[0061] For ease of understanding, the following is a working process of the circuit board sealing glue of this embodiment:

[0062] like Figure 1-Figure 7 As shown, first, according to the diameter of the steel pipe, the spacing between the upper straightening roller 10 and the lower straightening roller 4 is adjusted. When the position of the lower straightening roller 4 is adjusted, the first adjusting screw 803 is driven to rotate by the first adjusting device.

During the movement of the push block 802, the wedge structure pushes the first support shaft 7 to move in the vertical direction, thereby realizing the vertical position adjustment of the lower straightening roller 4.

[0063] When the position of the upper straightening roller 10 is adjusted, the turbine is driven to rotate by the third driving device, and the second adjusting screw 1401 is driven to move axially during the rotation of the turbine, thereby driving the second support shaft 13 to move axially, thereby realizing the upper straightening roller 10 The position is adjusted in the vertical direction;

[0064] When the angle of the upper straightening roller 10 or the lower straightening roller 4 needs to be adjusted, the adjusting rod 906 is pushed to move axially through the second adjusting device. During the movement of the adjusting rod 906, the rotating plate 903 is driven to rotate by adjusting the lead screw 905 and the connecting frame 904 through the positive and negative buckles. The rotating plate 903 drives the sleeve 901 to rotate synchronously. Since the sleeve 901 is connected to the first support shaft 7 or the second support shaft 13 through the connecting key 902, the first support shaft 7 or the second support shaft 13 is driven to rotate synchronously by a certain angle, thereby realizing the angle adjustment of the upper straightening roller 10 or the lower straightening roller 4;

[0065] After the spacing and angles of the upper straightening roller 10 and the lower straightening roller 4 are adjusted, the lower straightening roller 4 is driven to rotate by the lower drive shaft 6, and the upper straightening roller 10 is driven to rotate by the upper drive shaft 12. After that, the steel pipe to be straightened is passed through the upper straightening roller 10 and the lower straightening roller 4 in sequence for straightening.

[0066] In summary, the utility model provides a steel pipe straightening device, which solves the problem that the position adjustment and angle adjustment of the straightening rollers in the current steel pipe straightening device are troublesome, resulting in inconvenient debugging during use.
