Description

Technical Field

[0001] The utility model relates to the technical field of round pipe welding, in particular to welding equipment for round pipe processing. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. When welding round tubes, welding equipment uses the energy of a laser beam to melt the surface of the material. The laser beam is focused into a very small point through a lens or a reflector, allowing the laser beam to concentrate energy in a very short time, so that the temperature of the welding part of the round tube rises above the melting point, producing a molten state, and then cools and solidifies to form a weld, thereby forming the welding work of the round tube.

[0003] When existing welding equipment welds round pipes, a large amount of heat may be generated at the welding points and welding joints of the round pipes due to the effects of welding current and high temperature. If the heat is too high, thermal deformation may occur at the welding points and welding joints of the round pipes, which will not only affect the welding quality of the round pipes, but also cause thermal damage to the welding joints, thereby reducing their service life. For example, a new type of water conservancy pipeline welding equipment disclosed in application number CN202223572615.0 does not have a water cooling structure, which makes it difficult to dissipate the high temperature generated during the welding of the pipelines. In a high temperature environment, metals are easily oxidized to generate oxides, thereby affecting the welding effect and material properties of the pipelines.

[0004] Therefore, it is necessary to invent a kind of round tube processing welding equipment to solve the above problems. Summary of the invention

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual Figure 1-3 When using the device, first place the welding equipment stably in a suitable position, then place the two round tubes to be welded on the two No. 1 positioning seats 18 respectively, and start the driving motor 8 through the controller, and drive the bidirectional screw 9 to rotate through the driving motor 8, so that the No. 1 sliding seat 10 and the No. 2 sliding seat 12 are slidably adjusted under the action of the guide rod 11 and the bidirectional screw 9, so that the two lower clamps 14 and the upper clamps 16 can be adjusted according to the length of the round tube, and then the upper clamps are pulled upward according to the outer diameter of the round tube. 16, when the round tube passes through the lower clamping plate 14 and the upper clamping plate 16, the upper clamping plate 16 can be released, so that the lower clamping plate 14 and the upper clamping plate 16 clamp and fix the round tube.

Finally, the welding mechanism 5 and the welding head 6 are used to weld the welding points of the two round tubes.

[0030] Refer to the instruction manual Figure 4-5 When using the device, the water pump 23 is started while the welding head 6 is welding the round pipe. The cold water in the water tank 22 can be introduced into the nozzle 25 through the water pipe 24 by the water pump 23.

Later, it is only necessary to pull out the water collecting box 27 to treat the wastewater.
