In this way, under the control of the programmable controller, the processing end of the leaf spring is first turned by the workpiece seat 7 to correspond to the flat rolling space, then enters the flat rolling space under the transfer of the feeding vehicle 6 for flat rolling, and is moved out of the flat rolling space to the initial position by the feeding vehicle 6 after the flat rolling is completed, and then is turned by the workpiece seat 7 to correspond to the vertical rolling space, and finally enters the vertical rolling space under the transfer of the feeding vehicle 6 for vertical rolling, and is moved out of the vertical rolling space to the initial position after the vertical rolling is completed, so as to achieve the technical effect of automatically completing the flat rolling and vertical rolling of the processing end of the leaf spring in the same machine. When in use, the processed end of the leaf spring is fastened to the workpiece seat 7 toward the roller 2, and then the PLC controller 9 is started, and the processed leaf spring is removed from the workpiece seat 7 after the processing is completed.
