A manufacturing and processing device for metal pipes

Abstract

The present invention discloses a manufacturing and processing device for metal pipes, which relates to the technical field of metal pipe welding. The device includes an installation mechanism and further includes: an inclined upward gas supply mechanism, which is installed on the installation mechanism and is used to supply gas obliquely upward to the inner wall of the top of the metal pipe during the welding of the metal pipe, so that argon gas rises along the inner wall of the top of the metal pipe and contacts the welding point. By installing the inclined upward gas supply mechanism in the present invention, a small amount of argon gas is ejected, so that the argon gas flows along the inner wall of the top of the metal pipe directly to contact the welding point. During the contact process, the argon gas is consumed, and there is no need to eject a large amount of argon gas for centralized use. The ejected gas directly contacts the welding point, which can reduce the consumption of argon gas and save the cost of argon gas. By installing the rotating material supporting mechanism, the metal pipe rotates and tilts. Due to the principle that the density of argon gas is greater than that of air, the amount of argon gas discharged from one end of the metal pipe is reduced, and the pressure sinks inside the metal pipe for reuse, improving the utilization rate of argon gas and reducing the cost of argon gas.

Description

Technical Field

[0001] The present invention relates to the technical field of metal pipe welding, and particularly relates to a manufacturing and processing device for metal pipes. Background Art

[0002] For stainless steel welding and processing, two stainless steel pipes with the same diameter are welded together to reach a specified length for use. During stainless steel welding, argon gas needs to be continuously added to avoid oxidation and affect the welding quality.

[0003] In the prior art, during preliminary welding, sufficient argon gas needs to be added into the metal pipe, and then the argon gas is used in contact with the welding position during welding to achieve welding protection. However, because too much argon gas is filled, a large amount of residue will appear inside the metal pipe after welding, resulting in waste of argon gas. Since one end of the metal pipe is closed and the other end is open when the argon gas is supplied, as the gas is continuously filled, the unused gas will escape from the other end, resulting in waste of argon gas.

[0036] It further includes:

[0037] An inclined upward air supply mechanism 2, which is installed on the installation mechanism 1 and is used to supply air obliquely upward to the inner wall of the top of the metal pipe during the welding of the metal pipe, so that argon gas rises along the inner wall of the top of the metal pipe and contacts the welding point;

[0038] The inclined upward air supply mechanism 2 includes an installation frame 21 fixed on the top of the base 11. A first guide rod 22 is fixed inside the installation frame 21.

[0051] The second driving mechanism 7 includes a second motor 71 fixed on one side of the bracket 52. At one end of the output shaft of the second motor 71, a second gear 72 is fixed. The second gear 72 meshes with the third one-way gear 57 and meshes with the fourth one-way gear 63. The second motor 71 is electrically connected to the controller 8.

[0052] The welding mechanism 9 is installed on the clamping mechanism 6 and is used to weld the metal pipe;

[0053] The welding mechanism 9 includes a hinged frame 91 fixed on one side of the moving frame 64. At the bottom of the hinged frame 91, a welding torch 92 is rotatably connected. The welding torch 92 is electrically connected to the controller 8.

[0054] A controller 8, which is installed on the installation mechanism 1 and is electrically connected to the first driving mechanism 4, the second driving mechanism 7, the obliquely upward air supply mechanism 2 and the welding mechanism 9.

[0055] Working principle:

[0056] First, place two metal pipes on the first limit frame 58 respectively, with the welding ends facing each other and in contact with the butt limit plate 66. Then, start the second motor 71 through the controller 8 to drive the second gear 72 to reverse. The reverse rotation of the second gear 72 meets the rotation direction for the fourth one-way gear 63 to drive the second reciprocating screw 62 to rotate. The rotation of the second reciprocating screw 62 causes the moving frame 64 to drive the second limit frame 65, the butt limit plate 66, and the welding mechanism 9 to move downward. The downward movement of the butt limit plate 66 makes the two metal pipes face each other, and the welder 92 contacts the tops of the two metal pipes. Then, the second limit frame 65 and the first limit frame 58 clamp the metal pipes.

[0057] Start the second motor 71 to rotate forward. The forward rotation of the second motor 71 meets the rotation direction for the third one-way gear 57 to drive the second rotating shaft 55 to rotate. The third one-way gear 57 drives the second rotating shaft 55 and the second bevel gear 56 to rotate. The rotation of the second bevel gear 56 revolves around the first bevel gear 53, so that the second driving mechanism 7, the clamping mechanism 6, the welding mechanism 9, the metal pipes and part of the rotating material supporting mechanism 5 rotate. After rotating a specified angle, stop rotating. At this time, one side of the metal pipe contacts the rubber column 32, and one end is opposite to the obliquely upward air supply mechanism 2. Then, turn off the second motor 71.

[0058] The starting motor 1 drives the first gear 42 to rotate forward, meeting the rotation direction of the first one-way gear 24 to drive the first reciprocating screw 23, so that the moving plate 25 pushes the sealing block 26 and the electric gas supply nozzle 27 to move, inserting the electric gas supply nozzle 27 into the interior of the metal tube, and the sealing block 26 blocks one end of the metal tube. Then, the electric gas supply nozzle 27 is turned on, and the argon gas supply device supplies argon gas into the interior of the metal tube through the electric gas supply nozzle 27. The inclined electric gas supply nozzle 27 blows the gas towards the top inner wall of the metal tube. Since the metal tube is inclined at this time, the filled gas will first contact the position where the welding torch 92 contacts the metal tube. Then, because the density of argon is higher than that of air, when there is no gas thrust ejected from the electric gas supply nozzle 27, it will sink down along the inclined metal tube, reducing the amount of argon exhausted from the other end and improving the utilization rate of argon during welding. While supplying gas, the starting motor 1 drives the first gear 42 to rotate in reverse. The reverse rotation of the first gear 42 meets the rotation direction of the second one-way gear 33 to drive the first rotating shaft 31, so the first rotating shaft 31 rotates and drives the metal tube to rotate through the rubber column 32. Since the rotation direction of the wheel is the same as that of the metal tube, the metal tube can rotate during clamping. During the rotation process, the welding torch 92 welds the weld seam. After rotating one circle, the welding is completed. Then, the starting motor 1 drives the first gear 42 to rotate forward, causing the moving plate 25 that has moved to the end of the wire to drive the sealing block 26 and the electric gas supply nozzle 27 to return to their original positions. Then, the second motor 71 rotates forward, causing the metal tube to continue rotating. After rotating a specified angle, the second motor 71 drives the second gear 72 to rotate in reverse, causing the moving frame 64 to move upward, releasing the clamping of the metal tube. The metal tube slides downward obliquely due to its own gravity to the material sliding rack 13, completing the blanking, and continues to rotate to return to its original position.

[0059] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
