[0032] When in use, when it is necessary to weld two groups of angle steel bodies 5 to extend the overall length, the angle steel body 5 is placed between the moving wheel 65 and the guide wheel 68, the first electric push rod 66 is turned on to drive the lifting plate 67 to move upward, the lifting plate 67 moves upward to drive the guide wheel 68 to move upward, and the guide wheel 68 cooperates with the moving wheel 65 to clamp the angle steel body 5 in the up and down directions, and the second electric push rod 611 is turned on to drive the moving block 612 to move to the front end, and the moving block 612 moves to the front end to drive the clamping wheel 613 to the front end to cooperate with the auxiliary wheel 610 to clamp the angle steel body 5 in the front and back directions, and then the motor 63 can be turned on. The motor 63 drives the rotating shaft 64 to rotate through its output shaft, and the rotating shaft 64 drives the moving wheel 65 to rotate. The rotating wheel 65 drives the angle steel body 5 to move through the friction force, so that the two groups of angle steel bodies 5 can be driven to dock, so as to facilitate welding, and the movement is relatively stable and will not cause the displacement of the rear end head sinking. Before the two groups of angle steel bodies 5 are combined, they can be moved to a suitable position, and then the hydraulic cylinder 61 is turned on to drive the lifting seat 62 to move upward, and the lifting seat 62 moves upward to drive the rotating shaft 64 to move upward, and the moving wheel 65 leaves the angle steel body 5. The upward movement of the rotating shaft 64 will make the driving gear 71 and the driven gear 71 move upward. The gear 74 is meshed, and the starting motor 63 drives the rotating shaft 64 to rotate. The rotation of the rotating shaft 64 drives the driving gear 71 to rotate. The rotation of the driving gear 71 drives the driven gear 74 to rotate.

At the beginning, the rotating gear 75 rotates and its upper teeth mesh with the teeth on the gear rod 711, which will drive the gear rod 711 to move toward the air pressure chamber 77. The movement of the gear rod 711 toward the air pressure chamber 77 will drive the pressure plate 79 and the first piston rod 78 to move toward the air pressure chamber 77. The return spring 710 is compressed, and the first piston rod 78 moves toward the air pressure chamber 77. The movement in the 7-direction will cause the second piston rod 712 to move downward through the air pressure in the air pressure chamber 77. The downward movement of the second piston rod 712 drives the file 713 to move downward. When the rotating gear 75 rotates to the point where the toothless part is disengaged from the toothed rod 711, the return spring 710 rebounds and drives the pressure plate 79, the first piston rod 78 and the toothed rod 711 to move in the opposite direction to restore. At this time, the air pressure in the air pressure chamber 77 drives the second piston rod 712 and the file 713 to move upward to restore, thereby forming a cycle. The file 713 repeatedly moves downward to file the side end of the angle steel body 5 to prevent excessive surface oxides from affecting subsequent spot welding.

[0033] See also Figure 1-10On the basis of the above embodiment, in another embodiment of the present invention, the waste collecting mechanism 8 includes a connecting groove 81, the connecting groove 81 is opened at the top of the base 1, and a slide groove 82 is opened at the rear end of the connecting groove 81. A closing plate 83 is slidably connected inside the slide groove 82. The end of the closing plate 83 away from the slide groove 82 is initially located near the top of the connecting groove 81. The closing plate 83 will close the position of the connecting groove 81 near the top in the initial state to prevent objects from falling into the connecting groove 81, and at the same time, it is convenient for the electric welder to stand. A storage groove 84 is provided at the bottom, and a collection box 85 is arranged inside the storage groove 84. A hydraulic bin 86 is penetrated and fixedly connected to the rear end of the slide groove 82. A third piston rod 87 is slidably connected to the internal piston of one end of the hydraulic bin 86. A connecting plate 88 is fixedly connected to the top of the third piston rod 87. The end of the connecting plate 88 away from the third piston rod 87 is fixedly connected to the lifting seat 62. A fourth piston rod 89 is slidably connected to the internal piston of the other end of the hydraulic bin 86. The end of the fourth piston rod 89 away from the hydraulic bin 86 is fixedly connected to the rear end of the closing plate 83. An automatic pop-up assembly 9 is provided inside the collection box 85, and the automatic pop-up assembly 9 includes a pop-up spring 91, a slide post 92, a slot 97 and a groove 98. The pop-up spring 91 is fixedly connected to the inner wall of the storage slot 84, the top of the slide post 92 is fixedly connected to the inner bottom of the storage slot 84, the surface of the slide post 92 is slidably connected to a load-bearing plate 93, the surface of the slide post 92 is sleeved with a compression spring 94, the bottom of the load-bearing plate 93 is fixedly connected to a pressure rod 95, the side of the pressure rod 95 is fixedly connected to a limiting plate 96, and the slot 97 is opened at the bottom of the collection box 85. The groove 98 is opened at the inner bottom of the storage slot 84, and a telescopic spring 99 is arranged inside the groove 98. The inner part of the groove 98 is slidably connected with an arc block 910 through the telescopic spring 99. The end of the pressure rod 95 away from the load-bearing plate 93 penetrates and is slidably connected to the top of the slot 97. In the initial state, one third of the arc block 910 is located in the slot 97. When the pressure rod 95 moves downward, the arc block 910 can be pressed down to make the arc block 910 leave the slot 97, and the arc block 910 is stuck in the slot 97 so that the collection box 85 cannot leave the storage slot 84.

[0034] When in use, when the hydraulic cylinder 61 is turned on to drive the lifting seat 62 to move upward, the lifting seat 62 moves upward and also drives the connecting plate 88 to move upward. The connecting plate 88 moves upward and drives the third piston rod 87 to move upward. The third piston rod 87 moves upward and drives the fourth piston rod 89 to move toward the rear end through the hydraulic pressure in the hydraulic chamber 86. The fourth piston rod 89 moves toward the rear end and drives the closing plate 83 to leave the connecting groove 81. At this time, the waste generated when filing the side end of the diagonal steel body 5 will fall into the collecting box 85 through the connecting groove 81 for centralized collection. When the hydraulic cylinder 61 is turned on to drive the lifting seat 62 to move downward and restore, the connecting plate 88 moves downward and drives the third piston rod 87 to move downward and restore. At this time, the hydraulic pressure in the hydraulic chamber 86 drives the fourth piston rod 89 and the closing plate 83 to move toward the front end and restore. The closing plate 83 closes the connecting groove 81 again to prevent foreign matter from entering and passing through. The welder is standing, and when more waste is lifted or lowered into the collection box 85, the waste is accumulated on the load-bearing plate 93, and its gravity will press down the load-bearing plate 93, and the compression spring 94 will be compressed. The downward movement of the load-bearing plate 93 will drive the pressure rod 95 to move downward, and the downward movement of the pressure rod 95 will squeeze the arc block 910 to make it leave the slot 97. The limiting plate 96 can limit the downward movement distance of the pressure rod 95 to prevent the pressure rod 95 from moving excessively. When the arc block 910 leaves the slot 97, the pop-up spring 91 rebounds and drives the collection box 85 to pop out of the storage slot 84, thereby reminding the staff to clean it up. When the collection box 85 is reinstalled, the collection box 85 squeezes the pop-up spring 91 again, and at the beginning the arc surface of the arc block 910 will be squeezed and retracted into the groove 98. When the slot 97 is fitted with the groove 98, the telescopic spring 99 rebounds and drives the arc block 910 to be stuck in the slot 97 to limit the collection box 85.
