Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to an aluminum alloy door and window frame welding equipment with an exhaust gas collection function. Background Art

[0002] The welding process of aluminum alloy door and window frames will produce harmful welding fumes and gases, such as ozone and nitrogen oxides, which will have a serious impact on the health of operators and the working environment. Therefore, it is necessary to develop an aluminum alloy door and window frame welding equipment with exhaust gas collection function, which can not only complete the welding operation efficiently, but also effectively collect and discharge the harmful exhaust gas generated during the welding process through the built-in exhaust gas collection pipe, so as to ensure the cleanliness and safety of the workshop environment.

[0003] The patent with patent publication number CN118752136A discloses a welding device for processing aluminum alloy doors and windows, including a support frame, a pre-storage frame fixedly connected to the upper end of the support frame, a processing table fixedly connected to the upper end of the pre-storage frame, a plurality of grooves and lifting grooves are provided on the upper end of the pre-storage frame, a pre-storage conveyor belt is provided in each groove, a frame body is placed on the upper end of the pre-storage conveyor belt, a lifting mechanism is provided in the lifting groove, a positioning mechanism and a welding mechanism are provided in the support frame, the positioning mechanism includes a plurality of first inclined grooves provided on the upper end face of the support frame, a first connecting rod is slidably connected in the first inclined groove, a positioning frame is fixedly connected to the upper end of the first connecting rod, a unloading mechanism is provided in the processing table and the pre-storage frame, and the present invention can control the frame body to fit around the processing table under the action of the pre-storage conveyor belt. When the frame body is lifted, the frame body can be automatically loaded and positioned under the action of the positioning mechanism.

[0004] The prior art has the following defects: Unable to effectively discharge waste gas generated during welding: Harmful welding fumes and gases, such as ozone and nitrogen oxides, will be generated during the welding of aluminum alloy door and window frames. If the waste gas generated during welding cannot be effectively discharged, the concentration of welding fumes and harmful gases (such as ozone and nitrogen oxides) in the workshop will increase significantly, causing turbid air. Operators will feel pungent, eye pain and difficulty breathing. The quality of the weld will also be affected, and defects such as pores and cracks will appear. If operators are exposed to such an environment for a long time, their health will be seriously threatened, and production efficiency and product quality will also decrease. Therefore, it is necessary to set up a closed welding box and a waste gas collection pipe connected to the inside of the welding box, so as to reduce the concentration of harmful gases in the workshop, protect the health of operators, meet environmental protection standards, create a good working environment, and achieve the effect of improving production efficiency and weld quality.

[0005] Unable to adapt to different welding methods of aluminum alloy door and window frames: The welding methods of aluminum alloy door and window frames are generally divided into right-angle welding and bevel welding. Among them, right-angle welding can provide strong structural stability, especially at the four corners of the door and window frames, which can effectively prevent deformation and is suitable for door and window products with high requirements on structural strength and appearance. Bevel welds usually have better fatigue resistance and are suitable for door and window products that bear dynamic loads for a long time. They are suitable for door and window products that need to improve fatigue resistance and crack resistance. When the welding equipment cannot adapt to different welding methods of aluminum alloy door and window frames, it will lead to unstable welding quality, cracks, pores or uneven welds. Therefore, it is necessary to set up a structure that can freely switch welding methods and ensure the sealing of the welding box, thereby improving the welding quality of aluminum alloy door and window frames, reducing welding defects, ensuring structural strength and aesthetics, and achieving the effect of improving production efficiency and reducing operation difficulty.

[0044] Through the setting of the clamping assembly 44, after the pressing assembly 43 is fixed, the clamping assembly 44 is operated, and the second hand wheel 441 is rotated to drive the two bidirectional threaded rods 443 to rotate synchronously in the corresponding threaded seats 444 through the second synchronous transmission belt 442. The threads at both ends of the bidirectional threaded rods 443 rotate in opposite directions, and the two first clamping blocks 445 and the two second clamping blocks 446 move in opposite directions accordingly, clamping the door and window frame 5 in the middle and fixing it, thereby playing the role of clamping and fixing.

[0045] During use, after the two door and window frames 5 in the welding box 1 are butted, the pressing assembly 43 is operated, the first hand wheel 432 is rotated to drive the two lifting threaded rods 434 to rotate synchronously on the support frame 411 through the first synchronous transmission belt 433, and the lower pressing plate 431 moves downward to overlap and fix the top of the door and window frame 5, and then the clamping assembly 44 is operated, the second hand wheel 441 is rotated to drive the two bidirectional threaded rods 443 to rotate synchronously in the corresponding threaded seat 444 through the second synchronous transmission belt 442, and the threads at both ends of the bidirectional threaded rod 443 rotate in opposite directions, and the two first clamping blocks 445 and the two second clamping blocks 446 move in opposite directions, clamping the door and window frame 5 in the middle and fixing it, so as to play a role of stable clamping and fixing. The rest of the structure is the same as that of Example 1.

[0046] Working principle of the present invention: During operation, the fixing mechanism 4 is adjusted according to the welding method of the aluminum alloy door and window frame.

[0047] When the welding method is right-angle welding, one of the support frames 411 is in the movable opening 32 on the side, and the other support frame 411 is at a right angle thereto. The multiple door sealing blocks 353 in the corresponding movable opening 32 are lifted in the lifting groove 31 through the handle 351 and the penetration rod 352, and the two door and window frames 5 are pushed into the welding box 1 along the two guide rails 415. The handle 351 is then lowered, and the door sealing blocks 353 are slidably connected with the penetration rod 352 through the penetration groove 354. Thus, the multiple door sealing blocks 353 fall freely and are respectively placed on the door and window frames 5 and the movable opening 32 for sealing. The two door and window frames 5 in the welding box 1 are butt-jointed at a right angle.

[0048] Then, the pressing assembly 43 is operated, and the first hand wheel 432 is rotated to drive the two lifting threaded rods 434 to rotate synchronously on the support frame 411 through the first synchronous transmission belt 433, and the pressing plate 431 moves downward to overlap the top of the door and window frame 5 and is fixed.

[0049] Then operate the clamping assembly 44, rotate the second hand wheel 441 to drive the two bidirectional threaded rods 443 to rotate synchronously in the corresponding threaded seats 444 via the second synchronous transmission belt 442, and the threads at both ends of the bidirectional threaded rods 443 rotate in opposite directions, and the two first clamping blocks 445 and the two second clamping blocks 446 move in opposite directions accordingly, clamping the door and window frame 5 in the middle and fixing it.

[0050] Finally, the automatic welding device 6 is operated. The automatic welding device 6 moves horizontally and vertically in the welding movable groove 61, and the automatic welding device 6 itself can move in multiple axes to automatically weld the right angles where the two door and window frames 5 are connected. The exhaust gas generated during welding is discharged from the exhaust gas collection pipe 2 connected to the welding box 1 to the purification device, thereby completing welding and exhaust gas collection.

[0051] When the welding method is bevel welding, the sealing block 353 is lifted by the handle 351, and one of the support frames 411 is pushed into the second movable opening 32 on the side. When the support frame 411 moves, the driving wheel 414 drives one end of the support frame 411 to rotate through the support rod 413, and the guide rod 412 at the bottom of the other end of the support frame 411 rotates in the arc groove 42, and when the support frame 411 slides in the sliding groove 34, the pushing block 416 on the support frame 411 will push the sealing teeth 36 in the card groove 33 to slide upward, and the support frame 411 falls after passing through the rear sealing teeth 36 to play a sealing role, and the other support frame 411 is at a right angle to it to complete the movement.

[0052] Then, the two door and window frames 5 are pushed into the welding box 1 along the two guide rails 415, so that the two door and window frames 5 are butted at an oblique angle in the welding box 1, and then the automatic welding device 6 is operated to perform automatic welding operations. The welding method is not limited to right-angle welding and oblique-angle welding. Automatic welding can be performed for both acute angles and obtuse angles of special-shaped door and window frames 5, and it is only necessary to adjust the angle between the two support frames 411.
