Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and more particularly to a welding device for processing steel structure profiles and a welding method thereof. Background Art

[0002] Steel structural profiles are materials with various cross-sectional shapes made from steel through processes such as hot rolling, cold bending, or welding. These primarily include I-beams, H-beams, channels, angles, steel pipes, and steel plates. These profiles offer high strength, excellent plasticity and toughness, and superior workability, making them widely used in construction, bridge construction, and machinery manufacturing. They are not only able to withstand heavy loads, but also offer advantages such as low weight, rapid construction, and excellent seismic resistance, making them an indispensable material in modern engineering structures.

[0003] At present, in the production and processing flow of circular stainless steel pipe profiles, after the stainless steel pipe is bent and formed, it is necessary to use a special welding device to weld the resulting butt joint gap, so that the steel pipe can achieve a closed shape. However, there are significant problems in the actual application of the existing traditional stainless steel pipe butt joint welding device. It requires that the butt joint must be precisely aligned with the welding mechanism, and there are two main existing alignment methods: one is manual alignment, which is very prone to errors due to human factors, affecting welding accuracy and quality; the other is to use an advanced visual automatic alignment system. Although this system can achieve high-precision alignment effects, its cost of use remains high and its subsequent maintenance is also quite complicated. For the semi-automatic welding devices currently widely available on the market, it is extremely difficult to upgrade and difficult to be widely promoted and applied in the industry. This has largely restricted the efficient development and quality improvement of stainless steel pipe welding technology. Summary of the Invention

[0037] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0038] Example 1

[0039] Please refer to Figures 1 to 3, a welding device for processing steel structure profiles, comprising: a welding mechanism 1, a feeding mechanism 2 and a discharging mechanism 3. Among them, the welding mechanism 1 is installed at the end of the feeding mechanism 2. Since the welding mechanism 1 belongs to the prior art, it will not be described in detail here. The discharging mechanism 3 is located at the discharging end of the welding mechanism 1. The feeding mechanism 2 includes a main frame 21, a rolling support assembly 22 and a pushing assembly 23. The rolling support assembly 22 and the pushing assembly 23 are both installed on the main frame 21. The rolling support assembly 22 is used to provide rolling support for the workpiece. The rolling support assembly 22 includes an alignment indicator for indicating whether the workpiece joint is in a standard position. The pushing assembly 23 includes a belt conveyor 231, a posture adjustment member 232 and a resistance member 233. The posture adjustment member 232 includes a connector, a positioning member and a corrective member with automatic movable reset capability. The connector is fixedly mounted on the belt conveyor 231. The corrective member is slidably mounted on the upper end of the connector. The corrective member is used to cooperate and engage with the end of the welding gap on the workpiece. After the end of the corrective member is squeezed by the workpiece, it can slide laterally on the connector, and after the squeezing force on the corrective member disappears, it can automatically move and reset. The positioning member is provided on the connector. The positioning body is used to position the corrective member reset to a preset position and automatically release the positioning after the workpiece moves to the preset position. The resistance member 233 is mounted on one end of the belt conveyor 231 away from the connector. The resistance member 233 is used to provide resistance to the end of the workpiece in the forward direction.

[0040] It should be noted that when the above-mentioned welding device is in use, the stainless steel tube 4 is manually placed on the rolling support assembly 22, and the rolling support assembly 22 provides support for the bottom of the stainless steel tube 4, and pushes the stainless steel tube 4 to move linearly along the rolling support so that its end gradually approaches the welding mechanism 1. When the end of the stainless steel tube 4 contacts the resistance member 233, the pushing of the stainless steel tube 4 is stopped, and then the stainless steel tube 4 is manually rotated according to the indication mark of the alignment indicator so that the butt joint on it can be aligned with the alignment indicator. Since the alignment indicator is aligned with the welding mechanism 1, the butt joint on the adjusted stainless steel tube 4 can be preliminarily aligned with the welding mechanism 1, and then the posture adjustment member 23 is driven by the operation of the belt conveyor 231. 2 moves close to the end of the stainless steel pipe 4. When the end of the correcting body contacts the end of the stainless steel pipe 4, the stainless steel pipe 4 is blocked by the resistance member 233 at this time and will not be pushed by the correcting body. The correcting body is subjected to the reverse force of the stainless steel pipe 4, causing it to slide and shrink toward the side of the connecting body and move horizontally synchronously. If the correcting body contacts the stainless steel pipe 4, it will be engaged with the butt joint. At this time, during the horizontal movement of the correcting body, the stainless steel pipe 4 can be driven to rotate synchronously. If the correcting body does not engage with the butt joint of the stainless steel pipe 4 at the beginning, the correcting body will automatically engage with the butt joint after the correcting body moves horizontally and aligns with the butt joint, and then drive the stainless steel pipe 4 to rotate. When the correcting body slides to the preset maximum displacement, it stops moving horizontally. Under the driving action of the belt conveyor 231, the entire posture adjustment part 232 continues to apply a thrust to the stainless steel pipe 4. When the thrust is greater than the resistance of the resistance part 233, the stainless steel pipe 4 can be separated from the resistance of the resistance part 233 and continue to approach the side of the welding mechanism 1. At this time, the correction body begins to automatically move and reset with the help of its own reset ability, and simultaneously drives the stainless steel pipe 4 to rotate in the opposite direction. When the correction body moves to the preset standard position, it is restricted by the positioning body and cannot continue to move and reset. Since the standard position is set according to the standard position required by the welding mechanism 1, the stainless steel pipe 4 stays in the position at this time, and the butt joint on it can be precisely aligned with the welding mechanism 1. In this way, high-precision posture adjustment of the stainless steel pipe 4 is achieved. After the welding process is completed, the welding pipe 4 is put into the welding mechanism 1, and the welding process is completed. The welding process is completed, and the welding process is completed. The welding process is completed, and the welding process is completed. The welding process is completed, and the welding process is completed. The welding process is completed, and the welding process is completed. The welding process is completed, and the welding process is completed. The welding process is completed, and the welding process is completed.The positioning body automatically releases its positioning effect on the correction body, and the correction body continues to move and resets to its initial state. The entire posture adjustment member 232 also returns to its initial position under the driving action of the belt conveyor, and then a new stainless steel pipe 4 is placed. In this way, the continuous welding operation of the stainless steel pipe 4 can be achieved. This welding device uses a push component 23 to achieve precise adjustment of the posture of the stainless steel pipe 4. Compared with traditional manual adjustment, its accuracy is higher. Compared with the current advanced visual automatic alignment system, the device has a lower operating cost and can be directly applied to existing semi-automatic welding equipment without large-scale upgrading and modification, which is easy to be widely promoted and used in the industry.

[0041] For more details, please refer to Figures 4 to 6 The connecting body is a rectangular plate 2321, and the correcting body is an insert block structure. The insert block structure includes a plug block 2322, a roller 2323, a support spring 2324, a matching slider 2325, a slide groove 2326 and a guide bevel 2327. The slide groove 2326 is set at the upper end of the connecting body, one end of the plug block 2322 cooperates with the slide groove 2326 to slide, and the guide bevel 2327 is set on the inner bottom wall of the slide groove 2326. The matching slider 2325 is fixedly installed at the bottom of the slider, and the matching slider 2325 cooperates with the guide bevel 2327 to slide, and the roller 2323 is rotatably installed at the end of the plug block 2322 away from the slide groove 2326.

[0042] It should be noted that when the above-mentioned plug-in block structure is in use, the entire plug-in block structure moves toward one end of the stainless steel tube 4 together with the connector. When the end of the plug-in block 2322 contacts the stainless steel tube 4, it is squeezed by the stainless steel tube 4, causing it to begin to shrink into the connector. Under the sliding action of the matching slider 2325 and the guide bevel 2327, the plug-in block 2322 moves laterally synchronously in the slide groove 2326 during the shrinkage process, and the support spring 2324 is compressed synchronously. During the lateral movement of the plug-in block 2322, the roller 2323 rolls in contact with the stainless steel tube 4, which can reduce the contact between the plug-in block 2322 and the stainless steel tube 4. The friction between the stainless steel tube 4 and the plug-in block 2322 is such that if the end of the plug-in block 2322 is in contact with the stainless steel tube 4 and the end of the plug-in block 2322 is just in contact with the butt joint on the stainless steel tube 4, the stainless steel tube 4 can be driven to move laterally during the transverse movement of the plug-in block 2322. If the plug-in block 2322 is not in contact with the stainless steel tube 4, the elastic force of the support spring 2324 can also make the plug-in block 2322 automatically engage with the butt joint during the transverse movement of the plug-in block 2322. In this way, the plug-in block 2322 can be ensured to engage with the butt joint, thereby making the plug-in block 2322 able to drive the stainless steel tube 4 to rotate. When the support spring 2324 is compressed to its maximum After the contraction, the plug-in block 2322 stops moving. Then, as the correcting body continues to move with the belt conveyor 231, the plug-in block 2322 no longer moves, and the extrusion force it exerts on the stainless steel pipe 4 gradually increases and eventually exceeds the resistance of the resistance member 233, thereby causing the stainless steel pipe 4 to break away from the resistance of the resistance member 233 and continue to approach the side of the welding mechanism 1. At this time, since the elastic force of the support spring 2324 is greater than the friction force on the stainless steel pipe 4, during the movement of the stainless steel pipe 4, due to the loss of the reaction force of the stainless steel pipe 4, the elastic force of the support spring 2324 can drive the plug-in block 2322 to gradually move. It is reset by horizontal movement and extended forward synchronously. Since the plug-in block 2322 is still engaged with the butt joint at this time, the stainless steel pipe 4 starts to rotate under the driving action of the plug-in block 2322. When the plug-in block 2322 reaches the preset position for activity reset, the positioning body is engaged with the bottom of the plug-in block 2322, so that the plug-in block 2322 stops the activity reset. At this time, since the position of the positioning body is set according to the welding mechanism 1, after the plug-in block 2322 is engaged, the butt joint and the welding mechanism 1 are precisely aligned, thereby realizing the secondary precise alignment operation of the stainless steel pipe 4 to ensure that the subsequent welding mechanism 1 can perform precise welding.

[0043] Please refer to Figure 6 and Figure 7The positioning body is an electromagnetic card block structure, which includes a positioning card block 2328, a return spring 2329, an electromagnet 23210 and a displacement sensor 23211. The positioning card block 2328 is slidably installed in the connector, and the top of the positioning card block 2328 extends upward into the guide inclined groove 2327. The side of the positioning card block 2328 facing the matching slider 2325 is set as an inclined surface. The return spring 2329 is sleeved on the lower end of the positioning card block 2328, and the two ends of the return spring 2329 are respectively in contact with the positioning card block 2328 and the inside of the connector. The electromagnet 23210 is located directly below the positioning card block 2328. The electromagnet 23210 is fixed to the inside of the connector, and the displacement sensor 23211 is installed on one side of the connector.

[0044] The retraction of the positioning block 2328 prevents the plug block 2322 from moving upwards and returning to the original position. The arrangement is such that the butt joint can be precisely aligned with the welding mechanism 1. After the end of the stainless steel tube 4 is separated from the plug-in block 2322, the displacement sensor 23211 detects that the plug-in block 2322 has reached the preset displacement and starts to send a signal to the control unit. After receiving the signal, the control unit controls the electromagnet 23210 to be energized. (It should be noted that the control logic between the displacement sensor 23211, the electromagnet 23210 and the external control unit belongs to the prior art and will not be described in detail here.) After the electromagnet 23210 is energized, it generates an attraction to the positioning block 2328, causing the positioning block 2328 to begin to shrink downward, and eventually causing the positioning block 2328 to separate from the plug-in block 2322. The plug-in block 2322 is no longer blocked by the positioning block 2328 and continues to move and reset under the elastic force of the support spring 2324. In this way, the plug-in block 2322 successfully completes the reset action.

[0045] Please refer to Figure 4 and Figure 8The resistance member 233 includes a baffle 2331, a torsion spring 2332 and a contact roller 2333. The bottom end of the baffle 2331 is hinged to one side of the belt conveyor 231. The torsion spring 2332 is installed at the hinged end of the baffle 2331. The contact roller 2333 is rotatably installed on the top of the baffle 2331. The force of the torsion spring 2332 must be greater than the elastic force of the support spring 2324.

[0046] When the locking cam 2331 is in the unlocked position, the locking cam 2331 is unlocked, and the locking cam 2332 is unlocked, so that the locking cam 2331 is unlocked.

[0047] Please refer to Figure 9 The belt conveyor 231 includes a driving motor 2311, a conveyor belt 2312 and two transmission rollers 2313. The two transmission rollers 2313 are respectively rotatably installed at the two ends of the main frame 21, and the two transmission rollers 2313 are connected through the conveyor belt 2312. The driving motor 2311 is installed on the main frame 21, and the driving end of the driving motor 2311 is fixed to the rotating end of one of the transmission rollers 2313.

[0048] It should be noted that when the above-mentioned belt conveyor 231 is in use, the driving motor 2311 rotates, which can drive the transmission roller 2313 connected thereto to rotate. Under the transmission action of the conveyor belt 2312, the two transmission rollers 2313 can rotate synchronously, and the connector moves in a straight line along with the conveyor belt 2312. The circulating activity of the conveyor belt 2312 can drive the circulating activity of the connector to realize the continuous circulating action of the pushing component 23, and can perform continuous pushing operations on the stainless steel pipe 4.

[0049] Please refer to Figure 10 The alignment indicator is a laser emitter 222 , which is mounted on one side of the top limiter near the end of the main frame 21 , and the laser emitter 222 irradiates a vertical laser beam downward.

[0050] Please refer to Figure 10The rolling support assembly 22 includes a plurality of bottom support rollers 221 and a plurality of top stoppers, which are linearly and evenly distributed along the top of the main frame 21. The top stoppers include a support seat 223, a lifting seat 224, an adjustment rod 225, and two tapered rollers 226. The bottom of the support seat 223 is fixed to the top of the main frame 21, the lifting seat 224 is slidably mounted on the inner side of the support seat 223, the adjustment rod 225 is threadedly mounted on the top of the support seat 223, and the bottom end of the adjustment rod 225 is rotatably connected to the top of the lifting seat 224. The two tapered rollers 226 are symmetrically rotatably mounted on both sides of the lifting seat 224.

[0051] It should be noted that when the size of the stainless steel tube 4 changes, the adjusting rod 225 can be rotated to move the adjusting rod 225 up and down, thereby driving the lifting seat 224 to slide, so as to adjust the position of the tapered roller 226 and adapt to stainless steel tubes 4 of different sizes.

[0052] Please refer to Figure 11 The discharging mechanism 3 includes a base 31, a driving assembly 32 and two belt clamping assemblies 33. The driving assembly 32 is installed on the top of the base 31. The two belt clamping assemblies 33 are symmetrically arranged on one side of the driving assembly 32. The driving assembly 32 drives the two belt clamping assemblies 33 to move synchronously.

[0053] It should be noted that the above-mentioned belt clamping assembly 33 belongs to the existing technology, and the spacing between the two belt clamping assemblies 33 can be adjusted to adapt to stainless steel pipes 4 of different sizes. The two belt clamping assemblies 33 are driven to move synchronously by the driving assembly 32, and the two belt clamping assemblies 33 respectively clamp the upper and lower surfaces of the stainless steel pipe 4, thereby, on the one hand, being able to drive the stainless steel pipe 4 to move, and on the other hand, preventing the stainless steel pipe 4 from having relative positions during the movement.
