[0016] In the working process of the piston rod blank straightening device of the present invention, the PLC controller controls the electromagnet 26, and the piston rod blank is fixed in the sleeve 25 through the attraction generated by the electromagnet 26. The PLC controller controls the motor 211 to work and drives the fixing device 2 to rotate through the gearbox 212. The fixing device 2 drives the piston rod blank to rotate. When the deformed part of the piston rod blank abuts against the reference seat 42, the piston rod blank will tilt forward (in this process, the piston rod blank drives the upper base 24 to tilt through the sleeve 25, and the three-dimensional angle sensor 27 sends the angle value of the inclination of the upper base 24 to the PLC controller). When the angle value measured by the three-dimensional angle sensor 27 is the maximum value, the PLC controller controls the piston rod of the hydraulic cylinder 32 to extend and drive the pressure seat body 33 to move toward the piston rod blank, thereby realizing the straightening of the piston rod blank.
