Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding head for a straight seam welded pipe machine. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. In the processing of some parts, welding machines are an essential step. The welding head is one of the main working parts of the welding machine, and the energy used in the welding process is ejected from the welding head.

[0003] Please refer to the announcement number CN218193554U for a straight seam welding machine for welded pipes. The machine includes a fixed base, a welding device, and a welding head. The welding device is mounted on the fixed base and located on one side of the fixed base. The welding head is mounted on the welding device and located on one side of the welding device. When straight seam welding of a pipe is required, the pipe is fixed within the fixed component, ensuring the desired straight seam welding position faces upwards. The moving component drives the connecting frame to move along its direction. The movement of the connecting frame drives the movement of the moving block, which in turn drives the movement of the electric push rod. The movement of the electric push rod drives the movement of the crossbeam, which in turn moves the welding head of the welding device on the crossbeam. The electric push rod drives downwards, causing the welding head to contact the pipe. The straight seam welding of the pipe is then achieved by the movement of the moving component, thus avoiding the need for manual pushing of the pipe to achieve straight seam welding and reducing labor costs.

[0004] However, in the patent, during the welding process of the welding machine on the pipe, it is inconvenient to disassemble and replace the welding head, and it is also inconvenient to maintain and care for the welding head, which causes inconvenience to the user and affects the practicality of the welding head of the welding machine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 The welding head of a straight seam welded pipe machine in this embodiment includes a workbench 1, a welding mechanism is provided on the outside of the workbench 1, and a ventilation component is provided on the top of the workbench 1.

[0025] Example 1: The welding mechanism includes a drive adjustment assembly 2 fixedly connected to the workbench 1. The drive adjustment assembly 2 includes a drive device 201, a sliding seat 202, a fixed frame 203, and an electric telescopic rod 204. The sliding seat 202 is threadedly connected to the outside of the drive device 201. The fixed frame 203 is fixedly connected to the top of the sliding seat 202. The electric telescopic rod 204 is fixedly connected to the fixed frame 203. The drive device 201 includes a drive motor and a lead screw. The drive motor is fixedly connected to the workbench 1. The lead screw is fixedly connected to the output end of the drive motor. The sliding seat 202 is threadedly connected to the lead screw. When the drive device 201 is energized, it drives the sliding seat 202 to slide back and forth. The sliding seat 202 drives the fixed frame 203 and the electric telescopic rod 204 to move, which facilitates the welding of pipes.

[0026] The output end of the drive adjustment component 2 is fixedly connected to the welding device 3. The welding device 3 is externally threaded to the welding head body 4. The welding head body 4 has a threaded hole 401 inside. The welding head body 4 is threaded to the welding device 3 through the threaded hole 401, which facilitates the connection between the welding head body 4 and the welding device 3, and makes it easy for the user to disassemble and replace the welding head body 4, as well as for the user to maintain and care for the welding head body 4. The mounting hole is opened inside the fixing frame 203. The electric telescopic rod 204 is fixedly connected to the fixing frame 203 through the mounting hole, which facilitates the connection between the electric telescopic rod 204 and the fixing frame 203. The output end of the welding device 3 is fixedly connected to the electric telescopic rod 204. When the electric telescopic rod 204 is energized, it extends and retracts, driving the welding device 3 and the welding head body 4 to move up and down, thereby adjusting the height of the welding device 3 and the welding head body 4.

[0027] In addition, a conductive seat 5 is fixedly connected inside the welding head body 4. A tungsten electrode 402 that is inserted into the conductive seat 5 is inserted into the welding head body 4. A fixing rod 6 is fixedly connected inside the conductive seat 5. A telescopic spring 7 is sleeved on the outside of the fixing rod 6. An adjusting block 8 is sleeved on the outside of the fixing rod 6. A push rod 9 that passes through the conductive seat 5 and the welding head body 4 is fixedly connected to the back of the adjusting block 8. Adjusting rods 10 are hinged on both the left and right sides of the adjusting block 8. Through slots are opened inside the welding head body 4 of the conductive seat 5. The push rod 9 passes through the conductive seat 5 and the welding head body 4 through the through slots, making it convenient for the user to push the push rod 9 downward, causing the adjusting block 8 to move downward, causing the telescopic spring 7 to retract, and causing the two adjusting rods 10 to move downward.

[0028] Secondly, the other end of the adjusting rod 10 is hinged to a limiting block 11 that engages with the tungsten electrode 402. A slider 12 is fixedly connected to the bottom of the limiting block 11, and the slider 12 is slidably connected to the conductive base 5 to limit the movement of the limiting block 11, facilitating its sliding and allowing the user to easily disassemble and maintain the welding head body 4. The tungsten electrode 402 has two limiting holes inside, through which the limiting block 11 engages with the tungsten electrode 402, thus limiting and fixing the tungsten electrode 402. When the two adjusting rods 10 move downwards, they cause the two limiting blocks 11 to slide apart, separating the limiting blocks 11 from the tungsten electrode 402 and releasing the limitation on the tungsten electrode 402, making it convenient for the user to remove the tungsten electrode 402 for replacement or inspection.

[0029] It should be noted that by setting up a welding mechanism, the adjustment and use of the welding machine are facilitated, and the welding head can be easily disassembled and replaced by the user. This also facilitates the maintenance and upkeep of the welding head, solving the problem that it is inconvenient to disassemble and replace the welding head or to maintain and upkeep it during the welding process of pipes, which causes inconvenience to the user and affects the practicality of the welding head.

[0030] Specifically, during the welding process of pipes using the welding machine, the user can unscrew the welding head body 4 to disconnect the threaded connection between the welding head body 4 and the welding device 3, allowing for the disassembly and replacement of the welding head body 4. The user can also push the push rod 9 downwards, causing the adjusting block 8 to move downwards, which in turn causes the telescopic spring 7 to contract, moving the two adjusting rods 10 downwards. This causes the two limiting blocks 11 to slide apart, separating the limiting blocks 11 from the tungsten electrode 402, releasing the limiting effect on the tungsten electrode 402, and allowing the tungsten electrode 402 to be removed for replacement or inspection. This facilitates the user's disassembly, replacement, and maintenance of the welding head, making the use of the welding machine easier.

[0031] Example 2: Please refer to Figures 2 to 4 The ventilation assembly includes an air inlet pipe 13 fixedly connected to the welding head body 4, a sealing ring 14 fixedly connected to the outside of the conductive base 5 and fitting against the welding head body 4, an air outlet 15 opened at the bottom of the welding head body 4, and the other end of the air inlet pipe 13 fixedly connected to the gas supply assembly. Argon gas enters the interior of the welding head body 4 through the air inlet pipe 13 and is discharged through the air outlet 15, forming a protective layer around the arc welding to isolate the air and ensure high-quality welding as much as possible.

[0032] It should be noted that by setting up a ventilation component, the welding quality of the welding machine is improved, which facilitates the welding process of pipes.

[0033] Specifically, during the welding process of the pipe using the welding machine, argon gas enters the interior of the welding head body 4 through the gas inlet pipe 13 and is discharged through the gas outlet 15, forming a protective layer around the arc welding to isolate the air and ensure high-quality welding as much as possible.

[0034] The working principle of the above embodiments is as follows:

[0035] (1) During the welding process of the straight seam welded pipe machine, the user can twist the welding head body 4 to separate the threaded connection between the welding head body 4 and the welding device 3, disassemble and replace the welding head body 4, and push the push rod 9 downward to move the adjusting block 8 downward, causing the telescopic spring 7 to contract and the two adjusting rods 10 to move downward, causing the two limit blocks 11 to slide apart, separating the limit block 11 from the tungsten electrode 402, releasing the limit on the tungsten electrode 402, and removing the tungsten electrode 402 for replacement or inspection. This achieves the purpose of facilitating the user's disassembly, replacement and maintenance of the welding head, and making it easier for the user to use the welding machine.

[0036] (2) During the welding process of the straight seam welded pipe machine, argon gas enters the interior of the welding head body 4 through the air inlet pipe 13 and is discharged through the air outlet 15, forming a protective layer around the arc welding to isolate the air and ensure high-quality welding as much as possible.
