Description

Technical Field

[0001] This invention relates to fire door welding technology, and more specifically to a welding device for steel fire doors. Background Technology

[0002] Steel fire doors are essential safety devices specifically designed to prevent the spread of flames and smoke during a fire. They are typically made of high-quality steel, possessing excellent fire resistance and maintaining structural integrity and insulation for a certain period, thus buying valuable time for evacuation and fire rescue. During the manufacturing process, steel fire doors require welding to firmly connect different metal components together to form a unified structure. Good welding techniques help improve the door's sealing performance, reducing the penetration of heat, smoke, and toxic gases, thereby providing more time for evacuation.

[0003] Chinese invention patent CN118002989B discloses a welding fume treatment device for steel fire door bodies. This device uses symmetrically arranged filter units on both sides of the welding torch head. When the welding torch head generates a large amount of fumes during welding, the filter units can quickly absorb the fumes, providing good and rapid absorption and preventing fumes from overflowing. The fumes filtered by the filter units are then purified by a purification unit before being discharged, preventing the inhalation of welding fumes by personnel and ensuring safety. Simultaneously, when the welding fumes enter the negative pressure chamber, the filter screen filters out large particles of impurities. These large particles accumulate on the outer surface of the filter screen. An electric push rod operates periodically, causing the filter screen to reciprocate, allowing the outer surface of the filter screen to rub against a baffle rod. The baffle rod scrapes and removes material from the outer surface of the filter screen, preventing impurities from accumulating and affecting the filtration efficiency of the filter screen.

[0004] When using existing equipment, uneven or rough welding platforms may prevent the various components of fire doors from being accurately aligned, resulting in differences at the workpiece joints. This leads to errors in the welding process. In addition, welding slag and spatter are often generated during the welding process. These residues not only affect the appearance of the welded joint but may also affect its performance. Furthermore, the metal surface is exposed to high-temperature environments, making it prone to oxidation and affecting the long-term durability of the components. Summary of the Invention

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Example: Please refer to Figures 1-9 A welding device for a steel fire door includes a base 1, a movable column 11 slidably mounted on the end of the base 1, and a cleaning component 3 slidably mounted on the end of the movable column 11, which performs preliminary cleaning of the welding position of the fire door.

[0041] In this scheme, the end of the base 1 is equipped with a telescopic device such as an electric telescopic rod, which drives the moving column 11 to move until it reaches the appropriate position and then stops.

[0042] At the same time, the cleaning component 3 is moved by the moving column 11, and the cleaning component 3 performs preliminary cleaning of the welding position to ensure that the welding part remains flat during welding.

[0043] Furthermore, the adjustment component 2, which is assembled at the end of the base 1, protects the fire door during docking and processing. The adjustment component 2 includes a base 21 fixedly connected to the base 1, with positioning blocks 22 symmetrically fixedly installed at the end of the base 21, and a driving component 23 fixedly installed between the two positioning blocks 22.

[0044] In this embodiment, the driving component 23 is a device with power output, such as a motor, and is connected to an external control device. When the driving component 23 is started, it synchronously drives the driving rod 231, which is fixedly installed at its output end, to rotate.

[0045] Furthermore, a first swing block 24 is rotatably mounted on one side of the end of the positioning block 22, while a second swing block 25 is rotatably mounted on the end of the positioning block 22 that is away from the first swing block 24.

[0046] Specifically, the first swing block 24 and the second swing block 25 are in a parallel state and are limited by the positioning block 22, thereby ensuring that the first swing block 24 and the second swing block 25 remain stable as a whole when subjected to force.

[0047] Furthermore, an elastic element 26 is rotatably mounted on the end of the second swing block 25, and the end of the elastic element 26 is rotatably connected to the end of the base 21.

[0048] Specifically, the elastic element 26 is a component with a buffering function composed of springs, dampers and other structures. The elastic element 26 buffers the force on the second swing block 25, ensuring that the protective door remains stable as a whole during welding.

[0049] Furthermore, a drive rod 231 is fixedly installed at the output end of the drive member 23, an adjustment block 27 is rotatably installed at the end of the drive rod 231, a rotating block 272 is rotatably installed at the end of the adjustment block 27, the end of the rotating block 272 is fixedly connected to the end of the drive rod 231, a support plate 273 is fixedly installed at the end of the rotating block 272, and a limiting rod 274 is rotatably installed on one side of the adjustment block 27.

[0050] Specifically, when the driving component 23 drives the driving rod 231 to rotate, it synchronously drives the rotating block 272, which is fixedly installed at the end of the driving rod 231, to rotate. Since the end of the rotating block 272 is fixedly installed with a support plate 273, the angle of the support plate 273 can be adjusted to make it suitable for different scenarios.

[0051] The middle part of the support plate 273 is a telescopic rod, which can extend and retract freely when the support plate 273 moves, so as to meet the needs of different scenarios and reduce interference during operation.

[0052] The end of the drive rod 231 is provided with a telescopic rod, and the end of the telescopic rod is longitudinally rotatably connected to the end of the rotating block 272. The drive rod 231 can drive the rotating block 272 to rotate, and at the same time, when the entire adjusting block 27 moves downward, the connecting end of the rotating block 272 can be protected by the telescopic rod.

[0053] The limiting rod 274 is used to limit the two adjusting blocks 27 to prevent the adjusting blocks 27 from deviating from the set trajectory. The limiting rod 274 is a telescopic rod.

[0054] Furthermore, the ends of the adjusting block 27 are symmetrically provided with docking holes 271, and the inner walls of the two docking holes 271 are rotatably connected to the ends of the first swing block 24 and the second swing block 25, respectively.

[0055] Specifically, the first swing block 24 and the second swing block 25 are rotatably connected through the docking hole 271 provided on the adjusting block 27, so that when the rotating block 272 moves downward under force, it can be buffered by the second swing block 25 and the elastic element 26.

[0056] Furthermore, a fixing block 28 is fixedly installed at the end of the base 21, and a support plate 281 is fixedly installed at the end of the fixing block 28.

[0057] Specifically, the lower end of the fixed block 28 is equipped with a telescopic device such as an electric telescopic rod. The electric telescopic rod drives the fixed block 28 to move up and down, thereby driving the support plate 281 fixedly installed at its end to move until it is in contact with the outer surface of the protective door and then stops.

[0058] Furthermore, a movable rod 29 is slidably mounted on one side of the fixed block 28, a movable block 291 is fixedly mounted on the end of the movable rod 29, and a locking block 292 is fixedly mounted on the end of the movable block 291.

[0059] Specifically, the movable rod 29 moves to move the movable block 291 fixedly installed at its end, and simultaneously moves the locking block 292 fixedly installed on the movable block 291, thereby engaging the outer surface of the fire door and locking the fire door after it has been fully adjusted.

[0060] By adjusting component 2, the workpiece can be precisely positioned to ensure accurate alignment during welding, avoiding weak or uneven welding caused by positional deviations. At the same time, the fine adjustment of component 2 allows for easy adaptation of workpieces of different sizes and shapes, improving the versatility of the equipment.

[0061] Furthermore, locking block 292 provides initial constraints on the fire door, facilitating subsequent docking.

[0062] Furthermore, the cleaning component 3 includes a fixed plate 31 that is slidably connected to the movable column 11. The fixed plate 31 has a groove 311 at its end. A movable block 34 is slidably installed on the inner wall of the groove 311. A gear rod 341 is fixedly installed at the end of the movable block 34.

[0063] In this embodiment, when the moving block 34 is subjected to force, it drives the gear rod 341 fixedly installed at its end to move. The moving block 34 is limited by the slide groove 311, thereby limiting the movement trajectory of the moving block 34.

[0064] Furthermore, a turntable 32 is rotatably mounted on the end of the fixed plate 31, and a protrusion 321 is fixedly mounted on the end of the turntable 32 near its edge. Meanwhile, a drive plate 33 is slidably mounted on the outer surface of the protrusion 321. One side of the drive plate 33 is rotatably connected to the end of the fixed plate 31, and the end of the drive plate 33 meshes with the outer surface of the gear rod 341.

[0065] Specifically, when the gear rod 341 moves, it drives the drive plate 33 that meshes with it to move. Since one side of the drive plate 33 is rotatably connected to the end of the fixed plate 31, the drive plate 33 rotates around the connection with the fixed plate 31.

[0066] The drive plate 33 has a groove at its end, and the inner wall of the groove is slidably connected to the outer surface of the protrusion 321, so that when the drive plate 33 rotates, it works with the protrusion 321 to drive the turntable 32 to rotate.

[0067] The end of the turntable 32 extends through and to the outside of the fixed plate 31. A cleaning plate 322 is fixedly installed at the end of the turntable 32. The cleaning plate 322 is driven to rotate by the turntable 32, so as to clean the welding position when the welding is completed, and to remove the impurities remaining after welding.

[0068] Furthermore, a guide groove 312 is provided at the end of the fixed plate 31, and a leveling scraper 343 is slidably installed on the inner wall of the guide groove 312. The end of the leveling scraper 343 is engaged with the outer surface of the gear rod 341.

[0069] Specifically, the leveling scraper 343 is confined by the guide groove 312, so that the leveling scraper 343 moves along the inner wall of the guide groove 312, thereby protecting the leveling scraper 343.

[0070] Meanwhile, the flatness after welding can be detected by adjusting the leveling scraper 343.

[0071] Furthermore, a limiting plate 35 is fixedly installed on one side of the fixing plate 31. The limiting plate 35 has a concave cross-section, and a rotating shaft 351 is rotatably installed on the inner wall of the limiting plate 35.

[0072] Specifically, the end of the limiting plate 35 is provided with a device with power output such as a motor and is connected to an external control device. At the same time, the output end of the motor is fixedly connected to the end of the rotating shaft 351, so that when the motor starts, it synchronously drives the rotating shaft 351 fixedly installed at its output end to rotate.

[0073] Furthermore, a power plate 36 is fixedly mounted on the outer surface of the rotating shaft 351, and a power rod 39 is rotatably mounted on the end of the power plate 36.

[0074] Specifically, when the rotating shaft 351 rotates, it synchronously drives the power plate 36 to rotate. The outer surface of the rotating shaft 351 is provided with a movable groove, and the inner wall of the movable groove is fitted with the inner wall of the power plate 36, so that the power plate 36 can slide on the rotating shaft 351 and rotate synchronously with the rotating shaft 351.

[0075] Simultaneously, as the power plate 36 moves, it works in conjunction with the power rod 39 to drive the ring 37 to rotate around the end of the connecting block 38 until it conforms to the current scenario.

[0076] The end of the limiting plate 35 is fixedly equipped with a telescopic device such as an electric telescopic rod, which is used to drive the power plate 36 to move.

[0077] Furthermore, a connecting block 38 is fixedly installed on the outer surface of the rotating shaft 351, and a ring 37 is rotatably installed on the outer surface of the connecting block 38. An annular groove 371 is formed on the outer surface of the ring 37.

[0078] Specifically, when the rotating shaft 351 rotates, it synchronously drives the connecting block 38, which is fixedly installed on its outer surface, to rotate. Since the end of the connecting block 38 is provided with a ring 37, the ring 37 rotates synchronously with the connecting block 38.

[0079] Furthermore, a docking block 342 is fixedly installed at the end of the movable block 34, and the outer surface of the docking block 342 fits into the inner wall of the annular groove 371.

[0080] Specifically, when the ring 37 rotates, it works in conjunction with the annular groove 371 to drive the docking block 342 to push, thereby driving the moving block 34 to reciprocate.

[0081] The cleaning component 3 can be used to clean the fire door after welding, and quickly remove welding slag, oxides and other impurities from the welding area. During the cleaning process, potential welding defects such as porosity and cracks can be detected in time and repaired immediately, avoiding the accumulation of welding quality problems in subsequent work.

[0082] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0083] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
