Description

Technical Field

[0001] The present invention relates to the technical field of industrial pipeline construction, and more particularly to an argon arc welding machine for industrial pipeline construction. Background Art

[0002] Argon arc welding machines are essential for welding pipes together during industrial pipeline construction. Using argon as a shielding gas, an arc is generated between a non-melting electrode and the workpiece. The high temperature of the arc melts the base metal, achieving a strong weld between the pipes. Argon arc welding machines play a vital role in industrial pipeline construction due to their high weld quality, aesthetically pleasing weld seams, and strong adaptability.

[0003] When using an argon arc welder to weld pipes, argon is used as a shielding gas during the welding process. During this process, argon is directly discharged into the working environment. If the processing environment is relatively closed, it is easy to cause the argon content in the processing environment air to exceed the standard, resulting in hypoxia. In addition, the welding process may produce a large amount of dust particles, toxic gases (such as ozone and nitrogen oxides), and smoke. Long-term inhalation of these harmful substances can irritate the respiratory tract and lungs, leading to lung diseases. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 4 , an argon arc welding machine for industrial pipeline construction, including an equipment support 1 and a welding head 2, the equipment support 1 is provided with a gas supply component and a power supply component for providing power and argon required for the welding process, an argon processing mechanism, the argon processing mechanism is arranged on the upper surface of the equipment support 1, the argon processing mechanism includes a welding mask 301 fixedly connected to the equipment support 1, the welding mask 301 can be used to shield the argon and harmful substances generated during the welding process, the welding head 2 is fixedly connected to the inner top of the welding mask 301, the bottom end of the welding mask 301 is connected to a frame 303, the lower end of the frame 303 is connected to an exhaust pipe 302, and the harmful substances and argon can be transported to a designated location through the exhaust pipe 302.

[0035] Among them, the interior of the frame 303 is fixedly connected to an exhaust fan 304, and the harmful substances and argon gas in the welding mask 301 can be transported to the exhaust pipe 302 through the exhaust fan 304. The exhaust fan 304 is used to transport the gas and smoke generated during the welding process. Two observation windows 305 are provided on the top of the welding mask 301. The welding status of the internal pipes of the welding mask 301 can be observed through the observation windows 305. Filters are fixedly connected to the two observation windows 305, and the filters can reduce the impact of the strong light generated during the welding process on the eyesight of surrounding workers.

[0036] By adopting the above technical solution, when using argon arc welding to weld pipelines, the two pipelines to be welded are inserted from both sides of the welding mask 301 so that the weld to be welded between the two pipelines is directly below the welding head 2. The welding of the two pipelines can be achieved by the welding head 2. The argon gas and harmful substances generated during the welding process can be shielded by the welding mask 301 to prevent these substances from being directly exposed to the working environment, prevent the argon gas content in the processing environment air from exceeding the standard and causing hypoxia, and prevent harmful substances from leaking and being inhaled by workers. When using the welding mask 301 to prevent these substances from flowing out, the exhaust fan 304 composed of the power component and fan blades is used to transport the harmful substances and argon gas in the welding mask 301 to the exhaust pipe 302, and the harmful substances and argon gas are transported to a designated location through the exhaust pipe 302, thereby preventing the harmful substances and argon gas inside the welding mask 301 from accumulating over time and leaking.

[0037] like Figure 1-Figure 7As shown, the welding auxiliary mechanism is arranged on both sides of the welding mask 301, and the welding auxiliary mechanism includes two supporting vertical plates 405 fixedly connected to the two ends of the top of the welding mask 301, and the interiors of the two supporting vertical plates 405 are rotatably connected to the first screw 403 and the second screw 404, respectively. The thread directions of the first screw 403 and the second screw 404 are opposite, and the two abutment plates 507 can be synchronously moved in the direction of approaching each other when the first screw 403 and the second screw 404 rotate. The surfaces of the first screw 403 and the second screw 404 are both provided with a connecting seat 402, and the interior of the connecting seat 402 is provided with a slider 413 and a sliding The plate 412, the two sliders 413 are respectively threadedly sleeved on the surfaces of the first screw 403 and the second screw 404, one of the connecting seats 402 is fixedly connected to the surface of the motor 401, and the active driving wheel 408 can be driven to rotate by the motor 401, and the output shaft of the motor 401 is fixedly connected to the active rotating shaft 410, and the surface of the active rotating shaft 410 is fixedly sleeved with the active driving wheel 408. When the active driving wheel 408 rotates, it will synchronously drive the pipeline to rotate, so that the weld path of the pipeline passes through the welding head 2, thereby realizing complete welding of the pipeline weld, and the first screw 403 and the second screw 404 are fixedly connected to the first handle 411 at one end close to each other.

[0038] Among them, a connecting rod 407 is fixedly connected between the first screw 403 and the second screw 404. Through the connecting rod 407, when any one of the first turning handles 411 is rotated, the first screw 403 and the second screw 404 can be synchronously driven to rotate, thereby improving the convenience of operation. The two longitudinal walls of the two connecting seats 402 are each provided with two sliding grooves, and the slide 412 and the slider 413 are respectively slidably connected to the inside of the two sliding grooves. Two telescopic rods 406 are fixedly inserted into the inside of both sides of the welding mask 301, and the ends of the two groups of telescopic rods 406 away from each other are respectively fixedly connected to the two slides 412.

[0039] Among them, the surface of the motor 401 is fixedly connected to the bracket 501, the outer arc surface of the bracket 501 is fixedly connected to three branch arms 503, the surface of the branch arm 503 is fixedly connected to the guide plate 502, the surfaces of the three guide plates 502 are slidably sleeved with guide blocks 508, one end of the three guide blocks 508 are respectively rotatably connected to the driving shaft 410 and two driven shafts 414, the surfaces of the two driven shafts 414 are sleeved with driven driving wheels 409, the cross-sectional shape of the bracket 501 is arc-shaped, the surfaces of the three guide blocks 508 are fixedly connected to the rack 504, the surface of the bracket 501 is fixedly connected to the support frame 506, the middle part of the support frame 506 is threadedly inserted with a positioning screw 511, the positioning screw 511 can drive the gear 505 to rotate, and the friction between the positioning screw 511 and the support frame 506 can fix it when the gear 505 rotates to any state.

[0040] Among them, the positioning screw 511 is fixedly connected to the connecting shaft 510 at one end close to the welding mask 301, and the surface of the connecting shaft 510 is fixedly sleeved with a gear 505, which is engaged with the three racks 504. The gear 505 drives the three racks 504 to move, so that the active drive wheel 408 and the two driven drive wheels 409 can clamp the pipe, so that the axis of the pipe can always be in a fixed position when it rotates horizontally each time the pipe is welded. The end of the positioning screw 511 away from the connecting shaft 510 is fixedly connected to the second turning handle 509, and the end of the connecting shaft 510 close to the welding mask 301 is rotatably connected to the abutment disk 507. The two abutment disks 507 respectively abut one end of the two pipes to fix the pipe, and the weld is just below the welding head 2.

[0041] By adopting the above technical solution, when welding the pipeline, the pipeline is moved from the bottom of the bracket 501 to align with the two sides of the welding mask 301, and then the pipeline is inserted into the welding mask 301 to complete the preparation work for pipeline welding. Then, the active drive wheel 408 is driven to rotate by the motor 401. Since the active drive wheel 408 and the two driven drive wheels 409 are in close contact with the surface of the pipeline, when the active drive wheel 408 rotates, the two driven drive wheels 409 are also driven to rotate synchronously, thereby driving the pipeline to rotate, so that the weld path of the pipeline passes through the welding head 2, and complete welding of the pipeline weld can be achieved.

[0042] After the pipe is inserted into the welding mask 301, the first screw 403 and the second screw 404 are driven to rotate. Since the thread directions of the first screw 403 and the second screw 404 are opposite, the two abutment plates 507 can be moved synchronously in the direction of approaching each other until the two abutment plates 507 respectively abut against the ends of the two pipes that are away from each other, thereby fixing the pipes and making the weld between the two pipes of the same length just below the welding head 2. Every time the pipes are welded, the weld of the pipes can be kept in a fixed position, thereby achieving precise positioning of the pipes.

[0043] When the pipe is inserted into the welding mask 301 to be welded, the positioning screw 511 can be rotated to synchronously drive the gear 505 to rotate. When the gear 505 rotates, it will also drive the three racks 504 to move, thereby pulling the active drive wheel 408 and the two driven drive wheels 409 to move synchronously in the direction of approaching each other, so that the active drive wheel 408 and the two driven drive wheels 409 can clamp the pipe. Each time the pipe is welded, the axis of the pipe can always be in a fixed position when it rotates horizontally, thereby achieving precise positioning of the rotation axis of the pipe and maintaining the stability of the axis when the pipe rotates.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
