[0039] See also Figure 1-10 Double-sided controlled butt weld forming, also known as double-sided welding or double-side welding, is a welding process in which both sides of the weld are controlled. This process is often used in applications requiring high weld quality, such as pressure vessels, pipelines, ship structures, and heavy machinery.

[0040] During the welding process, the materials to be welded need to be kept stable, and the spacing between them needs to be adjustable according to actual needs. In addition, the cooling of the weld after welding also determines the quality of the welding. Existing welds are generally cooled naturally after welding, and the adjustment of the fixed components during the welding process is not convenient. During welding, welding slag is easy to fall and splash, causing certain dangers. Based on this, a double-sided welding assembly for butt welds is proposed, including a mobile frame 1 for mobile welding and a clamping assembly 3 installed below the mobile frame 1;

[0041] The clamping assembly 3 includes a support base 32, a movable rail 31 is provided on the top of the support base 32, a clamping member 33 is slidably connected to the top of the movable rail 31, and the welding material 2 is provided between the two clamping members 33;

[0042] The clamping member 33 includes an arc-shaped plate 331, a supporting plate 333 is provided below the arc-shaped plate 331, a circular plate 334 is provided at one end of the arc-shaped plate 331 and the supporting plate 333, a connecting seat 336 is provided at one end of the top of the circular plate 334, and a slide rail is provided below the connecting seat 336;

[0043] One or more threaded holes 332 are formed on the top of the arc-shaped plate 331 and fasteners are installed thereon. The fasteners are used to adjust the position of the arc-shaped plate 331 on the circular plate 334 and to clamp the welding material 2 .

[0044] The mobile frame 1 is the supporting structure of the entire welding system and is typically made of sturdy metal to ensure its stability and durability. The mobile frame 1 is equipped with a drive device (such as an electric motor or gear transmission system) to realize the movement function of the components, so that the welding area can be accurately positioned and moved during the welding process.

[0045] The support base 32 is the base of the clamping assembly 3 and has a stable structure capable of withstanding the load generated during welding. A movable rail 31 is mounted on the top of the support base 32 for supporting and moving the clamping member 33.

[0046] The movable rail 31 is a horizontally mounted track that allows the clamping member 33 to slide along its length. Slide rails are mounted on the movable rail 31 so that the clamping member 33 can move freely during welding.

[0047] The main part of the clamping member 33 is an arc-shaped plate 331 . The shape of the arc-shaped plate 331 is designed to be in contact with the welding material 2 so as to be able to tightly clamp the welding material 2 .

[0048] The supporting plate 333 disposed below the arc-shaped plate 331 provides additional support, so that the arc-shaped plate 331 can clamp the welding material 2 more stably.

[0049] A circular plate 334 is provided at one end of the arc-shaped plate 331 and the supporting plate 333 . The circular plate 334 serves to provide a solid foundation so that the clamping member 33 can be stably fixed in an appropriate position during welding.

[0050] A connecting seat 336 is provided at one end of the top of the circular plate 334 , and a slide rail is provided below the connecting seat 336 . The connecting seat 336 is used to fix the clamping member 33 on the movable rail 31 so that the clamping member 33 remains stable when sliding.

[0051] The top of the arc-shaped plate 331 is provided with one or more threaded holes 332 for installing fasteners. The arrangement of the threaded holes 332 makes it more flexible to adjust the position of the arc-shaped plate 331.

[0052] The fasteners installed in the threaded holes 332 are used to adjust the position of the arc plate 331 relative to the circular plate 334 and to clamp the welding material 2. By adjusting the tightness of the fasteners, welding materials 2 of different sizes and shapes can be effectively clamped.

[0053] During use, the welding material 2 is placed between the two clamps 33. The fasteners are adjusted to ensure that the curved plate 331 accurately holds the welding material 2. The position of the clamps 33 on the movable rail 31 is also adjusted to ensure that the double-sided welding requirements of the butt weld are met. During welding, the clamp assembly 3 provides stable support and accurate positioning, thereby ensuring weld quality.

[0054] By using the clamping structure composed of the arc plate 331 and the supporting plate 333 , the welding material 2 can be stably clamped during the welding process to prevent the material from moving or displacing during the welding process.

[0055] The design of the fastener and the threaded hole 332 enables the clamping member 33 to be adjusted according to the size and shape of the welding material 2 , thereby increasing the flexibility and adaptability of the clamping assembly 3 .

[0056] By precisely adjusting the position and clamping force of the clamping member 33 , the stability of the welding material 2 during the welding process can be ensured, thereby improving the quality and consistency of the weld joint.

[0057] The design of the movable frame 1 allows the clamping assembly 3 to slide along the track, which facilitates the positioning and adjustment of the welding workpiece and improves the efficiency and convenience of the operation.

[0058] The automated clamping and moving system reduces the need for manual operation, reduces labor intensity, and improves the safety of the overall welding process.

[0059] A sliding groove 335 is formed in the middle of one side of the circular plate 334 located between the arc-shaped plate 331 and the supporting plate 333 . The sliding groove 335 is adapted to the arc-shaped plate 331 and the supporting plate 333 .

[0060] A receiving assembly 4 and a control assembly 5 are provided between the two clamping assemblies 3 . The control assembly 5 includes a double-rod motor and a threaded rod. The threaded rod is adapted to the connecting seat 336 .

[0061] Circular plate 334 is located in the middle of one side of curved plate 331 and support plate 333. Circular plate 334 is designed to include a slide groove 335, which runs radially along circular plate 334 and aligns with the structure of curved plate 331 and support plate 333. Slide groove 335 provides a precise guide channel, ensuring stable sliding and positioning of curved plate 331 and support plate 333.

[0062] The cooperation between the slide groove 335 , the arc plate 331 and the supporting plate 333 enables the arc plate 331 to move smoothly in the slide groove 335 when adjusting the clamping position, thereby ensuring accurate adjustment and stable clamping of the clamping member 33 .

[0063] The support assembly 4 is arranged between the two clamping assemblies 3. Its main function is to provide additional support and positioning to ensure that the clamping assembly 3 can be stably fixed in the desired position during the welding process. The support assembly 4 usually includes a support frame or support plate that can withstand the forces generated during the welding process.

[0064] The design of the receiving assembly 4 should take into account the size and weight of the welding material 2 to ensure that it can provide sufficient stability and support during the welding process.

[0065] The double-rod motor is used to accurately control the position of the clamping member 33. The double-rod motor has high control accuracy and stability, and can achieve accurate movement and adjustment of the clamping member 33.

[0066] The installation position and driving mode of the motor need to be compatible with the design of the clamping assembly 3 to ensure its high efficiency and reliability during operation.

[0067] The threaded rod is used to adjust the clamping force of the clamping assembly 3. The threaded rod is adapted to the connecting seat 336. By rotating the threaded rod, the fastening force of the clamping member 33 can be adjusted to adapt to welding materials 2 of different sizes and shapes.

[0068] The design of the threaded rod needs to take into account the load capacity and adjustment accuracy to ensure its stability and reliability in actual use.

[0069] The connecting seat 336 is used to connect the threaded rod with other parts of the clamping assembly 3 to ensure the stability and positioning accuracy of the clamping member 33 during the adjustment process.

[0070] The design of the connecting seat 336 needs to ensure a firm connection with the threaded rod and the clamping assembly 3 to avoid unstable connection due to vibration or load changes.

[0071] The design of the sliding groove 335 on the circular plate 334 can ensure that the arc plate 331 and the supporting plate 333 move smoothly during the clamping process, thereby improving the positioning accuracy of the clamping member 33.

[0072] The receiving assembly 4 provides additional support to ensure that the clamping assembly 3 remains stable during the welding process, reduces the movement and displacement of the clamping member 33, and further improves the welding quality.

[0073] Through the combination of the double-rod motor and the threaded rod, precise control of the clamping force can be achieved to adapt to welding materials of different sizes and shapes, thereby improving the adaptability and flexibility of the clamping.

[0074] The use of the dual-rod motor can automate the adjustment process of the clamping member 33, reducing the complexity and labor intensity of manual adjustment, making the operation more convenient and efficient.

[0075] Stable clamping and precise force control help improve the quality of welded joints, reduce welding defects, and ensure welding reliability and consistency.

[0076] The cooperation between the receiving component 4 and the control component 5 optimizes the performance of the entire welding system and improves the stability, precision and ease of operation of the system.

[0077] The receiving assembly 4 includes a receiving tray 41 and a telescopic member 42 . The telescopic member 42 is arranged on the top of the double-rod motor.

[0078] The support tray 41 includes a support box 413 . Air outlet plates 411 are provided on both sides of the top of the support box 413 . The air outlet plates 411 are provided with one or more air outlet holes 414 for cooling the weld.

[0079] Mounting grooves 412 are provided on both sides of the inner wall of the supporting box 413 , and cold air components 6 are installed in the mounting grooves 412 for forming cold air to be discharged from the air outlet plate 411 .

[0080] A downwardly recessed supporting area 415 is provided in the middle of the supporting box 413 for receiving welding slag.

[0081] The support box 413 is the main part of the support tray 41, which is used to provide stable support and receive welding slag during the welding process. The design of the support box 413 takes into account the high temperature and welding slag generated during the welding process to ensure its high temperature resistance and corrosion resistance.

[0082] The middle part of the supporting box 413 is provided with a downwardly recessed supporting area 415. This design can effectively collect the welding slag generated during the welding process, prevent the welding slag from falling on other components, and keep the welding area clean.

[0083] Air outlet plates 411 are provided on both sides of the top of the support box 413. The air outlet plates 411 have one or more air outlet holes 414. These air outlet holes 414 are used to cool the weld during welding to control the temperature of the weld zone and reduce the width of the heat-affected zone.

[0084] Mounting slots 412 are provided on both sides of the inner wall of the support box 413, and a cold air assembly 6 is installed at the mounting slots 412. The cold air assembly 6 is used to generate cold air, which is discharged through the air outlet holes 414 of the air outlet plate 411, thereby effectively cooling the welding area.

[0085] The design of the cold air component 6 should take into account the flow rate and wind speed of the cold air to ensure that the weld temperature can be effectively reduced and problems caused by overheating during the welding process, such as weld deformation or welding defects, can be prevented.

[0086] A telescopic member 42 is mounted on top of the dual-rod motor and is used to adjust the height and position of the support tray 41. Adjusting the telescopic member 42 allows precise control of the distance between the support tray 41 and the welding material 2 during welding, ensuring that the welding material 2 is stably placed within the support area 415.

[0087] The telescopic member 42 is used in conjunction with the dual-rod motor to allow height adjustment as needed during the welding process, thereby providing flexible operating space and precise control.

[0088] In actual use, the support box 413 of the support tray 41 collects welding slag produced during the welding process and simultaneously blows cool air toward the weld seam through the air outlet 414, helping to cool the weld and control the welding temperature. The adjustable function of the telescopic member 42 allows the operator to adjust the position of the support tray 41 according to the actual situation of the welding material 2, ensuring stability and cooling of the welding area.

[0089] The downwardly recessed supporting area 415 of the supporting box 413 can effectively collect welding slag generated during the welding process, thereby preventing the welding slag from affecting other components and keeping the working area clean.

[0090] The coordinated design of the air outlet holes 414 on the air outlet plate 411 and the cold air assembly 6 achieves effective cooling of the weld area, controls the welding temperature, reduces the occurrence of welding defects, and improves the welding quality.

[0091] The design of the telescopic member 42 enables the height of the tray 41 to be adjusted according to actual needs, thereby enhancing the adaptability and flexibility of the system and facilitating the processing of welding materials 2 of different sizes and shapes.

[0092] By precisely controlling the temperature of the weld and keeping the welding area clean, it helps to improve the quality of the weld joint, reduce welding defects, and ensure the consistency and reliability of the welding effect.

[0093] The combined design of the support box 413 and the cold air assembly 6 not only improves the stability during the welding process, but also effectively handles the heat load and welding slag problems during the welding process, thereby optimizing the overall performance of the entire welding system.

[0094] Through the effective slag collection and cooling system, the wear and tear of equipment and the frequency of cleaning are reduced, thus reducing maintenance costs and operating difficulties.

The legs 11 are typically made of high-strength metal materials with good load-bearing capacity.

[0097] The design of the support bracket 11 needs to take into account the various forces generated during the welding process, such as welding heat and mechanical vibration. The bottom of the bracket 11 may be equipped with an adjustment screw to achieve horizontal adjustment of the frame.

[0098] A crossbar 12 is provided between the two supporting legs 11 to connect the legs 11 and provide additional stability. The function of the crossbar 12 is to fix the legs 11 together to form a stable frame structure.

[0099] Crossbar 12 is usually made of high-strength metal material to withstand the various forces in the welding process. During design, it is necessary to ensure the strength and rigidity of crossbar 12 to avoid deformation or displacement during the welding process.

[0100] The gantry 14 is arranged on the top of the support frame 11 and spans the width of the entire frame. The main function of the gantry 14 is to provide a mounting platform for the welding arm 13 so that the welding arm 13 can operate in the welding area.

[0101] The design of the gantry 14 needs to ensure that it is strong enough to bear the weight of the welding arm 13 and the load generated during operation. The gantry 14 may be equipped with slide rails or guide rails so that the welding arm 13 can move in the welding area.

[0102] The welding arm 13 is mounted on the gantry 14 and is used to weld the welding material 2. The design of the welding arm 13 includes a welding power supply, a welding gun and a control system, which can accurately control the motion trajectory and welding parameters during the welding process.

[0103] The design of the welding arm 13 should include multi-degree-of-freedom motion capabilities to achieve comprehensive coverage of the welding material 2. The welding arm 13 may be equipped with an automated control system to improve the accuracy and consistency of welding.

[0104] The above components are designed to work together to ensure the stability and functionality of the entire system. The support legs 11 provide basic support, the crossbars 12 enhance structural stability, and the gantry 14 provides a mounting platform for the welding arm 13, which performs the welding task.

[0105] The entire mobile frame 1 system allows the welding arm 13 to perform precise welding operations on the welding material 2, while the stability of the frame structure and the flexibility of the welding arm 13 ensure improved welding quality.

[0106] The design of the support legs 11 and the crossbar 12 provides a solid structural support, ensuring the stability of the entire frame during the welding process and preventing the welding arm 13 from shaking or shifting during operation.

[0107] The arrangement of the gantry 14 provides a stable mounting platform for the welding arm 13 , enabling the welding arm 13 to be accurately moved and positioned within the welding area, thereby improving welding accuracy and consistency.

[0108] The flexible design and automated control function of the welding arm 13 can achieve efficient welding operations, reduce the need for manual operation, and improve the efficiency of the overall welding process.

[0109] The structural design of the mobile frame 1 allows the welding arm 13 to move in multiple directions, so that it can adapt to various welding requirements, including complex welding paths and different welding positions.

[0110] The robust frame structure and high-quality welded arm 13 design reduce system wear and maintenance frequency, thereby reducing maintenance difficulty and cost.

[0111] The stable support legs 11 and the sturdy frame design improve safety during operation and reduce operational risks caused by structural instability.

[0112] The integrated design of the mobile frame 1, the gantry 14 and the welding arm 13 makes the entire welding system more compact and efficient, and optimizes the operation and management of the welding process.

[0113] The cooling air assembly 6 is mainly composed of a cooling fan, a cooling pipe, cooling fins and a control system.

[0114] Cooling fans: These are the power source for the cooling components, responsible for generating strong winds. These fans typically feature high-performance motors and optimized blade designs to ensure stable air volume and pressure even during extended operation.

[0115] Cooling ducts are responsible for directing the cool air generated by the cooling fan to the weld area. Guide vanes may be installed inside the ducts to ensure that the cool air is evenly and efficiently directed to the weld. Furthermore, the ducts must be made of heat-resistant materials to prevent deformation or damage in high-temperature environments.

[0116] Cooling fins: Installed at the air outlet of the cooling duct, they further increase the heat dissipation area of ​​the cold air and improve the cooling effect. Cooling fins are usually made of metal materials with high thermal conductivity and can quickly remove heat from the weld area.

[0117] Control system: This controls the cooling fan speed and air flow to meet the cooling requirements under different welding conditions. The control system may include temperature sensors, flow sensors, and automatic regulating valves to achieve precise cooling control.
