[0028] In this embodiment, the transmission mechanism 7 includes a servo motor 71, a connecting tube 72 and a fixing bolt 73. The side of the lower straightening roller 6 is fitted with the connecting tube 72, and the side of the connecting tube 72 is penetrated by the fixing bolt 73. The other end of the connecting tube 72 is connected to the servo motor 71 through the fixing bolt 73. By setting the transmission mechanism 7, the transmission mechanism 7 can be connected to the upper straightening roller 13 and the lower straightening roller 6, thereby driving the upper straightening roller 13 and the lower straightening roller 6 to rotate.

[0029] In this embodiment, four groups of lower straightening rollers 6 and four groups of upper straightening rollers 13 are respectively provided, and eight groups of transmission mechanisms 7 are provided. The eight groups of transmission mechanisms 7 are respectively arranged on the sides of the four groups of lower straightening rollers 6 and the four groups of upper straightening rollers 13. The transmission mechanisms 7 on the sides of the upper straightening rollers 13 are telescopically connected to the workbench 2. Because four groups of lower straightening rollers 6 and four groups of upper straightening rollers 13 are provided, and eight groups of transmission mechanisms 7 are provided, the steel pipe can be better straightened.

[0030] In this embodiment, the adjusting mechanism 9 includes a rotating wheel 91, a disc 92, a rotating plate 93, a sliding column 94, a lifting plate 95 and a limiting column 96. The surface of the mounting frame 8 is rotatably connected to the rotating wheel 91, the back of the rotating wheel 91 is fixedly connected to the disc 92, the back of the disc 92 is fixedly connected to the rotating plate 93, the back of the rotating plate 93 is fixedly connected to the sliding column 94, the surface of the sliding column 94 is fitted with the lifting plate 95, and the side of the lifting plate 95 is fixedly connected to the limiting column 96.

At this time, the second mounting plate 10 fixedly connected to the lifting plate 95 will drive the upper straightening roller 13 to rise vertically. Example 2

[0033] On the basis of Example 1, a preferred embodiment of a straightening machine for steel pipe production provided by the utility model is as follows Figures 1 to 6 As shown: the top of the base 1 is located on the side of the workbench 2 and is fixedly connected to a guide plate 14, the top of the base 1 is located on the side of the guide plate 14 and is fixedly connected to a loading trough 15, the side of the loading trough 15 is fixedly connected to an electric push rod 16, and the output end of the electric push rod 16 is fixedly connected to a push plate 17.

[0036] Subsequently, the eight servo motors 71 are connected to the four lower straightening rollers 6 and the upper straightening rollers 13 through the connecting tubes 72 and the fixing bolts 73. At this time, the servo motors 71 are started to drive the upper straightening rollers 13 and the lower straightening rollers 6 to rotate. Then, the steel pipe is placed into the feeding trough 15, and the push plate 17 is driven to move to the left by the electric push rod 16, so that the push plate 17 pushes the steel pipe through the circular groove on the side of the guide plate 14 and transports it to the upper straightening rollers 13 and the lower straightening rollers. 6, at this time the purpose of feeding can be achieved, when the steel pipe is transported to contact with the upper straightening roller 13 and the lower straightening roller 6, the upper straightening roller 13 and the lower straightening roller 6 will straighten the steel pipe, and then send it out from the circular groove on the side of another set of guide plates 14. By setting two sets of guide plates 14, because the sides of the two sets of guide plates 14 are provided with circular grooves, a certain limit effect can be played on the steel pipe when conveying the steel pipe, thereby achieving the purpose of positioning and preventing the steel pipe from shifting during transportation.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
