Embodiment Construction

[0026] Combine below Figure 1 to Figure 6 , the present invention is further described:

[0027] Such as figure 1 As shown, an automatic submerged arc welding machine, the submerged arc welding machine 2 is installed on the welding tracker 3, the boiler body 1 is set on the furnace body rotary tooling 5 for rotating motion, the U-shaped head of the boiler body 1 and the tube plate The joint is the weld seam that needs to be welded. The welding tracker 3 expands and contracts axially with the deformed tube sheet 11. This axis is also the rotation axis 6 of the furnace body, and the submerged arc welding machine 2 also performs telescopic movement correspondingly to ensure that the welding torch always follows the welding. The seam 14 is gone, thus ensuring the welding quality and welding efficiency.

[0028] Furnace body rotating tooling 5 includes installation platform, passive pulley group 51, roller group 51 and motor 53, motor 53 drives roller group 51 to rotate, roller ...

Abstract

The invention relates to an automatic submerged arc welding machine, which comprises a welding tracker (3), a welding wire (21) and a gun head (22), wherein an automatic submerged arc welding machine (2) is fixedly arranged on a tracker moving part (32), a boiler body (1) is arranged on a boiler body rotating tooling (5), a connecting part of a U-shaped seal head (13) of the boiler body (1) and a pipe plate (11) is a welding bead (14) to be welded, the welding tracker (3) extends and retracts in the axial direction of the deformed pipe plate (11), and in addition, the submerged arc welding machine (2) also does corresponding extension and retraction movement so that a welding gun always walks along with the welding bead (14). The automatic submerged arc welding machine has the advantages that because the submerged arc welding machine moves along with the tracker moving part through the pushing force of a pressure spring, in addition, a tracking bearing of the tracker does extension and retraction movement close to the pipe plate, the welding gun is enabled to realize the welding without leaving the welding bead, and the welding quality and the welding efficiency are ensured.

Description

technical field [0001] The invention relates to a submerged arc welding machine, in particular to an automatic submerged arc welding machine. Background technique [0002] Submerged arc welding machine consists of welding power supply, submerged arc welding machine and auxiliary equipment. Its power supply can use AC, DC or both AC and DC. Submerged arc welding machines are divided into two categories: automatic welding machines and semi-automatic welding machines. Automatic submerged arc welding machine is composed of submerged arc welding machine and auxiliary equipment, which can achieve automatic welding. The main functions of automatic submerged arc welding machine are: 1. Continuously feed welding wire to the welding area; 2. Transmission welding current; 3. 1. Make the arc move along the seam; 4. Control the main parameters of the arc; 5. Control the start and stop of welding; 6. Spread flux to the welding area; 7. Adjust the position of the welding wire end before...
