The first electrode conductor 12 applies a force to the junction 4 in various ways, as will be described below.

Example one

When welding is started, the first electrode conductor 12 is driven by the first electrode moving part 11 to be close to the welding position 3 and then reach the welding position 3, at the moment, the first electrode conductor 12 continues to move under the action of the first electrode moving part 11 so as to extrude and apply force to the junction 4, the first electrode conductor 12 is in a power-on state and forms a loop with the junction 4 and the second electrode conductor 22, the junction 4 is heated and is extruded and applied force, and therefore the first rib body 1 and the second rib body 2 are welded at the junction 4; then, the first electrode conductor 12 leaves the welding position 3 under the action of the first electrode moving part 11, and does not contact with the first rib 1 and the second rib 2, the first rib 1 and the second rib 2 move relatively, a next junction 4 is formed on the second electrode conductor 22, the first electrode conductor 12 approaches the welding position 3 again under the action of the first electrode moving part 11, and the above process is continued until the welding is completed.

Example two

When welding is started, the first electrode conductor 12 is driven by the first electrode moving part 11 to be close to the welding position 3, then reaches the welding position 3, and stays at the welding position 3 under the action of the first electrode moving part 11, when the first rib body 1 and the second rib body 2 are intersected at the welding position 3 to form an intersection point 4, the first electrode conductor 12 stays at the welding position 3 and is in contact with the intersection point 4, the first electrode conductor 12 can be enabled to keep at the position but extrude and apply force to the intersection point 4 through the first electrode moving part 11, the first electrode conductor 12 is in an electrified state, and forms a loop with the intersection point 4 and the second electrode conductor 22, the intersection point 4 is heated, heated and extruded and applied force, and therefore the first rib body 1 and the second rib body 2 are welded at the intersection point 4; then, the force applied to the first electrode conductor 12 by the first electrode moving part 11 is cancelled, the first electrode conductor 12 stays at the welding position 3, but only keeps contact with the first rib 1 or the second rib 2, the first rib 1 and the second rib 2 are not forced, and the moving first rib 1 or the moving second rib 2 is prevented from being deformed under the action of force, at the moment, the first electrode conductor 12 is controlled by the control system and is in an unpowered state, and the influence on the first rib 1 and the second rib 2 is smaller; the first rib 1 and the second rib relatively move to form a next junction 4, the first electrode conductor 12 is electrified again, and the force is applied to the junction 4 under the action of the first electrode moving part 11, and the process is continued until the welding is finished. In the process, the first electrode conductor 12 is stationary relative to the welding position 3 and is forced against the junction 4 by means of the first electrode displacement section 11 or another additional means. After welding, the first electrode conductor 12 is separated from the welding position 3 under the action of the first electrode moving part 11, so that the welded reinforcement cage can be conveniently detached from the welding equipment.

The mounting block 221 is of a square structure, and chamfers are arranged on two side edges to prevent the second main rib crossing over the first main rib and the mounting block 221 from colliding with the mounting block 221.

When the welding device is applied to the welding apparatus of this embodiment, the second electrode 20 is disposed on the fixed assembly 40, the second electrode conductor 22 and the second electrode base 24 are correspondingly disposed on the fixed turntable 41 in the circumferential direction and need to rotate along with the fixed turntable 41, the conductive plate 23 and the second electrode moving portion 21 are fixed on the fixed assembly 40, the second electrode conductor 22 and the second electrode base 24 rotate relative to the conductive plate 23, and the conductive plate 23 needs to sequentially contact with the first rib conductor block 222 of each second electrode conductor 22, so that the second electrode conductor 22 is energized at the welding position 3, and therefore, the first rib conductor block 222 has a circumferential friction force on the conductive plate 23, and in order to avoid excessive wear of the first rib conductor block 222 and the conductive plate 23, as shown in fig. 7, the top surface of the first rib conductor block 222 is an arc surface, and the conductive plate 23 is a circular disk, the conductive plate 23 is in point contact or line contact with the top surface of the first rib conductive block 222 by the second electrode moving part 21.

In some embodiments, the first rib body 1 and the second rib body 2 are a main rib and a stirrup in a reinforcement cage, respectively, and during a welding process of the reinforcement cage, the main rib drives the stirrup to rotate, so that the main rib and the stirrup have circumferential impact force and radial impact force on the first electrode conductor 12, and therefore, the stress adjustment portion 13 further includes a circumferential force buffer assembly, and the circumferential force buffer assembly is located between the fixing member 131 and the first electrode moving portion 11; and the stress adjusting part 13 further includes a radial force buffering assembly between the fixing member 131 and the first electrode moving part 11. In other embodiments, the impact force of the first rib 1 and the second rib 2 on the first electrode conductor 12 is only circumferential impact force, and the stress adjustment portion 13 further includes a circumferential force buffer assembly, which is located between the fixing member 131 and the first electrode moving portion 11; in other embodiments, the impact force of the first rib 1 and the second rib 2 on the first electrode conductor 12 is only a radial impact force, and the stress adjustment portion 13 further includes a radial force buffering assembly, and the radial force buffering assembly is located between the fixing member 131 and the first electrode moving portion 11.

Due to the retractility of the elastic member 134, the fixing member 131 can properly move on the sliding rod 133, when the stirrup is uneven, circumferential displacement occurs when the first electrode conductor 12 contacts the junction 4, and the fixing member 131 can properly move along the stress direction, and due to the existence of the elastic member 134, the displacement of the first electrode conductor 12 is limited, so that the first electrode conductor 12 does not deviate from the welding position 3, and hard collision between the first electrode conductor 12 and the junction 4 can be avoided, thereby effectively protecting the first electrode conductor 12. The fixing element 131, the sliding rod 133 and the elastic element 134 are disposed in the receiving groove 132, which can protect these components and also facilitate reducing the volume of the circumferential force buffering assembly, and thus the volume of the whole first electrode 10.
