10. The method for using a numerically controlled disc type roll bending machine for flexible conical members as claimed in claim 9, wherein said step S4 specifically includes:
t1, horizontally placing the metal plate to be processed at a designated position on a workbench, and preparing to roll after checking without errors;
t2, controlling the cone roller to press down and make rotary motion: starting a hydraulic station and independently supplying oil to a hydraulic motor in a case, wherein the hydraulic motor drives a universal shaft to rotate so as to drive a conical roller connected with the universal shaft to rotate;
t3, controlling the horizontal rotation of the workbench: starting a three-phase asynchronous motor for controlling the workbench to rotate, so that a metal plate to be rolled is slowly bitten into a roll gap working area between the conical roll and the workbench to start rolling;
t4, taking out the rolled metal plate: after the metal plate is rolled, closing the motor of the control workbench, stopping supplying oil to the hydraulic motor, and injecting oil to the lifting cylinder to lift the conical roller to separate the conical roller from the metal plate; after all the movement is stopped, the field worker takes out the rolled metal plate;
t5, changing the conical roller and changing the rolling thickness: and (4) rotating the conical roller to separate the conical roller from the rotating shaft in threaded connection with the conical roller, taking out the conical roller to replace the conical roller with another specification, and repeating the step S2 and the subsequent steps.
