Description

Technical Field

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

[0002] In the construction of industrial pipelines, argon arc welding machines are needed to achieve the welding work between pipelines. The argon arc welding machine uses argon as a shielding gas, generates an arc between the non-melting electrode and the workpiece, and melts the metal base material under the high temperature of the arc, thereby achieving a firm welding between the pipelines. The argon arc welding machine plays an important role in the field of industrial pipeline construction due to its high welding quality, beautiful welds, 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 air of the processing environment to exceed the standard and cause hypoxia. In addition, more dust particles, toxic gases (such as ozone, nitrogen oxides, etc.) and smoke may be generated during the welding process. Long-term inhalation of these harmful substances will irritate the respiratory tract and lungs, leading to lung diseases. Summary of the invention

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0007] Furthermore, an exhaust fan is fixedly connected to the interior of the frame, and the exhaust fan is used to transport the gas and smoke generated during the welding process.

[0008] Furthermore, two observation windows are arranged on the top of the welding shield.

[0009] Furthermore, filters are fixedly connected to the two observation windows.

[0010] Furthermore, a welding auxiliary mechanism is provided on both sides of the welding mask, and the welding auxiliary mechanism includes two supporting vertical plates fixedly connected to the two ends of the top of the welding mask, and the first screw and the second screw are rotatably connected inside the two supporting vertical plates respectively, and the thread directions of the first screw and the second screw are opposite, and the surfaces of the first screw and the second screw are both sleeved with a connecting seat, and a slider and a slide are provided inside the connecting seat, and the two sliders are respectively threadedly sleeved on the surfaces of the first screw and the second screw, and the surface of one of the connecting seats is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to an active rotating shaft, and the surface of the active rotating shaft is fixedly sleeved with an active driving wheel, and the ends of the first screw and the second screw close to each other are fixedly connected to a first rotating handle.

[0011] Furthermore, a connecting rod is fixedly connected between the first screw rod and the second screw rod.

[0012] Furthermore, two longitudinal walls of the two connecting seats are provided with two sliding grooves, the sliding plate and the sliding block are respectively slidably connected to the inside of the two sliding grooves, two telescopic rods are fixedly inserted inside both sides of the welding mask, and the ends of the two groups of telescopic rods away from each other are respectively fixedly connected to the two sliding plates.

[0013] Furthermore, a bracket is fixedly connected to the surface of the motor, three branch arms are fixedly connected to the outer arc surface of the bracket, a guide plate is fixedly connected to the surface of the branch arm, guide blocks are slidably sleeved on the surfaces of the three guide plates, a driving shaft and two driven shafts are rotatably connected inside one end of the three guide blocks, driven driving wheels are sleeved on the surfaces of the two driven shafts, and the cross-sectional shape of the bracket is arc-shaped.

[0014] Furthermore, the surfaces of the three guide blocks are fixedly connected with racks, the surface of the bracket is fixedly connected with a support frame, a positioning screw is threadedly inserted into the middle of the support frame, an end of the positioning screw close to the welding mask is fixedly connected to a connecting shaft, a gear is fixedly sleeved on the surface of the connecting shaft, the gear is meshed with the three racks, and an end of the positioning screw away from the connecting shaft is fixedly connected to a second turning handle.

[0015] Furthermore, an end of the connecting shaft close to the welding shield is rotatably connected to an abutment disk.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (2) This solution utilizes an exhaust fan to extract harmful substances and argon gas accumulated in the welding hood into an exhaust pipe and directs them to a predetermined safe discharge area, thereby effectively preventing these substances from accumulating over time inside the welding hood, thereby avoiding the risk of overflow or leakage and further improving the safety of the operating environment.

[0019] (3) After the pipe is inserted into the welding mask, the first screw and the second screw are used to make the two abutment plates fit together and fix the two pipes of equal length, ensuring that the weld between the pipes can be aligned directly below the welding head. Therefore, the pipe weld can be fixedly positioned during each welding operation, ensuring the precise positioning and stability of the pipe welding.

[0020] (4) In this solution, when the pipe is inserted into the welding mask and prepared for welding, the three racks are moved synchronously through the gears, thereby driving the active drive wheel and the two driven drive wheels to move in a coordinated direction towards each other, thereby achieving a stable clamping of the pipe, ensuring that during each welding process, when the pipe rotates horizontally, its axis can always remain in a fixed position, thereby achieving the positioning of the pipe rotation axis, ensuring the axis stability of the pipe during rotation, and further improving the precise positioning and stability of pipe welding.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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 creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 4 A argon arc welding machine for industrial pipeline construction includes 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, and an argon gas processing mechanism. The argon gas processing mechanism is arranged on the upper surface of the equipment support 1. The argon gas 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 gas 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. The harmful substances and argon gas can be transported to a designated position through the exhaust pipe 302.

[0035] Among them, the interior of the frame 303 is fixedly connected with 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 set on the top of the welding mask 301. The welding status of the internal pipeline of the welding mask 301 can be observed through the observation windows 305. Filters are fixedly connected to the two observation windows 305. The filters can reduce the impact of the strong light generated during the welding process on the eyesight of the surrounding staff.

[0036] By adopting the above technical solution, when the pipeline is welded by argon arc welding, 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 under the welding head 2, and the welding of the two pipelines can be achieved by the welding head 2 used for welding. The argon gas and harmful substances generated during the welding process can be shielded by the welding mask 301, so as to prevent these substances from being directly exposed to the working environment, prevent the argon gas content in the air of the processing environment from exceeding the standard and causing hypoxia, and prevent harmful substances from leaking and being inhaled by the staff. When the welding mask 301 is used to prevent these substances from flowing out, the exhaust fan 304 composed of the power component and the 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 the designated position through the exhaust pipe 302, so as to prevent the harmful substances and argon gas inside the welding mask 301 from accumulating over time and overflowing and leaking.

[0037] like Figure 1-Figure 7As shown, a welding auxiliary mechanism is arranged on both sides of the welding mask 301, and the welding auxiliary mechanism includes two supporting upright plates 405 fixedly connected to the two ends of the top of the welding mask 301, and the interiors of the two supporting upright plates 405 are rotatably connected with a first screw 403 and a second screw 404 respectively, and 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 a direction close to each other when the first screw 403 and the second screw 404 rotate, and the surfaces of the first screw 403 and the second screw 404 are both sleeved with a connecting seat 402, and the interior of the connecting seat 402 is provided with a slider 413 and a slider The two sliders 413 are respectively threadedly sleeved on the surfaces of the first screw rod 403 and the second screw rod 404, wherein the surface of one of the connecting seats 402 is fixedly connected with a 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 with an active rotating shaft 410, and the surface of the active rotating shaft 410 is fixedly sleeved with an active driving wheel 408, and 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, and complete welding of the pipeline weld is achieved, and the first screw rod 403 and the second screw rod 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. Two longitudinal walls of the two connecting seats 402 are each provided with two sliding grooves, and the sliding plate 412 and the sliding block 413 are respectively slidably connected to the inside of the two sliding grooves, and 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 sliding plates 412.

[0039] Among them, a bracket 501 is fixedly connected to the surface of the motor 401, three branch arms 503 are fixedly connected to the outer arc surface of the bracket 501, and a guide plate 502 is fixedly connected to the surface of the branch arm 503. The surfaces of the three guide plates 502 are slidably sleeved with guide blocks 508, and one end of the three guide blocks 508 are rotatably connected to the inside of a driving shaft 410 and two driven shafts 414, and 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, and the surfaces of the three guide blocks 508 are fixedly connected to racks 504. The surface of the bracket 501 is fixedly connected to a support frame 506, and a positioning screw 511 is threadedly inserted in the middle part of the support frame 506. 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 the gear 505 when it rotates to any state.

[0040] Among them, the end of the positioning screw 511 close to the welding mask 301 is fixedly connected to the connecting shaft 510, and the surface of the connecting shaft 510 is fixedly sleeved with a gear 505, which is meshed with the three racks 504. The gear 505 drives the three racks 504 to move, so that the active driving wheel 408 and the two driven driving wheels 409 can clamp the pipeline, so that the axis of the pipeline can always be in a fixed position when it rotates horizontally each time the pipeline is welded. The end of the positioning screw 511 away from the connecting shaft 510 is fixedly connected to the second rotating handle 509, and the end of the connecting shaft 510 close to the welding mask 301 is rotatably connected to the abutment plate 507. The two abutment plates 507 respectively abut one end of the two pipelines to fix the pipeline, 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 driving wheel 408 is driven to rotate by the motor 401. Since the active driving wheel 408 and the two driven driving wheels 409 are both in close contact with the surface of the pipeline, when the active driving wheel 408 rotates, the two driven driving wheels 409 are also driven to rotate synchronously, which can drive the pipeline to rotate, so that the weld path of the pipeline passes through the welding head 2, and the 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 synchronously moved 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, so as to fix the pipe and make the weld between the two pipes of the same length just under the welding head 2. Every time the pipe is welded, the weld of the pipe can be in a fixed position, so as to achieve precise positioning of the pipe.

[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, and when the gear 505 rotates, it will also drive the three racks 504 to move, thereby pulling the active driving wheel 408 and the two driven driving wheels 409 to move synchronously in the direction of approaching each other, so that the active driving wheel 408 and the two driven driving wheels 409 can clamp the pipe, and each time the pipe is welded, the axis of the pipe can always be in a fixed position when it rotates horizontally, so as to achieve accurate positioning of the rotation axis of the pipe and maintain the stability of the axis when the pipe rotates.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
