[0016] like Figure 1-4 As shown, a bending device for steel structure processing includes a base plate 1, a horizontally arranged hydraulic cylinder 2 is installed on the top of the base plate 1, the free end of the hydraulic cylinder 2 is fixedly connected to the mounting plate 3, and a support mold is installed on the side of the mounting plate 3, and the support mold includes an electromagnetic fixing seat 4, the electromagnetic fixing seat 4 is connected to the mounting plate 3 by bolts, and the side of the electromagnetic fixing seat 4 is connected to the electromagnet 21, and the electromagnet 21 is detachably installed with a punch 6, and the side of the punch 6 facing away from the electromagnet 21 is provided with a groove 7 for placing a steel pipe, and the top of the base plate 1 is also installed with a die mechanism, which includes a die base plate 5, the die base plate 5 is fixedly connected to the top of the base plate 1, and the two corners of the top of the die base plate 5 are fixedly connected with vertically arranged support columns 8, and the top of the support column 8 is fixedly connected with a die top plate 9, and two symmetrically arranged dies 10 are detachably installed between the die base plate 5 and the die top plate 9.

[0017] Specifically, the steel pipe to be bent is placed in the groove three 7 of the punch 6, and the hydraulic cylinder 2 is started. The free end of the hydraulic cylinder 2 moves horizontally to drive the punch 6 to move to the right, that is, to drive the steel pipe to move to the right. During the continuous movement, the two ends of the steel pipe will enter the die 10, providing a support point for the steel pipe, and continue to move, thereby bending the steel pipe. The electromagnet 21 is energized and has magnetism, so that the punch 6 is fixed on the electromagnet 21, which is also convenient for replacing different types of punches 6. The position of the groove three 7 on the punch 6 needs to correspond to the position of the groove one 11 or the groove two 12 of the die 10.

[0018] Groove 11 and groove 2 12 are respectively provided on both sides of the die 10, and the sizes of groove 11 and groove 2 12 are different. A vertically arranged through-hole 13 is provided on the die 10, and the through-hole 13 is located between groove 11 and groove 2 12. Two groups of adjustment holes 14 are provided on the die bottom plate 5 and the die top plate 9, and the two groups of adjustment holes 14 are symmetrically arranged; specifically, different types of grooves 11 and grooves 12 are provided on a die 10 to improve utilization. When using groove 11 or groove 2 12, it is also necessary to replace the appropriate punch.

[0019] A groove 15 is provided on the side of the electromagnet 21 facing away from the electromagnetic fixing seat 4, and a protrusion 16 that cooperates with the groove 15 is provided on the side of the punch 6 close to the electromagnetic fixing seat 4; the longitudinal section of the groove 15 is a dovetail shape; specifically, the punch 6 is installed on the electromagnet 21 through the protrusion 16 and the groove 15, and the dovetail shape increases the connection area.

[0020] The die 10 is fixed between the die bottom plate 5 and the die top plate 9 by a vertically arranged insertion rod 17. The insertion rod 17 passes through the corresponding adjustment hole 14 and the through hole 13 in turn, and the die 10 rotates with the insertion rod 17 as the hinge point; specifically, the die 10 is installed by the insertion rod 17, which is easy to operate and can quickly replace different models of dies 10. When the steel pipe is pushed into the two dies 15, the hydraulic cylinder will continue to move forward. At this time, the two dies 10 rotate with the insertion rod 17 as the support, thereby realizing the bending of the steel pipe.

[0021] A limiting hole 18 is opened on the base plate 1, and the bottom of the mounting plate 3 is connected to a limiting block 19, which moves along the limiting hole 18; specifically, when the free end of the hydraulic cylinder 2 moves, the moving trajectory of the mounting plate 3 is limited by the cooperation between the limiting block 19 at the bottom of the mounting plate 3 and the limiting hole 18.

[0022] An operating ring 20 is fixedly connected to the top of the insertion rod 17; the operating ring 20 is convenient to hold.
