When the steel arch production line is processed, the steel arch semi-finished product on the semi-finished product storage rack 800 is transferred to the input line 110, the steel arch semi-finished product on the input line 110 is transferred to the output line 120 after welding is completed, and the steel arch finished product is transferred to the steel arch finished product storage rack 900 through the output line 120. In some embodiments, the conveyor line 100 is a chain conveyor line that advances the i-steel section bar under the drive of a motor. In some embodiments, the blank storage rack 800 may be provided with an automatic feeding mechanism.

The welding manipulators 500 are arranged on two sides of the conveying line 100 and are used for welding the I-shaped steel profiles clamped by the clamping conversion assembly 400 at the first angle position and the second angle position. In the present embodiment, the clamping switch assembly 400 is positioned where the input line 110 transitions to the output line 120. The to-be-welded i-shaped steel section on the input line 110 moves into the clamping conversion assembly 400 along with the input line 110, and is clamped by the clamping conversion assembly 400, at this time, the to-be-welded i-shaped steel section is located at a first angle position, and the welding manipulator 500 performs first welding on the i-shaped steel section. After welding, the clamping conversion assembly 400 turns the i-steel section from the first angle position to the second angle position, and the welding manipulator 500 performs second welding on the i-steel section. The h-section after the second welding is finished is a finished steel arch, and at this time, the clamping conversion assembly 400 loosens the h-section, and the h-section can enter the output line 120.

At the moment, two ends of the I-shaped steel section are just positioned on the spot welding stations 700 at two sides, and after the left and right positions of the I-shaped steel section are manually adjusted, the end plates are spot-welded. When the second driving element 320 drives the lifting bracket 310 to move downwards, the i-steel profile is lowered onto the input line 110.

A plurality of lift assemblies 300 may be disposed laterally along the input line 110, and the plurality of lift assemblies 300 may be simultaneously actuated to collectively lift the same i-section steel section.
Further, after the spot welding of the i-shaped steel section is completed, the second driving element 320 drives the lifting bracket 310 to move downwards, the first driving element 220 drives the rotating member 210 to rotate downwards, and the blocking portion 211 removes the blocking of the i-shaped steel section. At this point, the i-section can continue to advance for full welding at the welding robot 500.
