combustion cloth from sticking together. Background Technology
[0002] In modern industrial manufacturing, the combustion cloth of a boiler premixed burner head is typically made of woven nickel mesh, which needs to be welded to an arc-shaped stainless steel perforated plate. This welding process requires the two materials to be instantly melted together by a high current to achieve a strong bond. However, traditional welding methods, namely manual resistance welding equipment, present significant problems and challenges.
[0003] First, manual operation introduces high-risk safety hazards. Operators must hold the workpiece by hand for welding; as the welding head wears down, the resistance increases, and the welding head may stick to the nickel mesh, causing the operator to lose control of the workpiece and potentially leading to an accident. Furthermore, prolonged hand-held operation increases the operator's physical exertion, easily leading to fatigue and further exacerbating the safety risks.1
[0004] Secondly, inconsistent welding quality is also a major problem. Relying on manual experience and foot switches to control the welding process makes it difficult to ensure consistent quality at each weld point. Human error frequently leads to weak welds or over-welding. Furthermore, manual operation makes it difficult to guarantee uniform weld spacing, directly impacting the performance and appearance of the final product.
[0005] Finally, the low production efficiency of traditional welding methods is also a significant issue. Each weld requires manual adjustment of position and activation of a foot pedal, making the entire process time-consuming and unsuitable for large-scale production. Furthermore, manual operation limits the automation level of the production line, hindering the improvement of overall production efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-3This utility model relates to a welding anti-adhesion device for boiler combustion cloth, comprising a cylinder 1, a frame 6, a rod frame 11, a guide rod 2, a welding head 5, a welding frame 7, and a fixture frame 8. The cylinder 1 is fixedly installed on the top of the frame 6, and the output end of the cylinder 1 passes through the frame 6. The fixture frame 8 is fixedly installed on the output end of the cylinder 1. The front end of the fixture frame 8 is provided with a clamping column 10, the welding head 5 passes through the clamping column 10, and the bottom end of the welding head 5 passes through the fixture frame 8. The welding head 5 is fixedly installed on the clamping column 10 and the fixture frame 8. The rod frame 11 is located on both sides of the frame 6. The guide rod 2 passes through the rod frame 11, and the lower end of the guide rod 2 is connected to the welding frame 7. An induction switch 4 is fixedly installed on the rod frame 11. An isolation ring 3 is fitted on the top end of the guide rod 2. The isolation ring 3 is adapted to the induction switch 4. A spring 9 is fitted on the guide rod 2, and the spring 9 is located between the rod frame 11 and the welding frame 7.
[0028] This anti-adhesion device for welding boiler combustion cloth aims to prevent the welding head 5 from sticking to the workpiece during the welding process by combining mechanical structure and induction control system, thus ensuring welding quality and production efficiency. The device consists of cylinder 1, frame 6, rod frame 11, guide rod 2, welding head 5, welding frame 7, and fixture frame 8. All components work together to achieve an automated welding process and respond promptly when abnormalities are detected.
[0029] Working principles of various preferred technical solutions
[0030] Pneumatic drive and stationary
[0031] Cylinder 1: Mounted on top of frame 6, it provides power to move the entire welding mechanism up and down. The output end of cylinder 1 passes through frame 6 and connects to fixture frame 8, ensuring that welding head 5 can accurately reach the predetermined position.
[0032] Fixture frame 8: Fixed at the output end of cylinder 1, with a clamping column 10 at the front end for supporting and fixing welding head 5 to ensure its stability during the welding process.
[0033] Design of guide rod 2 and welding frame 7
[0034] Guide rod 2: Passes through rod frame 11 and connects to welding frame 7, serving as a guide while transmitting power from cylinder 1. Welding frame 7 adopts a V-shaped structure design, which helps to better adapt to workpiece surfaces of different shapes and improve welding quality.
[0035] Spring 9: Mounted on guide rod 2, located between rod frame 11 and welding frame 7. When all mechanisms are raised after welding is completed, the elasticity of spring 9 helps to separate the slightly adhered weld head 5 and workpiece, ensuring smooth welding the next time.
[0036] Sensing control and safety mechanisms
[0037] Inductive switch 4 and isolation ring 3: An inductive switch 4 is fixedly installed on the rod 11, and an isolation ring 3 is fitted onto the top of the guide rod 2. The two are used in conjunction. Under normal circumstances, the isolation ring 3 is below the inductive switch 4, and the signal is maintained. When welding is completed and the lifting mechanism is activated, if the welding head 5 is not stuck to the workpiece, the isolation ring 3 descends with the guide rod 2, and the signal from the inductive switch 4 disappears. Conversely, if sticking occurs, the isolation ring 3 cannot descend normally, the inductive switch 4 continues to sense the signal, and the equipment will stop and issue an audible and visual alarm.
[0038] Adjustment bracket 14: The inductive switch 4 is fixed to the rod frame 11 by an L-shaped adjustment bracket 14. The adjustment bracket 14 is provided with an adjustment port 13 to facilitate the adjustment of the position of the inductive switch 4. Two limit nuts 12 are symmetrically fitted on the inductive switch 4, which clamp the adjustment bracket 14 through a threaded structure to ensure the stability and accuracy of the inductive switch 4.
[0039] Orientation and Stability
[0040] Guide sleeve 16: It is set at the end of the rod frame 11, through which the guide rod 2 passes, ensuring that the guide rod 2 always maintains a straight line during the up and down movement, avoiding deviation or jamming, and improving the stability and reliability of the entire system.
[0041] Installation and Integration
[0042] Mounting bracket 15: Mounting bracket 15 is provided on both the frame 6 and the pole frame 11. The mounting bracket 15 has several mounting holes, which makes it easy to fix the entire device to the production line or other work platform, and also facilitates subsequent maintenance and replacement of parts.
[0043] The welding frame 7, clamping column 10, and welding head 5 in this utility model can be installed by welding or flange connection.
[0044] The inductive switch 4 in this utility model adopts a mature sensing device, such as a cylindrical inductive switch 4 with the following model numbers: BNI6-M18MN3U-G7 / 2 (Turck), NBNM-E18-A24V-Z19C (Pepperl+Fuchs), and E2A-M18KS-N1 (Omron).
[0045] Detailed Workflow
[0046] Preparation stage
[0047] Install the anti-adhesion device onto the designated work platform, connect the air source, power supply and control system, and ensure that all components are in good condition.
[0048] Adjust the position of the induction switch 4 according to the specific welding task to match the isolation ring 3, and at the same time calibrate other relevant parameters (such as welding current, time, etc.).
[0049] clamping workpiece
[0050] Place the boiler combustion cloth to be welded in the appropriate position and use auxiliary clamps to fix the workpiece to ensure that it will not shift during the welding process.
[0051] Welding Start
[0052] The operator starts the equipment, and cylinder 1 moves the entire welding mechanism downward until welding head 5 contacts the workpiece surface. At this point, welding head 5 begins the welding operation, melting the material to form a weld.
[0053] Monitoring and Feedback
[0054] During the welding process, the inductive switch 4 monitors the position of the isolation ring 3 in real time. If the welding head 5 is in normal contact with the workpiece and there is no adhesion, when all mechanisms are raised after welding is completed, the isolation ring 3 descends with the guide rod 2, and the signal from the inductive switch 4 disappears.
[0055] If adhesion occurs, the isolation ring 3 will not be able to descend normally, the induction switch 4 will continue to sense the signal, the equipment will immediately stop and issue an audible and visual alarm to remind the operator to handle the abnormal situation.
[0056] Separation and Reset
[0057] Under normal circumstances, after welding is completed, all mechanisms are raised, the elastic force of spring 9 helps to separate welding head 5 and workpiece, guide rod 2 and isolation ring 3 begin to move down, and induction switch 4 senses the signal again, ready to weld the next point.
[0058] If there is only slight adhesion, the spring force of spring 9 is sufficient to bounce the adhesion away, ensuring that the next welding can proceed smoothly.
[0059] Loop operation
[0060] The equipment repeats the above steps according to the preset program, completing the operation of multiple welding points in sequence. After a certain number of welds are completed, the system will issue a warning to prompt the operator to check or replace welding head 5, ensuring long-term stable operation.
[0061] Maintenance
[0062] Regularly check the condition of each component, such as cleaning guide rod 2 and replacing worn seals, to ensure that the device is always in optimal working condition.
[0063] Technological advantages
[0064] High precision: The relative position between the welding head 5 and the workpiece is monitored in real time by the induction control system, ensuring that each welding is accurate and improving the consistency of welding quality.
[0065] Safety: When abnormal adhesion occurs, the equipment can respond quickly and take protective measures to avoid potential safety hazards and ensure the personal safety of operators.
[0066] Easy to maintain: The modular design makes it easy to disassemble and replace the components, simplifying daily maintenance and reducing repair costs.
[0067] Reliability: The use of high-quality materials and precision machining processes enhances the overall durability and reliability of the device, extending its service life.
[0068] In summary, the boiler combustion cloth welding anti-adhesion device provided by this utility model combines multiple advanced technologies and user-friendly designs, significantly improving the safety and efficiency of the welding process. It is suitable for the large-scale industrial production needs of various boiler combustion cloths. It not only solves many problems existing in the prior art, but also provides manufacturers with a high-precision, high-reliability solution, ensuring the consistency and reliability of product quality.
