Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a welding device and a welding method for aluminum material processing with a heat dissipation function. Background Art

[0002] With the development of modern industry, aluminum and its alloy materials are widely used in aerospace, transportation, architectural decoration and other fields due to their light weight, high strength and good corrosion resistance. In the processing of aluminum materials, welding is a common connection method, which can firmly connect different parts together through welding equipment to ensure the integrity and functionality of the structure. Common welding equipment includes straight seam welding machine, argon arc welding machine, submerged arc welding machine, butt welding machine and other types according to the welding method.

[0003] The straight seam welding machine is an automated welding device used to automatically complete straight seams and is widely used in many fields of the manufacturing industry. It improves production efficiency and welding quality, reduces labor costs, and improves the working environment of welders through mechanization and automation technology. However, due to the physical properties of aluminum materials, the existing straight seam welding machines still have the following problems when welding aluminum materials:

[0004] 1. There is a dense oxide film on the surface of aluminum. The melting point of this oxide film is several hundred degrees higher than that of aluminum. It is also very inert and not easily destroyed. If the oxide film is not removed, it will affect the formation of the molten pool and cause weld defects. In the prior art, a separate process is required to remove the oxide film on the surface of aluminum, which reduces welding efficiency and increases the process flow of aluminum welding.

[0005] 2. Aluminum has a high thermal conductivity, which will cause rapid heat loss during welding, resulting in uneven or incomplete welds. Before welding, the aluminum should be properly preheated with a flame or electric heater to increase its temperature and plasticity. The preheating process not only further increases the process flow of aluminum welding, but also the heated aluminum will gradually cool down during the process from preheating to the start of welding, which may cause the preheating temperature to fail to meet the welding requirements.

[0006] 3. Aluminum has a large shrinkage, which will cause stress and deformation after welding. After welding, the aluminum should be properly cooled by natural cooling or water cooling to eliminate its stress and deformation. However, the existing straight seam welding machine cannot cool the weld in time. Most of them need to be cooled after the aluminum is welded and disassembled.

[0007] Based on the above problems, this application document proposes a welding device and a welding method for aluminum processing with heat dissipation function to improve the above problems. Summary of the invention

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0051] 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.

[0053] Please refer to the attached Figures 1 to 3 As shown, it is the first embodiment of the present invention, which provides a welding device for aluminum processing with heat dissipation function, including a straight seam welding body 10, on which a control module, a clamping assembly 11 and a driving assembly 12 are arranged, one side of the driving assembly 12 is equipped with a position adjustment assembly 13, one end of the position adjustment assembly 13 is equipped with a locking plate 14, and one end of the locking plate 14 is detachably equipped with a welding head 15, and further includes:

[0054] The grinding part 20 includes a guide rod 21, a bracket 22, an elastic element 23, a grinding motor 24 and a grinding roller 25. The guide rod 21 is slidably connected to the inside of the locking plate 14, the bracket 22 is fixed to the lower end of the guide rod 21, the elastic element 23 is assembled between the bracket 22 and the locking plate 14, the grinding motor 24 is assembled to the lower end of the bracket 22, and the grinding motor 24 and the control module are electrically connected through a wire, and the grinding roller 25 is assembled on the outside of the grinding motor 24;

[0055] The temperature regulating part 30 is assembled at one end of the locking plate 14. After the temperature regulating part 30 is in operation, it can preheat the aluminum joint and cool the weld.

[0056] In the initial state, the elastic element 23 is in a compressed state.

[0057] Furthermore, in the present embodiment, the aluminum joint refers to the joint where multiple aluminum materials need to be welded but have not been welded, and the aluminum weld refers to the connection portion formed after multiple aluminum materials are welded.

[0058] Furthermore, the grinding motor 24 is an existing mature technology, which at least includes a stator and a rotor. The stator is fixedly connected to the bracket 22, the rotor is rotatably connected to the outside of the stator, and the rotor is fixedly connected to the grinding roller 25. The grinding roller 25 is a special grinding element for aluminum alloy, and its material is alumina, which avoids the appearance of impurities such as sand particles during the grinding process, causing defects such as slag inclusions in the molten pool.

[0059] It should be noted that, in the present embodiment, the welding head 15 welds the aluminum material by laser welding, wherein a large amount of heat is generated during laser welding.

[0060] In this embodiment, the aluminum material is clamped and fixed by the clamping component 11, and the locking plate 14 is driven to move by the position adjustment component 13 so that the grinding roller 25 and the aluminum joint are tightly fitted, and the driving component 12 is started. The position adjustment component 13, the locking plate 14, the welding head 15, the grinding part 20 and the temperature adjustment part 30 are driven to move along the extension direction of the aluminum joint by the driving component 12, and the welding head 15 is started to perform laser welding on the aluminum joint, and the grinding motor 24 is started by the control module to make the grinding motor 24 run, and the grinding roller 25 is driven to rotate by the grinding motor 24, and the aluminum joint is polished by the grinding roller 25 to remove the oxide film on the surface of the aluminum material to prevent the oxide film from affecting the formation of the molten pool and causing weld defects. At the same time, the integrated grinding roller 25 can reduce the process flow during aluminum welding and improve welding efficiency.

[0061] Next, please refer to Figure 2 and Figure 3 As shown, a splash shield 26 is fixed to the upper end of the interior of the bracket 22 , and the splash shield 26 and the grinding roller 25 are matched.

[0062] In this embodiment, when the grinding motor 24 drives the grinding roller 25 to rotate to grind the oxide layer at the aluminum joint, the generated impurities such as aluminum powder and aluminum chips will splash along with the high-speed rotating grinding roller 25. The splash guard 26 can block the splashing aluminum powder and aluminum chips and make them fall onto the surface of the workpiece, thereby preventing the aluminum powder and aluminum chips from scattering onto the workbench.

[0063] Secondly, please also refer to Figures 3 to 6 The temperature regulating part 30 includes a guide air duct 31 and an air intake fan 32. The guide air duct 31 is fixed to one end of the locking plate 14. A U-shaped avoidance groove is provided at the bottom of the guide air duct 31, and the U-shaped avoidance groove is adapted to the welding head 15. The air intake fan 32 is fixed to the upper end of the guide air duct 31, and the air intake fan 32 and the control module are electrically connected through a wire. An air intake grille 33 is provided at the upper end of the outer side of the guide air duct 31, and the air intake grille 33 is adapted to the air intake fan 32. A partition plate is provided inside the guide air duct 31, and the inside of the guide air duct 31 is partitioned. The plate is separated into a preheating air duct 34 and a cooling air duct 35, and the cooling air duct 35 is located on one side of the preheating air duct 34. A first air outlet 36 is provided at one end of the preheating air duct 34 away from the air inlet grid 33, and the first air outlet 36 is adapted to the grinding roller 25. A plurality of second air outlets 37 are provided at one end of the guide air duct 31 away from the grinding roller 25 and located at the lower end of the cooling air duct 35. A flow regulating part 40 is installed inside the guide air duct 31, and the preheating air duct 34 and the flow regulating part 40 as well as the cooling air duct 35 and the flow regulating part 40 are adapted to each other.

[0064] In this embodiment, when laser welding is performed on aluminum, the welding head 15 releases a large amount of heat, and the air intake fan 32 is started. The air outside the guide air duct 31 is transported to the inside of the preheating air duct 34 and the cooling air duct 35 through the air intake fan 32. When the gas inside the preheating air duct 34 flows through the welding head 15, it absorbs heat and flows from the first air outlet 36 to the aluminum joint. The aluminum joint is preheated by the heated gas to increase the temperature and plasticity of the aluminum. The aluminum powder and aluminum chips generated by grinding can also be cleaned to avoid the aluminum joint. Aluminum powder and aluminum chips affect the quality of the weld. The above scheme not only reduces the process flow of aluminum welding, but also avoids the problem of temperature reduction from preheating to welding in the prior art. At the same time, the heat generated during laser welding can be recycled and reused, reducing process costs and improving resource utilization and welding efficiency. The gas inside the preheating duct 34 flows to the weld through the second air outlet 37, and the weld is cooled in time to eliminate stress in the weld, reduce the probability of weld deformation, and improve weld quality and welding effect.

[0065] Secondly, a plurality of filter elements (not shown in the figure) are fixed to the upper end of the interior of the air guide duct 31 , and the filter elements are matched with the air intake grid 33 .

[0066] In this embodiment, when the gas outside the air guide duct 31 enters the air guide duct 31 through the air intake grid 33, the setting of the filter element can filter impurities such as particles and dust in the gas to prevent impurities in the air from affecting the quality of the weld.

[0067] In a preferred embodiment, the guide air duct 31 is made of a high temperature resistant material, and a heat insulation coating is disposed inside the cooling air duct 35 .

[0068] In this embodiment, the selection of high temperature resistant materials can prevent the heat generated by the welding head 15 from causing deformation of the guide air duct 31. The provision of the thermal insulation coating can prevent the heat inside the preheating air duct 34 from being transferred to the cooling air duct 35, thereby preventing the gas inside the cooling air duct 35 from absorbing heat and raising the temperature, thereby ensuring the cooling effect on the weld.

[0069] Please refer again Figure 7 and Figure 8 As shown, the flow regulating part 40 includes a driving knob 41, a threaded rod 42 and an adjusting plate 43. The driving knob 41 is rotatably connected to one side of the air guide duct 31, the threaded rod 42 is threadedly connected to the inside of the driving knob 41, the adjusting plate 43 is rotatably connected to the upper end of the partition plate, and the threaded rod 42 and the adjusting plate 43 are rotatably connected.

[0070] In this embodiment, the driving knob 41 is rotated, and the driving knob 41 drives the threaded rod 42 to move and the adjusting plate 43 to rotate through the threaded connection between the driving knob 41 and the threaded rod 42 and the threaded connection between the threaded rod 42 and the adjusting plate 43, thereby adjusting the placement angle of the adjusting plate 43 inside the air guide duct 31. When the adjusting plate 43 rotates in the direction close to the driving knob 41, the gas flow inside the preheating air duct 34 increases, and the gas flow inside the cooling air duct 35 decreases, which can improve the preheating efficiency and preheating effect at the aluminum joint; when the adjusting plate 43 rotates in the direction away from the driving knob 41, the gas flow inside the preheating air duct 34 decreases, and the gas flow inside the cooling air duct 35 increases, which can improve the cooling efficiency at the weld. Through this arrangement, the staff can adjust the cooling efficiency or preheating efficiency according to the welding requirements.

[0071] Please refer again Figure 7 and Figure 8 The outer side of the threaded rod 42 is provided with a chamfered surface, and a plurality of scale marks are evenly arranged on the upper end of the chamfered surface. The end of the driving knob 41 away from the adjusting plate 43 is adapted to the scale mark.

[0072] Here, in the initial state, the angle between the adjustment plate 43 and the vertical direction is 0 degrees (ie, the air intake amounts inside the preheating air duct 34 and the cooling air duct 35 are equal).

[0073] It should be noted that, in the present embodiment, the scale mark is used to indicate the angle between the adjustment plate 43 and the vertical direction, and may also indicate the air intake ratio of the preheating air duct 34 or the cooling air duct 35 (the relationship between the air intake ratio and the scale mark can be determined through multiple tests). In the present embodiment, the scale mark is used to indicate the angle between the adjustment plate 43 and the vertical direction.

[0074] In this embodiment, by driving the end of the knob 41 away from the adjustment plate 43 and cooperating with the scale mark, the staff can easily identify and read the corresponding scale mark, which is convenient for the staff to adjust the air intake volume inside the preheating duct 34 or the cooling duct 35.

[0075] Furthermore, a plurality of anti-slip grooves are provided on the outer side of the driving knob 41 .

[0076] In this embodiment, the provision of the anti-slip pattern can increase the friction between the worker's hand and the driving knob 41, making it easier for the worker to apply force.

[0078] Determine the welding process parameters according to the welding requirements of aluminum materials. The welding process parameters include: welding speed, laser power, defocus, etc.;

[0081] The grinding motor 24 is started, and the grinding roller 25 is driven by the grinding motor 24 to rotate to grind the aluminum joint to remove the oxide film at the aluminum joint;

[0082] Start the welding head 15 to weld the aluminum joint;

[0083] The air intake fan 32 is started, and the gas medium is input into the preheating air duct 34 and the cooling air duct 35 through the air intake fan 32. The gas medium flowing through the cooling air duct 35 is heated by the welding head 15 and then flows to the aluminum joint through the first air outlet 36 to clean the aluminum joint. The gas medium flowing through the preheating air duct 34 flows to the aluminum weld through the second air outlet 37 to cool the weld.

[0084] The working principle of the present invention is:

[0085] The aluminum material is clamped and fixed by the clamping component 11, and the locking plate 14 is driven to move by the position adjustment component 13, so that the grinding roller 25 and the aluminum joint are closely fitted, and the driving component 12 is started, and the position adjustment component 13, the locking plate 14, the welding head 15, the grinding part 20 and the temperature adjustment part 30 are driven to move along the extension direction of the aluminum joint by the driving component 12, and the welding head 15 is started to perform laser welding on the aluminum joint, and the grinding motor 24 is started by the control module, and the grinding motor 24 drives the grinding roller 25 to rotate and grind the aluminum joint, so as to remove In order to remove the oxide film on the surface of the aluminum material, the air intake fan 32 is started, and the gas outside the guide air duct 31 is transported to the inside of the preheating air duct 34 and the cooling air duct 35 through the air intake fan 32. When the gas inside the preheating air duct 34 flows through the welding head 15, it absorbs heat and flows from the first air outlet 36 to the aluminum joint, and the aluminum joint is preheated by the heated gas. The gas inside the preheating air duct 34 flows to the weld through the second air outlet 37, and the weld is cooled in time to eliminate the stress in the weld, reduce the probability of deformation of the weld, and improve the weld quality and welding effect.

[0086] The above are only preferred embodiments of the present invention.
