The first unloading stem 3 is the same size as the second unloading stem 7. A bracket is fixedly connected to the upper end of the workbench 1, and the cylinder guide sleeve 2 is fixedly connected through the upper end bracket of the workbench 1. The cylinder guide sleeve 2 is at the upper end of the lower mold assembly 22, which is convenient for moving the cylinder guide sleeve 2 through the oil pump motor group 9, thereby realizing the I-shaped The effect of steel punching, the shape of the movable frame 10 is "mouth" shaped, the number of arc grooves 23 is two, the curvature of the arc groove 23 is opened, the number of fixing bolts 24 is two, the fixing bolts 24 are movable inside the arc groove 23, the movable frame 10 is the same shape as the mounting frame 21, and the angle of the movable frame 10 is adjusted according to the state of the I-beam, the number of limiting telescopic rods 12 is two, and the upper end of the limiting telescopic rod 12 is fixedly connected to one side of the upper end of the movable frame 10, the number of the mounting block 14 and the tugboat 19 is two, the folding plate 16 and the outer side of the slope card block 17 slide on the inner side of the sliding card hole 20, the number of the sliding card hole 20 is opened in two groups, the lower end of the movable plate 13 is provided with a sliding card hole 20, the shape of the sliding card hole 20 is a rectangular body, and a rectangular body card groove is opened on one side of the middle end of the sliding card hole 20, the outer side of the folding plate 16 is slidably connected to the inner side of the mounting block 14, so as to fix the I-beam with different tugboats 19 according to the size of the I-beam to prevent the punching from being misplaced during punching.

[0026] Working process: When the device is in use, the external power supply is powered on. When the I-beam needs to be positioned, the I-beam is placed on the upper part of the tugboat 19 at the lower end, and the electric cylinder 11 fixedly connected to the lower end of the movable frame 10 is started. The lower end of the electric cylinder 11 moves to drive the movable plate 13 fixedly connected to the lower end to move. The movement of the movable plate 13 drives the limit telescopic rod 12 fixedly connected to the upper end to extend. The upper end of the limit telescopic rod 12 is fixedly connected to one side of the upper end of the movable frame 10. The limit telescopic rod 12 plays a role in limiting the movement of the movable plate 13. The movable plate 13 moves to drive the mounting block 14 arranged at the lower end to move, and the mounting block 14 moves to drive the tug 19 arranged at the lower end to move. When the tug 19 of the upper part is close to the I-beam, the tug 19 can clamp the I-beam.

The effect is to improve the stability of the I-beam punching and avoid the misalignment when placing the punching. After the punching is completed, the I-beam is unloaded through the first unloading stem 3 and the second unloading stem 7. When the I-beams of different sizes and widths need to be positioned by the tugboat 19, the folding plate 16 is pressed, and the movement of the folding plate 16 drives the slope block 17 fixedly connected on one side to move. The movement of the folding plate 16 drives the spring 18 to deform, and the spring 18 plays the effect of resetting the folding plate 16. When the slope block 17 moves, the slope block 17 is away from the sliding card hole 20 The groove is set on the inner side. At this time, the slope block 17 slides inside the fixed hollow shell 15, and the mounting block 14 is directly moved. After the fixed hollow shell 15 fixedly connected to one side of the mounting block 14 is away from the sliding card hole 20, the mounting block 14 and the tugboat 19 can be replaced. With the same operation as above, the upper mounting block 14 is moved out of the side of the movable plate 13. The arc groove 23 opened on the inner side of the lower end of the movable frame 10 facilitates the fixing bolt 24 to be fixed to the inner side of the upper end of the workbench 1, and at the same time facilitates the angle adjustment of the movable frame 10.
