The sliding columns are symmetrically arranged about the center of the device plate, and the upper end face of the sliding column is fixedly connected to the top surface of the processing chamber.

[0006] The above technical solution facilitates the straightening of steel pipes.

The sensor transmits a signal to the control system, which adjusts the drive motor according to preset parameters, thereby achieving automatic adjustment of the pressure roller's downward pressure. This design not only improves the flexibility of the straightening machine but also ensures the accuracy and stability of the steel pipe during the straightening process.

[0009] As a preferred embodiment of this utility model, a No. 1 processing seat is fixedly connected to the lower end face of the limiting post, and a pressure roller is rotatably connected to the lower end face of the No. 1 processing seat.

[0014] The above technical solution makes the straightening process more stable, further improving the overall performance and straightening effect of the straightening machine.

[0018] The above technical solution ensures that the steel pipes can accurately enter the straightening machine, further improving the automation level and applicability of the straightening machine.

[0019] Compared with existing technologies, the advantages of this invention are: the device can automatically adjust the pressure during the steel pipe straightening process, ensuring uniform force on the steel pipe and effectively avoiding deformation or damage to the steel pipe caused by improper pressure, thus greatly improving straightening accuracy and finished product quality. At the same time, the device has a compact structure, is easy to operate, reduces the labor intensity of workers, and improves production efficiency.

[0020] 1. When the pressure roller straightens the steel pipe, the pressure roller outputs a reverse force to the pressure sensor through the No. 1 processing seat and the limit column. This reverse force is accurately captured by the pressure sensor and converted into an electrical signal. This electrical signal is then transmitted to the control system, which has a preset pressure threshold range. If the detected reverse force exceeds this range, the control system will immediately activate the adjustment mechanism and control the drive motor.

[0021] 2. The drive motor drives the rotating shaft to rotate in the opposite direction. The rotating shaft drives the threaded rod to rotate through the helical gear. The threaded rod drives the equipment plate to move upward, thereby adjusting the downward pressure of the pressure roller until the reverse force returns to the preset pressure threshold range. This process ensures that the pressure on the steel pipe is always in the optimal state during the straightening process, effectively avoiding the problem of steel pipe deformation or poor straightening effect caused by excessive or insufficient pressure. In addition, the design of the auxiliary feeding hopper enables the steel pipe to be effectively guided and positioned before entering the straightening machine, further enhancing the stability and accuracy of the straightening process.

The sensor transmits the signal to the control system, and the control system adjusts the transmission motor 4 according to the preset parameters, thereby realizing the automatic adjustment of the pressing amount of the pressure roller 12. This design not only improves the flexibility of the straightening machine, but also ensures the accuracy and stability of the steel pipe during the straightening process.

[0032] The lower end face of the limiting post 10 is fixedly connected to the No. 1 processing seat 11, and the lower end face of the No. 1 processing seat 11 is rotatably connected to the pressure roller 12, which facilitates the straightening quality and enables the steel pipe to achieve higher precision and better surface quality after straightening.

[0037] Working principle: When the pressure roller 12 straightens the steel pipe, the pressure roller 12 outputs a reverse force to the pressure sensor 19 through the first processing seat 11 and the limiting column 10. This reverse force is accurately captured by the pressure sensor 19 and converted into an electrical signal. This electrical signal is then transmitted to the control system, which has a preset pressure threshold range. If the detected reverse force exceeds this range, the control system will immediately activate the adjustment mechanism and control the drive motor 4.

In addition, the design of the auxiliary feeding hopper 18 enables the steel pipe to be effectively guided and positioned before entering the straightening machine, further enhancing the stability and accuracy of the straightening process.
