Intelligent stepping adjustment method of large ball press machine based on current control

The invention discloses an intelligent stepping adjustment method of a large ball press based on current control, which is characterized in that the frequency of a feeding spiral frequency converter is synchronously adjusted according to the current of a pre-pressing screw while the current of a main motor and the frequency of the pre-pressing screw frequency converter are mutually fed back and interlocked for adjustment. According to the invention, all units of the control system are integrated together, the chain feedback relationship between devices is enhanced, the cooperative cooperating capability between the devices is enhanced, and unstable operating of the system caused by too large or too small work of a single device is avoided, so that coordinated and stable operating of the devices is finally realized; the corresponding frequency is automatically adjusted according to the current of the motor during the operating period of the equipment, so that the purposes of intelligent control and closed-loop
