[0022] The working principle of the stainless steel pipe correction equipment is as follows: In the process of stainless steel pipe machining, when the stainless steel pipe needs to be straightened, the handle on the rear side of the adjusting frame 47 is pulled to move the adjusting frame 47 rearward, overcoming the elastic force of the limiting spring 6, so that the guide slide column 5 slides in the guide slide hole on the rear side of the drive shell 41. The upper end of the adjusting frame 47 cancels the limiting of the inclined plate 45, and under the elastic force of the return spring 46, the inclined plate 45 drives the outer hexagonal column 44 to move upward, and the lower end of the outer hexagonal column 44 is away from the inside of the inner hexagonal column one 42. At this time, the position of the drive shell 41 can be adjusted forward and backward. During the adjustment process, the transmission worm wheel 12 and the worm 49 rotate relatively, and according to the size of the stainless steel pipe, the appropriate straightening roller 3 is selected to correspond to the vertical position of the drive shell 41. After the adjustment is completed, the adjusting frame 47 is loosened, and under the elastic force of the limiting spring 6, the adjusting frame 47 moves forward to reset. The horizontal plate of the adjusting frame 47 exerts force on the inclined surface of the inclined plate 45, overcoming the elastic force of the return spring 46, pushing the inclined plate 45 and the outer hexagonal column 44 downward, and the outer hexagonal column 44 is inserted into the inside of the inner hexagonal column one 42 corresponding to the vertical position. Under the connection of the outer hexagonal column 44, the inner hexagonal column one 42 and the inner hexagonal column two 43 corresponding to the vertical position are rotated synchronously. When straightening, the PLC controller 9 starts the drive motor 10, the output shaft of the drive motor 10 drives the worm 49 to rotate, and through the meshing connection of the worm 49 and the transmission worm wheel 12, the transmission worm wheel 12 drives the transmission worm 13 to rotate. Through the meshing connection of the transmission worm 13 and the four worm wheels 48, the worm wheels 48 inside the inner hexagonal column one 42 and the corresponding position straightening roller 3 are driven to rotate. The two straightening rollers 3 corresponding to the horizontal position are a group, and the two straightening rollers 3 in the same group rotate relatively, and then the stainless steel pipe is inserted into the two straightening rollers 3 corresponding to the horizontal position. The relatively rotating straightening rollers 3 are used to convey the stainless steel pipe, and in the conveying process, the stainless steel pipe is straightened by the multiple straightening rollers 3. In the straightening process, the electric push rod 88 is started, the telescopic end of the electric push rod 88 drives the adjusting plate 85 to move forward and backward, and under the elastic connection of the pressing spring 87, the frame 83 moves forward and backward, the slide column 84 slides in the frame 83, and the rotating frame 81 rotates around the rotating shaft to change the distance between the two pressing rollers 82 in the same installation shell 2. When the pressing roller 82 contacts the stainless steel pipe, with the continuous movement of the adjusting plate 85, the elastic force of the pressing spring 87 is overcome, and the pressing spring 87 is retracted. Under the elastic force of the pressing spring 87, an oblique force is applied to the pipe in the axial direction of the stainless steel pipe, the stainless steel pipe is preliminarily straightened, and the effect of single straightening of the stainless steel pipe is improved.
