[0025] As Figures 1 to 5 shown, a steel pipe bending device includes a base 1, and also includes a first support plate 2, a second support plate 3, a driving member 10, a bending member 4, and a blocking member 8. The first support plate 2 is fixedly arranged at the bottom of the front end of the base 1, and the second support plate 3 is rotatably arranged at the top. The driving member 10 is arranged on the base 1, and the output end of the driving member 10 is provided with the bending member 4. The bending member 4 is located between the first support plate 2 and the second support plate 3. A number of mounting holes 7 are symmetrically and correspondingly arranged on the first support plate 2 and the second support plate 3 with respect to the bending member 4. The mounting holes 7 on the first support plate 2 and the second support plate 3 are arranged at an included angle; there are two blocking members 8, and the lower ends of the two blocking members 8 are respectively inserted into two symmetric mounting holes 7 on the first support plate 2, and the upper ends of the two blocking members 8 are respectively inserted into two corresponding mounting holes 7 on the second support plate 3.

[0026] By setting the bending member 4 and the blocking member 8, and arranging mounting holes 7 on the first support plate 2 and the second support plate 3, the mounting position of the blocking member 8 can be adjusted. Furthermore, bending of the steel pipe at different angles can be achieved. Meanwhile, through the first support plate 2 and the second support plate 3, the steel pipe can be clamped vertically, and the bending member 4 and the blocking member 8 clamp the steel pipe horizontally, making the steel pipe more stable and less likely to shake during bending, thus resulting in a better bending effect.

[0027] In this embodiment, the bending member 4 includes a connecting rod 11 and an arc-shaped block 12. The two ends of the connecting rod 11 are respectively connected to the output end of the driving member 10 and the concave part of the arc-shaped block 12, and an arc-shaped clamping groove 13 is formed at the convex part of the arc-shaped block 12. The provision of the arc-shaped clamping groove 13 facilitates clamping of the steel pipe to be bent when the driving member 10 drives the bending member 4 to move.

[0028] The blocking member 8 includes a prism block 14, a connecting block 15, and a plug-in block 16. Three bending pad holes 17 are formed on the side surface of the prism block 14. The cross-sections of the three bending pad holes 17 in the vertical direction are respectively a triangle and two sectors, and the sizes of the two sector cross-sections are different. A connecting block 15 is provided at each of the upper and lower ends of the prism block 14, and a plug-in block 16 is provided at the end of each of the two connecting blocks 15 away from the prism block 14. The plug-in block 16 is adapted to the mounting hole 7. The three bending pad holes 17 can accommodate steel pipes to be bent of different specifications. The blocking member 8 is movably clamped in the mounting hole 7, facilitating adjustment of the position of the blocking member 8 to meet the requirement of bending the steel pipe into different angles.

[0029] The arc-shaped clamping groove 13 of the arc-shaped block 12 is adapted to the position of the bending pad hole 17.

[0030] In this embodiment, a first support seat 5 and a second support seat 6 are respectively arranged at the front and rear ends of the base 1. The driving member 10 is arranged between the first support seat 5 and the second support seat 6, and the output end of the driving member 10 passes through the first support seat 5 to arrange the bending member 4.

[0031] A first support plate 2 is horizontally and fixedly arranged at the front end of the bottom of the first support seat 5. A connecting shaft 9 is arranged above the first support seat 5 along the direction perpendicular to the output direction of the driving member 10. Rotating rods 22 are rotatably arranged at both ends of the connecting shaft 9, and the ends of the two rotating rods 22 away from the connecting shaft 9 are connected to the second support plate 3. When the device is not in use, the second support plate 3 is rotated above the driving member 10. When in use, the second support plate 3 is rotated above the first support plate 2, and the first support plate 2 and the second support plate 3 clamp the steel pipe to be bent in the middle.

[0032] The driving member 10 is a hydraulic cylinder or a pneumatic cylinder.

[0033] In this embodiment, a pressing member is further included. The pressing member includes a support tube 18, a pressing rod 19, and a pressing plate 20. The support tube 18 is arranged on the second support base 6, and the opening of the support tube 18 faces the side close to the bending member 4. One end of the pressing rod 19 is inserted into the opening of the support tube 18, and the pressing plate 20 is used to support the other end of the pressing rod 19 and is arranged on the second support plate 3. By providing the pressing member, when bending the steel pipe, one end of the pressing rod 19 is inserted into the opening of the support tube 18, and the other end presses the pressing plate 20 on the second support plate 3, so as to fix the second support plate 3 above the first support plate 2, preventing the second support plate 3 from rotating when the steel pipe is bent and affecting the bending effect.

[0034] In this embodiment, to facilitate the movement of the device, universal wheels 21 are provided at the bottoms of the base 1 and the first support plate 2.

[0035] Although the specific implementation manners of the utility model are described above in conjunction with the drawings, it is not a limitation to the protection scope of the utility model. Based on the technical solution of the utility model, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the utility model.
