[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] In this technical solution, a steel pipe bending device includes a bottom plate 1. One side of the upper end of the bottom plate 1 is provided with a support frame 2, and a storage rack 3 is installed at the upper end of the support frame 2. On the other side of the upper end of the bottom plate 1, there is a turning and bending structure. The turning and bending structure includes two bearing racks 4, two driving members 5, two first connecting shafts 6, two rotating plates 7, two adjusting grooves 8, two adjusting components, and two installation and operation components;

[0028] Two bearing brackets 4 are respectively installed on both sides of the upper end of the bottom plate 1. Two driving members 5 are respectively installed in the two bearing brackets 4. Two first connecting shafts 6 are respectively movably inserted into the two bearing brackets 4 and are respectively connected to the driving ends of the two driving members 5. One ends of the two rotating plates 7 are respectively fixedly connected to the two first connecting shafts 6. Two adjusting grooves 8 are respectively opened at the upper ends of the two rotating plates 7. Two adjusting components are respectively inserted into the two adjusting grooves 8. Both ends of the two installation operation components are respectively connected to the two first connecting shafts 6 and the two adjusting components.

[0029] In this technical solution, when bending a steel pipe, the staff first powers on the device, and then, according to steel pipes of different specifications, installs the two installation operation components between the two first connecting shafts 6 and the two adjusting components respectively. Then, according to the specifications of the steel pipe, by operating the adjusting components in the adjusting grooves 8, the distance between the two installation operation components is changed. Then, the steel pipe is placed on the upper ends of the support frame 2 and the storage rack 3. The steel pipe is stored through the three storage grooves 21 at the upper end of the storage rack 3. Then, the pressing structure is driven to press and fix the steel pipe. Then, the two driving members 5 at the upper ends of the two bearing brackets 4 are driven. The two first connecting shafts 6 are driven to rotate by the two driving members 5, so that the two rotating plates 7 rotate following the two first connecting shafts 6. The installation operation components located at the upper ends of the two adjusting components rotate around the installation operation component between the two first connecting shafts 6 to perform a bending operation on one end of the steel pipe.

[0030] In some technical solutions, refer to Figure 1 , both of the two adjusting components include a lead screw 9, a moving block 10 and a second connecting shaft 11;

[0031] The lead screw 9 is movably inserted into the adjusting groove 8. The moving block 10 is movably inserted into the adjusting groove 8 and is movably sleeved on the upper end of the lead screw 9. One end of the second connecting shaft 11 is movably connected to one side of the moving block 10.

[0032] In this technical solution, when adjusting the distance between the two installation operation components, the lead screw 9 in the adjusting groove 8 is turned. Under the cooperation of the internal thread opened between the lead screw 9 and the moving block 10, the moving block 10 moves in the adjusting groove 8 to change the position of the second connecting shaft 11, and thus the adjustment of the distance between the two installation operation components can be realized.

[0033] In some technical solutions, refer to Figure 1 , one of the installation operation components includes two installation grooves 12, an operation shaft 13, two connecting blocks 14, two positioning screws 15 and three operation rollers 16;

[0034] Two mounting grooves 12 are respectively formed on one side of two first connecting shafts 6. The operating shaft 13 is located between the two first connecting shafts 6. Two connecting blocks 14 are respectively installed on both sides of the two operating shafts 13 and are respectively movably embedded in the two mounting grooves 12. Two positioning screws 15 are respectively embedded in the two first connecting shafts 6 and the two connecting blocks 14. Three operating rollers 16 are respectively installed at the upper ends of the operating shafts 13.

[0035] In this technical solution, when bending steel pipes of different specifications, the staff selects the operating shaft 13 and the operating roller 16 of the specified specification, embeds the connecting blocks 14 at both ends of the operating shaft 13 into the two mounting grooves 12, and then installs and fixes the two connecting blocks 14 through positioning bolts, so as to achieve the purpose of connecting the operating shaft 13.

[0036] In some technical solutions, refer to Figure 1 , two vertical plates 22 are provided at the upper end of the bottom plate 1, and a pressing structure is provided at the upper ends of the two vertical plates 22. The pressing structure includes two operating grooves 17, a pressing plate 18 and two adjusting cylinders 19;

[0037] The two operating grooves 17 are respectively formed at the upper ends of the two vertical plates 22. Both ends of the pressing plate 18 are respectively movably embedded in the two operating grooves 17. The two adjusting cylinders 19 are respectively installed on the outer sides of the two vertical plates 22, and the telescopic ends are respectively connected to both sides of the pressing plate 18.

[0038] In this technical solution, when bending a steel pipe, the two adjusting cylinders 19 on one side of the two vertical plates 22 are driven, and the two ends of the pressing plate 18 are driven by the two adjusting cylinders 19 to move in the two operating grooves 17 until the lower end of the pressing plate 18 fits the steel pipe, so as to achieve the pressing and fixing when bending the steel pipe.

[0039] In some technical solutions, refer to Figure 1 , the storage rack 3 is installed at the upper end of the support frame 2 by means of bolt connection. One end of the lead screw 9 is provided with an operating nut 20, and three storage grooves 21 are formed at the upper end of the storage rack 3.

[0040] Working principle: When bending a steel pipe, the operator first powers on this device. Subsequently, according to steel pipes of different specifications, the operator selects the operating shaft 13 and the operating roller 16 of the specified specification, and then inserts the connecting blocks 14 at both ends of the operating shaft 13 into the two installation grooves 12. Then, the two connecting blocks 14 are installed and fixed through positioning bolts, thus achieving the purpose of connecting the operating shaft 13. Subsequently, according to the specification of the steel pipe, the screw rod 9 in the adjustment groove 8 is rotated. Through the cooperation of the screw rod 9 and the internal thread formed on the moving block 10, the moving block 10 moves within the adjustment groove 8, changing the position of the second connecting shaft 11 and the distance between the two installation and operation components. Then, the steel pipe is placed on the upper ends of the support frame 2 and the storage rack 3. The steel pipe is stored through the three storage grooves 21 at the upper end of the storage rack 3. The two adjustment cylinders 19 on one side of the two vertical plates 22 are driven. Through the two adjustment cylinders 19, the two ends of the pressing plate 18 are driven to move within the two operation grooves 17 until the lower end of the pressing plate 18 fits the steel pipe, thus achieving the pressing and fixing during the bending of the steel pipe. Subsequently, the two driving members 5 at the upper ends of the two bearing brackets 4 are driven. Through the two driving members 5, the two first connecting shafts 6 are driven to rotate, causing the two rotating plates 7 to rotate following the two first connecting shafts 6. The installation and operation components located at the upper ends of the two adjustment components rotate around the installation and operation component between the two first connecting shafts 6 to perform the bending operation on one end of the steel pipe.
