The implementation principle of the double-gun welding equipment with high automation degree is as follows: when needs weld square pipe and square board, start double-gun welding equipment earlier, then the staff is through operation control panel 9, in order to start first cylinder 5, this first cylinder 5's piston rod drive backup pad 51 removes along fixed orifices 48, make backup pad 51 remove the top of welding hole 11, then place square board in backup pad 51, then utilize fixing bolt 42's head and locating piece 47 to support square board, then place square pipe on fixed plate 4 again, square pipe along locating piece 47 butt on square board.

Then start second cylinder 44, the piston rod drive grip block 45 of second cylinder 44 removes along fixed plate 4, and grip block 45 drives the one end of rubber block 46 butt at square pipe to can be convenient for stabilize the centre gripping with square pipe and square board, then restart first cylinder 5, the piston rod drive backup pad 51 of first cylinder 5 resets, makes backup pad 51 keep away from the bottom of square board.

Then the staff operates control panel 9 again to control two electric welding heads 31 automatic movement to square pipe and square board butt joint department, start two electric welding heads 31, slightly touch the butt joint department of square pipe and square board with welding rod 611 on two electric welding heads 31, can be in order to weld square pipe and square board.

Meanwhile, in the welding process, the traction assembly pulls the welding rod 611 in the winding drum 61 to the conveying cable 63, and then the welding rod 611 is conveyed to the welding head 31 along the conveying cable 63, so that the welding rod 611 can be continuously conveyed to the welding head 31, and the two abutted ends of the square pipe and the square plate can be effectively welded.

After the two ends of the square pipe and the square plate are welded, the square pipe and the square plate are rotated by 90 degrees, and then the other two ends of the square pipe and the other two ends of the square plate are welded according to the steps, so that the square pipe and the square plate can be fastened and welded together, and the process of welding the square pipe and the square plate can be completed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
