Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a flange welding device for flange production. Background Art

[0002] Flange is an important pipeline fitting for connecting pipes, valves, pumps and other equipment. Flange is a form of flange, usually a flat disc-shaped structure with holes similar to flanges for bolts to pass through. Flanges are usually used to connect pipes or equipment in pipeline systems. Adjacent flanges are firmly fixed together by bolts to form a tight pipeline connection. In some industrial applications, flanges are connected to pipes or equipment by welding to ensure the strength and sealing of the connection.

[0003] After searching the Chinese patent document with the announcement number CN215824646U, it is found that a flange welding device for flange pipe production is involved, including an operating table, a clamping structure is arranged on the top of the operating table, a fixing structure is arranged on the top of the operating table, and the inside of the clamping structure includes two fixing plates, and the opposite sides of the two fixing plates are movably installed with a mounting screw with one end penetrating and extending to the opposite side thereof, and the outer surfaces of the two mounting screws are movably installed with mounting sleeve rods, and the tops of the two mounting sleeve rods are fixedly installed with a first mounting buckle, and the opposite sides of the two fixing plates are fixedly installed with a second mounting buckle, and the bottoms of the two second mounting buckles are respectively movably installed with telescopic rods between the tops of the two first mounting buckles. The flange welding device for flange pipe production can change the size of the clamping range by providing a clamping structure, thereby facilitating the clamping of pipes of different sizes.

[0004] However, in this patent, although flanges of different sizes can be welded, when welding two flanges or welding a flange to a pipe together, both cannot be stable. During welding, it is easy to cause slight shaking and misalignment, thereby affecting the welding accuracy and bringing a bad experience. When welding the flange, the device needs to manually rotate the pipe and the flange to achieve all-round welding of the flange, which reduces the welding quality of the flange and the pipe.

The fifth cylinder 6028 is turned on to drive the push-pull plate 6029 to move in the opposite direction. The vertical rods 6024 on both sides of the lifting plate 6021 will be driven to move along the guide rods 6031 toward the middle of the lifting plate 6021, thereby loosening the pipe 9 and the welded flange 11, and the welded flange 11 will be placed on the unloading conveying mechanism 5, and the welded flange 11 will be transported out under the action of the unloading conveying mechanism 5, and the fourth cylinder 6019 will be turned on to drive the lifting plate 6021 to move upward, and the clamping rod 6023 on the clamping member 605 on the lifting plate 6021 will be pulled out from the inside of the pipe 9, and then, the third motor 6016 will be turned on to drive the rotating arm 6017 to rotate again, driving the lifting member 604 and the clamping member 605 to reset; The first cylinder 202 is turned on to drive the lifting plate 201 to move upward, and the lifting plate 201 moves upward until the positioning member 206 is inserted into the through hole 303 on the workbench 3, until the bottom of the push rod 2014 is located above the bottom of the flange 11, and the bottom of the push rod 2014 is not higher than the top of the flange 11, and the second motor 2012 is turned on to drive the first threaded rod 2013 to rotate, and the rotation of the first threaded rod 2013 drives the first sliding sleeve 2015 and the second sliding sleeve 2018 to move in the opposite direction of the first threaded rod 2013, and the first sliding sleeve 2015 When the second sliding sleeve 2018 moves, it will drive one end of the first support rod 2016 and the second support rod 2017 to move with the first sliding sleeve 2015 and the second sliding sleeve 2018, and the other end of the first support rod 2016 and the second support rod 2017 will push the push rod 2014 outward until the push rod 2014 contacts the inner ring wall of the pipeline 9 and the flange 11, so as to achieve the purpose of fixing the flange 11 and the pipeline 9 from the inside. After the flange 11 and the pipeline 9 are fixed, the welding mechanism 10 welds the connection between the flange 11 and the pipeline 9; After the welding of the flange 11 and one side of the pipe 9 is completed, the third cylinder 701 drives the first rack 703 to move, and the first rack 703 and the second rack 707 are both meshed with the gear 702.
